Are raw common garden-snails poisonous when eaten by a human?

They Carry A Small Parasite That Attack Your Brain And Shut Down Your Body If Not Noticed Right Away Of Eating It. It Can Kill U Under 1 Week. So No They Are Not Poisonous But Carry A Parasite That Kills You. If Your Going To Eat Them Cook Them VERYCarefully. I Hope That Answered Your Questions
