Menu Safety Glossary and FAQ Hub
Plain-language definitions of the allergen, nutrition, and menu terms operators run into, followed by answers to the questions we hear most often.
- Allergen
- A substance, almost always a protein in food, that triggers an immune response in a sensitized person. Reactions range from mild hives to anaphylaxis, and the amount needed to cause a reaction can be very small.
- Allergen awareness training
- Structured training that teaches staff to recognize major allergens, prevent cross-contact, handle a guest's allergy request, and respond to a reaction. Several states require a manager to complete an approved course, and the FDA Food Code expects all food employees to be trained on allergens.
- Allergen matrix
- A grid listing every menu item against each tracked allergen, marking which items contain it. It is the most common written allergen record in restaurants and is only as reliable as the recipe and supplier data behind it.
- Anaphylaxis
- A severe, rapid, potentially life-threatening allergic reaction that can affect breathing, circulation, and multiple body systems at once. Epinephrine is the first-line treatment, and emergency services should be called whenever it is suspected.
- Celiac disease
- An autoimmune condition in which eating gluten damages the small intestine. It is not an IgE allergy, but it requires the same strict avoidance of wheat, barley, and rye, and the same attention to cross-contact in the kitchen.
- Cross-contact
- The transfer of an allergen from one food or surface to another, for example through shared fryer oil, unwashed utensils, or airborne flour. Unlike bacteria, allergen proteins are not destroyed by cooking, so heat is not a control.
- Cross-contamination
- The transfer of harmful microorganisms between foods or surfaces, most often from raw to ready-to-eat food. Many kitchens use the term loosely to include allergen transfer, but the controls differ, which is why allergen professionals prefer the separate term cross-contact.
- Crustacean shellfish
- Shrimp, crab, lobster, crawfish, and related species. Crustacean shellfish is one of the nine federally recognized major allergens; molluscan shellfish such as clams, oysters, mussels, and scallops are not on the federal list but still cause reactions and are worth tracking.
- Dedicated fryer
- A fryer whose oil is used only for foods free of a particular allergen, most often wheat or shellfish. Without one, anything cooked in shared oil should be treated as containing whatever else has been fried in it.
- Epinephrine auto-injector
- A single-use device that delivers a measured dose of epinephrine to treat anaphylaxis. Guests with severe allergies often carry one, and staff should know to call emergency services and help the guest use their own device rather than delay.
- FALCPA
- The Food Allergen Labeling and Consumer Protection Act of 2004, which requires packaged foods regulated by the FDA to declare the major food allergens in plain language. It governs product labels rather than restaurant menus, but supplier labels built under it are the raw material for a restaurant's allergen record.
- FASTER Act
- The Food Allergy Safety, Treatment, Education, and Research Act of 2021, which added sesame to the list of major food allergens for labeling purposes, effective at the start of 2023. It brought the federal list from eight allergens to nine.
- FDA Food Code
- A model code published by the FDA that states and localities adopt, often with modifications, as the basis for restaurant health regulation. It includes requirements that the person in charge and food employees understand major allergens and how to prevent cross-contact.
- Food intolerance
- An adverse reaction to food that does not involve the immune system, such as lactose intolerance. Symptoms are usually digestive and not life-threatening, but guests still rely on accurate ingredient information, and a kitchen should treat a stated intolerance seriously.
- Gluten-free claim
- A statement that a food contains gluten below the threshold set by FDA regulation for packaged foods. Restaurants that describe a dish as gluten-free are expected to meet the same standard, which means controlling ingredients and cross-contact, not just leaving out bread.
- An allergen present in a dish where a guest would not expect it, such as fish in Worcestershire sauce, tree nuts in pesto, wheat in soy sauce, or milk in some breads and seasoning blends. A good allergen record surfaces these so servers do not have to rely on intuition.
- Ingredient statement
- The written list of ingredients and allergen declarations provided by a manufacturer or supplier for a product. Keeping a current statement on file for every item that enters the kitchen is the foundation of an accurate allergen record.
- A digital menu reached through a permanent QR code and generated from a central record each time it loads. Because the code never changes and the content behind it is drawn from the current record, updates reach guests without reprinting anything.
- Major food allergens
- The nine allergens recognized under US federal labeling law: milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, and sesame. They are often called the Big Nine and are the minimum any restaurant allergen program should track.
- The federal requirement that chain restaurants with twenty or more locations under the same name and substantially the same menu post calorie counts on menus and menu boards, display a statement about daily calorie intake, and provide additional written nutrition information on request.
- Nutrition analysis
- The calculation of calories and nutrients for a dish from its recipe, ingredient quantities, and yields, using ingredient databases or laboratory testing. Figures are estimates based on standard preparation and should be re-run whenever a recipe or supplier changes.
- Person in charge
- The FDA Food Code term for the individual responsible for the operation during a given shift. The person in charge must be able to describe the major allergens, the symptoms of an allergic reaction, and the steps the kitchen takes to prevent cross-contact.
- Precautionary allergen labeling
- Voluntary statements on packaged foods such as 'may contain' or 'processed in a facility that also handles'. They are not standardized in the US and do not indicate how likely contamination is, so a restaurant should decide in advance how to treat products that carry them.
- Recipe spec sheet
- A standardized document for a dish that lists every ingredient with quantity, the supplier item used, preparation steps, plating, and derived allergen and nutrition data. It is the working record that both the kitchen and the menu should be built from.
- Sesame
- The most recently added federal major allergen. It appears in obvious forms like seeds and tahini and in less obvious ones like some breads, spice blends, and oils, which is why many restaurants had to revisit their allergen records after it was added.
- Single source of truth
- The principle that allergen and nutrition data should be maintained in exactly one place and that every menu, website, printed card, and delivery listing should be derived from it. It is the practical answer to the copy problem, where multiple independently maintained versions inevitably disagree.
- Static QR code
- A QR code that links directly to a fixed file, usually a PDF. Changing the menu means uploading a new file and, if the link changes, printing new codes, so a static code offers no accuracy advantage over paper.
- Sulfites
- Preservatives used in wine, dried fruit, some shrimp, and processed potatoes that can trigger reactions, especially in people with asthma. Packaged foods must declare them above a regulatory threshold, and sulfites are worth tracking even though they are not on the federal major allergen list.
- Supplier substitution
- A change in the product delivered against an order, either because the distributor sent an alternative or because the manufacturer reformulated. Substitutions are a leading cause of allergen records going wrong without anyone noticing, so deliveries should be checked against the record.
- Tree nuts
- A group of nuts including almonds, walnuts, pecans, cashews, pistachios, hazelnuts, and others, treated as one major allergen category under federal law. Peanuts are legumes and are a separate allergen, though many guests are allergic to both.
Questions people ask
What are the nine major food allergens in the United States?
Milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, and sesame. Sesame is the newest addition and has been treated as a major allergen since the start of 2023. These are the minimum a restaurant should track, but molluscan shellfish, mustard, sulfites, and others also affect real guests.
Are restaurants legally required to list allergens on the menu?
Federal packaged-food labeling law does not require restaurant menus to list allergens. Obligations come from the FDA Food Code as adopted by each state and from state and local rules, some of which require a menu notice asking guests to inform staff of allergies and require allergen training for a manager. Check your own state and local code, and treat the strictest rule that applies to you as the baseline.
Which restaurants must show calorie counts on their menus?
Federal menu labeling applies to restaurants and similar retail food establishments that are part of a chain with twenty or more locations under the same name offering substantially the same menu. Those businesses must post calories on menus and menu boards, display a daily calorie intake statement, and provide fuller nutrition information on request. Smaller operators are generally not covered but can opt in voluntarily.
What is the difference between a food allergy and a food intolerance?
A food allergy is an immune system response to a food protein and can cause anaphylaxis. An intolerance, such as lactose intolerance, does not involve the immune system and usually causes digestive discomfort. Celiac disease is a third category, an autoimmune condition triggered by gluten. All three require accurate ingredient information, but the kitchen's cross-contact controls are most critical for allergies and celiac disease.
How often should a restaurant review its allergen information?
At every menu change, whenever a recipe or supplier item changes, and on a fixed calendar cadence in between, typically a few times a year. The review should compare each dish against its current recipe and the ingredient statements on file. Reviews that only happen when someone remembers are the reason so many allergen cards are wrong.
Can a restaurant call a dish gluten-free if it uses a shared fryer?
It should not. A gluten-free claim implies that the dish meets the regulatory definition, which shared oil that has fried breaded items cannot support. The honest approach is to describe the dish as prepared without gluten-containing ingredients, state that fryers are shared, and let the guest decide with full information.
What should a server do when a guest mentions an allergy?
Acknowledge it, write it on the ticket in the agreed format, check the current allergen record instead of relying on memory, involve the kitchen or a manager if anything is unclear, and confirm with the guest exactly what will be modified. Avoid phrases like 'completely safe' unless the kitchen has explicitly confirmed a dedicated preparation.
Is a QR code menu safer than a printed allergen card?
Only if the code points at a menu generated from a maintained central record. A QR code that links to a static PDF goes stale exactly like paper. The safety comes from having one source of truth and a process for updating it, not from the code itself.
How should a kitchen handle supplier substitutions?
Check every delivery against what was ordered, pull the ingredient statement for any substitute before it is used, and update the allergen record if anything changed. If a statement cannot be obtained quickly, hold the product or pull the affected dishes rather than assuming the substitute matches the original.
What should a menu say about cross-contact?
It should state plainly what the kitchen can and cannot guarantee, for example that fryers are shared or that nuts are used throughout the kitchen, and invite guests with allergies to speak to staff. A clear, honest statement builds more trust than a vague disclaimer and gives servers a consistent script to follow.
Who should own allergen information in a restaurant?
One named person, usually the chef or a kitchen manager, with the authority to pull a dish from service until its data is confirmed. Shared ownership tends to mean no ownership. That person maintains the record, reviews deliveries and recipe changes, and signs off on what the menu and the servers say.
Do delivery platform listings need the same allergen information?
Yes, as far as the platform allows. A guest ordering for delivery cannot ask a server, so the listing and any attached notes are the only information they have. Delivery listings are also one more copy of the truth to keep in sync, which is a strong argument for deriving them from the same central record as the in-house menu.
What should staff do if a guest has an allergic reaction in the restaurant?
Call emergency services immediately if there is any sign of a severe reaction such as difficulty breathing, swelling, or dizziness, and help the guest use their own epinephrine auto-injector if they carry one. Do not wait to see if symptoms improve. Afterward, record what was ordered and served so the cause can be identified and the record corrected.
