How to Handle Customer Allergen Requests (FOH)

What Should You Ask the Customer?

Key takeaway: Ask only the questions needed to identify the allergen and process the order accurately.

The conversation should be clear, respectful and focused. Staff do not need the customer’s medical history, but they do need enough information to avoid misunderstanding.

Useful questions include:

• “Which food or allergen do you need to avoid?”

• “Are there any other allergens we should record?”

• “Which dish are you considering?”

• “Would you like me to check the ingredients and preparation process with the kitchen?”

• “Are you ordering any sides, sauces, drinks or garnishes that should also be checked?”

Where a customer uses a broad term such as “nuts”, staff should clarify what the customer means rather than narrowing the request themselves. Peanuts and the tree nuts listed in Annex II are separate regulated allergen categories, and different dishes may contain different members of the nut group.

Staff should record the customer’s own description accurately. They should not replace it with a shorthand term that could change its meaning.

Questions Staff Should Avoid

Staff should not ask questions that transfer the business’s responsibility back to the customer, such as:

• “Can you tolerate a small amount?”

• “Is it a serious allergy?”

• “Have you eaten here before without a problem?”

• “Would it be safe if we removed the garnish?”

• “Do you think the fryer will be okay?”

These questions encourage speculation. The correct approach is to check what the dish contains, how it is prepared and whether the business can control the relevant cross-contact risk.

Checking the Matrix, Recipe and Kitchen

Key takeaway: Verify the answer using current written information and the actual preparation process—not staff memory.

An allergen matrix is an important starting point, but it should not be treated as the only source of truth. The staff member or designated checker should confirm that the matrix is current and consistent with the recipe, supplier information and kitchen practice.

The verification process should cover:

Regulation (EU) 2021/382 amended the EU food-hygiene framework to strengthen food-allergen management. Among other requirements, equipment and containers used with allergenic materials must not be used for food that does not contain that allergen unless they have been cleaned and checked for visible residues. The same framework requires appropriate food-safety awareness, supervision and training.

When the Answer Cannot Be Verified

When information is incomplete, contradictory or outdated, staff should not improvise.

The correct response is:

“I’m sorry, but we cannot verify this dish confidently enough to recommend it for your allergy. Let me check whether there is another option we can assess more reliably.”

A refusal to make an unsupported assurance is safer and more professional than a confident guess.

Communicating with the Kitchen

Key takeaway: Pass the allergy request directly, visibly, and through the approved order system.

Allergy information can be lost when it passes through several people. Businesses should therefore establish a standard communication route from the customer to the kitchen and back again.

A strong process includes:

1. Marking the order clearly as an allergy order.

2. Naming the specific allergen rather than writing only “allergy”.

3. Verbally alerting the kitchen or designated responsible person.

4. Receiving confirmation that the request has been understood.

5. Checking whether the kitchen can control ingredients and cross-contact.

6. Returning the verified answer to the customer.

7. Keeping the allergy identifier attached to the order until service.

Avoid relying entirely on verbal communication during busy periods. Spoken information should be supported by a visible record in the point-of-sale system, kitchen ticket or approved manual process.

A common operational failure occurs when the front-of-house employee checks the main recipe but does not communicate the allergy to the person plating the meal. The final garnish, sauce, bread or dessert accompaniment can then introduce an allergen that was not present in the main component.

Serving Safely and Avoiding Mix-Ups

Key takeaway: Keep the verified allergy order identifiable from preparation through final delivery.

Once the kitchen accepts the order, the business must prevent it from being confused with standard meals.

Practical controls include:

• Using a clearly identified allergy ticket or order marker.

• Assigning one responsible person to check the completed meal.

• Keeping the dish separate from unverified orders during collection.

• Avoiding last-minute ingredient substitutions.

• Confirming table and seat numbers before leaving the service point.

• Having the server state that the dish is the specially checked order.

• Preventing another server from adding unverified garnishes or condiments.

Staff should not claim that a meal is “100% allergen-free” unless the business has a validated basis for making that statement. A more accurate explanation is that the dish has been checked against the business’s current information and prepared using the controls the business can provide.

Where the kitchen cannot adequately control cross-contact—for example, because the same fryer, grill or preparation surface must be used—the customer should be told clearly. Staff should not present ingredient absence and cross-contact control as the same thing.

Example Front-of-House Allergen Script

Key takeaway: Use a consistent script that makes verification—not reassurance—the centre of the conversation.

The following example can be adapted to the business’s documented procedure.

Customer: “I have a sesame allergy. Is the chicken dish safe for me?”

Staff member: “Thank you for telling me. I’ll record the sesame allergy and check the dish, sauces, garnishes and preparation method with the kitchen.”

Staff member to kitchen: “Table 12 has declared a sesame allergy and is asking about the chicken dish. Please check the current recipe, supplier information and cross-contact risk.”

Kitchen or responsible person: “The chicken marinade contains sesame oil, so that dish is not suitable. The baked fish does not contain sesame, but it is prepared near sesame products. We can use a cleaned workstation and separate utensils, although we cannot describe the kitchen as completely sesame-free.”

Staff member to customer: “The chicken contains sesame oil, so we cannot recommend it. The kitchen has checked the baked fish and can prepare it using a cleaned area and separate utensils, but sesame is handled elsewhere in the kitchen. Would you like to consider that option, or would you prefer another dish?”

The customer can then make an informed decision based on accurate information rather than an unsupported promise.

What Staff Should Never Say

Avoid phrases such as:

• “It should be fine.”

• “There is only a little.”

• “The chef thinks it is safe.”

• “We have never had a problem before.”

• “Just remove the sauce.”

• “It probably does not contain that.”

• “We cannot guarantee anything, so it is entirely your responsibility.”

The memorable rule is simple: never guess; always verify.

Country variations: Article 44 of Regulation (EU) No 1169/2011 makes allergen information mandatory for non-prepacked food, but Member States may specify how that information must be communicated and presented. Businesses operating in more than one EU country should check the relevant national requirements, inspection practices and training expectations.

Front-of-House Allergen Request Checklist

Key takeaway: Staff should complete every control before confirming or serving an allergy order.

Before the order proceeds, confirm that:

• The customer’s allergen has been repeated back correctly.

• The request has been entered clearly in the ordering system.

• The kitchen or responsible person has been alerted.

• The current allergen matrix has been checked.

• The recipe and current supplier information agree with the matrix.

• Sauces, garnishes, sides and drinks have been included.

• Shared equipment and preparation areas have been considered.

• The kitchen has confirmed whether the order can be accepted.

• The verified answer has been communicated clearly to the customer.

• The completed meal will remain identifiable until service.

• Any uncertainty has been disclosed rather than guessed.

Managers should test this procedure through observation, scenario exercises and periodic review. Training records, matrix updates, supplier changes and corrective actions should be documented as part of the business’s wider food allergen awareness programme.

Train Front-of-House Staff to Respond Consistently

Key takeaway: Training should give staff a repeatable procedure they can apply during real service conditions.

A written policy is not enough when employees do not know how to use it during a busy shift. Front-of-house training should cover the regulated allergens, customer communication, order recording, use of the allergen matrix, escalation routes, cross-contact awareness and emergency procedures.
