Uncooked meats, raw sushi, unheated deli meats are a no-no, due to the risk of listeria. It's recommended to eat about 8 oz of fish per week, but not shark, mackeral, albacore tuna, and a few others that contain high levels of mercury. Salmon, light chunk tuna, shrimp, talapia are just a few that can be eaten during pregnancy. Soft cheeses, like brie or the queso fresco, and blue-veined/moldy cheeses, like some blue cheeses, aren't recommended for consumption.
