Which agency conducts quality grading inspections for food products?

The United States Department of Agriculture (USDA) is responsible for conducting quality grading inspections for food products. This agency is tasked with ensuring that agricultural products meet specific standards of quality, safety, and labeling. The USDA's grading system assesses products such as meat, poultry, eggs, and dairy to indicate their quality levels, which helps consumers make informed choices about the food they purchase.

In contrast, the Centers for Disease Control and Prevention (CDC) focuses primarily on public health and safety, monitoring disease outbreaks rather than directly inspecting food products for quality. The Food and Drug Administration (FDA) is involved in regulating food safety and labeling but does not conduct quality grading inspections in the same way the USDA does. The Occupational Safety and Health Administration (OSHA), on the other hand, is concerned with workplace safety and health regulations rather than food quality or safety inspections. Thus, the role of the USDA is specifically tailored to the grading and inspection of food products, making it the correct choice in this context.
