Spray, pray, and litigate
Thousands of U.S. farmers have Parkinson's. They blame a deadly pesticide
Farmers point at a toxic spray; commenters ask why America still allows it
TLDR: Paraquat, a toxic weed killer linked in lawsuits to Parkinson’s, is banned in many countries but still sold in the U.S., with manufacturers denying a causal link. Commenters erupted over the gap between bans and “peer review,” blasting corporate spin and regulators while sharing environmental contamination concerns.
An investigation into paraquat, a super‑toxic weed killer tied to thousands of U.S. lawsuits and heartbreaking farmer stories, lit up the comments with rage, receipts, and disbelief. While Syngenta says there’s “no evidence” paraquat causes Parkinson’s and Chevron insists it shouldn’t be liable, the crowd wasn’t buying the PR. One user demanded to know how a chemical “banned in dozens of countries” keeps getting a pass here, calling out the peer‑review dodge. Another pointed out the whiplash irony: paraquat is banned in China, where it’s made, yet still sold in the U.S.—cue accusations of regulatory capture and political foot‑dragging.
The vibe turned Erin Brockovich‑meets‑Hacker News fast. A commenter who dug deep said they reluctantly concluded “big corporations are the baddies,” invoking “cancer alley” and accusing industry of paying for spin. Others dropped archived links and a related thread arguing Parkinson’s might be in the water—not just in our genes—linking the dots. Dark humor bubbled up, with users mocking “safe when used as directed” as basically “safe if you don’t breathe.”
The drama: bans abroad vs. sales at home, courtroom battles vs. lab consensus, and farmers’ lives upended while the science is debated. The community split between “show me peer review” and “how many countries need to ban it before we act?”—but nearly everyone agreed the stakes couldn’t be higher.
Key Points
- •Paraquat, a highly toxic herbicide, is at the center of thousands of U.S. lawsuits alleging a link to Parkinson’s disease.
- •Despite bans in dozens of countries, including the UK and China, paraquat continues to be sold in the United States.
- •Syngenta (manufacturer) and Chevron USA (a past seller) are defendants; both deny that scientific evidence shows paraquat causes Parkinson’s.
- •Personal cases, including those of farmers Paul Friday and Jim Krause, illustrate alleged exposure and subsequent Parkinson’s diagnoses.
- •More than 6,400 cases are pending in the Southern District of Illinois, with additional suits in Pennsylvania (~1,300) and California (~450).
