Coffee worker's allergy.

K Osterman, O Zetterström, S G Johansson

    Allergy
    |July 1, 1982
    PubMed
    Summary

    Workers in the coffee industry may develop allergies from raw coffee bean dust and castor bean allergens. Sensitization is linked to atopy, exposure levels, and smoking, impacting respiratory and skin health.

    Area of Science:

    • Occupational Health
    • Allergology
    • Industrial Hygiene

    Background:

    • The coffee industry involves handling raw materials that can contain allergens.
    • Workers may be exposed to airborne dust containing potential sensitizers.
    • Understanding occupational allergies is crucial for worker protection.

    Purpose of the Study:

    • To investigate allergic sensitization in coffee industry workers.
    • To identify specific allergens responsible for occupational symptoms.
    • To explore factors predisposing workers to sensitization.

    Main Methods:

    • Two studies were conducted: a case-control study (Study I) and a cross-sectional study (Study II).
    • Skin prick tests and Radioallergosorbent tests (RAST) were used with factory dust extracts and castor bean (CB).
    • Data on symptoms, exposure, atopic status, and smoking habits were collected.

    Main Results:

    • Over 40% of workers reported occupationally related symptoms like asthma, rhinitis, conjunctivitis, or pruritus.
    • Sensitization to one or two allergens was found in about half of symptomatic workers.
    • Identified allergens included a coffee bean-derived substance (present in raw bean dust) and a castor bean allergen (likely from sacks).

    Conclusions:

    • Occupational exposure in the coffee industry can lead to allergic sensitization.
    • Key allergens are associated with raw coffee beans and castor beans.
    • Atopy, exposure duration/intensity, and smoking are significant predisposing factors for sensitization.
