USDA Beef Grades. Beef is graded for quality by U.S. Department of Agriculture (USDA) graders according to standards established by the USDA. Grades are based on the amount of marbling (flecks in fat within the lean) and the age of the animal.
Grading for quality means the evaluation of traits related to tenderness, juiciness, and flavor of meat; and, for poultry, a normal shape that is fully fleshed and meaty and free of defects. USDA grades are based on nationally uniform Federal standards of quality.he inspection and grading of meat and poultry are two separate programs within the U.S. Department of Agriculture (USDA). Inspection for wholesomeness is mandatory and is paid for with public funds. Grading for quality is voluntary, and the service is requested and paid for by meat and poultry producers/processors.
