Can you spot all the 14 food allergens before they reach your guests’ plates? If you manage a food business, especially within events or catering, knowing every major allergen, and their sneaky hiding spots, is not just best practice, it is a legal requirement. I’ve seen, time and again, how one missed label or hidden sauce can put guests at risk and leave teams scrambling.

Why the 14 Major Food Allergens Matter for Food Businesses
Ignoring a food allergen can lead to disaster. Developing a comprehensive food safety management system ensures that risks are mitigated before they reach the table. One slip in your label or kitchen process risks a guest’s life. The Food Standards Agency requires all food businesses to declare the 14 major food allergens when they’re present, whether in a restaurant, food truck, or pop-up event.
I’ve seen first-hand how food allergies can turn a celebration into an emergency. One of the most common mistakes? Hidden ingredients. Sauces and soups often contain allergens you wouldn’t expect.
- Always check your labels, especially on pre-packaged food and sauces.
- Many sauces and relishes sneak in mustard, sesame, or soya.
For those running events, our Highfield-accredited training covers everything from allergen management to food information regulation. We give your team the tools to keep guests safe and compliant. Understanding how you can get a food hygiene certificate in the UK is a vital part of this process. I’ve seen first-hand how food allergies can turn a celebration into an emergency.

Allergen Control: Safety Tips and Professional Tools
Allergens must be managed at every stage of food preparation. I recommend:
- Double-checking all labels for every ingredient.
- Keeping allergen information visible in prep and service areas.
- Using colour-coded, UKAS-certified thermometers and temperature monitoring probes. Browse our professional shop for the right equipment, for example, our infrared probe is ideal for checking surface temperatures on allergen-free prep stations.

Essential Compliance: What Food Businesses Must Do
Every food business must:
- Provide clear, accurate allergen information on all food labels and menus.
- Train staff on the 14 major food allergens and how to prevent cross-contamination.
- Keep allergen information up to date and visible for all staff and customers.
Failing to comply with the Food Information Regulation can lead to fines and, most importantly, put lives at risk. For a safer, more confident kitchen, book our accredited training or contact us for a compliance audit.
