I believe its macellaio
Yes, it is legal to do so. But the butcher is has an option to say no. Umm just the other day there was a news report on this topic they claimed it was illegal to eat horse meat in the United States....
meat
It could either mean a dealer in meat, a person who slaughters or dresses animals for food, a brutal murderer or to bungle.
a butcher is someone who prepares various meats and other related goods for sale
