Heads up if you’ve purchased any ShopRite hamburger patties this year:

The manufacturer of those patties has issued a voluntary recall on some products because of possible E. coli contamination to the food.

Officials say that certain beef products produced between May 27 and May 30 may be contaminated with E. coli.  The food, which was actually produced in Canada by Ryding-Regency Meat Packers, was found to have possibly been contaminated after an inspection from the Canadian Food Inspection Agency. The USDA confirmed the news on Thursday (October 17).

The ShopRite label is just one of the brands that could be affected by the recall. Other brands included Devanco Foods, Kronos, and Landis Brands products. For more information on which specific labels from those manufacturers are involved in the recall, click here.

In the meantime, here’s the exact list of ShopRite products which have been voluntarily recalled:

  • 8-lb. cardboard box packages containing bulk plastic-wrapped raw frozen ground beef patties labeled “ShopRite 100% PURE QUARTER POUND Ground Beef Hamburgers” and a sell-by date of 060720.
  • 3-lb. cardboard box packages containing plastic wrapped raw frozen ground beef patties labeled “ShopRite 100% PURE Ground Beef Hamburgers” and a sell by date of 060720.

The product should be thrown away or returned to your local grocer.

CDC Officials say that E. coli symptoms develop about 3 to 4 days after exposure, but the exact timeline vary. The signs of infection can vary for each person, but the symptoms often include severe stomach cramps, diarrhea (often bloody), and vomiting.

E. coli can be prevented by thorough hand washing after using the bathroom or changing a diaper, before and after food preparation, and after contact with animals, according to the CDC.
