Which body does not have the authority to require the recall of a manufactured product?

NIOSH, the National Institute for Occupational Safety and Health, focuses primarily on conducting research and making recommendations to prevent work-related injuries and illnesses. While NIOSH plays an important role in occupational safety and health, it does not have the enforcement authority to require the recall of manufactured products.

In contrast, the other bodies mentioned—CPSC (Consumer Product Safety Commission), FDA (Food and Drug Administration), and EPA (Environmental Protection Agency)—do have the legal authority to mandate recalls. The CPSC oversees consumer products to ensure safety and can compel recalls of hazardous products. The FDA regulates food and medications and has the power to recall unsafe or mislabeled food products and drugs. The EPA addresses environmental concerns and can require the recall of pollutants or hazardous chemicals under relevant laws. Thus, NIOSH's role is more about recommendations and research rather than enforcement actions like product recalls.
