Dozens get sick with ‘norovirus-like’ illness after eating raw B.C. oysters

Raw Oyster Consumption Linked to Norovirus Outbreak in British Columbia

Health officials in British Columbia have issued a warning following an outbreak of gastrointestinal illnesses linked to the consumption of raw oysters. At least 64 cases have been reported since November 1 in the Vancouver Coastal Health, Fraser Health, and Island Health regions. The illnesses are said to be \”norovirus-like\” in nature, causing symptoms such as diarrhea, vomiting, and stomach pain.

The B.C. Centre for Disease Control and provincial health authorities have advised the public to be cautious when consuming raw or undercooked oysters, especially for those who may be at higher risk of severe illness, such as children, older adults, or individuals who are immunocompromised. Norovirus, a common winter virus, can lead to dehydration and other serious complications in vulnerable populations.

As a precautionary measure, federal agencies have temporarily closed some areas of the province to commercial shellfish harvesting, including parts of Baynes Sound west of Denman Island. This decision was made to prevent further cases of illness while investigations are underway.

Norovirus is highly contagious and can be easily spread through person-to-person contact or by consuming contaminated food or water. Oysters, in particular, can become contaminated with the virus if they are harvested from marine environments where norovirus is present. To reduce the risk of illness, health officials recommend cooking oysters to an internal temperature of 90°C for 90 seconds before consumption.

While no hospital admissions have been reported in connection to this outbreak, individuals experiencing symptoms of norovirus are urged to seek medical attention if necessary. It is essential to practice proper food safety measures, especially during the holiday season when the consumption of raw seafood is common.

By raising awareness about the risks associated with raw oyster consumption, the B.C. Centre for Disease Control and regional health authorities aim to prevent further cases of illness and protect public health. Stay informed and stay safe when enjoying seafood this winter.
