Abstract

The California Pesticide Illness Surveillance Program collects, investigates, abstracts, and records reports received from physicians. A minority of the reports are received through the county health officers who are notified by physicians under a state requirement for reporting pesticide-caused conditions. Most of the cases are identified by review of workers' compensation records. All the cases identified are investigated by the agricultural commissioners of the counties where exposure occurred. The investigation reports are reviewed and abstracted by staff of the Worker Health and Safety Branch of the California Department of Pesticide Regulation, California Environmental Protection Agency (Cal/EPA). The crucial determination is assessment of the degree of relationship between the exposure and subsequent disease: definite, probable, possible, unlikely, or unrelated. In most years, the number of cases investigated has been between 2,500 and 3,000. Excluding antimicrobials, the number of cases found after investigation to have a definite, probable, or possible relationship with pesticide exposure has ranged from 970 (in 1989) to 1,372 (in 1988). Cases involving antimicrobials rarely were reported prior to 1987. In that year, surveillance staff began reviewing workers' compensation records personally, with the specific goal of identifying antimicrobial cases. Since then, antimicrobials have been found to account for 746-813 cases annually, primarily involving splashes and squirts to the eye and inhalation of fumes or vapors. Numbers of case reports from agricultural situations have varied irregularly, driven by small numbers of episodes concerning multiple individuals. Variability in numbers of cases involving the skin has depended almost entirely on variation in numbers of field worker dermatitis. The most common situation for field worker dermatitis has been summer work in table grapes grown in the southern San Joaquin valley. In the two years since reentry intervals for the acaricide propargite were lengthened, there have been no more major clusters of field worker dermatitis. Although the cases collected by the surveillance program are predominantly occupational, because of dependence on workers' compensation for case identification, most recorded deaths are nonoccupational. Nonoccupational fatalities include suicides, mistaken ingestion of pesticides (especially if stored in food containers), and entry into structures being fumigated. Occupational deaths are less common and more varied. The circumstances of each reported occupational death are summarized above.
