California health officials say raw oysters from British Columbia are linked to a recent outbreak of norovirus illnesses in the state, prompting warning for consumers to avoid eating raw oysters harvested from south and central Baynes Sound, in British Columbia, Canada.
In California, as of April 27, approximately 100 individuals have reported illness after they consumed raw British Columbian oysters sold by restaurants and retailers throughout the state. Laboratory testing has confirmed norovirus infection in several patients from both California and Canada. Although the number of reported new illnesses has decreased during the last week, the investigation is ongoing.
Canada has reported 172 cases of gastrointestinal illness linked to consumption of raw oysters.
