CDC details, “Products sold at deli counters, especially those sliced or prepared at the deli, can be contaminated with Listeria. Listeria spreads easily among deli equipment, surfaces, hands, and food. Deli products are kept refrigerated, but refrigeration does not kill Listeria.”

How to stay away from listeria?  

A detailed guideline was released by the CDC on how to stay away from listeria. The agency suggests, “Do not eat recalled deli products. Throw them away or contact stores about returns. People who are at higher risk for getting sick with Listeria, such as those who are pregnant, are aged 65 or older, or have a weakened immune system, should always avoid eating meats sliced at deli counters, unless heated to an internal temperature of 165°F or until steaming hot just before serving. Clean your refrigerator, containers, and surfaces that may have touched sliced deli meats.”
