FDA Nine Major Food Allergens Guide for Restaurants

Managing Allergen Safety in Commercial Kitchens

Food allergies are a major public health concern in the United States, affecting millions of people. For restaurant operators, food safety is a critical operational and legal responsibility. Managing food allergens is not just about avoiding customer complaints; it is about saving lives and maintaining compliance with state and local health regulations.

When a person with a severe food allergy ingests even a microscopic trace of an allergen, it can trigger anaphylaxis—a life-threatening allergic reaction that can restrict breathing, cause rapid blood pressure drops, and lead to death. Because there is no cure for food allergies, the only defense for allergic consumers is absolute avoidance of the offending allergen.

This guide outlines the nine major food allergens recognized by federal law, details how restaurant operations are impacted, and provides actionable frameworks to prevent cross-contact, prepare for health inspections, and implement active managerial control in commercial kitchens.

The Nine Major Food Allergens ("The Big 9")

The Federal Food, Drug, and Cosmetic Act (FD&C Act) identifies nine foods or food groups as major food allergens. This list represents the foods that account for the vast majority of severe allergic reactions in the United States.

Historically, federal law recognized eight major allergens under the Food Allergen Labeling and Consumer Protection Act of 2004 (FALCPA). However, on April 23, 2021, the Food Allergy Safety, Treatment, Education, and Research (FASTER) Act was signed into law, designating sesame as the ninth major food allergen. This change officially took effect on January 1, 2023.

The nine major food allergens, along with their common hidden sources in restaurant ingredients, include:

• Milk: Found in butter, cheese, cream, yogurt, ghee, whey, casein, and curds. It frequently hides in baked goods, batters, gravies, and processed meats.
• Eggs: Found in mayonnaise, meringue, egg wash, aioli, and lecithin. It is common in baked goods, dressings, pasta, and binders for meatball or meatloaf recipes.
• Peanuts: Found in peanut butter, peanut flour, peanut oil (especially unrefined or cold-pressed), and peanut meal. It often hides in baked goods, sauces (like mole or pesto), and international spice blends.
• Tree Nuts: Includes almonds, pecans, walnuts, cashews, hazelnuts, pistachios, macadamia nuts, and coconuts. It is found in marzipan, pesto, praline, nut butters, and extracts. Under FDA rules, the specific type of tree nut must always be declared.
• Wheat: Found in flour, bread, pasta, semolina, spelt, couscous, and wheat gluten. It is a common binder in processed foods, soups, soy sauce, and thickeners.
• Soybeans: Found in soy sauce, tofu, tempeh, edamame, soy flour, soy lecithin, and textured vegetable protein (TVP). It is frequently used in marinades, baked goods, and processed foods.
• Fish: Includes species such as bass, flounder, cod, salmon, and tuna. It is found in Worcestershire sauce, Caesar dressings, fish sauce, surimi (imitation crab), and Asian broths. Under FDA rules, the specific species of fish must be declared.
• Crustacean Shellfish: Includes crab, lobster, shrimp, prawns, and crawfish. Note that mollusks (such as clams, oysters, mussels, and scallops) are not classified as major food allergens under US federal law. It is found in seafood broths, sauces, and surimi. Under FDA rules, the specific species of shellfish must be declared.
• Sesame: Found in tahini, sesame seeds, sesame oil, sesame flour, sesame meal, and gomasio. It is common in burger buns, bagels, hummus, salad dressings, and Asian or Middle Eastern sauces.

The Highly Refined Oil Exception

Under FDA regulations and the FD&C Act, highly refined oils derived from major allergens (such as highly refined soybean oil, peanut oil, or sesame oil) are exempt from allergen labeling requirements. The high-heat refining process removes the allergenic proteins that trigger an immune response. However, cold-pressed, expeller-pressed, or crude oils are NOT exempt and must be treated as major allergens because they still contain active proteins.

Federal Law vs. State and Local Restaurant Regulations

Understanding how allergen laws apply to food service is critical. Federal law and state codes have distinct scopes of authority:

• Federal Law (FALCPA & FASTER Act): These federal statutes apply strictly to packaged foods regulated by the FDA. They require manufacturers to list allergens in plain English in the ingredient list or in a "Contains" statement. However, these laws do not directly mandate allergen listings on restaurant menus. They only apply to retail operations if a restaurant packages, labels, and offers food for sale (such as bottled house dressings or prepackaged grab-and-go salads). They do not apply to foods placed in wraps or boxes in response to an immediate customer order.
• The FDA Food Code (Model Code): The FDA publishes the Food Code every four years as a set of science-based recommendations for retail and food service operations. Although it is not federal law, state and local health departments formally adopt different editions of the Food Code as their binding state regulations.
• State and Local Amendments: States frequently introduce their own mandatory laws that go beyond the model Food Code.

Prominent State-Level Variations

Because health regulations are adopted locally, restaurant operators face significantly different legal requirements depending on their jurisdiction:

• California (SB 68 / ADDE Act): Commencing July 1, 2026, California requires food facilities that are part of a chain with 20 or more locations nationwide (the same threshold as federal calorie disclosure rules) to provide written notification of the nine major food allergens contained as ingredients in each menu item. This disclosure must be provided directly on physical menus, digital menus, menu boards, or QR-code menu experiences. If a digital format is used, an alternative method (such as a paper booklet) must be available for customers who cannot access the digital version.
• Massachusetts (Food Allergy Awareness Act of 2009): This pioneering law requires restaurants to place a mandatory menu advisory statement: "Before placing your order, please inform your server if a person in your party has a food allergy." It also mandates displaying an approved allergen awareness poster in the staff prep area and ensuring that the certified food safety manager on duty has completed an approved allergen awareness training program.
• Illinois: Since 2018, Illinois has required all certified food service sanitation managers in Category 1 (high-risk) establishments to complete ANSI-accredited allergen training.
• Other Jurisdictions: Rhode Island, Michigan, Maryland, Virginia, and New York City have various combinations of mandatory allergen posters, certified training requirements, or menu advisory notices. Additionally, New York State has passed legislation taking effect in November 2026 requiring allergen labeling on foods prepackaged on the retail premises.

2022 FDA Food Code Allergen Requirements

The 2022 edition of the FDA Food Code introduced significant updates to allergen safety and manager responsibilities:

• Addition of Sesame: The definition of "Major Food Allergen" in Section 1-201.10(B) was updated to officially add sesame as the ninth major food allergen, aligning with the FASTER Act.
• Person in Charge (PIC) Knowledge (§ 2-102.11(C)(9)): During a health inspection, the Person in Charge must demonstrate to the inspector an understanding of the foods identified as major allergens, the symptoms of allergic reactions, and the procedures to prevent cross-contact.
• Employee Training and Allergy Awareness (§ 2-103.11(O)): The PIC must ensure that all food employees are properly trained in food safety, including "food allergy awareness" as it relates to their assigned duties. This means kitchen staff must be able to describe the major allergens and identify the symptoms of a reaction.
• Unpackaged Food Notifications (§ 3-602.12(C)): The 2022 Food Code added a provision requiring retail food establishments to provide written notification to consumers of major food allergens used as ingredients in unpackaged foods. This applies to food items displayed at bakery counters, hot food lines, deli cases, or salad bars.
• Bulk Food Self-Dispensing (§ 3-602.11(C)(2)): Major food allergens must be clearly labeled on bulk food containers available for consumer self-dispensing, ensuring that guests with allergies are warned before serving themselves.

Operational Prevention of Cross-Contact

In food service, the primary operational challenge is preventing cross-contact. It is vital to understand the difference between cross-contamination and cross-contact:

• Cross-Contamination: The transfer of pathogenic bacteria or viruses to food. These biological hazards can be destroyed by cooking food to the proper internal temperature or using chemical sanitizers.
• Cross-Contact: The physical transfer of an allergen protein to a food that does not contain that allergen. Allergen proteins are not destroyed by cooking or chemical sanitizers. Once an allergen protein touches a surface or an ingredient, that item is contaminated and unsafe for an allergic guest.

To prevent cross-contact, commercial kitchens must establish strict operational barriers:

• Ingredient Verification: When raw ingredients are received, verifying intact packaging and proper labeling should be recorded on a comprehensive [food temperature log template](/resources/food-temperature-log-template/) to prevent allergen cross-contact in dry storage. Managers must review food manufacturer ingredient lists and specification sheets. Do not rely on verbal assurances or outdated sheets.
• Separated Storage: Store major allergens in sealed containers on lower shelves to prevent physical spills onto non-allergen ingredients. Label all bulk containers clearly with their allergen contents.
• Dedicated Tools (The Purple System): Use designated, color-coded prep tools—such as purple cutting boards, knives, tongs, and pans—exclusively for preparing allergen-free orders.
• Sanitation and Handwashing: Before preparing an allergen-free order, staff must wash hands, put on clean disposable gloves, and thoroughly clean and sanitize the prep surface. Note that sanitizers do not destroy proteins; surfaces must be scrubbed with soap and hot water to physically remove allergen residues. To eliminate these proteins, kitchen staff must follow a rigorous, documented [kitchen cleaning schedule](/resources/kitchen-cleaning-schedule/) that targets high-risk contact surfaces.
• Fryer Cross-Contact: Never cook allergen-free food in oil that has been used to fry allergen-containing foods (such as frying gluten-free fries in oil used for battered chicken). The allergenic proteins survive the heat of the fryer oil and will transfer to the fries.

What a Health Inspector Checks

During a routine health inspection, an environmental health officer will evaluate the kitchen's active managerial control over allergens. Inspectors typically focus on the following points:

• Manager Certification: The inspector will check that the Person in Charge holds an active, accredited Food Protection Manager certification (such as ServSafe) and can accurately answer questions about allergen symptoms and cross-contact.
• Employee Awareness: The inspector may interview random kitchen workers to confirm they understand the nine major allergens and know what to do if a guest alerts them to an allergy.
• Bulk Labeling and Signs: Sinks, bulk storage containers, and self-service areas will be inspected for proper labels. If your state requires a menu advisory, the inspector will verify that it is printed on the physical and digital menus.
• Cross-Contact Observations: Inspectors watch prep staff during service. If they observe a line cook using the same tongs for cheese and lettuce without washing hands or changing gloves, they will cite the restaurant for a critical cross-contact violation.

Common Failures and Corrective Actions

Understanding common operational failures allows managers to intervene before a violation—or a medical emergency—occurs:

Kitchen Allergen Management Checklist

Managers can use this structured checklist during daily pre-shift walkthroughs to ensure the kitchen maintains active control over allergen hazards:

Active Managerial Control with Food Ops

Active managerial control is the only way to ensure these compliance standards are met consistently across every shift. Verifying that dedicated allergen tools are properly stored and sanitized should be a non-negotiable step in your daily [restaurant line check template](/resources/restaurant-line-check-template/).

When employees "dry-lab" or fill out compliance sheets from memory, it creates a catastrophic failure point. To secure operational compliance, managers must learn how to [stop pencil-whipping checklists](/resources/stop-pencil-whipping-checklists/) and institute real-time, photo-verified audits. This is especially true for multi-location operators who must maintain uniform food safety standards across different regions with varying state laws.

With Food Ops, you can transition from paper-based logs to a dynamic, digital operations platform. Schedule daily allergen-station walkthroughs, track manager certifications, and enforce photo verification for critical sanitation checks.
