Oysters Sold in 10 States May Make People ‘Extremely Ill’ With Norovirus

The Food and Drug Administration (FDA) has issued a warning for oysters sold in 10 states after reports of illness, the agency announced Wednesday. Shellfish can be contaminated with norovirus, a virus that can cause serious stomach symptoms, including nausea and vomiting. It is also the most common cause of foodborne illness in the United States.

Affected oysters originate from British Columbia, Canada, and can be identified using the following information:

• Collected by: Stellar Bay Shellfish Ltd. from British Columbia, Canada
• Brands: Kusshi, Chrome Point, Stellar Bay and Stellar Bay Gold
• Harvest area: BC 17-20 (Nanoose Bay) CLF #1401656
• Harvest dates: between December 22, 2025 and February 4, 2026

The shellfish were distributed to restaurants and retailers in California, Colorado, Florida, Hawaii, Illinois, Maryland, Nevada, New York, Pennsylvania and Washington. The FDA also warned that the oysters may have been distributed to other states as well.

At grocery stores and restaurants, check where your oysters come from and do not eat any affected oysters.

If you think you have eaten contaminated oysters, watch for symptoms of norovirus, including diarrhea, abdominal cramps, nausea, vomiting and fever.

The FDA urges anyone experiencing these symptoms after eating the affected shellfish to contact their health care provider and report their symptoms to their local health department.
