Title Irritant contact dermatitis caused by needle-like calcium oxalate crystals, raphides, in Agave tequilana among workers in tequila distilleries and agave plantations
Bibliographic information Feb. 2001, Vol.44, No.2, p.94-96. Illus. 15 ref.
Abstract Needle-like calcium oxalate crystals, such as raphides, are found abundantly in all tissues of Agave tequilana plants; thus, 1 droplet (0.03mL) of juice pressed from leaves contains 100-150 crystals, 30-500Ám in length, sharpened at both ends. In tequila distilleries, 5/6 of the workers who handle agave stems have experienced the characteristic irritation. In contrast, only one third of workers in agave plantations involved in harvesting agave plants complain of the irritation. This questionnaire study confirms that all the irritation suffered in both distilleries and plantations takes place at bodily locations where the plants come into contact with the workers' skin in the course of their work.
