For the second time in recent months, health officials are warning that certain frozen beef burgers sold in British Columbia may be contaminated with E. coli bacteria.

The Canadian Food Inspection Agency is warning the public not to consume some brands of The Gourmet Meat Shoppe and The Butcher's Cut brands of Frozen Beef Burgers because of a bacteria risk.

The products were distributed in B.C., Ontario, Manitoba, Saskatchewan and Alberta, and sold at Safeway stores. They have a best before date of Aug. 14, 2013.

The meat was produced at Cardinal Meat Specialists in Ontario.

The CFIA says the recall is the result of E. coli testing related to an ongoing food safety investigation at a facility which produces the meat. Testing will continue to see if any other products are affected.

This isn’t the first time Cardinal has been the subject of a recall.

Last fall, government officials linked an E. coli outbreak to a batch of Butcher’s Choice beef brand burgers sold nationwide.

Food contaminated with E. coli O157:H7 bacteria may not smell or look spoiled but consuming the products can be potentially life-threatening.

Symptoms include severe abdominal pain and bloody diarrhea.
