The Healthy Dairy Worker Study

Dairy workers are commonly exposed to microbes and allergens on the job. However, little is known about whether these exposures provide health benefits or contribute to an increased risk of illness. The ‘hygiene hypothesis,’ suggests that exposure to microbes on farms may have immune benefits.

Project Overview

Ergonomic Evaluation of Emerging Mobile Platform Technologies in the Tree Fruit Industry

Tree-fruit activities such as pruning, structural cutting, and green fruit thinning, are high-intensity labor activities traditionally performed on the ground or on ladders. To explore the impact of new technology on worker strain and injury, this project conducted a comparison between three different treatment groups: ground, ladder, and harvest-assisted mobile platforms.

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.

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.

Aggravating Factors of Asthma in a Rural Environment (AFARE)

This community-based project characterized ambient triggers of asthma in the rural setting by following 50 (children and adults) asthmatic community participants, mapping their exacerbations and comparing these with known agricultural exposures. 
 
Communities living in rural agricultural settings may be exposed to an array of biological (e.g. organic dust from animal and crop products, bacteria, fungi, endotoxins) and non-biological particles and gases (e.g. pesticides, hydrogen sulfide and ammonia).
