The USDA’s Food Safety and Inspection Service says stores in at least 12 states may have received beef contaminated with E. coli O157:H7.

The service announced this week that 1.8 million pounds of ground beef products were being recalled because they could be contaminated. The federal agency has since named businesses that may have received the tainted products.

They include:

• Gordon Food Service Marketplace stores in Florida, Illinois, Indiana, Kentucky, Michigan, Ohio, Pennsylvania, Tennessee and Wisconsin

• Giorgio’s Italian Delicatessen in Stuart, Florida

• Blairsville Seafood Market in Blairsville, Georgia

• M Sixty Six General Store in Orleans, Michigan

• Bronson’s Super Valu in Beulah, North Dakota

• Jason’s Super Foods in New Town, North Dakota

• Buchtel Food Mart in Buchtel, Ohio

• Quick Stop in Erwin, Tennessee

• Virginia Market in Maynardville, Tennessee

• Barger Foods in Nashville, Tennessee

• Virginia Heights Travel Store in Wytheville, Virginia

A representative for the U.S. Department of Agriculture said the meat is being removed from store shelves. But consumers should return or throw out meat that has the code EST.2574B and a production date between March 31 and April 18, 2014.

The ground beef is sold under a variety of labels, according to the USDA, but comes from Wolverine Packing Co. in Detroit.

Eleven people across four states are suspected to have been sickened by the product, according to the USDA, which learned about the first such illnesses on May 8. Ten of those people were sickened after eating at restaurants that received contaminated meat.
