Raw Oysters and Norovirus

If eaten raw, oysters and other filter-feeding shellfish can contain viruses and bacteria that can cause illness or death. Anyone who consumes raw shellfish is at risk of contracting norovirus. Children younger than five years old, the elderly, and those people with weakened immune systems are more likely to have severe infections. Food contaminated with norovirus may look, smell, or taste normal. To avoid food poisoning from oysters, cook them well to a temperature of at least 145 degrees F.
