Decision Tree for Hazard Analysis Critical Control Point-based Inspection Program Evisceration Performance Test. Description follows.

Description of the Decision Tree for HIP Evisceration Performance Test

Under the Hazard Analysis Critical Control Point based slaughter inspection program for swine, dressed carcasses and their relevant portions must meet several performance criteria during the dressing process. These performance criteria (also referred to as standards) are measured at strategic locations in the dressing/inspection process using evisceration performance testing (bunging/viscera removal), Presentation Standards (abbreviated to "Presentation") testing, and Finished Product Standards testing.

This appendix provides a visual description of the policy on hazard analysis and critical control point based slaughter inspection program for swine evisceration performance testing as detailed in section 5 of Annex C, Chapter 17.

This decision tree consists of five boxes.

Box number one (1) – normal mode

  1. Continue random testing in normal mode unless one of the following occurs:
  2. If this is the tenth consecutive passed test, switch to the reduced mode (box number 2).
  3. If this is the second rejected test in the last 5 tests, implement corrective actions, notify the Canadian Food Inspection Agency and switch to tightened mode (box number 3). Increase finished product standards – food safety category 1 test frequency (for details see section 5.2.3)
  4. A failed test for small plants must be followed by another test in half an hour.

Box number two (2) – reduced mode (elective)

Continue in reduced mode as long as there are no failures.

  1. When a failure occurs, take corrective actions as deemed necessary, return to normal mode (box number 1). Suspend finished product standards – food safety category 1 and random evisceration testing. Perform 2 follow-up evisceration tests, the first within 15 minutes and the second 15 minutes later (half an hour for small plants). A finished product standards – food safety category 1 test shall be performed immediately after each of the two evisceration tests (as per section 5.2.3).
  2. When 2 consecutive evisceration tests pass, return to random testing in normal mode for evisceration. Resume random finished product standards – food safety category 1 testing provided finished product standards – food safety category 1 test has passed. Any failure of finished product standards – food safety category 1 see Appendix C.
  3. If any of the 2 evisceration tests fail, repeat the procedure described in A.

Box number three (3) – tightened mode

  1. Suspend random testing and implement corrective action(s) and retest within 15 minutes. Thereafter, retest every 15 minutes. Increase finished product standards – food safety category 1 test frequency as per section 5.2.4.
  2. If first test and next subsequent 4 tests pass, return to box number 1.
  3. If this is the second rejected test in a window of 5 tests while in Box number 3 go to box number 4.

Box number four (4) – tightened mode (continued)

  1. Notify veterinarian in charge (or delegate), reduce the line speed by 10%, initiate corrective action(s) and test in 15 minutes. Continue increased finished product standards – food safety category 1 test frequency.
  2. If the subsequent test is passed, increase line speed 10%. If the next subsequent 4 tests pass, return to box number 1.
  3. Any failure while in Box number 4 go to box number 5.

Box number five (5) – tightened mode (continued)

  1. The operation is deemed to be in questionable control. Consultation with the veterinarian in charge (or delegate) will determine if there will be a temporary stop of operations. An effective action plan shall be implemented. An additional 10% line speed reduction shall be applied.
  2. Increase line speed 10% for each passed test until normal line speed is obtained and return to box number 1 after 5 successful consecutive test results.
  3. Any test failure notify the veterinarian in charge.
