Communicating Allergens to Customers: Verbal, Written & Digital

Communicating Allergens to Customers: Verbal, Written & Digital

The way you communicate allergen information to customers is as important as the accuracy of the information itself. The best allergen matrix in the world is useless if a server cannot explain it, a customer cannot find it, or the information is presented in a format that is confusing or inaccessible. Communication failures are a factor in the majority of allergen incidents. The customer asked but was given incorrect information. The customer did not know to ask. The staff member was unsure and guessed. The menu was unclear. This article covers how to communicate allergens effectively across every channel your business uses.

Key takeaways

Staff must follow a consistent protocol when a customer discloses an allergy: acknowledge, ask, check, communicate
Written allergen information should be visible at the point of ordering, not just available on request
Online allergen data must appear before the customer confirms their order, not buried in a separate page
Train staff to handle difficult conversations, including saying no when you cannot guarantee safety
Never guess, never dismiss, and never promise zero risk unless you can genuinely guarantee it

Verbal Communication: Scripts and Protocols

When a customer discloses an allergy verbally, your staff's response must follow a consistent protocol. Train staff to acknowledge the allergy seriously (never dismiss or minimise), ask specifically which allergen or allergens are involved, check the allergen matrix or recipe information (never rely on memory), communicate the finding clearly ("This dish contains milk in the sauce. I can check with the kitchen about alternatives"), and escalate to a manager or chef if they are unsure about any detail. Provide staff with scripts or talking points for common scenarios. "Let me check our allergen information for you" is always better than "I think it should be fine." "I'm not sure, so let me ask the chef" is always better than guessing. Train staff that saying "I don't know, let me find out" is a strength, not a weakness. The communication chain must also extend to the kitchen. When an allergen order is identified, there must be a clear, consistent method for communicating it to the person preparing the food: a verbal callout, a marked ticket, or a digital flag.

Written Communication: Menus, Signage, and Information Packs

Written allergen information should be available without the customer having to ask. At minimum, display a clear sign directing customers to ask about allergens. Better still, include allergen codes on your menu. Best practice is a combination: allergen codes on the menu for quick reference, a detailed allergen matrix available on request, and trained staff to discuss specifics. The written material must be clear, current, and accessible. Use plain language. "Contains wheat (gluten)" is clearer than allergen code "3" for most customers, though codes save space on menus. For businesses serving customers with visual impairments, consider large-print allergen information on request. For businesses serving non-English-speaking customers, consider pictorial allergen symbols that do not rely on text. Your signage should be visible at the point where customers make ordering decisions. A sign by the till is too late if customers decided what to order while looking at a menu board across the room.

Digital Communication: Websites, Apps, and Social Media

If customers can order online, your website or app must display allergen information before the order is confirmed. This is a legal requirement under distance selling provisions. Allergen data should appear on individual product or dish pages, not buried in a separate PDF or FAQ page that customers may never find. For social media, avoid posting food content without allergen context. A photo of your "new special" on Instagram that generates orders but provides no allergen information creates risk. Include allergen summaries in posts about specific dishes, or direct followers to your full allergen information. QR code menus should link to mobile-friendly pages with clear allergen data. Test the customer journey on a phone: can a customer find the allergen information for a specific dish within two taps? If not, simplify the interface.

Handling Difficult Allergen Conversations

Some allergen conversations are straightforward. Others are not. A customer with multiple severe allergies may need extensive discussion about what is safe to eat. A customer may push back when told a dish they want contains their allergen ("But I have had it before and it was fine"). A customer may ask if you can "just leave out" an ingredient without understanding that cross-contact is still a risk. Train staff to handle these situations with patience and clarity. Never override a customer's allergy disclosure, even if they seem uncertain. Never promise that a dish is "completely free" of an allergen unless you can genuinely guarantee zero cross-contact. If you cannot safely serve a customer with a particular allergy, say so honestly. "I am sorry, but given the allergens in our kitchen, I cannot guarantee this dish is safe for you" is a responsible answer. Turning away a sale is always better than causing a reaction. Document any significant allergen conversations (particularly where you advised a customer against ordering a dish) in case the interaction is later questioned.

What to do next

Create allergen conversation scripts for staff

Write scripts covering common allergen scenarios: customer discloses an allergy, customer asks about a specific dish, customer has multiple allergies, and customer pushes back on advice. Practice during training.

Review your online allergen information journey

Order from your own website or app as a customer with an allergy. Check that allergen information appears before you confirm the order and that it is accurate and easy to find.

Install visible allergen signage at the point of ordering

Place a clear sign at the counter, menu board, or entrance directing customers to ask about allergens. Ensure it is visible before they make their ordering decision.

Common mistakes to avoid

Mistake
Staff guessing about allergens instead of checking
Instead
Train staff that checking is always the correct response. Provide quick-access allergen matrices at every service point so checking takes seconds, not minutes.
Mistake
Burying allergen information on a separate website page
Instead
Allergen data must be visible at the point of choice. On a website, this means on the dish or product page, not in a separate PDF or FAQ section.

Frequently asked questions

What should I do if a customer says they are allergic but then orders a dish containing that allergen?

Politely confirm their allergy and advise that the dish they have ordered contains the allergen. If they choose to proceed after being clearly informed, document the conversation. You have met your obligation to provide the information.

Should I ask every customer about allergies?

This is not a legal requirement, but it is a growing best practice, particularly in table-service restaurants. A simple "Does anyone at the table have any food allergies?" at the start of service demonstrates proactive care.

How do I handle allergen information for phone orders?

Train staff taking phone orders to ask about allergies, check the allergen matrix during the call, and include a written allergen sheet with the order when it is collected or delivered. Record the allergen conversation on the order notes.
