Taenia saginata is a parasitic tapeworm that infects cattle and is commonly known as beef tapeworm. Some synonyms for taenia saginata include T. medullaris, Taenia nana, Taenia solium, and Taenia crassiceps. Beef tapeworm infestation is usually asymptomatic, but when symptoms occur, they can be alarming, such as abdominal pain, diarrhea, and weight loss. Taenia saginata can cause severe health problems in humans if ingested raw or undercooked beef containing the tapeworm's larvae. To prevent infestation, meat should be cooked at high temperatures, and one should always practice proper food hygiene and sanitation measures.
