The illness trichinosis, also known as trichinellosis, is caused by the parasite Trichinella spiralis. This is true. The infection occurs when someone eats undercooked meat, usually pork, containing Trichinella larvae. These larvae are released when the meat is digested and then mature into adult worms in the large intestine.
