Thanks for the National Geographic link about armadillo consumption and leprosy occurrence in Brazil.
One phrase stood out for me: “...armadillo liver ceviche, a mixture of raw meat and onions.”
Also, the article talked about a high incidence of leprosy antibodies in both people and armadillos. I wonder (didn’t find it in the article) whether the leprosy antibodies indicate successful resistance, or are more indicative of early or latent infection which will tend to get out of hand over time.
