Allergen Safety at Brooklyn Restaurants — Your Rights and What to Ask

The Federal Allergen Framework

Food allergen declaration in the United States is primarily governed by two federal laws:

• FALCPA (Food Allergen Labeling and Consumer Protection Act, 2004) — requires that packaged food labels clearly declare the top eight allergens: milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, and soybeans.
• FASTER Act (Food Allergy Safety, Treatment, Education, and Research Act, 2021) — added sesame as the ninth major allergen, effective January 1, 2023. Sesame must now be declared the same way as the original eight.

These laws apply to packaged food labels. Restaurant food is not required by federal law to follow the same labeling rules, but New York City has its own requirements that apply to food service establishments, and many restaurants voluntarily provide allergen information.

The Nine Major Allergens (2026)

1. Milk — includes butter, cream, cheese, yogurt, and lactose-containing ingredients
2. Eggs — including egg-based products used in baked goods, sauces, and batters
3. Fish — including anchovies (frequently present in Caesar dressing and Worcestershire sauce)
4. Shellfish — shrimp, crab, lobster, and related species
5. Tree nuts — almonds, cashews, walnuts, pecans, pistachios, and others (each variety counts separately)
6. Peanuts — a legume, separate from tree nuts
7. Wheat — found in flour, pasta, bread, coatings, and many sauces
8. Soybeans — found in many Asian sauces, tofu, edamame, and some salad dressings
9. Sesame — including sesame oil, tahini, and sesame seeds used as a topping or coating

These nine represent the allergens responsible for approximately 90% of serious allergic reactions in the United States. That said, any food protein can theoretically cause an allergic reaction in a sensitized individual.

NYC Menu Labeling Rules

New York City has historically maintained strong public health standards around restaurant food transparency. Key provisions relevant to allergen safety include:

• NYC Health Code requires that restaurant staff be able to identify ingredients in food items when a customer with a known food allergy asks. This means the kitchen must have documentation of ingredients available — not just verbal assurances from a server who may not know the formulation.
• Chain restaurants in NYC with 15 or more locations nationwide are required to post calorie counts on menus; some also voluntarily list common allergens on menus or via digital tools.
• The NYC DOHMH Food Protection Certificate — required in every food service establishment — includes allergen awareness as part of the curriculum.

What to Ask Your Server — Practically

The most effective approach when dining with a food allergy is clear, specific communication. Vague requests are more likely to be misunderstood. Effective questions include:

• "I have a [specific allergen] allergy. Can you check whether this dish contains [allergen] or is prepared with shared equipment?"
• "Does your kitchen use [peanut oil / sesame oil / shellfish-based stock] in sauces or cooking fats?"
• "Is this dish made on shared surfaces or with shared utensils used for [allergen]?"
• "Can you please let the kitchen know about my allergy before the order is prepared?"

Asking to speak with the manager or chef directly is entirely appropriate in an allergen situation. A well-run establishment welcomes this conversation.

Hidden Sources of the Nine Allergens

Many allergens appear in unexpected places in restaurant cooking:

• Milk: Butter used to finish sauces, cream in soups, milk solids in mashed potatoes
• Eggs: Caesar dressing (traditional recipe uses raw egg), fresh pasta, hollandaise, glazes
• Fish: Worcestershire sauce (contains anchovies), some Asian fermented pastes
• Wheat: Coatings on fried food, thickeners in sauces, soy sauce (most soy sauce contains wheat)
• Sesame: Tahini in hummus, sesame oil used as a finishing flavor, sesame in burger bun seeds
• Peanuts: Satay sauces, some mole preparations, oils used for frying in some cuisines

Cross-Contact Risk

Cross-contact occurs when an allergen is unintentionally transferred to a food that is not supposed to contain it — through shared fryers, surfaces, utensils, or preparation sequences. This is distinct from cross-contamination in the microbial sense (see the cross-contamination article in this series).

Asking whether the kitchen operates a dedicated allergen-free zone or uses dedicated equipment for allergen-sensitive orders is reasonable. Many Brooklyn restaurants, particularly those with experienced front-of-house teams, have protocols for this. Not all do.

Filing a Concern

If a restaurant misrepresents its ingredients or fails to respond appropriately to an allergen inquiry, you can file a complaint through 311. DOHMH takes allergen-related complaints seriously, particularly in cases where a customer experienced a reaction they believe was caused by an undisclosed ingredient.

Frequently Asked Questions

Are NYC restaurants required to list allergens on their menus?

Chain restaurants with 15 or more locations are required to post calorie information; full allergen listing is not universally required for restaurant menus. However, kitchen staff must be able to identify allergens in dishes upon request under NYC Health Code.

Is sesame now considered a major allergen?

Yes. The FASTER Act, effective January 1, 2023, added sesame as the ninth major allergen under federal law. Packaged food labels must declare sesame; restaurants should be able to identify it in their dishes.

What is the difference between a food allergy and a food intolerance?

A food allergy involves an immune system response that can cause severe or life-threatening reactions (anaphylaxis). A food intolerance is a digestive response that is generally uncomfortable but not life-threatening. Restaurants should treat declared allergies with full seriousness regardless of the distinction.

Can I trust a restaurant's claim that a dish is allergen-free?

Ask specific questions about ingredients and cross-contact rather than relying on a general declaration. Verify with the manager or chef, and consider whether the kitchen environment allows for meaningful allergen separation given its size and volume.
