Multistate outbreak of Salmonella infections linked to raw turkey products

20 July, 2018

Ninety people infected with the outbreak strain of Salmonella Reading have been reported from 26 states.
Forty people have been hospitalized, and no deaths have been reported. 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. Two ill people lived in a household 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. A single, common supplier of raw turkey products or of live turkeys has not been identified. 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. 
Salmonella enterica subsp. enterica serovar Reading (antigenic formula 1,4,[5],12:f,g:[1,2]) is a serovar of the O:4 (B) serogroup. It has been implicated in foodborne illness, as well as a breast abscess, and a case of osteomyelitis. Poultry and swine are the implicated reservoirs for serovar Reading, and it has been the cause of death in turkey poults*.
Kauffman (1941) reports that Salmonella reading was first isolated in 1916 by Schütze from a water supply in Reading, England, and reported in the literature in 1920.
