CELERY

What is it?

Celery is a member of the plant family and is composed of a root (celeriac), sticks, leaves and seeds. The majority of people are allergic to the root

Celery can cause a reaction when raw or cooked


What do I need to know?

If someone has an allergy to celery, it is highly likely that they will also react to some pollens from other plants (Anaphylaxis Campaign 2014)

Celery can also trigger oral allergy syndrome (OAS) which is caused by some raw fruits, vegetable and nuts. If it is just OAS, then there is no reaction when these foods are cooked or processed (e.g. jam, fruit juice). Symptoms affect the mouth, specifically the tongue and back of the mouth (BSACI 2016)

Celery allergy is viewed as a serious problem in Germany, Switzerland and France. It is rarer in the UK, prevalence currently unknown (Anaphylaxis Campaign 2014)

It is important to see your GP as soon as possible if you think you may have an allergy to celery/celeriac as the symptoms can be severe. They are likely to refer you on to an Allergy Clinic (Anaphylaxis Campaign 2014)

Since November 2005, it has been a legal requirement to specify celery in pre-packed foods (Food Standards Agency 2016)
