CDC collaborated with public health and regulatory officials in several states and the U.S. Department of Agriculture Food Safety and Inspection Service (USDA-FSIS) to investigate a multistate outbreak of Shiga toxin-producing Escherichia coli O157:H7 (STEC O157:H7) infections.
Eleven people infected with the outbreak strain of STEC O157:H7 were reported from five states. A list of the states and the number of cases in each can be found on the Case Count Map page.
