Menu allergen statements are the notes a restaurant prints on a menu, table tent, chalkboard or website to tell you which dishes contain common allergens. In much of the United States they exist because the model FDA Food Code asks food businesses to tell customers in writing about major food allergens in food that is not packaged, but whether that applies to a given restaurant depends on what its state or county has adopted. A statement is useful, yet it mostly describes ingredients. It says far less about how a dish is handled, which is why it works best alongside a direct conversation with the staff.
Key takeaways
- The US recognizes nine major food allergens, and sesame became the ninth on January 1, 2023.
- The model Food Code asks for written allergen notice on unpackaged food, but only where a state or local agency adopts it.
- Federal allergen labeling for packaged food largely does not reach dishes made to order.
- “May contain” and “gluten-free” are different kinds of statement, so ask how a dish is prepared.
- If you have a diagnosed food allergy, a clinician is the right person to help you plan for eating out.
Myth 1: Every restaurant must print menu allergen statements
Fact: it depends on where you are eating. The FDA’s summary of the 2022 Food Code allergen changes says establishments should give consumers written notification of major food allergens in unpackaged food. Accepted forms include brochures, deli case or menu notices, label statements, table tents and placards. The same page is plain that the model Food Code is not federal law or regulation: it applies only where a jurisdiction adopts it. Our walkthrough of how the FDA Food Code is turned into local rules explains that adoption step.
Local agencies then add their own guidance. The Illinois Department of Public Health, for example, says in its allergen FAQ that written notification can be physical or electronic, that specials follow the same rule as the regular menu, and that a QR code is allowed, although businesses should consider whether it suits their guests and offer a physical copy on request.
The federal packaged-food law is a separate thing. The FDA notes that its allergen labeling rules cover most packaged foods, but they exclude most foods sold at retail or food service that are not prepackaged with a label, and they do not apply to food put in a wrapper or container after you order it. That gap is exactly what menu notices are meant to fill.
Myth 2: The allergen list is the same in every country
Fact: the lists differ. In the US, the nine major food allergens are milk, eggs, fish, crustacean shellfish, tree nuts, wheat, peanuts, soybeans and sesame. The UK Food Standards Agency’s allergen guidance for food businesses, which applies in England, Wales and Northern Ireland, names 14.
| Allergen group | US major food allergens | UK list of 14 |
|---|---|---|
| Milk, eggs, fish, peanuts, sesame, soybeans, tree nuts | Yes | Yes |
| Crustacean shellfish | Yes | Yes |
| Molluscs such as mussels and squid | No | Yes |
| Wheat | Yes | Covered under cereals containing gluten |
| Celery, lupin, mustard | No | Yes |
| Sulphur dioxide and sulphites above ten parts per million | No | Yes |
The UK rules for food that is not prepacked are also specific. A business must provide allergen information for every item containing any of the 14. It may do so verbally, but only if a written notice in a clearly visible place explains how customers can get that information. If you travel, read each country’s menu notice on its own terms.
Myth 3: “May contain” means the dish was tested
Fact: a precautionary line is a warning about risk, not a lab result. For packaged foods, the FDA says advisory statements such as “may contain” or “produced in a facility that also uses” are not required by law. Manufacturers may use them for unavoidable cross-contact, but they must be truthful and not misleading, and they should not replace good manufacturing practice.
Restaurants work in shared spaces too. The FSA guidance says that if a business cannot avoid cross-contamination while preparing a dish, it should tell customers it cannot provide an allergen-free version. When a menu says a kitchen “handles nuts” or “cannot guarantee” a dish is free from an allergen, read it as that kind of honest notice. It tells you the risk exists. It does not tell you how large it is.
Myth 4: “Gluten-free” on a menu means the same as on a package
Fact: only packaged food is directly bound by the federal definition. The FDA explains that a gluten-free label on a packaged food means it contains less than 20 parts per million of gluten, and that ingredients made from wheat, rye or barley are not allowed unless they have been processed to bring the food under that level. For restaurants, the FDA says menu claims “should be consistent” with that definition, while state and local governments oversee restaurants directly.
The FDA’s own advice to diners is practical: ask what the restaurant means by “gluten-free”, which ingredients it uses, and how the item is prepared. Shared fryers, toasters and pasta water are the kind of detail a printed line rarely covers.
Myth 5: Once the menu has a statement, you do not need to speak up
Fact: written notice and staff knowledge are meant to work together. The FSA says written information supported by a conversation works best for customers. On the US side, the FDA notes that the Food Code’s training sections expect food safety training to include food allergy awareness covering all nine major allergens. Our guide to what new servers learn in training shows where that fits in a new hire’s first weeks.
Assumptions about diet labels can also mislead. The FSA warns that customers often assume vegan meals are free from egg, fish, crustaceans, molluscs and milk, which is not always the case, because low-level cross-contamination can happen during production. A dish can be vegan by recipe and still not be suitable for someone with a milk allergy.
Frequently asked questions
Where do I usually find menu allergen statements?
Look at the foot of the menu, on a separate allergen chart, on a table tent or board near the counter, or behind a QR code. If you cannot find one, ask a server or manager whether the restaurant keeps allergen information for its dishes.
Do daily specials need allergen information too?
Under the Illinois guidance, yes: specials follow the same written-notice rule as the regular menu. Elsewhere it depends on the local code, so ask about specials directly, because they change more often than the printed menu.
What should I do if I have a serious food allergy?
Talk to your doctor or another clinician about how to manage eating out safely. When you order, tell staff about the allergy clearly, ask how the dish is prepared, and choose another option if the answers are unclear.
How to read the next menu you pick up
Treat the allergen note as the first step. Check which allergens it lists, notice any “may contain” or “cannot guarantee” wording, and then ask how your dish is made. If you want to see how inspectors check allergen labels and the rest of a kitchen’s paperwork, read our checklist of what health inspectors look for, or browse more menus and standards guides.
