First seen Jun 27, 2026 · Last updated Aug 14, 2026 · Updated 3 times

Summary

This study follows nearly 90,000 farmers and their spouses to track long-term health effects of pesticides, crops, and animals. Participants report new medical conditions, which researchers then confirm through medical records and genetic samples. The goal is to better understand diseases like asthma and Parkinson's in this group.
