The hazard to fieldworkers from the residues of organophosphate pesticides is a classic occupational health issue. Traditionally, the historical development of such issues has three phases or concerns, viz., recognition, evaluation, and control. In an ideal occupational health program, these three phases are cyclic and repetitive in that occupational health problems are typically first recognized by an unusual pattern of morbidity or mortality within an occupational group; the working environment is then evaluated via such samples and measurements as may be available and appropriate to identify and quantify the levels of exposure; control strategies and technologies are then brought into play to reduce these exposures; and in the ideal case, this process is repeated by follow-up biological and environmental monitoring to ensure that the controls are efficacious and sufficient. In the broad history of occupational diseases, these phases have typically spanned many years and rarely if ever have they progressed in a cohesive sequence or from a well-developed plan (Hunter 1978).
