It turns out that many raccoons are infected with a parasitic roundworm, Baylisascaris procyonis. By “many,” I mean that it is estimated that some 72 to 100 PERCENT of all raccoons have this worm inside them and are pooping out its eggs. If you were to accidentally inhale such eggs, say, by sending them into the air by sweeping a pile of old dry raccoon feces off your porch, they will hatch into larvae inside your body.
