The CFIA is conducting an investigation, which, it says, may lead to the recall of other products.

More information on the recall can be found on the CFIA site.

Recalled products should be thrown out or returned to the store where they were purchased.

Those infected with norovirus usually develop gastroenteritis within 24 to 48 hours, and the illness generally begins suddenly.

The virus usually leaves patients' systems within one or two days.
