The scope, occurrence, recognition and control of acute occupational pesticide poisoning were reviewed, along with the requirement under the Texas Occupational Disease Reporting Act of 1985 that such poisonings be reported. The characteristics of acute pesticide poisoning were listed for the following chemical groups: chlorinated hydrocarbons, organophosphates, carbamates, halocarbon and sulfuryl fumigants, phosphine fumigants, cyanide fumigants, nitrophenolic and nitrocresolic herbicides, chlorophenoxy compounds, and dipyridyls, including their pharmacologic action or site of toxicity, route of absorption, major acute signs and symptoms, and laboratory tests for diagnosis. Farm workers can be exposed through three major routes: oral, respiratory, and dermal. Specific workers at risk for exposure to these types of chemicals include ground applicators, gardeners and nurserymen, harvesters or field workers, warehousemen who handle and transport pesticides, formulators and manufacturers, fumigators, aerial applicators, and sometimes police and fire fighters. In Texas alone a 1982 study indicated that 27 different formulating establishments existed with a total of 2,600 employees of whom 1,600 were production workers. Various regulations have been drafted to aid in controlling pesticide exposure, including permissible exposure limits for many pesticides. Under the new law, physicians and directors of laboratories with case reports must report acute occupational pesticide poisonings in the state of Texas. These are then forwarded to the Epidemiology Division of the Texas Department of Health, in Austin.
