Beef, pork, chicken and turkey have, thanks to their widespread availability, become mainstream proteins, taking up the vast majority of a retailer’s meat case or a restaurant’s menu. Everything else gets lumped into the category of “exotic” or “game” meats. That’s not necessarily a fair or accurate description, however.
Consider the case of bison. Bison meat has been feeding people on this continent for hundreds of years. It’s not very “exotic” when its use as a nutritious protein pre-dates the United States itself. Secondly, bison today isn’t hunted like venison. While bison have not been domesticated and remain wild animals, bison ranches dot the Western United States, providing the animals to supply a growing demand among American consumers. The bison industry is innovating and growing in its effort to make bison more of a mainstream meat.
