Thousands of U.S. farmers have Parkinson’s. They blame a deadly pesticide.

Tuesday, December 16, 2025 -Thousands of U.S. farmers are reporting Parkinson’s disease diagnoses that they attribute to prolonged exposure to a widely used pesticide. 

Health experts say mounting evidence links the chemical to neurological damage, prompting calls for stricter regulation and comprehensive studies on long-term agricultural exposures.

Farmers describe years of handling crops treated with the pesticide, often without adequate protective equipment, and now face debilitating symptoms that impact daily life and work. 

Legal actions and advocacy efforts are growing, as affected individuals seek accountability and compensation for what they argue is preventable harm.

The situation underscores the broader public health debate over chemical safety in agriculture. Regulators, scientists, and policymakers are under pressure to balance crop productivity with human health, while the farming community grapples with the devastating personal and economic consequences of exposure.
