Update: On September 18, after this article was published, Canadian Food Inspection Agency released an expanded list of retailers to which the recalled ground beef from XL Foods was sold. The updated list can be found here, or at the link to CFIA’s website below. Ground beef products sold at major grocery chains across Canada are being recalled because they may be contaminated with E. coli. The Canadian Food Inspection Agency announced Monday that XL Foods of Alberta was recalling various ground beef products such as patties, meatballs and meatloaf because the ground beef from which they were made may contain E. coli. The majority of the affected foods were sold to retail stores in Alberta, British Columbia, Saskatchewan, Manitoba and Ontario, but Costco’s Kirkland Signature brand was sold at stores nationwide. Other companies who carry the affected meats include Safeway, Walmart and Calalhoo Meats. Products subject to the recall include ground beef, burger patties, ground chuck, ground sirloin patties, stuffed peppers, meatballs, beef sliders, meatloaf, cheddar cheese patties and ground beef tubes. The affected ground beef products were packaged between August 29 and September 15, 2012 and are marked with “best by” or “freeze by” dates of September 9 through September 13, according to CFIA. CFIA said Monday that the recall is part of an ongoing food safety investigation and that it is working to verify all involved products and determine whether any more may need to be recalled. No illnesses have been related to consumption of any of the affected foods to date, says CFIA. Consumers who have purchased the recalled meat should return it to its point of purchase.
