Salmonella Infections linked to Exposure to Live Poultry

May 2, 2016

The Michigan Department of Health and Human Services (MDHHS) is reporting an increase in Salmonella infections, or salmonellosis, among people who have had contact with live baby poultry. Since March 2, 2016, 20 cases of salmonellosis have been reported throughout the state; these numbers are expected to rise. Six individuals (30%) were hospitalized. The predominant serotype is SalmonellaEnteritidis; however, other serotypes have also been observed. The age range of cases is less than 1 to 70 years with a median age of 15.5 years; 85% are female.

Local health departments (LHDs) are playing a critical role in this outbreak investigation. Investigators from several LHDs with salmonellosis cases have visited the feed and farm stores in their jurisdictions (Muskegon, Monroe, Delta-Menominee, and St Clair) where their cases purchased baby poultry to collect environmental samples for testing. These environmental samples have been tested at the MDHHS Bureau of Laboratories and a number of samples are positive for Salmonella; some match the outbreak strain. Testing is still in process. A traceback is underway to determine from which hatcheries the feed and farm stores received their poultry. The Centers for Disease Control and Prevention has been notified.

When LHDs identify a salmonellosis case who has exposure to live poultry (direct or indirect), please complete the ‘Poultry Exposure Questionnaire for Salmonella’ (link below) and upload the completed questionnaire to the MDSS case record or fax to MDHHS at 517-335-8263.
