Final answer:
The 'Graded by USDA' seal on red meat indicates that the USDA has evaluated the meat for quality. The grading, such as Prime, Choice, and Select, reflects factors like marbling, tenderness, and flavor. It helps consumers make informed purchasing decisions.
Step-by-step explanation:
When you see "Graded by USDA" on a package of red meat, it means that the meat has been evaluated by the United States Department of Agriculture (USDA) for quality and consistency. This grading system is voluntary and is paid for by meat processors. The grades, such as Prime, Choice, and Select, are based on characteristics such as marbling (the amount of fat interspersed with lean meat), tenderness, and flavor. Choice and Prime are the highest-quality grades typically sold at retail, with Prime being superior. This grading process ensures that consumers can make informed decisions about the meat they purchase, and it reflects factors that can influence the taste and tenderness of the meat.
