When is the livestock zero tolerance standard for head, cheek, and weasand meat and edible offal verified?

• A. After all establishment interventions have been applied
• B. At or after the post-mortem rail, before final washes or other interventions are applied
• C. Only after the establishment has performed any planned microbial testing
• D. Any time prior to chilling

Answer: (A)

Verification of the livestock zero-tolerance standard for head, cheek, and weasand meat and edible offal is done after all establishment interventions have been applied. The point of zero tolerance is that there is no detectable adulterants on these parts, so you need to confirm the interventions actually eliminated contamination before the product moves on in processing.

Checking earlier, such as at the post-mortem rail before interventions, or tying verification to planned microbial testing, wouldn’t reflect the outcome of the required processing steps. Verification before chilling or before completing interventions could allow contaminated material to pass if the interventions aren’t yet applied, so the correct timing is after those interventions have been completed.
