FDA issues norovirus warning on frozen oysters from South Korea

The U.S. Food and Drug Administration has issued a warning regarding specific frozen, raw half-shell oysters harvested from South Korea that may be at risk of contamination with norovirus. The agency recommends that restaurants and retailers discard these products, and individuals showing symptoms should seek medical advice or contact the FDA. A recent outbreak of norovirus illnesses linked to oyster consumption from South Korea prompted the FDA to issue the warning. The affected oysters, identified with Lot Code: B250130 and harvested on Jan. 30, may have been distributed in ten U.S. states. Khee Trading Inc. of Compton, Calif., has initiated a recall of the oysters processed by JBR KR-15-SP. The FDA emphasizes that norovirus-contaminated shellfish, such as oysters, may appear normal in appearance, smell, and taste. Symptoms of norovirus include diarrhea, vomiting, and stomach pain, with dehydration being a concern, particularly for vulnerable groups. Good hand hygiene and thorough cleaning practices are recommended to reduce the risk of cross-contamination. Previously, in June 2024, the FDA also cautioned about frozen raw half-shell oysters from South Korea potentially contaminated with norovirus, which were exclusively sold in California.
