Sarah had visited the restaurant three times before. She always asked about allergens. Each time, staff reassured her they’d checked with the kitchen and she’d be fine.

On the fourth visit, something went wrong. Nobody had told the new kitchen porter about her allergy. As a result, the dish arrived cross-contaminated.

What followed was a medical emergency. Her family was distressed. The business owner sat in their car at midnight, wondering how it had come to this.

Why This Keeps Happening

This isn’t a horror story invented to frighten you. Incidents like this happen in UK food businesses every year. In almost every case, the root cause is the same.

The allergen information existed somewhere. But the system for communicating it broke down. So a customer paid the price.

What UK Law Requires

UK food law requires all food businesses to give customers accurate allergen information. There are 14 major allergens you must declare whenever they appear as an ingredient. You must communicate this accurately, every time, regardless of who’s working that shift.

The 14 allergens are:

  • Celery
  • Cereals containing gluten (wheat, rye, barley, oats)
  • Crustaceans (prawns, crabs, lobster)
  • Eggs
  • Fish
  • Lupin
  • Milk
  • Molluscs (clams, mussels, oysters, squid)
  • Mustard
  • Peanuts
  • Sesame
  • Soybeans
  • Sulphur dioxide and sulphites (found in wine, dried fruits, and many preserved products)
  • Tree nuts (almonds, hazelnuts, walnuts, cashews, pecans, pistachios, and more)

This applies whether you run a restaurant, a café, a catering operation, a food truck, or a dark kitchen. It also covers food sold for delivery, not just in-person service. You don’t get to pick and choose where the rules apply.

Where Most Businesses Get It Wrong

The allergen information usually exists. It’s sitting in a folder, or on a spreadsheet the head chef built two years ago. But it doesn’t move.

It doesn’t travel with the dish from prep to plate. It doesn’t update when a supplier changes an ingredient. So when a new team member starts, it doesn’t reach them either.

Manual allergen management is a chain with too many weak links. Any one of them can break. Worse still, when one does break, the consequences can be severe.

Staff Turnover Makes It Worse

Hospitality has one of the highest staff turnover rates of any UK industry. Every new person who joins your team needs to understand your allergen controls from scratch. That’s a real and constant risk.

If your system relies on institutional knowledge rather than a documented process, you’re always one new hire away from a serious incident. In practice, many businesses don’t realise this until something goes wrong. By then, it’s too late.

Know the 14 Allergens Cold

You need to track each allergen through every dish on your menu, including daily specials. Every ingredient in every recipe needs checking. Every supplier change needs to trigger a review.

For example, cereals containing gluten covers wheat, rye, barley, oats, and products made from them. Tree nuts is a broad category covering almonds, hazelnuts, walnuts, cashews, pecans, and pistachios. Sulphur dioxide and sulphites appear in wine, dried fruits, and many preserved products at concentrations that require declaring.

This is genuinely complex. It’s not a criticism. It’s simply the reality of running a food business under UK allergen law.

How a Digital System Helps

Food Safety Pro gives you one place to store, manage, and share allergen information across your whole operation. When a recipe changes or a supplier sends a new product, you update it once. After that, the change flows through automatically.

Your front-of-house staff can check accurate allergen information in real time. Instead of relying on a laminated sheet that hasn’t been updated since last spring, they’ve got the current facts at their fingertips. So every customer enquiry becomes something you can handle with confidence.

On the other hand, if an EHO or Trading Standards officer asks to see your allergen records, you’ll have a clear audit trail ready to go. There’s no scrambling, no guessing, no gaps. That’s the difference a proper system makes.
