6.1 Introduction to Presentation Testing

The provision for uniform presentation standards is a key element in the implementation of the HIP. It provides not only for consistency in the presentation of carcasses and their portions but it also reduces potential food safety concerns and offers an early indication as to whether certain carcass dressing procedures are in control or not. 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, minimum presentation standards also ensure effective and efficient inspection. 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.

6.2 Plant Responsibilities

Regardless of the size of the establishment, it is the responsibility of every operator to ensure that carcasses and their parts are presented for post-mortem inspection in such a way as to permit proper examination by CFIA inspectors. To that effect, the operator and the VIC shall agree on a presentation schematic that will become the standard for the establishment.

Plant management is responsible for implementing the prescribed presentation standards for heads (including mandibular lymph nodes), viscera and carcasses by plant personnel. The operator shall designate accredited persons to schedule and conduct Presentation Tests and initiate corrective action whenever the required standards are not met.

The monitoring function can be shared between plant production and QA or it may be performed by QA alone if the operator so chooses. The operator shall notify the VIC/delegate when required as indicated in Appendix B: Decision Tree for HIP Presentation Testing.

6.3 Excessive Line Speed

Line speed is checked at the time of Presentation testing. If on any test, the line speed is found to exceed the currently allowed rate, an immediate line speed reduction to the allowed rate is required. After any line speed reduction the line speed shall be rechecked within 15 minutes. Upon test, if the line speed is again found to be above the allowed rate (+ 1% allowance), the VIC/delegate must be notified and a 10% reduction from the current maximum allowed line speed shall be applied.

6.4 Presentation Performance Standards

The operator and the VIC shall collaborate and mutually agree upon an acceptable method and orientation for presenting the carcass and its portions for CFIA inspection. Orientation for proper presentation is from the Inspector's viewpoint facing the moving chain or table. Once approved by the VIC, a schematic diagram depicting the presentation standard shall be included in the operator's written program and a copy of the schematic shall be posted in a conspicuous location in the QA office and the CFIA office. All plants, regardless of size, must have a presentation schematic.

6.5 Presentation Performance Scoring

Scoring of presentation errors is based on the ISO attribute system using Sampling Plan ISO 2859-1 (S-3). In each of the three presentation categories (heads, carcass and viscera) a list of defects or attributes has been established to ensure that a minimum standard of presentation is maintained in each category. ISO switching rules for Reduced, Normal and Tightened modes apply to this standard. Any attribute (condition/defect) detected shall be scored as a defect.

Because of the variation in the configuration of federally registered establishments, the AQL for each presentation category will vary depending on the complexity and number of attributes assigned to that category. Once presentation test AQLs are determined for an establishment, they will be recorded in the company's written program.

Three basic principles are applied when a plant monitor or the CFIA performs a Presentation Test. These principles are:

  1. testing in Normal, Tightened, or Reduced modes shall continue unchanged except where indicated by the decision tree (see Appendix B: Decision Tree for HIP Presentation Testing);
  2. a sample unit (head, viscera, or carcass) fails if one or more attributes are scored; and
  3. there is a maximum of one failure per sample unit.

All presentation test results are to be recorded on the applicable CFIA forms:

  • CFIA HIP 002A: HIP Presentation Testing – Heads (MLN presented on head)
  • CFIA HIP 002B: HIP Presentation Testing – Heads (MLN presented off head)
  • CFIA HIP 003A: HIP Presentation – Viscera (Hook & Pan)
  • CFIA HIP 003B: Presentation Testing – Viscera (Tray / Table)
  • CFIA HIP 004A: HIP Presentation Testing – Carcasses (MLN presented on head)
  • CFIA HIP 004B: HIP Presentation Testing – Carcasses (MLN presented off head).

An operator may commence HIP operations and activities using in-plant data to establish the initial minimum performance limit for each of the presentation tests.

However, after a period not exceeding six months, the operator shall meet the minimum national AQL standards listed in Appendix G. If the operator is not able to meet these standards after the specified time period the VIC shall notify and consult with the RVO. Consultation may also include the National Program Specialist.

Presentation Testing Modes

All facilities commencing inspection for the first time under the HIP shall start testing in Normal mode. Sample size and test frequency is based on the operator's definition of a lot (see Table 4.1: HIP SPC Testing Frequencies).

Normal Mode

The operator must continue to successfully pass a minimum of four out of five consecutive random tests to maintain Normal mode status. Should the operator fail two presentation tests within any window of five consecutive tests, random testing shall be suspended and the testing mode shall be switched to Tightened on the subsequent test. The CFIA shall be notified of the mode change and test failure. The operator shall investigate and correct the cause of the failure. Alternately, after 10 consecutive successful tests in Normal mode, the operator may change to Reduced mode.

Tightened Mode

Upon entering Tightened mode random testing shall be suspended and another test shall be conducted within 15 minutes of the previously failed Normal mode test and testing shall continue every 15 minutes thereafter until Normal mode is restored. Five consecutive successful tests must be passed in order to return to Normal mode. At that time, random testing shall be resumed.

After any two failures in a window of five consecutive tests, while in Tightened mode, the operator shall notify the VIC/delegate. Consultation shall occur between the operator and the CFIA to determine the cause of the presentation under performance. A 10% line speed reduction shall be exercised prior to resuming operations.

Reduced Mode (Elective)

Ten consecutive successful test scores in Normal mode shall be achieved before the operator can switch to Reduced Mode. Any single failure of a test score in Reduced mode will move the operator back to Normal mode. The operator should initiate corrective actions as deemed necessary.
