Paraquat Papers

Print Email Share Tweet

Multiple lawsuits are pending in the United States alleging the weedkilling chemical paraquat causes Parkinson’s disease, and the first case to go to trial over the allegations against Syngenta over paraquat and Parkinson’s was originally scheduled for April 12 but was rescheduled for May 10 in St. Clair County Circuit Court in Illinois and then was delayed again until June 1 and then was called off on May 28.  The parties reportedly settled the case.

A notice of settlement was filed June 18, 2021 for several paraquat cases. See this document.

There are dozens of lawsuits pending against Syngenta alleging the company’s paraquat products cause Parkinson’s Disease. The Hoffman case also names Chevron Phillips Chemical Co. and Growmark Inc. as defendants. Chevron distributed and sold Gramoxone paraquat product in the United States in an agreement with a Syngenta predecessor called Imperial Chemical Industries (ICI), which introduced paraquat-based Gramoxone in 1962. Under a license agreement, Chevron had the right to to manufacture, use, and sell paraquat formulations in the U.S.

Lawyers around the United States are advertising for plaintiffs, seeking to draw in thousands of people who’ve been exposed to paraquat and now suffer from Parkinson’s.

Some of  the most recently filed cases were brought in federal courts in California and Illinois. Among those cases are Rakoczy V. Syngenta,  Durbin V. Syngenta and Kearns V. Syngenta.

On April 7, 2021, the Fears Nachawati Texas-based law firm filed a motion with the U.S. Judicial Panel on Multidistrict Litigation in Washington, D.C., asking that pending paraquat lawsuits be consolidated for pretrial proceedings in the Northern District of California, the same federal court where Roundup litigation was consolidated. The case with the judicial panel is MDL No. 3004. The panel hearing on the matter was May 27 and on June 7, the panel approved the formation of the paraquat multidistrict litigation, assigning it to Judge  Nancy J. Rosenstengel in the Southern District of Illinois.

Additionally, a class action lawsuit was filed in federal court in Iowa on May 3. The suit seeks “equitable relief in the form of medical monitoring, including, but not limited to, the costs of diagnostic testing” for farmers and others exposed to paraquat who are allegedly at “increased risk” for Parkinson’s, according to the legal filing.

Several scientific studies have linked paraquat to Parkinson’s, including a large study of U.S. farmers jointly overseen by multiple U.S. government agencies.  Farmers use paraquat in the production of many crops, including corn, soy and cotton. The Agricultural Health Study (AHS) said it found that “exposure to agricultural pesticides may increase a person’s risk of developing Parkinson’s disease.” In 2011, AHS researchers reported that “participants who used paraquat or rotenone were twice as likely to develop Parkinson’s disease as people who didn’t use these chemicals.”

A more recent paper from AHS researchers stated that “Extensive literature suggests an association between general pesticide use and Parkinson’s disease (PD). However, with few exceptions, little is known about associations between specific pesticides and PD.”

Parkinson’s is an incurable progressive nervous system disorder that limits a person’s ability to control movement, causing tremors, loss of balance and eventually often leaving victims bedridden and/or bound to a wheelchair. The disease is not necessarily fatal but typically becomes severely debilitating.

Dutch neurologist Bastiaan Bloem, who recently authored a book about Parkinson’s, blames widespread exposure to herbicides such as paraquat, along with other toxic chemicals used in agriculture and manufacturing, for the spread of the disease.

Acutely Toxic 

Along with fears about links between paraquat and Parkinson’s, paraquat is also known to be an extremely acutely toxic chemical that can quickly kill people who ingest very small amounts. In Europe, the sale of paraquat has been banned since 2007, but in the United States the pesticide is sold as a “Restricted Use Pesticide” due to “acute toxicity.”

As part of discovery in the Parkinson’s litigation, lawyers have obtained internal records from Syngenta and its predecessor corporate entities dating back to the 1960s. Many of these documents are sealed, but some have started to come to light.

Those unsealed discovery documents, which include copies of letters, minutes of meetings, study summaries, and emails, are being made available on this page.

Most of the documents unsealed to date deal with corporate discussions about how to keep paraquat herbicides on the market despite its deadliness, through measures designed to reduce accidental poisonings. Specifically, many of the documents detail an internal corporate struggle over the addition of an emetic, a vomit-inducing agent, to paraquat products.  Today, all Syngenta paraquat-containing products include an emetic called “PP796.”  Liquid paraquat-containing formulations from Syngenta also include a stenching agent to produce a foul odor, and a blue dye to differentiate the dark-colored herbicide from tea or cola or other beverages.

EPA Review 

Paraquat is currently undergoing the EPA’s registration review process, and on Oct. 23, 2020, the agency  released a proposed interim decision (PID) for paraquat, which proposes mitigation measures to reduce human health and ecological risks identified in the agency’s 2019 draft human health and ecological risk assessments.

The EPA said that through collaboration with the National Toxicology Program at the National Institute of Environmental Health Sciences, the agency completed a “thorough review” of the scientific information on paraquat and Parkinson’s Disease and concluded that the weight of evidence was insufficient to link paraquat to Parkinson’s disease. The agency published this “Systematic Review of the Literature to Evaluate the Relationship between Paraquat Dichloride Exposure and Parkinson’s Disease.”

USRTK will add documents to this page as they become available.

Consolidation approved for lawsuits against Syngenta and Chevron over herbicide

A U.S. judicial panel has ordered the pretrial consolidation of dozens of lawsuits against Syngenta and Chevron over allegations that paraquat weed killer, which has been used widely around the world for more than 50 years, causes Parkinson’s disease.

The U.S. Judicial Panel on Multidistrict Litigation said that “to date, 77 actions and potential tag-along actions are pending in sixteen different districts,” and they all involve “common factual issues concerning the propensity of paraquat to cause Parkinson’s Disease.” The cases will include “complex scientific and regulatory issues,” the panel said.

“Centralization will eliminate duplicative discovery; avoid inconsistent pretrial rulings; and conserve the resources of the parties, their counsel and the judiciary,” the panel stated in its order.

The panel determined the cases will be transferred to the federal court in the Southern District of Illinois and assigned to U.S. Judge Nancy Rosenstengel for handling.

Lawyer Majed Nachawati, whose firm is among those representing hundreds of plaintiffs suing Syngenta and Chevron, applauded the decision, and said the litigation is “monumentally important.” It was Nachawati’s firm that requested the MDL.

Syngenta, a Swiss company owned by a larger Chinese chemical company, developed and markets the paraquat-based Gramoxone brand, while Chevron has been a distributor of Syngenta’s paraquat products in the United States.

The formation of the paraquat multidistrict litigation (MDL) underscores the legal threat Syngenta faces in the litigation.  An MDL was also formed for the lawsuits filed against Monsanto over allegations that its Roundup weed killers cause non-Hodgkin lymphoma; ultimately tens of thousands of people sued the company for such claims and Monsanto’s owner, Bayer AG, is now facing settlement payouts of more than $10 billion.

Syngenta said in a statement that it agrees with the decision to coordinate the various federal lawsuits before one judge.

“This will help the parties and the courts proceed in a timely and efficient way,” the company said.

Chevron did not respond to a request for comment.

Used since the ’60s

Paraquat has been used in the United States since 1964 as a tool to kill broadleaf weeds and grasses. Farmers often use paraquat before planting crops or before those crops emerge. It has long been known to be extremely dangerous to anyone who ingests even a small amount, and regulators have issued warnings and placed restrictions on its use because of poisoning risks.

The body of science showing links between Parkinson’s disease and paraquat is less clear, having evolved over time. The EPA does not currently confirm a causal link to Parkinson’s disease. But many scientists say the research showing causation is robust.

Several scientific studies have linked paraquat to Parkinson’s, including a large study of U.S. farmers jointly overseen by multiple U.S. government agencies.

The Agricultural Health Study (AHS), which is backed by numerous U.S. agencies and researchers, has found that “exposure to agricultural pesticides may increase a person’s risk of developing Parkinson’s disease.” And in 2011, AHS researchers reported that participants who used paraquat or another pesticide were “twice as likely to develop Parkinson’s disease” as people who were not exposed to those chemicals.

Syngenta maintains that newer and better research, including by AHS scientists, has discounted a tie between paraquat and Parkinson’s.

In addition to the cases brought on behalf of people suffering from Parkinson’s, additionally, a class action lawsuit was filed in federal court in Iowa on May 3 by a law firm representing people who fear they may get the disease in the future.

The suit seeks “equitable relief in the form of medical monitoring, including, but not limited to, the costs of diagnostic testing” for farmers and others exposed to paraquat who are allegedly at “increased risk” for Parkinson’s, according to the legal filing.

Settlement rumors

What was supposed to be the first trial over allegations that Syngenta’s paraquat causes Parkinson’s has been delayed multiple times and the parties may be nearing a settlement, according to sources close to the case.

The trial in the case of Hoffman V. Syngenta is pending in St. Clair County Circuit Court in Illinois and has had multiple trial dates set and then cancelled, the most recent earlier this month.

The lawyer for the plaintiffs in that case had pronounced publicly that he had internal Syngenta documents that would expose the company’s alleged knowledge of connections between paraquat and Parkinson’s.

But Syngenta steadfastly has denied any such evidence exists.

“Syngenta has great sympathy for the health issues faced by the plaintiffs and others suffering from the debilitating effects of Parkinson’s disease,” the company’s statement reads.  “We care deeply about the health and well-being of farmers and are dedicated to providing them safe and effective products. There is no credible evidence that Paraquat, which has been widely used for more than 55 years, causes Parkinson’s disease.  No peer reviewed study, including the largest study which involved 38,000 farmers, has ever concluded Paraquat causes Parkinson’s disease.  The EPA and other government authorities have extensively analyzed this issue and similarly found no evidence that Paraquat causes Parkinson’s disease. The facts simply do not support the Plaintiffs’ allegations, and we intend to defend this product and our legal position vigorously in court.”

Another delay for trial set to examine allegation that Syngenta weed killer causes Parkinson’s

A highly anticipated first-ever trial pitting a group of farmers against the global agricultural giant Syngenta AG over allegations that Syngenta’s paraquat weed killer causes Parkinson’s disease has been delayed again and may not take place at all, according to sources close to the case.

The trial in the case of Hoffman V. Syngenta was scheduled to start June 1 in St. Clair County Circuit Court in Illinois before Associate Judge Kevin Hoerner. Previously it was set to begin May 10, and prior to that it had a trial date in April.

The cancellation of the June 1 trial date came amid speculation that the parties are deep into settlement talks. No new trial date has yet been set, according to a St. Clair County Circuit Court clerk.

The plaintiffs in the case developed Parkinson’s after repeated exposure to paraquat products, specifically Syngenta’s widely used Gramoxone brand. Three of the original plaintiffs in the case have died, including plaintiff Thomas Hoffman.

The trial was to be livestreamed by Courtroom View Network, and plaintiffs’ attorney Steve Tillery had vowed to unveil decades of internal corporate documents he said would show Syngenta knew its paraquat-based weed killer causes Parkinson’s disease, a disorder that impacts nerve cells in the brain and  leads in advanced cases to severe physical debilitation and often dementia and death.

Tillery would not respond to a request for comment, and a Syngenta spokesman also declined to comment.

Also named as defendants in the case are Chevron Phillips Chemical Co., formed as a joint venture between Chevron USA and Phillips 66. Chevron helped distribute Syngenta’s products in the United States. Illinois agricultural cooperative Growmark is also a defendant for its role in supplying paraquat products.

There are currently at least 20 lawsuits filed in multiple state and federal courts across the country on behalf of plaintiffs who have been diagnosed with Parkinson’s and claim Syngenta’s paraquat weed killers are to blame.

The caseload is expected to grow rapidly, and on Thursday the U.S. Judicial Panel on Multidistrict Litigation heard arguments on a motion filed by the Texas-based law firm of Fears Nachawati asking that pending paraquat lawsuits be consolidated for pretrial proceedings in the Northern District of California, the same federal court where Roundup litigation was consolidated.

Additionally, a class action lawsuit was filed in federal court in Iowa on May 3. The suit seeks “equitable relief in the form of medical monitoring, including, but not limited to, the costs of diagnostic testing” for farmers and others exposed to paraquat who are allegedly at “increased risk” for Parkinson’s, according to the legal filing.

Syngenta argues that newer and more robust research, including by AHS scientists, has discounted a tie between paraquat and Parkinson’s.

Judge shoots down Bayer’s plan to limit future Roundup legal liability, issues harsh criticism

Print Email Share Tweet

(UPDATED May 27 with Bayer statement about new plans)

The federal judge overseeing nationwide Roundup litigation on Wednesday denied Bayer’s latest attempt to limit its legal liability from future cancer claims associated with its glyphosate-based herbicides, citing numerous “glaring flaws” in a settlement proposed to apply to Roundup users who have not yet sued the company but may want to do so in the future.

Saying parts of the plan were “clearly unreasonable” and unfair to cancer sufferers who would be part of the class settlement, U.S. Judge Vince Chhabria castigated Bayer and the small group of lawyers who put the plan together in conjunction with Bayer.

He pointed out that the company has been “losing trials left and right” in claims brought by people suffering from non-Hodgkin lymphoma (NHL) who alleged exposure to Monsanto’s Roundup and other glyphosate-based herbicides were the cause.

Bayer has owned Monsanto since 2018 and has been struggling to defend the cancer claims ever since. Cancer victims have won three trials held to date, and tens of thousands of other plaintiffs have filed lawsuits alleging exposure to Monsanto’s herbicides caused them to develop NHL while Monsanto spent decades hiding the risks.

Elizabeth Cabraser, one of the lawyers who structured the settlement plan, said the proponents were “disappointed” by the ruling and “continue to believe that a multi-billion-dollar class settlement that includes free legal services and substantial compensation to claimants, NHL diagnostic assistance, research into NHL treatment, and Roundup label reform to inform users and the public on all the science regarding a Roundup/NHL link, would provide tremendous financial, health and safety benefits for class members.”

But one of the lead objectors to the plan, lawyer Majed Nachawati, said Cabraser had attempted to “create a sham settlement” that would have harmed the legal rights of “thousands of injured Americans.”

Bayer issued a statement following the judge’s order saying it would consider “the future of glyphosate-based products in the U.S. residential market,” though any changes there would “not affect the availability of glyphosate-based products in markets for professional and agricultural users.” The company said discussions about the future of residential Roundup products was part of a “five-point plan” the company would now pursue.

“The new package of measures, which combine a number of legal and commercial actions, is designed to help the company achieve a level of risk mitigation that is comparable to the previously proposed national class solution,” Bayer said.

Evidence favors plaintiffs, judge says

Judge Chhabria said in his decision that the company’s desire to set up a “science panel” to determine whether or not the herbicides actually cause cancer rather than leave that question to future juries is because of the trial losses the company has so far suffered.

The “reason Monsanto wants a science panel so badly is that the company has lost the ‘battle of the experts’ in three trials, the judge wrote in his order.  “At present, the playing field on the issue of expert testimony related to causation is slanted heavily in favor of plaintiffs.”

The ruling comes after a lengthy hearing last week held to discuss widespread opposition by personal injury attorneys across the United States to the settlement proposal. The proposed plan called for Bayer to put up roughly $2 billion for a series of actions that would help the company avoid future Roundup cancer trials.

The class action settlement would apply to people exposed to Roundup products as of Feb. 3, 2021 who have not yet sued Monsanto or retained a lawyer to do so. The settlement plan would set up a framework for addressing new claims brought by those exposed individuals who develop NHL they attribute to their Roundup exposure. It would apply to people who already have NHL but who have not yet sued the company and to people who develop NHL in the future.

The plan was structured by Bayer in coordination with a small team of plaintiffs’ lawyers who stood to be paid millions of dollars for their participation.

Proponents of the proposed class action plan told the judge it “will save lives,” and provide “speedy compensation” to people who get NHL they blame on Roundup exposure.

But opponents said the proposal actually did little for cancer patients while benefiting Bayer and the lawyers who helped develop the plan.

At the heart of the objections is the view that if approved, the class action plan could limit the due process rights of people to go to trial and seek punitive damages awards in the future if they are diagnosed with NHL after Roundup exposure, while allowing Bayer to keep selling Roundup products with no express warning of a cancer risk on the label.

The limiting of plaintiffs’ ability to seek punitive damages while not limiting Bayer’s ability to keep selling Roundup distinguishes this settlement from any similar class action, according to an opposition brief filed by the nonprofit legal group Public Justice. The plan is a “blueprint for how manufacturers can cut off victims’ rights to seek punitive damages from injuries caused by hazardous pesticides, the group said.

Another key problem with the plan, according to critics, is that everyone in the United States who meets the criteria as a potential plaintiff would automatically become part of the class and subject to its provisions if they did not actively opt out of the class within a specified time period. If people did not opt out – even if they didn’t know about the plan – they would be stripped of  the right to seek punitive damages if they ever did file a lawsuit.

“Monsanto tried to buy its own system of justice and it is wonderful that the court saw through what they were trying to do,” said lawyer Gerson Smoger, who is among the opponents.  “The settlement would’ve been a travesty for those who use Roundup.”

Separate from larger settlement

The class action plan, which is separate from an $11 billion settlement of Roundup litigation announced by Bayer last June to address already filed lawsuits, needs approval from Chhabria. The judge has been overseeing the federal multidistrict Roundup litigation involving thousands of plaintiffs from around the United States.

Bayer’s desire to find a settlement is “not surprising because the alternative to settling – continuing to lose trials left and right – is not attractive,” the judge wrote in his ruling.

“In sum, the settlement proposed by these attorneys would accomplish a lot for Monsanto,” he wrote. “It would substantially diminish the company’s settlement exposure and litigation exposure at the
back end, eliminating punitive damages and potentially increasing its chances of winning trials
on compensatory damages. It would accomplish far less for the Roundup users who have not
been diagnosed with NHL—and not nearly as much as the attorneys pushing this deal contend.”

Bayer’s new plan

Bayer said in addition to consideration of withdrawing Roundup from residential use, the company’s  plan includes the following:

  • Creation and promotion of a new website with scientific studies relevant to Roundup safety, and a request that EPA approves corresponding language on Roundup labels.
  • Exploration of the creation of an independent scientific advisory panel comprised of external scientific experts to review scientific information regarding the safety of Roundup. The results would be released publicly and added to the new website.
  • Continuation of settlement discussions and continuing appeals of the two of the three cases lost at trial. The company already exhausted appeals in the first case it lost at trial. Bayer is hoping to get a case to the U.S. Supreme Court and get a favorable ruling on its position that state-based failure-to-warn claims conflict with, and are preempted by, federal law.

Paraquat litigation grows, first trial set for May 10

Print Email Share Tweet

Six more lawsuits alleging Syngenta’s weed killing pesticide paraquat causes Parkinson’s Disease were filed last week in Pennsylvania, California and Illinois, adding to more than a dozen similar lawsuits already filed in U.S. courts.

The lawsuits all allege that exposure to paraquat,  which is banned in more than 30 countries though not in the United States, causes the incurable and progressive Parkinson’s disorder that affects nerve cells in the brain, leading in advanced cases to severe physical debilitation and often dementia and death.

Many Parkinson’s experts say the disease can be caused by a range of factors, including exposure to pesticides such as paraquat, as well as other chemicals.

The first trial set to take place in the United States is to begin on May 10 in St. Clair County Circuit Court in Illinois. Missouri lawyer Steve Tillery  is representing the plaintiffs in Hoffman V. Syngenta and said he plans to introduce evidence that includes internal company records showing Syngenta has known for decades that its product causes Parkinson’s Disease.

The defendants in the Hoffman case, as well as the other cases filed, name the Swiss-based Syngenta and Chevron USA as defendants.

Both Chevron and Syngenta deny there is a connection between the disease and the weed killer.

Chevron distributed and sold paraquat products in the United States starting with an agreement with a Syngenta predecessor called Imperial Chemical Industries (ICI), which introduced a paraquat-based herbicide called Gramoxone in 1962. Under a license agreement, Chevron had the right to manufacture, use, and sell paraquat formulations in the U.S.

Syngenta says that its paraquat products have been approved as “safe and effective” for more than 50 years and it will “vigorously” defend the lawsuits. Syngenta is owned by China National Chemical Corporation, known as ChemChina.

The complaints were filed on April 30 by a team of law firms: DiCello Levitt Gutzler, Saltz Mongeluzzi & Bendesky, P.C. and  Searcy Denney.

Mark DiCello, one of the plaintiffs’ attorneys bringing the cases, said Chevron and Syngenta have “long known they were peddling this poison,” and that the science surrounding paraquat “is conclusively on the side of the plaintiffs.”

Jeffrey Goodman, another of the plaintiffs’ attorneys helping bring the litigation said the filings so far are but the “tip of the iceberg” of what he expects to expand into a major mass tort case.

“The manufacturers of paraquat knew for decades that their product was linked to Parkinson’s disease yet chose to hide this information from regulators and the public,” Goodman said.

The newly filed cases are:

The new cases join at least 14 lawsuits filed by eight different law firms in six different federal courts across the country.

Move to consolidate U.S. paraquat litigation as cases mount against Syngenta

Print Email Share Tweet

Lawyers suing Swiss chemical company Syngenta are asking a U.S. judicial panel to consolidate more than a dozen similar lawsuits under the oversight of a federal judge in California. The move is a telling sign of the expansion of litigation that alleges the company’s weed killing products cause Parkinson’s Disease.

According to the motion, filed April 7 by the Texas-based Fears Nachawati law firm with the U.S. Judicial Panel on Multidistrict Litigation, there are currently at least 14 lawsuits filed by eight different law firms in six different federal courts across the country. The lawsuits are all filed on behalf of plaintiffs who have been diagnosed with the neurodegenerative disorder, and they allege exposure to Syngenta’s weed killers made with a chemical called paraquat for the disease. Several other cases making the same allegations are pending in state courts.

“The cases are excellent candidates for coordinated pretrial proceedings because they arise from the same poisonous toxin causing the same crippling disease resulting from the wrongful conduct of the same three defendants,” the Fears Nachawati brief in support of its motion states. “Movant expects that the number of similar cases filed in state and federal courts across the country will expand rapidly.”

The motion seeks transfer specifically to Judge Edward Chen in the U.S. District Court for the Northern District of California.

Majed Nachawati, a partner with the Fears Nachawati firm, said the firm was still investigating the size and scope of the overall litigation but believes the paraquat litigation against Syngenta “will be significant and material in nature…”

“Very soon, there is going to be litigation in dozens of federal courts across the country,” Nachawati said.

The plaintiffs’ lawyers will be seeking internal corporate documents as well as depositions of corporate officials related to the “testing, design, labeling, marketing, and safety of paraquat herbicides,” along with corporate research and evaluations of the toxicity and safety of its paraquat products.

The Miller Firm of Virginia, which helped lead the Roundup cancer litigation against Monsanto that resulted in an $11 billion settlement with Monsanto owner Bayer AG, is among the law firms joining in the paraquat litigation. The Miller firm supports the effort to consolidate the federal actions in California, where thousands of Roundup cases were also consolidated for pretrial proceedings, according to the firm’s lead attorney Mike Miller.

“We are confident that science strongly supports the causal connection between paraquat and the devastation of Parkinson’s disease,” Miller said of the motion. “The Northern District of California is well equipped to handle these cases.”

The cases against Syngenta also name Chevron Phillips Chemical Co. as a defendant. Chevron distributed and sold Gramoxone paraquat products in the United States starting with an agreement with a Syngenta predecessor called Imperial Chemical Industries (ICI), which introduced paraquat-based Gramoxone in 1962. Under a license agreement, Chevron had the right to manufacture, use, and sell paraquat formulations in the U.S.

Syngenta and Chevron have denied the allegations.

Syngenta says that its paraquat products have been approved as “safe and effective” for more than 50 years and it will “vigorously” defend the lawsuits. Syngenta is owned by China National Chemical Corporation, known as ChemChina.

Scientific studies

Parkinson’s is an incurable progressive disorder that affects nerve cells in the brain, leading in advanced cases to severe physical debilitation and often dementia. Many Parkinson’s experts say the disease can be caused by a range of factors, including exposure to pesticides such as paraquat, as well as other chemicals.

Several scientific studies have linked paraquat to Parkinson’s, including a large study of U.S. farmers jointly overseen by multiple U.S. government agencies. That 2011 research reported that people who used paraquat were twice as likely to develop Parkinson’s disease as people who did not use it.

“Numerous epidemiological and animal studies have linked paraquat to Parkinson’s disease,” said Ray Dorsey, a professor of neurology and director of the Center for Human Experimental Therapeutics at University of Rochester in New York. Dorsey is also the author of a book about prevention and treatment of Parkinson’s Disease.

“The evidence linking paraquat to Parkinson’s disease is probably the strongest of any pesticide commonly used,” he said.

Some studies have not found any clear links between paraquat and Parkinson’s and Syngenta asserts that the most recent and authoritative research does not show a connection.

Indeed, a study published in 2020 found connections between some other pesticides and Parkinson’s, but no strong evidence showing paraquat causes the disease.

Upcoming trial

One case filed in a state court is scheduled to go to trial next month. Hoffman V. Syngenta is slated for trial May 10 in St. Clair County Circuit Court in Illinois. A status conference is scheduled for the end of this month.

Missouri lawyer Steve Tillery, who is representing the plaintiffs in the Hoffman case as well as several other plaintiffs in other paraquat lawsuits, said despite Syngenta’s assertions to the contrary, he has accumulated evidence that includes internal company records showing Syngenta has known for decades that its product causes Parkinson’s Disease.

“They shouldn’t be selling this product, said Tillery. “This chemical should be off the market.”

The Monsanto Papers – Deadly Secrets, Corporate Corruption, and One Man’s Search for Justice

Print Email Share Tweet

USRTK Research Director Carey Gillam’s new book is out now and garnering glowing reviews. Here is a brief description of the book from publisher Island Press:

Lee Johnson was a man with simple dreams. All he wanted was a steady job and a nice home for his wife and children, something better than the hard life he knew growing up. He never imagined that he would become the face of a David-and-Goliath showdown against one of the world’s most powerful corporate giants. But a workplace accident left Lee doused in a toxic chemical and facing a deadly cancer that turned his life upside down. In 2018, the world watched as Lee was thrust to the forefront of one the most dramatic legal battles in recent history.

The Monsanto Papers is the inside story of Lee Johnson’s landmark lawsuit against Monsanto. For Lee, the case was a race against the clock, with doctors predicting he wouldn’t survive long enough to take the witness stand. For the eclectic band of young, ambitious lawyers representing him, it was a matter of professional pride and personal risk, with millions of their own dollars and hard-earned reputations on the line.

With a gripping narrative force, The Monsanto Papers takes readers behind the scenes of a grueling legal battle, pulling back the curtain on the frailties of the American court system and the lengths to which lawyers will go to fight corporate wrongdoing and find justice for consumers.

Reviews

“A powerful story, well told, and a remarkable work of investigative journalism. Carey Gillam has written a compelling book from beginning to end, about one of the most important legal battles of our time.”  — Lukas Reiter, TV executive producer and writer for “The Blacklist,” “The Practice,” and “Boston Legal”

“The Monsanto Papers blends science and human tragedy with courtroom drama in the style of John Grisham. It is a story of corporate malfeasance on a grand scale – a chilling revelation of the chemical industry’s greed, arrogance, and reckless disregard for human life and the health of our planet. It is a must read.”  — Philip J. Landrigan, MD, Director, Program for Global Public Health and the Common Good, Boston College

“Veteran investigative journalist Carey Gillam tells Johnson’s story in her latest book, “The Monsanto Papers,” a fast-paced, engaging account of how Monsanto and Bayer’s fortunes changed dramatically in such a short span of time. Despite the subject matter — complicated science and legal proceedings — “The Monsanto Papers” is a gripping read that provides an easy-to-follow explanation of how this litigation unfolded, how the jurors reached their verdict and why Bayer appears to be, in effect, throwing up a white flag now.”  — St. Louis Post-Dispatch

“The author builds a convincing case that Monsanto was more interested in protecting the reputation of its cash cow than heeding scientific evidence of its dangerous properties. Gillam is especially good at rendering the complex dynamics of the legal personalities, which adds a further humanizing dimension to Johnson’s story…An authoritative takedown of a corporation that evidently cares little for public health.”  ― Kirkus

“Gillam narrates an of-the-moment reckoning with a major corporation whose products have been marketed as safe since the 1970s. As an examination of both corporate malfeasance and legal maneuvering in torts cases, Gillam’s book personifies the need for consumer protections and safety.”  ― Booklist

“A great read, a page turner. I was totally engrossed by the deception, distortions, and lack of decency of the company.”  — Linda S. Birnbaum, Former Director, National Institute of Environmental Health Sciences and National Toxicology Program, and Scholar in Residence, Duke University

“A powerful book that sheds light on Monsanto and others who have been untouchable for so long!”
— John Boyd Jr., Founder and President, National Black Farmers Association

Another Roundup study finds links to potential human health problems

Print Email Share Tweet

(Updated February 17, adding criticism of study)

A new scientific paper examining the potential health impacts of Roundup herbicides found links between exposure to the weed killing chemical glyphosate and an increase in a type of amino acid known to be a risk factor for cardiovascular disease.

The researchers made their determinations after exposing pregnant rats and their newborn pups to glyphosate and Roundup through drinking water. They said they looked specifically at the effects of glyphosate-based herbicides (GBH) on urinary metabolites and interactions with the gut microbiome in the animals.

The researchers said they found a significant increase of an amino acid called homocysteine in male rat pups exposed to glyphosate and Roundup.

“Our study provides initial evidence that exposures to commonly used GBH, at a currently acceptable human exposure dose, is capable of modifying urine metabolites in both rat adults and pups,” the researchers stated.

The paper, titled “Low-dose exposure of glyphosate-based herbicides disrupt the urine metabolome and its interaction with gut microbiota,” is authored by five researchers affiliated with the Icahn School of Medicine at Mount Sinai in New York and four from the Ramazzini Institute in Bologna, Italy. It was published in the journal Scientific Reports February 5.

The authors acknowledged many limitations with their study, including a small sample size, but said their work showed that “gestational and early-life low-dose exposure to glyphosate or Roundup significantly altered multiple urine metabolomic biomarkers, in both dams and offspring.”

The study is the first on urinary metabolomic changes induced by glyphosate-based herbicides at doses currently considered safe in humans, the researchers said.

The paper follows the publication last month of a study in the journal Environmental Health Perspectives that found glyphosate and a Roundup product can alter the composition of the gut microbiome in ways that may be linked to adverse health outcomes. Scientists from the Ramazzini Institute were also involved in that research.

Robin Mesnage, one of the authors of the paper published last month in Environmental Health Perspectives, took issue with the validity of the new paper. He said the data analysis showed the differences detected between the animals exposed to glyphosate and those not exposed – the control animals – could have been similarly detected with randomly generated data.

“Overall, the data analysis doesn’t support the conclusion that glyphosate disrupts the urine metabolome and the gut microbiota of the exposed animals,” said Mesnage. “This study will only further confuse a bit more the debate on the toxicity of glyphosate.”

Several recent studies on glyphosate and Roundup have found an array of concerns.

Bayer, which inherited Monsanto’s glyphosate-based herbicide brand and its glyphosate-tolerant genetically engineered seed portfolio when it bought the company in 2018, maintains that an abundance of scientific study over decades confirms that glyphosate does not cause cancer. The U.S. Environmental Protection Agency and many other international regulatory bodies also do not consider glyphosate products to be carcinogenic.

But the World Health Organization’s International Agency for Research on Cancer in 2015 said a review of scientific research found ample evidence that glyphosate is a probable human carcinogen.

Bayer has lost three out of three trials brought by people who blame their cancers on exposure to Monsanto’s herbicides, and Bayer last year said it would pay roughly  $11 billion to settle more than 100,000 similar claims.

 

 

New glyphosate papers point to “urgency” for more research on chemical impact to human health

Newly published scientific papers illustrate the ubiquitous nature of the weed killing chemical glyphosate and a need to better understand the impact exposure to the popular pesticide may be having on human health, including the health of the gut microbiome.

In one of the new papers, researchers from the University of Turku in Finland said that they were able to determine, in a “conservative estimate,” that approximately 54 percent of species in the core of the human gut microbiome are “potentially sensitive” to glyphosate. The researchers said they used a new bioinformatics method to make the finding.

With a “large proportion” of bacteria in the gut microbiome susceptible to glyphosate, the intake of glyphosate “may severely affect the composition of the human gut microbiome,” the authors said in their paper, which was published this month in the Journal of Hazardous Materials.

The microbes in the human gut include a variety of bacteria and fungi and are believed to impact immune functions and other important processes. Unhealthy gut microbiomes are believed by some scientists to contribute to a range of diseases.

“Although data on glyphosate residues in human gut systems are still lacking, our results suggest that glyphosate residues decrease bacterial diversity and modulate bacterial species composition in the gut,” the authors said. “We may assume that long-term exposure to glyphosate residues leads to the dominance of resistant strains in the bacterial community.”

The concerns about glyphosate’s impact on the human gut microbiome stem from the fact that glyphosate works by targeting an enzyme known as 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS.) This enzyme is critical to the synthesizing of essential amino acids.

“To determine the actual impact of glyphosate on the human gut microbiota and other organisms, further empirical studies are needed to reveal glyphosate residues in food, to determine the effects of pure glyphosate and commercial formulations on microbiomes and to assess the extent to which our EPSPS amino acid markers predict bacterial susceptibility to glyphosate in in vitro and real-world scenarios,” the authors of the new paper concluded.

In addition to the six researchers from Finland, one of the authors of the paper is affiliated with the department of biochemistry and biotechnology at Rovira i Virgili University, Tarragona, Catalonia, in Spain.

“The consequences for human health are not determined in our study. However, based on previous studies… we know that alterations in the human gut microbiome may be connected to several diseases,” University of Turku researcher Pere Puigbo said in an interview.

“I hope that our research study opens the door to further experiments, in-vitro and in the field, as well as population-based studies to quantify the effect the use of glyphosate has on human populations and other organisms,” Puigbo said.

Introduced in 1974

Glyphosate is the active ingredient in Roundup herbicides and hundreds of other weed killing products sold around the world. It was introduced as a weed killer by Monsanto in 1974 and grew to become the most widely used herbicide after Monsanto’s introduction in the 1990s of crops genetically engineered to tolerate the chemical. Residues of glyphosate are commonly found on food and in water. Consequently, residues are also often detected in the urine of people exposed to glyphosate through either diet and/or application.

U.S. regulators and Monsanto owner Bayer AG maintain there are no human health concerns with glyphosate exposure when the products are used as intended, including from residues in the diet.

The body of research contradicting those claims is growing, however. The research on the potential impacts of glyphosate on the gut microbiome is not nearly as robust as the literature associating glyphosate to cancer, but is an area many scientists are probing.

In a somewhat related paper published this month, a team of researchers from Washington State University and Duke University said that they had found a correlation between the levels of bacteria and fungi in the gastrointestinal tracts of children and the chemicals found in their homes. The researchers did not look at glyphosate specifically, but were alarmed to find that children with higher levels of common household chemicals in their bloodstream showed a reduction in the amount and diversity of important bacteria in their gut.

Glyphosate in urine

An additional scientific paper published this month underscored a need for better and more data when it comes to glyphosate exposure and children.

The paper, published in the journal Environmental Health by researchers from the Institute for Translational Epidemiology at the Icahn School of Medicine at Mount Sinai in New York, is the outcome of a literature review of multiple studies reporting actual values of glyphosate in people.

The authors said they analyzed five studies published in the last two years reporting glyphosate levels measured in people, including one study in which urinary glyphosate levels were measured in children living in rural Mexico. Of 192 children living in the Agua Caliente area, 72.91 percent had detectable levels of glyphosate in their urine, and all of the 89 children living in Ahuacapán, Mexico, had detectable levels of the pesticide in their urine.

Even when including additional studies, overall, there is sparse data regarding glyphosate levels in people. Studies globally total only 4,299 people, including 520 children, the researchers said.

The authors concluded that it is not currently possible to understand the “potential relationship” between glyphosate exposure and disease, especially in children, because data collection on exposure levels in people is limited and not standardized.

They noted that despite the lack of solid data about the impacts of glyphosate on children, the amount of glyphosate residues legally allowed by U.S. regulators on food has increased dramatically over the years.

“There are gaps in the literature on glyphosate, and these gaps should be filled with some urgency, given the large use of this product and its ubiquitous presence,” said author Emanuela Taioli.

Children are especially vulnerable to environmental carcinogens and tracking exposure to products such as glyphosate in children is “a pressing public health priority,” according to the authors of the paper.

“As with any chemical, there are multiple steps involved in evaluating risk, which include gathering information about human exposures, so that the levels that produce harm in one population or animal species can be compared to typical exposure levels,” the authors wrote.

“However, we have previously shown that data on human exposure in workers and the general population are very limited. Several other gaps in knowledge exist around this product, for example results on its genotoxicity in humans are limited. The continued debate regarding the effects of glyphosate exposure makes establishing exposure levels in the general public a pressing public health issue, especially for the most vulnerable.”

The authors said monitoring of urinary glyphosate levels should be conducted in the general population.

“We continue to suggest that inclusion of glyphosate as a measured exposure in nationally representative studies like the National Health and Nutrition Examination Survey will allow for a better understanding of the risks that glyphosate may pose and allow for better monitoring of those who are most likely to be exposed and those who are more susceptible to the exposure,” they wrote.

California Supreme Court denies review of Monsanto Roundup trial loss

The California Supreme Court will not review a California man’s trial win over Monsanto, dealing another blow to Monsanto’s German owner, Bayer AG.

The decision to deny a review in the case of Dewayne “Lee” Johnson marks the latest in a string of court losses for Bayer as it tries to complete settlements with close to 100,000 plaintiffs who each claim they or their loved ones developed non-Hodgkin lymphoma from exposure to Roundup and other Monsanto weed killers. Juries in each of three trials held to date have found not only that the company’s glyphosate-based herbicides cause cancer but also that Monsanto spent decades hiding the risks.

“We are disappointed with the Court’s decision not to review the intermediate appeals court’s decision in Johnson and will consider our legal options for further review of this case,” Bayer said in a statement.  

The Miller Firm, Johnson’s Virginia-based law firm, said the California Supreme Court’s decision denied “Monsanto’s latest attempt to skirt responsibility” for causing Johnson’s cancer.

“Multiple judges have now affirmed the jury’s unanimous finding that Monsanto maliciously  concealed Roundup’s cancer risk and caused Mr. Johnson to develop a deadly form of cancer. The time has come for Monsanto to end its baseless appeals and pay Mr. Johnson the money it owes him,” the firm said.

A unanimous jury found in August 2018 that exposure to Monsanto’s herbicides  caused Johnson to develop a deadly form of non-Hodgkin lymphoma. The jury further found that Monsanto acted to hide the risks of its products in conduct so egregious that the company should pay Johnson $250 million in punitive damages on top of $39 million in past and future compensatory damages.

Upon appeal from Monsanto, the trial judge reduced the $289 million to $78 million. An appeals court then cut the award to $20.5 million, citing the fact that Johnson was expected to live only a short time.

The appeals court said it reduced the damages award despite finding there was “abundant” evidence that glyphosate, together with the other ingredients in Roundup products, caused Johnson’s cancer and that “there was overwhelming evidence that Johnson has suffered, and will continue to suffer for the rest of his life, significant pain and suffering.”

Both Monsanto and Johnson sought review by the California Supreme Court, with Johnson asking for restoration of a higher damage award and Monsanto seeking to reverse the trial judgment.

Bayer has reached settlements with several of the leading law firms who collectively represent a significant share of the claims brought against Monsanto. In June, Bayer said it would provide $8.8 billion to $9.6 billion to resolve the litigation.
