Everyone knows that a tapeworm infestation is really not ok. But what the majority of people do not know is that the tapeworm is a deadly killer: so much so that it kills around 2000 people around the world per year! In the Western world tapeworm infestations are pretty rare but in under-developed countries, they can be quite common.
These infections occur when people consume undercooked meat or fish that is contaminated with tapeworm. Once ingested, the tapeworm hooks on to the intestinal wall and can then grow up to 9 meters long until it can eventually kill you.
