The viscera shall be consistently presented to meet the operator's presentation standard and to minimize manipulation by the CFIA inspector. Viscera (grey offal and red offal) may be presented in several configurations. Each operator will determine in conjunction with the VIC which method of viscera presentation and orientation will be implemented in the establishment.

All operators, regardless of the line speed in their plant, will create a diagram depicting the reference standard for viscera presentation in their establishment and, after VIC approval, this schematic will serve as the scoring standard for the ISO viscera presentation tests.

8.1 Red Offal

Note

Where portions of paired organs (e.g. kidneys) are missing, at least 50% of each of the paired organs or one complete organ from the pair shall be present to allow the Inspector to render a disposition. At least 50% of an unpaired organ (e.g. heart) shall be present in order for a disposition to be rendered. In the case of the liver, at least 50% of the liver shall be present.

Where an organ such as the lungs, liver or kidneys are presented with no part of the organ missing it is sufficient to only examine the exposed side of the organ without further manipulation. Failing this the Inspector shall proceed to manipulate the portion to the extent that these conditions are met.

8.1.1 Red Offal Presentation – Hook

The red offal must be readily accessible and consistently suspended as determined by the operator's standards for presentation. Intact organs (defined for the purpose of HIP viscera presentation testing as the heart, liver and lungs) must be present, the pericardial sac must be incised and there must be no gastrointestinal tract (GIT) contamination of the tissues. The red offal shall be close enough to allow easy manipulation by the inspector, if necessary, but not so close so as to impede the inspector's view of the grey offal.

Red offal hook presentation generally includes the larynx (tongue may or may not be attached), trachea, esophagus, lungs, heart and liver. The offal may be suspended from the hook by the posterior base of the larynx, proximal trachea, or base of the heart. Placement is critical to present the correct travelling surface of the red offal for inspection. For sanitary dressing reasons, it is recommended that the tongue remain in the buccal cavity until after final carcass inspection.

The red offal shall be suspended from the hook in such a way that the cranial ventral surfaces of the lungs face towards the Inspector. This means that the heart (pericardial sac incised), cranial ventral portions of the lungs, pleural surface of the diaphragm (skirt meat), and dorsal surface of the liver are readily visible. The hepatic lymph node remains with the grey offal and, therefore, the liver need not be manipulated to see both surfaces.

Where the trachea has been mechanically damaged during carcass dressing and the pluck is normally suspended by the larynx, the pluck may be suspended by placing the junction of the heart base, where it attaches to the rest of the pluck, in the cradle of the hook and oriented so the heart is leading. All portions must still be visible for inspection without additional manipulation.

The red offal including the liver must be suspended high enough or offset so that it does not contact the surface of the grey offal.

Consistent or frequent loss of carcass parts that occur at a rate of 5% or greater over a specified time interval shall be immediately corrected by the operator.

8.1.2 Red Offal Presentation Defects – Hook

It is considered a presentation defect if:

  • the pluck is improperly suspended;
  • the pluck is rotated greater than 90° from normal;
  • the pluck is contaminated by GIT contents;
  • greater than 50% of any organ (defined above) is missing;
  • the pericardial sac is not incised; or
  • any organ is placed in the grey offal pan.

8.1.3 Red Offal Presentation – Tray / Table

Conventional red offal pluck presentation will include the larynx (mandibular lymph nodes and tongue may or may not be attached as indicated above), trachea, lungs, heart and the liver may or may not be included.

The described organs shall be consistently laid out as determined by the operator's presentation standard so that the Inspector may visually assess the dorsal surface of the lungs, the dorsal surface of the liver (if included as part of the organ group) and the trachea/larynx without having to perform any manipulation. The heart with the pericardial sac incised shall be readily visualized by lifting the anterior lobe of the lung. There shall be no GIT contamination of the red offal.

If the kidneys are presented on the tray/table, greater than 50% of each kidney shall be present and exposed.

8.1.4 Red Offal Presentation Defects – Tray / Table

It is considered a presentation defect if:

  • the red offal tissues are not in their normal quadrant or are rotated greater than 45° from the schematic standard;
  • the red offal is contaminated by GIT contents;
  • greater than 50% of any organ (defined for the purpose of presentation testing as the heart; liver and lungs) is missing or obscured from vision;
  • the pericardial sac is not incised;
  • the dorsal surfaces of the lungs and liver are not visible; or
  • the kidneys are presented on the tray/table and greater than 50% of each kidney is not present or exposed.

8.2 Grey Offal

Grey offal is presented in a variety of configurations. In those configurations where the liver is separated from the GIT, the liver shall be removed from the intestinal pack in such a manner that the hepatic lymph node is left attached to the intestinal peritoneum so it may be readily visualized by the Inspector. Grey offal presentation normally includes the gastrointestinal tract, spleen, uterus and bladder and shall be presented in such a way that the mesenteric and hepatic lymph nodes (if liver not present) and spleen are easily visible so the Inspector does not have to perform any manipulation.

8.3 Grey Offal Presentation – Pan

Each portion of grey offal in the pan presentation is to be found consistently in the same general region of the pan according to the operator's presentation schematic. With full or gaseous gastrointestinal tracts, it may be necessary for the Inspector to move the interfering cecum or colon. Greater than 50% of all organs (defined for the purposes of viscera presentation testing as the mesenteric lymph node chain, hepatic lymph node and spleen) must be visible on presentation and no portion of the grey offal shall be outside of the pan.

Contamination alone of the intestinal portions of the grey offal with ingesta or fecal material is not a reason for presentation failure unless it impedes the inspection procedure.

8.4 Grey Offal Presentation – Tray / Table

The grey offal in this configuration can include the liver in addition to the intestinal pack and its other associated organs. The intestinal tract shall be laid out such that greater than 50% of all organs are visible on presentation. The liver shall be placed in a location on the tray or table such that it does not obstruct the visualization of the intestinal tract. The dorsal surface of the liver shall be completely exposed for visual inspection.

There shall be no spillage of organs or parts outside the tray/table and there shall be no common contact with portions from other adjacent carcasses.

8.5 Grey Offal Presentation Defects

It is considered a presentation defect if:

  • the grey offal tissues are not in their normal quadrant or are rotated more than 45° from the schematic standard;
  • any portion of the grey offal is outside the pan/tray/table;
  • greater than 50% of any organ (defined for the purpose of presentation testing as the mesenteric lymph node chain, hepatic lymph node, spleen and liver, if applicable) is missing; or
  • greater than 50% of an organ is not visible due to obstruction by other tissues or major contamination.
