California Supreme Court denies review of Monsanto Roundup trial loss

Print Email Share Tweet

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.

Bayer’s Monsanto headache persists

The migraine that is Monsanto doesn’t appear to be going away anytime soon for Bayer AG.

Efforts at settling the mass of lawsuits brought in the United States by tens of thousands of people who claim Monsanto’s Roundup herbicides gave them cancer continue to inch forward, but are not addressing all outstanding cases, nor are all plaintiffs offered settlements agreeing to them.

In a letter to U.S. District Judge Vince Chhabria, Texas attorney David Diamond said that representations made by the lawyers leading settlement talks with Bayer on behalf of plaintiffs did not accurately reflect the situation for his own clients. He cited a “lack” of “settlement-related experiences” with Bayer and he requested that Judge Chhabria advance several of Diamond’s cases forward for trials.

“Leadership’s representations regarding settlement do not represent my clients’ settlement
related experiences, interests or position,” Diamond told the judge.

Diamond wrote in the letter that he has 423 Roundup clients, including 345 who have cases pending before Chhabria in the multidistrict litigation (MDL) in the U.S. District Court for the Northern District of California. Alongside the MDL are thousands of plaintiffs whose cases are pending in state courts.

Diamond’s outreach to the judge followed a hearing late last month in which several of the leading firms in the litigation and lawyers for Bayer told Chhabria they were close to resolving most, if not all, of the cases before the judge.

Bayer has reached important 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.

But controversy and conflict have dogged the overall settlement offers.

Several plaintiffs represented by the large firms and who spoke on condition that their names not be used, said they are not agreeing to the terms of the settlements, meaning their cases will be directed into mediation and, if that fails, to trials.

After buying Monsanto in 2018, Bayer has been struggling to figure out how to put an end to the litigation that includes more than 100,000 plaintiffs. The company lost all three of the three trials held to date and has lost the early rounds of appeals seeking to overturn the trial losses. Juries in each of the trials found that Monsanto’s glyphosate-based herbicides, such as Roundup, do cause cancer and that Monsanto spent decades hiding the risks.

The company’s efforts to resolve the litigation have been stymied in part by the challenge of how to head off claims that could be brought in the future by people who develop cancer after using the company’s herbicides.

Problems Just Keep Mounting  

Bayer has threatened to file for bankruptcy if it cannot quell the Roundup litigation and on Wednesday the company issued a profit warning and announced billions in cost cuts, citing a “lower than expected outlook in the agricultural market” amid other factors. The news sent shares in the company tumbling.

In reporting Bayer’s troubles Barron’s noted: “The problems just keep mounting for Bayer and its investors, who by now must be used to regular bouts of disappointing news. The stock has now fallen more than 50% since the Monsanto deal was closed in June 2018. “This latest update only adds to the case for the Monsanto deal being one of the worst in corporate history.”

Roundup cancer trials still a threat to Bayer, but settlement talks progressing

Print Email Share Tweet

Lawyers for Monsanto owner Bayer AG and for plaintiffs suing Monsanto told a federal judge on Thursday that they were continuing to make progress in settling sweeping nationwide litigation brought by people who claim Monsanto’s Roundup caused them to develop cancer.

In a video hearing, Bayer lawyer William Hoffman told U.S. District Judge Vince Chhabria the company had reached deals – or was close to reaching deals – to resolve more than 3,000 lawsuits that are grouped together in multidistrict litigation (MDL) filed in U.S. District Court for the Northern District of California.

The company separately has already settled thousands of cases outside the MDL, cases that have been proceeding through state courts. But controversy and conflict have dogged the overall settlement offers, with allegations from some plaintiffs’ firms that Bayer reneged on agreements reached months ago, and some plaintiffs’ firms unwilling to agree to what they consider inadequate offers from Bayer.

There was no discussion of those complaints, however,  in Thursday’s hearing, with both sides expressing optimistic views.

“The company has moved forward and finalized several agreements with firms…. we’re also hopefully going to finalize additional agreements in the next several days,” Hoffman told the judge.

“Where we are right now… these figures are somewhat estimates but I think they are reasonably close: There are approximately 1,750 cases that are subject to agreements between the company and law firms and another approximately 1,850 to 1,900 cases that are in various stages of discussion right now,” Hoffman said. “We are working to put in place a program to accelerate discussions and hopefully bring agreements to fruition with those firms.”

Plaintiffs’ lawyer Brent Wisner told the judge it was important to note that there remain a “handful of cases” within the MDL that are not settled yet. But, he said – “We anticipate they will be shortly.”

Judge Chhabria said that given the progress he will continue a stay of the Roundup litigation until November 2 but that he will start moving cases to trial if they are not resolved by that point.

Bayer Bad Dealing Alleged

The cooperative tone expressed in Thursday’s hearing was a far cry from a hearing held last month when plaintiffs’ attorney Aimee Wagstaff  told Judge Chhabria that Bayer was not honoring tentative settlement agreements made in March and intended for finalization in July.

Bayer announced in June that it had reached a $10 billion settlement with U.S. law firms to resolve most of more than 100,000 Roundup cancer claims. But at that time the only major law firms leading the litigation that had final signed agreements with Bayer were The Miller Firm and Weitz & Luxenburg.

The Miller Firm’s deal alone totaled $849 million to cover the claims of more than 5,000 Roundup clients, according to settlement documents.

The  California-based Baum Hedlund Aristei &  Goldman law firm; the Andrus Wagstaff firm from Colorado; and the Moore Law Group of Kentucky had tentative deals but not final agreements.

According to a letter written by Wagstaff filed with the court, Bayer requested repeated extensions until the deal with her firm fell apart in mid-August. After reporting the issues to Judge Chhabria, the settlement talks resumed and were ultimately resolved with the three firms this month.

Some details of how the settlements will be administered were filed earlier this week in a court in Missouri. The Garretson Resolution Group, Inc., doing business as Epiq Mass Tort, will act as the
Lien Resolution Administrator,” for instance, for clients of Andrus Wagstaff whose settlement dollars will need to be used in part or in whole to repay cancer treatment expenses paid by Medicare.

Bayer bought Monsanto in 2018 just as the first Roundup cancer trial was getting underway. It has since lost all three of the three trials held to date and has lost the early rounds of appeals seeking to overturn the trial losses. Juries in each of the trials found that Monsanto’s herbicides do cause cancer and that Monsanto spent decades hiding the risks.

The jury awards totaled well over $2 billion, though the judgments have been ordered reduced by trial and appellate court judges.

Bayer had threatened to file for bankruptcy if no nationwide settlement was reached, according to communications from the plaintiffs’ firms to their clients.

Bayer inks deals with three Roundup cancer law firms as settlement progresses

Bayer AG has reached final settlement terms with three major law firms representing thousands of plaintiffs who claim exposure to Monsanto’s glyphosate-based herbicides caused them to develop non-Hodgkin lymphoma.

The new deals have been  made with California-based Baum Hedlund Aristei &  Goldman law firm; the Andrus Wagstaff firm from Colorado; and the Moore Law Group of Kentucky. The firms each filed notification of the deals with the U.S. District Court for the Northern District of California on Monday.

The deals come after allegations by the three law firms that Bayer was reneging on terms of agreements already made months earlier. The firms told the court Monday that they each now have a “fully-executed and binding Master Settlement Agreement with Monsanto.”

Notably, the deals mark a critical step toward bringing closure to the five-year-old mass tort litigation that now tallies more than 100,000 claims brought by people from around the United States who used Roundup and other glyphosate-based herbicides made by Monsanto before they developed cancer.

Bayer bought Monsanto in 2018 just as the first Roundup cancer trial was getting underway. It has since lost all three of the three trials held to date and has lost the early rounds of appeals seeking to overturn the trial losses. Juries in each of the trials found that Monsanto’s herbicides do cause cancer and that Monsanto spent decades hiding the risks.

The jury awards totaled well over $2 billion, though the judgments have been ordered reduced by trial and appellate court judges.

Bayer had threatened to file for bankruptcy if no nationwide settlement was reached, according to communications from the plaintiffs’ firms to their clients.

Bayer announced in June that it had reached a $10 billion settlement with U.S. law firms to resolve most of more than 100,000 Roundup cancer claims. But at that time only two of the major law firms in the sweeping litigation had final signed agreements with Bayer – The Miller Firm and Weitz & Luxenburg, according to sources close to the negotiations. The Baum firm, the Andrus Wagstaff firm and the Moore firm had memorandums of understanding but not final agreements, sources said.

The company’s efforts to resolve the litigation have been stymied in part by the challenge of how to head off claims that could be brought in the future by people who develop cancer after using the company’s herbicides. Bayer tried to get court approval for a plan that would have delayed the filing of new Roundup cancer cases for four years, and would have established a five-member “science panel” to determine whether Roundup can cause non-Hodgkin lymphoma, and if so, at what minimum exposure levels.  If the panel determined there was no causal connection between Roundup and non-Hodgkin lymphoma then the class members would be barred from future such claims.

U.S. District Judge Vince Chhabria rejected the plan,  sending Bayer back to the drawing board.

Bayer had said Thursday that it was making progress in the development of a “revised” plan to resolve potential future Roundup litigation. The details of the revised class plan will be finalized over the coming weeks, according to Bayer.

Several plaintiffs have been unhappy with the settlement, saying they will not receive very much money despite years of expensive cancer treatments and ongoing pain and suffering. Indeed, many plaintiffs have died while waiting for a resolution.

On September 9, lawyers for Marie Bernice Dinner and her husband Bruce Dinner filed notice with the court that 73-year-old Marie died on June 2 from the non-Hodgkin lymphoma she and her husband alleged was caused by her exposure to Monsanto’s weed killers.

Lawyers for Bruce Dinner asked the court to allow them to amend the complaint against Monsanto to add a claim for wrongful death. The couple was married 53 years and have two children and four grandchildren.

“Marie Bernice was an extraordinary person.  Her death should have been prevented,” said lawyer Beth Klein, who is representing the family.

Glyphosate in chicken poop used as fertilizer is hurting food production, researchers say

Print Email Share Tweet

Scientists brought more bad news to light regarding the widely used herbicide glyphosate, better known as Roundup, in a new research paper published this month.

Researchers from the University of Turku in Finland revealed in a paper published in the journal  Science of The Total Environment that manure from poultry used as fertilizer can decrease crop yields when the manure contains residues of glyphosate-based herbicides, such as Roundup. Fertilizers are meant to increase crop production, so the evidence that glyphosate residues can have the opposite effect is significant.

Poultry litter, as the manure is called, is often used as a fertilizer, including in organic agriculture, because it is considered rich in essential nutrients. Use of the poultry litter as fertilizer has been growing both in farming and in horticulture and home gardens.

While use is growing, the “possible risks associated with the accumulation of agrochemicals in poultry manure are still largely ignored,” the Finland researchers warned.

Organic farmers have been growing increasingly worried about traces of glyphosate in manure fertilizer that is allowed in organic production, but many in the industry are reluctant to publicize the issue.

Farmers spray glyphosate directly onto a number of crops grown around the world, including soybeans, corn, cotton, canola and other crops genetically engineered to withstand glyphosate treatments. They also often directly spray such crops as wheat and oats, which are not genetically engineered – shortly before harvest to dry the crops out.

Given the amount of glyphosate-based herbicides used to treat crops that are used in animal feed, as well as the amount of manure used as fertilizer, “we should definitely be aware that this kind of a risk exists,” said one of the authors of study, Anne Muola.

“Nobody seems very eager to talk too loudly about it.” Muola noted.

The heavy use of glyphosate herbicides directly onto food crops has been promoted by Monsanto – now a unit of Bayer AG – since the 1990s, and glyphosate use is so ubiquitous that residues are commonly found in food, water and even air samples.

Because there are glyphosate residues in human and animal food, detectable glyphosate levels are commonly found in human urine and animal manure.

These glyphosate residues in fertilizer are a problem for growers for many reasons, according to the Finland researchers.

“We found that poultry manure can accumulate high residues of (glyphosate-based herbicides), decrease plant growth and reproduction, and thus inhibit the growth-promoting effects of manure when applied as fertilizer,” the paper states. “These results demonstrate that the residues pass through the digestive process of birds, and more importantly, they persist in the manure fertilizer over long periods.”

The researchers said the glyphosate residues can persist in ecological systems, affecting several non-target organisms over many years.

The consequences, they said, include decreased efficiency of manure as fertilizer; long-lasting glyphosate-based herbicide contamination of agricultural cycles; “uncontrolled” glyphosate contamination of non-target areas; increased threat to “vulnerable non-target organisms,” and an increased risk of emerging resistances to glyphosate.

The researchers said more studies should be done to reveal the extent of glyphosate contamination in organic fertilizers and how that impacts sustainability.

The Finland research adds to evidence of the dangers of glyphosate residues in fertilizer, according to agricultural experts.

“The impacts of glyphosate residue that have accumulated in poultry excrements is a largely overlooked area of research,”  said Rodale Institute soil scientist, Dr. Yichao Rui. “But what research does exist has shown that those residues can have a negative effect on crops, if poultry manure was used as a fertilizer. Glyphosate residues in fertilizers have been shown to have negative effects on plants, soil microbiomes, and microbes associated with plants and animals including humans through the food chain. When this contamination is unintentionally spread through fertilizer, it places a severe strain on biodiversity and ecosystem functions and services.”

Worldwide 9.4 million tons of glyphosate have been sprayed on fields – enough to spray nearly half a pound of Roundup on every cultivated acre of land in the world.

In 2015, the World Health Organization’s International Agency for Research on Cancer (IARC) classified glyphosate as “probably carcinogenic to humans” after reviewing years of published and peer-reviewed scientific studies. The team of international scientists found there was a particular association between glyphosate and non-Hodgkin lymphoma.

Tens of thousands of people in the United States suffering from non-Hodgkin lymphoma have sued Monsanto, and in three trials held to date, juries have found that the company’s glyphosate herbicides were to blame for causing the cancers.

Additionally, an assortment of animal studies released this summer indicate that glyphosate exposures impact reproductive organs and could threaten fertility, adding fresh evidence that the weed killing agent might be an endocrine disruptor. Endocrine disrupting chemicals may mimic or interfere with the body’s hormones and are linked with developmental and reproductive problems as well as brain and immune system dysfunction.

Dying man asks California Supreme Court to restore jury award in Monsanto Roundup case

The school groundskeeper who won the first-ever trial over allegations that Monsanto’s Roundup causes cancer is asking the California Supreme Court to restore $250 million in punitive damages awarded by the jury who heard his case but then slashed by an appeals court to $20.5 million.

Notably, the appeal by plaintiff Dewayne “Lee” Johnson has larger implications than his own individual case. Johnson’s lawyer are urging the court to address a legal twist that can leave people such as Johnson who are facing death in the near term with lower damage awards than others expected to live many years in suffering and pain.

“It is long past time for California courts to recognize, as other courts do, that life itself has value and that those who maliciously deprive a plaintiff of years of life should be made to fully compensate that plaintiff and be punished accordingly,” Johnson’s attorneys wrote in their request for the state supreme court review. “The jury ascribed meaningful value to Mr. Johnson’s life, and for that he is grateful. He asks this Court to respect the jury’s decision and restore that value. ”

A unanimous jury found in August 2018 that exposure to Monsanto’s glyphosate-based herbicides, known best by the brand name Roundup, caused Johnson to develop 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, which was purchased by the German company Bayer AG in 2018, the trial judge reduced the $289 million to $78 million. Monsanto appealed seeking either a new trial or a reduced award. Johnson cross-appealed seeking reinstatement of his full damage award.

The appeals court in the case then cut the award to $20.5 million, citing the fact that Johnson was expected to live only a short time.

The appeals court 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.”

The Johnson trial was covered by media outlets around the world and put a spotlight on Monsanto’s efforts to manipulate the scientific record on glyphosate and Roundup and its efforts to quiet critics and influence regulators.  Lawyers for Johnson presented jurors with internal company emails and other records showing Monsanto scientists discussing ghostwriting scientific papers to try to shore up support for the safety of the company’s products, along with communications detailing plans to discredit critics, and to quash a government evaluation of the toxicity of glyphosate, the key chemical in Monsanto’s products.

Johnson’s trial victory spurred a frenzied filing of tens of thousands of additional lawsuits. Monsanto lost three out of three trials before agreeing this June to pay more than $10 billion to settle close to 100,000 such claims.

The settlement is still in flux, however, as Bayer wrestles with how to forestall future litigation.

In an interview, Johnson said he knew the legal battle with Monsanto could continue for many more years but he was committed to trying to hold the company accountable. He has managed to keep his illness in check so far with regular chemotherapy and radiation treatments, but is not certain how long that will continue.

“I don’t think any amount would be enough to punish that company,” Johnson said.

Appeals court denies Monsanto bid for Roundup case rehearing

Print Email Share Tweet

A California appeals court on Tuesday rejected Monsanto’s effort to trim $4 million from the amount of money it owes a California groundskeeper who is struggling to survive cancer that a jury found was caused by the man’s exposure to Monsanto’s Roundup herbicides.

The Court of Appeal for the First Appellate District of California also rejected the company’s request for a rehearing of the matter.  The court’s decision followed its ruling last month slamming Monsanto  for its denial of the strength of the evidence that its glyphosate-based weed killers cause cancer. In that July ruling, the court said that plaintiff Dewayne “Lee” Johnson had presented “abundant” evidence that Monsanto’s weed killer caused his cancer.  “Expert after expert provided evidence both that Roundup products are capable of causing non-Hodgkin’s lymphoma…  and caused Johnson’s cancer in particular,” the appeals court stated in its July decision.

In that decision from last month, the appeals court did, however, cut the damage award owed to Johnson, ordering Monsanto to pay $20.5 million, down from $78 million ordered by the trial judge and down from $289 million ordered by the jury who decided Johnson’s case in August 2018.

In addition to the $20.5 million Monsanto owes Johnson, the company is ordered to pay $519,000 in costs.

Monsanto, which was bought by Bayer AG in 2018, had urged the court to cut the award to Johnson to $16.5 million.

Dicamba decision also stands

Tuesday’s court decision followed a decision issued Monday by the U.S. Court of Appeals for the Ninth Circuit denying a rehearing of the court’s June decision to vacate the approval of the dicamba-based weed killing product Bayer inherited from Monsanto. That June ruling also effectively banned dicamba-based herbicides made by BASF and Corteva Agriscience.

The companies had petitioned for a broader group of judges from the Ninth Circuit judges to rehear the case, arguing that the decision to revoke regulatory approvals for the products was unfair. But the court flatly rejected that rehearing request.

In its June decision, the Ninth Circuit said the Environmental Protection Agency (EPA) had violated the law when it approved the dicamba products developed by Monsanto/Bayer, BASF and Corteva.

The court ordered an immediate ban on use of each of the company’s dicamba products, finding that the EPA “substantially understated the risks” of the dicamba herbicides and “failed entirely to acknowledge other risks.”

The court decision banning the company’s dicamba products triggered an uproar in farm country because many soybean and cotton farmers planted millions of acres of genetically altered dicamba-tolerant crops developed by Monsanto with the intent of treating weeds in those fields with the dicamba herbicides made by the three companies. Similar to “Roundup Ready” glyphosate-tolerant crops, the dicamba-tolerant crops allow farmers to spray dicamba over their fields tyo kill weeds without harming their crops.

When Monsanto, BASF and DuPont/Corteva rolled out their dicamba herbicides a few years ago they  claimed the products would not volatize and drift into neighboring fields as older versions of dicamba weed killing products were known to do. But those assurances proved false amid widespread complaints of dicamba drift damage.

More than one million acres of crops not genetically engineered to tolerate dicamba were reported damaged last year in 18 states, the federal court noted in its June ruling.

New weed killer studies raise concern for reproductive health

Print Email Share Tweet

As Bayer AG seeks to discount concerns that Monsanto’s glyphosate-based herbicides cause cancer, several new studies are raising questions about the chemical’s potential impact on reproductive health.

An assortment of animal studies released this summer indicate that glyphosate exposures impact reproductive organs and could threaten fertility, adding fresh evidence that the weed killing agent might be an endocrine disruptor. Endocrine disrupting chemicals may mimic or interfere with the body’s hormones and are linked with developmental and reproductive problems as well as brain and immune system dysfunction.

In a paper published last month in Molecular and Cellular Endocrinology, four researchers from Argentina said that studies contradict assurances by the U.S. Environmental Protection Agency (EPA) that glyphosate is safe.

The new research comes as Bayer is attempting to settle more than 100,000 claims brought in the United States by people who allege exposure to Monsanto’s Roundup and other glyphosate-based herbicide products caused them to develop non-Hodgkin lymphoma. The plaintiffs in the nationwide litigation also claim Monsanto has long sought to hide the risks of its herbicides.

Bayer inherited the Roundup litigation when it bought Monsanto in 2018, shortly before the first of three trial victories for plaintiffs.

The studies also come as consumer groups work to better understand how to reduce their exposure to glyphosate through diet. A study published Aug. 11 found that after switching to an organic diet for just a few days, people could cut the levels of glyphosate found in their urine by more than 70 percent. Notably, the researchers found that the children in the study had much higher levels of glyphosate in their urine than did the adults. Both adults and children saw large drops in the presence of the pesticide following the diet change.

Glyphosate, the active ingredient in Roundup, is the most widely used weed killer in the world. Monsanto introduced glyphosate-tolerant crops in the 1990s to encourage farmers to spray glyphosate directly over whole fields of crops, killing weeds but not the genetically altered crops. The widespread use of glyphosate, by farmers as well as homeowners, utilities and public entities, has drawn growing concern over the years because of its pervasiveness and fears about what it could be doing to human and environmental health. The chemical is now found commonly in food and water and in human urine.

According to the Argentinian scientists, some of the reported effects of glyphosate seen in the new animal studies are due to exposure to high doses; but there is new evidence showing that even low dose exposure could also alter the development of the female reproductive tract, with consequences on fertility. When animals are exposed to glyphosate before puberty, alterations are seen in the development and differentiation of ovarian follicles and the uterus, the scientists said. Additionally, exposure to herbicides made with glyphosate during gestation could alter the development of the offspring. It all adds up to show that glyphosate and glyphosate-based herbicides are endocrine disruptors, the researchers concluded.

Agricultural scientist Don Huber, professor emeritus from Purdue University, said the new research expands on knowledge about the potential scope of damage associated with glyphosate and glyphosate-based herbicides and provides a “better grasp of understanding the seriousness of the exposure that is ubiquitous in our culture now.”

Huber has warned for years that Monsanto’s Roundup might be contributing to fertility problems in livestock.

One noteworthy study published online in July in the journal Food and Chemical Toxicology,  determined that glyphosate or glyphosate-based herbicides disrupted “critical hormonal and uterine molecular targets” in exposed pregnant rats.

A different study recently published in the journal Toxicology and Applied Pharmacology by researchers from Iowa State University looked at glyphosate exposure in mice. The researchers concluded that chronic low-level exposure to glyphosate “alters the ovarian proteome” (a set of expressed proteins in a given type of cell or organism) and “may ultimately impact ovarian function. In a related paper from the same two Iowa State researchers and one additional author, published in Reproductive Toxicology, the researchers said they did not find endocrine disrupting effects in the mice exposed to glyphosate, however.  

Researchers from the University of Georgia reported in the journal Veterinary and Animal Science that consumption by livestock of grain laced with glyphosate residues appeared to carry potential harm for the animals, according to a review of studies on the topic. Based on the literature review, glyphosate-based herbicides appear to act as “reproductive toxicants, having a wide range of effects on both the male and female reproductive systems,” the researchers said.

Alarming results were also seen in sheep. A study published in the journal Environmental Pollution looked at the impacts of glyphosate exposure on the development of the uterus in female lambs. They found changes that they said might affect the female reproductive health of sheep and show glyphosate-based herbicides acting as an endocrine disruptor.

Also published in Environmental Pollution, scientists from Finland and Spain said in a new paper that they had performed the first long-term experiment of the effects of “sub-toxic” glyphosate exposure on poultry. They experimentally exposed female and male quails to glyphosate-based herbicides from the ages of 10 days to 52 weeks.

The researchers concluded that the glyphosate herbicides could “modulate key physiological pathways, antioxidant status, testosterone, and the microbiome” but they did not detect effects on reproduction. They said the effects of glyphosate may not always be visible with “traditional, especially short-term, toxicology testing, and such testing may not fully capture the risks…”

Glyphosate and Neonicotinoids

One of the newest studies looking at glyphosate impacts on health was published this month in the International Journal of Environmental Research and Public Health.  Researchers concluded that glyphosate as well as the insecticides thiacloprid and imidacloprid, were potential endocrine disruptors.

The insecticides are part of the neonicotinoid class of chemicals and are among the most heavily used insecticides in the world.

The researchers said that they monitored the effect of glyphosate and the two neonicotinoids on two critical targets of the endocrine system: Aromatase, the enzyme responsible for estrogen biosynthesis, and estrogen receptor alpha, the main protein promoting estrogen signaling.

Their results were mixed. The researchers said with respect to glyphosate, the weed killer inhibited aromatase activity but the inhibition was “partial and weak.” Importantly the researchers said glyphosate did not induce estrogenic activity. The results were “consistent” with the screening program conducted by U.S. Environmental Protection Agency, which concluded that “there is no convincing evidence of a potential interaction with the estrogen pathway for glyphosate,” they said.

The researchers did see estrogenic activity with imidacloprid and thiacloprid, but at concentrations higher than the pesticide levels measured in human biological samples. The researchers concluded that “low doses of these pesticides should not be considered harmless,” however, because these pesticides, together with other endocrine disrupting chemicals, “might cause an overall estrogenic effect.”

The varying findings come as many countries and localities around the world evaluate whether or not to limit or ban continued use of glyphosate herbicides.

A California appeals court ruled last month that there was “abundant” evidence that glyphosate, together with the other ingredients in Roundup products, caused cancer.

U.S. study shows switch to organic diet can quickly clear pesticide from our bodies

Print Email Share Tweet

A new study published Tuesday found that after switching to an organic diet for just a few days, people could cut the levels of a pesticide linked to cancer found in their urine by more than 70 percent.

The researchers collected a total of 158 urine samples from four families –seven adults and nine children – and examined the samples for the presence of the weed killer glyphosate, which is the active ingredient in Roundup and other popular herbicides. The participants spent five days on a completely non-organic diet and five days on a completely organic diet.

“This study demonstrates that shifting to an organic diet is an effective way to reduce body burden of glyphosate… This research adds to a growing body of literature indicating that an organic diet may reduce exposure to a range of pesticides in children and adults,” states the study, which was published in the journal Environmental Research.

Notably, the researchers found that the children in the study had much higher levels of glyphosate in their urine than did the adults. Both adults and children saw large drops in the presence of the pesticide following the diet change. The mean urinary glyphosate levels for all subjects dropped 70.93 percent.

Despite its small size, the study is an important one because it shows people can markedly reduce their exposures to pesticides in food even without regulatory action, said Bruce Lanphear, Professor of Health Sciences at Simon Fraser University.

Lanphear noted that the study showed children appear to be more heavily exposed than adults, though the reason is unclear.  “If the food is contaminated with pesticides, they will have a higher body burden,” Lanphear said.

Roundup and other glyphosate herbicides are commonly sprayed directly over the top of growing fields of corn, soybeans, sugar beets, canola, wheat, oats and many other crops used to make food, leaving traces in finished food products consumed by people and animals.

The Food and Drug Administration has found glyphosate even in oatmeal  and honey, among other products. And consumer groups have documents glyphosate residues in an array of snacks and cereals.

But glyphosate and glyphosate-based herbicides such as Roundup have been linked to cancer and other illness and disease in several studies over the years and growing awareness of the research has led to growing fears about exposure to the pesticide through the diet.

Many groups have documented the presence of glyphosate in human urine in recent years. But there have been few studies comparing glyphosate levels in people eating a conventional diet versus a diet made up only of foods grown organically, without the use of pesticides such as glyphosate.

“The outcomes of this research validate the previous research in which organic diets could minimize the intakes of agrochemicals, such as glyphosate,” said Chensheng Lu, adjunct professor of the University of Washington School of Public Health and honorary professor, Southwest University, Chongqing China.

“In my opinion, the underlying message of this paper is to encourage producing more organic foods for people who want to protect themselves from the exposure of agrochemicals. This paper has proven again this absolute right pathway for prevention and protection,” Lu said.

The study was authored by John Fagan and Larry Bohlen, both of the Health Research Institute in Iowa, along with Sharyle Patton, director of the Commonweal Biomonitoring Resource Center in California and Kendra Klein, a staff scientist at Friends of the Earth, a consumer advocacy group.

The families participating in the study live in Oakland, California, Minneapolis, Minnesota, Baltimore, Maryland and Atlanta, Georgia.

The study is the second of a two-part research project. In the first, levels of 14 different pesticides were measured in the urine of participants.

Glyphosate is of particular concern because it is the most widely used herbicide in the world and is sprayed on so many food crops. The International Agency for Research on Cancer, part of the World Health Organization, said in 2015 that researched showed glyphosate to be a probable human carcinogen.

Tens of thousands of people have sued Monsanto claiming exposure to Roundup caused them to develop non-Hodgkin lymphoma, and many countries and localities around the world have recently limited or banned glyphosate herbicides or are considering doing so.

Bayer, which bought Monsanto in 2018, is attempting to settle more than 100,000 such claims brought in the United States. The plaintiffs in the nationwide litigation also claim Monsanto has long sought to hide the risks of its herbicides.

A California appeals court ruled last month that there was “abundant” evidence that glyphosate, together with the other ingredients in Roundup products, caused cancer.
