Academics Review: The Making of a Monsanto Front Group

Print Email Share Tweet

Academics Review, a nonprofit 501(c)(3) organization launched in 2012, claims to be an independent group but documents obtained by U.S. Right to Know revealed it is a front group set up with the help of Monsanto and its public relations team to attack agrichemical industry critics while appearing to be independent.

Covert industry funding 

The Academics Review website describes its founders as “two independent professors,” Bruce Chassy, PhD, professor emeritus at the University of Illinois at Urbana-Champaign, and David Tribe, PhD, senior lecturer at the University of Melbourne, Australia. As of May 2018, the website claims, “Academics Review only accepts unrestricted donations from non-corporate sources to support our work.”

However, tax records show that the primary funder of Academics Review has been the Council for Biotechnology Information, a trade association that is funded and run by the largest agrichemical companies: BASF, Bayer, DowDuPont, Monsanto and Syngenta.

According to CBI tax records, the industry-funded group gave Academics Review a total of $650,000 in 2014 and 2015-2016. Tax records for AcademicsReview.org report expenses of $791,064 from 2013-2016 (see 2013, 2014, 2015, 2016). The money was spent on organizing conferences and promoting GMOs and pesticides, according to the tax records.

Emails reveal secret origin of academic front group

Emails obtained by U.S. Right to Know via state Freedom of Information requests revealed the inner workings of how Academics Review was set up as a front group with the help of Monsanto, its PR allies and industry funders. See “Monsanto Fingerprints Found All Over Attack on Organic Food,” by Stacy Malkan (6/30/2016).

Key facts and emails:

  • Eric Sachs, a senior public relations executive at Monsanto, said he would help find industry funding for Academics Review. “The key will be keeping Monsanto in the background so as not to harm the credibility of the information,” Sachs wrote to Chassy on November 30, 2010.
  • Academics Review was conceived as a front group that could attack critics of the agrichemical industry. According to a March 11, 2010 email chain, the group was established with the help of Monsanto executives along with Jay Byrne, former director of corporate communications at Monsanto who now runs a PR shop called v-Fluence Interactive; and Val Giddings, former VP of the biotech industry trade association BIO.
  • Byrne compared the concept as similar to – but better than – a front group set up by Rick Berman, a lobbyist known as  “Dr. Evil” and the “king of corporate front groups and propaganda” for his work to promote tobacco and oil industry interests under the cover of neutral-sounding groups. Berman’s “’Center for Consumer Freedom’ (ActivistCash.com) has cashed in on this to the extreme; and I think we have a much better concept,” Byrne wrote to Chassy on March 11, 2010.
  • Byrne said he was developing an “opportunities list with targets” for Monsanto comprised of “individuals organizations, content items and topic areas” critical of ag-biotech that “mean money for a range of well heeled corporations.”
  • Chassy indicated he was especially keen to go after the organic industry. “I would love to find a prime name in the middle of the organic aura from which to launch ballistic missiles,” he wrote on March 11, 2010. In 2014, Academics Review attacked the organic industry with a report it falsely claimed was the work of independent academics with no conflicts of interest.

Monsanto plan names Academics Review as “industry partner” 

Academics Review is an “industry partner”according to a confidential Monsanto PR document that describes the corporation’s plans to discredit the World Health Organization’s cancer research arm, the International Agency for Research on Cancer (IARC), in order to defend the reputation of Roundup weedkiller. On March 20, 2015, IARC announced it had classified glyphosate as Group 2A carcinogen, “probably carcinogenic to humans.”

The Monsanto PR document lists four tiers of industry partners to engage in its public relations efforts to discredit the cancer panel’s report. Academics Review was listed as a Tier 2 “industry partner” along with Genetic Literacy Project, Sense About Science, Biofortified, and the AgBioChatter academics list serve.

An Academics Review article dated March 25, 2015 claimed the “IARC glyphosate cancer review fails on multiple fronts.” The article linked to the industry-funded GMO Answers, the front group American Council on Science and Health and a Forbes article by Henry Miller that was ghostwritten by Monsanto.

Bruce Chassy’s ties to industry and its front groups

Professor Bruce Chassy, co-founder of Academics Review and president of the board, has been frequently cited in the media as an independent expert on GMOs, while he was also receiving undisclosed funds from Monsanto.

Chassy had received $57,000 in undisclosed funds over a two-year period from Monsanto to travel, write and speak about GMOs, according to WBEZ. The story reported that Monsanto also sent at least $5.1 million through the University of Illinois Foundation to university employees and programs between 2005 and 2015.

Chassy is on the “Board of Science and Policy Advisors” of the American Council on Science and Health, an industry funded front groupthat works with Monsanto. Chassy is also an “independent expert” for GMO Answers, a marketing website for GMOs and pesticides funded by the agrichemical industry.

David Tribe / Academics Review / Biofortified

David Tribe is co-founder of Academics Review, vice president of the Academics Review Board of Directors, and a reviewer on the 2014 Academics Review report attacking the organic industry. Tribe is also a member of the board of directors of Biology Fortified Inc., or Biofortified, another Monsanto “partner” group that assists with lobbying and public relations campaigns.

Industry-funded Biotech Literacy Project Boot Camps

The Biotech Literacy Project boot camps were industry-funded conferences organized by Academics Review and Genetic Literacy Project, another  Monsanto “partner” group. The boot camps trained scientists and journalists how to present GMOs and pesticides in a more positive light, and had explicit political aims to stave off GMO labeling and prop up flagging support for agrichemical industry products.

Boot camp organizers made false claims to journalists and scientists about the source of funds for the Biotech Literacy Project boot camps:

“I was offered a $2,000 honorarium, as well as expenses. I wrote back and asked who would provide the honorarium and was told it’d be a combination of funds from UC Davis, USDA, state money, and the Biotechnology Industry Organization (BIO).” (Journalist Brooke Borel, Popular Science)

“I need to be clear up front that our support comes from BIO, USDA, state-USAID and some foundation money so industry is indirectly a sponsor.We are 100% transparent about sponsorship.”  (Bruce Chassy email to scientists)

However, USDA and other government and academic sources named by the organizers denied funding the events and the only traceable source of funds appears to be the agrichemical industry-funded Council for Biotechnology Information, according to The Progressive.

Internal FDA Emails: Weedkiller Found in Granola and Crackers

Print Email Share Tweet

This article was published the Guardian on April 30, 2018

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…

Book Description

It’s the pesticide on our dinner plates, a chemical so pervasive it’s in the air we breathe, our water, our soil, and even found increasingly in our own bodies. Known as Monsanto’s Roundup by consumers, and as glyphosate by scientists, the world’s most popular weed killer is used everywhere from backyard gardens to golf courses to millions of acres of farmland. For decades it’s been touted as safe enough to drink, but a growing body of evidence indicates just the opposite, with research tying the chemical to cancers and a host of other health threats.

In Whitewash, veteran journalist Carey Gillam uncovers one of the most controversial stories in the history of food and agriculture, exposing new evidence of corporate influence. Gillam introduces readers to farm families devastated by cancers which they believe are caused by the chemical, and to scientists whose reputations have been smeared for publishing research that contradicted business interests. Readers learn about the arm-twisting of regulators who signed off on the chemical, echoing company assurances of safety even as they permitted higher residues of the pesticide in food and skipped compliance tests. And, in startling detail, Gillam reveals secret industry communications that pull back the curtain on corporate efforts to manipulate public perception.

Whitewash is more than an exposé about the hazards of one chemical or even the influence of one company. It’s a story of power, politics, and the deadly consequences of putting corporate interests ahead of public safety.

More Praise for Whitewash

“The book unravels a tapestry of pesticide industry tricks to manipulate the scientific truths about their products while placing profits above human health and the environment. As someone who has experienced similar actions by corporations firsthand in my work far too often, I am hopeful that Carey’s book will be a wake-up call for more transparency about the dangers surrounding many chemicals in the marketplace.” Erin Brockovich, environmental activist and author

Carey Gillam has brilliantly assembled the facts and describes how Monsanto and other agricultural chemical companies lied about their products, covered up the damaging data and corrupted government officials in order to sell their toxic products around the world.  David Schubert, Ph.D., Professor and Head of the Cellular Neurobiology Laboratory at the Salk Institute For Biological Studies

Carey Gillam is a brave warrior in the mold of Rachel Carson. She has exposed the ruthless greed and fraud which have led to the poisoning of our planet. Brian G.M. Durie, M.D. Chairman of the International Myeloma Foundation, oncology specialist and attending physician at Cedars-Sinai Medical Center

In the grand tradition of Silent Spring, Carey Gillam’s Whitewash is a powerful exposé that sheds light on a chemical that — to most of us — is both entirely invisible and yet profoundly damaging to our bodies and our environment. It is a deeply researched, entirely convincing exposé of the politics, economics and global health consequences implicit in the spread of the world’s most common herbicide. Gillam has done what all great journalists strive to do: she has made us see clearly what has long been right before our eyes. Highly recommended.  McKay Jenkins, author, Professor of English, Journalism and Environmental Humanities at the University of Delaware

USDA Drops Plan to Test for Monsanto Weed Killer in Food

Print Email Share Tweet

By Carey Gillam

The U.S. Department of Agriculture has quietly dropped a plan to start testing food for residues of glyphosate, the world’s most widely used weed killer and the key ingredient in Monsanto Co.’s branded Roundup herbicides.

The agency spent the last year coordinating with the Environmental Protection Agency (EPA) and the Food and Drug Administration (FDA) in preparation to start testing samples of corn syrup for glyphosate residues on April 1, according to internal agency documents obtained through Freedom of Information Act requests. Documents show that at least since January 2016 into January of this year, the glyphosate testing plan was moving forward. But when asked about the plan this week, a USDA spokesman said no glyphosate residue testing would be done at all by USDA this year.

The USDA’s plan called for the collection and testing of 315 samples of corn syrup from around the United States from April through August, according to the documents. Researchers were also supposed to test for the AMPA metabolite, the documents state. AMPA (aminomethylphosphonic acid) is created as glyphosate breaks down. Measuring residues that include those from AMPA is important because AMPA is not a benign byproduct but carries its own set of safety concerns, scientists believe.

On Jan. 11, USDA’s Diana Haynes wrote to colleagues within USDA: “Based on recent conversations with EPA, we will begin testing corn syrup for glyphosate and its AMPA metabolite April 1, 2017 with collection ending August 31, 2017. This program change will need to be announced at the February PDP Conference Call.” Haynes is director of a USDA Agricultural Marketing Service division that annually conducts the Pesticide Data Program (PDP), which tests thousands of foods for hundreds of different pesticide residues.

The USDA spokesman, who did not want to be named, acknowledged there had been a glyphosate test plan but said that had recently changed: “The final decision for this year’s program plan, as a more efficient use of resources, is to sample and test honey which covers over 100 different pesticides.” Glyphosate residue testing requires a different methodology and will not be part of that screening in honey, he said.

The USDA does not routinely test for glyphosate as it does for other pesticides used in food production. But that stance has made the USDA the subject of criticism as controversy over glyphosate safety has mounted in recent years. The discussions of testing this year come as U.S. and European regulators are wrestling with cancer concerns about the chemical, and as Monsanto, which has made billions of dollars from its glyphosate-based herbicides, is being sued by hundreds of people who claim exposures to Roundup caused them or their loved ones to suffer from non-Hodgkin lymphoma. Internal Monsanto documents obtained by plaintiffs’ attorneys in those cases indicate that Monsanto may have manipulated research regulators relied on to garner favorable safety assessments, and last week, Congressman Ted Lieu called for a probe by the Department of Justice into Monsanto’s actions.

Along with the USDA, the Food and Drug Administration also annually tests thousands of food samples for pesticide residues. Both agencies have done so for decades as a means to ensure that traces of weed killers, insecticides, fungicides and other chemicals used in farming do not persist at unsafe levels in food products commonly eaten by American families. If they find residues above the “maximum residue level” (MRL) allowed for that pesticide and that food, the agencies are supposed to inform the EPA, and actions can be taken against the supplier. The EPA is the regulator charged with establishing MRLs, also called “tolerances,” for different types of pesticides in foods, and the agency coordinates with USDA and FDA on the pesticide testing programs.

But despite the fact that glyphosate use has surged in the last 20 years alongside the marketing of glyphosate-tolerant crops, both USDA and FDA have declined to test for glyphosate residues aside from one time in 2011 when the USDA tested 300 soybean samples for glyphosate and AMPA residues. At that time the agency found 271 samples contained glyphosate, but said the levels were under the MRL – low enough not to be worrisome. The Government Accountability Office took both agencies to task in 2014 for the failure to test regularly for glyphosate.

Europe and Canada are well ahead of the United States when it comes to glyphosate testing in food. In fact, the Canadian Food Inspection Agency (CFIA) is preparing to release its own findings from recent glyphosate testing. The CFIA also routinely skipped glyphosate in annual pesticide residue screening for years. But it began collecting data in 2015, moving to address concerns about the chemical that were highlighted when the World Health Organization’s International Agency for Research on Cancer (IARC) classified glyphosate as a probable human carcinogen in March 2015.

Canadian food activist and researcher Tony Mitra obtained more than 7,000 records from CFIA about its glyphosate testing last year, and claims that results are alarming, showing glyphosate pervasive in many foods. CFIA would not respond to requests for comment about its glyphosate testing.

One of the USDA’s explanation’s for not testing for glyphosate over the years has been cost – the agency has said that it is too expensive and inefficient to look for glyphosate residues in food headed for American dinner tables. And because glyphosate is considered so safe, testing would be a waste of time, the USDA has stated. That argument mimics Monsanto’s own – the company, which patented glyphosate in 1974 and has been a dominant provider of glyphosate ever since, says if the USDA did seek to test for glyphosate residues in food it would be a “misuse of valuable resources.”

FDA TESTS REMAIN IN LIMBO

The FDA began its own limited testing program for glyphosate residues – what it called a “special assignment” – last year. But the effort was fraught with controversy and internal difficulties and the program was suspended last fall. Before the suspension, one agency chemist found alarming levels of glyphosate in many samples of U.S. honey, levels that were technically illegal because there have been no allowable levels established for honey by the EPA. That revelation caused angst in the beekeeping industry and at least one large honey company was sued by consumer organizations over the glyphosate contamination. The same chemist also found glyphosate levels in many samples of oatmeal, including infant oat cereal. The FDA did not publicize those findings, but they were revealed in internal records obtained through a FOIA request.

Officially, the FDA was only looking for glyphosate residues in corn, soy, eggs and milk in last year’s testing assignment, though internal records discussed tests on sugar beets, popcorn, wheat and other foods or grains. Newly obtained FDA documents show the agency is engaged now in a “glyphosate collaboration” designed to validate the testing methodology to be used by multiple FDA laboratories.

“Once the first phase of this collaboration is completed and approved by quality control reviewers, the special assignment can be restarted,” said FDA spokeswoman Megan McSeveney.

CropLife America, an industry organization that represents the interests of Monsanto and other agrichemical companies, keeps a close eye on the government’s pesticide residue testing. Last year the organization sought to diffuse potential legal problems related to glyphosate and other pesticides in honey by asking EPA to set a blanket tolerance that would cover inadvertent contamination of honey by pesticides. Records show regulators have found 26 different pesticides in honey samples in past tests.

CropLife also has complained to USDA that data from its testing program is used by proponents of organic agriculture to promote organics over conventional foods. The group last year sent USDA a series of questions about its testing, and asked USDA: “What can we do to assist you in fighting these scaremongering tactics?”

The USDA’s most recent published report on pesticide residues in food found that for 2015 testing, only 15 percent of the 10,187 samples tested were free from any detectable pesticide residues. That’s a marked difference from 2014, when the USDA found that over 41 percent of samples were “clean” or showed no detectable pesticide residues. But the agency said the important point was that most of the samples, over 99 percent, had residues below the EPA’s established tolerances and are at levels that “do not pose risk to consumers’ health and are safe.”

Many scientists take issue with using MRLs as a standard associated with safety, arguing they are based on pesticide industry data and rely on flawed analyses. Much more research is needed to understand the impact on human health of chronic dietary exposures to pesticides, many say.

New Data on Pesticides in Food Raises Safety Questions

Print Email Share Tweet

As American gather their families to share a Thanksgiving meal this week, new government data offers a potentially unappetizing assessment of the U.S. food supply: Residues of many types of insecticides, fungicides and weed killing chemicals have been found in roughly 85 percent of thousands of foods tested.

Data released last week by the U.S. Department of Agriculture shows varying levels of pesticide residues in everything from mushrooms to potatoes and grapes to green beans. One sample of strawberries contained residues of 20 pesticides, according to the “Pesticide Data Program” (PDP) report issued this month by the USDA’s Agricultural Marketing Service. The report is the 25th annual such compilation of residue data for the agency, and covered sampling the USDA did in 2015

Notably, the agency said only 15 percent of the 10,187 samples tested were free from any detectable pesticide residues. That’s a marked difference from 2014, when the USDA found that over 41 percent of samples were “clean” or showed no detectable pesticide residues. Prior years also showed roughly 40-50 percent of samples as free of detectable residues, according to USDA data. The USDA said it is not “statistically valid” to compare one year to others, however, because the mix of food sampled changes each year. Still the data shows that 2015 was similar to the years prior in that fresh and processed fruits and vegetables made up the bulk of the foods tested.

Though it might sound distasteful, the pesticide residues are nothing for people to worry about, according to the USDA. The agency said “residues found in agricultural products sampled are at levels that do not pose risk to consumers’ health and are safe…”

But some scientists say there is little to no data to back up that claim. Regulators do not have sufficient comprehensive research regarding how regular, repeated consumption of residues of multiple types of pesticides impact human health over the long term, and government assurances of safety are simply false, say some scientists.

“We don’t know if you eat an apple that has multiple residues every day what will be the consequences 20 years down the road,” said Chensheng Lu, associate professor of environmental exposure biology at the Harvard School of Public Health. “They want to assure everybody that this is safe but the science is quite inadequate. This is a big issue.”

The USDA said in its latest report that 441 of the samples it found were considered worrisome as “presumptive tolerance violations,” because the residues found either exceeded what is set as safe by the Environmental Protection Agency (EPA) or they were found in foods that are not expected to contain the pesticide residues at all and for which there is no legal tolerance level. Those samples contained residues of 496 different pesticides, the USDA said.

Spinach, strawberries, grapes, green beans, tomatoes, cucumbers and watermelon were among the foods found with illegal pesticide residue levels. Even residues of chemicals long banned in the United States were found, including residues of DDT or its metabolites found in spinach and potatoes. DDT was banned in 1972 because of health and environmental concerns about the insecticide.

Absent from the USDA data was any information on glyphosate residues, even though glyphosate has long been the most widely used herbicide in the world and is commonly sprayed directly on many crops, including corn, soy, wheat, and oats. It is the key ingredient in Monsanto Co.’s branded Roundup herbicide, and was declared a probable human carcinogen last year by a team of international cancer scientists working with the World Health Organization. But Monsanto has said glyphosate residues on food are safe. The company asked the EPA to raise tolerance levels for glyphosate on several foods in 2013 and the EPA did so.

The Food and Drug Administration also annually samples foods for residues of pesticides. New documents obtained from the FDA show illegal levels of two types of insecticides – propargite, used to kill mites, and flonicamid, usually aimed at killing aphids and whiteflies – were recently found in honey. Government documents also show that DEET, a common insect repellant, was recently detected by regulators in honey, and the herbicide acetochlor was found on mushrooms.

FDA scientists also reported illegally high levels of the neonicotinoid thiamethoxam found in rice, according to information from the agency. Syngenta has asked the Environmental Protection Agency to allow for higher residues of thiamethoxam permitted in numerous crops because the company wants it to have expanded use as a leaf spray. That request with EPA is still pending, according to an agency spokeswoman.

The most recent public residue report issued by the FDA shows that violation rates for pesticide residues have been climbing in recent years. Residue violations in domestic food samples totaled 2.8 percent for the year 2013; double the rate seen in 2009. Violations totaled 12.6 percent for imported foods in 2013, up from 4 percent in 2009.

Like the USDA, the FDA has skipped glyphosate in decades of testing for pesticide residues. But the agency did launch a “special assignment” this year to determine what levels of glyphosate might be showing up in a small group of foods. An FDA chemist reported finding glyphosate residues in honey and several oatmeal products, including baby food.

Private testing data released this month also reported the presence of glyphosate residues in Cheerios cereal, Oreo cookies and a variety of other popular packaged foods.

QUESTIONS ON CUMULATIVE IMPACTS

Whether or not consumers should worry about food containing pesticide residues is a matter of ongoing dispute. The trio of federal agencies involved in pesticide residue issues all point to what they refer to as “maximum residue limits” (MRLs), or “tolerances,” as benchmarks for safety. The EPA uses data supplied by the agrichemical industry to help determine where MRLs should be set for each pesticide and each crop the pesticides are expected to be used with.

As long as most of foods sampled show pesticide residues in food below the MRLs, there is no reason to worry, the USDA maintains. “The reporting of residues present at levels below the established tolerance serves to ensure and verify the safety of the Nation’s food supply,” the 2015 residue report states. The agrichemical industry offers even broader assurances, saying there is nothing to fear from consuming residues of the chemicals it sells farmers for use in food production, even if they exceed legal tolerances.

But many scientists say the tolerances are designed to protect the pesticide users more than consumers. Tolerances vary widely depending upon the pesticide and the crop. The tolerance for the insecticide chlorpyrifos on an apple, for instance, is very different than the amount of chlorpyrifos allowed on citrus fruits, or on a banana or in milk, according to government tolerance data.

In the case of chlorpyrifos, the EPA has actually said it wants to revoke all food tolerances because studies have linked the chemical to brain damage in children. Though the agency has long considered residues of chlorpyrifos safe, now the agency says, they may not be.

The “EPA cannot, at this time, determine that aggregate exposure to residues of chlorpyrifos, including all anticipated dietary exposures and all other non-occupational exposures for which there is reliable information, are safe,” the EPA said last year. Dow AgroSciences, which developed chlorpyrifos in the 1960s, is protesting the EPA efforts, arguing chlorpyrifos is a “critical tool” for farmers. In the latest USDA residue report, chlorpyrifos was found in peaches, apples, spinach, strawberries, nectarines and other foods, though not at levels considered to violate tolerances.

The EPA defends its work with tolerances, and says it has been complying with the Food Quality Protection Act that requires the EPA to consider the cumulative effects of residues of substances “that have a common mechanism of toxicity.” The agency says to set a tolerance for a pesticide, it looks at studies submitted by pesticide companies to identify possible harmful effects the chemical could have on humans, the amount of the chemical likely to remain in or on food and other possible exposures to the same chemical.

But critics say that is not good enough – assessments must consider more realistic scenarios that take into account the broader cumulative impacts of many different types of pesticide residues to determine how safe it is to consume the mixtures seen in a daily diet, they say. Given that several pesticides commonly used in food production have been linked to disease, declines in cognitive performance, developmental disorders, and attention-deficit/hyperactivity disorder in children, there is an urgent need for more in-depth analysis of these cumulative impacts, according to many scientists. They point to the National Research Council’s declaration years ago that “dietary intake represents the major source of pesticide exposure for infants and children, and the dietary exposure may account for the increased pesticide-related health risks in children compared with adults.”

“With the ubiquitous exposure to chemical mixtures, assurances of safety based on lists of individual toxicity thresholds can be quite misleading,” said Lorrin Pang, an endocrinologist with the Hawaii Department of Health and a former advisor to the World Health Organization.

Tracey Woodruff, a former EPA senior scientist and policy advisor who specializes in environmental pollutants and child health, said there is a clear need for more research. Woodruff directs the Program on Reproductive Health and the Environment at the University of California San Francisco School of Medicine.

“This is not a trivial matter,” she said. “The whole idea of looking at cumulative exposures is a hot topic with scientists. Evaluating individual tolerances as if they occur in solo is not an accurate reflection of what we know – people are exposed to multiple chemicals at the same time and the current approaches do not scientifically account for that.”

Critics say scrutiny of pesticide safety is likely to only soften given President-elect Donald Trump’s decision to name Myron Ebell to oversee transition efforts at the EPA. Ebell, director of the Center for Energy and Environment at the Competitive Enterprise Institute, is a staunch advocate of pesticides and their safety.

“Pesticide levels rarely, if ever, approach unsafe levels. Even when activists cry wolf because residues exceed federal limits that does not mean the products are not safe,” states the SAFEChemicalPolicy.org website Ebell’s group runs. “In fact, residues can be hundreds of times above regulatory limits and still be safe.”

The mixed messages make it hard for consumers to know what to believe about the safety of pesticide residues in food, said Therese Bonanni, a clinical dietitian at Jersey Shore University Medical Center.

“Although the cumulative effect of consuming these toxins over a lifetime is not yet known, short-term data suggests there is certainly a reason to be cautious,” she said. “The message to consumers becomes very confusing.”
