The Centers for Disease Control and Prevention (CDC), multiple states, and the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (USDA-APHIS) are investigating 10 separate multistate outbreaks of Salmonella infections in people who had contact with live poultry in backyard flocks. Since June 1, 2017, 418 more ill people have been reported. The most recent illness began on June 20, 2017.
These outbreaks are caused by several DNA fingerprints of different Salmonella bacteria: Salmonella Braenderup, Salmonella Enteritidis, Salmonella Hadar, Salmonella I 4,,12:i-, Salmonella Indiana, Salmonella Infantis, Salmonella Litchfield, Salmonella Mbandaka, Salmonella Muenchen, Salmonella Typhimurium.
The outbreak strains of Salmonella have infected a reported 790 people in 48 states and the District of Columbia.
Illnesses started on dates ranging from January 4, 2017 to June 20, 2017.
Of 580 people with available information, 174 ill people have been hospitalized. No deaths have been reported.
Epidemiologic, traceback, and laboratory findings link the 10 outbreaks to contact with live poultry, such as chicks and ducklings, from multiple hatcheries.
In interviews, 409 (74%) of 553 ill people reported contact with live poultry in the week before illness started.
Contact with live poultry or their environment can make people sick with Salmonella infections. Live poultry can be carrying Salmonella bacteria but appear healthy and clean, with no sign of illness.
