An establishment that exposes ready-to-eat (RTE) product to the environment post-lethality must:

• A. They must perform an additional cooking step
• B. They are shelf stable and safe to eat at ambient temperatures
• C. They are subject to the regulatory requirements of 9 CFR Part 430 (Lm regulations)
• D. They must develop a CCP at the final packaging step

Answer: (C)

Post-lethality exposure creates a risk from Listeria monocytogenes on ready-to-eat products, so regulatory controls are focused on preventing this contamination after the kill step. The rules that apply are the Lm regulations in 9 CFR Part 430, which set requirements for control of Listeria monocytogenes in post-lethality exposed RTE meat and poultry products. These regulations cover appropriate process controls, sanitation, environmental monitoring, validation, and verification to manage the risk after lethality. That’s why the correct choice is that they are subject to 9 CFR Part 430 (Lm regulations).

An extra cooking step isn’t mandated by these rules for post-lethality exposure, the product isn’t inherently shelf-stable just because of exposure, and the issue isn’t resolved by establishing a CCP at final packaging alone—the specific regulatory framework for this exposure risk is the Part 430 Lm regulation.
