Multistate Outbreak of Multidrug-Resistant Salmonella Heidelberg Infections –CDC
- CDC, several states, and the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (USDA-APHIS) are investigating a multistate outbreak of multidrug-resistant Salmonella Heidelberg infections.
- Twenty-one people infected with the outbreak strain of Salmonella Heidelberg have been reported from 8 states.
- Illness onset dates range from January 11, 2016 to October 24, 2016.
- Eight ill people were hospitalized, and no deaths have been reported.
- Epidemiologic, traceback, and laboratory findings have linked this outbreak to contact with dairy bull calves purchased from livestock markets in Wisconsin. Dairy bull calves are young, male cattle that may be raised for meat.
- The Wisconsin State Laboratory of Hygiene and CDC’s National Antimicrobial Resistance Monitoring System (NARMS) laboratory conducted antibiotic-resistance testing on clinical isolates collected from ill people infected with an outbreak strain of Salmonella Heidelberg.
- All isolates were multidrug resistant.
- Antibiotic resistance may be associated with increased risk of hospitalization, development of a bloodstream infection, or treatment failure in patients.
