Cute as your pet iguana or backyard birds may be, they’re a potential source of salmonella infection. According to the CDC, direct contact with turtles, iguanas, and chickens has been linked to human infection. Again, children should always wash their hands thoroughly after touching or playing with these animals. Dogs and cats can also be carriers of Salmonella bacteria. Be sure to keep pet waste away from children and avoid letting your child give kisses to these pets.
