Atlanta — An E. coli outbreak traced to recalled beef in Michigan and Ohio has spawned cases in three other states, U.S. health officials said Tuesday.

New York, Kentucky and Indiana each have one lab-confirmed case of a bacterial infection that matches the 41 previously reported cases, according to the Centers for Disease Control and Prevention.

The outbreak has been traced to beef sold in Kroger supermarkets in Michigan and Ohio. The Kroger Co. last month recalled ground beef sold in Michigan and Ohio stores, then this month expanded it to include other states. Nebraska Beef Ltd. supplied the meat, ultimately recalling 5.3 million pounds of beef.

The Kentucky patient lives near Ohio, but the New York and Indiana patients did not travel to either of the states where the outbreak began, said Mark Sotir, a CDC investigator working on the outbreak.

All 44 illnesses in the outbreak are attributed to the same type of E. coli, one that causes a potentially deadly bacterial infection. The illnesses began between May 30 and June 24. CDC officials say 21 of the victims have been hospitalized and one developed kidney failure, but no one has died.
