Birds shit on the olives when they're still alive too. Olives grow outside. Outside is not a sterile environment. When I was working at a green bean processing plant years ago, my first job was picking non-bean objects out by hand. Usually the non-bean objects were sticks, but many times a day it was a dead snake or frog. That's just the nature of those harvesters. The beans get rinsed and nobody worries about it.
