Dicamba Fact Sheet

Posted on by Carey Gillam

Dicamba (3,6-dichloro-2-methoxybenzoic acid) is a broad-spectrum herbicide first registered in 1967. The herbicide is used on agricultural crops, fallow land, pastures, turfgrass and rangeland. Dicamba is also registered for non-agricultural uses in residential areas and other sites, such as golf courses. At these types of sites, it is primarily used to control broadleaf weeds such as dandelions, chickweed, clover and ground ivy.

Dicamba can be found in liquids, dusts and granule products. There are more than 1,000 products sold in the United States that include dicamba, according to the National Pesticide Information Center.

Dicamba’s mode of action is as an auxin agonist: it produces uncontrollable growth that leads to plant death.

Environmental Concerns 

Older versions of dicamba were known to drift far from where they were applied, and typically were not used widely during warm growing months when they could kill off-target crops or trees.

The Environmental Protection Agency approved the registration of new dicamba formulations in 2016, however, allowing for a new use of – “over-the-top” applications on growing dicamba-tolerant cotton and soybean plants. Scientists warned the new uses would result in dicamba drift damage.

The new uses for dicamba came about because of the development of widespread weed resistance to glyphosate-based herbicides, including the popular Roundup brand, introduced by Monsanto in the 1970s. In the 1990s, Monsanto introduced glyphosate-tolerant crops, and encouraged famers to use its “Roundup Ready” cropping systems. Farmers could plant Monsanto’s genetically engineered glyphosate-tolerant soybeans, corn, cotton and other crops, and then spray glyphosate herbicides such as Roundup directly over the top of the growing crops without killing them. The system made weed management easier for farmers as they could spray the chemicals directly over their entire fields during the growing season, wiping out weeds that competed with the crops for moisture and soil nutrients.

The popularity of the Roundup Ready system led to a surge in weed resistance, however, leaving farmers with fields of hardy weeds that would no longer die when sprayed with glyphosate.

In 2011 Monsanto announced that glyphosate, had been “relied on too long by itself” and said it planned to collaborate with BASF and develop a cropping system of genetically engineered crops that would tolerate being sprayed with dicamba. It said it would introduce a new type of dicamba herbicide that would not drift far from fields where it was sprayed.

Since the introduction of the new system, complaints about dicamba drift damage have surged in several farm states, including hundreds of complaints from Illinois, Indiana, Iowa, Missouri and Arkansas.

In a report dated Nov. 1, 2017, the EPA said it had tallied 2,708 official dicamba-related crop injury investigations (as reported by state departments of agriculture). The agency said there were more than 3.6 million acres of soybeans impacted at that time. Other impacted crops were tomatoes, watermelon, cantaloupe, vineyards, pumpkins, vegetables, tobacco, residential gardens, trees and shrubs

In July 2017, the Missouri Department of Agriculture temporarily issued a “Stop Sale, Use or Removal Order,” on all dicamba products in Missouri.  The state lifted the order in September 2017.

These are some dicamba products:

On Oct. 31, 2018, the U.S. Environmental Protection Agency (EPA) announced an extension of Engenia, XtendiMax and FeXapan registrations through 2020 for “over-the-top” use in dicamba-tolerant cotton and soybean fields. EPA said it had enhanced the previous labels and put in place additional safeguards in an effort to increase the success and safe use of the product in the field.

The two-year registration is valid through Dec. 20, 2020. The EPA has stated the following provisions:

  • Only certified applicators may apply dicamba over-the-top (those working under the supervision of a certified applicator may no longer make applications)
  • Prohibit over-the-top application of dicamba on soybeans 45 days after planting or up until the R1 growth stage (first bloom), whichever comes first
  • Prohibit over-the-top application of dicamba on cotton 60 days after planting
  • For cotton, limit the number of over-the-top applications from four to two
  • For soybeans, the number of over-the-top applications remains at two
  • Applications will be allowed only from one hour after sunrise to two hours before sunset
  • In counties where endangered species may exist, the downwind buffer will remain at 110 feet and there will be a new 57-foot buffer around the other sides of the field (the 110-foot downwind buffer applies to all applications, not just in counties where endangered species may exist)
  • Enhanced tank clean-out instructions for the entire system
  • Enhanced label to improve applicator awareness on the impact of low pH on the potential volatility of dicamba
  • Label clean up and consistency to improve compliance and enforceability

Food Residues 

Just as glyphosate applications in farm fields have been found to leave residues of glyphosate on and in finished foods, such as oatmeal, breads, cereals, etc., dicamba residues are expected to leave residues in food. Farmers whose produce has been contaminated with dicamba residues via drift have expressed concerns that their products might be rejected or otherwise harmed commercially because of the residue issue.

The EPA has set tolerance levels for dicamba is several grains and for the meat of livestock that consume grains, but not for a variety of fruits and vegetables. A tolerance for dicamba in soybeans is set at 10 parts per million, for instance, in the United States, and a 2 parts per million for wheat grain. Tolerances can be seen here. 

The EPA has issued this statement regarding dicamba residues in food: “EPA performed the analysis required by the Federal Food, Drug and Cosmetic Act (FFDCA) and determined that residues on food are “safe” – meaning that there is a reasonable certainty of no harm to people, including all reasonably identifiable subpopulations, including infants and children, from dietary and all other non-occupational exposure to dicamba.”

Cancer and Hypothyroidism 

The EPA states that dicamba is not likely to be carcinogenic, but some studies have found an increased risk of cancer for users of dicamba.

See these studies regarding the human health effects of dicamba:

Pesticide Use and Incident Hypothyroidism in Pesticide Applicators in the Agricultural Health Study.  Environmental Health Perspectives (9.26.18)
“In this large prospective cohort of farmers that were occupationally exposed to pesticides, we found that ever-use of four organochlorine insecticides (aldrin, chlordane, heptachlor, and lindane), four organophosphate insecticides (coumaphos, diazinon, dichlorvos, and malathion), and three herbicides (dicamba, glyphosate, and 2,4-D) was associated with increased risk of hypothyroidism.”

Hypothyroidism and pesticide use among male private pesticide applicators in the agricultural health study. Journal of Occupational Environmental Medicine (10.1.14)
“The herbicides 2,4-D, 2,4,5-T, 2,4,5-TP, alachlor, dicamba, and petroleum oil were all associated with an increased odds of hypothyroidism”

A review of pesticide exposure and cancer incidence in the Agricultural Health Study cohort.  Environmental Heath Perspectives (8.1.10)
“We reviewed 28 studies; most of the 32 pesticides examined were not strongly associated with cancer incidence in pesticide applicators. Increased rate ratios (or odds ratios) and positive exposure–response patterns were reported for 12 pesticides currently registered in Canada and/or the United States (alachlor, aldicarb, carbaryl, chlorpyrifos, diazinon, dicamba, S-ethyl-N,N-dipropylthiocarbamate, imazethapyr, metolachlor, pendimethalin, permethrin, trifluralin).”

Cancer Incidence among Pesticide Applicators Exposed to Dicamba in the Agricultural Health Study. Environmental Health Perspectives (7.13.06)
“Exposure was not associated with overall cancer incidence nor were there strong associations with any specific type of cancer. When the reference group comprised low-exposed applicators, we observed a positive trend in risk between lifetime exposure days and lung cancer (p = 0.02), but none of the individual point estimates was significantly elevated. We also observed significant trends of increasing risk for colon cancer for both lifetime exposure days and intensity-weighted lifetime days, although these results are largely due to elevated risk at the highest exposure level.”

Non-Hodgkin’s Lymphoma and Specific Pesticide Exposures in Men: Cross-Canada Study of Pesticides and Health.  Cancer Epidemiology, Biomarkers and Prevention (11.01)
“Among individual compounds, in multivariate analyses, the risk of NHL was statistically significantly increased by exposure to the herbicides…dicamba (OR, 1.68; 95% CI, 1.00–2.81); ….In additional multivariate models, which included exposure to other major chemical classes or individual pesticides, personal antecedent cancer, a history of cancer among first-degree relatives, and exposure to mixtures containing dicamba (OR, 1.96; 95% CI, 1.40–2.75)…were significant independent predictors of an increased risk for NHL”

Litigation 

The dicamba drift damage concerns have prompted lawsuits from farmers in many U.S. states. Details on the litigation can be found here.

As Roundup cancer lawsuits surge, Monsanto fights to keep PR work secret

Posted on by Carey Gillam

As Monsanto continues to battle legal claims over alleged dangers of its widely used Roundup herbicides, the company is trying to block orders to turn over internal records about its work with public relations and strategic consulting contractors.

In a series of filings in St. Louis Circuit Court, Monsanto argues that it should not have to comply with discovery requests involving certain dealings between it and the global public relations firm FleishmanHillard, despite the fact that a special master has found Monsanto should hand those documents over. Monsanto is asserting that its communications with FleishmanHillard should be considered “privileged,” similar to attorney-client communications, and that Monsanto should not have to produce them as part of discovery to the lawyers representing the cancer patients suing Monsanto.

FleishmanHillard became the agency of record for Monsanto’s “corporate reputation work” in 2013, and its employees became deeply involved with the company, working “at Monsanto’s offices nearly every day” and gaining “access to online repositories of non-public confidential information,”  the company said. “The fact that some of these communications involve the creation of public messaging does not strip them of privilege,” Monsanto said in its court filing.

FleishmanHillard worked on two projects for Monsanto in Europe regarding re-registration of
glyphosate and worked with Monsanto lawyers on a “specific project for jury research.” The nature of the work done by the public relations firm “required privileged communications” with Monsanto’s legal counsel, the company said.

Earlier this year Monsanto owner Bayer AG said it was ending Monsanto’s relationship with FleishmanHillard after news broke that the public relations firm engaged in a Europe-wide data collection scheme for Monsanto, targeting journalists, politicians and other stakeholders to try to influence pesticide policy.

Monsanto has taken a similar position with respect to communications involving its work with corporate image management company FTI Consulting, which Monsanto hired in June 2016. “The absence of an attorney on a privileged document also does not automatically render that document susceptible to a privilege challenge,” Monsanto said in its filing.

Earlier this year, an FTI employee was caught impersonating a journalist at one of the Roundup cancer trials, trying to suggest story lines for other reporters to pursue that favored Monsanto.

The company also wants to avoid handing over documents involving its relationship with Scotts Miracle-Gro Company, which has been marketing and selling Monsanto’s Roundup lawn and garden products since 1998.

More than 40,000 cancer victims or their family members are now suing Monsanto blaming exposure to the company’s line of Roundup herbicides for their diseases, according to Bayer. The lawsuits allege that exposure to Monsanto’s herbicides caused the plaintiffs to develop non-Hodgkin lymphoma and that though Monsanto knew about the cancer risks, it intentionally did not warn consumers.

Bayer held a conference call with investors Wednesday to discuss its third quarter results and to update shareholders on the Roundup litigation.  Striking a reassuring tone, Bayer CEO Werner Baumann said that while investors might be surprised at the high number of lawsuits, it is “actually not that surprising.” He said plaintiffs’ attorneys in the United States have been spending tens of millions of dollars advertising for clients.

“This increase in the number of lawsuits does not change our conviction of the safety profile of glyphosate and is by no means a reflection of the merits of this litigation,” Baumann said. Appeals are underway after the company lost the first three trials, and the company is “constructively” engaging in mediation, according to Baumann. Bayer will only agree to a settlement that is “financially reasonable” and will bring “reasonable closure to the overall litigation,” he said.

Though the company refers to it as “glyphosate” litigation, the plaintiffs allege that their cancers were not caused by exposure to glyphosate alone, but by exposure to glyphosate-based formulated products made by Monsanto.

Many scientific studies have shown that the formulations are much more toxic than glyphosate by itself. The U.S. Environmental Protection Agency (EPA) has not required long-term safety studies on Roundup formulations throughout the 40-plus years the products have been on the market, and internal company  communications between Monsanto scientists have been obtained by plaintiffs’ attorneys in which the scientists discuss the lack of carcinogenicity testing for Roundup products.

Multiple trials that were scheduled for this fall in the St. Louis, Missouri area have been delayed until next year.

Trial in Monsanto’s Hometown Set for August After $2 Billion Verdict

By Carey Gillam

After three stunning courtroom losses in California, the legal battle over the safety of Monsanto’s top-selling Roundup herbicide is headed for the company’s hometown, where corporate officials can be forced to appear on the witness stand, and legal precedence shows a history of anti-corporate judgments.

“The things that have gone on here, I want St. Louis juries to hear this stuff.”

Sharlean Gordon, a cancer-stricken woman in her 50s, is the next plaintiff currently set for trial. Gordon v. Monsanto starts Aug. 19 in St. Louis County Circuit Court, located just a few miles from the St. Louis, Missouri-area campus that was the company’s longtime world headquarters until Bayer bought Monsanto last June. The case was filed in July 2017 on behalf of more than 75 plaintiffs and Gordon is the first of that group to go to trial.

According to the complaint, Gordon purchased and used Roundup for at least 15 continuous years through approximately 2017 and was diagnosed with a form of non-Hodgkin lymphoma in 2006. Gordon has gone through two stem cell transplants and spent a year in a nursing home at one point in her treatment.

She is so debilitated that it is difficult for her to be mobile.

Her case, like that of the thousands of others filed around the United States, alleges use of Monsanto’s glyphosate-based herbicides caused her to develop non-Hodgkin lymphoma.

“She’s been through hell,” St. Louis attorney Eric Holland, one of the legal team members representing Gordon, told EHN. “She’s horribly injured. The human toll here is tremendous. I think Sharlean is really going to put a face on what Monsanto’s done to people.”

Holland said the hardest part about preparing for trial is determining what evidence to present to the jury within the three-week time span that the judge has set for the trial.

“This evidence against them, their conduct, is the most outrageous I’ve seen in my 30 years of doing this,” Holland said. “The things that have gone on here, I want St. Louis juries to hear this stuff.”

That Gordon trial will be followed by a September 9 trial also in St. Louis County in a case brought by plaintiffs Maurice Cohen and Burrell Lamb.

Monsanto’s deep roots in the community, including a large employment base and generous charitable donations throughout the area, could favor its chances with local jurors.

But on the flip side, St. Louis is regarded in legal circles as one the most favorable places for plaintiffs to bring lawsuits against corporations and there is a long history of large verdicts against major companies. St. Louis City Court is generally considered the most favorable but St. Louis County is also desired by plaintiffs’ attorneys.

The approach of the August and September trials comes on the heels of a stunning $2 billion verdict issued against Monsanto May 13. In that case, a jury in Oakland, California, awarded married couple Alva and Alberta Pilliod, who both suffer from cancer, $55 million in compensatory damages and $1 billion each in punitive damages.

The jury found that Monsanto has spent years covering up evidence that its herbicide causes cancer.

That verdict came only a little more than a month after a San Francisco jury ordered Monsanto to pay $80 million in damages to Edwin Hardeman, who also developed non-Hodgkin lymphoma after using Roundup. And last summer, a jury ordered Monsanto to pay $289 million to groundskeeper Dewayne “Lee” Johnson who received a terminal cancer diagnosis after using Monsanto herbicides in his job.

Aimee Wagstaff, who was co-lead counsel for Hardeman, is set to try the Gordon case in St. Louis with Holland. Wagstaff said she plans to subpoena several Monsanto scientists to appear on the witness stand to answer questions directly in front of a jury.

She and the other attorneys trying the California cases were not able to force Monsanto employees to testify live because of the distance. The law provides that witnesses cannot be compelled to travel more than 100 miles or out of state from where they live or work.

Mediation meeting

The trial losses have left Monsanto and its German owner Bayer AG under siege. Angry investors have pushed share prices to the lowest levels in roughly seven years, erasing more than 40 percent of Bayer’s market value.

And some investors are calling for Bayer CEO Werner Baumann to be ousted for championing the Monsanto acquisition, which closed in June of last year just as the first trial was getting underway.

Bayer maintains that there is no valid evidence of cancer causation associated with Monsanto’s herbicides, and says it believes it will win on appeal. But U.S. District Judge Vince Chhabria has ordered Bayer to begin mediation talks aimed at potentially settling the sprawling mass of lawsuits that includes roughly 13,400 plaintiffs in the United States alone.

All the plaintiffs are cancer victims or their family members and all allege Monsanto engaged in a range of deceptive tactics to hide the risks of its herbicides, including manipulating the scientific record with ghostwritten studies, colluding with regulators, and using outside individuals and organizations to promote the safety of its products while making sure they falsely appeared to be acting independently of the company.

A May 22 hearing is being held in part to define details of the mediation process. Bayer has indicated that it will comply with the order, but may not yet be ready to consider settling the litigation despite the courtroom losses.

Meanwhile, the litigation that originated in the United States has crossed the border into Canada where a Saskatchewan farmer is leading a class action lawsuit against Bayer and Monsanto making allegations that mirror those in the U.S. lawsuits.

“The Queen of Roundup”

Elaine Stevick of Petaluma, California was supposed to be the next in line to take on Monsanto at trial.

But in his order of mediation, Judge Chhabria also vacated her May 20 trial date. A new trial date is to be discussed at the hearing on Wednesday.

Stevick and her husband Christopher Stevick sued Monsanto in April of 2016 and said in an interview that they are eager to get their chance to confront the company over the devastating damage they say Elaine’s use of Roundup has done to her health.

She was diagnosed in December 2014 at the age of 63 with multiple brain tumors due to a type of non-Hodgkin lymphoma called central nervous system lymphoma (CNSL). Alberta Pilliod, who just won the most recent trial, also had a CNSL brain tumor.

The couple purchased an old Victorian home and overgrown property in 1990 and while Christopher worked on renovating the interior of the house, Elaine’s job was to spray weed killer over the weeds and wild onions that the couple said took over a good portion of the property.

She sprayed multiple times a year until she was diagnosed with cancer. She never wore gloves or other protective clothing because believed it to be as safe as advertised, she said.

Stevick is currently in remission but nearly died at one point in her treatment, Christopher Stevick said.

“I called her the ‘queen of Roundup’ because she was always walking around spraying the stuff,” he told EHN.

The couple attended parts of both the Pilliod and Hardeman trials, and said they are grateful the truth about Monsanto’s actions to hide the risks are coming into the public spotlight. And they want to see Bayer and Monsanto start warning users about the cancer risks of Roundup and other glyphosate-based herbicides.

“We want the companies to take responsibility for warning people—even if there is a chance that something would be harmful or hazardous for them, people should be warned,” Elaine Stevick told EHN.

Who Is Paying for Monsanto’s Crimes? We Are

The chickens are coming home to roost, as they say in farm country.

For the second time in less than eight months a US jury has found that decades of scientific evidence demonstrates a clear cancer connection to Monsanto’s line of top-selling Roundup herbicides, which are used widely by consumers and farmers. Twice now jurors have additionally determined that the company’s own internal records show Monsanto has intentionally manipulated the public record to hide the cancer risks. Both juries found punitive damages were warranted because the company’s cover-up of cancer risks was so egregious.

The juries saw evidence that Monsanto has ghost-written scientific papers, tried to silence scientists, scuttled independent government testing and cozied up to regulators for favorable safety reviews of glyphosate, the active ingredient in Roundup.

Even the US district judge Vince Chhabria, who oversaw the San Francisco trial that concluded Wednesday with an $80.2m damage award, had harsh words for Monsanto. Chhabria said there were “large swaths of evidence” showing that the company’s herbicides could cause cancer. He also said there was “a great deal of evidence that Monsanto has not taken a responsible, objective approach to the safety of its product … and does not particularly care whether its product is in fact giving people cancer, focusing instead on manipulating public opinion and undermining anyone who raises genuine and legitimate concerns about the issue.”

Monsanto’s new owner, the German pharmaceutical company Bayer, asserts that the juries and judges are wrong; the evidence of a cancer risk is invalid; the evidence of bad corporate conduct is misunderstood and out of context; and that the company will ultimately prevail.

Meanwhile, Monsanto critics are celebrating the wins and counting on more as a third trial got underway this week and 11,000 additional plaintiffs await their turn. As well, a growing number of communities and businesses are backing away from use of Monsanto’s herbicides. And investors are punishing Bayer, pushing share prices to a seven-year low on Thursday.

Susquehanna Financial Group analyst Tom Claps has warned shareholders to brace for a global settlement of between $2.5bn and $4.5bn.

“We don’t believe [Monsanto] will lose every single trial, but we do believe that they could lose a significant majority,” he told the Guardian.

Following the recent courtroom victories, some have cheered the notion that Monsanto is finally being made to pay for alleged wrongdoing. But by selling to Bayer last summer for $63bn just before the Roundup cancer lawsuits started going to trial, Monsanto executives were able to walk away from the legal mess with riches. The Monsanto chairman Hugh Grant’s exit package allowed him to pocket $32m, for instance.

Amid the uproar of the courtroom scuffles, a larger issue looms: Monsanto’s push to make use of glyphosate herbicides so pervasive that traces are commonly found in our food and even our bodily fluids, is just one example of how several corporate giants are creating lasting human health and environmental woes around the world. Monsanto and its brethren have targeted farmers in particular as a critical market for their herbicides, fungicides and insecticides, and now many farmers around the world believe they cannot farm without them.

Studies show that along with promoting illness and disease in people, these pesticides pushed by Bayer and Monsanto, DowDuPont and other corporate players, are endangering wildlife, soil health, water quality and the long-term sustainability of food production. Yet regulators have allowed these corporations to combine forces, making them ever more powerful and more able to direct public policies that favor their interests.

The Massachusetts senator Elizabeth Warren this week called for taking back some of that power. She announced on Wednesday a plan to break up big agribusinesses and work against the type of corporate capture of Washington we have seen in recent years.

It’s a solid step in the right direction. But it cannot undo the suffering of cancer victims, nor easily transform a deeply contaminated landscape to create a healthier future and unleash us from the chains of a pesticide-dependent agricultural system.

And while Bayer may dole out a few billion dollars in damages, who is really being made to pay?

We all are.

Weedkiller ‘Raises Risk of Non-Hodgkin Lymphoma by 41%’

Study says evidence ‘supports link’ between exposure to glyphosate and increased risk

This article was originally published in the Guardian.

By Carey Gillam

A broad new scientific analysis of the cancer-causing potential of glyphosate herbicides, the most widely used weedkilling products in the world, has found that people with high exposures to the popular pesticides have a 41% increased risk of developing a type of cancer called non-Hodgkin lymphoma.

The evidence “supports a compelling link” between exposures to glyphosate-based herbicides and increased risk for non-Hodgkin lymphoma (NHL), the authors concluded, though they said the specific numerical risk estimates should be interpreted with caution.

The findings by five US scientists contradict the US Environmental Protection Agency’s (EPA) assurances of safety over the weed killer and come as regulators in several countries consider limiting the use of glyphosate-based products in farming.

Monsanto and its German owner Bayer AG face more than 9,000 lawsuits in the US brought by people suffering from NHL who blame Monsanto’s glyphosate-based herbicides for their diseases. The first plaintiff to go to trial won a unanimous jury verdict against Monsanto in August, a verdict the company is appealing. The next trial, involving a separate plaintiff, is set to begin on 25 February, and several more trials are set for this year and into 2020.

Monsanto maintains there is no legitimate scientific research showing a definitive association between glyphosate and NHL or any type of cancer. Company officials say the EPA’s finding that glyphosate is “not likely” to cause cancer is backed by hundreds of studies finding no such connection.

The company claims the scientists with the International Agency for Research on Cancer (IARC) who classified glyphosate as a probable human carcinogen in 2015 engaged in improper conduct and failed to give adequate weight to several important studies.

But the new analysis could potentially complicate Monsanto’s defense of its top-selling herbicide. Three of the study authors were tapped by the EPA as board members for a 2016 scientific advisory panel on glyphosate. The new paper was published by the journal Mutation Research /Reviews in Mutation Research, whose editor in chief is EPA scientist David DeMarini.

The study’s authors say their meta-analysis is distinctive from previous assessments. “This paper makes a stronger case than previous meta-analyses that there is evidence of an increased risk of NHL due to glyphosate exposure,” said co-author Lianne Sheppard, a professor in the Environmental and Occupational Health Sciences department at the University of Washington. “From a population health point of view there are some real concerns.”

Sheppard was one of the scientific advisers to the EPA on glyphosate and was among a group of those advisers who told the EPA that it failed to follow proper scientific protocols in determining that glyphosate was not likely to cause cancer. “It was wrong,” Sheppard said of the EPA glyphosate assessment. “It was pretty obvious they didn’t follow their own rules. “Is there evidence that it is carcinogenic? The answer is yes.”

An EPA spokesperson said: “We are reviewing the study.” Bayer, which bought Monsanto in the summer of 2018, did not respond to a request for comment about the study.

A Bayer statement on glyphosate cites the EPA assessment and says that glyphosate herbicides have been “extensively evaluated” and are proven to be a “safe and efficient weed control tool”.

The study authors said their new meta-analysis evaluated all published human studies, including a 2018 updated government-funded study known as the Agricultural Health Study (AHS). Monsanto has cited the updated AHS study as proving that there is no tie between glyphosate and NHL. In conducting the new meta-analysis, the researchers said they focused on the highest exposed group in each study because those individuals would be most likely to have an elevated risk if in fact glyphosate herbicides cause NHL.

Looking only at individuals with real-world high exposures to the pesticide makes it is less likely that confounding factors may skew results, the authors said. In essence – if there is no true connection between the chemical and cancer then even highly exposed individuals should not develop cancer at significant rates.

In addition to looking at the human studies, the researchers also looked at other types of glyphosate studies, including many conducted on animals.

“Together, all of the meta-analyses conducted to date, including our own, consistently report the same key finding: exposure to GBHs are associated with an increased risk of NHL,” the scientists concluded.

David Savitz, professor of epidemiology in the Brown University School of Public Health, said the work was “well conducted” but lacking “fundamentally new information”.

“I would suggest it sustains the concern and need for assessment but doesn’t put the question to rest in any definitive sense,” Savitz said.

In a statement Bayer later said, “[The study] does not provide new epidemiology data; instead, it is a statistical manipulation that is at odds with the extensive body of science, 40 years of real world experience and the conclusions of regulators.”

It added: “[The study] provides no scientifically valid evidence that contradicts the conclusions of the extensive body of science demonstrating that glyphosate-based herbicides are not carcinogenic.”

Moms Exposed to Monsanto Weed Killer Means Bad Outcomes for Babies

Posted on by Carey Gillam

Concerns about the world’s most widely used herbicide are taking a new twist as researchers unveil data that indicates pervasive use of Monsanto Co.’s weed killer could be linked to pregnancy problems.

Researchers looking at exposure to the herbicide known as glyphosate, the key ingredient in Monsanto’s Roundup branded herbicides, said they tested and tracked 69 expectant mothers and found that the presence of glyphosate levels in their bodily fluids correlated with unfavorable birth outcomes. The research is still in preliminary stages and the sample size is small, but the team is scheduled to present their findings on Thursday at a conference put on by the Children’s Environmental Health Network (CEHN) in Washington, D.C.

“This is a huge issue,” said Paul Winchester, medical director of the neonatal intensive care unit at the Franciscan St. Francis Health system and professor of clinical pediatrics at Riley Hospital for Children in Indianapolis, Indiana. He said this is the first U.S. study to demonstrate glyphosate is present in pregnant women. “Everyone should be concerned about this.”

Glyphosate is a popular agricultural pesticide, used widely in farming operations around the world. It’s commonly sprayed directly on many food crops and those used for livestock feed. But it has become the subject of hot debate over the last few years because of research that links the herbicide to types of cancer and other health ailments. Monsanto is being sued by hundreds of people who claim they or their loved ones developed non-Hodgkin lymphoma because of exposure to glyphosate-based Roundup. Monsanto, the EPA and other regulatory bodies, say evidence of carcinogenicity is lacking and the chemical is among the safest of all pesticides used in food production. But documents discovered in the course of the litigation indicate the company may have manipulated scientific research to hide evidence of harm.

The team that presented their report Wednesday included scientists who have long been skeptical of Monsanto’s products as well as medical researchers who have come to have concerns about glyphosate and other pesticides through their study of pediatric health problems.

Winchester, who led the urine sampling study, said his look at glyphosate and pregnant women is in very early stages and he and co-researchers are hoping to launch a much larger project later this year. The preliminary work detected glyphosate in the urine of 63 of 69 (91%) pregnant women receiving prenatal care through an Indiana obstetric practice. Researchers collected the data over two years, from 2015-2016, and found that higher glyphosate levels in women correlated with significantly shorter pregnancies and with lower adjusted birth weights.

Correlation does not prove causation. Still, the findings are worrisome because low birth weights and shortened gestation are seen as risk factors for many health and/or neurodevelopmental problems over the course of an individual’s life. Low birth-weight babies are more likely to have diabetes, heart disease, high blood pressure, and to be obese, research shows.

People can be exposed to glyphosate through food and through association with farming operations that spray glyphosate on corn and soybean production fields. Both soy and corn, along with several other crops, have been genetically engineered to tolerate direct application of glyphosate. Farmers often also use glyphosate directly on wheat, oats and other non-genetically engineered crops shortly before harvest, leading to residues in grain-based food products.

Glyphosate use has climbed sharply over the last two decades with the rise of genetically engineered crops and in connection with the subsequent spread of glyphosate-resistant weeds. Dr. Charles Benbrook, one of the scheduled presenters at the CEHN conference, projects that by 2020, “more acres of cropland in the Midwest will harbor three or more glyphosate-resistant weeds than one or none.” Farmers have been trying to fight the resistant weeds with more glyphosate and other chemicals. New crops engineered to tolerate 2,4-D and dicamba herbicides mixed with glyphosate are being rolled out now. Industry data indicates herbicide use is expected to continue to climb, making it ever more critical for scientists and medical professional to get a handle on exposure levels and impacts on reproductive health, the team said in their presentation.

Winchester has been conducting research into pesticide exposures and impacts on pregnant women for many years, including in-depth work on atrazine, another herbicide popular with farmers. He said he was surprised to see such a high percentage of women tested showing glyphosate in their urine. He said much more research on glyphosate impacts is needed, and more data is needed on levels of exposure through food. He was sharply critical of the U.S. government, which routinely skips testing for glyphosate residues in food even though regulatory agencies test thousands of food products each year for residues of other types of pesticides, including atrazine.

He and the other researchers are calling on the Centers for Disease Control to include glyphosate and its primary metabolite, aminomethylphosphonic acid (AMPA) in biomonitoring work it does to track levels of pesticides and other chemicals in urine and blood.

“Is this level of exposure safe or not? We’ve been told it is, but exposures haven’t been measured,” Winchester said. “It’s mind-boggling.”
