Wang Globalnet of Vernon, CA has recalled (https://www.issc.org/news-notices) frozen, raw, half-shell oysters with Lot Code: B250112, harvested from Designated Area No. 1 in the Republic of Korea (ROK) on Jan. 12, 2025, and processed by JBR KR-15-SP in Tongyeong-si, ROK because they may be contaminated with norovirus.

Shellfish, such as oysters, contaminated with norovirus can cause illness if eaten, and potentially severe illness in people with compromised immune systems. Food containing norovirus may look, smell, and taste normal. Consumers of these products who are experiencing symptoms of illness should contact their healthcare provider and report their symptoms to their local Health Department. Diarrhea, abdominal cramps, nausea, vomiting, and fever may be associated with gastroenteritis infections caused by this organism.

Symptoms of Norovirus

People of all ages can get infected and sick with norovirus. The most common symptoms of norovirus are diarrhea, vomiting, nausea, and stomach pain. Other symptoms include fever, headache, and body ache.

A person usually develops symptoms 12 to 48 hours after being exposed to norovirus. Most people with norovirus illness get better within 1 to 3 days.

If you have norovirus illness, you can feel extremely ill, and vomit or have diarrhea many times a day. This can lead to dehydration, especially in young children, older adults, and people with other illnesses. Symptoms of dehydration include decrease in urination, dry mouth and throat, and feeling dizzy when standing up. Children who are dehydrated may cry with few or no tears and be unusually sleepy or fussy.

If you think you or someone you are caring for is severely dehydrated, call your healthcare provider.

Wash hands with warm water and soap following the cleaning and sanitation process.
Retailers, restaurants, and other food service operators who have processed and packaged any potentially contaminated products need to be concerned about cross-contamination of cutting surfaces and utensils through contact with the potentially contaminated products.
Retailers that have sold bulk product should clean and sanitize the containers used to hold the product.
Regular frequent cleaning and sanitizing of food contact surfaces and utensils used in food preparation may help to minimize the likelihood of cross-contamination.

Recommendations for Consumers

Consumers should not eat these potentially contaminated oysters.

Consumers who have symptoms of norovirus infection should contact their health care provider to report their symptoms and receive care.
