Salmonella Heidelberg

Salmonella bacteria can be found everywhere in the environment. Every year, the bacteria cause nearly one million food borne illnesses nationwide. In Wisconsin, Salmonella is a common cause of gastrointestinal illness and is reportable. Certain strains can be more harmful than others. The Wisconsin Department of Health Services (DHS) is assisting in investigating an outbreak of multi-drug resistant (MDR) Salmonella Heidelberg infections believed to have come from contact with dairy bull calves.

  • DHS has identified contact with dairy bull calves purchased in Wisconsin as the likely source of most  of the 2016 infections.
  • Nationwide, twenty-one people from 8 states have been infected with the outbreak strain of Salmonella Heidelberg during January 11, 2016 to October 24, 2016. Eight people were hospitalized, and no deaths have been reported.
