Despite the fact that it sounds incredibly gross and cruel, it's actually better for you to eat them in this way. That's because dead oysters which are eaten raw can contain bacteria that is harmful to humans and can make us ill - with symptoms including a fever, vomiting and diarrhoea.
Do oysters poop? Oysters are filter feeders, and take in all different types of particles from the water column. As oysters digest food, waste collects in a cavity inside their shell. Besides to actual waste, items called pseudofaeces also collect there.
