Early last year, a leaked document 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.

 

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.

"This research should nail the coffin lid shut on clothianidin," said Laurel Hopwood, chairwoman of the Sierra Club's Genetic Engineering Action Team, who is petitioning the EPA to finally ban these chemicals after years of needless delay.

 

"Despite numerous attempts by the beekeeping industry and conservation organizations to persuade the EPA to ban clothianidin, the EPA has failed to protect the food supply for the American people."

Without bees, which are now dying off at an alarming rate due to exposure to clothianidin and various other insecticides and fungicides, one third or more of the food supply will be destroyed, including at least 100 varieties of fruits and vegetables that rely on bees for pollination.

 

This is why Dr. Neil Carman, Ph.D., scientific advisor to Sierra Club, has put out a call for the EPA to immediately ban the use of clothianidin and the other neonicotinoid insecticides for the sake of protecting the food supply from irreversible destruction.

EPA Document Shows It Knowingly...

Allowed Pesticide That Kills Honey Bees

-   Wik-Bee Leaks   -

The world honey bee population has plunged in recent years, worrying beekeepers and farmers who know how critical bee pollination is for many crops.

 

A number of theories have popped up as to why the North American honey bee population has declined - electromagnetic radiation, malnutrition, and climate change have all been pinpointed.

 

Now a leaked EPA document reveals that the agency allowed the widespread use of a bee-toxic pesticide, despite warnings from EPA scientists.

The document, which was leaked to a Colorado beekeeper, shows that the EPA has ignored warnings about the use of clothianidin, a pesticide produced by Bayer that mainly is used to pre-treat corn seeds. The pesticide scooped up $262 million in sales in 2009 by farmers, who also use the substance on canola, soy, sugar beets, sunflowers, and wheat, according to Grist.

The leaked document was put out in response to Bayer's request to approve use of the pesticide on cotton and mustard.

 

The document invalidates a prior Bayer study that justified the registration of clothianidin on the basis of its safety to honeybees:

Clothianidin’s major risk concern is to nontarget insects (that is, honey bees). Clothianidin is a neonicotinoid insecticide that is both persistent and systemic.

 

Acute toxicity studies to honey bees show that clothianidin is highly toxic on both a contact and an oral basis.

 

Although EFED does not conduct RQ based risk assessments on non-target insects, information from standard tests and field studies, as well as incident reports involving other neonicotinoids insecticides (e.g., imidacloprid) suggest the potential for long-term toxic risk to honey bees and other beneficial insects.

The entire 101-page memo is damning (and worth a read). But the opinion of EPA scientists apparently isn't enough for the agency, which is allowing clothianidin to keep its registration.

Suspicions about clothianidin aren't new; the EPA's Environmental Fate and Effects Division (EFAD) first expressed concern when the pesticide was introduced, in 2003, about the,

"possibility of toxic exposure to non-target pollinators [e.g., honeybees] through the translocation of clothianidin residues that result from seed treatment."

Clothianidin was still allowed on the market while Bayer worked on a botched toxicity study, in which test and control fields were planted as close as 968 feet apart.

Clothianidin has already been banned by Germany, France, Italy, and Slovenia for its toxic effects. So why won't the EPA follow? The answer probably has something to do with the American affinity for corn products.

 

But without honey bees, our entire food supply is in trouble.
