Fish Exposed to Industrial Pollutants: Avoid fish from contaminated lakes and rivers that may be exposed to high levels of polychlorinated biphenyls. This is primarily for those who fish in local lakes and streams. These fish include: bluefish, striped bass, salmon, pike, trout, and walleye. Contact the local health department or Environmental Protection Agency to determine which fish are safe to eat in your area. Remember, this is regarding fish caught in local waters and not fish from your local grocery store.
Raw Shellfish: The majority of seafood-borne illness is caused by undercooked shellfish, which include oysters, clams, and mussels. Cooking helps prevent some types of infection, but it does not prevent the algae-related infections that are associated with red tides. Raw shellfish pose a concern for everybody, and they should be avoided altogether during pregnancy.
