Skepticism is healthy. You've found that the numbers don't make sense at face value. The problem is that you stopped there, you haven't even made any attempt at reconciling them with the original claim.
What if the US number of 1 in 400 figure is that high precisely because it includes people exposed to pesticide? In other words, maybe the number would be 1 in 500 if it weren't for Paraquat? You'd have to look at concentration maps or at the very least check what's the diagnosis rates in other countries before you can truly dismiss the claim, imho.
The article already talks to the numbers they mean and what scale they believe it to be:
> More than 6,400 lawsuits against Syngenta and Chevron that allege a link between paraquat and Parkinson’s are pending in the U.S. District Court of Southern Illinois. Another 1,300 cases have been brought in Pennsylvania, 450 in California and more are scattered throughout state courts.
> “I do think it’s important to be clear that number is probably not even close to representative of how many people have been impacted by this,” said Christian Simmons, a legal expert for Drugwatch.
I'm not saying you have to believe it, just that rhetorically asking if it's more than 5,000 in the US is redundant when the article already says there are more than that many individual cases about it in a single district court.
My grandfather was a crop duster pilot in the 60s-70s. He died of Parkinson's almost 4 years ago today. He is the only one in my family to succumb to this disease. For a brief moment I was relieved to know there was some explanation for his suffering.
Then I read the HN comments.
It is beyond infuriating to read a well researched paper with 1300 open cases legal with overwhelming evidence only to be met with "zero chance this is real."
The article mentions epidemiological studies showing that people living or working near farmland where paraquat is used have a higher incidence of Parkinson's.
Don't be so quick to dismiss it, there could be a link.
