Where is the livestock carcass zero tolerance standard verified?

• A. In the cooler, after all trimming, washes, and interventions have been applied
• B. During final packaging
• C. At or after the post mortem rail, before final washes or other interventions are applied
• D. Only after the establishment has performed any planned microbial testing

Answer: (C)

The point of verification is on the line where carcasses are handled after slaughter, specifically at or after the postmortem rail, and before any final washes or other interventions are applied. This ensures the carcass is evaluated in its unaltered state so any visible contamination or defects are caught and removed before processes that could mask or modify them (like washing or trimming). If verification happens later, such as in the cooler after interventions or during packaging, issues could already have been altered or hidden. Microbial testing, while important, does not substitute for this visual verification of zero tolerance.
