Check your freezers.

And if you find any President’s Choice fresh beef products, look carefully at the best-before dates.

That’s because a wide selection of PC-branded fresh beef, imported from JBS Swift Beef Co. in Greeley, Colo., may be contaminated with E. coli bacteria, known to cause gastrointestinal distress and, in extreme cases, death.

The Canadian Food Inspection Agency has ordered a recall for the suspect products, which carry “best-before” dates of April 29 through June 16. There have been no reported illnesses here.

In Ontario, the items were sold at Cash & Carry, Real Canadian Wholesale Club, Dominion, Extra Foods, Fortinos, Freshmart, Loblaws, No Frills, Real Canadian Superstore, Loblaw Superstore, Valu-mart, Your Independent Grocer, Zehrs and Westfair.

As well, four- to five-pound packs of Beef Knuckle Roast sold between April 30 to June 10 at Sue’s Market in Richmond Hill are also affected by the recall.

The full recall list is available at www.inspection.
