This chapter focuses on the use of pesticides in domestic food and pet species. Pesticides are frequently topically applied or orally administered to animals to control harmful insects and parasites or used in their environment to control a variety of pests. The rural setting of food-producing and livestock-rearing operations results in exposure of domestic animals to the wide array of agricultural chemicals currently in use. In addition, wildlife species are often exposed accidentally or maliciously to pesticides, especially those used in animal and plant agriculture. Pesticide exposures can be minimal or can be sufficiently great to produce clinical signs and result in acute poisoning, delayed toxicity, or residues that affect public safety through contamination of the food chain. The likelihood of intoxication depends on a variety of physiological, behavioral, and environmental factors. Fortunately, the emergence of less toxic pesticides for veterinary use has resulted in less frequent acute animal intoxications. Chronic exposure to pesticides applied to lawns has been hypothesized as a cause of bladder cancer in certain dog breeds, although this remains controversial. The diagnosis of pesticide intoxication requires careful antemortem and postmortem investigation. Treatment of intoxicated animals involves early decontamination, symptomatic and supportive care, and, in some cases, antidote administration.
