What is the sampling minimum for chickens to prevent contamination?

• A. One per 22,000 or one weekly for smaller facilities
• B. One per 3,000
• C. One per 50,000
• D. One per 75,000

Answer: (A)

Surveillance sampling frequency is set to balance detecting contamination with practicality in poultry operations. For chickens, the minimum is one sample for every about 22,000 birds processed, and for smaller facilities at least one sample per week. This cadence gives a reasonable chance of catching contamination if it’s present at a detectable level across a flock, without imposing an unrealizable testing burden. Why this works well: in large flocks, contamination may be unevenly distributed, so testing at this scale provides a representative check without needing constant sampling. For smaller facilities, weekly sampling keeps consistent oversight even when production volume fluctuates, helping ensure problems are identified and addressed promptly. Other frequencies are less appropriate because sampling far more often (e.g., one per 3,000 birds) can be unnecessarily burdensome, while sampling much less often (e.g., one per 50,000 or 75,000) increases the risk that contamination goes undetected and affects a larger portion of products before corrective actions are taken.
