Geoffrey Kabat’s Ties to Tobacco and Chemical Industry Groups

Print Email Share Tweet

Geoffrey Kabat, PhD, is a cancer epidemiologist and author of two books arguing that that health hazards of pesticides, electromagnetic fields, secondhand tobacco smoke and other environmental exposures are “greatly overblown.” He is often quoted in the press as an independent expert on cancer risk. Reporters who use Dr. Kabat as a source should be aware of (and disclose) his longstanding ties to the tobacco industry and involvement with groups that partner with the chemical industry on PR and lobbying campaigns.

Front group leader and advisor

Dr. Kabat is a member of the board of directors of the Science Literacy Project, the parent group of Genetic Literacy Project, which works behind the scenes with Monsanto to promote and defend agrichemical products. Dr. Kabat is also a member of the board of scientific advisors of the American Council on Science and Health (ACSH), a group that receives funding from chemical, tobacco and pharmaceutical companies.

Both Genetic Literacy Project and ACSH partnered with Monsanto on a public relations campaign to attempt to discredit the International Agency for Research on Cancer (IARC) for its report that glyphosate, the main ingredient in Monsanto’s Roundup herbicide, is a probable human carcinogen. According to documents released via litigation:

  • A Monsanto PR plan (February 2015) named Genetic Literacy Project among the “industry partners” Monsanto planned to engage in its efforts to “neutralize [the] impact” of the IARC report. The goals of Monsanto’s plan were to “protect the reputation and FTO of Roundup” and “provide cover for regulatory agencies…” GLP has since posted more than 200 articles critical of the cancer agency.
  • Emails from February 2015 show that Monsanto funded ACSH on an ongoing basis and reached out to give ACSH the “full array” of Monsanto information about the IARC report on glyphosate. In the emails, Monsanto staffers discussed the usefulness of ACSH’s materials on pesticides, and one wrote, “You WILL NOT GET A BETTER VALUE FOR YOUR DOLLAR than ACSH.” (emphasis in original)
  • ACSH staffers told Monsanto the IARC glyphosate report was on their radar, and noted, “We are involved in a full-court press re: IARC, regarding ag-chemicals, DINP [phthalate] and diesel exhaust.”

These groups used similar messaging to attack the IARC cancer researchers as “scientific frauds” and “anti-chemical enviros” who “lied” and “conspired to misrepresent” the science on glyphosate. They cited Dr. Kabat as a key source for claims that IARC is “discredited” and “only enviro-fanatics” pay attention to reports on cancer hazard. Dr. Kabat has written that “there are literally no more studies we can do to show glyphosate is safe,” based on an interview with an anonymous expert.

Attacking scientists who raise cancer concerns

Another example of how Dr. Kabat aids the Monsanto-connected groups can be found in his efforts to discredit a different group of scientists who raised cancer concerns about glyphosate in a February 2019 meta-analysis. The meta-analysis, co-authored by three scientists who were tapped by EPA to serve on an expert scientific advisory committee on glyphosate, reported “compelling links” between exposures to glyphosate-based herbicides and increased risk of non-Hodgkin lymphoma.

Dr. Kabat skewered the analysis in an article that was first published on Forbes but was later removed after Forbes editors received complaints about Kabat’s lack of disclosure about his ties to ACSH. When questioned about the issue, Forbes said the article was pulled because it violated Forbes standards and Kabat would no longer be a contributor to Forbes.

Dr. Kabat’s deleted Forbes article can still be read on Science 2.0, a website run by the former director of ACSH, and a version appears on Genetic Literacy Project. GLP Executive Director Jon Entine promoted Dr. Kabat’s article along with suggestions that the scientists may have committed “deliberate fraud.”

Jon Entine is also tied in with the American Council on Science and Health. ACSH published Entine’s 2011 book that defends atrazine, a pesticide manufactured by Syngenta, which was funding ACSH.

Dr. Kabat’s longstanding tobacco ties

Dr. Kabat has published several papers favorable to the tobacco industry that were funded by the tobacco industry. He and his co-author on some of those papers, James Enstrom (a trustee of the American Council on Science and Health), have longstanding ties to the tobacco industry, according to a 2005 paper in BMJ Tobacco Control.

In a widely cited 2003 paper in BMJ, Kabat and Enstrom concluded that secondhand smoke does not increase the risk of lung cancer and heart disease. The study was sponsored in part by the Center for Indoor Air Research (CIAR), a tobacco industry group. Although that funding was disclosed, a follow-up analysis in BMJ Tobacco Control found that the disclosures provided by Kabat and Enstrom, although they met the journal’s standards, “did not provide the reader with a full picture of the tobacco industry’s involvement with the study authors. The tobacco industry documents reveal that the authors had long standing financial and other working relationships with the tobacco industry.” (emphasis added)

This table in the BMJ Tobacco Control paper reports the early ties:

In 2019, a search for Geoffrey Kabat in the UCSF Tobacco Industry Documents brings up over 800 documents, including a 2007 invoice to Phillip Morris for over $20,000 for “consulting on the health effects of low-yield cigarettes” billed at $350 an hour.

In 2008, Kabat and Enstrom published a paper partly funded by Phillip Morris reporting that previous assessments appeared to have overestimated the strength of the association between environmental tobacco smoke and coronary heart disease.

In 2012, Dr. Kabat co-authored a paper finding that mentholated cigarettes were not an important contributor to esophageal cancer. For that paper, Dr. Kabat declared he had “served as a consultant to a law firm and to a consulting firm on the health effects of menthol cigarettes.”

Drew Kershen: Agrichemical Industry Front Group Ringleader

Print Email Share Tweet

Drew Kershen, professor emeritus at the University of Oklahoma College of Law, is a close ally of the agrichemical industry. He argues for deregulation of genetically engineered plants and animals and against transparency. Kershen has played a key role in agrichemical industry-funded promotional efforts and front groups that lobby for industry interests. Kershen does not disclose funding sources.

Agrichemical industry ties and front group leadership

Genetic Literacy Project / Science Literacy Project

Kershen is a board member of Genetic Literacy Project, a front group that partners with Monsanto to do public relations for genetically engineered foods and pesticides, and does not accurately disclose its funding. Documents reveal that the Genetic Literacy Project:

Kershen is also a board member of the Science Literacy Project, the 501(c)(3) parent organization of the Genetic Literacy Project. Both are directed by Jon Entine, a longtime PR ally of the chemical industry.

According to 2015 tax records, Jon Entine and the Science Literacy Project assumed control of the Statistical Assessment Service (STATS), a group formerly affiliated with the Center for Media and Public Affairs (CMPA) and the Genetic Literacy Project. Operations for STATS were folded into Sense About Science USA, which shares the same address of record with Science Literacy Project.

The founders of STATS, CMPA and Sense About Science did public relations work for the tobacco industry and these groups are not independent arbiters of science, according to a 2016 investigation in The Intercept.

For more information, see USRTK fact sheets on Jon Entine and Genetic Literacy Project and Sense About Science/STATS.

Secretary of Academics Review Front Group

Kershen was the secretary of the board of directors of Academics Review, according to its 2016 tax records. Academics Review claimed to be an independent group, but documents obtained by U.S. Right to Know revealed it was a front group set up with the help of Monsanto to attack critics of the agrichemical industry while appearing to be independent.

Kershen was a reviewer for a 2014 report by Academics Review that tried to discredit the organic industry; the press release for the report claimed that it was work of independent academics with no conflicts of interest.

Tax records show that the primary funder of Academics Review was the Council for Biotechnology Information, a nonprofit organization funded and run by BASF, Bayer, DowDuPont, Monsanto and Syngenta. CBI gave a total of $600,000 to Academics Review in 2014 and 2015-2016.

Why Forbes Deleted Some Drew Kershen Articles

Kershen co-authored several articles that were deleted by Forbes and Project Syndicate after his co-author, Henry Miller, was caught using a column ghostwritten by Monsanto as his own work in Forbes. The New York Times revealed the ghostwriting scandal in 2017.

Kershen and Miller also co-wrote articles for Slate, National Review, the Hoover Institution and the American Council on Science and Health (an industry-funded front group) arguing against labeling and regulating genetically engineered foods, attacking industry critics, and claiming “the world’s poor are suffering and dying unnecessarily” due to the “gratuitous regulation demanded by activists.”

GMO Answers

Kershen is an “ambassador expert” for GMO Answers, a marketing and PR website for genetically engineered foods that is funded by the big agrichemical companies via the Council for Biotechnology Information, and run by the public relations firm Ketchum.

Intervened in Transparency Lawsuit to Suppress Public Disclosure

Several documents reported in this fact sheet, which exposed undisclosed ties between corporations and front groups, were first obtained via Freedom of Information requests by U.S. Right to Know. Kershen has intervened in lawsuits to try to stop further disclosure, as the Freedom of the Press Foundation reported in February 2018.

Why Forbes Deleted Some Kavin Senapathy Articles

Print Email Share Tweet

Who pays Kavin Senapathy to promote GMOs? 

Kavin Senapathy emerged as a writer in 2015 with articles promoting GMOs, defending pesticides and attacking critics of the agrichemical industry, many of them published in Forbes. She does not disclose her funding sources.

In 2017, Forbes deleted seven articles Senapathy co-authored with Henry I. Miller, a former Hoover Institution fellow, following revelations in the New York Times that Monsanto ghostwrote an article published under Miller’s name in Forbes. Forbes also removed an article Senapathy wrote about transparency, which lacked transparency. Still up on the Forbes site is an article she co-wrote with Cameron English, who works for the American Council on Science and Health, a front group paid by Monsanto.

Senapathy’s Linked In profile lists her as a contributing writer to Genetic Literacy Project, another agrichemical industry front group that works closely with Monsanto.

Senapathy co-founded March Against Modification Myths (MAMyths), a group that organizes protests against biotechnology critics (and an affiliate of the GMO promotion group Biofortified). She co-authored a 2015 book that promotes GMOs, claims aspartame and MSG are safe, and purports to explain the “facts behind those toxic pesticide scares.”

At Least Seven Articles Removed by Forbes 

Collaboration with Henry I. Miller 

Senapathy began sharing a byline with Henry Miller in 2015 on a series of articles in Forbes defending GMOs. The articles are promoted here by the Hoover Institution, a policy think tank that receives funding from right wing foundations and corporations.

Forbes deleted the Miller/Senapathy articles in the wake an August 2017 New York Times report:

“Documents show that Henry I. Miller … asked Monsanto to draft an article for him that largely mirrored one that appeared under his name on Forbes’s website in 2015 … Forbes removed the story from its website on Wednesday and said that it ended its relationship with Mr. Miller amid the revelations.”

An article in Retraction Watch quotes Mia Carbonell, senior VP of global communications at Forbes:

“All contributors to Forbes.com sign a contract requiring them to disclose any potential conflicts of interest and only publish content that is their own original writing.  When it came to our attention that Mr. Miller violated these terms, we removed all of his posts from Forbes.com and ended our relationship with him.”

The emails between Miller and a Monsanto executive show how corporations work with writers such as Miller to promote industry talking points while keeping their collaborations secret. In this case, a Monsanto executive asked Miller to write a column defending glyphosate and provided him with a “still quite rough draft” as “a good start for your magic.” The draft appeared a few days later in Forbes, largely unchanged, under Miller’s name.

Transparency Blunder

Forbes also removed at least one article with Senapathy’s solo byline. The August 17 piece, “This Crowdfunded Experiment Offers a Lesson on Transparency” (which now appears on Medium), criticized Monsanto for ghostwriting safety reviews for glyphosate, describing the incident as a “transparency blunder” and a “PR gaffe.” Although published weeks after news reports that Monsanto ghostwrote an article for her collaborator Henry Miller, Senapathy’s article about transparency neglected to mention that fact.

“Legitimate objections” raised about “independence”

In a Sept. 2015 Project Syndicate article titled “GMOs and Junk Science,” Senapathy and Miller accused the organic and natural food industries of abusing scientific authority and producing propaganda. Project Syndicate added this editor’s note to the piece on August 4, 2017:



“Legitimate objections have been raised about the independence and integrity of the commentaries that Henry Miller has written for Project Syndicate and other outlets, in particular that Monsanto, rather than Miller, drafted some of them. Readers should be aware of this potential conflict of interest, which, had it been known at the time Miller’s commentaries were accepted, would have constituted grounds for rejecting them.”

Underhanded Tactics of MAMyths 

Senapathy is co-founder of March Against Myths of Modification, a group that organizes protests to confront critics of the agrichemical industry, such as Dr. Vandana Shiva, and sometimes uses underhanded tactics. In 2016, MAMyths orchestrated a failed attempt to derail a Center for Food Safety event in Hawaii featuring Vani Hari, The Food Babe.

As Hari explained in an article about the episode:

“24 hours before I was scheduled to take the stage, I was informed by Hawaii CFS that the pro-GMO and satire activist group (MAMyths) launched a campaign to sabotage the event. The tickets to the event were free, but there were a limited quantity available as the venue could only accommodate a certain number of people …

MAMyths asked their followers to reserve blocks of tickets using fake names and fake emails so that it would appear to be “sold out” and that we would be speaking to an empty venue. They reserved over 1,500 tickets using names like “Fraud Babe,” “Organic is Dumb,” “Susi Creamcheese,” and “Harriett Tubman” from traced IP addresses outside of Hawaii and overseas in the United Kingdom, Australia, China, Thailand, Germany, Sweden, and the Netherlands.

They were unsuccessful because Hawaii CFS discovered where these bogus requests were coming from and were able to easily cancel their reservations.”

MAMyths claims on their website they are “not paid by Monsanto or any other industry. We are all volunteers with a passion for justice and do this of our own free will.” According to Senapathy’s bio on the site, “She believes that critical thinking is key in raising well-rounded children, and that embracing biotechnology is imperative to this objective.”

Book Describes the Food Movement as a “Terrorist Faction”

Senapathy is co-author of a book, “The Fear Babe: Shattering Vani Hari’s Glass House,” published in October 2015 by Senapath Press. The book promotes genetically engineered foods, claims aspartame and MSG are safe, and purports to explain the “facts behind those toxic pesticide scares.”

Co-authors are Mark Alsip, a blogger for Bad Science Debunked, and Marc Draco, who is described as a veteran member of the Banned by Food Babe Facebook page. The forward was written by University of Florida Professor Kevin Folta.

The book’s forward describes the food movement as “a modern day elite and well financed terrorist faction sworn to use fear to force political change around food,” and an “agile and sneaky terrorist group. Like all terrorist groups they achieve their objectives through the implementation of fear and coercion.”
