If you plan on eating hamburger for dinner, you better check the package. The E. Coli bacteria has been detected in ground beef that may have been sold at some Kroger Stores. Most of the E. Coli outbreaks, like this one are associated with fecal contaminated meats in slaughterhouses. The sell by date expired more than a week ago, so the meat shouldn’t be in shelves: but consumers are urged to check their freezers. To make sure your meat is safe, Kroger says consumers should check for a sell by date of August 19th. All packages will have a U-S-D-A stamp identifying the producer as number 4-1-0. If consumers have any questions or concerns call 1-800-632-6900.
