What is the standard percentage for the Salmonella verification threshold?

• A. 7.5%
• B. 5%
• C. 10%
• D. 15%

Answer: (A)

Verifications thresholds set a limit on how many samples test positive for Salmonella during verification sampling. This helps determine whether the preventive controls are effectively limiting contamination. The standard threshold used in Salmonella verification programs is seven and a half percent. This target strikes a balance: it’s low enough to catch recurring contamination patterns, but not so low that normal variation causes continual corrective actions. If verification results exceed this level, you would initiate corrective actions and re-verify to confirm the issue is resolved. The other values would be either too strict or too lenient compared with the widely accepted benchmark.
