Predicting occupational allergy in culinary and hairdressing apprentices

Area of Science:

• Occupational health
• Allergology
• Vocational training safety

Background:

• Apprentices encounter workplace allergens similar to professionals, risking occupational allergy.
• Exposure to high molecular weight allergens (HMW-A) and low molecular weight allergens (LMW-A) poses a significant risk.
• Vocational training environments like culinary and hairdressing schools are key settings for this exposure.

Purpose of the Study:

• To evaluate and compare work-related allergy symptoms in apprentices exposed to HMW-A and LMW-A.
• To assess symptom prevalence during the first and second years of vocational training.
• To identify specific allergic manifestations linked to different allergen types.

Main Methods:

• Questionnaires administered to culinary and hairdressing apprentices (1st and 2nd year).
• Spirometry, skin prick tests, and IgE blood tests conducted on first-year apprentices.
• Assessment of allergy-like symptoms, including respiratory and skin conditions.

Main Results:

• First-year apprentices exposed to HMW-A showed higher hypersensitivity to occupational allergens than those exposed to LMW-A.
• Apprentices exposed to LMW-A reported increased skin disorders and upper respiratory symptoms over two years.
• HMW-A exposure was linked to rhino-conjunctivitis and dyspnea, while LMW-A exposure was associated with skin symptoms.

Conclusions:

• Occupational allergy is a concern for apprentices exposed to both HMW-A and LMW-A.
• Early identification and management of occupational allergy are crucial.
• Periodic skin and respiratory health surveillance programs are recommended for apprentices.
