AB  - We report a case of occupational asthma due to hidden casein, contained in a dermatological powder. A 44 year old nurse reported the recent onset of rhinitis and asthma, clearly related to the work environment. Skin tests for food allergens revealed a positivity for milk proteins. The source of dispersed milk proteins in the work environment was found to be a dermatological formulation of an inert refreshing powder, used to treat excoriated areas in the elderly. Skin prick tests confirmed the positivity to casein and to the commercial product.
