The United States Department of Agriculture (USDA) has implemented a grading system to ensure consumers know the quality and characteristics of the beef they purchase. This system is entirely voluntary and producers pay a fee to get their product graded. This system helps consumers, retailers, and producers understand and communicate the quality of beef products. The grading primarily focuses on quality grades for tenderness, juiciness, and mainly marbling; and yield grades for the amount of usable lean meat on the carcass.
