Poppy Seed Allergy

Key Allergens

With the increase in consumption of more vegetarian and vegan foods the use of poppy seeds in foods has increased. It is not considered to be a very common allergen.

Poppy seeds have been found to contain profilin allergens, those especially sensitive to these proteins may have allergic reactions to poppy seeds.

Allergic reactions caused by eating poppy seeds are sometimes thought to be caused by Bet v 1-like proteins, which cause reactions in people sensitised to birch tree pollen and give oral allergy type symptoms.

Recently a study has found that poppy seeds contain 2S albumin proteins, more commonly found in nuts and seeds. Individuals sensitive to these proteins may react to the 2S albumin proteins in the seeds.
