Parkinsonism among Washington State Agricultural Pesticide Handlers

Previous human and animal studies suggest that some pesticides, including those typically applied by agricultural pesticide handlers, may increase the risk of parkinsonism (PS). This study assessed the feasibility of conducting neurological exams on active pesticide handlers, to determine the prevalence PS symptoms.
 
Epidemiological studies suggest a 49% increased risk of PS in individuals who have had chronic occupational exposure to pesticides.

Reducing Agricultural Worker Risks through New and Emerging Technologies

This project evaluated interventions designed to reduce worker exposure and risk during pesticide applications in tree fruit. Bringing together land grant universities, industry, producers, and workers, this work sought to ensure that the decision process used for adopting new pesticide products and new spray technology development includes worker health and safety.

Using IPM to Reduce Pyrethroid Pesticide Exposures in Dairy Workers

This project partners with Washington State University to reduce pesticide use in dairy operations by introducing Integrated Pest Management (IPM) practices in these workplaces. We are working with a network of participants to develop a robust and practical IPM program that provides evidence for cost-effective interventions that can reduce pesticide usage in these farm operations.

Measurement of Farmworker OP Exposure through Protein Adducts

This completed project developed an assay to improve understanding of worker exposures to a wide range of organophosphate (OP) pesticides and advanced the method for potential use in field and clinic settings, providing rapid feedback to workers, clinicians, and physicians.
 
Organophosphorus pesticides (OPs) have widespread commercial application in the U.S. and worldwide.

Improving PPE Effectiveness in Agricultural Applications

This project responds to specified PPE needs for the tree fruit and related industries in Washington State that can reduce pesticide handler exposure and potential pesticide-related illness. Three safety concerns of WA airblast pesticide applicators were addressed: 1) data-driven respirator cartridge change-out schedule, 2) field efficacy of gloves used by pesticide handlers, 3) the effectiveness of a PPE hat that could be used with PPE suits and jackets.

GRAS2P Food Safety Video

This video project integrates current pesticide safety standards into the video, Fieldworker Orientation and Food Safety/Orientation/Orientation para el Trabajador Agricola y Seguridad Alimenticia. The video is bilingual and will be used by growers and workers in Washington and across the United States to ensure effective food safety practices.

Pesticide Exposure Pathways in Agricultural Communities

This sub-project was housed under another program, The Center for Child Environmental Health Risks Research, which worked to understand the mechanisms that define children’s susceptibility to pesticides. Center researchers, including some that also worked at PNASH led field studies with a farmworker community to bring a unique and successful approach to the study of children’s environmental health. This center was funded by the US Environmental Protection Agency (EPA) and NIEHS.
