Norovirus Outbreak Linked to Oysters Sickens Dozens in Canada and U.S.

Health officials warn against consuming raw oysters after illnesses reported in British Columbia and Los Angeles, with recalls issued for potentially contaminated shellfish.

At least 64 cases of gastrointestinal illness linked to raw oysters have been reported in British Columbia between November 1 and December 18, prompting warnings from health authorities.
A separate outbreak in Los Angeles sickened over 80 attendees at a restaurant event on December 3, with some requiring hospitalization, though no deaths have been reported.
The outbreaks have been traced to oysters potentially contaminated with norovirus, a highly contagious virus often linked to untreated sewage in shellfish-growing waters.
Recalls have been issued for specific oyster products from British Columbia and Washington state, with health officials advising against consuming raw or undercooked shellfish from these regions.
Experts recommend cooking oysters thoroughly to eliminate the risk of illness and caution consumers, especially vulnerable groups, to verify the source and handling of shellfish before consumption.
