The Centers for Disease Control and Prevention (CDC) an estimated 103 norovirus illnesses linked to raw oysters from British Columbia.
The following states have been affected: CA, CO, FL, HI, IL, MA, MN, NJ, NV, NY, OR, TX and WA.
CDC is working with state and local partners to determine a more accurate number of illnesses in this outbreak.
The U.S. Food and Drug Administration (FDA) is working with federal, state, and local officials, and with Canadian public health authorities regarding a norovirus outbreak linked to raw oysters from British Columbia, Canada. The FDA has confirmed that potentially contaminated raw oysters harvested in the south and central parts of Baynes Sound, British Columbia, Canada, were distributed to restaurants and retailers in CA, CO, FL, HI, IL, MA, MN, NJ, NV, NY, OR, TX, and WA. It is possible that additional states received these oysters through further distribution within the U.S.
The FDA and the states conducted a trace forward investigation to determine where the raw oysters were distributed and to ensure they’re removed from the food supply. Retailers should not serve raw oysters harvested from the following harvest locations within British Columbia, BC 14-8 and BC 14-15, with harvest starting as early as January 31, 2022, which will be printed on product tags.
If eaten raw, oysters and other filter-feeding shellfish can contain viruses and bacteria that can cause illness or death. Anyone who consumes raw shellfish is at risk of contracting norovirus. Children younger than five years old, the elderly, and those people with weakened immune systems are more likely to have severe infections. Food contaminated with norovirus may look, smell, or taste normal. To avoid food poisoning from oysters, cook them well to a temperature of at least 145 degrees F.
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.
