VANCOUVER (CBC) - Anyone planning to toss some hamburgers on the barbeque over the long weekend is being warned to check the label.

The Canada Food Inspection Agency issued a warning on Thursday that some frozen beef and bison burger patties sold at a number of meat stores under various brand names across B.C. may contain dangerous E. coli bacteria.

British Columbia consumers are being warned not to eat ground beef distributed by Trimpac Meat Distributors of Vancouver because it may be contaminated.

The Canadian Food Inspection Agency said six retailers sold the ground beef between February and May.

The supplier and the retailers recalled the meat. The CFIA warns consumers to check the date and source of the products before using them. So far, there have been no reported illnesses associated with the products.

Food contaminated with E. coli may not look or smell spoiled, but consumption may cause serious and potentially life-threatening illnesses. Symptoms include severe abdominal pain and bloody diarrhea, and in severe cases people may die, the CFIA said.

The recall is limited to products listed below:
