A multi-provincial oyster recall has been initiated in Canada due to a suspected norovirus outbreak linked to raw oyster consumption. The Canadian Food Inspection Agency (CFIA) issued the recall on Saturday, targeting specific lots of Fanny Bay, Sunseeker, and Cloudy Bay oysters distributed by Taylor Shellfish Canada ULC. The recall encompasses British Columbia, the epicenter of the suspected outbreak, as well as Alberta and Ontario. The affected oysters were primarily harvested and processed in early December, with some potentially dating back to late November. The CFIA’s ongoing food safety investigation may lead to further recalls. Consumers are strongly advised against consuming the recalled oysters and are urged to dispose of them or return them to their point of purchase.
The recall follows reports of numerous gastrointestinal illnesses in British Columbia potentially linked to raw oyster consumption. The BC Centre for Disease Control (BCCDC) issued a warning regarding 64 cases of a “norovirus-like” illness reported between November 1 and December 18. The affected individuals reported consuming raw oysters sourced from various restaurants and retailers within the province. Symptoms experienced included diarrhea, vomiting, and stomach pain, with some cases requiring emergency department visits, though no hospitalizations were reported.
Noroviruses are a group of highly contagious viruses notorious for causing gastroenteritis, commonly referred to as “stomach flu.” Transmission occurs primarily through fecal-oral routes, involving direct contact with contaminated feces or vomit. Norovirus can contaminate food sources, particularly oysters, which filter-feed and can accumulate the virus from contaminated water sources. The Public Health Agency of Canada (PHAC) highlights the vulnerability of oysters to norovirus contamination due to their propensity for filtering sewage-contaminated water.
The onset of norovirus symptoms typically occurs within 12 to 48 hours after exposure. While most individuals recover within a few days, severe cases can necessitate hospitalization and intravenous fluid administration. The CFIA emphasizes the importance of seeking medical attention if experiencing symptoms after consuming recalled oysters. The agency’s investigation underscores the commitment to food safety and protecting public health.
The recall and subsequent investigation highlight the potential risks associated with consuming raw oysters, particularly during specific seasons or from regions with potential water contamination. Public health agencies and food safety regulators play a crucial role in identifying and mitigating such risks, safeguarding consumer health. The collaborative efforts between the CFIA and BCCDC demonstrate the coordinated approach to addressing food-borne illness outbreaks and preventing further spread.
This incident serves as a reminder of the importance of food safety practices, including proper handling and storage of seafood. Consumers should be aware of recall notices and adhere to recommendations provided by health authorities. The investigation’s findings will provide valuable insights into the source of the contamination and inform future preventative measures. Public awareness and adherence to safety guidelines are essential for minimizing the risk of norovirus and other foodborne illnesses.
