What to do immediately when a guest may have eaten an allergen, what to record while it is fresh, and the review the following day that must actually happen.

An allergy mistake is every restaurant's most serious kind of error. A guest who told the team about an allergy is served a dish containing it, or a dish that was cross-contaminated, or a dessert that nobody checked. Sometimes the guest notices before eating. Sometimes they notice after the first bite. Sometimes they have a reaction. What the team does in the next ten minutes matters more than anything else that happens that night.

This is not a moment for service recovery in the usual sense. A free dessert does not put right an allergic reaction. The priorities are the guest's safety first, calm and clear action second, and accurate records third. Only after that does the venue turn to apologising, understanding what went wrong and making sure it never happens again.

This guide sets out what to do immediately when an allergy mistake happens, minute by minute, what to record while it is fresh, how to look after the guest and the team, and the review the following day that must actually happen. It is practical guidance for a venue, not medical advice. Every venue should have its own emergency procedure, agreed in advance and practised, and should follow the rules and guidance that apply where it trades.

Why the first minutes matter

Allergic reactions can develop quickly, and some can become serious within minutes. The general entry on food allergy describes how reactions range from mild symptoms to anaphylaxis, which is a medical emergency. A team that recognises the situation, takes it seriously and acts at once gives the guest the best chance.

The first minutes also shape everything afterwards. A team that panics, argues, hides the mistake or waits to see what happens makes the situation worse, for the guest and for the venue. A team that responds calmly and quickly, following a plan, shows the guest and everyone around them that the venue takes their safety seriously.

That is why the plan must exist before it is needed. Nobody should be working out what to do while a guest is unwell.

Minute one: stop and take it seriously

The moment anyone realises an allergy mistake may have happened, whether a guest says their dish contains something they are allergic to, a cook realises the wrong plate went out or a server notices a garnish that should not be there, stop. Remove the dish from the guest, if they have not finished it. Take the concern seriously, whatever the guest's symptoms or lack of them.

Do not argue about whether the allergen is really in the dish, and do not suggest the guest is overreacting. If there is any chance a guest has eaten their allergen, treat it as real until you know otherwise.

Tell a manager immediately. One person should take charge, so the response is calm and coordinated rather than several people giving different instructions.

Minute two: ask and watch

Ask the guest, calmly, how they are feeling and whether they have any symptoms. Ask whether they have an allergy plan and carry their own medication, such as an adrenaline auto-injector, and whether they need help using it. Follow the guest's lead and your first-aid training; many people with serious allergies know exactly what they need.

Watch for signs that the reaction is becoming serious, such as difficulty breathing, swelling of the face, lips or throat, feeling faint, or the guest saying they feel very unwell. Do not wait for symptoms to become severe before acting.

Keep the guest calm and comfortable, and keep someone with them at all times. Do not let a guest who may be having a reaction go to the toilet or outside alone.

Minute three: call for help if there is any doubt

If there are any signs of a serious reaction, or the guest asks for help, call the emergency services at once. Give the address clearly, say that a guest may be having a severe allergic reaction, and follow the instructions you are given. Send someone to the door to meet the ambulance and guide the crew in.

If in doubt, call. It is far better to call for help that turns out not to be needed than to wait too long. Your venue's emergency procedure should make clear who makes the call and that nobody needs permission to make it.

If the guest's symptoms are mild and they say they are fine, still keep watching them closely, because reactions can develop over time. Make sure they know to seek medical help if anything changes after they leave.

Minutes four to six: keep the dish and the details

While the guest is being looked after, another member of the team should secure the evidence. Keep the dish, or what is left of it, set aside and untouched. Keep the ticket, the order and any notes that came with it. Set aside the packaging and labels of the ingredients used in the dish, including garnishes, sauces and anything added at the pass.

These details will be needed to understand what happened, both for the guest's medical care, if a doctor asks what was eaten, and for the venue's review. They are also important if the incident must be reported to a food safety authority.

Do not throw anything away, clean the station before checking it, or change the records.

Minutes six to eight: check the rest of the service

An allergy mistake may not be isolated. If the wrong ingredient was used in a sauce, a batch of a dish, or a shared garnish, other guests may have received it too. Check quickly whether any other orders could be affected, especially for guests with the same allergy.

If there is a risk to other guests, stop serving the affected dish or component until it is checked. Tell the floor, so servers do not recommend or serve it. Our guide to 86 an item so nobody orders it at five past covers taking a dish off every menu at once.

Minutes eight to ten: look after the table

The guest's companions will be worried, and other tables may have noticed. Keep the guest's table informed and calm. Offer them privacy if they want it, and help with practical things: a quiet space, a taxi or a call to someone.

Do not discuss blame, compensation or what went wrong at this stage. Show care, keep them informed and make sure they have what they need. If the guest goes to hospital, offer to help their companions, and make sure the venue has a way to contact the guest later, if they are willing.

For the rest of the room, keep service going calmly. Other guests should see a team that is handling a difficult moment well.

What to record while it is fresh

As soon as the immediate situation is under control, record what happened, while memories are fresh. Write down the time, the table, the guest's allergy as they described it, what they ordered, what they were served, who took the order, who prepared the dish, who checked it at the pass and who served it. Note what the guest said, what symptoms they had, what help was given and whether emergency services were called.

Record what each member of staff remembers, separately and factually. Do not speculate about fault in the record; describe what happened. Keep the record secure and private.

These allergy notes, the record of the incident, will be the basis of the review and of any report the venue needs to make.

When the guest says they are fine

Many guests who realise they have eaten their allergen will say they are fine, often out of embarrassment or a wish not to cause a fuss. Some genuinely are; others are not yet showing symptoms. Respect what the guest says, but do not take it as the end of the matter.

Keep checking on them quietly, make sure someone is nearby, and remind them that the venue will help immediately if anything changes. Before they leave, make sure they know how they would get help if symptoms develop later, and that they are not travelling alone if they feel at all unwell.

Record what the guest said and when, so the record is accurate whatever happens afterwards.

Children and guests who cannot speak for themselves

Children, and guests who cannot easily describe what they feel, need extra care. A child may not recognise or explain the early signs of a reaction, and a parent may be the first to notice. Listen to parents and carers closely, and act on their concern without waiting for the child to say they feel unwell.

The same applies to any guest who has difficulty communicating. When in doubt, call for help.

Reporting the incident

Depending on where you trade and what happened, you may need to report an allergy incident to your local food safety authority, your insurer or both. Some authorities expect to be told about allergic reactions linked to food served by a business. Find out in advance what applies to you, and include it in your procedure.

In the UK, for example, the Food Standards Agency's allergen guidance for food businesses sets out businesses' responsibilities for allergen information and safety; other countries have their own authorities and rules.

Be honest and cooperative with any authority that investigates. A venue that reports promptly and shows that it has a clear procedure is in a far better position than one that hides an incident.

Contacting the guest afterwards

If the guest is willing, contact them after the incident to ask how they are, to apologise sincerely and to explain what the venue is doing to understand what went wrong. Do it personally, usually through the manager or owner, and with care. Some guests will want to talk; others will not, and that must be respected.

Do not pressure the guest or ask them not to discuss what happened. Do not make offers that look like an attempt to buy silence. If the incident could lead to a legal claim, take advice on what to say, but do not let that stop you from showing genuine care.

Service recovery after an allergy mistake is about trust, not compensation. The guest needs to know that the venue took it seriously and will make sure it does not happen to anyone else.

Looking after the team

An allergy incident is distressing for the team, especially for the person who took the order, prepared the dish or served it. They may feel guilty, frightened or defensive. After the immediate situation is dealt with, check on them.

Make it clear that the review will focus on what went wrong in the process, not on blaming individuals. Staff who fear blame are less likely to be honest about what happened, and honesty is what the review needs.

If someone made a mistake, address it fairly and privately, with support and training rather than humiliation.

The review the following day

The most important part of the response happens the next day: a review that actually takes place, with the people who were involved and the people who can change the process. It must not be postponed until everyone has forgotten. Its purpose is to find out exactly where the allergy was lost and to fix that point so it cannot fail again.

Trace the allergy through every handover: was it recorded at booking? Was it on the guest's profile? Did the host pass it on? Did the server ask at the table and record it on the order? Did it appear clearly on the kitchen ticket? Did the cook check the allergen matrix? Was anything added at the pass? Was the plate marked and served to the right seat? Our guide to allergy notes: the record that must not fail covers each handover.

Find the point where it failed, and agree a specific change.

Common causes to check

The review often finds one of a few common causes. The allergy was mentioned at booking but never reached the server. The server knew but did not record it on the order. The ticket showed it, but not prominently enough. The allergen matrix was out of date after a recipe or supplier change. A garnish or sauce was added at the pass that was not in the recipe. Plates were mixed up at the table.

Each has a fix. A booking note that does not reach the floor needs the allergy to follow the guest to the table. A ticket that does not stand out needs a clearer design. An out-of-date matrix needs a process for updating it whenever a recipe or supplier changes. Our guide to building an allergen matrix that stays correct covers the record behind the menu.

Changing the process

Once the cause is found, change the process, not just the person. Retraining one server may help, but if the process allowed the allergy to be lost, the next new server will lose it too. Make the change in the system: how allergies are recorded, how they are shown, how dishes are checked, how plates are marked.

Write the change down, train every relevant member of staff on it, and check that it is being followed in the weeks afterwards. Then trace a few allergy orders through the new process to confirm it works.

Practising the procedure

An emergency procedure that has never been practised is likely to fail under pressure. Practise it, as you might practise a fire drill: walk through what happens when a guest says they have eaten their allergen, who takes charge, who calls for help, who looks after the guest, who secures the dish and who records what happened.

Include it in training for every new member of staff, and refresh it regularly. Make sure everyone knows where the procedure is written down, how to call emergency services and the venue's address.

A worked example

Here is an illustrative incident and response. The details are examples, and every venue's procedure will differ.

  • A guest with a sesame allergy, recorded at booking, takes a bite of a salad and says it tastes of sesame. The server removes the plate and calls the manager.
  • The manager takes charge, asks the guest how they feel, and asks whether they have their own medication. The guest says their lips feel tingly. The manager calls the emergency services straight away, and a colleague meets the ambulance at the door. Another colleague sets aside the salad, the ticket and the labels.
  • The guest is taken to hospital as a precaution and later recovers. The manager records what happened that evening, with each member of staff's account.
  • The next day's review finds that the allergy was on the ticket, but the salad was finished at the pass with a seed mix from a new supplier that contained sesame, and the matrix had not been updated. The process changes: every finishing touch is written into recipes, new supplier products are checked before use, and the pass checks every allergy plate against the matrix.

Common mistakes after an allergy mistake

  • Waiting to see whether symptoms develop before calling for help.
  • Arguing about whether the allergen was really in the dish.
  • Leaving the guest alone.
  • Throwing away the dish or cleaning the station before checking.
  • Not checking whether other guests were affected.
  • Discussing fault or compensation at the table.
  • Postponing the review until it is forgotten.
  • Retraining one person instead of fixing the process.

Where servearound fits

servearound does not replace a venue's emergency procedure or its kitchen's allergen controls. What it gives the review the next day is a clear record. Allergies saved to the guest show on their booking, on the table and on the kitchen ticket, and the check records exactly what was ordered, for which seat, with which options and notes, and what reached the kitchen on the ticket, so the review can trace where the allergy was shown and where it was lost.

Each dish carries its allergens and ingredients in one library behind every menu, and a dish can be taken off every menu and terminal at once if a component may be affected. See fulfillment and the guests module.

Questions operators ask

When should we call the emergency services?

At once, if there are any signs of a serious reaction or the guest asks for help. If in doubt, call.

Should we wait to see if symptoms develop?

No. Take it seriously immediately, keep watching the guest closely and act at the first sign of a serious reaction.

Who should take charge?

One person, usually the most senior manager present, so the response is calm and coordinated.

What should we keep?

The dish, the ticket, the order and the labels of every ingredient used, untouched.

Do we have to report it?

That depends on where you trade and what happened. Find out in advance and include it in your procedure.

What must the review find?

The exact handover where the allergy was lost, and a change to the process that stops it happening again.

Should we tell the rest of the team?

Yes, once the facts are clear. Share what went wrong in the process and what has changed, without blaming individuals, so everyone learns from it.

The short version

An allergy mistake demands calm, fast action. In the next ten minutes: stop and take it seriously, ask how the guest feels and watch closely, call the emergency services at the first sign of a serious reaction, keep the dish and the details, check whether other guests are affected and look after the table. One person should take charge, and the procedure should already exist and have been practised.

Afterwards, record what happened while it is fresh, report it where required, contact the guest with genuine care, support the team and hold the review the following day. Trace the allergy notes through every handover, check the allergen matrix, find exactly where it failed, and change the process so food safety does not depend on one person getting it right.
