It is shameful that the EPA has chosen to rely on unpublished, industry-funded studies to determine that glyphosate is “Not Likely to be Carcinogenic to Humans,” when the World Health Organization’s panel of cancer experts has found that glyphosate is probably causing cancer. Moreover, unlike the WHO scientists, EPA scientists focused exclusively on studies that tested glyphosate as a single ingredient. Most products containing glyphosate have other ingredients that can make the pesticide more dangerous.

The evidence backing up WHO’s finding is strong: 

• Increased rates of non-Hodgkin lymphoma were found in occupational exposure studies of workers who handled glyphosate in the USA, Canada and Sweden. 

• Cancers of the kidney, blood vessels, stomach, and skin were observed in laboratory studies of rats and mice exposed to glyphosate. 

• Our bodies absorb glyphosate. This is indicated by the fact that glyphosate is found in the blood and urine of, not only agricultural workers but also, the urban people who are exposed only through the food they eat.  

• Our intestinal microbes metabolize glyphosate just like soil microbes do. When people are poisoned by glyphosate, aminomethylphosphoric acid (AMPA), a metabolite of glyphosate that’s found in contaminated soil and water, is found in their blood. 

• Glyphosate and Roundup induce DNA and chromosomal damage in mammals, and in human and animal cells in vitro. 

• Glyphosate, Roundup, and AMPA induce oxidative stress in rodents and in vitro. 

How can you ignore this independent science and turn a blind eye to the suffering of Americans who have or will get cancer because of exposure to Monsanto’s Roundup herbicide?

Please discard the unpublished industry-funded data and follow the WHO finding

Monsantos Roundup with glyphosate on a store shelf

Glyphosate, the main ingredient in Monsanto’s Roundup herbicide, is the most-used agricultural chemical ever. Mounting scientific evidence of its human health impacts indicates that it may also be the most devastating.

The U.S. Environmental Protection Agency (EPA) has been conducting its required 15-year re-registration review of glyphosate since 2009. The agency was supposed to reapprove or ban the chemical by the end of 2015. We assumed that glyphosate would get the stamp of approval for another 15 years while President Obama was still in office.  

Then, in March 2015, the World Health Organization’s (WHO) panel of cancer experts, the International Agency for Research on Cancer (IARC), did its own review of the latest science on glyphosate. The IARC panel of 17 scientists unanimously agreed to reclassify the chemical as a probable human carcinogen. 

The IARC cancer finding forced the EPA to take its glyphosate review more seriously. That slowed down the process. Now, the decision is in the hands of the Trump administration’s EPA.

Campaign to ban glyphosate alive and well, despite pro-chemical EPA

Under Trump, the EPA is controlled by the notorious Scott Pruitt who has a cozy relationship with Monsanto, one of his former campaign funders.

We probably have a better chance of getting Pruitt fired than we have of getting him to ban glyphosate.

That said, the campaign to ban Monsanto’s Roundup is winning around the globe. And here in the U.S., despite a pro-chemical EPA, there’s plenty of activity around opposition to glyphosate.

Non-Toxic Neighborhoods campaigners are getting localities to stop using glyphosate on parks and playgrounds. 

Testing that revealed glyphosate in Ben & Jerry’s ice cream and other so-called “natural” foods has spurred a movement to get these products out of grocery stores—which would mean getting glyphosate out of the U.S. food supply chain.

Even local hardware stores are dropping Roundup and going organic.

Cancer victims take Monsanto to court

Meanwhile, farmers, farm workers, landscapers and gardeners who used Roundup and developed non-Hodgkin lymphoma (NHL) are suing Monsanto in courts across the country. 

Earlier this year, in a federal court in California where 380 of these lawsuits have been combined into a single case, scientists educated the court on glyphosate-cancer science. The judge must review scientific experts’ methodologies for analyzing the scientific evidence to make sure they are valid. Ultimately jurors will decide whether the scientific evidence shows that Roundup causes NHL. The judge will determine which experts may testify at trial after a hearing set for May 10.  

According to Carey Gillam, reporting for U.S. Right to Know, and the plaintiffs’ attorneys, the following experts testified for the plaintiffs.

Beate Ritz, M.D., Ph.D., Chair of the Epidemiology Department at UCLA, walked the judge through a series of epidemiology studies conducted over the years that show statistically significant risk factors linking glyphosate to cancer. The literature shows that the risk to individuals considered “routine users” of glyphosate was significant, she testified. When asked if the studies she evaluated show that glyphosate has caused NHL in people, her reply: “Yes, I think they do.”
 
Dennis Weisenburger, M.D., Chair of the Pathology Department of the City of Hope Medical Center where he specializes in the study of non-Hodgkin’s lymphoma, described a series of studies that show DNA damage in people exposed to glyphosate, including through aerial spraying. Research shows that both glyphosate and formulations like Roundup cause genetic damage that leads to NHL, he said. In one study, the North American Pooled Project the risk for NHL increased almost twofold for people who used glyphosate more than two days per year. 

Alfred Neugut, M.D., Ph.D., a practicing medical oncologist and professor of cancer research, medicine and epidemiology at Columbia University, began his testimony by saying research shows a connection between glyphosate and NHL with great specificity. The consistency in study findings is something that cannot be ignored, he said, as scientists have seen repeated evidence linking glyphosate to NHL. “Every time you look what comes up? Glyphosate and NHL,” said Dr. Neugut. 

Charles Jameson, Ph.D., who served as program leader for the National Toxicology Program at NIH’s National Institute of Environmental Health Sciences for 12 years and was a member of the IARC working group that concluded glyphosate is a probable human carcinogen, detailed the body of research that led him to conclude that glyphosate and Roundup can cause NHL at real-world exposure levels that farmers, farm workers and others face when spraying the herbicide. The science showing that glyphosate-based herbicides cause oxidative stress is important, as is the known link to non-Hodgkin lymphoma, he explained

Christopher Portier, Ph.D., who over the course of a lengthy career, has held prominent leadership positions with the U.S. government, including, Associate Director of the National Institute of Environmental Health Sciences National Toxicology Program, Director of the National Center for Environmental Health, Center for Disease and Prevention, and Director of the Agency for Toxic Substances and Disease Registry, was also an “invited specialist” to the IARC review on glyphosate. “To a reasonable degree of scientific certainty, given the human, animal, and mechanistic evidence, glyphosate probably causes NHL, and the probability that glyphosate causes NHL is high,” he said.

Aaron Blair, Ph.D., the Overall Chair of the IARC glyphosate review, explained how he weighed the totality of the epidemiology studies to support his opinion that glyphosate is a probable human carcinogen.

Matthew Ross, Ph.D., part of the mechanism section of the IARC glyphosate review, explained why the strong evidence that glyphosate is genotoxic and causes oxidative stress are relevant to carcinogenicity in humans.

Chadi Nabhan, M.D., F.A.C.P, a board-certified clinical medical oncologist who, until last year, treated approximately 30 lymphoma patients per week, currently serves as Medical Director of Cardinal Health. In his testimony, Dr. Nabhan discussed the process by which IARC determines whether chemicals and substances are carcinogens. The agency has a high bar in consideration for what chemicals or substances it will review, he said. Exposures must be high and the animal data must be strong. Since 1965, IARC has reviewed over 1000 agents and found around 20 percent to be carcinogens. “In my opinion, the [NHL] risk [of exposure to glyphosate] is clinically significant enough that patients should be aware of it,” said Dr. Nabhan. “The IARC report is very convincing.”

Lawsuits reveal Monsanto-EPA collusion

If these experts are all permitted to testify without restriction, the court’s glyphosate-cancer review will be far more rigorous than the EPA’s. This is especially true given what we know now (from evidence uncovered in the lawsuit) about how the EPA’s review has been corrupted by Monsanto.

It all started when EPA scientists saw that a 1983 mouse study provided evidence that glyphosate was carcinogenic. Monsanto managed to convince EPA political appointees to overrule the scientists and declare that the study proved that glyphosate was not carcinogenic. This Orwellian misstatement of the facts continues to be repeated as a mantra by EPA decision-makers still under Monsanto’s sway.

The California lawsuit has also forced the EPA’s Office of Inspector General, an independent oversight body, to investigate whether a former deputy director in the EPA’s Office of Pesticide Programs, Jess Rowland, colluded with Monsanto to “kill” an investigation into the glyphosate-cancer connection.

The results of ongoing investigations and court testimony will likely undermine the legitimacy of the EPA’s decision, should it approve glyphosate. As consumers whose food supply is contaminated with glyphosate, we need to keep up the pressure on the EPA, regardless of Pruitt’s ties to Monsanto.
