CDC Continues Investigation of Salmonella Reading Outbreak


Following traceback investigations applying whole genome sequencing, the Centers for Disease Control has demonstrated that some patients infected with Salmonella Reading acquired the pathogen from consuming improperly cooked ground turkey.


Jennie-O Turkey Store a subsidiary of Hormel Foods recalled 45 tons of ground turkey produced at the Barron, WI plant on November 15th.  A subsequent recall on December 21st was announced by the company for product processed at the Faribault, MN plant with the total amounting to approximately 80 tons of raw ground product.

Field investigations carried out by FSIS have disclosed Salmonella Reading in live turkeys and from plants suggesting that the problem is not restricted to Jennie-O.  As of December 18, 2016 216 cases have been confirmed from 38 states and the District of Columbia.  Illnesses commenced in late November 2017 and continued through December 6, 2018.  The hospitalization rate is 48 percent and one fatality was recorded in California.


Of 132 isolates from 61 patients and 21 live turkey samples, there was no evidence of antibiotic resistance. In a second batch of 80 isolates from patients and 97 isolates from turkey, environmental and food samples, the CDC National Antimicrobial Resistance Monitoring System laboratory identified genes coding for resistance to a wide range of antibiotics.


Additional epidemiologic components associated with the outbreak involved apparent infection from handling presumably contaminated pet food containing raw ground turkey.  In addition four of the108 cases investigated worked in a facility that either raises or processes turkeys.
