For anyone working in the food industry, managing allergens has always been a critical part of food safety. However, with increasing awareness of food allergies and new legislation placing greater emphasis on protecting people with allergies, there has never been a more important time to review your allergen control procedures.
Whether you run a restaurant, café, school kitchen, care home, hospital, catering business or food manufacturing operation, robust allergen management helps protect customers, supports legal compliance and reduces the risk of costly mistakes.
Why allergen management is becoming more important?
Food allergies affect millions of people across the UK, with thousands experiencing severe allergic reactions every year. Even tiny traces of an allergen can trigger a potentially life-threatening reaction known as anaphylaxis.
In response, legislation and industry guidance continue to evolve, placing greater responsibility on food businesses to provide accurate allergen information and demonstrate effective allergen controls.
From September 2026, schools in England will also be required to strengthen allergy management through new measures introduced under Benedict's Law. While these changes are aimed at education settings, they highlight the growing expectation that all organisations serving food should have comprehensive allergen management systems in place.
Customers are also more informed than ever before. They expect staff to understand allergens, answer questions confidently and prepare food safely.
What is cross-contamination?
Cross-contamination occurs when an allergen is unintentionally transferred from one food, surface or piece of equipment to another.
Unlike bacteria, allergens cannot be destroyed by cooking. Once they have been transferred, they remain present until they are effectively removed through thorough cleaning and good food handling practices.
Common causes of allergen cross-contamination include:
- Using the same chopping boards or knives for allergen-containing and allergen-free foods.
- Preparing different foods on the same work surface without cleaning between tasks.
- Shared utensils such as tongs, spoons and spatulas.
- Reusing gloves after handling allergenic ingredients.
- Incorrect food storage allowing ingredients to come into contact.
- Poor labelling of prepared foods or ingredients.
- Staff not washing their hands thoroughly between tasks.
Even a small amount of contamination can have serious consequences.
Building an effective allergen management system
Effective allergen management is about much more than displaying allergen information. It requires procedures throughout every stage of food preparation.
Key areas include:
| Staff training | Every member of staff who prepares, handles or serves food should receive allergen awareness training that covers the 14 regulated allergens, how cross-contamination can occur, safe food handling and cleaning procedures, responding confidently to customer allergen enquiries, and the appropriate actions to take in an emergency. Regular refresher training helps reinforce best practices, maintain consistency across the team and ensure ongoing compliance with food safety standards. |

Colour-coded allergen equipment
|
Many catering businesses use dedicated purple equipment to help prevent allergen cross-contamination during food preparation. This can include purple chopping boards, knives, utensils, storage containers, labels, tongs and other serving equipment, all clearly identified for allergen-safe use. By using colour-coded tools exclusively for preparing allergen-free meals, staff can quickly identify the correct equipment, reducing the risk of mistakes and helping to maintain a safe food preparation environment. |
|
Clear food labelling |
Clear and accurate food labelling plays a vital role in preventing mistakes during food storage, preparation and service. Using reusable allergen labels, colour-coded stickers and clearly marked food containers helps staff identify ingredients quickly, reducing the risk of confusion, cross-contamination and accidental exposure to allergens. |
|
Effective cleaning |
Effective cleaning is essential for removing allergen residues from equipment, utensils and food preparation surfaces. Businesses should have documented cleaning procedures in place, use appropriate cleaning products, ensure staff know when equipment requires thorough washing rather than simply wiping down, replace cleaning cloths regularly, and give extra attention to high-risk food preparation areas where cross-contamination is more likely to occur. |
|
Safe food storage |
Safe storage is a key part of effective allergen management. Wherever possible, allergenic ingredients should be stored separately from allergen-free foods in clearly labelled containers. Positioning allergenic products below allergen-free ingredients also helps prevent accidental contamination from spills or leaks during storage. |
Common allergens found in catering environments
The UK requires food businesses to identify the following 14 allergens:
- Celery
- Cereals containing gluten
- Crustaceans
- Eggs
- Fish
- Lupin
- Milk
- Molluscs
- Mustard
- Peanuts
- Sesame
- Soya
- Sulphur dioxide and sulphites
- Tree nuts
Understanding where these allergens appear within recipes and prepared foods is essential for accurate communication with customers.
Practical products that support allergen control
Having the right equipment is one of the simplest and most effective ways to strengthen allergen management within any catering environment. Dedicated allergen control products help staff follow established procedures consistently, reducing the likelihood of mistakes during food preparation, storage and service. By implementing colour-coded equipment and clear identification systems, businesses can create safer workflows that minimise the risk of allergen cross-contamination while making it easier for staff to identify the correct tools and ingredients at every stage of the food preparation process.
A comprehensive allergen management system may include purple allergen chopping boards, dedicated knives and utensils, allergen-safe food storage containers, reusable food rotation and allergen labels, allergen warning signs, ingredient identification labels, hand hygiene products, cleaning chemicals and sanitisers, staff allergen awareness training, and allergen testing kits where appropriate. Together, these products support a consistent, easy-to-follow approach to allergen control, helping food businesses meet their legal responsibilities, improve operational standards and provide greater confidence for customers with food allergies.
The cost of getting it wrong
Poor allergen management can result in:
- Serious illness or death.
- Criminal prosecution.
- Enforcement action by local authorities.
- Financial penalties.
- Civil claims.
- Reputational damage.
- Loss of customer trust.
By contrast, investing in training, procedures and suitable allergen control products helps demonstrate due diligence and creates a safer environment for both staff and customers.
Preparing for the future
As allergen awareness continues to grow, food businesses should treat allergen management as an ongoing process rather than a one-off exercise.
Regular staff training, documented procedures, appropriate equipment and effective cleaning all work together to reduce the risk of cross-contamination.
Whether you are reviewing your current food safety procedures or preparing for changing expectations across the industry, now is the ideal time to strengthen your allergen management system.
A well-managed allergen control programme not only helps you meet your legal responsibilities but also gives customers confidence that their food is being prepared safely and responsibly.
