A new review of the scientific literature shows that glyphosate herbicides may be toxic below regulatory safety limits. Dr Robin Mesnage and co-authors examined a number of different types of toxic effects to arrive at their conclusions, including liver and kidney toxicity, neurotoxicity, carcinogenicity, reproductive toxicity, and teratogenicity (ability to cause birth defects). Unlike regulatory authorities, the researchers considered studies from the independent literature, as well as the few industry toxicity studies, conducted in support of regulatory approvals, that have been made public. They shared this approach of considering the entirety of the published literature with the World Health Organization’s cancer agency IARC, which recently concluded that glyphosate is a probable carcinogen. The new review shows that endocrine (hormone) disruptive effects can occur below the doses deemed not to cause any toxic effects in industry studies performed for regulatory approvals. Endocrine disruption may increase the risk of certain types of cancer. Yet regulatory studies do not test low dose exposures for endocrine disruptive effects.
Prof Christopher Portier, one of the co-authors of the recent report by the World Health Organisation’s International Agency for Research on Cancer (IARC), which determined that glyphosate is a probable carcinogen, said at a scientific briefing today, “Glyphosate is definitely genotoxic. There is no doubt in my mind.” “Genotoxic” means it damages DNA. It is widely believed by regulators that for genotoxic chemicals that are also carcinogenic, as glyphosate appears to be, there is no safe level of exposure.
The decision by an organization of the world’s leading cancer experts to classify the herbicide 2,4-D as a possible carcinogen underscores the risk posed by the U.S. government’s recent approval of 2,4-D for use on genetically engineered, or GMO, crops. 2,4-D is one of the two active ingredients in Enlist Duo, a toxic weed-killing cocktail marketed by Dow AgroSciences, which the U.S. Environmental Protection Agency recently approved for use in 15 states. The other herbicide in Enlist Duo is glyphosate, which the international cancer agency had previously classified as “probably carcinogenic.” Exposure to both chemicals has separately been linked to non-Hodgkin lymphoma.
The Green party made their warning after testing the breast milk of 16 women from a variety of German regions. Traces of glyphosate, a chemical used in weed-killers, amounting to between 0.210 and 0.432 nanograms per mililitre were recorded. In drinking water a quantity of no more than 0.100 nanograms of the substance is allowed. Irene Witte, professor of toxicology at the University of Oldenburg described the findings as “intolerable.” “I would never have guessed that the quantities are so high,” she said.
Dr. Anthony Samsel was interviewed in 2015 by Tony Mitra, where he discussed certain documents he has in his possession from the Environmental Protection Agency (EPA) that allegedly show Monsanto knew about research connecting glyphosate to cancer since the 1970s. In this follow-up interview, Dr. Samsel discusses how the rat chow used in the laboratory feeds he analyzed were all contaminated with glyphosate. This is significant, as it means standard rat chow used in scientific studies have probably been contaminated since they started using GMO feeds that had been sprayed with glyphosate.
French Ecology Minister Segolene Royal announced today a ban on the sale of popular weedkiller Roundup from garden centres, which the UN has warned may be carcinogenic. The active ingredient in Roundup, glyphosate, was in March classified as "probably carcinogenic to humans" by the UN's International Agency for Research on Cancer (IARC). The weedkiller, used by amateur gardeners as well as farmers, is the star product of American biotechnology giant Monsanto. "France must be on the offensive with regards to the banning of pesticides," Royal said on French television. "I have asked garden centres to stop putting Monsanto's Roundup on sale" in self-service aisles, she added.
Swiss supermarket giants Coop and Migros have announced that they will no longer sell products that contain glyphosate, following the World Health Organization’s report stating that glyphosate is a probable human carcinogen. They have also announced that they will be exploring non-toxic alternative weed-killers. Coop’s and Migros’s decisions followed German giant retailer REWE Group’s decision, announced in early May, to remove glyphosate herbicides from the shelves of their 350 ‘toom Baumarkt DIY’ starting in September.
Glyphosate Causes Cancer: EPA “Trade Secret” Sealed Files Reveal Cancer Link Known Back in the 1970s
In 2015, Dr. Anthony Samsel was interviewed by Tony Mitra, where he discussed certain documents he has in his possession from the Environmental Protection Agency (EPA) that allegedly show Monsanto knew about research connecting glyphosate to cancer since the 1970s. Dr. Samsel states that the documents he received from the EPA are "trade secret" documents belonging to Monsanto. These documents allegedly are safety studies about glyphosate from the late 1970s to the early 1980s, and others beyond those dates. Monsanto allegedly asked the EPA to seal these documents as "trade secrets" so no one else could review the data from these studies. Dr. Samsel stated that he is still sifting through all the data from these sealed documents, and that he is about to write a paper on glyphosate and cancer. He states that these "trade secret" documents are documents that Monsanto had the EPA seal so that nobody could revisit the data. According to Samsel, these documents show: "unequivocally, that glyphosate causes cancer. Should it be on the market? No. Should it be in our food? No." He states that taking glyphosate off the market will not necessarily solve the problem if they substitute it with another herbicide. "No herbicide belongs in our food. Whether it is 2,4-D, Dicamba, Glufosinate.... there should be no herbicides in our food because it disrupts our bacterial homeostasis, and it disrupts our immune system. When we disrupt our bacteria and the microbiota within us, disease ensues. Disease begins with the destruction of our microbiome."
Sri Lankan President Maithripala Sirisena today announced that the imports and release of the agrochemical Glyphosate will be banned with immediate effect. The President, who was the Health Minister of the former government, said the government has decided to totally ban the imports of Glyphosate, which is linked to the kidney disease, as the number of kidney patients was surging.
Will Foods Contaminated with Glyphosate have to Carry a Prop 65 Cancer Warning to be Sold in California?
In late March, the International Agency for Research on Cancer (IARC), a division of the World Health Organization (WHO), determined that glyphosate—the active ingredient in Monsanto’s herbicide Roundup—is a Class 2 A “probable carcinogen.” This determination is nothing short of devastating to Monsanto and other chemical technology companies that rule our food supply, and recent “astroturf” attack on Dr. Oz reveals just how desperate they are to quell rising concerns. Not only is the IARC considered the global gold standard for carcinogenicity studies, it’s also one of the research agencies from which the California agency of environmental hazards gets its data to declare carcinogens under Prop 65. So, eventually, foods containing glyphosate will likely have to carry a Prop 65 cancer warning label to be sold in California.
