Adulterated Food and Drugs Under the FDCA: Enforcement and Liability

Under the Federal Food, Drug, and Cosmetic Act (FDCA), food and drugs are “adulterated” when their composition, purity, or manufacturing conditions fall below federal safety standards, even if no one has actually been harmed. Consequences range from product seizure and court injunctions to criminal prosecution carrying fines up to $1,000,000 and 20 years in prison for the most serious drug violations.¹²³

What “Adulterated” Actually Means

Adulteration describes a defect in the product itself or in the place it was made. It is separate from misbranding, which targets labeling and marketing claims. A single product can be both adulterated and misbranded, and each violation carries its own enforcement consequences.

The legal test does not require injury. A product is adulterated the moment it deviates from the applicable benchmark. A drug that contains 90% of its labeled strength is adulterated when it leaves the factory, whether or not any patient notices. That preventive posture is the whole point: regulators can pull product before anyone is hurt.

When Food Is Adulterated

Food falls into the adulterated category through several distinct routes. The broadest is any added poisonous or deleterious substance that could make the food unsafe, including chemical contaminants, unauthorized pesticide residues, and unsafe food additives.² Naturally occurring substances (small amounts of arsenic in rice, for example) get a narrow exception unless present in quantities that would ordinarily be harmful.

Food is automatically adulterated if it contains any filthy, putrid, or decomposed material, or if it came from a diseased animal or one that died from something other than slaughter.² Rodent droppings in a grain silo, insect fragments in processed flour, mold in canned goods — the contamination itself is the violation. No proof of illness needed.

Unapproved color additives create their own trigger. The FDA revoked authorization for FD&C Red No. 3 in January 2025. Food manufacturers have until January 15, 2027, to reformulate; drug manufacturers have until January 18, 2028.⁴ After those dates, any product still containing Red No. 3 will be treated as adulterated.⁵

Economic Adulteration

A separate set of provisions targets consumer deception even when nothing is unsafe. Food is adulterated if a valuable ingredient has been removed, if a cheaper substitute has been swapped in, if damage or poor quality has been concealed, or if a substance has been added to inflate bulk or weight.² Diluting olive oil with cheaper vegetable oil, injecting water into meat to inflate weight, or passing a juice blend off as 100% apple juice all sit here.

Dietary Supplements

Dietary supplements have their own standard under Section 402(f). A supplement is adulterated if it presents a “significant or unreasonable risk of illness or injury” when used as the label directs, or under ordinary conditions if there are no directions.² The government carries the burden of proof on every element, which means the FDA has to build its case before pulling a supplement rather than requiring the manufacturer to demonstrate safety upfront.

When Drugs and Devices Are Adulterated

Drugs face a more prescriptive standard. The United States Pharmacopeia (USP) and the National Formulary are the official benchmarks for strength, quality, and purity.⁶ If a drug carries a name recognized in those texts and its strength differs from, or its purity falls below, the published standard, it is legally adulterated.³ A tablet labeled at 500 mg that actually delivers 450 mg fails the test regardless of whether it still works clinically.

For drugs not listed in an official compendium, the standard shifts to whatever the manufacturer claims. If a company represents its product as having a particular strength or purity, the product must match.³ Unauthorized fillers or cheaper inactive substitutes trigger adulteration even when they do not affect how the drug works.

Medical devices face the parallel version of these rules. A device is adulterated if it fails an applicable performance standard or if its manufacturing methods, facilities, or controls do not conform to current good manufacturing practice.

Manufacturing Conditions Alone Can Trigger Adulteration

One of the more aggressive features of the FDCA is that a product can be deemed adulterated based purely on where and how it was made, even if no contaminant is ever found in the finished product. For food, if a facility operates under conditions where the product “may have become contaminated with filth” or “may have been rendered injurious to health,” every item produced there is legally adulterated.² The identical standard applies to drugs: preparation, packing, or holding under insanitary conditions that create a risk of contamination or health injury is enough.³

An FDA investigator who finds peeling paint above a production line, rodent activity in a warehouse, or improperly sanitized equipment can declare the output adulterated without testing a single unit. Regulators only have to show the conditions made contamination possible.

CGMP for Drugs

Pharmaceutical manufacturers must follow Current Good Manufacturing Practice regulations, which spell out facility design, equipment maintenance, quality control, and record-keeping. Every drug manufacturing facility must have a quality control unit with authority to approve or reject components, in-process materials, and finished products. Buildings must be free of rodents, birds, insects, and other pests. Equipment must be cleaned at intervals sufficient to prevent contamination. Production records must be retained for at least one year after the batch’s expiration date.⁷ Miss any of these and the drug is adulterated, even if the finished product tests fine.

FSMA Food Safety Plans

For food, the Food Safety Modernization Act (FSMA) requires most facilities to develop and implement a written food safety plan. The plan must be prepared or overseen by a “preventive controls qualified individual” and must include a hazard analysis, written preventive controls, a supply-chain program, a recall plan, monitoring procedures, corrective action procedures, and verification procedures.⁸ The plan must be signed, dated, and kept on site. Operating without one, or operating with one that does not match what is actually happening on the production floor, is the fastest route to an adulteration finding during inspection.

How the FDA Enforces Adulteration Violations

The FDCA gives the government three main tools: seizure, injunctions, and criminal prosecution. Enforcement usually escalates through a Warning Letter first.

Warning Letters

The FDA often opens with a Warning Letter identifying specific violations and requesting a response. Warning Letters are not legally binding on their own, but ignoring one is a serious mistake. The agency has stated that enforcement action may follow without further notice if violations continue.⁹ In practice, a Warning Letter is often the first documented step in a trail that ends in an injunction or consent decree.

Seizure

Any adulterated food, drug, or device in interstate commerce, or held for sale after shipment in interstate commerce, is subject to seizure through a federal court proceeding. If the court finds the product adulterated, it can order destruction or release under conditions like reconditioning or relabeling. FDA investigators can also administratively detain suspect products for up to 20 days, extendable to 30, while preparing a formal seizure action.¹⁰

Injunctions and Consent Decrees

Federal district courts can issue injunctions ordering a person or company to stop violating the FDCA.¹¹ Many injunction cases end in consent decrees, negotiated court orders where the company agrees to specific corrective steps. These are among the most punishing outcomes a manufacturer can face. A typical consent decree requires the company to stop manufacturing until an independent expert verifies full compliance, hire a third-party auditor for periodic assessments, and pay liquidated damages that can reach $20,000 per day for ongoing violations. The decree usually stays in effect for at least five years of continuous compliance before the company can petition for relief.

Criminal Penalties

Criminal penalties follow a tiered structure:

First offense (misdemeanor): up to one year in prison and a fine of up to $1,000.¹
Repeat offense or intent to defraud: up to three years in prison and a fine of up to $10,000.¹
Knowingly adulterating a drug with serious health risk: up to 20 years in prison and a fine of up to $1,000,000.¹
Counterfeit drugs or devices: up to 10 years in prison.¹

Separate civil penalties apply to specific food adulteration violations. A person who introduces food adulterated with an unsafe non-pesticide contaminant into interstate commerce faces civil penalties of up to $50,000 per violation for an individual and $250,000 for a company, capped at $500,000 for all violations in a single proceeding.¹

Debarment

For the pharmaceutical industry, debarment can end a career or a company. Any individual convicted of a federal felony related to drug development, approval, or regulation must be debarred from providing services to any company with an approved or pending drug application. Companies convicted of felonies related to the drug approval process face mandatory debarment from submitting abbreviated drug applications. The FDA also has discretionary authority to debar individuals or firms convicted of related misdemeanors or state felonies when the conduct undermines drug regulatory integrity.¹²

Personal Liability for Corporate Officers

The FDCA is one of the few federal statutes where a corporate executive can be criminally liable without any proof of personal wrongdoing or even knowledge of the violation. Under the Park doctrine, named after the 1975 Supreme Court decision in United States v. Park, a person in a position of authority within a company can be convicted of a misdemeanor FDCA violation simply because they had the power to prevent it and failed to do so.¹

A CEO does not have to personally contaminate a product or even know about the contamination. If the violation happened under their authority and they had the organizational power to prevent it, that is enough. First-offense Park doctrine prosecutions typically end in misdemeanor convictions and modest fines, but they carry collateral consequences: a conviction can trigger mandatory debarment from the pharmaceutical industry, disqualify an individual from participating in federal healthcare programs, and permanently damage professional reputation. Consent decrees routinely name individual officers as defendants alongside their companies.

Imported Food and Drugs

Foreign-manufactured food and drugs face additional scrutiny at the border. Under Section 801, the FDA can refuse admission to any product that “appears” to violate federal law, a lower threshold than what applies to domestic enforcement. For products with a documented history of violations, the FDA issues Import Alerts authorizing automatic detention without physical examination. Once a foreign manufacturer or product lands on an Import Alert, every future shipment is detained unless the importer can affirmatively show the specific violation is not present in that shipment.¹³

An importer has ten business days to respond to a detention notice and contest the finding. Missing that deadline without an extension leads to a refusal of admission that is treated as final. Refused products must be destroyed or exported under Customs and Border Protection supervision within 90 days of the refusal notice, and the FDA has no authority to extend that window.¹⁴ Food importers also carry ongoing verification duties under the Foreign Supplier Verification Program, requiring risk-based checks that imported food meets U.S. safety standards.¹⁵

Reporting Obligations and Recalls

Discovering an adulterated product triggers immediate reporting duties. For food, the Reportable Food Registry requires a responsible party to submit a report no later than 24 hours after determining that a food is reportable, meaning it presents a reasonable probability of serious health consequences.¹⁶ For biological products such as vaccines and blood products, manufacturers must report deviations from manufacturing standards that could affect safety, purity, or potency within 45 calendar days.¹⁷

Recall authority splits along product lines in ways that surprise people. For food, FSMA gave the FDA mandatory recall authority, but only where there is a reasonable probability that the product is adulterated and will cause serious health consequences or death. Even then, the agency must first give the company a chance to recall voluntarily. Only the FDA Commissioner can order a mandatory food recall, and the company can request an informal hearing within two days of the order.¹⁸ For drugs, the FDA still largely lacks direct mandatory recall authority. The agency typically requests voluntary recalls, and if a manufacturer refuses, the FDA pursues an injunction or seizure action through the courts to halt distribution.

Consumers Cannot Sue Under the FDCA

Individual consumers cannot sue manufacturers directly under the FDCA for selling adulterated products. All enforcement actions under the statute must be brought by the federal government. Someone harmed by contaminated food or a defective drug has to look to state consumer protection laws, state product liability claims, or state tort law for compensation. A successful FDA enforcement action may result in a product recall or a manufacturer paying federal fines, but it will not put money in the pocket of an injured consumer. A separate state-court lawsuit is what does that.
