Minnesota state health and agriculture officials are investigating seven cases of E. coli O157:H7 infection in residents associated with eating ground beef purchased from Lunds or Byerly’s stores.

The cases include two children and five adults. Three of the cases were hospitalized, but all have been discharged.  Marler Clark has been contacted by victims of this outbreak.

According to the Minnesota Department of Health, “The stores currently involved include Byerly’s St. Louis Park, Byerly’s Minnetonka, Byerly’s Chanhassen and Lunds Edina. However, we can’t be certain that meat from other stores is not involved, since all of the beef used for ground beef for Lunds and Byerly’s stores comes from a single processing facility,” said Heidi Kassenborg, Acting Director of the Dairy and Food Inspection Division of the Minnesota Department of Agriculture.

Ground beef that was purchased after April 7 from a Lunds or Byerly’s store, whether still in the refrigerator or freezer, should not be used, but should be discarded or returned to the store, officials said.
