Centers for Disease Control and Prevention, several states, and the U.S. Department of Agriculture’s Food Safety and Inspection Service are investigating a multistate outbreak of Shiga toxin-producing Escherichia coli O103 infections. Preliminary information suggests that ground beef is the source of this outbreak. This investigation is ongoing, reports CDC.

A total of 109 people infected with the outbreak strain of E. coli O103 have been reported from six states — Indiana, Ohio, Kentucky, Virginia, Tennessee and Georgia. Seventeen people have been hospitalized. Ill people in this outbreak report eating ground beef at home and in restaurants.
