Contact allergy to propolis in beekeepers.

Area of Science:

• Allergy and Immunology
• Occupational Health
• Dermatology

Background:

• Propolis, a bee product, is increasingly used in consumer goods and supplements.
• While propolis is a known contact allergen, its prevalence in specific populations like beekeepers remains understudied.

Purpose of the Study:

• To determine the prevalence of propolis contact allergy among German beekeepers.
• To investigate associations between propolis allergy and environmental, physical, and mental health factors in this cohort.

Main Methods:

• A questionnaire, including a validated emotional stability scale, was distributed to 35,000 German beekeeping journal subscribers.
• A reference group also completed the questionnaire.

Main Results:

• Out of 1051 returned questionnaires, 37 beekeepers (3.6%) reported allergic reactions to propolis.
• Propolis allergy was significantly linked to lung diseases and other allergies.
• Only 27% of affected beekeepers recognized their allergy prior to the study; some exhibited greater emotional instability and less hand protection.

Conclusions:

• Contact allergy to propolis is a prevalent issue among beekeepers.
• There is a notable lack of recognition and inadequate self-protection regarding propolis allergy within this occupational group.
