According to the CDC, since the last update on December 21, 2018, 63 ill people from 24 states, and the District of Columbia, have been added to this investigation.

As of February 13, 2019, 279 people infected with the outbreak strain of Salmonella Reading have been reported from 41 states and the District of Columbia. 107 people have been hospitalized. One death has been reported from California.

Epidemiologic and laboratory evidence indicates that raw turkey products from a variety of sources are contaminated with Salmonella Reading and are making people sick. In interviews, ill people report eating different types and brands of turkey products purchased from many different locations. Four ill people lived in households where raw turkey pet food was fed to pets. The outbreak strain has been identified in samples taken from raw turkey pet food, raw turkey products, and live turkeys.

Several turkey products have been recalled because they might have been contaminated with Salmonella. Please see the list of recalled items below. A single, common supplier of raw turkey products or of live turkeys has not been identified that could account for the whole outbreak.

The Public Health Agency of Canada has identified ill people in Canada infected with Salmonella Reading bacteria with the same DNA fingerprint.  As of January 31, 2019, there have been 72 confirmed cases of Salmonella Reading illness investigated in the following provinces and territories: British Columbia (20), Alberta (24), Saskatchewan (6), Manitoba (13), Ontario (6), New Brunswick (1), Northwest Territories (1), and Nunavut (1). Individuals became sick between April 2017 and early January 2019. Eighteen individuals have been hospitalized. One individual has died. Individuals who became ill are between 0 and 96 years of age. The majority of cases (55%) are female.

The outbreak strain of Salmonella Reading is present in live turkeys and in many types of raw turkey products, indicating it might be widespread in the turkey industry. CDC and USDA-FSIS have shared this information with representatives from the turkey industry and requested that they take steps to reduce Salmonella contamination.
