An E. coli outbreak that began in Michigan and Ohio now includes one case each in Kentucky, Indiana and New York. The cases are thought to be related to ground beef that was recalled by the Kroger company this month.The ground beef in question was sold at Kroger stores in Michigan and Ohio, but the recall was expanded to other states as a precaution. The case in Kentucky was reported near the Ohio border.Kentucky epidemiologist Dr. Kraig Humbaugh says the Kentucky patient had eaten beef, but that’s the only evidence of the infection in the Commonwealth.“At this point we haven’t had any positive tests in the food itself here in Kentucky," he says.So far, 44 E. coli cases have been confirmed, most of them in Michigan and Ohio. There have been no deaths from the illness.
