Salmonella Typhimurium, Water Frogs and an “Unnamed California Frog Breeder”

In December 2009, the CDC reported 85 individuals infected with Salmonella Typhimurium in 31 states: Alabama (1), Arizona (1), California (5), Colorado (4), Florida (1), Georgia (1), Idaho (1), Illinois (5), Indiana (1), Kentucky (1), Louisiana (1), Massachusetts (3), Maryland (3), Michigan (4), Minnesota (1), Missouri (4), Mississippi (1), Nebraska (1), New Jersey (2), New Mexico (1), New York (2), Nevada (1), Ohio (2), Pennsylvania (4), South Dakota (3), Tennessee (2), Texas (4), Utah (14), Virginia (3), Washington (7) and Wisconsin (1). The Salmonella Typhimurium outbreak was linked to water frogs linked to an unnamed California frog breeder.

Today, the CDC announced a multistate outbreak of human Salmonella Typhimurium infections associated with contact with water frogs, such as African dwarf frogs. As of April 5, 2011, a total of 217 individuals (which includes the 85 above) infected with the outbreak strain of Salmonella Typhimurium have been reported from 41 states since April 1, 2009. The number of ill person identified in each state is as follows: Alaska (5), Alabama (2), Arizona (10), California (17), Colorado (12), Connecticut (3), Florida (1), Georgia (4), Idaho (4), Illinois (8), Indiana (1), Kansas (2), Kentucky (4), Louisiana (2), Massachusetts (6), Maryland (5), Michigan (6), Minnesota (1), Missouri (5), Mississippi (1), Montana (2), North Carolina (1), Nebraska (2), New Hampshire (3), New Jersey (3), New Mexico (2), Nevada (3), New York (7), Ohio (7), Oklahoma (1), Oregon (5), Pennsylvania (14), South Dakota (3), Tennessee (4), Texas (4), Utah (18), Virginia (11), Vermont (1), Washington (23), Wisconsin (3), and West Virginia (1).

Infected individuals range in age from less than 1 year old to 73 years old. Seventy-one percent of patients are younger than 10 years old, and the median age is 5 years old. Fifty-one percent of patients are female. Among ill persons, 34% were hospitalized. No deaths have been reported. Findings of traceback investigations identified a single water frog breeder in California as the source of African dwarf frogs associated with human infections. This frog breeding facility was first identified as the source of African dwarf frogs associated with human infections in 2010.
