Paraquat Lawsuit Settlement Amounts

Our lawyers are handling Paraquat lawsuits in all 50 states.  This page is about projected Paraquat settlement payouts for a viable Paraquat lawsuit.

People who have developed Parkinson’s disease from Paraquat want to better understand the range of settlement amounts they can expect in their Paraquat lawsuit.

It is early in the Paraquat litigation. Settlement compensation payouts are still speculative. But we can look at other similar injuries to get a settlement range if plaintiffs’ lawyers are successful, as expected, in this litigation.

The expected Paraquat settlement amounts will fluctuate as the litigation progresses. Our lawyers will continue to update this page with revised payout projections.  The last update was on September 30, 2022.

2022 Paraquat Lawsuit Update

Here are the developments in the still-growing Paraquat lawsuit in 2022:

  • November 7, 2022: Over the last two weeks nearly 100 new Paraquat Parkinson’s disease lawsuits have been transferred into the MDL. This is a continuation of the flood of new Paraquat lawsuits that we have seen over the last six months. In the meantime, both sides have filed responses to the recently issued report and recommendation of the Special Master regarding certain discovery disputes. The final briefing on that is due this week.
  • September 30, 2022: After the EPA granted interim approval status to Paraquat back in August 2021, allowing the herbicide to remain available pending a further safety review, a non-profit group in California took the agency to court to challenge the validity of that decision. This week, the EPA responded by requesting the Court to grant a voluntary remand to permit the EPA to reconsider the risk-benefit analysis that led to the prior approval decision. If granted, this request could eventually result in a decision by the EPA not to grant interim approval to Paraquat on the grounds that it is unreasonably hazardous.  Does this have huge Paraquat lawsuit implications?  Of course it does.
  • September 15, 2022: Since the start of 2022, Paraquat has been the fastest-growing mass tort MDL. Over the last monthly period (8/15/22 to 9/15/22) the number of pending Paraquat lawsuits in the Paraquat MDL went from 1,702 to 1,925. That’s an increase of 222 cases, but around 15 cases were either remanded back to state court or dismissed so the actual number of newly filed Paraquat Parkinson’s disease cases is even higher. Under the rules of the Paraquat MDL, new cases can be filed directly in the MDL in the Southern District of Illinois using the master pleading forms. This makes it hard to track where the new cases are coming from geographically. But the biggest numbers appear to be from California. The explosive growth of the Paraquat litigation recently forced the MDL class action judge to push back the bellwether trial dates and expand the discovery pool.
  • September 5, 2022: The Paraquat MDL Judge has selected a group of 20 additional cases from the MDL for limited fact discovery.   The list was randomly generated out of more than 1,700 currently pending cases.  This is a good development because it will help the defendants’ attorneys better understand how strong these claims are. This will be helpful when the lawyers sit down to negotiate settlement compensation payouts.  The judge’s order requires that depositions of the plaintiffs in each of these cases must be concluded within 60 days and a report summarizing the plaintiff’s testimony must be provided to the Court. Meanwhile, the recent flood of new incoming Paraquat cases continues. Over the last 2 weeks, around 200 new Paraquat plaintiffs have been added to the MDL. The rising number of cases was cited by the MDL Judge as one of the reasons for the order requiring additional plaintiff depositions.
  • August 25, 2022:  Unfortunately, we lost our trial date this year.  The opening bellwether test trial in the Paraquat MDL had been set for November 2022.   The second Paraquat trial was set for March 2023. The good thing about having trial dates is it places pressure on the defendants to settle or face a jury.  The hope was these trial dates would force the defendants to offer reasonable settlement compensation to victims. Yesterday, MDL Judge Nancy Rosenstengel issued an Order pushing the first trial date back nine months to July 2023.  Judge Rosenstengel made this decision after reviewing the status of discovery in the MDL and consulting with the Special Master.
  • August 16, 2022:  Over the last month 255 new Paraquat cases were added to the MDL class action. So the Paraquat class action lawsuit is still growing.   There are now 1,703 Paraquat lawsuits pending in the MDL.
  • July 20, 2022:   The Paraquat MDL now has 1,148 plaintiffs as of July 15, 2022.
  • July 4th, 2022: The Paraquat class action lawsuit has been adding about 130 new plaintiffs each month to the MDL for the last year. During the last 30 days, 142 new Paraquat lawsuits were transferred into the federal class action. This brings the total number of pending cases up to 1,292. This number is right behind the 168 new cases that got transferred into the Paraquat MDL last month. The steady pace of new Paraquat lawsuits over the last year is very different from what we have seen in other mass tort MDL class actions where the number of new lawsuits fluctuates up and down drastically from month to month.  The question continues to be whether Syngenta and Chevron intend to offer fair Paraquat settlement amounts or whether they want to roll the dice and let a jury decide whether a compensation payout is appropriate.  The bet here is they will look to settle most Paraquat lawsuits before taking a verdict. We will see.
  • June 9, 2022:  The push to the first Paraquat lawsuit trial moves forward.  The Paraquat MDL judge issued a Second Amended Discovery Schedule that provides a short, limited extension of the original discovery deadlines established for the six bellwether trial cases. Under the discovery order, the parties will have until July 25, 2022, to complete fact discovery and medical examinations. This extension of the original deadline became necessary after the number of fact witnesses made the completion of discovery more challenging.  The short length of the extension, however, should ensure that we remain on schedule for the opening bellwether trials.
  • May 16, 2022: The first half of May shows record numbers of new Paraquat lawsuits being filed and added to the Paraquat MDL class action. Fifty-seven new Paraquat Parkinson’s disease cases were filed and transferred into the MDL during the first week of May. This is the highest weekly total to date. The second week of May saw another 35 new Paraquat lawsuits added to the MDL, making it the second-highest volume week.  Overall, there are over 1,150 Paraquat plaintiffs in the Paraquat class action lawsuit.  These Parkinson’s disease lawsuits have been consolidated from around the country before one federal judge in Illinois.
  • May 11, 2022: Maybe the best thing to happen in the Paraquat class action lawsuit occurred in another piece of mass tort litigation. Bayer has been pursuing an appeal to the U.S. Supreme Court arguing that the Roundup lawsuits are preempted by the Federal Insecticide, Fungicide, and Rodenticide Act (“FIFRA”).  The premise of the appeal is that if the EPA is allowing these pesticides to remain on the market, the federal law preempts any state law injury or wrongful death claims.  The Supreme Court sought the Biden administration’s position on whether it should hear the appeal.  The Biden administration filed a brief in the case arguing that FIFRA should not be interpreted to preempt Roundup product liability claims under state law. The appeal was always a long shot for Bayer. But Bayer had been using preemption as a sword in settlement negotiations and you can bet the Paraquat defendants would do the same.  If the Supreme Court rejects Bayer’s FIFRA preemption argument as it is now expected (why would they ask if the answer was not of consequence?), it will effectively prevent Syngenta and Chevron from making the same preemption argument in the Paraquat lawsuit.
  • May 4, 2022:  The Paraquat MDL judge recently identified a group of six cases for the initial Paraquat Parkinson’s disease bellwether trials.  So these cases are moving quickly toward the first trial in November 2022.  The game plan is to take 16 sample Paraquat lawsuits out of the nearly 1000 Parkinson’s disease lawsuits that have been filed. After some limited fact discovery in these cases, Paraquat attorneys on both sides gave the MDL judge a preference list, ranking the 16 in terms of which case they most wanted to try first. Plaintiffs’ lawyers want the best facts for victims and defense attorneys to want the worst.  Based on these rankings, the judge winnowed the list down to six Paraquat lawsuits. We still don’t know which lawsuit will go first. But full discovery will now be conducted in these six potential “first Paraquat lawsuit” cases.
  • April 19, 2022:  There are now 982 Paraquat lawsuits in the MDL class action.  All allege Parkinson’s disease was caused by their Paraquat exposure.
  • April 12, 2022: The judge in the Paraquat MDL, Hon. Nancy Rosenstengel held the Paraquat class action lawsuit regular monthly status conference on April 1, 2022.  Since then, Paraquat lawyers have filed 44 more Paraquat lawsuits in just 12 days.  I don’t remember this many Paraquat lawsuits being filed in such a short span. It could just be lawyers holding back lawsuits and filing them all at once. This can lead to peaks and valleys of suits.  But there is no question that lawsuits are continuing to be filed.
  • April 1, 2022:  The status conference is today. Always of interest is the current size of the litigation and how many new cases were added to the Paraquat MDL class action lawsuit over the last month. Judge Rosenstengel may also dig deeper into the details regarding the upcoming bellwether trial selection process.
  • April 8, 2022: Paraquat has been banned in Fuji.

More Paraquat News Updates

  • March 17, 2022: 16 initial bellwether cases have been identified. Eight of the cases were selected by the plaintiffs, and the other 8 were picked by the defendants. Fact discovery in these 16 cases will conclude at the end of the month and the MDL Judge has given the parties a deadline of April 8 for submitting their “rankings” in order of preference of which cases should be scheduled for trial.
  • As of March 1, 2022, there are 688 Paraquat Parkinson’s disease lawsuits filed in the MDL class action.  An estimated 75 Paraquat suits are pending in state court.
  • On February 16, 2022, the Paraquat class action judge ruled on several motions to dismiss certain claims asserted by the plaintiffs in the Paraquat lawsuit. Judge Rosenstengel granted the motion to dismiss the plaintiffs’ claims for public nuisance and violations of Minnesota consumer protection statutes.   Plaintiff’s Paraquat attorneys do not want any claims dismissed.  Still, these were not significant counts in the lawsuits.  But I am burying the lede. The ruling leaves the remainder of the claims in the Paraquat litigation fully intact.  That clears a major obstacle for Parkinson’s disease victims, which sets the stage for Paraquat MDL to move forward into the bellwether trials in November 2022. Our lawyers hope that reasonable settlement payouts for victims will come before that first Paraquat lawsuit goes to trial.
  • On February 8, 2022, the good guys got a win in the Paraquat class action in a discovery battle yesterday. The defense lawyers were asserting the attorney-client privilege to block the discovery of certain deposition transcripts of Syngenta corporate witnesses taken in a prior paraquat lawsuit in Illinois state court.  How that would be attorney-client privilege is truly anyone’s guess.  The MDL judge rejected this argument and ordered the defendants to produce the transcripts.
  • On February 1, 2022, a dozen new Paraquat lawsuits were filed in federal court in Illinois. The plaintiffs in these lawsuits come from all over the country and allege that their exposure to Paraquat (mostly from working on commercial farms) caused them to develop Parkinson’s disease. Most of the chronic Paraquat exposure alleged by the plaintiffs occurred decades ago. The lawsuits name both Syngenta and Chevron as defendants and assert similar causes of action based primarily on failure to warn.

Paraquat Lawsuits Picked for Trial

This month, the Paraquat MDL judge confirmed a group of 16 cases for the opening round of bellwether test trials set to begin in November. Half of the 16 cases were handpicked by the defense and the other half were selected by the plaintiffs from a larger pool of bellwether discovery cases that had been randomly selected by a computer and pushed through a short fact discovery process. Bellwether jury trials will be held in the Southern District of Illinois.

Paraquat Class Action is Growing

After a new group of cases were transferred earlier this month, the number of cases pending in the Paraquat MDL-3004 is now up to 982 (as of March 16, 2022).

Motion to Dismiss

In November, the defendants filed a motion seeking to dismiss a large block of cases because they were time-barred under the applicable statute of limitations. Plaintiffs opposed this motion and the MDL judge recently set a January 10, 2022 deadline for defendants to reply in support. (Update: our lawyers reported above that plaintiffs won on the key issues. This clears a huge hurdle in getting a Paraquat lawsuit to trial in MDL 3004.)

The Plan to Push Paraquat Lawsuits to Trial

The judge in the Paraquat Parkinson’s disease class action lawsuit issued a case management order (CMO No. 12) that sets the game plan to select the lawsuits that will be the first to go to trial in this litigation.  The plan is to pick out sixteen Paraquat lawsuits.  Each side gets to pick half of the cases, subject to eligibility requirements set by the MDL judge.

Then, the lawyers start working up these lawsuits for trial.  That involves the discovery process, the fact-finding mission attorneys go to before trial.

This all pushes towards a trial date in July 2023.  Does this feel like a long time from now?  If you have Parkinson’s disease and you believe Paraquat caused your Parkinson’s, it seems a long way from a settlement and the justice you deserve.  It is not fair.  Our system moves slowly.

Future Paraquat Settlements

But the hope is that the defendants in these lawsuits realize that a Paraquat lawsuit will be hard for them to win.  If they realize this – and who knows if they do – you might see settlement compensation offered to victims before these lawsuits get to trial.

That is the hope.  Our lawyers – and many other Paraquat attorneys –  believe these are strong cases for plaintiffs that will yield large verdicts if they go to trial. But we will see how it plays out.

Paraquat Lawsuit

Hundreds of farmworkers and people who worked near oil tanks and railroads have filed lawsuits alleging that occupational exposure to the industrial herbicide paraquat (grameoxone) caused or contributed to cause Plaintiff’s development of Parkinson’s disease.

There are now over 1,700 Paraquat lawsuits. A Parkinson’s disease class action MDL has already been established to accommodate them. In this post, we will look at how much a Paraquat lawsuit might end up being worth by comparing them to settlements in prior mass product cases involving similar claims and in prior tort lawsuits in which the plaintiff developed Parkinson’s.

About the Paraquat Lawsuits

Paraquat is an industrial-strength herbicide that has been around since the 1960s. It is used to control of weeds and grasses in agricultural areas. It is also used as a defoliant, removing leaves from trees and plants.  Some farmers will use Paraquat as a desiccant, too, to keep the crops dry and stable.  Chevron started selling Paraquat in the U.S. in 1964.

This chemical is highly toxic.  A teaspoon will kill you. This has led most European countries to ban it outright. In the United States, however, Paraquat is not banned and is widely utilized by large commercial farmers.

Evidence has emerged that prolonged Paraquat exposure can lead to early-onset Parkinson’s disease. Studies have found that agricultural workers who are exposed to Paraquat over long periods have a significantly higher rate of developing Parkinson’s disease. People who live near farms where Paraquat is applied also showed increased rates of Parkinson’s disease.

Paraquat is manufactured by Syngenta, a Swiss agrochemical company. There is evidence indicating that Syngenta was aware of the causal link between paraquat and Parkinson’s for years but deliberately concealed it. Now farm workers exposed to Paraquat and subsequently diagnosed with Parkinson’s are filing product liability lawsuits against Syngenta and its U.S. distributors.

Hundreds of paraquat Parkinson’s lawsuits have been filed and a new paraquat MDL (Paraquat Prod. Liab. Lit., MDL 3004) has been created in the Southern District of Illinois for consolidated handling of the paraquat claims. The Paraquat lawsuit is still in its early stages and is expected to grow rapidly as hundreds and thousands of additional cases get filed.

Paraquat Litigation Should Result in a “Global Settlement”

At this early phase of the Paraquat Parkinson’s disease litigation, it is impossible to know how much Paraquat lawsuit settlements might be worth. Because an MDL has already been created for the Paraquat claims, our Paraquat lawyers expect this litigation to follow a familiar course in other class action lawsuits we have seen.

The Parkinson’s Disease Paraquat exposure MDL oversees a consolidated fact discovery process. This will focus on the scientific evidence for both sides. During this phase, newly filed paraquat cases will be added to the MDL.

At the end of the consolidated civil discovery phase, the MDL judge will work with lawyers for both sides to select a handful of representative cases for jury trials. In May 2022, we have narrowed that down to six potential Paraquat lawsuits.

These are known as “bellwether trials” and the results of these trials are generally used to facilitate global settlement negotiations with the defendants.

If the bellwether trials result in major victories for the plaintiffs, Syngenta may be forced to agree to pay large settlement amounts for the remaining Paraquat claims. In consolidated mass torts, this is called a “global settlement.”

What Will a Global Settlement in the Paraquat Litigation Look Like?

Here is a basic summary of how global settlements usually work in mass torts like the paraquat litigation. Let’s say Acme Co. is defending 5,000 lawsuits in an MDL by plaintiffs alleging that Acme’s widget product caused them to develop cancer.

After 18 months of discovery, four Acme widget bellwether trials are held. Acme gets a defense verdict in 1 of the bellwether trials but the other three trials result in big verdicts for the plaintiffs (an average of $2.5 million).

After losing in the 4th bellwether trial, Acme announces that it is ready to settle all the remaining widget lawsuits.  Lawyers for Acme and the plaintiffs negotiate the terms of a settlement over a few months.

Under the global settlement, Acme agrees to pay $500 million to settle the remaining 5,000 widget lawsuits. If these settlement amounts were divided evenly, it would be a gross payout of $100,000 to each plaintiff. But the settlement agreement includes a tiered system in which each plaintiff gets a settlement compensation payout according to the severity of their injuries (and other factors). Plaintiffs in the top tier get higher payouts while plaintiffs in the lower tiers get less.

This is an overly simplified example of what a global settlement in the Paraquat litigation should eventually look like and how settlement amounts would be calculated.

Key Variables for a Paraquat Lawsuit Settlement

The battlefield in the Paraquat Parkinson’s disease lawsuits is over how much the settlement compensation payouts should be.  Syngenta, Chevron, and other co-defendants are fighting to pay the smallest settlement amounts possible.

The individual Paraquat settlement amounts will depend on several things, including:

  1. how many Paraquat claims get filed and consolidated into the MDL,
  2. how strong the scientific causation evidence is for the plaintiffs between Paraquat exposure and Parkinson’s disease, and
  3. the results of the initial bellwether trials.

Estimated Paraquat Lawsuit Settlement Payout Amount

Despite all these variables that will impact the eventual payout value on Paraquat cases, our lawyers estimate a reasonable individual Parkinson’s disease settlement payouts. Our lawyers do this by looking at settlement payouts in prior mass torts and an assessment of the likelihood a jury would find the Paraquat defendants responsible.  Our attorneys also look at the settlement compensation for Parkinson’s disease in tort cases generally.

Based on these points of comparison, our Paraquat lawyers think that the likely settlement payout on Paraquat claims will be as follows:

Settlement Tier                                             Estimated Settlement

Tier I                                                               $$400,000- $1,000,000+

Tier II                                                              $150,000 – $300,000

Tier III                                                             $20,000 – $150,000

paraquat lawsuits 2022

 

Remember, we are talking about expected Paraquat settlement amounts, not trial value.  The average successful verdict in an individual Paraquat lawsuit would likely be more than $10 million with the possibility of much more in punitive damages.   Does that sound too high?  Remember, the average successful verdict in the Roundup lawsuits was well over $500 million.  In the 3M earplug lawsuit where the claim is a hearing-related injury, the average individual jury payout is well over $10 million.   Parkinson’s disease is a far more serious injury.  So an average jury compensation payout estimate of $10 million might be on the low side.

Settlement Amounts in Mass Torts Similar to Paraquat

Our first point of comparison for the estimated settlement values above is the settlement payouts in prior consolidated mass torts that have similarities to the Paraquat litigation. Our most recent example to draw from is the Roundup settlement.

In the Roundup litigation, Bayer is paying around $10 billion to settle about 100,000 cases and setting aside another $6 billion for future Roundup claims. Individual Roundup plaintiffs are getting payouts of around $100,000 to $150,000. But lawsuits in the highest tier are getting much larger settlement amounts than the average.

The Roundup litigation has some obvious similarities with Paraquat to the extent that both involve herbicide products. The alleged injuries are different because Roundup involves cancer claims whereas Paraquat plaintiffs are alleging Parkinson’s.

Between the two, cancer is probably a somewhat higher-value injury. Despite this difference, Roundup is probably the best comp for the Paraquat litigation, although our lawyers predict higher settlement amounts for Paraquat because we believe the merits of the case are even stronger in the Paraquat class action. (And, frankly, the smaller number of plaintiffs and multiple defendants grease the wheels of a larger settlement.)

Settlement Amounts in Lawsuits Involving Parkinson’s Disease

Our other comparative point for valuing the paraquat cases is the settlement value of other tort cases in which Parkinson’s disease was the plaintiff’s primary injury.

Parkinson’s is difficult to value because it is not a common injury in personal injury claims.  Camp Lejeune Parkinson’s disease lawsuits are now also being filed But there are no settlement amounts yet n that litigation.

So the next question is there a stand-in injury for Parkinson’s disease because it is an uncommon injury in tort cases that we can use as a settlement marker?  I think there is: tardive dyskinesia is similar enough that settlement amounts in those lawsuits might give us a lens to Parkinson’s disease settlement amounts.  Our lawyers have had some experience in those cases.  So let’s look at settlement amounts and jury payouts for tardive dyskinesia because it is a similar injury to Parkinson’s disease.

  • Tamaraz v Lincoln Electric (Ohio 2007) $20,500,000 Verdict: This is a rare jury payout involving a Parkinson’s disease case. Plaintiff filed a welding rod product liability lawsuit alleging he developed Parkinson’s disease from exposure to manganese in welding rods. A jury awarded $17.5 million to him and another $3 million to his wife.  This verdict underscores the high potential compensation payouts a jury might give in Parkinson’s disease case.
  • Axe v Spring Meadows (Pennsylvania 2018) $215,000 Settlement: Plaintiff was 73 years old and alleged that he developed tardive dyskinesia from medications given to him by a nursing home. Why was the settlement payout so low? I don’t know.
  • Plaintiff v Defendant (New York 2017) $1,400,000 Settlement: Plaintiff (mid-30s) develops tardive dyskinesia from antipsychotic medication used to treat her bipolar and sues the doctor who prescribed it.
  • Soref v Agresti (Florida 2017) $569,000 Verdict: female in her mid-20s with a history of drug abuse claims bipolar drugs cause her to develop tardive dyskinesia.

These cases (particularly the welding rod case) are suggestive of the type of verdict we might expect to see in Paraquat bellwether trials. These compensation awards support the settlement payout valuation estimates above.

Paraquat Lawsuits Can be Filed Decades After the Plaintiff’s Exposure

If you were recently diagnosed with Parkinson’s disease that may be related to paraquat,  you can still file a paraquat lawsuit today, even if your exposure to Paraquat occurs years or even decades ago. All states have a statute of limitations that imposes a deadline for filing a civil tort action for things such as product liability. The applicable statute of limitations period for a tort claim ranges from 1 to 7 years depending on the state.

The applicable SOL period does not begin to run, however, until the plaintiff either knew or had reason to know that they had a claim. For a paraquat lawsuit, this means that the SOL period would not begin to run until the plaintiff knew or “should have known” that they had Parkinson’s disease and that it might have been caused by exposure to paraquat.

The connection between paraquat exposure and Parkinson’s disease is something that a reasonable person would not be expected to know. This is particularly true because the companies that made and sold paraquat deliberately failed to warn about the link between paraquat and Parkinson’s. Most of the plaintiffs in the Paraquat and Parkinson’s disease litigation are bringing their claims based on exposure that occurred a very long time ago.

Link Between Paraquat and Parkinson’s Disease

Parkinson’s disease is a progressive neurodegenerative disorder of the brain that affects primarily the motor system, the part of the central nervous system that controls movement.

The characteristic symptoms of Parkinson’s disease are its “primary” motor symptoms: resting tremor; bradykinesia (slowness in voluntary movement and reflexes); rigidity; and postural instability. There is currently no cure for Parkinson’s disease. Existing treatments do not slow or stop their progression; such treatments are capable only of temporarily and partially relieving the motor symptoms. These treatments also have unwelcome side effects the longer they are used.

Paraquat is a toxic chemical that is a highly effective plant killer. Unfortunately, the same properties that make paraquat toxic to plant cells also make it highly damaging to human nerve cells and create a substantial risk to anyone who uses it.

Oxidative stress is a major factor in—if not the precipitating cause of—the degermation and death of dopaminergic neurons which is the primary pathophysiological cause of Parkinson’s disease. Paraquat is designed to injure and kill plants by creating oxidative stress, which causes or contributes to causing the degeneration and death of plant cells. Similarly, Paraquat injures and kills animals by creating oxidative stress, which causes the degeneration and death of animal cells.

The causal link between Paraquat and Parkinson’s disease is well established.  Hundreds of animal studies involving various routes of exposure have found that paraquat creates oxidative stress that results in pathophysiology consistent with that seen in human Parkinson’s disease.

Many epidemiological studies have also found an association between Paraquat exposure and Parkinson’s disease, including multiple studies finding a two- to five-fold or greater increase in the risk of Parkinson’s disease in populations with occupational exposure to paraquat compared to populations without such exposure.

You do not have to work on a farm to have a viable Paraquat lawsuit. Researchers in an article in the American Journal of Epidemiology found that exposure to Paraquat or Maneb within 1600 feet of your home causes a 75% increase in the risk of getting Parkinson’s disease.

Here are the key articles on Paraquat exposure and Parkinson’s disease with a summary of the findings:

  • Berry, C., La Vecchia, C., & Nicotera, P. (2010). Paraquat and Parkinson’s disease. Cell Death & Differentiation, 17(7), 1115-1125. This study looked at pesticides’ role in causing Parkinson’s disease. The researchers report that acute chemical exposure was “sufficient” enough to cause Parkinson’s.
  • Costello, S., et al. (2009). Parkinson’s disease and residential exposure to maneb and paraquat from agricultural applications in the central valley of California. American journal of epidemiology, 169(8), 919-926.  This study looked at whether living near pesticide-using farms was associated with Parkinson’s. The researchers found that living within 500 feet of farms that used paraquat and maneb increased one’s Parkinson’s risk by 75 percent. They also found that people younger than 60 were at significantly higher risk. The researchers concluded that their findings show that exposure to paraquat and maneb, whether alone or combined, significantly increased the Parkinson’s risk.
  • Di Monte, D.A. (2003). The environment and Parkinson’s disease: is the nigrostriatal system preferentially targeted by neurotoxins? The Lancet Neurology, 2(9), 531-538. This report concluded that a multidisciplinary approach to Parkinson’s etiology would help determine whether environmental exposure may cause the disease.
  • Firestone, J. A., et al. (2005). Pesticides and Risk of Parkinson’s Disease: a population-based case-control study. Archives of Neurology, 62(1), 91-95.  This study looked at whether pesticides were associated with Parkinson’s. The researchers interviewed 250 Parkinson’s patients and 388 non-Parkinson’s patients. They assessed their self-reported pesticide exposures. The researchers also categorized the patients by occupation. They found that pesticide workers were more likely to develop Parkinson’s compared to crop, animal and crop, and dairy farmers. The researchers concluded that their findings were consistent with other studies that found an association between pesticides and Parkinson’s.
  • Mandel, J. S., Adami, H. O., & Cole, P. (2012). Paraquat and Parkinson’s disease: an overview of the epidemiology and a review of two recent studies. Regulatory Toxicology and Pharmacology, 62(2), 385-392. The report evaluated two studies that evaluated pesticide exposure’s association with Parkinson’s. The researchers found that the researchers created inadequately designed studies that examined very few exposed patients. They also reported that their results were inconsistent. The researchers concluded that these two studies fail to prove an association between pesticides and Parkinson’s. They also concluded that more rigorous studies were needed for confirmation.
  • McCormack, A. L., et al. (2002). Environmental risk factors and Parkinson’s disease: selective degeneration of nigral dopaminergic neurons caused by the herbicide paraquat. Neurobiology of Disease, 10(2), 119-127.  This study looked at whether Paraquat exposure caused Parkinson’s disease symptoms in mice. The researchers injected mice with the herbicide. They found that this caused dopaminergic neuron death, a Parkinson’s disease symptom. The researchers concluded that the findings show that Paraquat neurotoxicity caused a prominent physiological response to Parkinson’s.
  • Stephenson, J. (2000). Exposure to home pesticides linked to Parkinson’s disease. JAMA, 283(23), 3055-3056. This article reported on the association between home or garden exposures to pesticides and Parkinson’s.
  • Stykel, M.G., et al. (2018). Nitration of microtubules blocks axonal mitochondrial transport in a human pluripotent stem cell model of Parkinson’s disease. The FASEB Journal, 32(10), 5350-5364. This study looked at mechanisms showing that pesticide exposure disrupted cells in a manner that mimicked Parkinson’s-associated mutations. The researchers concluded that their results were the first to demonstrate a gene that triggered mitochondrial transport deficits during pesticide exposure.  Here is the money quote from one of the authors: “People exposed to these chemicals are at about a 250-percent higher risk of developing Parkinson’s disease than the rest of the population.”  So most people who have Parkinson’s disease from Paraquat would not have had Parkinson’s disease without Paraquat exposure.
  • Tanner, C. M., et al. (2011). Rotenone, Paraquat, and Parkinson’s disease. Environmental health perspectives, 119(6), 866-872. This study looked at whether pesticides that caused oxidative stress or mitochondrial dysfunction were associated with Parkinson’s in humans. The researchers found that paraquat and rotenone were associated with Parkinson’s.

This study looked at a novel model that determined environmental factors and genetic susceptibility that formed idiopathic Parkinson’s underlying molecular basis. The researchers found that some pesticides and metals caused conformational alpha-synuclein changes and accelerated the alpha-synuclein fibrils rate.

Journal of Toxicology and Environmental Health, Part B, 22(5-6), 172-202. This systematic review looked at literature and meta-analysis involving paraquat’s exposure to Parkinson’s. The researchers found that the current data suggest a positive association between Paraquat exposure and Parkinson’s. However, they concluded that the evidence was insufficient to indicate a causal association. The researchers reported that better-designed studies were needed.

In addition to causing Parkinson’s disease, new evidence has also shown that chronic exposure to Paraquat can also cause permanent damage to the kidneys. The kidney is the main organ responsible for Paraquat excretion and Paraquat is known to be highly nephrotoxic.

Dermal exposure to Paraquat has revealed inflammatory cell infiltration, tubular necrosis, and diffuse interstitial fibrosis.  Paraquat exposure causes toxic chemical reactions to occur in the kidneys, and long-term effects, including kidney failure, are possible.

Paraquat lawyers have not focused on these cases because there are so many more Parkinson’s disease lawsuits.  But these injuries are very real to victims.

Paraquat Defense Lawyers Lost Arrow in Quiver

Paraquat exposure to Parkinson’s disease lawsuits is considered by mass tort lawyers to be strong cases.  Victims’ attorneys believe proving the defendant’s responsibility will be as easy as any major class action lawsuit in 2022.  That is why Paraquat lawyers are spending a fortune online trying to market for Paraquat lawsuits.

The last time a Paraquat lawsuit was set for trial, the defendants quickly settled those lawsuits.  The speculation is the settlement compensation payouts in those claims were very high.  That fueled many Paraquat lawyers to jump into this Parkinson’s disease pesticide exposure cases.  So I expect that any solid Paraquat lawsuit heading towards trial will be settled by the defendants.

The defendants’ only hope in my mind of getting out of this litigation without paying huge jury payouts of settlement compensation is by these lawsuits never seeing a jury.  The path to that outcome was for Bayer to win its appeal in the Roundup litigation.

Bayer argued Roundup lawsuits should be preempted by the Federal Insecticide, Fungicide, and Rodenticide Act.  Bayer lost.  This verdict makes the Paraquat class action lawsuit that much stronger.

FAQs: Paraquat Lawsuit Payouts

What are the expected settlement amounts for Paraquat lawsuits?

Paraquat lawsuits in the highest settlement tier could have a settlement payout value between $400,000 and $1,000,000. Cases with lower settlement tiers will have lower values.  Our lawyers have high expectations for the settlement value of Parkinson’s Paraquat lawsuits.

Keep in mind speculation about settlement compensation payouts or when these Paraquat lawsuits might settle is purely speculative.  You might also be disheartened by how fluid our settlement projections are.   Our projections rise and fall day to day. But there is one thread that runs through all our Paraquat lawsuit settlement amount projections: our lawyers think these are great cases and will ultimately resolve for good settlements.

When will the Paraquat lawsuits settle?

A global settlement in the paraquat litigation is not expected until early 2023 at the earliest.   

What is the deadline for filing a paraquat lawsuit?

Most Paraquat lawsuits are filed years or decades after the plaintiff was actually exposed to Paraquat.

So how do Paraquat plaintiffs get around the statute of limitations?  Here is how it works.

Every Paraquat lawsuit alleges that this weed killer was manufactured and distributed by the defendants and did not provide a warning label so people using it knew of the risk of latent neurological damage, most notably, Parkinson’s disease.

So when Plaintiffs were diagnosed with Parkinson’s, they could not connect the dots between Paraquat and Parkinson’s disease.  Courts often apply the discovery rule in these cases. So the clock on the deadline to sue cannot start until the plaintiff knows or has reason to know of the connection between
their exposure to Paraquat and his or her neurological disease.

So what is your deadline to file a Paraquat lawsuit?  Calculating the exact deadline for filing your claim can be complicated and you should consult with a lawyer.
