Food allergen law in the United States has evolved significantly over the past two decades, driven by the growing recognition that undeclared allergens in food are a genuine public health concern. According to the Network for Public Health Law, anaphylactic reactions to food result in approximately 30,000 emergency room visits, 2,000 hospitalizations, and 150 deaths in the United States every year. Food allergen law exists to reduce these numbers by creating enforceable obligations for food manufacturers and processors and increasingly for restaurants and food service operations to identify, disclose, and control allergens in the food they produce and serve.
Proper understanding of food allergens is essential while operating in the food business, especially if you are preparing or serving food. AAA Food Handler offers accredited allergen awareness training that helps food service professionals understand and comply with food allergen law across all 50 states.
What Is Food Allergen Law?
Food allergen law refers to the body of federal and state statutes, regulations, and enforcement frameworks that govern how food businesses must identify, label, disclose, and control major food allergens in the food they produce, package, and serve. In the United States, food allergen law operates at two distinct levels: federal law governing packaged food labeling and manufacturing, and state law governing restaurant and food service operations.
At the federal level, the two foundational statutes are the Food Allergen Labeling and Consumer Protection Act of 2004 and the Food Allergy Safety, Treatment, Education, and Research Act of 2021, both of which are enforced by the FDA. At the state level, laws vary significantly, with some states requiring allergen training, menu disclosure, or specific operational controls that go beyond federal requirements.
What Is the Food Allergen Labeling and Consumer Protection Act?
The Food Allergen Labeling and Consumer Protection Act, known as FALCPA, was signed into law in 2004 and represents the foundational federal statute governing allergen labeling in the United States. FALCPA amended the Federal Food, Drug, and Cosmetic Act to define the term “major food allergen” and require that all packaged foods regulated by the FDA clearly identify any major food allergen in the product either by name in the ingredient list or through a plain-language “Contains” statement immediately following the ingredient list.
When FALCPA was enacted, it identified eight foods as major food allergens: milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, and soybeans. At the time of its passage, these eight allergens were responsible for approximately 90 percent of serious food allergic reactions in the United States.
FALCPA applies to all packaged foods regulated by the FDA, including dietary supplements and bulk containers intended for further processing. It does not apply to food prepared and served in restaurants, food trucks, or other retail food service establishments, which remain regulated under a separate framework.
What Is the FASTER Act and What Did It Change?
The Food Allergy Safety, Treatment, Education, and Research Act, known as the FASTER Act, was signed into law on April 23, 2021, and represents the first update to the list of major food allergens since FALCPA law was passed in 2004. The FASTER Act added sesame as the ninth major food allergen recognized under federal law, effective January 1, 2023.
From January 1, 2023, onwards, all FDA requirements applicable to major food allergens, including labeling disclosure, current Good Manufacturing Practices, and preventive controls under FSMA, apply to sesame in the same way they apply to the original eight allergens. Food manufacturers must declare sesame by name whenever it is used as an ingredient, either in the ingredient list or in a “Contains sesame” statement.
It is estimated that more than 1.5 million people in the United States are allergic to sesame, and the prevalence of sesame allergy has increased significantly worldwide over the past two decades. The FASTER Act also requires ongoing federal reporting on food allergy surveillance, diagnostic development, and treatment research.
For a detailed breakdown of all nine major allergens and how they appear in food service settings, the major food allergens page covers each allergen’s common sources and cross-contact risks in detail.
What Is the Difference Between Food Allergen Law for Packaged Foods and for Restaurants?
The most significant gap in U.S. food allergen law is the distinction between obligations for packaged food manufacturers and obligations for restaurants. This gap is now beginning to narrow through state legislation but remains substantial at the federal level.
FALCPA and the FASTER Act apply exclusively to packaged foods regulated by the FDA. A manufacturer that produces a product containing peanuts must declare peanuts on the label. A restaurant that prepares a dish containing peanuts has no equivalent federal obligation to disclose that allergen on its menu.
For packaged food manufacturers, federal law creates a strict, enforceable labeling obligation with recall authority behind it. For restaurants, federal law creates a more general duty of care through the FDA Food Code’s active managerial control requirements and, for hybrid manufacturing operations, FSMA’s preventive controls.
Beyond these frameworks, restaurant allergen disclosure obligations in the United States have historically depended on state law, which varies widely from no requirement at all to mandatory training, signage, and menu disclosure. California’s ADDE Act, effective July 1, 2026, represents the first state law to require full menu allergen disclosure for large restaurant chains.
What Does Food Allergen Law Require on Packaged Food Labels?
Federal food allergen law requires that the label of any packaged food regulated by the FDA clearly identify each major food allergen present in the product. This requirement can be satisfied in two ways.
The first method is declaration within the ingredient list itself, using the common or usual name of the allergen source, such as “milk,” “peanuts,” or “sesame,” even when the ingredient has a different technical name. For example, “casein” must be followed by “milk” in parentheses because consumers may not recognize casein as a dairy derivative.
The second method is a “Contains” statement placed immediately after or adjacent to the ingredient list, such as “Contains: Milk, Peanuts, Sesame.” Both methods are legally acceptable, and manufacturers may use either or both.
For a detailed breakdown of packaged food allergen labeling requirements, the allergen labeling page covers disclosure rules and best practices for food manufacturers and distributors.
Does Federal Law Require Restaurants to Disclose Allergens on Menus?
No. As of June 2026, there is no federal law that requires restaurants to disclose major food allergens on their menus for food prepared and served onsite. FALCPA and the FASTER Act apply only to packaged foods, not to unpackaged food prepared and served in food service establishments.
However, federal law creates indirect allergen disclosure obligations for restaurants in two ways. The 2022 FDA Food Code, which most states have adopted as the basis for retail food safety regulation, requires food establishments to be able to communicate ingredient information, including allergen content to customers upon request and requires staff to acknowledge when they cannot confirm the absence of a specific allergen. FSMA’s preventive controls requirements also apply to facilities that both manufacture packaged food products and serve food, creating written allergen control plan obligations for those hybrid operations.
The practical result is that while federal law does not mandate restaurant menu allergen labeling, it does create a duty of care that exposes restaurants to civil liability when allergen information is communicated inaccurately or negligently.
What Is the California ADDE Act and What Does It Require?
The Allergen Disclosure for Dining Experiences Act, known as the ADDE Act, was enacted through California Senate Bill 68, signed by Governor Gavin Newsom on October 13, 2025. It makes California the first state in the United States to require restaurant menu allergen disclosure, with an effective date of July 1, 2026.
The ADDE Act applies to restaurant chains with 20 or more locations nationwide, operating under the same name and offering substantially the same menu items. Food trucks, carts, and non-permanent food facilities are exempt.
Covered restaurants must provide written notification of all nine major food allergens that they know or reasonably should know are present as ingredients in each menu item. This disclosure can be provided directly on a physical menu, on a digital menu via QR code, or through an allergen chart, provided a print alternative is always available. Enforcement is handled by the California Department of Public Health and local health agencies. Penalties are limited to fines available under existing health code violation frameworks, and “may contain” or shared facility disclosures are not required.
Are There Other State Allergen Disclosure Laws for Restaurants?
Yes. While California’s ADDE Act is the most comprehensive restaurant allergen disclosure law in the United States, at least nine other states have enacted allergen-related requirements for food service establishments.
Massachusetts requires restaurants to post customer notification and train designated staff as Allergen Awareness certified. New York requires conspicuous menu notices advising guests to notify their server of food allergies, with civil penalties up to $125 per violation. Connecticut, under Public Act 23-115, effective January 1, 2025, requires food establishments to post customer notification and train staff on allergen response procedures. Michigan’s HB-5402 requires restaurants serving unpackaged food to post allergy advisories on menus or at points of order. Illinois requires allergen awareness training, including gluten and celiac disease education for Certified Food Service Sanitation Managers under Public Act 104-0090, effective January 1, 2026. For the full breakdown of Illinois requirements, the Illinois allergen awareness page covers documentation and training obligations in detail.
The Asthma and Allergy Foundation of America has confirmed active legislative efforts in multiple additional states for 2026 and beyond due to the impact of California’s ADDE Act.
What Does "May Contain" Mean Legally and Is It Required?
“May contain” statements, also known as precautionary allergen labeling or PAL, are voluntary warnings that food manufacturers use to indicate that a product may have been exposed to an allergen through shared equipment, production lines, or facilities, even when the allergen is not an intentional ingredient.
Under federal law, “may contain” statements are not required by FALCPA or the FASTER Act. Manufacturers use them voluntarily as a liability management tool and as a courtesy to consumers with food allergies. Because these statements are unregulated and unstandardized, they vary widely in their language and in the threshold levels of allergen contamination they are intended to convey, which can make them confusing or unreliable for consumers with severe allergies.
The FDA has historically considered requiring standardized precautionary allergen labeling but has not finalized any such rule as of June 2026. The California ADDE Act specifically states that covered restaurants are not required to provide “may contain” or “shared facility” information, reflecting the current legal consensus that precautionary disclosure remains voluntary rather than mandatory.
What Does the FDA Food Code Require for Allergen Management in Restaurants?
The 2022 FDA Food Code strengthened allergen management requirements for retail food establishments in two significant ways. First, it requires that food employees be knowledgeable about the major food allergens present in the menu items they prepare and serve and that the Person in Charge be able to demonstrate this knowledge during a health inspection. Second, it requires that food establishments be able to communicate accurate allergen information to consumers upon request and that staff acknowledge clearly when they cannot confirm the absence of a specific allergen in a dish.
Beyond these disclosure and knowledge requirements, the FDA Food Code requires establishments to control allergen cross-contact during food preparation. This includes using separate equipment and utensils for allergen-free preparations, cleaning and sanitizing surfaces between allergen-containing and allergen-free orders, and ensuring that allergen-free dishes are not contaminated during plating, garnishing, or service.
The 2022 edition also added sesame to the allergen awareness and cross-contact prevention requirements following the FASTER Act’s effective date, requiring food establishments to treat sesame with the same operational controls as the original eight allergens.
What Is Allergen Cross-Contact and What Does the Law Say About It?
Allergen cross-contact occurs when a food allergen is unintentionally transferred from one food to another through shared equipment, utensils, surfaces, or hands, even when the allergen is not a listed ingredient in the receiving food. Cross-contact differs from cross-contamination in that the allergen proteins are not destroyed by cooking and can trigger a reaction even at trace levels.
The FDA Food Code treats allergen cross-contact prevention as a required operational control, not a voluntary best practice. Under FSMA’s Preventive Controls for Human Food rule, food manufacturers must include allergen preventive controls in their written food safety plans, including procedures to prevent cross-contact during storage, handling, and production. For retail food establishments, the FDA Food Code embeds allergen cross-contact prevention within its active managerial control expectations, making it a priority violation during health inspections if cross-contact controls are demonstrably absent.
From a legal liability perspective, allergen cross-contact is one of the most common causes of food allergy incidents in restaurants. Civil courts have consistently held that restaurants, which assure a guest that a dish is allergen-free and then serve food contaminated through cross-contact can be held liable under negligence, strict liability, or breach of warranty theories.
Does Food Allergen Law Require Staff Training in Restaurants?
At the federal level, the FDA Food Code requires that all food employees have knowledge appropriate to their duties, which includes knowledge of the major food allergens and how to prevent cross-contact. This creates a training obligation for food establishments without mandating a specific training format or certification.
At the state level, training requirements vary significantly. Massachusetts, Connecticut, Michigan, and several other states require designated staff to complete formal allergen awareness training. Illinois requires Certified Food Service Sanitation Managers to complete allergen awareness training that explicitly includes gluten and celiac disease education. California’s ADDE Act, while focused on menu disclosure, also creates a practical training obligation for covered restaurants since accurate allergen disclosure requires staff who understand which ingredients contain which allergens.
AAA Food Handler’s allergen awareness training program meets the requirements of state health departments across all 50 states and covers the nine major allergens, cross-contact prevention, guest communication, and the operational controls that food allergen law requires in food service settings.
What Are the Legal Consequences of Violating Food Allergen Law?
At the state regulatory level, inspectors can cite restaurants for allergen-related Priority Foundation violations for inadequate allergen management procedures, staff knowledge gaps, or cross-contact The legal consequences of violating food allergen law fall into three categories: regulatory action, civil liability, and criminal liability in the most severe cases.
For packaged food manufacturers, FDA enforcement can result in mandatory recalls, warning letters, import alerts, and injunctions. Since the FASTER Act’s sesame requirement took effect in January 2023, 115 sesame-related recalls occurred between 2012 and September 2024, with 46 percent concentrated in 2023, reflecting the scale of compliance challenges that new allergen designations create.
For restaurants, the most significant risk is civil liability. When a restaurant assures a customer that a dish is allergen-free and that customer suffers an anaphylactic reaction, the restaurant can face personal injury or wrongful death claims under strict liability, negligence, or breach of warranty. A 2023 wrongful death case at Disney Springs in Florida, in which a guest died after being assured her meal was allergen-free, illustrates the severity of this exposure.
control failures.
Who Enforces Food Allergen Law in the United States?
Food allergen law enforcement in the United States is distributed across multiple agencies, depending on the type of food business and the specific law at issue.
The FDA enforces FALCPA and the FASTER Act for packaged food manufacturers and processors. It conducts facility inspections, reviews labeling compliance, and issues recalls and enforcement actions when undeclared allergens are identified. The FDA also enforces the allergen-related provisions of FSMA’s Preventive Controls rule for food manufacturers.
State health departments enforce state-adopted versions of the FDA Food Code for restaurants and retail food establishments. This includes inspection-based enforcement of allergen knowledge requirements, cross-contact control procedures, and, in states with specific allergen laws, training and disclosure obligations.
For the California ADDE Act, enforcement authority rests with the California Department of Public Health and local health agencies, who conduct visual verification of menu compliance during routine inspections.
Civil enforcement occurs through private litigation when a food allergy incident results in personal injury or death. Plaintiffs can bring claims against restaurants, food manufacturers, distributors, or retailers, depending on where the allergen failure occurred in the supply chain.
How Has Food Allergen Law Changed in Recent Years?
Food allergen law in the United States has changed more rapidly between 2021 and 2026 than in the preceding fifteen years, driven by growing food allergy prevalence, increased consumer advocacy, and landmark state legislation.
The FASTER Act in 2021, effective January 2023, was the first change to the federal list of major allergens since FALCPA in 2004. The 2022 FDA Food Code strengthened allergen management and disclosure requirements for retail food establishments. California’s ADDE Act in 2025, effective July 2026, created the first state-level mandate for restaurant menu allergen disclosure in the United States. Connecticut, Michigan, Illinois, and Maryland have all enacted or updated allergen-related requirements for restaurants since 2023. The AAFA has confirmed active legislative efforts in multiple additional states for 2026 and beyond.
The direction of travel is clear: food allergen law is moving from a packaged-food-only framework toward a more comprehensive system that creates disclosure and training obligations for restaurants and food service operations as well. Food service operators who build allergen management systems now are better positioned for the wave of state-level legislation expected in the coming years.
How Does AAA Food Handler Help Restaurants Comply With Food Allergen Law?
Complying with food allergen law requires more than awareness of which allergens exist. It requires staff who can identify allergens in ingredients and dishes, communicate accurately with guests who have food allergies, prevent cross-contact during preparation and service, and operate within the documentation and training framework that health inspectors and state laws increasingly require.
AAA Food Handler’s food allergen certificate program equips food service professionals with the knowledge to meet these obligations. The program covers the nine major allergens and their common hidden sources, cross-contact prevention procedures aligned with FDA Food Code requirements, guest communication protocols for allergen-related requests, and the state-specific training requirements that apply in jurisdictions including Massachusetts, Connecticut, Illinois, and others.
The program is ANAB-CFP accredited, fully online, and recognized by health departments across all 50 states. As state-level allergen disclosure and training laws continue to expand following California’s ADDE Act, having documented allergen training records for all staff will become an increasingly important component of food allergen law compliance.
