What is the best prevention method against Listeria monocytogenes?

The most effective prevention method against Listeria monocytogenes is monitoring storage temperatures. Listeria is particularly well-known for thriving in cold environments, including refrigeration, which makes it essential to keep foods at appropriate temperatures to inhibit its growth.

By ensuring that storage temperatures are consistently below 40°F (4°C), you significantly reduce the risk of Listeria multiplication in food products. This is particularly critical for high-risk foods such as deli meats, dairy products, and ready-to-eat foods that may become contaminated.

While regular handwashing, cooking food thoroughly, and using pasteurized products are all important food safety practices, they do not specifically address the unique challenges posed by Listeria monocytogenes in terms of temperature and its capability to survive and grow in cooler conditions. Therefore, effective temperature control is paramount in preventing Listeria contamination and ensuring food safety.
