What is USDA Prime?
USDA Prime is a grade of beef, as graded in the United States. It is considered the highest grade of domestic beef by the USDA scale, and as such tends to be the most expensive. Beef grade is only one way to label beef, and in recent years there has been a shift from labels such as USDA Prime to labels that designate a particular breed of cattle, a particular style of raising, or a particular locale where the cattle was raised.
