Chlorinated hydrocarbons, also named organochlorines, have been used for prevention and control of insect infestations around farms, homes and on animals from the 1950s through the 1970s. Chlorinated hydrocarbons include endrin, aldrin, dieldrin, heptachlor, lindane, DDT and endosulfane. Most of these insecticides have been banned because of accumulating tissue residues and environmental persistence. Contaminated soils or leakage from old dump sites are possible sources of exposure for wildlife and domestic carnivores. The most likely source of exposure in dogs and cats is old stockpiles of insecticides and improper waste disposal. In addition, a few of these compounds may still be legal for ectoparasite control in dogs in certain countries. Exposure in dogs and cats may occur by ingestion, inhalation (less likely), or cutaneous absorption when the insecticide is applied topically and accidentally overdosed (Raisbeck, 2006).
