Which Lm Alternative provides for control of Lm entirely through sanitation and sampling of food contact surfaces?

• A. Alternative 1
• B. Alternative 2 Choice 1
• C. Alternative 2 Choice 2
• D. Alternative 3

Answer: (D)

The main idea being tested is how Listeria monocytogenes risk can be controlled through different program designs, specifically whether a plan can manage Lm solely through cleaning, sanitizing, and verifying cleanliness on surfaces that touch food. The correct approach is the one that relies entirely on a strong sanitation program paired with regular sampling of food contact surfaces to verify that those surfaces remain clean and free of Lm. This means the plant would use validated cleaning and sanitizing procedures, documented sanitation schedules, and an ongoing environmental sampling plan to detect any Lm presence and trigger corrective actions if the tests show contamination. The emphasis is on preventing contamination at the surface level and proving it through surface testing, rather than relying on other control measures such as specific process controls or post-lethality treatments. Other approaches combine sanitation with additional controls, so they do not meet the criterion of being solely sanitation- and sampling-based.
