The Public Health Agency of Canada (PHAC) is collaborating with provincial public health partners, the Canadian Food Inspection Agency (CFIA) and Health Canada to investigate an outbreak of norovirus and gastrointestinal illnesses involving four provinces: British Columbia, Alberta, Manitoba, and Ontario.

Investigation findings have identified consumption of spot prawns as the source of the outbreak. All of the individuals who became ill reported eating spot prawns before their illnesses occurred. More information is needed to determine how the spot prawns became contaminated with norovirus.

On May 31, 2022, the CFIA issued a food recall warning for several lot codes of live spot prawns that are associated with the illnesses under investigation. The recalled products have been sold in British Columbia, Alberta, Manitoba, and Ontario, and may have been distributed in other provinces and territories. The CFIA is continuing its food safety investigation, which may lead to the recall of other products. If other products are recalled, the CFIA will notify the public through updated food recall warnings.

Do not eat, use, sell or serve the recalled spot prawns. Check to see if you have the recalled spot prawns at home. If you do, throw them out and wash your hands.

The outbreak investigation is ongoing and additional actions to protect public health will be taken as needed. The public health notice will be updated as the investigation evolves.

As of June 1, 2022, there have been 48 cases of norovirus and gastrointestinal illness reported in the following provinces: British Columbia (11), Alberta (12), Manitoba (19), and Ontario (6). Individuals became sick between mid-May and late-May 2022, and no deaths have been reported. Although not all cases of illness have been tested, laboratory testing has confirmed the presence of a norovirus infection.

Mantab Inc. is recalling Below Zero brand whole, frozen raspberries because of possible norovirus contamination.

The recalled product has been sold in Quebec, Saskatchewan and Ontario.

Consumers, retailers, and restaurant owners should check to see if they have the recalled products in their homes or establishments. Recalled products should be thrown out or returned to the location where they were purchased.
