I have observed in Europe, where Roundup use is prohibited, that Americans who claim intolerance to gluten are able to eat the bread without any side effects. I wonder if this is actually poisoning of Americans by the farmers using Round Up as opposed to Gluten intolerance? On a personal trip to Italy the mayor of a city in Piedmonte told me that cancer rates were through the roof 20 years ago and they assumed a direct link with Roundup. They banned the use and went back to traditional methods of weed control such as ploughing the weeds back into the soil. Not surprisingly there is a study being promoted in Italy to study the cancerous effect of round up..... Aivars.

In recent years, concerns over the health effects of glyphosate — the active ingredient in Roundup and other weed killer formulations — has risen exponentially. Researchers have discovered it not only may be carcinogenic,1 but may also affect your body’s ability to produce fully functioning proteins, inhibit the shikimate pathway (found in gut bacteria) and interfere with the function of cytochrome P450 enzymes(required for activation of vitamin D and the creation of nitric oxide and cholesterol sulfate).
Glyphosate also chelates important minerals, disrupts sulfate synthesis and transport, interferes with the synthesis of aromatic amino acids and methionine, resulting in folate and neurotransmitter shortages, disrupts your microbiome by acting as an antibiotic, impairs methylation pathways, and inhibits pituitary release of thyroid stimulating hormone, which can lead to hypothyroidism.2,3
Now, government researchers warn the Roundup formula is far more toxic than glyphosate alone. As reported by investigative journalist Carey Gillam:4
“The tests5 are part of the U.S. National Toxicology Program’s (NTP) first-ever examination of herbicide formulations made with the active ingredient glyphosate, but that also include other chemicals. While regulators have previously required extensive testing of glyphosate in isolation, government scientists have not fully examined the toxicity of the more complex products sold to consumers, farmers and others.”
Toxicology Testing Long Overdue
The NTP testing was done by request from the U.S. Environmental Protection Agency (EPA) following the International Agency for Research on Cancer (IARC) reclassification of glyphosate as a Class 2A probable carcinogen three years ago.6 At the time, the IARC noted concerns about glyphosate formulations possibly having increased toxicity due to synergistic interactions.
As it turns out, that’s exactly what the NTP testing found. According to the NTP’s summary of the results, glyphosate formulations “significantly altered” the viability of human cells by disrupting the functionality of cell membranes. Mike DeVito, acting chief of the NTP Laboratory, told Gillam, “We see the formulations are much more toxic. The formulations were killing the cells. The glyphosate really didn’t do it.”
While first-phase results do not indicate that weed killers like Roundup are carcinogenic, it does show that the formulations are more toxic than glyphosate in isolation (for which evidence of carcinogenic potential does exist), and that they have the ability to kill human cells.
Jennifer Sass, who works as a scientist with the Natural Resources Defense Council, added, “This testing is important, because the EPA has only been looking at the active ingredient. But it’s the formulations that people are exposed to on their lawns and gardens, where they play and in their food.”
Despite public assurances that Roundup is harmless, internal documents from Monsanto, obtained through previous Freedom of Information Act (FOIA) requests, reveal the company itself is unclear about the toxicity of Roundup as it has not been thoroughly studied. Internal discussions also reveal Monsanto employees have not been convinced the product is harmless. For example, in a 2002 email, Monsanto executive William Heydens said, “Glyphosate is OK but the formulated product … does the damage.”7
A 2003 company email8 from Monsanto toxicologist Donna Farmer, Ph.D., states, “You cannot say that Roundup is not a carcinogen … we have not done the necessary testing on the formulation to make that statement. The testing on the formulations are not anywhere near the level of the active ingredient.”
Farmer also adds that, “We cannot support the statement about ‘no adverse effects whatsoever on flora, or fauna or on the human body.’ Adverse effects are seen on flora (glyphosate is meant to kill vegetation), adverse effects on fauna — in studies with laboratory animals — even death is seen (LDS0 studies for example) …” Yet another company email sent in 2010 said,9 “With regards to the carcinogenicity of our formulations we don’t have such testing on them directly.”
Despite such internal discussions and doubts, in its “Benefits and Safety of Glyphosate” report published last year,10 Monsanto continues to claim that “Glyphosate-based herbicides are supported by one of the most extensive worldwide human health and environmental effects databases ever compiled for a pesticide product. Comprehensive toxicological and environmental fate studies conducted over the last 40 years have time and again demonstrated the strong safety profile of this widely used herbicide.”
Ramazzini Institute Seeking Donations for Global Safety Study
The highly respected Ramazzini Institute in Italy — which recently confirmed the link between cellphone radiation and Schwann cell tumors found by NTP researchers11,12,13 — is now raising funds14 to perform a comprehensive, global glyphosate study. Stage 1 would investigate the chemical’s carcinogenicity and chronic toxicity potential. The Institute explains its decision to look for public funding:
“Aiming to produce independent and solid scientific evidence, the Ramazzini Institute has decided not to accept any funding for the study from the industry that produces glyphosate-based herbicides or from the organic farming or food industry — to avoid all conflicts of interest.
Do you want to know if glyphosate is safe for you and your family? If you do, you can now help fund a study that you can trust. This is the most comprehensive independent study ever on the World’s most used herbicide, the study that you and your family deserve!”
