19.6.2.7.6.7 Defect Detection Standards Decision Tree
Step 1: Process Evaluation
With Process Evaluation under Normal Control Sampling, done every hour for
13 or 20 sample units, there are two possibilities:
- Accepted Sample, which leads to Continue
Process Evaluation under Normal Control Sampling, which returns you to the
beginning.
- Rejected Sample: Advise the Canadian Food
Inspection Agency (for Food Safety-1, implement corrective measure(s) for the
specific defect group that failed, and proceed to Step 2: Corrective Measure(s)
Evaluation, or go directly to Step 3: Postchill Product Verification), which
leads to:
- Continue Process Evaluation under Normal Control Sampling, which returns
you to the beginning
- Implement corrective measures for specific defect group, which leads to
Step 2: Corrective Measure(s) Evaluation
Step 2: Corrective Measure(s) Evaluation
With Corrective Measure Evaluation for a specific defective defect group,
within 10 minutes (the approximate delay required in order to evaluate the
effect of the corrective measures at the Defect Detection Standards station)
and 13 or 20 sample units, there are two possibilities:
- Accepted Sample: Stop corrective
measure(s) evaluations. If applicable, carcasses entering the chilling process
are identified to mark the end of additional sampling after chilling.
or
- Rejected Sample: Nota Bene: Maximum of 3 failed tests after which the
corrective measures must be determined by the Veterinarian in Charge based on
the specifics of the issues:
- Replace staffing
- Additional staffing
- Line speed reduction
For one rejected sample under Food Safety-2, Food Safety-3, Dressing
Condition-1
Proceed to Step 3: Postchill Product Verification
Step 3: Postchill Product Verification
Postchill Product Verification, which is for a specific defective defect
group, applies on the entire affected lot, is done every 15 minutes and
requires 8 or 13 sample units, there are two possibilities:
- Accepted Sample: Stop post-chill
verification when corrective measure(s) evaluation is accepted, resulting in
identified product reaching the post-chill verification station; or
- Rejected Sample: Start post-chill product
segregation on subsequent carcasses until next accepted sample. Segregated
product shall be reworked and retested using the same sample size.
The Meat Inspection Regulations have precedence over this decision
