A federal law bans the sale and distribution of turtles with shells less than 4 inches long as pets because they have caused many illnesses, especially in young children. Despite the ban, these turtles are sometimes still sold illegally online, at stores, flea markets, and roadside stands.
Pet turtles of any size can carry Salmonella germs in their droppings even if they look healthy and clean. These germs can easily spread to their bodies, tank water, and anything in the area where they live and roam.
You can get sick from touching a turtle or anything in its environment and then touching your mouth or food with unwashed hands and swallowing Salmonella germs.
