Allergen Management for Restaurants — Stay Compliant, Keep Guests Safe

Every year, people in Europe are hospitalised because of undeclared allergens in restaurant food. Some die. EU Regulation 1169/2011, amended by subsequent national laws, requires restaurants to declare 14 major allergens for every dish they serve. Not just on packaged food. In restaurants, at the table, on every menu.

The fine for non-compliance in Germany can reach EUR 50,000. The reputational damage from a serious allergic reaction incident is worse. This is not a bureaucratic nuisance. It is a genuine guest safety issue, and the operational side of managing it is where most restaurants fall short.

The 14 allergens you must declare

EU law requires labelling of: cereals containing gluten (wheat, rye, barley, oats), crustaceans, eggs, fish, peanuts, soybeans, milk, nuts (almonds, hazelnuts, walnuts, cashews, pecans, Brazil nuts, pistachios, macadamia nuts), celery, mustard, sesame, sulphur dioxide and sulphites (above 10mg/kg), lupin, and molluscs.

"Declare" means the information must be available to guests before they order. Written menu, verbal staff explanation with documented backup, digital display. All are legally valid in most EU jurisdictions, but you must have a documented process and be able to produce that information consistently.

Where restaurants go wrong

The most common failures are: allergen info written on a paper sheet kept in the kitchen that nobody reads, inconsistent verbal staff communication ("I think it's fine but ask the chef"), and menu updates that don't carry through to allergen documentation. When you change a recipe or substitute an ingredient, every dish affected needs its allergen information updated immediately.

A restaurant relying on a spreadsheet to track allergens across 80+ dishes, across multiple recipe iterations, will eventually make a mistake. The mistake might be minor. Or it might send a guest to the emergency room.

How Plattr handles allergen tagging

When you build your menu in Plattr, every dish has allergen fields. You check the boxes for each of the 14 allergens present. Those selections then appear automatically on your digital menu, your Plattr Guide listing, and any QR table ordering interface you use.

Update a recipe and need to add a new allergen? Change it once in your dashboard and it propagates everywhere. No reprinting paper menus. No manually updating a website. No briefing staff to tell guests something different from what's written.

The AI Menu Recognizer can scan your existing paper menu and pre-fill your Plattr menu database. But allergen tagging is one step you should do manually — AI can parse dish names and descriptions, but it cannot reliably identify hidden allergens from a text description alone. After the AI import, go through each dish and tag allergens yourself.

Staff training and documentation

Digital allergen management reduces the risk of errors but does not eliminate the need for staff training. Guests with serious allergies will often ask a server directly rather than consulting a menu. Your team needs to know: where to find allergen information, what to say when they don't know (never "it should be fine"), and when to escalate to the kitchen.

Document your training. A signed acknowledgement that each staff member completed allergen training, dated and filed, protects you if an incident leads to a regulatory inspection. This is standard practice in the UK and increasingly expected in Germany and Austria.

Cross-contamination: the harder problem

Declaring allergens on a menu is the easier part. Managing cross-contamination in a busy kitchen is harder. If you fry both gluten-free dishes and breaded items in the same oil, the gluten-free dish is not actually safe for coeliac guests, regardless of what the menu says. Your allergen declarations should include preparation notes where relevant.

Some restaurants add a blanket disclaimer: "Our kitchen handles all 14 major allergens and we cannot guarantee a fully allergen-free environment." This is honest, legally appropriate, and helps manage guest expectations. It does not excuse failing to declare known allergens, but it does address the cross-contamination reality.

Digital menus and legal compliance

A digital menu counts as written allergen information under EU law, provided it is accessible to guests before they order. A QR code at the table that links to your Plattr menu with allergen tags visible satisfies the written disclosure requirement in most EU member states. Check your specific national implementation of the regulation, as some countries have additional requirements.

The advantage of digital allergen display is real-time accuracy. When you update allergen information in your Plattr dashboard, it is live immediately. No lag, no version mismatch between paper and digital, no risk of a guest reading an outdated allergen list.

Making it part of your menu management workflow

Integrate allergen review into your menu update process. Every time you add a dish or change a recipe: update the dish in Plattr, update allergen tags, and confirm the change appears correctly on your digital menu. Take a screenshot and save it. This three-step process, done consistently, builds a defensible compliance record.

Seasonal menus are a particular risk. Restaurants that change their menu four times a year have four opportunities to create allergen gaps. Plan your menu changes, allocate time for allergen review, and do not publish a new menu until allergen information is complete.

Starting fresh with a complete allergen record

If your current allergen management is informal — a spreadsheet, a binder, verbal communication — the fastest path to compliance is moving your entire menu to a digital system with built-in allergen fields. Set up your Plattr account, import your menu (or use the AI scanner for a first pass), and then spend one afternoon tagging allergens correctly across all your dishes. It's a one-time investment that protects your guests and your business every day after.
