Doctors thought that Rosemary Alvarez of Phoenix had a brain tumor at the base of her brain stem. That is until they got her onto the operating table and discovered something even more unsightly… a parasitic worm named Taenia solium, also known as a pork tapeworm. And how did Mrs. Alvarez end up with a tapeworm nuzzled around her brain stem you might ask? By eating food tainted with the feces of a person infected with the pork tapeworm parasite. Yes, her food had traces of poo in it because someone didn’t wash their hands properly.

“It wasn’t that she had poor hygiene, she was just a victim,” said Rosemary’s neurosurgeon Dr. Peter Nakaji.

So the lesson to learn here kids is to wash your hands after you take a dump for fuck’s sake! Or Mother Nature is gonna give you the Carnivorous Brain Worms.
