Several different types of Salmonella bacteria have made people sick in these outbreaks: Salmonella Seftenberg, Salmonella Montevideo, Salmonella Infantis, Salmonella Enteritidis, Salmonella Indiana, and Salmonella Litchfield.
A total of 334 people were infected with the outbreak strains of Salmonella reported from 47 states.
Illnesses started from February 15, 2018 to August 10, 2018.
56 ill people were hospitalized, and no deaths were reported.
21% of ill people were children younger than 5 years.
Epidemiologic, traceback, and laboratory findings linked these outbreaks to contact with live poultry, such as chicks and ducklings, which came from multiple hatcheries.
In interviews, 132 (63%) of 211 ill people with information available reported contact with chicks or ducklings in the week before their illness started.
People reported obtaining chicks and ducklings from several sources, including feed supply stores, websites, hatcheries, and from relatives.
These outbreak investigations are over. CDC will continue to work with state public health partners to monitor for the occurrence of Salmonella infections associated with contact with live poultry in backyard flocks.
