Tapeworms in humans aren't an odd sight, unless of course they measure in at 16ft. 45-year-old Chen from Guangxi, south China who loves to eat raw beef and fish complained of stomach problems to doctors.
Tests were carried out by his city's Gastroenterology department which revealed the tapeworm and even then, it took five days to extract.
Doctors determined the parasite had come from contaminated raw food and studied it to discover how it grew so long in its host. Tapeworms - or taenia saginata as they are known scientifically - has eggs which hatch in cattle and are carried through the body by the animal's circulatory system. The egges hatch three months after human consumption and develop into adults in the small intestine which according to scientists have a life expectancy of 60years. To think someone could carry it around almost all their life.
