Monsanto’s Roundup Herbicide Found To Be 125X More Toxic Than Regulators Claim

90% of the food in the supermarket is grown using Roundup... Organic food is now allowed to contain a percentage of GMO.Soon the corporations will push the FDA into allowing Roundup on organic food.

Monsanto’s Roundup Herbicide Found To Be 125X More Toxic Than Regulators Claim


Roundup herbicide was manufactured by Monsanto and is one of the worlds most widely used herbicides around the world. Within the past few years, numerous studies have emerged linking its main ingredient, glyphosate, to a number of health ailments that include cancer, Parkinson’s disease, Alzheimer’s disease and more. Sri Lanka recently joined the long list ( and growing) of countries who have completely banned it, citing a link to deadly kidney disease. You can read more about that and view other studies here. Russia also became the latest country to completely ban GMOs, you can read more about that here

A new study published in the journal Biomedical Research International  shows that Roundup herbicide is 125 times more toxic than its active ingredient glyphosate studied in isolation.(1)  The eye opening abstract reads as follows:
“Pesticides are used throughout the world as mixtures called formulations. They contain adjuvants, which are often kept confidential and are called inerts by the manufacturing companies, plus a declared active principle, which is usually tested alone. We tested the toxicity of 9 pesticides, comparing active principles and their formulations, on three human cell lines. Glyphosate, isoproturon, fluroxypyr, pirimicarb, imidacloprid, acetamiprid, tebuconazole, epoxiconazole, and prochloraz constitute, respectively, the active principles of 3 major herbicides, 3 insecticides, and 3 fungicides.  Despite its relatively benign reputation, Roundup was among the most toxic herbicides and insecticides tested. Most importantly, 8 formulations out of 9 were up to one thousand times more toxic than their active principles. Our results challenge the relevance of the acceptable daily intake for pesticides because this norm is calculated from the toxicity of the active principle alone. Chronic tests on pesticides may not reflect relevant environmental exposures if only one ingredient of these mixtures is tested alone.” (1)

Greenmedinfo describes it perfectly, stating that this just further illustrates the “deceptive semantics of pesticide formulations and their regulation.” This paper does indeed prove that the agrochemical industry conceals the truth about how toxic their chemicals really are, is this not a crime? Is this not mass poisoning through deception? Who exactly is setting the ‘acceptable’ amount when it’s clear there should be no acceptable amount at all?

It’s also worth mentioning here that the African Center for Bio-safety orders Monsanto to stop making false claims about GMOs, you can find out more about that here.

“The problem of underestimated toxicological risk is so severe that the researchers describe previous research which found unexpected toxicity in so-called ‘inert’ adjuvants that were up to 10,000 times more toxic than the so-called active principle glyphosate itself, revealing them to be a greater source for secondary side effects than the main ingredient itself. They also note that this ‘synergistic toxicity’ may explain the results of previous long-term animal research where glyphosate-based formulations showed toxicity in the parts per trillion range that could not be explained by glyphosate alone” (2)(3)

If you think about it, it seems insidious that Roundup herbicide is still heavily used in North America despite the numerous studies that have surfaced illustrating its extreme toxicity. It’s time for North America to do what what many other countries have already done, completely ban these pesticides and the GMOs that go with them.

Study: Roundup diluted by 99.8 percent still destroys human DNA

 A new study published in the journal Archives of Toxicology proves once again that there really is no safe level of exposure to Monsanto's Roundup (glyphosate) herbicide formula for genetically-modified organisms (GMOs). According to the new findings, Roundup, which is applied by the tens of thousands of tons a year all around the world, is still toxic to human DNA even when diluted to a mere 0.02 percent of the dilution amount at which it is currently applied to GM food crops.

Numerous studies have already identified the fact that Roundup causes DNA damage, not to mention endocrine disruption and cancer. But this new study, which originates out of the Medical University of Vienna, is one of the first to illustrate Roundup's toxicity at such drastically diluted levels, which is a direct contradiction of the agri-giant's talking points about the supposed safety of Roundup.

"Comparisons with results of earlier studies with lymphocytes and cells from internal organs indicate that epithelial cells are more susceptible to the cytotoxic effects and DNA-damaging properties of the herbicide and its formulation," wrote the authors in their abstract.

"Since we found genotoxic (DNA damaging) effects after short exposure to concentrations that correspond to a 450-fold dilution of spraying used in agriculture, our findings indicate that inhalation may cause DNA damage in exposed individuals."

Interestingly, it is not so much just the glyphosate ingredient in Roundup that is extremely poisonous, as much as it is this chemical's amplified toxicity in the presence of other additives in the formula. Polyoxyethyleneamine, for instance, a surfactant that facilitates glyphosate's absorption into cells, has been found to significantly increase Roundup's synergistic toxicity in humans.

Despite Monsanto's claims to the contrary, Roundup is clearly an exceptionally toxic chemical that has no legitimate place in agriculture. According to data compiled by GreenMedInfo.com, Roundup is linked to causing Non-Hodgkin Lymphoma, imbalanced hormones in children, DNA damage, low testosterone, endocrine disruption, liver cancer, meningitis, infertility, skin cancer, kidney damage, and even uranium poisoning (http://www.greenmedinfo.com/toxic-ingredient/glyphosate).

Environmentally, Roundup is a pervasive threat to air, water, and particularly groundwater and drinking supplies, as studies have shown that it does not effectively biodegrade after being sprayed. Back in the fall, the U.S. Geological Survey (USGS) released data showing that air and water all across America's "bread belt," where much of our nation's food is grown, is highly contaminated with glyphosate

USDA Scientist Reveals All

Glyphosate Hazards to Crops, Soils, Animals, and Consumers

In less than an hour, Don Huber, professor emeritus at Purdue University and USDA senior scientist (see Box) delivered to the UK Houses of Parliament a damning indictment of glyphosate agriculture as a most serious threat to the environment, livestock, and human health [1].
Don Huber

Don Huber, Emeritus Professor at Purdue University and senior scientist on USDA’s National Plant Disease Recovery System, has been a plant physiologist and pathologist for over 40 years. His academic career began with 8 years as a cereal pathologist at the University of Idaho, and the next 35 years at Purdue University where he specialised in soil-borne disease control, physiology of disease, and microbial ecology. For the past 20 years, he has conducted extensive research into the effects of glyphosate on crops, in response to the increase in crop diseases on glyphosate-applied fields.

Since his letter to the US Secretary of State Tom Vilsak was leaked in February 2011, there has been a great deal of controversy over what Huber described as a pathogen “new to science” and abundant in glyphosate-tolerant GM crops (see [2] Emergency! Pathogen New to Science Found in Roundup Ready GM Crops?, SiS 50). As he concluded in the letter: “We are now seeing an unprecedented trend of increasing plant and animal diseases and disorders. This pathogen may be instrumental to understanding and solving this problem”.

His talk linked glyphosate to reduced nutrient availability in plants, increasing plant diseases, the emergence of a new pathogen, animal illness and possible effects on human health (see [3, 4] Glyphosate Tolerant Crops Bring Death and Disease, Scientists Reveal Glyphosate Poisons Crops and Soil, SiS 47).
Pathogen new to science

The conversion of US agriculture to monochemical herbicide practice has resulted in the extensive use of glyphosate herbicides. Coincidentally, farmers have been witnessing deterioration in the health of corn, soybean, wheat and other crops, and epidemics of diseases in small grain crops. All are associated with the extensive use of glyphosate, which has increased further since the introduction of glyphosate-tolerant, Roundup Ready (RR) crops.

Glyphosate immobilises nutrients required to maintain plant health and resistance to disease. This weakening of the plants defence could explain the infestation of GM crops with the new pathogen, which has now been observed in horse, sheep, pigs, cows, chicken, multiple animal tissues including reproductive parts (semen, amniotic fluid), manure, soil, eggs, milk, as well as the common fungal pathogen that is currently infesting RR crops, Fusarium solani fsp glycines mycelium. All are coming into contact with glyphosate either through direct exposure or consumption through animal feed. It is also highly abundant in crops suffering from plant Goss’ wilt and sudden death syndrome.

The pathogen can be cultured in the lab, and has been isolated from livestock foetal tissue, replicated in the lab and re-introduced back into the animals. It appears to be very common and may well be interacting with the effects of glyphosate on both plants and animals, exacerbating disease and causing reproductive failure in livestock (see below). Although great expectations have been placed on Huber to publish his findings, he insists that before this can be done, further resources are necessary to be able to characterise the ‘entity’ and identify what type of species it is, including sequencing of its genome. This is a slow process and once complete, it is his intention to publish the work in a peer-reviewed journal.
Understanding glyphosate’s mode of action

Recognising glyphosate’s mechanism of action is the key to understanding how it may exert detrimental effects on the health of crops, animals, and the environment alike. Glyphosate is a broad-spectrum herbicide that interacts with a range of physiological processes in the plant and its environment. Although it is most commonly recognised to work through inhibition of the plant enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) involved in the production of aromatic amino acids in the shikimate pathway, it was actually first patented as a strong metal-chelator that binds to metals including manganese, magnesium, iron, nickel, zinc and calcium, many of which are important micronutrients acting as co-factors for plant enzymes in different physiological processes including the plants’ defence system. Indeed, it is actually through chelation of manganese that the EPSPS enzyme is inhibited.

Rendering plants more susceptible to disease through glyphosate’s pathogenic activity is actually the way it exerts its herbicidal activity. This is done not just through immobilising nutrients in the plant but also impacting the agricultural system as a whole. Consistently, if glyphosate does not reach the root of a plant or the plant is grown in a sterile soil, the plant is not killed.

Once in the soil, glyphosate is later immobilised through the chelation of cations, and is therefore very stable and not easily degraded. However, phosphorus (including phosphorus fertilisers) can desorb the herbicide, making it active once again in the soil.
