Salmonella Pomona, a highly pathogenic serotype, can cause severe human salmonellosis, especially in children. Turtles and other reptiles are reservoirs for S. Pomona, and these cold-blooded animals remain a source of human Salmonella infections. Since the 1980s, this serotype has become a significant public health concern because of the increasing number of cases of S. Pomona infection in humans. To date, outbreaks of Salmonella Pomona infection in humans have mainly occurred in the United States, with some in other countries (e.g. Belgium, Germany, Canada), and most of the infections in humans were associated with turtles and other reptiles. In China, S. Pomona was first isolated from the feces of an infant in Shanghai in 2000, and two further cases of S. Pomona infection in humans were later found in Guangzhou. No one knew the source of S. Pomona in China. In this study, for the first time we isolated S. Pomona from free-living exotic red-eared sliders in the wild in China. Salmonella serotype (S. Pomona) was isolated from 16 turtle samples. The total carrying rate of S. Pomona in the collected red-eared sliders was 39% (n = 41) overall: 40% (n = 25) in juveniles and 38% (n = 16) in adult turtles. This study suggests that the widespread exotic red-eared sliders may impact on public health and ecosystems of China by transmitting S. Pomona. Additional steps should be considered by the governments and public health agencies to prevent the risk of turtle-associated Salmonella infections in humans in China.
