What Is the Longest Tapeworm Taken Out of a Human?

Tapeworms can come from several different sources, such as pigs, fish and beef. It is estimated that over 20 million people worldwide are infected with a tapeworm. The largest variant of tapeworms can be found in whales and is, on average, over 100 feet in length. Tapeworms grow segments that contain a digestive system as well as a reproductive system. The last segment of a tapeworm only contains a reproductive system. It is this last segment that splits off in feces and carries the tapeworm eggs that infect other creatures.
