(NaturalNews) For years, Monsanto's bestselling glyphosate-containing weedkiller, Roundup, has been used to spray gardens, parks, playgrounds and GM crops on farms. Over the years, they propagated the belief that glyphosate is safe to use and does not accumulate in the human body."If ingested, glyphosate is excreted rapidly, does not accumulate in body fat or tissues, and does not undergo metabolism in humans. Rather, it is excreted unchanged in the urine," stated senior Monsanto scientist Dan Goldstein.Many studies, however, have shown that glyphosate may not be as innocent as some of us may think. It has been linked to an increased risk of cancer, gut and hormone imbalances, autism, Alzheimer's disease, depression, anxiety, Parkinson's disease and prion diseases. These potential health risks have been crushed by the billion-dollar industry.Thanks to new findings and an episode of, that went viral, the toxicity of our most popular herbicide has raised new questions and concerns for public health. This resulted in an attack letter from the medicine and biotech corporations through the American Council on Science and Health front group, which is led by a doctor convicted for fraud against the U.S. government.Read more about the American Council on Science and Health here: TruthWiki.org The International Agency for Research on Cancer (IARC) -- the cancer evaluation unit of the World Health Organization -- set up an eight-day meeting with 17 scientific experts earlier this year to assess whether certain pesticides can cause cancer in humans. The IARC declared glyphosate to be "probably carcinogenic," but experts note that it probably should be listed in the "carcinogenic" category.Recently, a pilot study from Moms Across America andanalyzed the samples of breast milk , urine and drinking water. Levels found in breast milk were up to 1,600 times higher than the maximum detectable limit allowed in drinking water in Europe. In the U.S., however, maximum allowance is set much higher by the Environmental Protection Agency (EPA), because of the assumption that glyphosate is not bio-accumulative.Dr. Angelika Hilbeck, senior scientist at the Institute of Integrative Biology in Zurich, stated, "If confirmed in a full investigation, it seems that glyphosate has become a ubiquitous chemical in terms of presence and persistence. This data also offers a first indication of potential accumulation in the human body, giving newborns a substantial dose of synthetic chemicals as a 'gift' for their start into life, with unknown consequences. This is reckless and irresponsible conduct in a democratic society, which still has a living memory of previous reckless chemical contaminations, such as DDT. It seems we either did not learn, or we have forgotten, our lessons from Rachel Carson!"Jessica M. from Virginia, one of the mothers who tested positive for glyphosate in her breast milk , said, "It is frightening to see any glyphosate in my body, especially in my breast milk that will then contaminate my son's growing body. It's particularly upsetting to test positive for glyphosate because I go to great lengths to eat organic and GMO free. I do not consume any meats or seafood and only very rarely eat dairy. This really shows me, and should show others, just how pervasive this toxin is in our food system."So while you may be doing your absolute best to avoid glyphosate or GMOs, you may be slowly poisoning your body and that of your growing child. One study found that pesticides associated with genetically modified foods, such as glyphosate, were detected in the blood of both mothers and unborn children.However, according to Moms Across America Founder and Director Zen Honeycutt, "Moms Across America feels very strongly that breast milk should still be the number one choice for mothers and certainly preferred over GMO soy formula ingredients. We just urge all mothers to eat as organic as possible, especially avoiding meat, dairy, oils and grains that are sprayed with glyphosate at harvest as a drying agent."Feed the World, supported by the Organic Consumers Association, has made the first-ever validated glyphosate testing program for the general public, which is available here: FeedTheWorld.info 1. http://feedtheworld.info 2. http://www.ncbi.nlm.nih.gov 3. http://www.ncbi.nlm.nih.gov 4. http://www.naturalnews.com 5. http://www.sciencedirect.com 6. http://sustainablepulse.com
