Background: Farmworkers’ children are at particular risk for pesticide exposure. In addition to food and water contamination, agricultural drift, and overspray, they may be exposed to pesticide residues carried into their homes on the clothing, shoes, and skin of parents who work in agricultural fields. Farmworkers may be able to reduce children’s exposure by limiting these “take-home” exposures. Recommended practices include wearing protective clothing, removing shoes before entering the home, and showering soon after work.

Objective: This study examines associations between farmworkers’ practices and levels of the organophosphate pesticide azinphos-methyl in house dust.

Methods: Questionnaire-based interviews and dust samples were obtained from 210 farmworker households with young children in the lower Yakima Valley of Washington State. Sufficient amounts of dust for analysis were gathered from children’s play areas in 156 homes. Interviews included questions about sociodemographic characteristics, agricultural tasks, perceived pesticide exposure, home practices, and residential proximity to fields.

Results: Detectable levels of azinphos-methyl were found in 85% of the house dust samples. All surveyed farmworkers were exposed to pesticides during the past year; more than a fifth (22.4%) reported conducting tasks involving high pesticide exposure. Although employers provided approximately 80% of those working directly with pesticides with gloves, less than 65% were given boots and coveralls. Less than 40% of fieldworkers wore boots or gloves. Sixty percent of farmworkers removed their shoes before entering their homes, and 47% showered within an hour after work. This session will consider associations between household pesticide levels and farmworkers’ practices.

Learning Objectives: At the conclusion of the session, participants will be able to: *Summarize current knowledge regarding effects of exposure to organophosphate pesticides on child health. *Describe farmworkers' occupational tasks, usage of protective equipment, and home practices. *Assess the relationship between farmworkers' practices and household pesticide levels. *Develop recommendations for community and/or workplace interventions.
