Dicamba litigation against Bayer, BASF poised to explode, lawyers say

Print Email Share Tweet

Thousands of farmers from multiple states are expected to join mass tort litigation pending in federal court over claims that weed-killing products developed by the former Monsanto Co. and other chemical companies are destroying and contaminating crops, including organic production, a group of lawyers and farmers said on Wednesday.

The number of farmers seeking legal representation to file suit against Monsanto and BASF has surged over the last week and a half after a staggering $265 million jury award to a Missouri peach farmer who alleged the two companies were to blame for the loss of his livelihood, according to Joseph Peiffer of the Peiffer Wolf Carr & Kane law firm. Peiffer said more than 2,000 farmers are likely to become plaintiffs.

There are already over 100 farmers making claims against the companies that have been combined in multidistrict litigation in U.S. District Court in Cape Girardeau, Missouri.

Earlier this month the bellwether trial for that litigation ended with a unanimous jury awarding the family-owned Bader Farms $15 million in compensatory damages and $250 million in punitive damages, to be paid by  Bayer AG, the German company that bought Monsanto in 2018, and by BASF.  The jury concluded that  Monsanto and BASF conspired in actions they knew would lead to widespread crop damage because they expected it would increase their own profits.

We now have the road map to get justice for dicamba victims.  The Bader verdict in Missouri sent a clear signal that you can’t profit off of hurting innocent farmers and get away with it,” said Peiffer.  “The crop damage research and increasing farmer complaints forecast a much bigger problem than Monsanto/Bayer and BASF want to admit.”

U.S. Right to Know asked the Environmental Protection Agency (EPA), which approved the dicamba herbicides despite scientific evidence of the risks, to provide a national tally for the total number of dicamba drift complaints. But while the EPA said it was taking the reports “very seriously,” it declined to provide a tally and said it was up to state agencies to handle such complaints.

The EPA also indicated it was not certain the damage reported by farmers was, in fact, due to dicamba.

“The underlying causes of the various damage incidents are not yet clear, as on-going investigations have yet to be concluded,” said an EPA spokesperson. “But EPA is reviewing all available information carefully.

“Ticking Time Bomb”

Just as Monsanto and Bayer have been confronted with damning internal documents in losing three trials over claims Monsanto’s glyphosate-based herbicides cause cancer, there are many internal corporate documents discovered in the dicamba litigation that helped convince the jury of the company’s guilt, according to Bader Farms attorney Bill Randles.

Randles has obtained hundreds of internal Monsanto and BASF corporate records demonstrating the companies were aware of the harm their products would create even as they publicly professed the opposite. He said one BASF document referred to dicamba damage complaints as a “ticking time bomb” that “has finally exploded.”

Bader and the other farmers allege that Monsanto was negligent in rolling out genetically engineered cotton and soybeans that could survive being sprayed with dicamba herbicides because it was known that using the crops and chemicals as designed would lead to damage.

Dicamba has been used by farmers since the 1960s but with limits that took into account the chemical’s propensity to drift far from where it was sprayed. When Monsanto’s popular glyphosate weed killing products such as Roundup started losing effectiveness due to widespread weed resistance, Monsanto decided to launch a dicamba cropping system similar to its popular Roundup Ready system, which paired glyphosate-tolerant seeds with glyphosate herbicides.

Farmers buying the new genetically engineered dicamba-tolerant seeds could more easily treat stubborn weeds by spraying  entire fields with dicamba, even during warm growing months, without harming their crops, according to Monsanto, which announced a  dicamba collaboration with BASF in 2011. The companies said their new dicamba herbicides would be less volatile and less prone to drift than old formulations of dicamba. But they refused to allow for independent scientific testing.

The EPA approved the use of Monsanto’s dicamba herbicide “XtendiMax” in 2016. BASF developed its own dicamba herbicide that it calls Engenia. Both XtendiMax and Engenia were first sold in the United States in 2017.

DuPont also introduced a dicamba herbicide and could also face multiple farmer lawsuits, according to the plaintiffs’ lawyers.

In their legal claims,  farmers allege that they have experienced damage both from the drift of old versions of dicamba and drifting newer versions as well. The farmers claim that the companies hoped fears of drift damage would force farmers to buy the special GMO dicamba-tolerant seeds in order to protect their cotton and soybean fields.

Farmers growing other types of crops have been without any means to protect their fields.

North Carolina farmer Marty Harper, who grows about 4,000 acres of tobacco as well as peanuts, cotton, corn, soybeans, wheat, and sweet potatoes, said dicamba-related damage to his tobacco fields exceeds  $200,000.  He said part of his peanut crop has also been damaged.

More than 2,700 farms have suffered dicamba damage, according to University of Missouri crop science professor Kevin Bradley.

Dicamba Fact Sheet

Print Email Share Tweet

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.

Chemicals on Our Food: When “Safe” May Not Really Be Safe

Scientific scrutiny of pesticide residue in food grows; regulatory protections questioned

This article was originally published in Environmental Health News.

By Carey Gillam

Weed killers in wheat crackers and cereals, insecticides in apple juice and a mix of multiple pesticides in spinach, string beans and other veggies – all are part of the daily diets of many Americans. For decades, federal officials have declared tiny traces of these contaminants to be safe. But a new wave of scientific scrutiny is challenging those assertions.

Though many consumers might not be aware of it, every year, government scientists document how hundreds of chemicals used by farmers on their fields and crops leave residues in widely consumed foods. More than 75 percent of fruits and more than 50 percent of vegetables sampled carried pesticides residues in the latest sampling reported by the Food and Drug Administration. Even residues of the tightly restricted bug-killing chemical DDT are found in food, along with a range of other pesticides known by scientists to be linked to a range of illnesses and disease. The pesticide endosulfan, banned worldwide because of evidence that it can cause neurological and reproductive problems, was also found in food samples, the FDA report said.

U.S. regulators and the companies that sell the chemicals to farmers insist that the pesticide residues pose no threat to human health. Most residue levels found in food fall within legal “tolerance” levels set by the Environmental Protection Agency (EPA), regulators say.

“Americans depend on the FDA to ensure the safety of their families and the foods they eat,” FDA Commissioner Scott Gottlieb said in a press release accompanying the agency’s Oct. 1 release of its residue report. “Like other recent reports, the results show that overall levels of pesticide chemical residues are below the Environmental Protection Agency’s tolerances, and therefore don’t pose a risk to consumers.”

The EPA is so confident that traces of pesticides in food are safe that the agency has granted multiple chemical company requests for increases in the allowed tolerances, effectively providing a legal basis for higher levels of pesticide residues to be allowed in American food.

But recent scientific studies have prompted many scientists to warn that years of promises of safety may be wrong. While no one is expected to drop dead from eating a bowl of cereal containing pesticide residues, repeated low level exposures to trace amounts of pesticides in the diet could be contributing to a range of health problems, particularly for children, scientists say.

“There are probably many other health effects; we just haven’t studied them”

A team of Harvard scientists published a commentary in October stating that more research about potential links between disease and consumption of pesticide residues is “urgently needed” as more than 90 percent of the U.S. population has pesticide residues in their urine and blood. The primary route of exposure to these pesticides is through the food people eat, the Harvard research team said.

Several additional Harvard-affiliated scientists published a study earlier this year of women who were trying to get pregnant. The findings suggested that dietary pesticide exposure within a “typical” range was associated both with problems women had getting pregnant and delivering live babies, the scientists said.

“Clearly the current tolerance levels protect us from acute toxicity. The problem is that it is not clear to what extent long-term low-level exposure to pesticide residues through food may or may not be health hazards,” said Dr. Jorge Chavarro, associate professor of the Departments of Nutrition and Epidemiology at the Harvard T.H. Chan School of Public Health, and one of the study authors.

“Exposure to pesticide residues through diet is associated [with] some reproductive outcomes including semen quality and greater risk of pregnancy loss among women undergoing infertility treatments. There are probably many other health effects; we just haven’t studied them sufficiently to make an adequate risk assessment,” Chavarro said.

Toxicologist Linda Birnbaum, who directs the U.S. National Institute of Environmental Health Sciences (NIEHS), has also raised concerns about pesticide dangers through exposures once assumed to be safe. Last year she called for “an overall reduction in the use of agricultural pesticides” due to multiple concerns for human health, stating that “existing US regulations have not kept pace with scientific advances showing that widely used chemicals cause serious health problems at levels previously assumed to be safe.”

In an interview Birnbaum said that pesticide residues in food and water are among the types of exposures that need greater regulatory scrutiny.

“Do I think that levels that are currently set are safe? Probably not,” said Birnbaum. “We have people of different susceptibility, whether because of their own genetics, or their age, whatever may make them more susceptible to these things,” she said.

“While we look at chemicals one at a time, there is a lot of evidence for things acting in a synergistic fashion. A lot of our standard testing protocols, many that were developed 40 to 50 years ago, are not asking the questions we should be asking,” she added.

Legal doesn’t mean safe

Other recent scientific papers also point to troubling findings. One by a group of international scientists published in May found glyphosate herbicide at doses currently considered “safe” are capable of causing health problems before the onset of puberty. More research is needed to understand potential risks to children, the study authors said.

And in a paper published Oct. 22 in JAMA Internal Medicine, French researchers said that when looking at pesticide residue links to cancer in a study of the diets of more than 68,000 people, they found indications that consumption of organic foods, which are less likely to carry synthetic pesticide residues than foods made with conventionally grown crops, was associated with a reduced risk of cancer.

A 2009 paper published by a Harvard researcher and two FDA scientists found 19 out of 100 food samples that children commonly consumed contained at least one insecticide known to be a neurotoxin. The foods the researchers looked at were fresh vegetables, fruits and juices. Since then, evidence has grown about the harmful human health impacts of insecticides, in particular.

Unacceptable levels

“A number of current legal standards for pesticides in food and water do not fully protect public health, and do not reflect the latest science,” said Olga Naidenko, senior science advisor to the non-profit Environmental Working Group, which has issued several reports looking at potential dangers of pesticides in food and water. “Legal does not necessarily reflect ‘safe,'” she said.

One example of how regulatory assurances of safety have been found lacking when it comes to pesticide residues is the case of an insecticide known as chlorpyrifos. Marketed by Dow Chemical, which became the DowDuPont company in 2017, chlorpyrifos is applied to more than 30 percent of apples, asparagus, walnuts, onions, grapes, broccoli, cherries and cauliflower grown in the U.S. and is commonly found on foods consumed by children. The EPA has said for years that exposures below the legal tolerances it set were nothing to worry about.

Yet scientific research in recent years has demonstrated an association between chlorpyrifos exposure and cognitive deficits in children. The evidence of harm to young developing brains is so strong that the EPA in 2015 said that it “cannot find that any current tolerances are safe.”

The EPA said that because of unacceptable levels of the insecticide in food and drinking water it planned to ban the pesticide from agricultural use. But pressure from Dow and chemical industry lobbyists have kept the chemical in wide use on American farms. The FDA’s recent report found it the 11th most prevalent pesticides in U.S. foods out of hundreds included in the testing.

A federal court in August said that the Trump Administration was endangering public health by keeping chlorpyrifos in use for agricultural food production. The court cited “scientific evidence that its residue on food causes neurodevelopmental damage to children” and ordered the EPA to revoke all tolerances and ban the chemical from the market. The EPA has yet to act on that order, and is seeking a rehearing before the full 9th Circuit Court of Appeals.

When asked how to explain its changing positions on chlorpyrifos, an agency spokesman said that the EPA “plans to continue to review the science addressing neurodevelopmental effects” of the chemical.

The fact that it is still in wide use frustrates and angers physicians who specialize in child health and leaves them wondering what other pesticide exposures in food might be doing to people.

“The bottom line is that the biggest public health concerns for chlorpyrifos are from its presence in foods,” said Dr. Bradley Peterson director of the Institute for the Developing Mind at the Children’s Hospital of Los Angeles. “Even small exposures can potentially have harmful effects.”

The EPA decision to continue to allow chlorpyrifos into American diets is “emblematic of a broader dismissal of scientific evidence” that challenges human health as well as scientific integrity, according to Dr. Leonardo Trasande, who directs the Division of Environmental Pediatrics within the Department of Pediatrics at New York University’s Langone Health.

Epidemiologist Philip Landrigan, director of Boston College’s Global Public Health initiative, and a former scientist with the U.S. Centers for Disease Control, is advocating for a ban on all organophosphates, a class of insecticides that includes chlorpyrifos, because of the danger they pose to children.

“Children are exquisitely vulnerable to these chemicals,” said Landrigan. “This is about protecting kids.”

Increased tolerances at industry request

The Federal Food, Drug, and Cosmetic Act authorizes the EPA to regulate the use of pesticides on foods according to specific statutory standards and grants the EPA a limited authority to establish tolerances for pesticides meeting statutory qualifications.

Tolerances vary from food to food and pesticide to pesticide, so an apple might legally carry more of a certain type of insecticide residue than a plum, for instance. The tolerances also vary from country to country, so what the U.S. sets as a legal tolerance for residues of a pesticide on a particular food can – and often is – much different than limits set in other countries. As part of the setting of those tolerances, regulators examine data showing how much residue persists after a pesticide is used as intended on a crop, and they undertake the dietary risk assessments to confirm that the levels of pesticide residues don’t pose human health concerns.

The agency says that it accounts for the fact that the diets of infants and children may be quite different from those of adults and that they consume more food for their size than adults. The EPA also says it combines information about routes of pesticide exposure – food, drinking water residential uses – with information about the toxicity of each pesticide to determine the potential risks posed by the pesticide residues. The agency says if the risks are “unacceptable,” it will not approve the tolerances.

The EPA also says that when it makes tolerance decisions, it “seeks to harmonize U.S. tolerances with international standards whenever possible, consistent with U.S. food safety standards and agricultural practices.”

Monsanto, which became of unit of Bayer AG earlier this year, has successfully asked the EPA to expand the levels of glyphosate residues allowed in several foods, including in wheat and oats.

In 1993, for example, the EPA had a tolerance for glyphosate in oats at 0.1 parts per million (ppm) but in 1996 Monsanto asked EPA to raise the tolerance to 20 ppm and the EPA did as asked. In 2008, at Monsanto’s suggestion, the EPA again looked to raise the tolerance for glyphosate in oats, this time to 30 ppm.

At that time, it also said it would raise the tolerance for glyphosate in barley from 20 ppm to 30 ppm, raise the tolerance in field corn from 1 to 5 ppm and raise the tolerance of glyphosate residue in wheat from 5 ppm to 30 ppm, a 500 percent increase. The 30 ppm for wheat is matched by more than 60 other countries, but is well above the tolerances allowed in more than 50 countries, according to an international tolerance database established with EPA funding and maintained now by a private government affairs consulting group.

“The Agency has determined that the increased tolerances are safe, i.e, there is a reasonable certainty that no harm will result from aggregate exposure to the pesticide chemical residue,” the EPA stated in the May 21, 2008 Federal Register.

“All these statements from EPA – trust us it’s safe. But the truth is we have no idea if it actually is safe,” said Dr. Bruce Lanphear, a clinician scientist at the Child & Family Research Institute, BC Children’s Hospital, and a professor in the faculty of health sciences at Simon Fraser University in Vancouver, British Columbia. Lanphear said that while regulators assume toxic effects increase with dose, scientific evidence shows that some chemicals are most toxic at the lowest levels of exposure. Protecting public health will require rethinking basic assumptions about how agencies regulate chemicals, he argued in a paper published last year.

In recent years both Monsanto and Dow have received new tolerance levels for the pesticides dicamba and 2,4-D on food as well.

Raising tolerances allows farmers to use pesticides in various ways that may leave more residues, but that doesn’t threaten human health, according to Monsanto. In a blog posted last year, Monsanto scientist Dan Goldstein asserted the safety of pesticide residues in food generally and of glyphosate in particular. Even when they exceed the regulatory legal limits, pesticide residues are so minuscule they pose no danger, according to Goldstein, who posted the blog before he retired from Monsanto this year.

About half of foods sampled contained traces of pesticides

Amid the scientific concerns, the most recent FDA data on pesticide residues in food found that roughly half of the foods the agency sampled contained traces of insecticides, herbicides, fungicides and other toxic chemicals used by farmers in growing hundreds of different foods.

More than 90 percent of apple juices sampled were found to contain pesticides. The FDA also reported that more than 60 percent of cantaloupe carried residues. Overall, 79 percent of American fruits and 52 percent of vegetables contained residues of various pesticides – many known by scientists to be linked to a range of illnesses and disease. Pesticides were also found in soy, corn, oat and wheat products, and finished foods like cereals, crackers and macaroni.

The FDA analysis “almost exclusively” is focused on products that are not labeled as organic, according to FDA spokesman Peter Cassell.

The FDA downplays the percentage of foods containing pesticide residues and focuses on the percentage of samples for which there is no violation of the tolerance levels. In its most recent report, the FDA said that more than “99% of domestic and 90% of import human foods were compliant with federal standards.”

The report marked the agency’s launch of testing for the weed killer glyphosate in foods. The Government Accountability Office said in 2014 that both the FDA and the U.S. Department of Agriculture should start regularly testing foods for glyphosate. The FDA did only limited tests looking for glyphosate residues, however, sampling corn and soy and milk and eggs for the weed killer, the agency said. No residues of glyphosate were found in milk or eggs, but residues were found in 63.1 percent of the corn samples and 67 percent of the soybean samples, according to FDA data.

The agency did not disclose findings by one of its chemists of glyphosate in oatmeal and honey products, even though the FDA chemist made his findings known to supervisors and other scientists outside the agency.

Cassell said the honey and oatmeal findings were not part of the agency’s assignment.

Overall, the new FDA report covered sampling done from Oct. 1, 2015, through Sept. 30, 2016, and included analysis of 7,413 samples of food examined as part of the FDA’s “pesticide monitoring program.” Most of the samples were of food to be eaten by people, but 467 samples were of animal food. The agency said that pesticide residues were found in 47.1 percent of the samples of food for people produced domestically and 49.3 percent of food imported from other countries destined for consumer meals. Animal food products were similar, with pesticide residues found in 57 percent of the domestic samples and 45.3 percent of imported foods for animals.

Many imported food samples showed residues of pesticides high enough to break the legal limits, the FDA said. Nearly 20 percent of imported grain and grain product samples showed illegally high levels of pesticides, for example.

Internal FDA Emails: Weedkiller Found in Granola and Crackers

Print Email Share Tweet

This article was originally published in the Guardian.

By Carey Gillam

US government scientists have detected a weedkiller linked to cancer in an array of commonly consumed foods, emails obtained through a freedom of information request show.

The Food and Drug Administration (FDA) has been testing food samples for residues of glyphosate, the active ingredient in hundreds of widely used herbicide products, for two years, but has not yet released any official results.

But the internal documents obtained by the Guardian show the FDA has had trouble finding any food that does not carry traces of the pesticide.

“I have brought wheat crackers, granola cereal and corn meal from home and there’s a fair amount in all of them,” FDA chemist Richard Thompson wrote to colleagues in an email last year regarding glyphosate. Thompson, who is based in an FDA regional laboratory in Arkansas, wrote that broccoli was the only food he had “on hand” that he found to be glyphosate-free.

That internal FDA email, dated January 2017, is part of a string of FDA communications that detail agency efforts to ascertain how much of the popular weedkiller is showing up in American food. The tests mark the agency’s first-ever such examination.

“People care about what contaminants are in their food. If there is scientific information about these residues in the food, the FDA should release it,” said Tracey Woodruff, a professor in the University of California San Francisco School of Medicine. “It helps people make informed decisions. Taxpayers paid for the government to do this work, they should get to see the information.”

The FDA is charged with annually testing food samples for pesticide residues to monitor for illegally high residue levels. The fact that the agency only recently started testing for glyphosate, a chemical that has been used for over 40 years in food production, has led to criticism from consumer groups and the Government Accountability Office (GAO). Calls for testing grew after the International Agency for Research on Cancer (IARC) classified glyphosate as a probable human carcinogen in 2015.

Glyphosate is best known as the main ingredient in Monsanto Co’s Roundup brand. More than 200m pounds are used annually by US farmers on their fields. The weedkiller is sprayed directly over some crops, including corn, soybeans, wheat and oats. Many farmers also use it on fields before the growing season, including spinach growers and almond producers.

Thompson’s detection of glyphosate was made as he was validating his analytical methods, meaning those residues will probably not be included in any official report.

Separately, FDA chemist Narong Chamkasem found “over-the-tolerance” levels of glyphosate in corn, detected at 6.5 parts per million, an FDA email states. The legal limit is 5.0 ppm. An illegal level would normally be reported to the Environmental Protection Agency (EPA), but an FDA supervisor wrote to an EPA official that the corn was not considered an “official sample”.

When asked about the emails and the agency’s testing, an FDA spokesman said only that the FDA had not found any illegal levels in corn, soy, milk or eggs, the four commodities it considers part of its glyphosate “special assignment”. He did not address the unofficial findings revealed in the emails.

The FDA’s official findings should be released later this year or early in 2019 as part of its 2016 annual residue report. The reports typically are released two to two and a half years after the data is collected.

Along with glyphosate, the agency has been trying to measure residues of the herbicides 2,4-D and dicamba because of projected increased use of these weedkillers on new genetically engineered crops. The FDA spokesman said that the agency has “expanded capacity” for testing foods for those herbicides this year.

Other findings detailed in the FDA documents show that in 2016 Chamkasem found glyphosate in numerous samples of honey. Chamkasem also found glyphosate in oatmeal products. The FDA temporarily suspended testing after those findings, and Chamkasem’s lab was “reassigned to other programs”, the FDA documents show. The FDA has said those tests were not part of its official glyphosate residue assignment.

Pesticide exposure through diet is considered a potential health risk. Regulators, Monsanto and agrochemical industry interests say pesticide residues in food are not harmful if they are under legal limits. But many scientists dispute that, saying prolonged dietary exposure to combinations of pesticides can be harmful.

Toxicologist Linda Birnbaum, who is director of the US National Institute of Environmental Health Sciences (NIEHS), said that current regulatory analysis of pesticide dangers does not account for low levels of dietary exposures.

“Even with low levels of pesticides, we’re exposed to so many and we don’t count the fact that we have cumulative exposures,” Birnbaum said.

The US Department of Agriculture was to start its own testing of foods for glyphosate residues in 2017 but dropped the plan.

The lack of government residue data comes as Monsanto attempts to bar evidence about glyphosate food residues from being introduced in court where the company is fighting off allegations its Roundup products cause cancer.

In a case set for trial on 18 June, San Francisco superior court judge Curtis Karnow recently denied the company’s motion to keep the jury from hearing about residues in food. The judge said that although Monsanto worries the information “will inflame the jury against Monsanto based on their own fear that they may have been exposed”, such information “should not be excluded”.
