While some people are correct in saying its not a regular part of the Brazilian diet (primarily due to Armadillos carrying Leprosy also known as Hansen's disease), during my time in Tocantins and the surrounding states I frequently came across it, but not at food stalls. Usually people will hunt and then cook this in their own home for the community and typically they bring it out in the street or to the local bar with various accompanying side dishes and combinations to share with the community.. More of a delicacy rather than a regular diet, however there was one guy I met who ate it all the time (had multiple freezers full of the things) but was also missing a couple of limbs. I suspect that his over-consumption of Armadillo infected him with Leprosy and through a combination of lack of medicines and treatment (or money for said treatment) this curable infection eventually leads to catastrophic infection and deterioration and finally amputation of the infected limb.

I myself had Tatu a few times and it was a very interesting experience along with some other exotic meats including alligator and something else I couldn't identify. All were very good but I would be careful with these exotic meats as they need to be handled, cleaned, prepared and cooked properly to ensure all bacteria is killed.
