Here's why:
* Water buffalo meat is often marketed as "buffalo" or "beef". This is because water buffalo are related to cattle, and their meat has a similar taste and texture.
* American bison meat is generally called "bison" or "buffalo". However, "buffalo" can be used to refer to both water buffalo and bison, which can be confusing.
It's important to note that "buffalo" can be used as a general term for the meat of both water buffalo and American bison, but it's often used more specifically for water buffalo meat.
If you're buying buffalo meat, it's important to ask the butcher or retailer what kind of animal the meat came from.
