Argan, a new cause of occupational asthma in cosmetic manufacture

Good evidence of a new cause of occupational asthma from Argan, derived from the nuts of the tree Argania Spinosa. It is used in cosmetics. All 9 exposed workers had positive skin prick tests, 3 had positive immediate asthmatic reactions during challenge tests, and one rhinitis. The allergens cross-reacted with hazel nut allergens.
