The lady identified as Mrs Li, after noticing unusual fluids in her stool, went to see a doctor in Xiamen, China. She was diagnosed with teniasis, which pretty much means she had an intestinal tapeworm infection.
How does the tapeworm get in the beef you ask? Well the parasite can lay its eggs in animal cysts and if not properly cooked, after a human being eats it, the eggs can hatch and grow in the human gut. OMG Gross! Gross! Gross. Yuck!.
Mrs Li was treated with traditional Chinese medicine and was able to pass the worm out you see above. #Faints. This kind of story just makes me wanna pukesieees!
