Sacramento – The California Department of Public Health (CDPH) is warning distributors and retailers not to sell or serve frozen raw oysters from JBR, Inc. in Tongyeongsi, Republic of Korea (ROK) because they may be contaminated with norovirus, a virus that can cause serious gastrointestinal illness.

As of April 24, 2024, there have been 33 confirmed and probable cases of norovirus reported among persons who consumed raw oysters at three San Diego County restaurants in late March and April 2024. Investigations by San Diego County public health officials and CDPH identified frozen raw oysters that were harvested on November 26, 2023, January 4, 2024 and February 15, 2024, and packed by JBR, Inc. (KR 15 SP) as the likely source of illness.   

Restaurants and retailers can protect customers by checking their inventory and shellfish labels, ensuring that potentially contaminated raw oysters are not available for purchase, and discarding any leftover contaminated product.

The Ministry of Oceans and Fisheries in the Republic of Korea advised the firm to voluntarily initiate a recall of the distributed lots. In addition, two California distributors, Great Wall Seafood LA LLC (April 18, 2024) (recalled lots B2311126 and B2240103) (PDF) and S.J. Distributors LLC (April 20, 2024) (recalled lot B240214) (PDF) have also issued recalls of the product. 

Anyone who becomes ill after eating raw oysters should contact their health care provider and report their illness to their local health department.  

Norovirus is a highly contagious virus and can be spread easily from person-to-person, through contaminated surfaces, and by eating contaminated food, including raw or undercooked oysters. Symptoms of norovirus usually begin 12 to 48 hours after a person has come in contact with the virus and can last for 1 to 3 days. Common symptoms include vomiting, diarrhea, nausea, and stomach cramps. People who develop symptoms of norovirus infection should consult their health care providers.
