The US Centers for Disease Control and Prevention (CDC) is collaborating with state health officials in an investigation of a multistate outbreak of E. coli O157:H7 infection that is linked to ground beef produced by a Michigan firm.
The outbreak has affected at least 11 people in Massachusetts, Michigan, Missouri and Ohio with onset of illness between April 22 and May 2. Six of the cases have required hospital treatment, but none have developed haemolytic uremic syndrome (HUS) and no deaths have been reported.
Epidemiological and trace-back investigations have identified ground beef products supplied by the Wolverine Packing Company, of Detroit Michigan, as the likely source of the outbreak.
The company is now recalling approximately 1.8 million pounds of ground beef products produced between 31 March and 18 April 2014 that may be contaminated. The recalled beef was distributed nationwide for restaurant and retail use and packs are labelled with the establishment number “EST. 2574B” and a production date code between “03 31 14” and “04 18 14”.
