Skyline Provisions, Inc., a Harvey, Ill., establishment, is recalling 1,029 pounds of beef products contaminated with E. coli O157:H7, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) announced today.

Produced between April 15-25, 2015, the following products are subject to recall:

17 ½ boxes of Aurora Packers Intact Beef Round Flats

On April 15, 2015, Skyline sold the product under their D&S label (Establishment number: 19300), ground and tested one and a half cases of the product. On April 21, 2015, these products were found positive for E. coli O157:H7. The remaining intact, products were sold to Jack & Pat’s Old Fashioned Market in Chicago Ridge, Ill., where the product was ground and sold in various amounts of ground chuck patties, ground chuck, ground round, sirloin patties and porter house patties.

FSIS discovered the problem during a routine sampling program. Neither FSIS nor the company received any reports of illnesses associated with consumption of this product. FSIS and the company are concerned that some product may have been sold and stored in consumers’ freezers.

E. coli O157:H7 is a potentially deadly bacterium that can cause dehydration, bloody diarrhea and abdominal cramps 2–8 days (3–4 days, on average) after exposure the organism. While most people recover within a week, some develop a type of kidney failure called hemolytic uremic syndrome (HUS). This condition can occur among persons of any age but is most common in children under 5-years old and older adults. It is marked by easy bruising, pallor, and decreased urine output. Persons who experience these symptoms should seek emergency medical care immediately.
