Pesticide exposure linked to up to 70% higher ALS risk, global study finds

A global analysis of ALS studies over 35 years finds occupational pesticide exposure is linked to a 61%–71% higher risk of developing ALS, with higher risk tied to greater exposure and a stronger signal in men; glyphosate and other herbicides are implicated, and farmworkers face higher exposure, while pesticide use continues worldwide even as US use declines; ALS is a fatal neurodegenerative disease and may be part of broader health concerns linked to pesticides.
