Final answer:
The USDA grade of beef not typically purchased for general foodservice use is 'Commercial'. This grade, as well as others like Utility, Cutter, and Canner, is often used for processed products rather than for direct service in restaurants or supermarkets.
Step-by-step explanation:
The USDA grade of beef NOT purchased for general foodservice use is D. Commercial. In the United States, the Department of Agriculture (USDA) grades beef at several levels of quality based on factors like marbling, age, and color. The highest grades, such as Prime and Choice, are often used in restaurants and supermarkets, while Select is a lower quality but still widely available. Commercial grade, along with other lower grades such as Utility, Cutter, and Canner, are typically not used in foodservice; instead, they might be processed into ground beef or used in products where the tenderness and flavor of the meat are not as critical, like canned goods or pet foods.
