The Canadian Food Inspection Agency is warning the public not to consume certain mussels that may contain diarrhetic shellfish poisoning biotoxin.

The affected mussels were harvested in British Columbia by Island Sea Farms Inc. between July 19 and Aug. 2.

They have been distributed in B.C., Alberta, Saskatchewan, Manitoba, Ontario and possibly other provinces and territories under the brand names Saltspring Island, Albion Fisheries Ltd, Pacific Rim Shellfish Corp., Albion, and B & C Food.

Consumers who purchased raw mussels between July 19 and Aug. 6 should check with their retailer to determine if they have product covered by the recall.

Health Canada, along with health officials in B.C., say they are investigating reports of some illnesses associated with the consumption of the mussels.

Food contaminated with DSP biotoxin may not look or smell spoiled but can cause diarrhea, nausea, vomiting, abdominal cramps and chills.
