Which agency is responsible for regulating food and drug products in the United States?

The Food and Drug Administration (FDA) is the agency specifically tasked with ensuring the safety and efficacy of food and drug products in the United States. This includes overseeing the regulation of pharmaceuticals, food safety, dietary supplements, and cosmetic products. The FDA's primary role is to protect public health by ensuring that products meet certain standards before they can be marketed and sold.

The agency conducts rigorous scientific evaluations of new drugs and food products, establishes guidelines for labeling and advertising, and monitors food supply safety. This regulatory oversight is vital in preventing harmful products from reaching consumers and in ensuring that medications are both safe and effective for public use.

While the USDA focuses on agriculture, meat, poultry, and egg products, and the CDC is primarily concerned with public health and safety through disease prevention, the FDA's regulatory authority directly pertains to food and drug products specifically, making it the correct answer to this question. The USDHHS oversees various health-related initiatives, but like the USDA and CDC, it does not have the specific focus on the regulation of food and drugs that the FDA does.
