An unusual occurrence of toxaphene poisoning in swine

Ten of 15 sows developed an acute nervous disorder that resembled the effects of water deprivation-salt poisoning. However, a unique set of circumstances had permitted the environmental persistence of a toxaphene-lindane insecticide combination for approximately 1 month, with toxaphene toxicosis resulting. The diagnosis was based on the lack of lesions of salt poisoning and the finding of 4 ppm of toxaphene in the cerebellum and 0.3 ppm of toxaphene in the serum of 1 of the 2 sows that died.
