Why do we have 14 allergens?

Have you ever found that as your food allergy is not on the top 14 allergen list you are taken less seriously at work or school, by friends, family or your GP? 

If the food you are allergic to does not need to be labelled it must be less serious, right? This kind of thinking could have significant consequences for the person suffering from the allergy.  Many people living without allergies don’t realise that you can have anaphylactic reactions to food that are not in the top 14. 

How were the top 14 allergens decided upon?

In 2003 12 top allergens were covered in Annex IIIa of the EU directive 2003/89/EC which is the directive which covers the labelling of allergens in food.  The original 12 in 2003 were

  1. Cereals containing gluten
  2. Crustaceans
  3. Eggs
  4. Fish
  5. Peanuts
  6. Soybeans
  7. Milk
  8. Tree nuts
  9. Celery
  10. Mustard
  11. Sesame Seeds
  12. Sulphur Dioxide

This was not a static list and work into better understanding of food allergies across Europe continued.

EuroPrevall was a large-scale study which launched in June 2005 across Europe.  It consisted of 3 main parts, birth cohort studies, Community Studies and Outpatient Clinic Studies.  The project was funded by the EU to inform on the bigger picture surrounding the incidence of allergic reactions to food in different European countries, advise on the effect of allergies on the quality of life of sufferers, standardising allergy diagnosis and work towards making standardised food labelling across the EU.

In January 2008 a proposal was put forward by the European Commission to look at labelling issues which had arisen since the last EU directive and reviewing all the new allergy research in the EuroPrevall studies.  This was discussed in 2011 by European Parliament and EU Regulation 1169/2011 was published in November 2011.  These directives were more explicit in what was covered by the regulations.  At this time Molluscs and Lupin were added to the original 12, taking the number of allergens to be labelled up to 14.

What do countries on other continents label?

The EU has regulations on 14 allergens, compared to the US which has 8 and Japan which has 7 (mandatory labelling for the 7 allergens shown in the table below and voluntary labelling for a further 20 allergens).

Many countries don’t have labelling laws at all.  The EU likely has more as it covers a more diverse group of cultures than Australia and the US which means different European countries have different eating habits.

I would love to hear from you if I missed out your country, let us know what the regulations for labelling allergens are where you live!

Are we done?

No, the list of allergens is unlikely to remain static.  The EuroPrevall studies may have concluded, but there is another large-scale follow-up study called iFAMM, Integrated Approaches to Food Allergen and Allergy Risk Management.  This newer study will incorporate study data from the US and Australia as well as continuing studies in Europe.

Does your food allergy make the top 14 or are you allergic to something more unusual?  Let me know on Twitter, Facebook or comment below, I am always interested to hear from you!

New to food allergies? How to get started

Have you just been diagnosed with a food or environmental allergy?  Welcome to the allergy community!

How did I start?

Nearly 10 years ago, my lovely 5-month-old daughter had dairy for the first time and was rushed to our local hospital after having a severe allergic reaction.  I was in limbo for a short time where I didn’t know what to feed her, what food we should be avoiding, and I didn’t know anyone else who had experienced the same thing. My GP, health visitor and hospital all failed to give me the right information to help feed my baby safely. So where did I look?

As I am based in the UK I found the best places to start were

But I also used more global resources by looking at

I hope you also find this to be a good jumping off point.

At the moment there is plenty of information on Twitter and a large allergy community there (which I wish was the case 10 years ago when I started) and I was surprised to find a lot of information on Pinterest, especially if you are looking for special recipes avoiding multiple allergens. It’s another wonderful resource.

I have to say though my primary resource for information continues to be Facebook groups , especially if you join one based in your country.  I am now only in 2 groups on Facebook which I continue to find useful as my daughter heads towards her tweens and teens.

Please come and join one of our groups, especially if you are struggling with a newly diagnosed child, introduce yourself, let us know what allergies you have and you will often find multiple members of the group willing to offer help and advice.

Let me know in the comments what websites you have found useful.



Welcome to my new allergy blog!

I have lots of great ideas of things to research and write about – I intend to look into the UK’s top 14 allergens in more depth, continue to write about more unusual allergies and help you find the information you need to live a healthy life with allergies.
