Deli cold cuts and uncooked hot dogs, even when properly refrigerated, are sources of the bacteria listeria, which can lead to listeriosis, a rare but dangerous infection that can cause miscarriage, preterm labor or stillbirth, or blood poisoning in your baby, according to the American Pregnancy Association. If your cravings for a deli sandwich or hot dog are too much to bear, make sure to heat the meat until it is steaming before you indulge.
