Norovirus alert: FDA warns of contaminated raw oysters from Mexico

Raw oysters from certain parts of Mexico could be a source of norovirus, the U.S. Food and Drug Administration has warned. Doctors weigh in on the risks.

Consumers are also advised against eating these oysters and to seek medical attention for any symptoms of norovirus. "The most vulnerable people are the very young or old or immunocompromised."
