Listeriosis, a type of food poisoning that's 20 times more likely to affect pregnant women than other adults, can result in premature delivery, miscarriage, or stillbirth if left untreated. If you have flulike symptoms such as fever, vomiting, diarrhea, or muscle aches for more than 12 hours after eating, call your gynecologist. The bacteria that causes listeriosis is found in soft cheeses such as feta, Brie, Camembert, blue cheese, and queso blanco; lunch meats; unpasteurized milk; and pates and other meat spreads. Avoid these foods if you're pregnant.
Some fish may contain high levels of mercury, which can damage an unborn baby's nervous system. Avoid eating shark, swordfish, tilefish, and king mackerel. Freshwater fish such as salmon, pike, and trout could also be tainted, so check with your state or local health department.
