The U.S. Department of Agriculture (USDA) and the Federal Department Food and Drug Administration (FDA) have issued a warning to pregnant women, older adults, and people with weakened immune systems that they are at higher risk for a life-threatening infection called listeriosis, caused by Listeria monocytogenes present in certain ready-to-eat foods. They provide the following advice to at-risk consumers of foods that have a greater likelihood of containing Listeria monocytogenes:

Do not eat hot dogs and luncheon meats, unless they are reheated until steaming hot.
Do not eat soft cheeses such as Feta, Brie and Camembert cheeses, blue-veined cheeses, and Mexican-style cheeses such as "queso blanco fresco." Cheeses that may be eaten include hard cheeses; semi-soft cheeses such as mozzarella; pasteurized processed cheeses such as slices and spreads; cream cheese;and cottage cheese.
Do not eat refrigerated pâ´©s or meat spreads. Canned or shelf-stable pâ´©s and meat spreads may be eaten
Do not eat refrigerated smoked seafood, unless it is contained in a cooked dish, such as a casserole. Refrigerated smoked seafood, such as salmon, trout, whitefish, cod, tuna or mackerel, is most often labeled as "nova-style," "lox," "kippered," "smoked," or "jerky." The fish is found in the refrigerator section or sold at deli counters of grocery stores and delicatessens. Canned or shelf-stable smoked seafood may be eaten.
Do not drink raw (unpasteurized) milk or eat foods that contain unpasteurized milk.
