Title Contact dermatitis among cashew nut workers
Bibliographic information Aug. 1996, Vol.35, No.2, p.114-115. 14 ref.
Abstract Anacardic acid and cardol, the main cashew nut shell liquid (CNSL) components are the main cause of occupational contact dermatitis in cashew nut workers, acting as both irritants and sensitizers. A study was carried out at the Cashew Nut Exportation Company of Fortaleza, Brazil. The workers, all female, were interviewed and examined. Those with hand dermatitis were selected for patch testing with a standard and an additional series. The following additional substances were applied: cardol, cardanol, o-methyl-cardanol, anacardic acid, and hydrogenated cardanol, all at 1% and 2% pet. Readings were made at four days. Ten control subjects were also tested. The results confirm the sensitizing power of cardol and indicate that positivity to cardol is present only in patients who touch natural CNSL before it is heated.
