Must they also perform sampling in the RTE processing environment for Lm Alternative 1?

• A. Yes
• B. No
• C. Depends on the product
• D. Not required for any alternative

Answer: (B)

The main idea is that how you monitor for Listeria depends on the control strategy chosen. For Lm Alternative 1, the plan is built around product-focused controls and a validated process that prevents or eliminates Lm in the finished product, so routine sampling of the RTE processing environment isn’t required. In this approach, verifying safety relies on product testing and the effectiveness of the kill step or other controls, rather than environmental surfaces. Environmental sampling would be more relevant in plans where sanitation efficacy or post-lethality contamination risks need ongoing verification, but that isn’t mandated under this alternative.
