FDA warns of norovirus-tainted raw oysters and clams from Washington state, now hitting restaurants and stores in nine states, putting families at risk from invisible contamination.
Story Snapshot
- FDA alerts on March 9, 2026, for raw oysters from Drayton Harbor Oyster Company and Manila clams from Lummi Indian Business Council, harvested February 13 to March 3.
- Clams are distributed to Arizona, California, Florida, Georgia, Illinois, Nevada, New York, Oregon, and Washington; oysters are limited to Washington.
- Norovirus causes severe stomach illness with symptoms such as diarrhea, vomiting, and fever, typically striking 12-48 hours after exposure, despite a normal appearance.
- Triggered by the Washington Department of Health outbreak detection on March 4, no confirmed illnesses yet, but precautionary disposal is urged.
Alert Details and Harvest Origins
Drayton Harbor Oyster Company harvested raw oysters under tag WA-1723-SS from Drayton Harbor, Washington, between February 13 and March 3, 2026.
Lummi Indian Business Council harvested Manila clams under WA-0098-SS during the same period from the same location. The FDA issued its public health alert on March 9, directing restaurants and retailers not to serve or sell these products.
Consumers must discard any in their possession. Norovirus contamination poses risks even when shellfish look, smell, and taste normal, as these filter feeders concentrate viruses from polluted waters, such as sewage runoff.

Distribution Scope and Health Risks
Manila clams reached restaurants and retailers in nine states: Arizona, California, Florida, Georgia, Illinois, Nevada, New York, Oregon, and Washington, with possible spread to others. Oysters stayed in Washington. The Washington Department of Health notified the FDA on March 4 of an outbreak of norovirus-like illness linked to raw oyster consumption.
Symptoms include diarrhea, vomiting, nausea, stomach pain, fever, headache, and body aches, appearing 12-48 hours post-exposure and lasting up to three days. Vulnerable groups, such as the immunocompromised, face a greater risk from this highly contagious calicivirus.
Stakeholders and Response Actions
The FDA coordinates the interstate response, prioritizing public safety through rapid alerts. The Washington Department of Health led the initial detection.
Harvesters Drayton Harbor Oyster Company and Lummi Indian Business Council, a tribal entity, now handle compliance amid economic pressures. Restaurants and retailers must dispose of inventory immediately.
FDA monitors distribution and aids states. Consumers showing symptoms should seek medical care promptly. This underscores the need for robust oversight in shellfish harvesting to shield American families from unseen threats.
Historical Context and Patterns
Past incidents reveal recurring norovirus dangers in shellfish. In February 2026, Canadian Stellar Bay oysters were recalled after outbreaks in Washington and California.
Korean imports were subject to recalls in 2025 after a Utah outbreak and in 2024 after California cases. Domestic harvests like this one highlight vulnerabilities in U.S. waters, too.
Shellfish bioaccumulate viruses without altering taste or appearance, amplifying risks to raw consumption. Enhanced traceability and water testing remain critical to prevent disruptions to local economies and family dinner tables.
Short-term effects include product disposal, restaurant menu changes, and consumer caution. Harvesters face losses, while long-term measures may involve stricter testing in Drayton Harbor and potential closures.
Public scares could cut demand for raw seafood, pressuring agencies to speed up detection. This alert reinforces demands for limited government intervention focused on real protections, not overreach, ensuring food safety without stifling American industries.
