Decision Tree for Hazard Analysis Critical Control Point-based Inspection Program Finished Product Standards – Food Safety 1 Defect Testing. Description follows.

Description of the Decision Tree for HIP FPS – FS I Defect 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 10 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 number 2).
  3. If test is rejected, implement corrective actions, identify/detain lot for rework, notify the canadian food inspection agency and switch to tightened mode (box number 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. When a failure occurs, detain associated lot for rework procedures(fecal/ingesta/milk only), implement corrective action(s) as required, and go to box number 1. Consult Appendix E: Decision tree for carcass product rework. For small plants, a failed test must be followed by a test in normal mode in half an hour.

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. Upon a failure while in tightened mode go to box number 4 and immediately identify the failed lot associated with the test for rework procedures.

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

  1. If this is the 2nd rejected test in a window of 5, notify veterinarian in charge (or delegate), reduce the line speed by 10%, initiate corrective action(s) and test in 15 minutes. If any further failures occur go to # 5A
  2. If subsequent test passes, increase line speed 10%. If the next subsequent 4 tests pass, return to box number 1.
  3. If there is any failure while in tightened mode, detain lot for rework.

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, detain lot for rework, notify the veterinarian in charge.

Note: Any finished product standard of food safety category 1 testing failure resulting from tests related to Appendix A, Evisceration test, shall be treated in accordance with the International Organization for Standardization switching rules for the particular mode in which finish product standard was operating at the time of the test failure.
