Decision Tree for Hazard Analysis Critical Control Point-based Inspection Program Presentation Testing. Description follows.

Description of the Decision Tree for HIP Presentation Testing

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 presentation performance testing as detailed in section 6, section 7, section 8 and section 9 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 10th consecutive passed test, switch to the reduced mode (box # 2).
  3. If this is the 2nd rejected test in the last 5 tests, implement corrective actions, notify the canadian food inspection agency and switch to tightened mode (box number 3).

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

Continue in reduced mode until the following occurs: when a reduced mode test fails, implement corrective actions and switch to normal mode (box number 1).

Box number three (3) – tightened mode

  1. Suspend random testing and implement corrective action(s) and test within 15 minutes. Thereafter, test every 15 minutes.
  2. If first test and next subsequent 4 tests pass, return to box number 1.
  3. If first test fails, implement corrective action(s) and test again in 15 minutes.
  4. If any 2 tightened mode tests are rejected in a window of 5 tests, 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.
  2. If subsequent test passes, increase line speed 10%. If the next subsequent 4 tests pass, return to box number 1.
  3. Any subsequent test failure, 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.
