The authors describe the growth of the Occupational Pesticide Poisoning Surveillance Program at the Texas Department of Health. The program was based on a Sentinel Event Notification System for Occupational Risks(SENSOR) model, using sentinel providers to report cases. The number of confirmed occupational cases increased from 9 workers in 1987 to 99 workers in 1996.

Pesticide Action Network, United Farmworkers of America, and California Rural Legal Assistance Foundation analyzed California government data on agricultural poisonings and enforcement of worker safety standards. Nearly 500 pesticide poisonings were reported for California farmworkers every year. The actual number of pesticide-related illnesses is unknown, since many poisonings go unreported. 

Children encounter pesticides daily and have unique susceptibilities to their potential toxicity. Acute poisoning risks are clear, and understanding of chronic health implications from both acute and chronic exposure are emerging. Epidemiologic evidence demonstrates associations between early life exposure to pesticides and pediatric cancers, decreased cognitive function, and behavioral problems.

Surveillance data show that pesticide-related illness is an important cause of acute morbidity among migrant farm workers in California. Exposures occur in various ways (e.g., residues, drift), suggesting that the use of pesticides creates a hazardous work environment for all farm workers  Improved education for health care providers should be a priority.
