Carbaryl, a widely used insecticide, is reputed to have a wide safety margin. It can induce acute cholinesterase poisoning, which is rapidly reversible on discontinuation of exposure. Long-term sequelae from long-term exposure have not previously been described in humans. This report describes the experience of a 75-year-old man who had long-term excessive exposure to carbaryl and in whom a debilitating syndrome, including headaches, memory loss, proximal muscle weakness, muscle fasciculation, muscle cramps, and anorexia with marked weight loss, developed. At the time of diagnosis, serum pseudocholinesterase levels were low, and his major symptoms resolved on termination of exposure. Late clinical features were sleep apnea and progressive development of a peripheral neuropathy. The difficulty in diagnosing the cause of a group of relatively nonspecific symptoms raises the question of whether chronic carbaryl neurotoxicity might be occurring more frequently than previously suspected.
