A total of 16 persons infected with the outbreak strain of Salmonella Typhimurium have been reported from 7 states. The number of ill persons identified in each state is as follows: HI (1), KY (1), MA (1), ME (4), NH (4), NY (4), and VT (1). Among persons for whom information is available, illnesses began on or after October 8, 2011. Ill persons range in age from 1 year to 79 years old, with a median age of 45 years old. Fifty percent are male. Among the 13 ill persons with available information, 7 (54%) have been hospitalized. No deaths have been reported.
Preliminary testing shows that the outbreak strain of Salmonella Typhimurium is resistant to several commonly prescribed antibiotics. This antibiotic resistance may be associated with an increase in the risk of hospitalization or possible treatment failure in infected individuals.
