As with many other reptile species, this species frequently has bacteria living naturally in its guts that can be harmful to humans (they are normal members of the gut flora of the reptiles). In particular, these turtles can be source of bacteria in the genus Salmonella. This is why it is illegal to sell small turtles as pets in the United States. Anyone keeping and handling turtles should be careful to maintain hygienic methods and wash their hands after handling.
