Technological advances in both building design and the equipment used in modern slaughter and processing facilities has provided new opportunities for establishment operators to function at much higher production volumes. Efficiency in plant monitoring methods has also changed dramatically through the application of science based quality assurance and food safety programs such as the Hazard Analysis Critical Control Point (HACCP) System. These changes to plant operating methods also make it necessary to adjust and modernize the current method and approach to food inspection systems by the Canadian Food Inspection Agency (CFIA) in a modern slaughter facility in order that the Agency may continue to deliver reliable scientifically based methods of food safety inspection at these higher volumes.
The High Line Speed Inspection System (HLIS) is one such system that allows beef slaughter facilities to operate at enhanced line speeds. This system can be implemented in federal establishments that slaughter steers, heifers and mature cattle provided the facility operator agrees to certain facility and equipment modifications as well as specific process controls to ensure that the integrity of the product is maintained when it is produced under these high volume conditions. Before the HLIS is adopted in any slaughter facility it is imperative that clear dialogue occurs between the CFIA and the facility operator regarding the resource impact of plant monitoring responsibilities, training needs, financial and human resource commitments.
The HLIS incorporates modifications to the traditional beef post-mortem inspection procedures and inspection station configurations by establishing presentation standards (PS) for the heads, viscera, and carcasses prior to inspection and finished product standards (FPS) for carcasses.
The HLIS provides an opportunity for the establishment to adjust to assuming a greater responsibility for managing the quality and safety of their product through an initial one time CFIA certified training program for their plant personnel. The CFIA provides this initial training for any starting facility so an initial block of trained plant personnel may be established. Further training is then assumed by the establishment. This format provides a co-operative and shared inspection approach to the slaughter and carcass dressing procedures. Significant inspection station reductions are realized at higher line speeds due to efficiencies gained through minimized product handling and a shift toward greater responsibility on the part of the company to present and manage its own product.
Under this program the operator will be responsible for the identification and removal of defects that result during live handling, humane stunning, or dressing operations collectively referred to as "manufacturing defects". The operator will also assume responsibility for the removal of certain minor specified trimmable pathological conditions (TPCs). Removal of these defects will be accomplished by plant personnel that have undergone a training and accreditation program to become designated accredited trimmers, presenters, monitors and detectors. The establishment employee training program is to be established in writing and approved by the VIC with consultation of the Area Red Meat Program Specialist and the Regional Veterinary Officer (RVO).
1.1 Written Quality Assurance Program/ HACCP System (FSEP)
The HACCP System should reflect distinct levels for managing and monitoring the HLIS program. Normally, Plant Production performs product control and monitoring (monitoring by production personnel may be optional if performed by Quality Control (QC) personnel), QC performs verification and CFIA functions in an oversight capacity to monitor and verify the overall testing activities of both groups. For the system to operate properly, each of these 3 levels of evaluation needs to function independently while remaining part of one system.
In certain facility settings it may be more advantageous and effective to have only the QC department responsible for monitoring and verification procedures provided these activities are performed by different individuals.
The entire slaughter process may be divided into operational zones for easier control and monitoring of the program if the company so chooses. Again, this should be reflected in the written program along with all monitoring/process control points, employee training and accreditation programs and submitted to the VIC for review and approval.
1.2 Product Testing
Under traditional inspection, the VIC has the authority to require line speed reductions or stoppages as well as other corrective actions when post-mortem inspection cannot be adequately performed at the current line speed because of preparation or presentation deficiencies or because of disease incidence. Under HLIS procedures, the VIC or delegate still retains this final authority to stop the line or reduce its speed if it is evident that the operator's efforts are failing to manage the problem. Due to the high volume and rapid line speeds that these plants operate at, all alternative corrective actions to manage the problem should be thoroughly considered before the decision to stop or reduce line speed is taken. If it is apparent from performance data that an operator cannot consistently perform at an Acceptable Quality Level (AQL) for any of the process control steps in HLIS, the line speed maximums shall be re-assessed by the VIC and the facility operator. See also note below.
Only designated trained industry personnel shall perform the tests described in the program. The test results are recorded in company logs/record sheets. It is normally the QC monitor's responsibility to review the entries made in the records for timeliness and accuracy and to assure that appropriate action is taken when the standards are not met. The QC monitor (or designated equivalent) will also conduct independent tests and compare the results of these with those of production personnel if applicable. In turn, CFIA personnel will periodically monitor the operator's quality control program by monitoring production activities, reviewing company records and by comparing and correlating the results of their own tests with those conducted by Production and/or QC personnel.
Unless otherwise stated in this policy, the CFIA will perform on a random basis a minimum of one correlation test during each half shift in order to validate operator results for the following; Presentation, Shewhart Control Chart and carcass FPS testing. At the discretion of the VIC or delegate, additional correlation tests may be performed during a production shift if it is determined that product performance or test results are being affected or influenced by unusual or extraordinary circumstances or poor operator performance.
The VIC shall have discretion in initiating corrective action through consultation with the operator if it is determined that unsatisfactory or poor product/employee performance is occurring during non testing intervals or there is a general difficulty in achieving consistent satisfactory test score results. Repetitive occurrences shall be documented on the appropriate record and corrective action shall be undertaken by the operator or at the direction of the VIC or delegate.
If it becomes apparent from historical performance data (5 consecutive shifts or more) that an operator cannot perform consistently* at an established AQL for any of the process control steps in the HLIS program and previous corrective action undertakings by the operator have not provided long term resolution to the problem, then the line speed maximums for the process step(s) involved shall be re-assessed by the VIC/RVO and the operator and reset to a lower maximum level, using an initial increment reduction of 10%.
If the initial line speed reduction does not provide satisfactory improvements within the first operating half a shift a further reduction(s) shall be imposed until the accepted AQL for the affected process step(s) has been re-established. From the time a satisfactory line speed and associated AQL is established it shall remain in place for a minimum of 5 consecutive working shifts.
If during this reduced line speed period the operator can clearly demonstrate that the initial cause of the original under performance was due to a discrete and specific operational issue that has subsequently been fully corrected the operator may then request that the VIC immediately commence to restore line speeds to their original values in the same increments that they were reduced.
Once restored, should the same or similar under performance issues again arise within a 5 consecutive shift period the line speed shall be immediately reduced to it's former level and shall remain at this or a lesser line speed until 5 consecutive shifts have been completed. At that point, the operator and the VIC/RVO shall consult and agree as to whether or not it is appropriate from records of performance for the past 5 shifts to restore line speeds to their original values.
If the CFIA's correlation test result fails to correlate with that of the monitor an immediate retest shall be performed and QC will be notified. Two consecutive non matching correlation tests between the operator and the CFIA will require that corrective actions be initiated by the operator (if applicable) based on the results of the second CFIA test which shall be taken as the correct score. The CFIA will monitor all Plant Production and QC corrective action activities to ensure program requirements are met. The discrepancy in scoring results shall be investigated and reconciled in consultation with the VIC after all required corrective actions have been implemented.
For all AQLs (or equivalent) assigned to a process control step in the HLIS program a participating operator shall be expected to achieve at least the 80th percentile of performance on average when results from the CFIA and the operator are jointly examined over a period of 5 consecutive working shifts or longer.
1.3 General Responsibilities
Once an operator has had its application for HLIS inspection staff resources approved within the Region it will then be subject to a review process to confirm that it can provide adequate resources, materials and facilities to meet the requirements of the HLIS policy on an ongoing basis. In addition, those process steps that will be subject to a performance standard under the HLIS policy shall first have their existing performance level assessed. This shall be done by gathering sets of baseline data prior to implementing any process controls at these locations under the HLIS policy.
The HLIS policy introduces the application of process controls at certain critical locations along the processing line. When an operator initiates operations under the HLIS format he may elect to use the national performance standards or alternately gather and use their own in-plant data to establish their process control performance level. For the latter, in order to fairly assess these control points, it is important to know what level the operator was performing at prior to entering the HLIS program and to also know at what level it is able to maintain itself. Therefore performance data based on a minimum of 50 sample sets taken at each designated process step gathered over a minimum of 10 working days will be required before the operator may begin to apply the HLIS process controls at these locations. Following this, the operator will be allowed 2 months to adjust its operations to meet the declared national performance standards for SPC testing, dehiding performance through Shewhart testing and FPS food safety and FPS other carcass defects. A maximum of 6 months will be allowed for an operator to meet the national AQLs for presentation of carcasses and their parts.
Facility and resource requirements
Under the HLIS Program, Plant Management shall agree to provide an approved facility that meets the CFIA HLIS and Meat Hygiene Manual of Procedures (MOP) construction standards. Before a facility can be approved for HLIS operations it shall undergo a facility review by an Area Program Specialist and the RVO along with the VIC to validate that all HLIS facility standards are in compliance with the policy requirements. See form HLIS 005: HLIS Beef Program - Facility Assessment. Once the facility review is satisfactorily completed a signed letter of commitment from a responsible company officer shall be forwarded to the VIC. This letter addresses the following items:
- The operator agrees to maintain a facility that meets the criteria referenced in the HLIS policy and the MOP once the HLIS program application is approved.
- The operator agrees to provide sufficient material(s), financial and human resources, to carry out the various functions and responsibilities designated to him under the HLIS Program.
- The operator agrees to carry out all functions and responsibilities assigned to him under the HLIS program and to take all necessary actions as indicated therein during the operation of the HLIS program.
- Should the operator decide to withdraw from the HLIS program, the CFIA shall be provided with written notification of the operator's decision ten working days prior to the final scheduled day of HLIS operations. After 6 months of continuous absence from the HLIS program the operator shall lose its certification as an approved HLIS facility.
- While certified as HLIS, all slaughter operations shall be performed in accordance with the HLIS program.
The letter of commitment shall be renewed at least annually or upon departure of the responsible signing official.
The application of this HLIS policy manual must at all times remain in conformity with the Meat Inspection Act, Meat Inspection Regulations, 1990, Meat Hygiene Manual of Procedures as well as the Food Safety Enhancement Program. Unresolved differences in the interpretation of the application of the HLIS policy between CFIA personnel and the operator may be referred to the CFIA headquarters for written clarification. During this interim period the decision of the VIC/RVO shall prevail.
2.0 Personnel Requirements
2.1.1 Training Protocol for Accredited Plant Employees
An important part of the success of HLIS is the training and accreditation of key plant personnel. The positions for which accreditation is required are the following: presenters, detectors, trimmers, and monitors. Training and accreditation for the initial group of plant employees will be done by CFIA certified staff using the CFIA National Training Program. Accreditation requires successful completion of both a theoretical classroom session as well as a practical evaluation. All subsequent training of new staff will be performed by accredited plant personnel through the operator's HLIS training program. Thereafter, CFIA accredited personnel under the supervision of the VIC will only monitor the training of plant personnel as well as the plant's written program to ensure sufficient training standards are being maintained. The VIC or delegate is responsible for approving the operator's HLIS training program. At least once a year the VIC shall ensure that it is current and complete, including records of all accredited employees.
Should 6 or more consecutive calendar months lapse in which any accredited plant employee is not exposed to the application and/or practices of the HLIS program any such affected employee will be required to undergo a refresher training course and satisfactorily demonstrate their knowledge and application of the HLIS program before being re-accredited. The QC department shall be responsible for monitoring and maintaining the accredited status of their employees. The VIC has the right to decertify any accredited plant employee by having their name removed from the company eligibility roster. There must be demonstrable factual information to show that the individual is not able to meet the required standards. A protocol describing the process of deaccreditation and retraining must be included in the operator's HLIS written program.
126.96.36.199 Plant Employee Accreditation
- Trimmers(see also section 4.3.1 - Duties of Trained/Accredited Plant Personnel)
In order to accredit an employee as a "trimmer" the operator shall demonstrate that the following conditions are met:
- The accredited trimmers are employees who are trained and accredited as proficient in the detection and sanitary removal of dressing non conformances and Category I trimmable pathological conditions (TPCs).
- The operator takes full responsibility for the training/re-training of accredited trimmers as well as for testing for proficiency as per the CFIA HLIS training program criteria.
- A current written training program signed off by a responsible plant officer, which outlines the operator's training and evaluation procedures is maintained on file and approved by the VIC and shall be made available upon request.
- Maintenance of a current roster of employees who have passed the plant accreditation process is maintained on file and a current copy of the roster shall be submitted to the VIC at least quarterly and be available on demand should the need to consult the roster arise during the intervening period.
- Detectors (see also section 4.3.1 - Duties of Trained/Accredited Plant Personnel)
As for section 188.8.131.52 a) Trimmers
- Presenters (head, viscera and carcass)
- The accredited presenters are proficient in preparing/orienting the appropriate carcass parts in a manner that conforms to minimum performance standards. Items ii - iv under section 184.108.40.206 a) Trimmers are applicable.
- Process control monitors (Shewhart control chart, Presentation, FPS for FS and other carcass defects [including Rework]).
- The process control monitors shall be proficient in their knowledge, understanding and application of the respective detection, scoring, recording and corrective action activities associated with the described positions for which they assume responsibility. Items ii - iv under section 220.127.116.11 a) Trimmers are applicable.
When an accredited plant employee is required to perform more than one task, be it another accredited task or non accredited task relating to that person's job, that employee shall not be distracted by additional responsibilities that would prevent him/her from otherwise satisfactorily performing the accredited functions of the position as if it were his/her sole responsibility. For example, the detector/trimmer function is often assigned as a joint responsibility. This may only occur if the above conditions can be met and there is an auditable means available for assessing detection and trimming performance.
18.104.22.168 CFIA Employees
- Indeterminate Employees
CFIA employees are initially trained and certified through the CFIA National Certification Program. Should a lapse of 6 consecutive calendar months or more occur where a certified CFIA inspector has not been exposed to the principles and applications of the HLIS program they shall be required to undergo a refresher training course in accordance with the HLIS training program. Under the direction of the VIC or delegate, the candidate shall satisfactorily demonstrate their knowledge and application of the program through a written and practical test process.
- Seasonal/Temporary Employees
CFIA employees in this category will be trained for limited participation in the HLIS program. They shall be trained to understand and perform the necessary post-mortem functions (see the relevant CFIA training modules) but shall not be responsible for floor monitoring activities. They shall be responsible for understanding and reporting on the activities of those plant employees who are improperly preparing carcasses and their parts for post-mortem inspection. Any such employee who works in this capacity for greater than 6 continuous calendar months (183 continuous calendar days) shall receive full HLIS certification training.
2.2 Plant Operations
2.2.1 Plant Production
Plant Production designated staff shall assume the following responsibilities:
- Use qualified and trained personnel to carry out the assigned functions under the HLIS program.
- Train and assign plant employees in the proper presentation of heads, viscera and carcasses for inspection.
- Use accredited personnel for detecting/trimming dressing non-conformances and trimmable pathological conditions.
- Make available to CFIA inspection staff all test results from PS, FPS food safety (FS) and other carcass defects (OCD), Control Charts and QC checks, if applicable.
2.2.2 Plant Quality Control

- Make available to the CFIA inspection staff all test results from PS, FPS food safety and non food safety, Control Charts and QC checks, if applicable.
- Design, implement and maintain a HLIS Employee Accreditation Program for presenters, detectors, trimmers and process control monitors. The program shall be written and shall be reviewed and approved by the VIC.
2.2.3 CFIA Inspection Staff
The CFIA inspection staff shall assume the following responsibilities:
- Make available sufficient certified CFIA HLIS inspectors to perform all required duties at designated CFIA inspection stations including monitoring and correlation testing of Presentation Standards, Shewhart Control Chart Performance Standards, Finished Product Standards and QC and Plant Production test monitoring program in accordance with the Inspection Stations and Staffing Requirements outlined in Table 4.1A & Table 4.1B. The CFIA floor monitoring function will be fulfilled as part of the CFIA inspection station rotation.
3.0 Facility Requirements
In addition to inspection facilities required under the Meat Inspection Act, Meat Inspection Regulations, 1990 and Meat Hygiene Manual of Procedures, the following additional facilities and equipments are required for the implementation of the HLIS program:
Each carcass inspection station shall be equipped with a distortion free mirror(s) of sufficient size to provide a clear unobstructed view of the entire dorsal surfaces of the largest carcasses processed and provide a horizontal width at least equivalent to that of the CFIA inspection station(s) (2 metres x 2 metres is a recommended size/station). The mirror system can be a one piece tiltable mirror or a two-piece vertical (to view the dorsal surface of the carcass) canted (to view the posterior surface of the carcass) system. In either case the mirror system shall be placed far enough from the vertical plane of the carcass to allow the carcass to be turned without contacting the mirror but close enough to provide the required view of the carcass.
A minimum of 1000 lux of shadow-free lighting with a minimum Colour Rendering Index (CRI) of 85 is required at each post-mortem inspection station and associated company detection station, Shewhart carcass inspection station and each product reinspection station. In addition, a diffuse light source (such as a double tube fluorescent light fixture) shall be mounted at the top of the carcass mirror to provide a minimum of 1000 lux of lighting at the carcass shoulder level. Directional lighting may also be required at the carcass inspection station to ensure that sufficient lighting is provided inside the thoracic cavity of the carcass as it passes through the inspection zone.
- Carcass centre spacing
The minimum distance between beef carcass centres shall be 1.83 metres (6.0 ft).
- Table width
The minimum moving table width shall be 1.52 metres (5 ft). However, the table shall be sufficiently wide enough and sufficiently long enough to provide a drag space to allow for the proper inspection of viscera and prevent any interference and/or common contact from other parts of the same carcass or from other carcasses.
- CFIA inspection/plant employee space requirements
Adequate unencroached space shall be available for those plant employees who are responsible for proper presentation of heads and viscera for inspection as well as for the performance of presentation testing. Presentation testing requires a minimum of 92 cm (3 ft) without encroachments. This space should be located next to and upstream from the various inspection stations. Each head, viscera and carcass CFIA inspection station should be of the required length and preferably adjustable, without encroachments.
Must be of sufficient size and readily accessible to an inspector's working position.
- Shewhart test stations
The Shewhart inspection stand or allocated space shall conform with the space requirements of the presentation station, and also with the lighting standards required for final carcass inspection. It shall be positioned close enough to the carcass line (comfortable arm's length) to satisfy Occupational Safety and Health (OSH) requirements and so the evaluator may manipulate the carcass if necessary. It shall be located directly after the process step(s) it evaluates and prior to any further alteration to the product. This provides for effective evaluation of the process step and a timely response interval when corrective actions are required. A sanitizer is not required if trimming is not performed. Beef operators shall provide 3 Shewhart test stations. Two stations shall evaluate hide removal. These shall be located so they can evaluate the hind (rump/bung) and front (shank/brisket) quarters after hide removal and prior to the pre-evisceration wash if it exists. The third station shall evaluate the evisceration procedure.
- Head inspection station
The space required to perform head inspection is based on minimum unobstructed work space for head inspectors when heads are presented on 1.22 metres (4 ft) centers. If spacing is greater than 1.22 metres (4 ft), extra work space may be required. See Table 3.1A & Table 3.1B.

- Viscera inspection station
The requirement for the beef viscera inspection station is 2.44 metres (8 ft) per inspector.
- Carcass Finished Product Standards test stations
The evisceration floor carcass FPS test station shall be located off the main rail and be adequate in length to collect, inspect and hold the required number of carcasses for a sample set based on ISO sampling plan 2859-1. On line inspection may be performed in a registered facility but only after an acceptable study has been performed and approved by National Headquarters to demonstrate its equivalency to off-line inspection. It is necessary that it be located downstream from all company trimming procedures. This station must also be equipped with a permanent platform preferably adjustable with enough room to allow 2 people access to all levels of the carcass. It shall be equipped with a sanitizer, soap and towels and safety rails, have a minimum 1000 lux of shadow-free lighting with a minimum CRI of 85 and have a clipboard holder for holding recording sheets.
The inside/outside carcass inspection platform shall be large enough to accommodate 2 persons, shall preferably be adjustable, shall be designed and equipped with safety devices ensuring OSH requirements are met, and shall allow for quick exit. The platform shall be located opposite to the mirror prior to or after the splitting saw and in a position such that the carcass inspector can easily view the viscera table and communicate with the viscera inspector. Alternatively, the operator may develop and implement a program, approved by the CFIA, to control the viscera associated with any carcass held at the inside/outside carcass inspection station. Each platform is to be equipped with a sanitizer, sink, soap, and towels. The sink shall be installed on the outside of the platform, not inside. The platform shall be a minimum of 0.75 metres (2.5 ft) wide and 1.83 metres (6 ft) long with the lengthwise dimension running parallel to the moving chain. Unhampered access to and from the platform shall be provided.
If adjustable, as measured from the rail, the upper platform height can be less than or equal to 2.54 metres (100 inches). The lower platform can be greater than or equal to 2.85 metres (112 inches). If adjustable, as measured from the floor, the upper platform can be greater than or equal to 1.17 metres (46 inches). The lower platform height can be less than or equal to 83.82 cm (33 inches).
- Carcass cooler rework/trim station
The carcass cooler reinspection station may be a permanent trim station or mobile station. The location of the stand shall be in an open area, avoid common contact and shall receive the final approval of the VIC with consultation from the Area Red Meat Program Specialist and/or the RVO, as required. Each stand must adhere to OSH safety guidelines and be fully equipped with a sanitizer, record/clipboard holder and sufficient lighting (1000 lux) shall be provided with convenient access to handwash facilities.
- Carcass rework holding capacity
Sufficient cooler space and rails shall be provided to separate detained lots of carcasses that have been identified for rework or reconditioning procedures by the CFIA or the operator from those carcass lots that have been approved. An acceptable area that will allow effective rework of the detained lot shall be provided.
- Line Speed Indicator
An accurate digital line speed indicator for the carcass evisceration chain must be provided on the slaughter floor so that it can be easily read by the inspectors performing presentation testing.
4.0 General Inspection Procedures
4.1 CFIA Post-mortem Inspection Procedures
Under HLIS there are a number of changes that affect post-mortem carcass and parts presentation methods when compared to those procedures that occur in plants under traditional inspection. With respect to specific CFIA post-mortem inspection tasks in a HLIS facility all procedures remain essentially the same as in traditional inspection but with a notable reduction in manipulation of carcasses and their parts resulting in a reduction of the number of required inspection stations at higher line speeds.
For inspectors working in an HLIS slaughter establishment, all the post-mortem inspection tasks stated in Chapter 17 of the MOP must be performed except for the following differences:
- The inspector observes the surfaces of the tongue after it has been palpated by a plant employee. Routine palpation of the tongue by the inspector is not required.
- The inspector observes the cut surfaces of the internal pterygoid and external masseter muscles after they are incised by a plant employee. Further routine incision of these muscles by the inspector is not required.
- The inspector incises and observes the cut surfaces of parotid, medial retropharyngeal, and mandibular lymph nodes.
- The inspector observes the lateral retropharyngeal (atlantal) lymph nodes. Routine incision of these lymph nodes is not required.
Thoracic and abdominal viscera inspection
- The inspector observes and palpates the dorsal surfaces of the lungs. The ventral surfaces of the lungs are not routinely observed.
- The inspector observes the hepatic lymph node. Routine incision of this lymph node is not required.
- The inspector observes the internal, external and cut surfaces of the heart after an establishment employee presents the opened heart for inspection. Further routine incision of the heart by the inspector is not required.
- Inspection of the kidneys must be performed on the viscera inspection table.
- The inspector visually examines the spleen.
- Carcass inspection may be conducted on an unsplit carcass in the case of steers and heifers, but must be conducted on the split carcass of mature animals (cows and bulls).
CFIA inspectors working on line shall only be responsible for identifying Category II Trimmable Pathological Conditions (TPCs) and not for conditions that are classified as dressing defects or Category I TPCs (see Table 7.1). Identification and removal of defects such as eyelid, hair, hide, etc. are the responsibility of the operator. It is the responsibility of the plant Detector to identify defective conditions and decide if the carcass is to be railed out for trimming or left on line. It may not be possible at higher speeds for one person to identify, mark and trim carcasses. Therefore once determined by the operator or VIC that an individual cannot perform multiple tasks effectively, the Detector(s) shall only identify and mark dressing defects and Category I TPCs and one or more accredited Trimmers shall be in place to effectively perform the sanitary removal of the identified defects.
CFIA Inspection Station and Staffing Requirements - Beef
The staffing numbers listed in these tables are the minimum number of stations needed to staff the slaughter floor. Operational administrative requirements, ergonomic factors, special projects and physical layout of the kill floor may affect these numbers. Each site should be evaluated by the operational personnel to determine the appropriate staffing levels needed in each facility.
The ante-mortem inspection is performed by the CFIA personnel under the supervision of the VIC. In certain situations, establishment of a permanent ante-mortem inspection station may be required (e.g. just in time slaughter).

* The term "shared" refers to the fact that both Industry and the CFIA are involved in the process control activity
1 Process monitoring non-stationary position; and
2 Includes the VIC's position.
The HLIS monitor position shall be managed through the use of inspection station rotation. The CFIA inspection personnel shall perform general daily record monitoring, perform correlation tests for presentation standards, finished carcass product standards and Shewhart Control Chart performance as per specified frequencies and generally oversee the activities of the Production and QC departments. It is recommended that the same individual be assigned to the floor monitoring position for at least the full shift and work in conjunction with and under the supervision of the slaughter floor veterinarian.
The figures that are indicated for the various inspection stations may be impacted by various facility configurations with respect to carcass presentation. The VIC may re-distribute the recommended staffing numbers after consulting the Area Red Meat Program Specialist and the RVO provided the total numbers are not altered.
4.2 Random Testing Guideline
One of the major principles in any statistical testing program involving the selection of samples is that each unit in the population should have an equal chance of being selected as a sample. This is not completely possible under HLIS slaughtering conditions. These guidelines are intended to support that principle within the practical restraints of this inspection system.
As a general observation, production employees should be exempted from the testing procedure if they may be in a compromised circumstance with respect to objectivity when conducting these tests. If a production employee is used in performing any test, special efforts should be in place to ensure s/he is not influenced by the presence of the Production Supervisor. It is recommended that the QC Department be in charge of all testing requirements when this situation is encountered. The Veterinarians in Charge shall review this situation in their respective facilities and determine what arrangement is most effective in providing the most reliable product evaluation procedure.
Finished Product Standard (FPS) checks
A designated plant person(s) shall select random times according to the operator's written program for conducting the carcass tests for food safety and non food safety defects. The selected times shall be submitted to the VIC or delegate by the operator before the beginning of each shift.
The operator need only perform the required checks within the 30 minute or 1 hour period required by the program, additional randomness is not required. These test times shall also be submitted to the VIC or delegate by the operator before the start of each shift.
Shewhart Control Chart checks
These shall be performed by the operator on a random basis ensuring that each hour of the production shift is tested. The schedule of times shall be submitted to the VIC or delegate by the operator prior to the start of each shift.
These shall be performed by the operator after all rework tasks have been performed on the detained lot. The entire population of the lot shall have an equal opportunity of being selected for the carcass subgroup test. The CFIA shall be notified when a rework is being performed on a detained lot and records of performance shall be maintained by the operator. Rework testing frequency by the CFIA shall be discretionary.
When the various carcass monitoring tests and evaluations are being performed either by the operator or by the CFIA the general rule of observation is that the proximity of the carcass surface shall be at arm's length and conducted from an acceptable inspection platform as referenced under section 3.0 - Facility Requirements.
CFIA oversight and verification activities
The CFIA shall perform daily periodic oversight monitoring and verification functions with respect to the operator's testing, recording activities as well as employee performance to ensure the satisfactory application of the HLIS program. These activities shall also include randomly scheduled daily correlation tests but may also include unscheduled or spontaneous correlation tests if deemed necessary by the VIC or delegate. Independent verification tests of a particular process control step are not routinely performed by CFIA but at the discretion of the VIC such test(s) may be authorized where it is determined that such a test is warranted.
4.3 CFIA/Accredited Employee Carcass Identification and Trimming Procedures
CFIA held tags are to be used for conditions requiring veterinary disposition (category II TPC) or in special circumstances as deemed necessary by CFIA personnel. In addition, an in-plant identification tag or ink marking system will be used by plant employees to identify dressing defects and Category I TPCs.
In-plant identification tags or ink marks must be removed once the defect is corrected. Defects so identified may be trimmed at any working position down the line or off line at the operator's discretion as long as the defect is removed sanitarily before leaving the final carcass approval area.
CFIA held tags may only be removed by a CFIA inspector or by an accredited plant employee under the direct and immediate supervision of a CFIA inspector.
4.3.1 - Duties of Trained/Accredited Plant Personnel
- Head and tongue preparation and presentation
Head and tongue preparation may vary between establishments (e.g. tongue attached to the head or detached, head oriented up or head oriented down), but once decided must remain consistent within the establishment. The employee shall thoroughly palpate the tongue and mark or signal the CFIA inspector of any abnormalities. The employee shall also incise the lateral and medial muscles of mastication exposing predominantly muscle tissue (at least 75%) and minimum connective tissue (no more than 25%). The medial and lateral retro pharyngeal and mandibular lymph nodes shall be prepared and presented intact and in a consistent location.
- Viscera preparation and presentation
The viscera shall be presented in a consistent orientation that normally provides for minimum manipulation by the CFIA inspector. Under normal operating conditions the operator will provide one or more "presenters" upstream from the CFIA inspection station to ensure that all viscera are properly prepared and oriented.
- Heart: a trained plant employee shall open the heart such that all chambers are exposed and also incise the interventricular septum.
- Kidneys: a trained employee shall open the kidney capsule (minimum 75%), remove them from the carcass and present them on the table in a consistent location for CFIA inspection.
- Stomach/intestines: a trained plant employee shall orient the rumen and its attached components in a consistent orientation as approved by the VIC.
- Carcass defect detectors
The carcass detector will use an approved in-plant marking/tagging system to identify all dressing defects and Category I TPCs and may also place CFIA held tags on certain carcasses at the direction of CFIA Inspection staff.
- Carcass defect trimmers
The carcass trimmer will trim all identified defects on line or off line but no trimming shall be performed on CFIA held carcasses until after veterinary disposition. CFIA held tags are only removed after trimming and at the direction of a CFIA Inspector. The carcass trimmers shall remove all other identification marks/tags after trimming and no carcass shall leave the final carcass approval area until these procedures are completed.
- Process control step monitors
This includes those accredited employees who monitor all presenter activities, perform FPS (FS and OCD rework) carcass monitoring and Shewhart Control Chart monitoring. The monitors shall score, record and initiate corrective actions as required in each of their respective monitoring functions.
When an accredited plant employee is required to perform more than one task, whether an accredited task or non accredited task relating to that person's job, that employee shall not be distracted by additional responsibilities that would prevent him from otherwise satisfactorily performing the accredited functions of the position as if it were his sole responsibility.
5.0 Statistical Process Controls
All slaughtering plants are responsible for producing product that is consistently in compliance with minimum food safety standards as set out in the Meat Inspection Act (MIA) and Meat Inspection Regulations, 1990, (MIR), Meat Hygiene Manual of Procedures (MOP) and the Food Safety Enhancement Program (FSEP). In order to be able to evaluate as well as enhance an operator's ability to comply with these standards, the High Line Speed Inspection System (HLIS) program incorporates the use of Statistical Process Controls (SPC). These are science based tools that help to improve and at the same time objectively measure the performance effectiveness of a manufacturing process.
Under the HLIS, dressed carcasses and their parts must meet several performance criteria during the dressing procedures. These performance criteria are applied in the form of Presentation Standards (PS), Finished Product Standards (FPS) and Shewhart Control Chart performance standards. These tools provide the means for assessing the carcass and parts for food safety and wholesomeness while also determining if the slaughter process is in control. The PS, FPS and Control Chart tests are all tools that are applied at specified locations by randomly sampling and testing the carcass and/or its parts during the production shift for a pre-determined level of manufacturing performance.
5.1 Introduction to Control Charts
This section provides a brief introduction to the use of control charts. For additional detailed information on this as well as Presentation Standards (PS) and Finished Product Standards (FPS) information, please consult relevant CFIA training modules and section 6.0 - Presentation Standards and section 7.0 - Finished Product Standards for Carcasses of this policy.
Control charts are used in various manufacturing environments to provide a statistical indication of how effectively a certain manufacturing step(s) is performing under a prescribed set of Quality Assurance standards. Their importance rests in being statistically reliable in evaluating the manufacturing step they are assessing. For optimal benefit it is critical that this evaluation occurs at a location immediately downstream from the process step that is being evaluated in order to provide real time performance measurement and feed back to the operating step under evaluation.
The Shewhart Control Chart operates on the principle of measuring a process step's departure from mean or average performance through the use of units of standard deviation. This approach has been shown to be an objective statistically reliable means of determining when early process intervention is warranted.
The application of the Shewhart Control Chart provides the additional benefit of allowing the use of ISO special sampling plans for evaluating final carcass performance rather than the conventional General Inspection Level II sampling plan which requires a larger carcass sample size.
Under the evaluation of a process by the application of the Shewhart Control Chart, a trained and accredited plant employee shall conduct scheduled randomized hourly control chart tests on 10 consecutive carcasses immediately after the dehiding and evisceration step and prior to any further alteration or trimming of the carcass. The carcasses will only be scored as "positive" or "negative" for the presence of any distinguishable fecal or ingesta defect related to the dehiding or evisceration steps. All test results are to be recorded on form HLIS 001 - Shewhart Control Chart. The CFIA will periodically monitor operator testing and recording activities during the production shift and will perform a minimum of one correlation test per half shift. See section 1.2 - Product Testing.
- For areas above the point of contact with the hook, any findings will not be scored, however, the operator must have a written protocol for addressing any visible contamination associated with this area at a location downstream from this point of evaluation. The reasoning behind this is to avoid carcasses dropping as a result of aggressive trimming in the hook area.
- The area within the circular cut that will be made to remove the bung is not to be scored. It is this area that is bagged during the bunging process, and therefore need not be scored.
Shewhart Control Chart - Beef Evisceration
5.2 Corrective Actions for Shewhart Control Chart Deviations
As previously noted, the Shewhart Control Chart evaluates a process on the principle of units of standard deviation from the mean or average performance. One standard deviation (+/-) from average performance is considered to be acceptable or satisfactory performance. Two standard deviations are considered fair performance and 3 or more standard deviations are viewed as unsatisfactory performance. See Appendix A - Decision Tree for Shewhart Control Chart.
Satisfactory performance: the green zone
No action required.
Fair performance: the yellow zone
Random testing shall be immediately suspended and the operator shall initiate immediate corrective actions as detailed in its written program. Corrective action procedures shall have been previously approved by the VIC or delegate with consultation from the RVO, if necessary. Any new corrective action procedures shall be approved by the VIC or delegate with consultation from the RVO if necessary before implementation. Once corrective measures have been implemented the operator shall perform a retest no earlier than 15 minutes after the previously failed test. Two consecutive satisfactory test scores taken at least 15 minutes apart shall be achieved before random testing is resumed. If the retest score remains in the fair performance zone after any of the 2 consecutive retests the floor supervisor and the VIC or delegate shall consult on the next course of action which shall include a line speed reduction.
Unsatisfactory performance: the red zone
Upon scoring an unsatisfactory test result random testing shall be suspended and an immediate 10% line speed reduction shall be initiated by the operator along with the corrective measures as approved and detailed in the operator's written program. These corrective measures shall have been previously approved by the VIC in consultation with the Area Red Meat Program Specialist/RVO, as required. The CFIA shall be notified immediately whenever an unsatisfactory score is recorded. Once corrective measures have been satisfactorily implemented a retest shall be performed by the operator no earlier than 15 minutes after the previously failed test. The operator shall first achieve a satisfactory score on the initial retest before line speed increases may commence. When 2 consecutive satisfactory retest scores have been achieved and the line speed has returned to normal random testing frequencies shall be resumed.
In the event of a second consecutive unsatisfactory retest score a further 10% line speed reduction shall occur with re-evaluation of the corrective measures and consultation between the VIC or delegate and floor supervisor. Upon completion of each consecutive satisfactory 15 minutes retest thereafter the line speed may be increased by the same increment it was reduced until original line speed is re-established. Also see section 1.2 - Product Testing and Appendix A - Decision Tree for Shewhart Control Chart.
The corrective actions outlined in Appendix A - Decision Tree for Shewhart Control Chart are the minimum actions required at the entry level of the program. Based on individual plant performance the corrective actions decision tree may be modified to reflect an operator's improved data performance profile wherein a line speed reduction would not occur until 2 consecutive red zone failures had occurred (or some similar modification). These changes shall be approved by the Area Red Meat Program Specialist with consultation of the National Red Meat Program Specialist based on supporting establishment data.
6.0 Presentation Standards
The provision for uniform presentation standards is a key element in the implementation of HLIS. It provides not only consistency in presentation of the carcass and its parts but also reduces potential food safety concerns and offers early indication as to whether certain carcass dressing procedures are in control.
Uniform presentation is essential in maintaining inspection efficiency and is critical at the higher rates of slaughter. When the carcass or its parts are not uniformly presented in a predetermined manner, time allotted for inspection must be used to correct or compensate for presentation errors. Therefore, the presentation standards must be met to ensure the effectiveness and efficiency of inspection when the HLIS standards are used. The adequacy of presentation is affected by several factors such as disease conditions, carcass uniformity, evisceration line configuration, sequence of evisceration procedures, adequate equipment, lighting, but most notably well trained and efficient production employees.
6.1 General Responsibilities
6.1.1 Operator Responsibility
Plant management is responsible for implementing the prescribed presentation standards as well as initiating all corrective actions. The operator shall ensure the proper presentation of heads, viscera and carcasses using trained accredited personnel. The operator shall also designate responsible persons to schedule and conduct monitoring tests and take corrective action whenever the required standards are not met. This function is normally shared between Production and QC but may be performed by the QC Department alone if the operator so chooses. The VIC or delegate shall be informed whenever corrective actions are initiated. See Table 6.1.
6.1.2 CFIA Inspection Responsibility
Inspection personnel will monitor the activities of plant employees assigned to perform presentation monitoring checks. This will include evaluations of records, observation of employee performance and correlation tests for comparison with operator's results.
6.2 Presentation Standards
6.2.1 Head Presentation
Tongue presentation may vary between establishments (e.g. tongue attached to the head or detached), but must be consistent within an individual establishment. Prior to the inspector's examination of the tongue, an establishment employee is required to thoroughly palpate each tongue and notify the inspector if abnormalities were found. As this process happens prior to the beef head presentation station, it is expected that when the individual performs head presentation monitoring, he will observe the designated plant employee performing palpation of the tongue on the same number of heads as are evaluated during this test period at the beef head presentation station. In this case, this individual performing the monitoring does not necessarily need to observe the same heads as those evaluated at the head station. Notification to the inspector may be accomplished by directly signalling or by means of a marking system developed by the operator and acceptable to the Veterinarian in Charge (e.g. ink, tags, cuts or other markings). There shall be no visible contamination from ingesta and there shall be no movement or sway of the tongue that would interfere or impede inspection activities.
The parotid lymph nodes may be presented in their natural location or cut free along with their accompanying parotid salivary gland during the process of incising the masseter muscles and be presented attached to the lowest portion of the incised masseter muscle. The presentation must be consistent at one location or the other. The medial and lateral retro pharyngeal and mandibular lymph nodes must be presented intact and in a consistent location. No more than 50% of any lymph node shall be missing.
The head may be presented nostrils facing upwards or downwards but must be consistent. The head must be properly identified to correlate with the viscera and carcass of the same animal. Prior to the inspector's examination of the head, a plant employee is required correctly trim and dress the head, incise both lateral and medial muscles of mastication (cheeks) to expose the muscles for inspection. These incisions are to be made between the muscle planes so that the lateral and medial muscles of mastication are exposed showing predominantly muscle tissue (at least 75%) and minimum connective tissue (no more than 25%), and with no more than 25% of the muscle surface obscured by blood. The head shall not be approved if it bears visible contamination from ingesta. It shall be the operator's responsibility to ensure all heads are properly presented for CFIA inspection. Heads which are improperly prepared or display food safety dressing defects shall be so identified and controlled as inedible material by the operator.
The seepage of blood onto the exposed muscle surfaces may be reduced by cutting the blood vessels (common carotid artery and the external maxillary vein) at the angle of the mandible. Cutting these vessels before the head enters the final head wash cabinet reduces the amount of blood found on the cheeks at inspection.
6.2.2 Viscera Presentation
No red offal (heart, lungs, liver, kidneys) shall be approved for edible use if visible food safety defects are present.
A plant employee shall open all chambers of the heart and incise the interventricular septum to fully expose the interior of the heart for examination for CFIA inspection. Lungs shall be presented in a consistent orientation.
A plant employee shall open the kidney capsule (a minimum of 75% of each kidney shall be exposed), separate the kidneys from the carcass and present the kidneys for inspection with the viscera.
Small and large intestines shall be presented in a consistent orientation with the mesenteric chain fully exposed.
Spleens must be presented in full view of the viscera/carcass inspector in those establishments that do not separate spleen from the viscera.
In each establishment the exact required placement of the various organs on the table is to be determined through consultation with the operator and approved by the VIC (with the assistance of the Area Red Meat Program Specialist and the RVO, if needed). Schematic drawings of the approved viscera placement will be available in the CFIA inspection office and in the establishment, where they can be readily accessed by inspection and production personnel.
There shall be no co-mingling or common contact of viscera units belonging to different carcasses. Overlapping or obscuring of viscera from the same carcass due to improper placement and orientation shall also be prevented. The viscera must be properly identified to correlate with the head and carcass of the same animal.
No part shall be pinched, overhang the table edges or be dragged along.
6.2.3 Carcass Presentation
The operator shall present the dressed carcass for inspection in a manner that will ensure good visualization of the external surfaces, thoracic and abdominal cavities, and cut surfaces of the carcass with the hocks spread apart on 1.8 metres (6 ft) minimum centers. There shall be no movement of the carcass. No organ remnant shall be left in the carcass that obstruct inspection (See appropriate CFIA training modules and form HLIS 004C - ISO SPC Test - Beef Carcass Presentation). Those carcasses that cannot be properly eviscerated as the result of pathological (physiological or disease origin) complications shall not be scored. Additional carcasses shall be chosen for testing if pathological complications have impeded proper evisceration. The carcass must be properly identified to correlate with the head and viscera of the same animal.
6.3 Testing and Scoring Presentation Standards
6.3.1 Test Procedures for Presentation Standards
The presentation tests will be made at the following frequencies. Also refer to section 6.1.1 - Operator Responsibility.
|Party performing sampling||Sampling Mode||Frequency based on lot size (carcasses per hour-CPH)|
|Operator||Normal||< 200 CPH 60 min., ≥ 200 CPH 30 min.|
|Operator||Reduced||< 200 CPH 60 min., ≥ 200 CPH 30 min.|
|Operator||Tightened||< 200 CPH 30 min., ≥ 200 CPH 15 min.|
|CFIA||Correlation Test||The CFIA shall perform one randomly scheduled correlation test per half shift unless otherwise determined by the VIC or delegate. See section 1.2 - Product Testing|
The CFIA will perform correlation tests in accordance with Table 6.1. The CFIA will also perform periodic record monitoring activities to evaluate the entries made on presentation forms by establishment personnel. The frequency for such evaluations will be established by the VIC. The inspector shall enter the date, time, and his initials at the bottom of each form evaluated, and if errors are found on the forms or they are not complete or timely, the inspector should describe the findings and actions taken on the bottom or back of the form. The CFIA correlation test may also be recorded on the operator's form and will use a different colour of ink to distinguish CFIA information. Records of presentation tests shall be maintained for a period of one year.
Line speed checks
An accurate digital line speed indicator(s) for both the head chain and the carcass chain is required at a location readily accessible to the person performing presentation tests. A 1% margin of error shall be allowed for inherent variations in the system.
6.3.2 Scoring Presentation Errors
Only the first error observed for each sample will be scored on the test for each of the following:
Presentation Error Categories
- Tongue (if presented separately, may be hung by the tip or root but is scored as part of head presentation):
- visible gastro-intestinal tract (GIT) contamination present;
- improper orientation, turned > 45 degrees from center position (hung backwards, sideways);
- visual mass(es) present; palpation does not take place;
- loss of identification;
- part or > 50% of the tongue missing.
- Head (may be suspended with head pointing up or down, tongue in or out)
- visible GIT contamination present;
- improper dressing (hide, eyelids, horns, lips, loose hairs);
- improper preparation of head (< 75% cheek muscles exposed/incised, a minimal ratio exposed cheek muscle tissue to connective tissue of 3 for 1, > 25% blood obscuring surface, muscles not incised, tongue not palpated/lesion undetected);
- loss of identification;
- part or > 50% of any lymph node/tongue/medial/lateral masticator muscle missing.
- Tongue (if presented separately, may be hung by the tip or root but is scored as part of head presentation):
- Viscera (all viscera are scored collectively under this heading)
- visible GIT contamination present;
- improper position/orientation; incorrect schematic position, turned more than 45 degrees from normal center position;
- improper preparation; heart not adequately opened, >25% surface obscured;
- loss of identification, co-mingling or common contact with other carcass parts;
- part or >50% of organ missing.
- visible GIT contamination present;
- improper position/orientation; incorrect schematic position, turned more than 45 degrees from normal center position, upside down, etc.;
- loss of identification, co-mingling, common contact with other carcass parts;
- part or > 50% of liver/gall bladder/lymph node missing.
- Gastro-intestinal tract (GIT)
- GIT internal spillage impeding inspection activities (inspector becomes contaminated, wash up, requires longer to perform duties, etc.);
- improper position/orientation; incorrect schematic position, turned more than 45 degrees from normal center position;
- loss of identification, co-mingling or common contact with other carcass parts;
- part or > 50% of any organ/lymph node missing;
- GIT table overhang, dragging, pinching.
- visible GIT contamination present;
- improper preparation; > 25% of at least one kidney is covered by capsule;
- loss of identification, co-mingling, common contact with other carcass parts;
- part or >50% of at least one kidney is missing.
- visible GIT contamination present;
- loss of identification, co-mingling or common contact with other carcass parts;
- part or > 50% of any organ/lymph node missing.
- generalized GIT contamination preventing inspection of carcass;
- improper orientation/position; hind legs not spread to specified distance for correct carcass exposure;
- improper dressing of carcass, organ remnant, unremoved parts preventing final inspection;
- loss of identification.
6.4 Corrective Actions for Failed Presentation Tests
Presentation checks shall be performed using ISO 2859-1 sample plan and the ISO switching rules between Reduced mode, Normal mode and Tightened mode shall apply. Sample size is based on the operator's production volume. All new facilities shall commence testing in Normal mode. The results and follow up actions of all presentation tests are recorded on form HLIS 004 A, form HLIS 004 B or form HLIS 004 C for head, viscera or carcass presentation tests. All corrective actions generated by presentation checks will be the operator's responsibility and may be initiated by either Plant Production or Quality Control. Under normal circumstances Plant Production and QC shall manage their respective corrective action issues separately unless otherwise defined in the operator's written program. If the CFIA's presentation correlation test result fails to correlate with that of the Presentation Monitor an immediate retest shall be performed and QC will be notified. Two consecutive non matching correlation tests between the operator and CFIA will require that corrective actions be initiated by the operator based on the results of the second CFIA test which shall be taken as the correct score. The CFIA will monitor all Plant Production and QC corrective action activities to ensure program requirements are met. The discrepancy in scoring results shall be investigated and reconciled in consultation with the VIC after all required corrective actions have been implemented*. Also see section 1.2 - Product Testing.
There shall be no more than one process control step (Shewhart or Presentation test) under a line speed reduction at any given time. If a failure is discovered at any other presentation test site, while a line speed reduction is already in effect, the line speed is not reduced as a result of this second failure. Random testing is, however, suspended at this newly discovered failure site and 15 minute retests are initiated. Random testing will resume (as per Appendix A - Decision Tree for Shewhart Control Chart) at each site as it is brought under control. Line speed increases will only take place, however, as the last site to be brought into compliance is being brought under control. All corrective actions shall be recorded on the testing form or a document attach to the form stating the corrective actions.
During scoring, numerous defects can be observed on a sample unit, however only one attribute/defect is scored per sample unit. For a correlation test to be completed, the same sample units should be failed by the CFIA monitor and establishment monitor. As an example, during a normal mode test of viscera presentation, the CFIA monitor may fail sample units 2 and 3. The establishment monitor may also fail sample units 2 and 3 but for different defects. This test correlates as the same sample units (2 and 3) were failed by both the monitor and CFIA. Conversely, if the sample units which failed were not the same then a retest is indicated, and shall be completed immediately. The goal is to have establishment personnel demonstrate they can identify the same deficiencies as CFIA personnel.
The operator must continue to successfully pass 4 out of 5 consecutive random tests to maintain Normal mode status. Should the operator fail 2 presentation tests within any window of 5 consecutive tests in Normal mode, the testing mode shall be switched to Tightened, no other corrective action shall be initiated.
Upon entering Tightened mode random testing shall be suspended and a presentation retest shall be conducted every 15 or 30 minutes until Normal mode is restored (5 passed tests). Once returned to Normal mode random testing shall be resumed. When returning to random testing in Normal mode, testing should be resumed at the established frequency already submitted as long as the next test time falls within the next hour of production. If not, another test must be randomly selected within the next hour of production.
After any 2 consecutive failures in Tightened mode the VIC or delegate shall be notified and consultation between the operator and the CFIA shall take place to determine the cause of the presentation under performance. At the discretion of the VIC a 10% line speed reduction may be exercised if immediate improvement cannot be achieved in the subsequent retest score.
Ten consecutive successful test scores in Normal mode shall be achieved before switching may occur to Reduced Mode. Any single failure of a test score in Reduced mode will move the operator back to Normal mode. No other corrective actions shall be initiated.
Excessive line speed
If on any test the line speed is found to exceed the currently allowed rate as per Table 4.1A and Table 4.1B an immediate line speed reduction to the allowed rate is required. After any line speed reduction, the line speed shall be rechecked after 15 minutes. If the line speed is above the currently allowed rate after the retest the VIC or delegate must be notified and a 10% reduction from the current maximum allowed line speed will apply.
|Sample Code||AQL||Normal Frequency||Tightened Frequency||Reduced Frequency|

7.0 Finished Product Standards for Carcasses
It is critical in slaughter production environments to be able to perform periodic product evaluations on the finished product in order to validate effective hygienic manufacturing performance. Finished product standards (FPS) are one of several tools designed to ensure that the procedures used in preparing and approving a dressed food animal carcass are in control and are producing a product that is in conformance with Canadian regulatory standards. These evaluations are performed on randomly selected sets of carcasses/products selected throughout the production shift to validate the operator's food safety and hygienic performance.
The establishment's Production personnel, QC personnel, and the CFIA's inspection staff each have a role to fulfill in applying the finished product standards. These responsibilities vary depending on the status of the process. In general, designated establishment personnel (Production or QC) are responsible for performing finished product standards tests as well as taking the appropriate action in response to the results of those tests. Designated CFIA inspectors are responsible for monitoring operator tests and actions, performing correlation tests and performing periodic independent tests to verify the company's performance as deemed necessary by the VIC. The VIC or designated qualified CFIA personnel shall perform all tests/evaluations related to carcass FPS for food safety.
The CFIA reserves the right to take regulatory corrective action including retention of product when it is determined by the VIC or delegate that the operator has failed to properly and reasonably apply the HLIS program.
The approved carcass population is evaluated for 2 general categories of defects:
- Food safety (FS) defects which include identifiable fecal material, identifiable ingesta material and food safety pathological conditions. FS defects shall be evaluated on the basis of colour, texture and consistency and must be clearly identifiable before being scored as such. Generally defects that are <3.0 mm in their greatest dimension can be difficult to characterize with certainty when using only the naked eye. If the observer is not able to clearly identify a defect as being of FS origin it shall be classified as extraneous or foreign material and scored under the Other Carcass Defects (OCD) category.
- Other Carcass Defects (OCD) are regarded as unsuitable for consumption and/or fail to meet regulatory requirements but do not pose a direct food safety risk.
These 2 general categories of defects are evaluated on randomly selected sample sets of approved carcasses collected on the slaughter line at a point after all trimming is completed. In certain circumstances and with the approval of the VIC in consultation with the Area/National Red Meat Program Specialists and the RVO, the sample evaluation may be performed on line provided satisfactory trial evaluation of this procedure has been conducted.
Each of the 2 general categories of defects noted above contain 2 specific types of defects:
- Manufacturing/Dressing Defects (MDs)
These are defects that occur during transportation, live handling, stunning and dressing procedures and are to be distinguished from pathological defects or lesions referred to as Trimmable Pathological Conditions (TPCs). Refer to Table 7.1.
- Designated Trimmable Pathological Conditions (TPCs)
Under the HLIS system the operator has full responsibility for the identification and removal of dressing/manufacturing and specified pathological defects as well as the removal of all designated trimmable pathological conditions. These trimmable pathological conditions fall into one of 2 categories identified as Category I or Category II TPCs (see Table 7.1). Category I TPCs are to be identified and removed by plant personnel on or off line and do not necessarily require direct CFIA supervision. Category II TPCs may also be removed on or off line by plant personnel but only after first being identified by CFIA inspectors. Any Category II food safety TPC encountered in a sample set scores as zero tolerance and will require sanitary removal of the defect and may result in the failure of the carcass sample set. Refer to Appendix C - Decision Tree for Finished Product Standards - Carcasses with Food Safety (FS) Defects to determine next steps i.e. status of the associated lot and test mode status (Reduced, normal or tightened mode).
7.1 Trimmable Pathological Conditions - TPCs
- Category I TPCs are simple isolated resolved pathological or unacceptable anatomical conditions sometimes associated with dressing procedures but which do not affect the disposition of the entire carcass and are assigned to the industry accredited detectors and trimmers for identification and removal. TPCs include and are limited to bruising >2.5 cm, simple fractures, dry adhesions >5.0 cm and single tarsal arthritis.
- Category II TPCs includes all other pathologies and these must first be identified by CFIA personnel and then trimmed by an accredited trimmer on or off line under CFIA supervision. The presence of a Category II TPC in any sample set will require correction for the condition prior to the carcass(es) being released followed by the appropriate corrective action for the lot if applicable.
The normal CFIA procedure for Category II TPCs shall be:
- The head inspection station, if applicable, will place an alert tag/equivalent marking system for further evaluation by viscera/carcass inspectors.
- Viscera/carcass inspector will further evaluate and either direct a designated employee to place a held tag for veterinary disposition, or will allow carcass to continue with alert tag in place.
- If the carcass is tagged held it is retained for Veterinary inspection. If not retained the carcass continues on line with the alert tag in place for removal of condition on line or on the re-trim rail by an accredited trimmer.
|Identified and trimmed by the operator (category I TPCs)||Identified by the CFIA and trimmed by the operator (Category II TPCs)|
|All dry adhesions/scar tissue >5.0 cm||All other pathologies|
|Simple fractures||All other pathologies|
|All bruising >2.5 cm unless humane handling and transportation implications||All other pathologies|
|Single Tarsal Arthritis||All other pathologies|
7.2 Carcass Evaluation for Defects
7.2.1 Carcass evaluation for food safety (FS) defects
The carcass is evaluated for the presence of fecal, ingesta and food safety pathology defects based on ISO sampling plan 2859-1, S-1. The failure of a lot due to Category II TPCs being detected is to be handled in the same way as any other failure, however the detection of these conditions is the responsibility of the CFIA and these incidences should be discussed with the VIC to be rectified. The lot size shall be the choice of the facility operator (see definitions) and agreed to by the VIC/Area Red Meat Program Specialist but must remain within the operator's process control capability. Also included in this plan are associated switching rules which allows the operator to function in Normal, Tightened or Reduced sampling mode based on test performance results. ISO switching rules apply. Scheduled random sampling is performed by the facility operator and monitored by the CFIA. Refer Appendix C - Decision Tree for Finished Product Standards - Carcasses with Food Safety (FS) Defects. Once a lot size category is selected by the operator it may not be switched spontaneously. A written request shall be submitted to the VIC and a mutually acceptable implementation date negotiated.
All carcass samples shall be selected at one time (consecutively) if the sample will be examined off line. When selecting carcasses from a moving line, random selection principles are applied. Sample size is determined according to the operator's ISO status under ISO sampling plan 2859-1, S-1 (this sample plan is only applicable if the Shewhart Control Chart is applied at the evisceration step). Record all non-conformances on form HLIS 003 - Finished Product Standards - Carcasses with Food Safety (FS) Defects.
After performing a CFIA correlation test, the inspector shall compare the test score with the operator's results. If results are not in agreement an additional correlation test shall be performed. In the event of a second non matching score CFIA test results shall be officially recorded as the correct result and appropriate corrective actions initiated (if applicable) by the operator.
When the test is performed by the CFIA and the same form for recording results is shared with the operator a different ink colour shall be used to distinguish the CFIA results.
Normal mode is maintained as long as the operator continues to pass at least 4 out of 5 consecutive carcass sample set tests. In each carcass sample set the carcasses are examined for food safety defects only. All carcasses shall be examined for food safety defects irrespective of how many defects are observed. Observation of one or more food safety defects will fail the sample set but not necessarily alter the classification of Normal test mode unless this is the second failure within 5 consecutive tests. See section 7.2.2 - Corrective Actions for Food Safety Defects.
The operator has the option of performing retests every 15 or 30 minutes as this frequency directly affects the size of the lot to be reworked. Tightened mode is maintained until the operator has passed 5 consecutive satisfactory tests. In each carcass sample set the carcasses are examined for food safety defects only and all carcasses in the set shall be examined irrespective of how many food safety defects are noted. Five consecutive satisfactory sample sets must be achieved before returning to Normal Mode. See section 7.2.2 - Corrective Actions for Food Safety Defects.
Reduced mode is an elective category and the operator may decline if he so chooses and is achieved after 10 consecutive satisfactory tests in Normal mode. The operator must perform without any defects being observed in any carcass sample sets while in Reduced mode or he shall return to Normal mode. All carcasses in the sample set shall be examined for food safety defects irrespective of the number of defects found. See section 7.2.2 - Corrective Actions for Food Safety Defects.
7.2.2 Corrective Actions for Food Safety Defects
FS action limits - single site gastro-intestinal tract (GIT) defect
Carcasses in a stationary sample set which exhibit no more than 1 defect per carcass ≤5 mm in its greatest dimension and originating from the GIT shall not be scored. However, it should be recorded on the appropriate section of form HLIS 003 - Finished Product Standards - Carcasses with Food Safety (FS) Defects. The defects shall be removed sanitarily before the carcasses are released. Any carcasses displaying more than one such defect, irrespective of size, or one or more defects of another FS category shall be scored in accordance with the HLIS Program requirements and all corrective actions will apply. This action limit exemption does not apply to any carcasses that are evaluated and scored while on a moving carcass line.
Under normal mode a lot failure occurs whenever there is a failure of more than 1 out of 5 consecutive carcass sample sets. When this occurs only the current production lot shall be detained and reworked for any FS defects that caused the lot failure. The operator shall then move into Tightened testing mode on the next sample test.
The switch to the Tightened mode results in the suspension of random sampling with retests being performed every 15 or 30 minutes as per operator's written program. Under tightened mode 5 consecutive sample sets must pass to return to Normal mode. The failed lot that cause entry into Tightened mode shall be detained and reworked as above. While in Tightened mode any test failure requires rework of the affected lot. See section 7.4 - Rework of Failed Lot(s).
A lot failure occurs in this mode upon the first failed test of a sample set and the associated lot is identified for rework. A reduction in status to Normal mode also occurs at the next scheduled test.
Any defects noted during the evaluation shall be sanitarily removed before the carcass is released. Particulate material <3.0 mm in size that cannot be clearly or readily identified as GIT contamination using the normal criteria of texture, colour and appearance will be treated as extraneous material and must be sanitarily removed.
The acceptable quality level (AQL) for carcass food safety defects for sample code letter 'B' is 6.5. The acceptance and rejection numbers for ISO SPC test are shown in Table 7.1A.
|AQL||Sample Code S-1 Lot size||Sample Mode||Sample Size||Accept||Reject|
7.2.3 Carcass Evaluation for Other Carcass Defects (OCD)
The carcass is evaluated for other carcass defects (OCD) which are defects that do not pose a direct food safety concern such as bruises, fractures, adhesions, hair, failed regulatory requirements (e.g. presence of non-lactating mammary tissue, untrimmed stick wound, etc.). When testing for these criteria generally about 1% of the carcass population is randomly sampled by the operator and monitored by the CFIA. The carcass sample size shall be determined by the VIC and Area Red Meat Program Specialist based on the above criteria. Refer to Appendix B - Decision Tree for Finished Product Standards - Carcasses with Other Carcass Defects (OCD). Reduced testing frequencies may occur in this category based upon operator's performance.
The operator shall perform carcass tests for other carcass defects on each production lot during each production shift. The choice of frequency will be correlated to the operator's defined lot size (1.0 hour of production or 0.5 hour of production). See Table 7.2. These tests shall be performed on a random basis and may be conducted at the same time as the food safety defect test.
After ten (10) consecutive successful test scores the operator may elect to move into Relaxed testing mode. The same number of carcasses shall be tested but at a lowered frequency. See Table 7.2. Any test failure will return the operator to Regular mode.
When taking samples all carcasses shall be selected at one time if the sample is to be examined off line. When selecting carcasses from a moving line, random selection principles shall be used and consecutive sample units shall be collected. The non-conformance results for the sample units are to be recorded and scored on form HLIS 002 - Finished Product Standards - Carcasses with Other Carcass Defects (OCD).
When the test is performed by the CFIA and the same form is shared with the operator a different ink colour shall be used to distinguish the CFIA results.
After performing a CFIA correlation test the inspector shall compare the test score with the operator's results. If results are not in agreement an additional correlation test shall be performed. In the event of a second non matching score the CFIA test results shall be officially recorded as the correct result and appropriate corrective actions initiated (if applicable) by the operator. Discrepancies between test results can be discussed with CFIA officials.
The VIC and the operator shall collaborate to determine the reason for the non correlation. The CFIA inspector shall also evaluate appropriate operator's records for timeliness, completeness, and accuracy at the preselected random times and correlate the results with the appropriate establishment representative.
7.2.4 Corrective Actions for Other Carcass Defects
Upon failing any FPS test for other carcass defects (OCD) whether in Regular or Relaxed mode the operator shall immediately identify and hold for rework only the immediate production lot associated with the test failure. If the operator was in Relaxed testing mode he shall return to Regular testing mode. Ten (10) consecutive successful test scores shall be achieved before returning to Relaxed mode. The affected lot shall be reworked for the defect(s) that were identified in the failed test score.
7.2.5 CFIA/Operator Testing Frequency
All correlation checks performed by the CFIA monitor will be selected on a random time basis. More than one check per shift or half shift may be performed if there is concern regarding test results. The VIC or delegate shall approve any additional testing.
|Finished Product Standards||Carcass testing frequency|
|CFIA - FS and OCDs||once per half shift + spontaneous as required per VIC. See section 1.2 - Product Testing.|
|Facility Operator FS||once per hour R & N/once per 15 or 30 minutes T|
|Facility Operator OCDs||once per hour Rg, once per 2 hours Rx|
R = reduced, N = normal, T = tightened, Rg = regular, Rx = relaxed
7.3 Scoring Carcass Defects
7.3.1 Food safety (FS) Defects
The following defects have a zero tolerance. For those defects that may be questionable as to origin and are < 3.0 mm in their greatest dimension please refer to section 7.0 - Finished Product Standards for Carcasses for Additional Criteria.
- identifiable fecal material
- identifiable ingested material
- spinal cord remnant(s) in OTM carcasses
- food safety pathology (any lactation spillage shall be sanitarily removed by a trained employee prior to the pre-evisceration wash)
All food safety defects that are observed while examining a sample set shall be sanitarily removed before the sample set is released. All findings shall be recorded on form HLIS 003 - Finished Product Standards - Carcasses with Food Safety (FS) Defects. Refer to Appendix C - Decision Tree for Finished Product Standards - Carcasses with Food Safety (FS) Defects.
7.3.2 Other carcass defects (OCD)
Summary is shown in Table 7.3.

- Accept a lot with total of 6.9 or less and reject with a total score of 7 or greater.
- If what is found is less than the minimum minor size or count listed, do not score.
- Where minor defects are numerous enough to classify as a major, do not score as minor also.
*GD = greatest dimension
7.4 Rework of Failed Lot(s)
- Operator responsibilities and actions
Specific lots of product retained for rework may, at the discretion of the Operator, be reworked as the original lot(s) or be subdivided into smaller lots of carcasses. Once the specified lot has been reworked for the appropriate defects one standard sample set of 3 carcasses will be randomly selected for each 100 carcass lot reworked. A lot of less than 100 carcasses shall have a minimum sample size of 3 carcasses with a minimum lot size of 25. Lots exceeding 100 carcasses shall have their sample numbers prorated according to their lot size (e.g. 150 carcasses would require a minimum of 4 carcasses, 175 would require 5 carcasses, 200 would require 6 carcasses etc.). Samples of reworked product that are presented for re-inspection must be randomly selected from the lot's declared population. Refer to Appendix E - Decision Tree for Carcass Rework.
The operator shall randomly select a sample set from throughout the lot as per testing criteria listed in form HLIS 002 - Finished Product Standards - Carcasses with Other Carcass Defects (OCD) and/or form HLIS 003 - Finished Product Standards - Carcasses with Food Safety (FS) Defects and achieve a satisfactory test result before releasing it for further processing. If the lot was detained for rework because of a FS defect, the sample set shall be examined for those FS defects only (any other encountered defect, FS or OCD, shall be sanitarily removed). The lot shall be released if no FS defects are found in any of the sample units. The lot shall be detained and reworked again if any of the FS defect(s) that failed the lot are found.
If the lot was detained for rework for other carcass defects (OCD), the lot shall be examined and corrected for the specific non-conformance(s) which initiated the process control action. Once the lot is reworked it shall be sampled and evaluated as described above and released or reworked in accordance with the sample findings.
The CFIA shall be informed whenever rework on a lot is necessary so that they can periodically monitor the rework procedures.
- CFIA responsibilities and actions:
- Rework testing frequency by the CFIA shall be discretionary. The CFIA will periodically monitor the rework procedures to ensure that the Operator is meeting the requirements of the program.
- The VIC or delegate shall be informed whenever corrective actions are taken on a failed rework lot.
7.4.1 Voluntary Rework Under Extraordinary Circumstances
Due to extraordinary circumstances beyond the operator's immediate control certain groups of carcasses may be presented with conditions on the evisceration floor that significantly bias that group towards failure of the performance standards for Finished Product Testing. In such circumstances and at the discretion of the VIC, the operator may request that such a group of affected carcasses be exempted from FPS Testing provided that the operator agrees to properly identify and retain the affected group for rework as described in section 7.4 - Rework of Failed Lot(s), the exempted group of carcasses poses no food safety concerns and an approved written procedure has been established for the handling of such carcasses in the operator's written program and/or HACCP plan.
