What registration must be found on pesticide and disinfectant labels to ensure safety and effectiveness?

The correct option is the Environmental Protection Agency (EPA). This agency is responsible for the regulation of pesticides and disinfectants to ensure they meet safety and efficacy standards before they can be marketed and used. The EPA evaluates the safety of these substances to protect human health and the environment, which is crucial in a food service setting where improper use of such chemicals can lead to contamination or health risks for consumers and staff.

Pesticide and disinfectant labels must display the EPA registration number, indicating that the product has been reviewed and approved by the agency for its intended use. This registration ensures that the product has been tested for effectiveness and poses minimal risks when used according to label directions.

Other options, while important in their respective areas, do not primarily oversee pesticide and disinfectant registrations. The Department of Agriculture typically oversees agricultural practices and may regulate some pesticide use in farming, but it is the EPA that handles the comprehensive registration process. The Food and Drug Administration mainly regulates food safety, drug efficacy, and some cosmetic items, while the Occupational Safety and Health Administration focuses on workplace safety rather than the regulation of pesticides.
