Introduction to the FDA
Mandate for Public Health
The United States Food and Drug Administration (FDA) operates as a federal agency under the Department of Health and Human Services. Its fundamental mission is to protect and advance public health by meticulously controlling and supervising a vast array of products. This oversight spans critical areas such as food safety, tobacco products, dietary supplements, prescription and over-the-counter medications, vaccines, biopharmaceuticals, blood transfusions, medical devices, electromagnetic radiation-emitting devices (ERED), cosmetics, animal foods and feed, and various veterinary products.
Legal Framework
At its core, the FDA enforces the Federal Food, Drug, and Cosmetic Act (FD&C). Beyond this foundational legislation, the agency also upholds other significant laws, notably Section 361 of the Public Health Service Act, along with its associated regulations. This broad legal authority extends beyond conventional food and drug categories, encompassing diverse areas like the regulation of lasers, cellular phones, and condoms. Furthermore, the FDA plays a crucial role in disease control, ranging from household pets to human sperm donations utilized in assisted reproduction.
Leadership and Governance
The FDA is steered by the Commissioner of Food and Drugs, a presidential appointee confirmed by the Senate. This Commissioner reports directly to the Secretary of Health and Human Services. As of the provided information, Marty Makary serves as the current Commissioner, with Sara Brenner as the Principal Deputy Commissioner, guiding the agency's extensive operations and policy implementations.
Organizational Structure

Geographic Footprint
Headquarters Evolution
The FDA's primary headquarters are situated within the White Oak Federal Research Center in Silver Spring, Maryland. Since 1990, the agency has maintained a presence on this 130-acre campus. A significant consolidation effort, initiated by the General Services Administration (GSA) in 2001, aimed to centralize the FDA's 25 operations across the Washington metropolitan area, including its former Rockville headquarters and various fragmented office buildings. By December 2018, the White Oak campus housed 10,987 employees across approximately 3.8 million square feet of space, encompassing ten offices and four laboratory buildings.
Future Expansion
With the enactment of the FDA Reauthorization Act of 2017, the agency anticipates a substantial 64% increase in its workforce, projecting 18,000 employees over the next 15 years. To accommodate this growth, plans are underway to add approximately 1.6 million square feet of office and specialized space to the existing facilities. The National Capital Planning Commission approved a new master plan for this expansion in December 2018, with construction projected for completion by 2035, contingent upon GSA appropriations.
Field and Global Reach
Beyond its headquarters, the FDA maintains a broad network of 223 field offices and 13 laboratories across all 50 U.S. states, the U.S. Virgin Islands, and Puerto Rico. This extensive domestic presence is complemented by international offices established in 2008 in key regions including China, India, Costa Rica, Chile, Belgium, and the United Kingdom, underscoring the agency's global commitment to product safety and public health.
Scope and Funding
Vast Oversight
As of 2021, the FDA's regulatory responsibilities extended to an immense portfolio of products, valued at an estimated $2.7 trillion. This encompasses a wide range of food, medical, and tobacco products, highlighting the agency's critical and far-reaching influence on the American economy and public welfare.
Funding Model
The FDA's annual budget, which stood at US$6.5 billion in 2022, is funded through a hybrid model. Approximately 54% of its budget is derived from federal government appropriations. The remaining 46% is covered by industry user fees. These fees are paid by regulated industries for specific FDA services, such as expediting drug reviews, a practice that has also raised discussions regarding potential industry influence.
Pharmaceutical Contributions
Notably, pharmaceutical firms contribute a significant portion—around 75%—of the FDA's budget specifically allocated for drug review processes. This funding mechanism, while designed to accelerate reviews, is a point of ongoing discussion regarding its implications for regulatory independence and the thoroughness of drug evaluations.
Regulatory Programs
Emergency Approvals (EUA)
The Emergency Use Authorization (EUA) mechanism is a vital tool enabling the rapid availability and deployment of medical countermeasures during public health crises. This includes essential items like vaccines and personal protective equipment, as demonstrated during the Zika and Ebola virus epidemics, and most recently, the COVID-19 pandemic. EUAs facilitate quicker access to critical tools when traditional approval pathways are too slow for urgent needs.
Food & Supplements
The FDA's regulation of food and dietary supplements is governed by various statutes, primarily the Federal Food, Drug, and Cosmetic Act. The agency oversees the quality of food substances and monitors labeling claims regarding composition and health benefits. Categories include foods, food additives, added substances, and dietary supplements (vitamins, minerals, herbs, amino acids, enzymes). Under the Dietary Supplement Health and Education Act of 1994 (DSHEA), manufacturers are responsible for product safety and labeling, with the FDA maintaining an "Ingredient Advisory List" for substances requiring further evaluation. It's important to note that the FDA does not "approve" applied coatings in food processing; rather, these materials are deemed "FDA Compliant" or "FDA Acceptable" based on adherence to regulations.
Medications
The Center for Drug Evaluation and Research (CDER) employs distinct requirements for new, generic, and over-the-counter (OTC) drugs. New molecular entities undergo rigorous scrutiny via a New Drug Application (NDA) process, which includes extensive testing and clinical trials. Critics occasionally argue that these standards are not always sufficient. Generic drugs, chemical and therapeutic equivalents of name-brand drugs, are approved through an Abbreviated New Drug Application (ANDA) or the 505(b)(2) pathway, requiring evidence of interchangeability or therapeutic equivalence. OTC drugs, like aspirin, are regulated based on a list of approximately 800 approved ingredients. The FDA's Office of Prescription Drug Promotion (OPDP) regulates prescription drug advertising, ensuring "fair balance" between benefits and risks, while the Federal Trade Commission (FTC) oversees OTC drug advertising. Post-market safety surveillance involves mandatory adverse drug experience reporting and, for some drugs, Risk Evaluation and Mitigation Strategies (REMS) to ensure safe use.
Biologics & Devices
The Center for Biologics Evaluation and Research (CBER) ensures the safety and efficacy of biological therapeutic agents, including blood products, vaccines, and gene therapies. New biologics undergo a Biologics License Application (BLA) process, similar to drug approvals. This regulatory authority originated from the 1902 Biologics Control Act and the 1944 Public Health Service Act, with oversight transferred to the FDA in 1972.
The Center for Devices and Radiological Health (CDRH) is responsible for premarket approval, manufacturing oversight, and safety of medical devices, from toothbrushes to neurostimulators. CDRH also regulates non-medical radiation-emitting devices like cell phones and microwave ovens, requiring technical reports, enforcing safety standards, and ordering recalls of defective products. A key distinction is "FDA-Cleared" (substantially equivalent to existing devices) versus "FDA-Approved" (new devices demonstrating safety and efficacy).
Cosmetics & Veterinary
Cosmetics are regulated by the Center for Food Safety and Applied Nutrition (CFSAN). Generally, cosmetics do not require premarket approval unless they make "structure or function claims" that classify them as drugs. However, all color additives must be FDA-approved. Cosmetics labeling is regulated, and products not safety-tested must carry a warning. Historically, the industry was largely responsible for its own safety, but the 2023 Cosmetics Regulatory Modernization Act (MoCRA) introduced stricter regulations, including mandatory adverse event reporting, safety substantiation, and Good Manufacturing Practices (GMP), and granted the FDA mandatory recall authority.
The Center for Veterinary Medicine (CVM) regulates food additives and drugs for animals, including pet food and animal medical devices. CVM also enforces regulations to prevent the spread of bovine spongiform encephalopathy through feed inspections. Animal vaccines, however, are regulated by the U.S. Department of Agriculture.
Tobacco & Organisms
The FDA regulates tobacco products under the 2009 Family Smoking Prevention and Tobacco Control Act, which mandates color warnings on packaging and advertising. Implementation of graphic warning labels faced legal challenges, with tobacco companies arguing infringement on commercial free speech. In 2017, the FDA proposed reducing nicotine levels in cigarettes to approximately 0.7 milligrams per gram of tobacco.
The FDA also regulates living organisms as medical devices. In 2004, medical maggots became the first living organism cleared for production and marketing as a prescription medical device, followed by medicinal leeches in June 2004. Additionally, the FDA mandates pasteurization of milk to eliminate bacteria, ensuring food safety.
International Cooperation
The FDA engages in international cooperation to enhance regulatory transparency and coordination. A notable example is the Canada-United States Regulatory Cooperation Council (RCC), established in 2011, which aimed to align regulations, such as those for common cold antihistamine ingredients. More recently, in 2018, the FDA collaborated with global law enforcement agencies through Interpol as part of Operation Pangea XI. This operation targeted websites illegally selling unapproved and potentially dangerous prescription drugs, including opioids, oncology, and antiviral medications, to U.S. consumers, focusing on uncovering complex online drug networks involved in transaction laundering schemes.
Historical Evolution
Early Beginnings
Prior to the 20th century, federal regulation of food and pharmaceuticals was minimal, with exceptions like the Vaccine Act of 1813. The FDA's origins trace back to the late 19th century within the U.S. Department of Agriculture's Division of Chemistry. Under Chief Chemist Harvey Washington Wiley, appointed in 1883, the Division began investigating food and drug adulteration and misbranding. Wiley's advocacy, fueled by muckraking journalists like Upton Sinclair and the broader Progressive Era movement, pushed for increased federal oversight.
Foundational Acts
A critical turning point was the 1902 Biologics Control Act, enacted after a diphtheria antitoxin contaminated with tetanus caused the deaths of thirteen children. This event underscored the need for stringent biological product regulation. In June 1906, President Theodore Roosevelt signed the Pure Food and Drug Act (the "Wiley Act"), prohibiting interstate transport of "adulterated" or "misbranded" food and drugs. This Act empowered Wiley's Bureau of Chemistry, though its authority was initially limited by judicial interpretations. In 1927, the regulatory powers were reorganized under the Food, Drug, and Insecticide Administration, which was shortened to the Food and Drug Administration (FDA) three years later.
Catalytic Tragedies
Public outcry over injurious products, including radioactive beverages and ineffective "cures," spurred calls for stronger laws in the 1930s. The 1937 Elixir Sulfanilamide tragedy, where over 100 people died from a toxic, untested drug solvent, accelerated legislative action. President Franklin Delano Roosevelt signed the Federal Food, Drug, and Cosmetic Act (FD&C Act) into law on June 24, 1938. This landmark legislation mandated pre-market safety review for all new drugs, banned false therapeutic claims without requiring proof of fraudulent intent, and authorized the FDA to set food standards to combat fraud.
Modern Drug Regulation
The 1951 Durham-Humphrey Amendment codified "prescription-only" drugs, granting the FDA extensive powers for post-marketing recalls. The thalidomide tragedy, which caused severe birth defects globally but largely spared American mothers due to FDA official Frances Oldham Kelsey's refusal to authorize the drug, led to the 1962 Kefauver-Harris Amendment. This amendment revolutionized FDA authority by requiring "substantial evidence" of a drug's efficacy in addition to safety, marking the beginning of the modern FDA approval process. These reforms increased the time and difficulty of bringing drugs to market.
21st-Century Reforms
Critical Path Initiative
Launched in March 2004 with the report "Innovation/Stagnation: Challenge and Opportunity on the Critical Path to New Medical Products," the Critical Path Initiative represents the FDA's strategic effort to modernize the scientific processes involved in developing, evaluating, and manufacturing FDA-regulated products. This initiative aims to proactively address scientific and technical challenges, ensuring that regulatory science keeps pace with innovation.
Patient Access & Safety
The Compassionate Investigational New Drug program, established after the 1978 Randall v. U.S. ruling, allowed access to medical marijuana for specific patients. However, the 2006 case Abigail Alliance v. von Eschenbach, which sought to mandate access to unapproved drugs for terminally ill patients after Phase I testing, was ultimately denied by the Supreme Court, affirming the FDA's authority over unapproved medications. The Vioxx recall in 2004, linked to thousands of heart attacks, spurred significant reforms in post-marketing drug safety. A 2006 Institute of Medicine report highlighted deficiencies and called for increased FDA regulatory powers, funding, and independence. Many recommendations were integrated into the Food and Drug Administration Amendments Act of 2007, leading to programs like Risk Minimization Action Plans (RiskMAPS) to ensure drug benefits outweigh risks post-market.
Pediatric Drug Testing
Historically, only 20% of drugs prescribed for children in the United States were tested in pediatric populations, leading to "off-label" use. This was due to small market size, cost-effectiveness concerns, and ethical hurdles regarding informed consent. Initial FDA rules in 1994 requiring disclaimers for untested drugs proved insufficient. A 1997 proposal for mandatory pediatric trials was preempted by federal court. Congress intervened with the Food and Drug Administration Modernization Act of 1997, offering six-month patent extensions for drugs with pediatric trial data. The Best Pharmaceuticals for Children Act of 2007 reauthorized these incentives and allowed NIH-sponsored testing. The Pediatric Research Equity Act of 2003 further codified the FDA's authority to mandate manufacturer-sponsored pediatric trials as a last resort.
Innovation & Efficiency
The Priority Review Voucher (PRV) program, introduced by the Food and Drug Administration Amendments Act of 2007, awards transferable vouchers for developing treatments for neglected tropical diseases, incentivizing pharmaceutical innovation. The Food and Drug Administration Safety and Innovation Act of 2012 extended this authorization. For biotechnology drugs, which are complex and expensive, the 1984 Hatch-Waxman Act did not include a generic approval process. Bills to create an Abbreviated New Drug Application (ANDA) process for generic biologics were introduced but not passed. In 2013, the FDA issued guidance for mobile medical applications, regulating them based on marketing claims to protect users. To streamline regulatory data flow, the Electronic Submissions Gateway (ESG) was introduced in 2006, allowing organizations to submit data electronically via WebTrader or AS2 protocols.
Criticism & Challenges
Scrutiny and Deficiencies
Given its extensive regulatory oversight over products vital to American health, the FDA's powers and decisions are under constant scrutiny from both governmental and non-governmental organizations. A significant 2006 Institute of Medicine report on pharmaceutical regulation identified major deficiencies in the FDA's system for ensuring drug safety. The report advocated for increased regulatory powers, funding, and greater independence for the agency to effectively fulfill its mandate.
Food Division Concerns
A 2022 article from Politico highlighted concerns regarding the FDA's food division, suggesting that food safety may not be a high priority within the agency. The report pointed to structural and leadership issues within the food division and noted a tendency to defer to industry interests. This perceived deference is sometimes attributed to the significant lobbying and influence exerted by large food companies in Washington, D.C., raising questions about the impartiality and effectiveness of food regulation.
Staffing and Policy Shifts
Recent events have also brought the FDA under criticism regarding staffing and policy. In February 2025, the head of the FDA's food division resigned in protest over "indiscriminate" layoffs of 89 staff members by the Donald Trump administration, signaling potential impacts on the agency's operational capacity. Furthermore, in May 2025, the FDA announced policy changes for COVID-19 vaccines, intending to limit approved indications for adults over 65 and high-risk individuals in the fall. For healthy Americans under 65, the agency indicated a likely requirement for additional placebo-controlled clinical trials to demonstrate benefit before approving wider access, a move that could be seen as a shift in public health strategy.
