Jars of bar clams sold in P.E.I. and New Brunswick may contain the toxin that causes botulism, the Canadian Food Inspection Agency has warned.

St. Thomas Fish Market in New Brunswick is voluntarily recalling its product, St. Thomas bar clams, because they may contain Clostridium botulinum.

Toxins produced by the bacteria can cause botulism, a life-threatening illness.

There have been no illnesses reported, said the agency.

Food contaminated with these bacteria might not look or smell spoiled.

Symptoms include vomiting, blurred vision, slurred speech and muscle paralysis. Anyone with concerns should call their physician.
