Taenia solium is a parasite that can be found in pigs. This parasite can cause a disease called cysticercosis, which can be harmful to humans if they accidentally consume undercooked or raw infected pork. Pigs can become infected with the parasite by eating infected human feces, which contains the parasite's eggs. To avoid getting sick, it is important to cook pork thoroughly and to practice good hygiene, especially in areas where Taenia solium is common.
