The manager of the M&M Meat Shop in Charlottetown says any customers who bought shrimp recalled by the Canadian Food Inspection Agency can return it and get a refund.

The Canadian Food Inspection Agency warned the public on Friday not to eat breaded shrimp or coconut shrimp sold by M&M Meat Shops across Canada.

CFIA says the product may be contaminated with nitrofurans, antimicrobial drugs which are banned for use in Canada in food producing animals. CFIA spokesman Shashi Kulkarni told CBC News food contaminated with nitrofurans may cause cancer, but only if eaten over a long period of time.

"Any chemical really that is known to be carcinogen, one eating just a little amount here, little amount there, is not what the risk is about," said Kulkarni.

"It's the cumulative risk of the ingestion of these chemicals that can certainly predispose an individual to cancer."

Kulkarni said the shrimp came from Ecuador, and CFIA discovered the contamination during its regular food testing.

The Port Dover, Ont.-based manufacturer, Henry H. Misner Ltd., has voluntarily recalled the products.

The Charlottetown M&M Meat Shop will take back any 400 gram-packages of the breaded or coconut shrimp and provide a refund.
