Notes from the field: outbreak of salmonellosis associated with pet turtle exposures--United States, 2011.

CDC is collaborating with the Pennsylvania State Health Department in an ongoing investigation of an outbreak of human Salmonella enterica serotype Paratyphi B var. L (+) tartrate + infections associated with pet turtle exposures. Turtles have long been recognized as sources of human Salmonella infections and are a particular risk to young children. Although the sale or distribution of small turtles (those with carapace lengths <4 inches [<10.2 cm]) has been prohibited in the United States since 1975 (with exceptions for scientific or educational purposes), they are still available for illegal purchase through transient vendors on the street, at flea markets, and at fairs.
