Parkinson’s disease is consistently linked to pesticide exposure, putting Rio Grande Valley farmworkers at risk
Texas Tribune – Health · By By Daisy Yuhas, Public Health Watch · June 5, 2026
In plain language
Researchers are investigating a strong link between pesticide exposure and Parkinson’s disease in the Texas Rio Grande Valley. Studies suggest that 80% of Parkinson’s cases are caused by environmental factors rather than genetics. Farmworkers and families living near agricultural fields face the highest risk because chemicals can travel through the air into nearby neighborhoods and schools. Local residents often struggle to get help because the region lacks enough specialized doctors to diagnose and treat this complex movement disorder.
