Study: EPA-approved GMO insecticide responsible for killing off bees, contaminating entire food chain

Early last year, leaked documents obtained by a Colorado beekeeper exposed the U.S. Environmental Protection Agency’s (EPA) illegitimate approval of clothianidin, a highly-toxic pesticide manufactured by Bayer CropScience that the regulatory agency knew was capable of killing off bees (http://www.naturalnews.com/030921_EPA_pesticides.html). Now, a new study out of Purdue University in Indiana has not only confirmed, once again, that clothianidin is killing off bees, but also that clothianidin’s toxicity is systemic throughout the entire food chain, which could one day lead to the catastrophic destruction of the food supply.
The study, which was published in the online journal PLoS ONE, investigated the various methods and routes by which a class of insecticides known as neonicotinoids, which includes clothianidin, are harming honey bees. They discovered that both clothianidin and thiamethoxam, another component of neonicotinoid insecticides, persist in “extremely high levels” in planter exhaust material produced during the planting of crops treated with these insecticides, which runs contrary to industry claims that the chemicals biodegrade and are not a threat.
The research team also found neonicotinoid compounds in soil, including in fields where the chemicals were not even sprayed, as well as on various plants and flowers visited by bees. Based on their analysis, the researchers involved with the study determined that bees actively transfer contaminated pollen from primarily neonicotinoid-treated corn crops, and bring it back to their hives. The bees also transfer neonicotinoid compounds to other plants and crops not treated with the chemicals, which shows just how persistent these chemicals truly are in the environment.
