Food and Drug Administration (FDA): What It Is and Does


The Food and Drug Administration (FDA) plays a crucial role in ensuring the safety and efficacy of a wide range of products that affect public health. From food and drugs to medical devices and cosmetics, the FDA’s regulatory oversight impacts the lives of millions. Understanding what the FDA is and what it does can provide valuable insights into its importance and influence on daily life.

What is the FDA?

The FDA is a federal agency within the United States Department of Health and Human Services (HHS). It was established in 1906 with the passage of the Pure Food and Drug Act, which aimed to combat the sale of adulterated and misbranded food and drug products. Today, the FDA’s mission has expanded to encompass a wide range of products, ensuring they are safe, effective, and properly labeled.

Key Responsibilities of the FDA

1. Regulating Food Safety

The FDA oversees the safety of approximately 80% of the U.S. food supply, including everything except meat, poultry, and some egg products, which are regulated by the USDA. The FDA sets standards for food safety, inspects food production facilities, and enforces regulations to prevent foodborne illnesses. They also oversee the safety of food additives and dietary supplements.

2. Approving and Monitoring Pharmaceuticals

One of the FDA’s most well-known roles is the approval of new drugs. Before a pharmaceutical product can be marketed, it must undergo rigorous testing in clinical trials to demonstrate its safety and efficacy. The FDA reviews these trial results and, if the drug meets their standards, grants approval for its use. The agency also monitors drugs post-approval to ensure ongoing safety and to identify any long-term side effects.

3. Regulating Medical Devices

The FDA classifies medical devices into three categories based on their risk level: Class I (low risk), Class II (moderate risk), and Class III (high risk). Each class requires different levels of regulatory control. The FDA reviews and approves devices before they can be marketed, ensuring they meet safety and effectiveness standards. The agency also monitors devices after they are on the market to identify any potential issues.

4. Overseeing Vaccines, Blood, and Biologics

The FDA regulates vaccines, blood products, and other biologics to ensure they are safe, effective, and available to the public. This includes reviewing and approving new vaccines, overseeing the collection and processing of blood products, and ensuring the safety of biological therapies.

5. Ensuring Cosmetic Safety

While cosmetics do not require FDA approval before being marketed, the agency has the authority to regulate their safety. This includes ensuring that cosmetics are properly labeled, free of harmful ingredients, and that any claims made about them are truthful.

6. Regulating Tobacco Products

The FDA also regulates the manufacturing, distribution, and marketing of tobacco products. This includes setting standards for tobacco product ingredients, reviewing new tobacco products before they can be marketed, and enforcing restrictions on advertising and sales to minors.

How the FDA Protects Public Health

The FDA employs a variety of methods to protect public health, including:

Inspections and Compliance:

The FDA conducts inspections of manufacturing facilities to ensure compliance with regulations. This includes both domestic and international facilities.

Enforcement Actions:

When companies violate FDA regulations, the agency can take enforcement actions such as warning letters, fines, product recalls, and even criminal prosecutions.

Public Awareness Campaigns:

The FDA runs public education campaigns to inform consumers about product safety, healthy living, and disease prevention.

Scientific Research:

The FDA conducts and supports research to improve regulatory science and develop new methods for assessing product safety and efficacy.


The Food and Drug Administration (FDA) is a vital agency that plays a critical role in safeguarding public health. Its comprehensive regulatory oversight ensures that the food we eat, the drugs we take, and the medical devices we use are safe and effective.

Understanding the FDA’s functions helps highlight the importance of its work and the impact it has on everyday life. From approving life-saving medications to ensuring the safety of our food supply, the FDA’s mission is essential to maintaining and promoting public health.
