Identification of two metallothioneins as novel inhalative coffee allergens cof a 2 and cof a 3.

Background: Dust of green coffee beans is known to be a relevant cause for occupational allergic disorders in coffee industry workers. Recently, we described the first coffee allergen (Cof a 1) establishing an allergenic potential of green coffee dust.

Objective: Our aim was to identify allergenic components of green coffee in order to enhance inhalative coffee allergy diagnosis.
