Bats in the belfry, no, but bats in the salad yes. A walmart accidentally sold a salad with a dead bat in it. There was insufficient evidence to determine how contagious the dead bat was, according to reports. At least refunds are available if there was more than one contaminated container.

It's sad when washing, filtering, and observing do not prevent adulterated foods from getting into the food supply.
