More than 28,000 pounds of ground beef, including packages sold at some Walmart stores, are being recalled for possible E. coli contamination.
The products were sold at select Walmart, Kroger, Albertsons and WinCo Foods stores under store brand labels.
Walmart posted a 13-page list of the store locations that sold the recalled meat on its website Friday, which includes stores in the seven states as well as locations in Alaska, Colorado, Hawaii, Idaho and Montana.
Albertsons Companies said in a notice on its website that affected "Signature Farms Ground Beef 93% Lean/7% Fat" products were sold in Albertsons and Safeway stores in Oregon and Washington.
E. coli can cause dehydration, bloody diarrhea and abdominal cramps three to four days after exposure – and potentially kidney failure in children under 5 years old and in older adults.
The USDA classified the announcement as a "Class I" recall, which it defines as a "health hazard situation where there is a reasonable probability that the use of the product will cause serious, adverse health consequences or death.".
