Allergen Matrix Template --- Track Every Allergen Across Every Dish

An allergen matrix is a grid that maps your menu items against the 14 UK-regulated allergens. On one axis you list every dish, product, and component you serve; on the other, each of the 14 allergens. At each intersection, you indicate whether that allergen is present, absent, or whether there's a risk of cross-contamination.

Think of it as a single source of truth for allergen information. When a customer says "I'm allergic to milk --- what can I eat?", your staff don't need to run to the kitchen, find the chef, and guess. They check the matrix and give an accurate answer in seconds. It's the difference between a confident, safe dining experience and a potential anaphylactic incident.

The matrix is not just a customer-facing tool. It's also the foundation for your Natasha's Law compliance (PPDS labelling), your supplier verification process, and your staff training programme. Get the matrix right, and everything else flows from it.

UK food law mandates that all 14 of these allergens must be declared when present in food you sell. Your allergen matrix must cover every one of them, even if your menu doesn't currently contain them. Suppliers change ingredients, and recipes evolve --- the matrix must be comprehensive.

The "hiding spots" are critical. An allergen can appear in your kitchen through compound ingredients --- items you buy that themselves contain allergens. A stock cube might contain celery, a bread roll might contain sesame, a pre-made sauce might contain mustard. You need to trace allergens through every component, not just the obvious ones.

Building an allergen matrix is methodical work, but it only needs to be done properly once. Here's the step-by-step process:

Step 1: List every dish and component. Don't just list main menu items --- include sides, sauces, garnishes, dressings, and any optional add-ons. A burger isn't just "burger" --- it's the bun, the patty, the cheese, the lettuce, the sauce, and the pickle. Each component may contain different allergens.

Step 2: Gather supplier spec sheets. For every ingredient, obtain the full ingredient specification from your supplier. Don't rely on what's printed on the outer packaging --- get the formal spec sheet. This is also required for your SFBB records.

Step 3: Map allergens to each dish. Work across each row (dish) and mark each column (allergen) with one of three indicators: ✓ (present), ✗ (absent), or ⚠ (cross-contamination risk). Be conservative --- if there's any doubt, flag the risk.

Step 4: Validate and date-stamp. Have a second person review the matrix. Date-stamp it so you know when it was last updated. This is important for EHO inspections --- they want to see that the matrix is a living document, not something you printed once in 2019.

Step 5: Make it accessible. The matrix needs to be where staff can find it instantly --- not buried in a folder in the office. Consider a laminated copy on the kitchen wall, a digital version on a tablet, or a version integrated into your POS system.

You have several options for your allergen matrix. The right choice depends on the size of your menu, how frequently it changes, and whether you need to share allergen data across multiple locations:

Excel spreadsheet. The most flexible free option. You can sort, filter, and update easily. Colour-code cells to show presence, absence, and cross-contamination. Print individual pages for staff stations. The downside: Excel files get copied, emailed, and versioned. By the time you've updated one cell, three other copies are out of date and floating around your kitchen.

Printable PDF. Clean, professional, and easy to laminate for kitchen walls. Perfect for businesses with static menus. The limitation is obvious: every menu change means printing and laminating again. If you're changing specials weekly, a PDF matrix becomes a chore.

Which format is right for you? If your menu changes less than once a month and you have a single site, a well-maintained Excel sheet or PDF works. If you run multiple locations, change your menu frequently, or want to integrate allergen data with your PPDS labelling, a digital solution saves hours of admin and eliminates version-control errors.

Natasha's Law came into force on 1 October 2021 and requires all Prepacked for Direct Sale (PPDS) foods to carry a full ingredient list with allergens emphasised. If you make food on your premises and package it before a customer orders it --- think pre-wrapped sandwiches, salads, cakes, or pastries in a display cabinet --- you need PPDS-compliant labelling.

Your allergen matrix is the engine that drives your PPDS labels. Each PPDS item must list every ingredient and bold the 14 allergens. Without an accurate matrix, you can't produce accurate labels. With an accurate matrix, label production becomes a mechanical process --- pull the allergen data, format it, and print.

The matrix-to-label workflow: Dish → allergen matrix → PPDS label. If this chain breaks anywhere, you're non-compliant. A customer with an allergy could eat something that isn't properly labelled. The consequences range from a hygiene rating downgrade to criminal prosecution under the Food Safety Act.

An allergen matrix is never "done." Suppliers change formulations, you tweak recipes, seasonal menus rotate in and out. Every change requires an update to the matrix. The single biggest compliance risk for most food businesses isn't creating the matrix --- it's keeping it current.

Supplier changes. When a supplier notifies you of a recipe change, check it against the matrix immediately. A new ingredient in a sauce you buy could introduce an allergen into multiple dishes. Build a habit: every delivery, every spec sheet update, triggers a matrix review.

Recipe changes. When you add a dish, change a recipe, or substitute an ingredient, update the matrix before the new version goes to customers. Don't do the "we'll update it tomorrow" thing --- tomorrow is when a customer with a nut allergy orders the new dish.

Scheduled reviews. Even if nothing has changed, schedule a full matrix review at least every four weeks. This aligns with your SFBB 4-weekly review cycle and catches any changes that slipped through. Document the review with a date and signature.

Staff communication. When the matrix changes, every front-of-house team member needs to know. The matrix on the wall means nothing if your servers are still working from memory of the old version. Briefing all staff on allergen updates should be part of your pre-service routine.
