Taenia saginata is a type of tapeworm that primarily infects cattle and can be transmitted to humans through undercooked beef. It is one of the largest tapeworms, reaching lengths of up to 25 meters (82 feet). In humans, it can cause a condition known as taeniasis, which may lead to digestive issues, though many infected individuals remain asymptomatic. The life cycle of Taenia saginata involves both cattle and humans. Cattle become infected by ingesting eggs from contaminated feed or water. Once inside the human host, the tapeworm attaches to the intestinal wall and can live for years, producing segments that are excreted in feces, continuing the cycle of infection.
