Salmonella. When the Brazilian tortoise is kept as a pet, the biggest harm to the human body is the Salmonella bacteria it carries. The Brazilian tortoise carries 85% Salmonella, especially young turtles, and carries more Salmonella. These bacteria have been proved to be spread to humans and cause related diseases. Like any pet, keeping Brazilian tortoises needs to pay attention to hygiene, regularly disinfect pet breeding places and clean pets, and don't let pets enter the family food area.
