alt Hacker NewsThousands of U.S. farmers have Parkinson's. They blame a deadly pesticide

There is so much evidence of this connection piling up ..
E.g.:
Proximity to golf courses where pesticides are used -> Parkinson: https://news.ycombinator.com/item?id=43933580
Farmers using pesticides have 60% higher Parkinson risk (2019): https://nos.nl/artikel/2302396-landbouwgif-kan-kans-op-parki... (Dutch)
Parkinson should be labeled as profession-linked disease for farmers(Swiss): https://www.srf.ch/news/schweiz/pestizide-als-krankmacher-pa...
An excellent movie on basically the same topic is Michael Clayton, with George Clooney, Tom Wilkinson, and Tilda Swinton in IMO each of their best career performances.
"Critics point to research linking paraquat exposure to Parkinson’s, while the manufacturer pushes back, saying none of it is peer-reviewed."
What lead it to being "banned in dozens of countries all over the world, including the United Kingdom and China"?
> While Chinese companies supply paraquat to American farmers, the report points out China is also a big purchaser of crops, like soybeans, that are grown with help from the pesticide.
> “In these two ways, China economically benefits from the application of paraquat in the U.S., where it outsources many of its associated health hazards,” the report said.
There would arguably be a poetic justice to the US taking a turn at bearing health and environmental costs to benefit other nations, but it's not right for that to happen to any country.
I got shingles-ish rash after sitting in an outdoor jacuzzi in Salinas, California. Visited the urgent care and the Standard-trained doctor of immigrant farm laborers said it was related to the pesticides. Said he lost both parents in their 40s and suspects it was the indiscriminate spraying from the air in the 70/80/90s. Eye-opening and thought-provoking.
Isn't this old news? If you are a Vietnam vet who were exposed to Agent Orange or other herbicides, and you get Parkinson's, the VA assumes it was from Vietnam. My grandfather had Parkinson's a long time ago it was always said it was due to pesticides they used while farming.
One of my relatives owned an animal farm for a couple of decades and got a very rare muscle wasting disease. A high school friend of his, who was also a farmer, got the same disease. I imagine there were innumerable harmful chemicals on the land and in the water from decades of use before he bought it in the 90s.
The chance this is a trustworthy source for me is close to 0. This just sound like fantastic pseudology:
“Even secondary exposure can be dangerous. One case published in the Rhode Island Medical Journal described an instance where a 50-year-old man accidentally ingested paraquat, and the nurse treating him was burned by his urine that splashed onto her forearms. Within a day, her skin blistered and sloughed off.
Too bad they voted to eliminate accountability for businesses that poison people.
Now they get to find out.
I looked up this pesticide. It is banned in EU. Not exactly surprising.

ChubbyEmu video for "A Farmer Mistakenly Drank His Own Herbicide. This Is What Happened To His Brain."
"With evidence of its harms stacking up, it’s already been banned in dozens of countries all over the world, including the United Kingdom and China, where it’s made. Yet last year, its manufacturer Syngenta, a subsidiary of a company owned by the Chinese government, continued selling paraquat in the United States and other nations that haven’t banned it."
The government absolutely cannot be trusted to protect the individual, whether a farmer or a consumer. It is coming down to each individual protecting himself by assessing the safety of the ingredients, sometimes also the purity.
>Chevron, which never manufactured paraquat and hasn’t sold it since 1986 ... should not be liable
I think Chevron may have a point, no one knew back then and they stopped selling it ~40 years ago. But ---
To me, if the US had a real Health Care System, people would not have to file lawsuits to get the care they need.
But in the US, this is how things work. The care these people need is unaffordable by everyone in the US except for the very rich. So they will be waiting probably 10 to 20 years for relief as the lawsuit works it way through the courts and appeals.

Here in Germany, farmers are regularly complaining about all the bureaucracy and "unnecessary" safety requirements in regards to pesticides and over-fertilization . But they also complain when nothing grows anymore because they killed the top soil with too much fertilizer, poisoned the groundwater and then die of Parkinson because, who would have thought, all those regulations and safety requirements had a point after all. I don't know how to help those people, I really don't.
I honestly think there's a technology / robotics solution to the pesticide, and especially herbicide, problems. I'm in completely the wrong space to see it happen, but I'm still hopeful someone smart can do it.
I just read another article about this, but the affected group is military from Camp Legume. The water in Legume was contaminated, and its actually given a control group test for the incidence of Parkinson’s with Camp Pendleton, where the water was not contaminated.
Spoiler: it looks like the farmers are right

Amazing thing is TCE was banned by the Biden EPA in 2024 and Trump’s EPA stopped its ban.
Here's some of the research linked in the article.
"Rotenone, Paraquat, and Parkinson’s Disease" - https://pmc.ncbi.nlm.nih.gov/articles/PMC3114824/
"In 110 PD cases and 358 controls, PD was associated with use of a group of pesticides that inhibit mitochondrial complex I [odds ratio (OR) = 1.7; 95% confidence interval (CI), 1.0–2.8] including rotenone (OR = 2.5; 95% CI, 1.3–4.7) and with use of a group of pesticides that cause oxidative stress (OR = 2.0; 95% CI, 1.2–3.6), including paraquat (OR = 2.5; 95% CI, 1.4–4.7)."
"Agricultural paraquat dichloride use and Parkinson's disease in California's Central Valley" - https://pubmed.ncbi.nlm.nih.gov/38309714/#full-view-affiliat...
"Ambient paraquat exposure assessed at both residence and workplace was associated with PD, based on several different exposure measures. The PD patients both lived and worked near agricultural facilities applying greater amounts of the herbicide than community controls. For workplace proximity to commercial applications since 1974, working near paraquat applications every year in the window [odds ratio (OR) = 2.15, 95% confidence interval (CI) = 1.46, 3.19] and a higher average intensity of exposure [per 10 pounds (4.54 kilograms), OR = 2.08, 95% CI = 1.31, 3.38] were both associated with an increased odds of PD. Similar associations were observed for residential proximity (duration: OR = 1.91, 95% CI = 1.30, 2.83; average intensity: OR = 1.72, 95% CI = 0.99, 3.04). Risk estimates were comparable for men and women, and the strongest odds were observed for those diagnosed at ≤60 years of age."
"Department of Pesticide Regulation Releases Preliminary Findings from Review of Environmental and Human Health Studies Related to the Use of the Pesticide Paraquat" - https://www.cdpr.ca.gov/2024/12/30/department-of-pesticide-r...
"DPR’s preliminary scientific evaluation found that the current registered uses of paraquat in California may adversely affect non-target organisms, including birds, mammals and aquatic organisms, with the most significant risks to birds. Additional mitigation measures, beyond current restrictions on paraquat use currently in effect, may not feasibly reduce these environmental impacts to acceptable levels.
Consistent with United States Environmental Protection Agency’s (U.S. EPA) 2019 review, DPR’s review of existing human health studies does not indicate a causal association between paraquat exposure and Parkinson’s disease."
The chemical manufacturer, Syngenta, is the same one involved in the creation of atrazine, the chemical notorious for preliminary evidence of the whole frog sex-changing while it's been sprayed all over the US but banned in most other countries.
This reminded me that the current administration has approved PFAS pesticides aka forever chemicals which are linked to certain cancers. What could possibly go wrong. https://time.com/7336883/epa-pfas-pesticides-health-risks/
Many medical preparations are oil rather than water soluble. Seed oils tend to be the cheapest choice, and probably still have trace amounts of pesticides/herbicides/fungicide--even after processing. Under such conditions, one must wonder how many of our modern neurodegenerative conditions are iatrogenic. Genetics may load the chamber, but environment pulls the trigger.
I was casually chatting with my uncle who is a doctor, he says something along the lines that if a chemical can kill a rat or a mosquito, to assume it won't do any damage to humans is kind of hilarious.
Of course humans who inhale this thing in small quantities won't die, but you can be sure they will kill some tissues that they go into. Now comes another problem of regular exposure, and these chemicals having an entry, but no exit path. That just means there are tissues, that are likely dying out every time there is a exposure.
Again none of this might kill you at the first exposure, but if there are enough dead tissues, there sure is likely to be things like Parkinson's or may be even diabetes.
Im guessing combined with this, if you already some bad genetics it could cause issues like these.
It's a herbicide, not a pesticide. I clicked the article because I was surprised that any current pesticides are that harmful to humans.
Pesticides are, generally, safe to humans. Herbicides are, generally, not at all safe to humans. Roundup is probably the most safe outside of per-emergents like corn husks or whatever, but it's not a free ride either.
Paraquat seems like it should be banned on its acute toxicity grounds alone, but the Parkinson's link as phrased doesn't stand out given the article's statistics. A thousand out of a million is a thousandth.
A baseline rate or Parkinsons would be a good addition to the article. I have seen figures of 1 out of 331 for total or apparently about 1.1M total. Farmers make up about 2% of the population. Doing rough back of envelope math shows that you would expect 22K farmers to have Parkinsons assuming even distribution by population. The numbers aren't precise but if the article's thousands was taken literally it would ironically suggest paraquat has a protective effect against Parkinsons which is obviously absurd thing to assume from a known neurotoxin.
Not every farmer with Parkinsons is suing though. If we assume 1% of farmers are involved in lawsuits then thousands is alarming because it would imply 10x rates. 10% suing though and it is expected. 100% suing would be 1/10th the general rate which would fit with the absurd counterfactual hypothesis that non-lethal paraquat exposure prevents Parkinsons.
propublica.org has endless great articles on this and other horrors in the US
but if we aren't going to change a damn thing with daily mass shooting we sure aren't going to fix poisoning the environment, fracking is 100x worse than this and "sacrifice zones" are a real thing
follow the money, sue before current administration makes it illegal to sue
Huh.
Poisons are poison!
And they sprayed this shit all over themselves and people nearby.
Meanwhile, RFK is too busy talking vaccines and beef tallow...
Am I the only one that thinks it's weird to call a weed killer a pesticide?
Are the migrant workers getting Parkinson's, or only the white males who can pull the heartstrings of MAGA folks?
1 in 400 US citizens is diagnosed with parkinsons, if by "thousands", this headline means 5000, then 1 in 2000 US farmers has Parkinson's. Stop it.
Reminds me of "cancer alley" [1].
As somebody who's looked in to this a bit, the deeper I dug the more I ultimately moved toward the conclusion (reluctantly) that indeed big corporations are the baddies. I have an instinct to steel-math both sides, but not every issue has two compelling sides to it...
One example of them clearly being the baddies is them paying people to social media astroturf to defend the roundup pesticide online [2].
