In October 2018 the CDC announced an outbreak of Salmonella Infantis infections associated with raw chicken products from a variety of sources. In interviews, ill people reported eating different types and brands of chicken products. The outbreak strain was identified in samples taken from raw chicken pet food, raw chicken products and live chickens.

In interviews, ill people answered questions about foods they ate and other exposures in the week before they became ill. Of 54 people interviewed, 48 (89%) people interviewed reported preparing or eating chicken products that were purchased raw, including ground chicken, chicken pieces and whole chicken. Ill people reported buying many different brands of raw chicken products from multiple stores. Also, one person got sick after pets in their home ate raw ground chicken pet food. Another ill person lived with someone who works in a facility that raises or processes chickens.

Twenty-nine states reported 92 cases. Twenty one people were hospitalized. There were no deaths. Illnesses started from January 19, 2018 to September 9, 2018.
