Allergen Awareness Week is the perfect opportunity to step back and critically examine your allergen management procedures. In the UK, allergen-related incidents remain a leading cause of food safety enforcement actions, and tragedies linked to poor allergen controls continue to make headlines. Whether you are a restaurant, cafe, takeaway, or catering company, a thorough allergen audit is not optional — it is essential to protecting your customers and your business. This guide walks you through a structured audit process you can implement immediately.
The Legal Framework You Must Understand
UK allergen law is built on several pillars. The Food Information Regulations 2014 require food businesses to provide accurate allergen information for all 14 major allergens, whether food is pre-packed, sold loose, or provided as pre-packed for direct sale (PPDS). Natasha's Law, which came into force in October 2021, specifically requires that PPDS food carries a full ingredients list with allergens emphasised. Beyond labelling, Regulation (EC) No 852/2004 requires you to have systems in place to prevent cross-contamination. Your audit must verify compliance with all of these requirements.
Step 1: Review Supplier Information
Your allergen management chain begins with your suppliers. Audit every ingredient you receive by checking that you hold current allergen specifications for each product. Contact suppliers directly to confirm that their information is up to date, as recipes and manufacturing processes change frequently. Pay particular attention to products that carry "may contain" warnings — these indicate a genuine risk of cross-contamination during manufacture. Document your supplier checks and keep records filed where they can be accessed quickly during an inspection.
Step 2: Update Your Allergen Matrix
An allergen matrix is a grid that maps every dish on your menu against the 14 major allergens. Check each dish individually against current supplier specifications. If you have changed any ingredients, added new dishes, or altered recipes since your last review, the matrix must be updated. Display the matrix where kitchen and front-of-house staff can reference it easily. Our allergen management checklist provides a template to help you build or refresh your matrix.
Step 3: Assess Cross-Contamination Controls
Walk through your kitchen and observe how allergen-free meals are actually prepared in practice. Look for:
- Dedicated utensils and preparation surfaces for allergen-free cooking
- Separate storage for allergen-free ingredients, away from potential sources of contamination
- Cleaning procedures between preparing allergen-containing and allergen-free dishes
- Separate fryers for gluten-free items
- Proper hand hygiene between tasks involving different allergens

Step 4: Evaluate Front-of-House Communication
Excellent kitchen controls mean nothing if front-of-house staff cannot communicate allergen information accurately to customers. Test your team by asking them to explain the allergen content of several dishes without referring to the matrix. Check that your menus include a clear allergen statement directing customers to ask a team member. Verify that there is a reliable system for passing allergen requests from the customer to the kitchen — verbal systems are prone to error, so consider written allergen order tickets.
Step 5: Test Team Knowledge
Conduct short, informal quizzes with your team. Can they name all 14 major allergens? Do they know what to do if a customer reports an allergic reaction? Can they identify which dishes on your menu contain specific allergens? If gaps emerge, schedule refresher training immediately. Our allergens course is designed specifically for hospitality teams and can be completed in a single session.
Step 6: Review Documentation and Record-Keeping
Good documentation is your evidence of due diligence. Check that you have written records of supplier allergen specifications, your allergen matrix (dated and signed), staff training records showing allergen training completion, cleaning schedules demonstrating allergen controls, and any allergen incidents and the corrective actions taken. If an Environmental Health Officer visits, or if a customer suffers a reaction, these records demonstrate that you took all reasonable precautions.
Getting Professional Support
If your audit reveals significant gaps, or if you lack the confidence to assess your own procedures objectively, consider bringing in expert help. Our food safety consulting service includes comprehensive allergen audits conducted by experienced consultants who understand exactly what enforcement officers look for. For urgent issues, our emergency support team can respond quickly.
Frequently Asked Questions
How often should I audit my allergen procedures?
At minimum, conduct a full allergen audit every six months. Additionally, review procedures whenever you change your menu, switch suppliers, or introduce new ingredients. An annual third-party audit provides the most robust assurance.
What are the penalties for failing to comply with Natasha's Law?
Non-compliance with allergen legislation can result in improvement notices, fines, prosecution, and in the most serious cases, prison sentences. Beyond legal penalties, an allergen incident can cause devastating harm to a customer's health and irreparable damage to your business reputation.
Can I use "may contain" warnings on my menu?
"May contain" warnings should only be used when there is a genuine, unavoidable risk of cross-contamination that you cannot eliminate through your controls. They must never be used as a blanket disclaimer to avoid managing allergens properly. The FSA advises that these warnings should be based on a thorough risk assessment.
