The Food and Drug Administration has issued a recall for raw oysters and clams due to potential norovirus contamination, affecting products distributed to nine states across the country.

The recalled shellfish were harvested between February 13 and March 3 in Washington state. The contaminated products have been distributed to Arizona, California, Florida, and New York, among other states not specifically identified in the recall notice.

The FDA is advising consumers, restaurants, and retailers to immediately dispose of any affected oysters and clams rather than consume or serve them. Norovirus is a highly contagious virus that can cause severe gastrointestinal illness, including nausea, vomiting, and diarrhea.

Shellfish can become contaminated with norovirus when they filter water containing the virus, typically from sewage contamination in harvesting areas. The virus is particularly concerning because it can survive in shellfish even when properly refrigerated.

Anyone who has consumed the recalled products and is experiencing symptoms should contact their healthcare provider. The recall represents a precautionary measure to prevent potential foodborne illness outbreaks associated with contaminated shellfish.
