Armadillos are natural carriers of Mycobacterium leprae. If memory serves from having lived down south, I think it's the nine banded armadillos that carry it. It's present primarily on their feet.
I don't remember ever hearing anything about eating armadillos, but we were always cautioned against handling them.
We used to call them "nature's speed bumps" because they were often seen right before, or after, getting hit by a car. They jump, too, when scared. If they jumped at just the right time they'd slide up the hood and ramp off the windshield. Some of them got pretty decent air time before their rather abrupt landing.
