The establishment must address the relevant hazards of concern when producing RTE products in the HACCP or SSOP plan. Must they also perform sampling in the RTE processing environment for Lm Alternative 1?

• A. Yes
• B. No
• C. Only if a problem exists
• D. Not required

Answer: (B)

Controlling Listeria in ready-to-eat (RTE) products is about having robust preventive controls in the HACCP or SSOP plan. Under this approach, the emphasis is on ensuring the processes and sanitation measures are designed to prevent contamination and growth of Lm, rather than relying on routine environmental testing as a required control activity.

In Lm Alternative 1, you address relevant hazards through those preventive controls and verification activities tied to your HACCP/SSOP plan. Environmental sampling for Lm in the RTE processing environment is not a mandated requirement of this alternative. It can be used as a verification tool or as part of a different strategy, but simply selecting Alternative 1 does not obligate you to perform routine environmental Lm sampling. If problems arise, or if an establishment adopts a different approach that relies on environmental testing (such as Alternative 2), then sampling requirements may differ.
