Allergen Labeling in Practice: 5 Examples for Different Business Types
Introduction
The legal framework for allergen labeling is clear — but what does implementation actually look like in day-to-day food service operations? The optimal approach varies significantly by business type: a full-service restaurant solves the problem differently from a food truck or an online delivery service. This guide presents five concrete real-world examples with labeling solutions, practical tips, and the specific challenges of each business type. For the legal foundations and a step-by-step implementation guide, see Allergen Labeling Implementation and Allergens on the Menu.Example 1 — Classic Restaurant
Business type: Full-service restaurant with 80 or more dishes, printed menu, table service.
Recommended method: The most established and legally robust system for classic restaurants is a letter-based footnote system, using letters A through N corresponding to the 14 EU mandatory allergens. Each dish in the menu receives a bracketed suffix listing the relevant letters; a complete legend appears at the foot of each menu page or on a dedicated legend page.
Concrete menu example:
| Dish | Price | Allergens |
|---|---|---|
| Veal schnitzel, lemon butter | £24.50 | (A, C, G) |
| Salmon, wilted spinach, mustard-dill sauce | £22.00 | (D, J) |
| Tiramisu | £8.50 | (C, G, ³) |
Legend:
A = Cereals containing gluten | C = Eggs | D = Fish | G = Milk | J = Mustard
³ = with preservative (mascarpone product)
Practical tips:
- Additives (preservatives, flavour enhancers, colorants) are indicated with separate numbers, keeping letters for allergens and numbers for additives clearly distinct
- The legend must appear on every page or in a consistently accessible section of the menu
- Update the printed version immediately when recipes change — outdated printed menus are one of the most common findings in food safety inspections
- Recommend maintaining a digital parallel record of allergen data to enable fast updates
Example 2 — Bistro / Café
Business type: 20 to 30 items, chalkboard menu or counter display, counter service, daily cake and baked goods selection.
Recommended method: Combination of a symbol or letter system on the chalkboard and a full allergen folder at the counter. The chalkboard itself offers limited space for detailed information — small allergen icons or letters directly after the dish name work well. The complete allergen documentation is maintained in an A4 folder at the counter, accessible to guests on request and available to staff at all times.
Special requirements for baked goods:
Cakes, pastries, and baked goods must be individually and visibly labeled at the point of display — not only in the background folder. Small placards or tent cards directly beside each item in the display case, clearly listing the key allergens (for example: „Contains: gluten, eggs, milk, hazelnuts“), are the most guest-friendly solution.
Practical tip: Daily specials written on the chalkboard require immediate allergen annotation — they carry the same declaration obligation as printed menu items. A simple system using three or four recurring symbols (a wheat ear for gluten, a milk drop, an egg) makes daily maintenance significantly faster.
Example 3 — Catering
Business type: Variable menus, buffet service, events of 50 to 500 guests, pre-ordered dishes for seated dining.
Recommended method: A two-tier system combining advance communication and on-site labeling.
In advance (no later than order confirmation): The event organizer receives a complete allergen table for the booked menu by email or as an attachment to the booking confirmation. This also serves as the basis for handling pre-registered dietary requirements when guests notify the organizer of allergies in advance.
On-site at the buffet: Every single dish at the buffet receives a dedicated table stand showing the dish name and the allergens it contains. A consistent, clearly legible format works best — for example DIN A6 cards with the dish name at the top and allergen icons or letters at the bottom. Staff must be trained and available to answer allergen questions from guests.
Important detail: Dishes at buffets are frequently combined by guests, and sauces are sometimes served separately. Label sauces and dressings individually if they contain distinct allergens not present in the main dish. The complete written allergen documentation must accompany the catering delivery — this is an explicit requirement under EU FIC for distance selling/catering contexts.
Example 4 — Food Truck
Business type: Five to ten dishes, small menu board, fast service, changing locations.
Recommended method: Laminated A4 notice at the order window with a complete allergen table for all dishes — clearly visible, weatherproof, and updated at every menu change. Trained staff should be available for verbal allergen enquiries. A QR code at the order window linking directly to a mobile-optimized page with an allergen filter is a space-efficient modern addition.
Special considerations:
- At every location change, the allergen documentation must be physically transported and immediately available
- The A4 notice should be laminated in a sleeve that accepts replaceable inserts, enabling fast updates without reprinting the entire laminated sheet
- If no QR code is in use, the A4 notice must comprehensively cover all 14 allergens for every dish offered — not only the most common ones
Practical tip: For a very short menu of only three or four dishes, a compact two-column table on a single laminated A4 sheet can cover all required information efficiently: dish names on the left, allergen letters on the right, legend at the bottom.
Example 5 — Delivery Service
Business type: Online ordering via own website or third-party platform, delivery without in-person consultation.
Recommended method: EU FIC creates a two-part obligation for delivery services: allergen information must be available before the order is completed in the online presentation, and it must accompany the delivery in written form.
Online implementation:
- For every dish on the ordering page, include an allergen display showing the relevant allergens using written names or standardized icons
- Allergen filters enabling customers to search for dishes free from specific allergens are best practice and significantly improve the guest experience
- A link to a PDF buried in the terms and conditions is not sufficient — the information must be actively accessible before checkout
At delivery:
- Include a small insert (minimum A6 size) with an allergen table for all dishes included in that specific delivery
- Alternatively: a QR code on the delivery slip or packaging that links directly to the current allergen documentation

Frequently Asked Questions
What does correct allergen labeling on a menu look like?
Correct allergen labeling on a menu in food service practice typically uses a letter or number footnote system. After each dish name, a bracketed suffix lists the letters corresponding to allergens present in that dish — for example, „Veal schnitzel (A, C, G)“. At the foot of the menu page or on a separate legend section, each letter is assigned to one of the 14 EU mandatory allergens: „A = Cereals containing gluten, C = Eggs, G = Milk,“ and so on for all 14.
The allergen letters or numbers in the legend must be **visually emphasized** — through bold type, a contrasting color, or underlining — making them immediately identifiable for guests with allergies who are specifically looking for them. Food additives (preservatives labeled „with preservative,“ flavour enhancers labeled „with flavour enhancer“) are indicated using separate number codes, maintaining a clear distinction between letters for allergens and numbers for additives. This dual system is widely used, recognized by food safety inspectors, and scales well to large menus. For complete implementation guidance, see Allergens on the Menu.How do you label allergens on a food truck?
Food trucks are subject to exactly the same legal allergen labeling obligations as a full-service restaurant — there is no size exception or exemption for fast-paced or outdoor operations. The most practical and legally sound solution is a laminated A4 notice displayed prominently at or immediately beside the order window, listing the allergens present in each dish in a clear table format. The document must be carried to every location and updated immediately whenever the menu changes.
In most EU member states (including Germany), oral allergen communication is permissible as a supplement to written information, provided a clearly visible notice informs guests that allergen information is available verbally and a complete written record is maintained in the background. A QR code displayed at the order window, linking to a mobile-optimized allergen page or digital menu with allergen filters, is a space-efficient and modern alternative that eliminates the need for bulky physical documentation at the window. For a very short menu of three or four dishes, a compact two-column table on one laminated A4 sheet — dishes on the left, allergen letters on the right, legend at the bottom — provides complete coverage in minimal space.
How does allergen labeling work for catering?
Catering operations face distinct challenges because menus vary from event to event and buffet service — where many dishes are presented simultaneously — is the standard format. At a buffet, every individual dish must be separately labeled — the allergen information for one item does not carry over to adjacent items, even if they appear visually similar. Individual table stands in a consistent format (DIN A6 works well) with the dish name and allergen indicators are the most practical solution: they are quick to place, easy to replace between events, and readable by guests moving along a buffet line.
Before the event, the organizer should receive a complete allergen overview for the booked menu — ideally attached to the booking confirmation. This enables the organizer to share allergen information with guests who have declared dietary requirements. For delivery-based catering, the complete written allergen documentation must accompany the delivery — this is explicitly required under EU FIC for distance selling scenarios. Catering businesses benefit particularly from standardized templates that can be adapted for each event in minutes. For free template resources, see free templates.What rules apply to delivery services?
Delivery services fall under the distance selling provisions of EU FIC Regulation 1169/2011, which create a two-part obligation. First, allergen information must be visible and accessible to the customer before the order is completed — in the online shop, app, or order form. Information that appears only after clicking „confirm order“ does not satisfy the requirement. Second, allergen information must accompany the delivery in written form, either on the packaging or as a printed insert.
In the online ordering interface, each dish must have an accessible allergen display — allergen names written out or standardized icons both qualify. Allergen filter functionality that allows customers to view only dishes free from their specific allergens is considered best practice and strongly recommended for any serious delivery operation. At the point of delivery, an insert of at least A6 size covering all allergens in the delivered order is the minimum standard. A QR code on the insert linking to the live allergen documentation is a valid digital alternative. Platform responsibility is frequently misunderstood: while Deliveroo, Uber Eats, and similar platforms provide fields for allergen information, the legal responsibility for the accuracy and completeness of that information rests entirely with the food business operator.
