A man in China, who loved eating raw beef, was found to have a 20-foot-long tapeworm inside his stomach.
The 38-year-old man had the parasite for two years and had been suffering from severe stomach pain, vomiting, anorexia and weight loss. He underwent several diagnosis and received treatments for abdominal pain and chronic anemia which showed no improvement.
Later he approached Renmin Hospital in Shiyan, where he told Dr. Jian Li that he had a habit of eating raw beef. Microscopic examination of his stool showed an embryonated egg containing an oncosphere.
The tapeworm was found to be Taenia saginata, a beef tapeworm. Humans are the only definitive hosts who can become infected with T. saginata by consuming raw or inadequately cooked beef.
After 3three months, he got completely recovered. The case report was published in The New England Journal of Medicine.
