Certain Pacific Ocean oysters were recalled late Friday (July 19) from the marketplace due to a marine biotoxin which causes Paralytic Shellfish Poisoning, according to the Canadian Food Inspection Agency (CFIA).   No illnesses are yet associated with the recall.

Oysters on the recall list were distributed in Alberta, British Columbia, and Ontario. Retail outlets are targeted in the recall, which was  triggered by CFIA testing.

The CFIA is conducting a food safety investigation, which may lead to the recall of other products. If other high-risk products are recalled, the food safety agency will notify the public through updated Food Recall Warnings.

The CFIA is verifying that retail businesses are removing the recalled product from the marketplace.
