Seafood can be contaminated with toxins, bacteria, and parasites. One example is Ciguatera poisoning, a toxin that is not destroyed by cooking seafood. Shellfish can be contaminated by algae, building up toxins to dangerous levels. Again, cooking will not eliminate this risk.
Rice can carry bacillus cereus, which infects and lives in uncooked rice. Cooking actually activates the spores and increases the risk of infection.
9. Deli meats:
Ham, hot dogs, salami, and other deli meats can be affected by listeria and other bacteria. Its important to cook hot dogs and back for at least 3 minutes before eating.
Listeria can grow on the skins of grit and vegetables, and salmonella outbreaks have been traced to berries, peppers, and tomatoes.
