Allergen rules and the conversation at the table

Allergen rules exist because a mistake with food allergies can seriously harm or kill a guest. For most people, a meal out is a pleasure; for a guest with a severe allergy, it is an act of trust. They are trusting that the menu is accurate, that the server understood them, that the kitchen kept their food apart, and that nobody guessed. The rules set out what a venue must provide. The conversation at the table is where that information turns into a safe meal.

The legal detail varies by country, and it changes from time to time, so every venue should check the current rules with its own food safety authority. But the principles are the same almost everywhere. Accurate allergen information must exist for every dish. Guests must be able to get it, in a form they can rely on. Staff must know how to answer questions, and must never guess. And the kitchen must prepare the food as promised.

This guide sets out what must be available and in what form, how to keep an allergen matrix correct, how menu allergens should appear on paper and on screen, and the five-step conversation every server should have. It covers food safety training, what happens when the honest answer is no, and the first minutes after an allergy mistake.

A food allergy is a reaction of the immune system to a food. For some people, even a trace of the food can cause a severe reaction, including anaphylaxis, which can be fatal without prompt treatment. Unlike most food safety risks, which come from poor hygiene or storage, allergen risk comes from ordinary, wholesome food reaching the wrong guest.

That is why allergen rules focus on information and communication. The almonds in a sauce are perfectly safe for most guests and dangerous for a few. The only protection is knowing exactly what is in each dish, telling the guest truthfully, and keeping their food apart.

Across most countries, allergen rules for restaurants share four requirements. The business must know which of the listed allergens each dish contains, including in sauces, dressings, garnishes and oils. Guests must be able to get that information before they order. The information must be accurate and kept up to date when recipes or suppliers change. And staff must be able to answer questions or find someone who can.

Some rules go further, requiring written information, specific wording on menus, or training for certain staff. Check what applies where you trade, and treat the rules as the minimum rather than the goal.

In the UK and the European Union, food businesses must provide information about 14 allergens when they are used as ingredients: celery; cereals containing gluten, such as wheat, rye, barley and oats; crustaceans; eggs; fish; lupin; milk; molluscs; mustard; tree nuts; peanuts; sesame; soya; and sulphur dioxide and sulphites above a set level.

Many venues use the same list wherever they trade, because it is comprehensive and familiar to guests and suppliers. Some guests will be allergic to foods outside the list, such as kiwi or certain seeds. The rules may not require you to track those, but the conversation at the table should still catch them.

In the UK, the Food Standards Agency publishes allergen guidance for food businesses. For food that is not prepacked, such as dishes served in a restaurant, information about the 14 allergens must be available to guests. It can be given in writing, or verbally, as long as there is a clear notice telling guests how to ask, and the information given must be accurate and consistent.

Food that is prepacked for direct sale, such as sandwiches made and packed on the premises before a guest orders, must carry a full ingredient list with the allergens emphasised. Venues that sell this kind of food, such as a café counter, need to label it accordingly.

In the United States, nine foods are recognised as major food allergens: milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans and sesame. Restaurant food safety is regulated by state and local authorities, many of which base their rules on the FDA Food Code, adopted in their own way and at their own pace.

The Food Code expects the person in charge to understand the major food allergens, and some states and cities add their own requirements for staff training or menu notices. Check the rules with your local health department.

In the UAE, food safety is regulated at emirate level. In Dubai, Dubai Municipality sets the requirements for food establishments, including food safety training and the information guests must be given. Other emirates have their own authorities.

Because requirements are updated from time to time, check the current position with the authority for your emirate, and keep evidence of the training your team has done. In a city with guests from every part of the world, the conversation at the table matters even more, because guests may describe their allergies in different ways.

Guests use the word allergy for different things. A true allergy can cause a severe reaction from a trace. An intolerance, such as to lactose, usually causes discomfort rather than danger, and may depend on the amount eaten. A preference, such as avoiding onions, is a matter of taste. Coeliac disease, a reaction to gluten, is not an allergy but needs similar care with cross-contact.

Servers should not try to decide which one a guest has. Treat every stated allergy as serious, and ask questions to understand what the guest needs: is a trace a problem, or only the ingredient itself? The guest is the expert on their own condition.

At a minimum, every venue needs a complete, accurate record of the allergens in every dish, kept where staff can find it during service. Guests need a way to get the information before they order: on the menu, on a separate allergen sheet, on a digital menu, or from staff with a clear notice telling them to ask.

Written information is the safest form, because it does not depend on memory. Even where verbal information is allowed, keep a written record behind it, so that what a server says can always be checked. Our guide to allergy notes, the record that must not fail covers how to record a guest's own allergies.

An allergen matrix is a chart with every dish down one side and every allergen across the top, with a mark wherever a dish contains an allergen. It is the single source of truth for the venue. The menu, the allergen sheet, the digital menu and the server's answers should all come from it.

Build it from recipes, not memory. Every component of a dish counts: the stock in the sauce, the oil the chips are fried in, the crumb on the fish, the garnish, the bread served alongside. Our guide to building an allergen matrix that stays correct covers how to build one step by step.

A matrix is only as good as its last update. Recipes change, specials come and go, suppliers substitute products, and a new chef adds a garnish. Every one of those can change the allergens in a dish. A matrix that was right last month may be wrong tonight.

Make updating the matrix part of every change. No new dish goes on the menu until its line is complete. No supplier substitution is accepted without checking the label. One person, usually the head chef, owns the matrix and signs off every change, with the date recorded.

How menu allergens appear on the printed menu matters. Some venues mark each dish with symbols or letters for the allergens it contains; others print a note asking guests to speak to staff, with a full allergen sheet available. Both can work, as long as the information is accurate and the guest knows how to get it.

If you use symbols, explain them clearly on the same page. If you rely on a separate sheet, make sure every server knows where it is and offers it without being asked when a guest mentions an allergy. A printed menu that is out of date is dangerous, so reprint it whenever the matrix changes.

Digital and QR menus can show menu allergens for each dish and let guests filter out dishes that contain the allergens they need to avoid. That is genuinely useful, because guests can browse safely in their own time. It also keeps the information current, because a change to the dish updates the menu straight away.

Filters help guests find options; they do not replace the conversation. A filter is only as accurate as the data behind it, and it cannot know about cross-contact in the kitchen. A digital menu should always remind guests to tell their server about any allergy. Our guide to updating the menu in one place, not five covers keeping every version in step.

Some venues add a general warning that dishes may contain traces of allergens because they are prepared in a kitchen that handles them. That can be honest and useful, but it is not a substitute for knowing what is in each dish. A blanket "may contain anything" notice tells a guest with an allergy nothing they can act on.

Use precautionary warnings where there is a real, specific risk that cannot be controlled, such as a fryer shared between battered fish and chips. Tell the guest about it in the conversation, so they can decide.

Written information can tell a guest what a dish contains. It cannot tell the server what the guest needs, how severe their allergy is, or whether they are also avoiding something not on the list. It cannot reassure a nervous guest or catch the mistake when a guest misreads a symbol. Only a conversation does that.

The conversation is also what connects the guest to the kitchen. A guest's allergy written on a menu is information. The same allergy written on the order, flagged on the ticket and confirmed when the plate arrives is a safe meal.

A safe allergen conversation follows five steps, every time:

Each step is simple. The danger lies in skipping one on a busy night.

Ask every table, every time, early in the visit: "Before you order, does anyone have any allergies or dietary needs I should know about?" Do not wait for guests to raise it. Many guests with allergies are tired of explaining, or embarrassed, or assume the venue knows from their booking.

Asking every table also makes the question normal. A guest who hears it asked of the next table relaxes, because they know the venue takes it seriously.

When a guest names an allergy, listen carefully and ask what they need: "Is it all nuts, or peanuts only? Is a trace a problem, or the ingredient itself?" Write it down at once, on the order or the device, with the guest's seat if possible. Never rely on memory, even for a table of two.

Repeat it back: "So no peanuts or tree nuts, including traces, for the guest in seat two." That confirms you understood and gives the guest a chance to correct you.

Check every dish the guest is considering against the allergen matrix, or ask the chef. If you are not certain, say so: "Let me check that with the kitchen." Never guess, and never say a dish is safe because it usually is, because it does not obviously contain the allergen, or because another guest with the same allergy ate it last week.

Check the whole dish: the sauce, the garnish, the oil, the bread on the side. Many allergy incidents come from a component nobody thought to check.

The kitchen must know about the allergy before it starts cooking. Mark it on the order so it appears on the kitchen ticket, clearly and at the top. For severe allergies, also tell the chef or the pass in person. A ticket can be missed in a rush; a conversation is harder to miss.

The kitchen should confirm that it understands and can prepare the dish safely. If it cannot, the server goes back to the guest before anything is cooked. Our guide to kitchen tickets that never need a shout covers how tickets should carry allergy information.

When the dish is ready, it should be carried separately or clearly identified, so it reaches the right guest. Place it in front of the guest and confirm: "This is the dish without nuts, prepared separately." Check back after a few minutes, as you would with any table.

If anything about the dish looks different from what was agreed, such as a garnish that should not be there, take it back before the guest eats. It is far better to delay a plate than to serve a mistake.

Some phrases should never be heard in a restaurant: "It should be fine." "I think it's nut-free." "Just pick it out." "We can't guarantee anything, so it's up to you." Each one hands the risk to the guest without giving them the information they need.

Replace them with honest answers: "This dish contains nuts." "This dish doesn't contain nuts, and the kitchen can prepare it separately." "I'm not certain, so I'll check with the chef." Or, when it is true: "I'm sorry, we can't prepare this safely for you."

Many guests mention an allergy when they book. Record it on the booking and on the guest's profile, so the host sees it on arrival and the server sees it at the table. That gives the kitchen time to prepare, and it saves the guest from explaining twice.

A note on the booking does not replace the conversation. Ask again at the table: the note may be incomplete, or it may refer to another guest in the party.

In the kitchen, allergen safety depends on knowing what is in each component, keeping allergen orders apart, and cleaning between tasks. Use clean equipment, boards and utensils for allergen orders, wash hands and change gloves, and prepare the dish away from the main flow where possible.

Label containers clearly, especially for prepared components such as sauces and dressings. A sauce in an unlabelled tub is an allergy risk waiting to happen.

Cross-contact happens when an allergen gets into food that should not contain it: through shared fryers, boards, utensils, hands, or a spoon moved from one pot to another. A dish that contains no nuts in its recipe can still carry them if the cook used the same knife as for the nut crumble.

Identify the cross-contact risks in your kitchen, such as shared fryers, a grill used for marinated and plain meats, or a dessert station that handles nuts. Decide which ones can be controlled and which cannot, and tell guests honestly about the ones that cannot.

One of the most common causes of allergen mistakes is an unexpected change: a supplier sends a different brand of mayonnaise, a sauce runs out and is replaced, a chef uses a different flour. The dish looks the same, but its allergens have changed.

Check the label of every substituted product before it is used, and update the matrix if the allergens differ. If a substitution changes a dish's allergens and the matrix cannot be updated before service, take the dish off until it can.

Allergen safety is part of food safety training for everyone who handles food or talks to guests, not only for chefs. Servers need to know the allergens, how to use the matrix, the five steps at the table, and what to do if something goes wrong. Cooks need to know cross-contact controls, labelling and how to read tickets.

Train new starters before their first service, refresh everyone regularly, and keep a record of who has been trained and when. Many food safety authorities expect to see that record. The general framework of hazard analysis and critical control points is a useful way to think about where allergen risks arise.

A new server's first allergen lesson should happen before they take an order. Walk them through the matrix, explain the five steps, and have them practise the conversation with a colleague playing a guest with an allergy. Make sure they know who to ask when they are unsure, and that asking is always the right answer.

Pair new starters with an experienced colleague for their first few allergy orders. Confidence comes from doing it correctly a few times with support.

Sometimes the honest answer is that the venue cannot prepare a dish safely for a guest. A kitchen that uses nuts throughout, a shared fryer, a sauce made in advance with an allergen: each may make a dish impossible to serve safely. Saying so is not a failure; it is the most responsible thing a server can do.

Say it kindly and offer what you can: "I'm sorry, we can't make the curry safely without nuts, but the grilled fish and the salad can both be prepared for you." A guest who is told the truth will trust the venue; one who is told what they want to hear may be harmed.

If a guest reacts, or a mistake is discovered, act immediately. If the guest shows signs of a severe reaction, such as difficulty breathing, swelling of the face or throat, or collapse, call emergency services at once. If the guest has an adrenaline auto-injector, help them use it according to its instructions. Stay with the guest, keep them calm, and send someone to meet the ambulance.

Even if the guest seems fine, take any report seriously, stop the dish from being served to anyone else, and inform the manager. Our guide to an allergy mistake: the next ten minutes covers what to do in detail.

After any allergy incident or near miss, record what happened: the guest, the dish, the allergen, how the mistake occurred, and what was done. Review it with the team, without blame, to find where the process failed: the matrix, the conversation, the ticket, the kitchen or the service.

Near misses matter as much as incidents. A wrong garnish caught at the pass is a warning that the process has a weak point. Fix it before it reaches a guest.

Formats where guests serve themselves, such as buffets and brunches, carry extra risk: serving spoons move between dishes, labels get separated from food, and guests cannot ask about each item. Label every dish with its allergens, use separate utensils, and have a member of staff who can answer questions.

For events and set menus, collect allergies in advance and confirm them on the day. A guest at a wedding should not have to find the chef to ask about the sauce.

Here is an illustrative evening. A guest booking online notes a severe sesame allergy. The note appears on the booking, and the host mentions it when seating the table. The server asks every guest about allergies, confirms the sesame allergy, and asks whether traces are a problem. The guest says yes.

The server checks the matrix: the guest's chosen main has no sesame, but the bread served alongside does. The server writes the allergy on the order, tells the chef, and arranges a different side. The chef confirms the dish can be prepared separately. The plate goes out separately, and the server confirms it at the table. The guest eats safely and books again.

In servearound, each dish carries allergen tags that appear on the digital menu, where guests can filter by dietary and allergen tags, and the menu itself reminds them to tell their server about allergies. When guests order from the table, they confirm they have reviewed the allergen and dietary information and can add a note. Allergies taken with a booking are saved to the guest's profile and flagged on the booking, and the kitchen ticket carries an allergy alert with the guest's allergens, so the kitchen sees it before cooking.

When a dish has to come off because its allergens have changed, an 86 takes it off everywhere at once. servearound supports the matrix and the conversation; it does not replace them. See Menus and Order Fulfillment.

In the UK and EU, the 14 listed allergens; in the US, the nine major food allergens. Check the current rules where you trade, and treat them as the minimum.

In some places, yes, if there is a clear notice telling guests to ask and the information is accurate. A written record behind it is always safer.

A chart showing which allergens each dish contains, built from recipes and kept up to date. It is the single source of truth for the venue.

No. They help guests find options, but they cannot know about cross-contact or a guest's particular needs.

Say so honestly and offer what you can prepare safely. That is the most responsible answer.

Everyone who handles food or talks to guests, from cooks to servers to hosts.

Look after the guest first, calling emergency services for any severe reaction. Then record what happened and find where the process failed.

Every time a recipe, supplier or special changes, with a full review at least every few months.

Allergen rules require accurate information about the allergens in every dish, available to guests in a form they can rely on, and staff who can answer questions without guessing. Build an allergen matrix from recipes, keep it current with every change, and make sure the menu, the allergen sheet and the digital menu all come from it.

At the table, follow five steps: ask every table, listen and write it down, check and never guess, tell the kitchen clearly, and serve with a confirmation. Train everyone, say no when a dish cannot be made safely, and treat every near miss as a warning. Written information keeps a venue compliant; the conversation keeps guests safe.
