CELERY ALLERGY


Key Allergens

In the UK celery is listed as a top 14 allergen which needs to be labelled in packaged food.

There are 6 allergens associated with celery allergy - the main allergen in celery is Api g 1 which is similar in shape to the Bet v 1 allergens which can cause oral allergy type symptoms.

Two of the proteins found in celery are lipid transfer proteins, Api g 2 and 6.

Api g 4 is a profilin protein, these are panallergens and found in many fruits and vegetables.

Celery also contains chemicals called furanocoumarins, these can act as a contact allergen. When they come in contact with the skin it can become more sensitive to sunlight which can cause blistering. This is more common as an occupational allergy with people who pick, pack and process celery. This is known as phototoxicity. Additionally there have been case reports of ingestion of celery causing severe sunburn and blistering in rare cases.

Associated Syndromes

You may have Pollen-Food Allergy Syndrome if you suffer from celery allergy with oral allergy symptoms to 3 or more of the foods mentioned in cross reactivity section.

The lipid transfer proteins in celery may cause problems if you suffer from LTP Syndrome.

Cross Reactivity

If sensitised to birch pollen you may have Pollen Food Allergy Syndrome and may also react to apple, kiwi, pear, peach, plum, nectarine, apricots, cherries, tomato, celery, potato, parsnip, pepper, dill, cumin, peas, coriander, fennel, hazelnut, walnut, almonds, peanuts, lentils and beans.

If sensitised to alder pollen you may also react to apple, cherry, peach, pear, parsley, celery, almonds and hazelnuts.

Common foods involved in LTP allergy include kiwi, strawberries, sunflower seeds, walnut, apple, mulberry, banana, pea, apricot, cherry, plum, almond, peach pomegranate, raspberry, tomato, grape, celery, peanut, asparagus, cabbage, broccoli, chestnut, lemon, tangerine, orange, hazelnut, lettuce, lentils, lupin, green bean, pear, mustard, wheat and maize.

Other foods containing plant profilins are kiwi, pineapple, celery, peanut, chilli, watermelon, orange, hazelnut, melon, strawberry, soya, barley, walnut, lychee, lupin, apple, banana, date, cherry, almond, peach, pear, mustard, tomato, aubergine and wheat.
