The fight over Paraquat isn’t over yet. This powerful herbicide, long used in agriculture, has been linked to Parkinson’s disease, and thousands of people exposed to it have filed lawsuits. But after a judge recently dismissed several cases, plaintiffs are pushing back, asking an appeals court to bring those claims back to life before key bellwether trials move forward.
This appeal could be a game-changer. If the ruling stands, it might make it harder for victims to hold Paraquat manufacturers accountable. But if overturned, it could open the door for trials that could finally bring justice and compensation to those suffering from Parkinson’s after years of exposure. The stakes are high, and the outcome could have ripple effects far beyond this case.
If you or a loved one has been affected by Paraquat, now is the time to stay informed and take action. Legal options are still available, but deadlines are approaching. Don’t wait—reach out to a Paraquat lawsuit lawyer today to learn what steps you can take.
The Link Between Paraquat and Parkinson’s Disease
Scientists have been raising red flags about paraquat for a while now. A 2011 study found that people exposed to the herbicide had a significantly higher risk of developing Parkinson’s disease. In fact, some studies suggest that people exposed to Paraquat are up to 2.5 times more likely to develop Parkinson’s than those who haven’t been exposed. This has led to increased scrutiny from health officials, scientists, and lawmakers, many of whom are now pushing for stricter regulations—or an outright ban—on the herbicide in the United States.
More recent research only strengthened this connection. A 2024 study confirmed that long-term exposure to paraquat can increase the likelihood of neurological damage, fueling concerns that the chemical may be far more dangerous than originally believed.
Even with all this proof, Paraquat remains legal in the U.S., even though over 70 other countries have banned it due to health risks. This has led to growing frustration among scientists, lawmakers, and those directly affected by the herbicide.
The Fight Against Paraquat Manufacturers
As studies showed a connection between paraquat and Parkinson’s, Syngenta, Chevron, and other manufacturers faced a flood of lawsuits from agricultural workers. Farmers, farm workers, and others who developed Parkinson's disease after coming in contact with the weed killer claim these companies didn’t warn them about the dangers. The cases have been grouped into a paraquat multidistrict litigation (MDL), with more than 5,800 claims now in the works.
But the court battle has been tough. In late 2024, a federal judge excluded testimony from a key expert witness for the plaintiffs, creating a major roadblock for those trying to prove their case. This decision has made it harder for victims to establish a clear legal link between paraquat and their diagnoses, despite the growing body of scientific evidence.
Regulatory and Political Pressure
The paraquat debate isn't just a courtroom battle—it's turning into a political hot potato. In late 2024, nearly 50 U.S. lawmakers pressed the Environmental Protection Agency (EPA) to outlaw paraquat, pointing to serious worries about its health dangers. This push is part of broader pesticide regulation efforts, as regulatory bodies like the California Department of Pesticide Regulation reevaluate pesticides based on new findings regarding their risks to human health and the environment. The EPA hasn’t made a call yet, but the push for tougher rules or a total ban is growing stronger.
Paraquat vs. Other Pesticides: What Makes It So Dangerous?
Paraquat has been a popular weed killer for years, but it's way riskier than other herbicides. Most pesticides can be dangerous, but Paraquat is on another level—it's so toxic that ingesting even a tiny bit can kill you. Other weed killers break down over time, but Paraquat sticks around in the environment. Scientists have found strong connections between Paraquat and Parkinson's disease, which makes it one of the most debated chemicals still used today.
How Paraquat Stacks Up Against Other Common Pesticides
Not every weed killer poses the same risk. Many pesticides raise health concerns, but Paraquat stands out as dangerous. People have argued about the possible long-term effects of some herbicides, but Paraquat is different—it's poisonous when you're exposed to it and has a strong connection to Parkinson's disease. To understand how dangerous it is, it helps to look at Paraquat compared to other common pesticides.
- Glyphosate (Roundup): Lawsuits have focused on glyphosate due to its possible cancer risks. However, it has a much lower toxicity to humans than Paraquat. People still debate the long-term effects of glyphosate. In contrast, Paraquat’s dangers—ranging from poisoning to organ failure—are well-documented.
- Atrazine: This herbicide, commonly used in corn farming, has raised concerns about hormone disruption and water contamination. However, it doesn’t pose the same immediate risk to human health as Paraquat, nor has it been strongly linked to Parkinson’s.
- 2,4-D: You can find this in weed killers for farms and homes. People have looked at 2,4-D because it might cause cancer. But it's still not as poisonous or harmful to the brain as Paraquat.
Why Paraquat Is So Dangerous
Many weed killers pose health risks, but Paraquat stands out as one of the most poisonous chemicals still used today. Even a tiny amount can kill if swallowed, and prolonged contact has a strong link to severe brain disorders like Parkinson's disease. Here's why experts consider this weed killer one of the most risky options available.
- Highly Toxic to Humans: Many pesticides target plants but don't pose big risks to people. Paraquat stands out—it has deadly effects on humans. Even touching it or breathing it in can cause major health problems, and swallowing it by accident often kills.
- Strongly Linked to Parkinson’s Disease: Lots of research shows that being around Paraquat for a long time increases your chances of getting Parkinson's, a progressive and debilitating neurological disorder.
- Banned in Over 70 Countries: Nations across the European Union, China, and Brazil have banned Paraquat due to its extreme dangers. Yet, in the U.S., it remains widely used, despite mounting pressure from health experts and advocacy groups.
- Lingers in the Environment: Paraquat doesn't break down like some other pesticides. It stays in the soil and water for extended periods. This increases exposure risks for farmworkers, people living nearby, and even consumers.
The Fight to Ban Paraquat in the U.S.
New studies revealing Paraquat's dangers are leading to increased calls for a U.S. ban. Politicians, researchers, and health experts claim current rules fall short. The Environmental Protection Agency (EPA) has safety rules in place such as special training for handlers, but critics argue these do little to shield those at highest risk.
Not all herbicides carry the same level of danger. While many pesticides come with health concerns, Paraquat is in a category of its own. Some weed killers have been debated for their potential long-term effects, but Paraquat is different—it’s highly toxic upon exposure and has been strongly linked to Parkinson’s disease. To see just how hazardous it is, it’s useful to compare Paraquat to other widely used pesticides.
The Recent Court Ruling and What It Means for the Paraquat Lawsuits
As the legal battle over Paraquat continues, a recent court ruling has created a major setback for many of the people suing over its connection to Parkinson’s disease. A federal judge dismissed several cases in late 2024, siding with the argument that federal law protects Paraquat manufacturers from certain legal claims. This decision could make it much harder for victims to hold companies like Syngenta and Chevron accountable.
The problem boils down to federal preemption—a legal concept that says when a federal agency, like the Environmental Protection Agency (EPA), has given the green light to something, lawsuits under state law might not hold up. Here, because the EPA approved Paraquat's warning labels, the judge decided that some failure-to-warn claims shouldn't go ahead.
People who got Parkinson's after long-term exposure find this decision upsetting. It suggests that companies might avoid responsibility simply because they followed federal guidelines, even if there’s growing evidence that their product is harmful. If this ruling stands, it could set a dangerous precedent for other lawsuits involving toxic chemicals, making it harder for victims to get justice.
However, the battle isn't finished. The plaintiffs are challenging the decision claiming the judge misunderstood the law and shielded manufacturers from responsibility. A successful appeal could reinstate the dismissed cases and give victims another chance to seek justice.With bellwether trials on the horizon, this appeal could play a big role in shaping the future of the Paraquat litigation—and determining whether those affected will finally have their day in court.
What’s Next for the Paraquat Litigation?
The battle over Paraquat shows no signs of slowing down. Thousands of lawsuits remain active, and important court decisions loom on the horizon. The next few months could prove crucial for those looking to get justice.
Right now, one of the biggest questions is how the appeals court will handle the recent case dismissals. If the court overturns the decision, more plaintiffs will have the chance to prove their claims in court. If it upholds the ruling, some cases might be permanently blocked, though the larger lawsuit against Paraquat manufacturers will continue.
At the same time, the initial bellwether trials are approaching. These early test cases provide both parties with insight into how juries might react to the evidence. If plaintiffs score big wins, it could nudge Syngenta, Chevron, and other companies towards a settlement. But if the defense comes out ahead, it might make it harder for future cases to succeed.
Beyond the courtroom, there's growing pressure to tighten regulations. Politicians and advocacy groups are pushing for stronger controls—or even a complete ban—on Paraquat. If this happens, it could further highlight the dangers linked to the herbicide and boost the legal claims against its makers.
Is the U.S. Finally Moving to Ban Paraquat?
The fight to ban Paraquat in the U.S. is gaining steam. More than 70 countries, including China and the entire European Union, have already outlawed the herbicide due to its serious health risks—yet it’s still widely used here. With mounting evidence linking Paraquat to Parkinson’s disease, lawmakers, scientists, and advocacy groups are turning up the pressure to get it off the market.
Lawmakers and Advocates Are Speaking Up
Towards the end of 2024, nearly 50 U.S. lawmakers urged the Environmental Protection Agency (EPA) to stop the use of Paraquat, mentioning serious health risks for farmworkers and rural areas. Organizations such as the Environmental Working Group (EWG) and the Michael J. Fox Foundation have also been calling for action. They highlight that Paraquat exposure doesn't just threaten those who use it—wind can carry it and water can become contaminated putting people living nearby at risk too.
What’s the EPA Doing About Paraquat?
So far, not much. The EPA reviewed Paraquat in 2021 and decided to keep it on the market, adding a few extra safety measures like requiring closed-system packaging. But critics say this doesn't go far enough. As more lawsuits stack up and new studies back up the risks, the agency faces growing pressure to take tougher steps.
Will the U.S. Finally Ban Paraquat?
It’s hard to say. While the movement to outlaw Paraquat is growing, there’s still no official decision. But with legal battles intensifying and public awareness increasing, it feels like change could be on the horizon. If the U.S. does move to ban it, it could strengthen legal claims and make it easier for those affected to seek justice. Until then, the fight continues.
