      EPA Allows Continued Sale and Use of Bee Killing Pesticide After Agency Report Shows it Causes Hive Collapse

      Submitted by Annie White on January 8, 2011 – 10:51 pmOne Comment

      A study by the EPA on the pesticide clothianidin which has been used widely in the U.S. though it is banned in France, Itlay and Germany for its toxic effects shows what those countries have known for years. The chemical that is produced by Bayer and used mainly to pre-treat corn seeds is toxic to bees which are attracted to corn. 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. What is worse then this is the EPA knew that clothianidin could be toxic when it came out in 2003, but gave Bayer the go ahead to use the product.

      Bayer was permitted to sell the product and seed processors could freely use it, on the condition that Bayer complete a life cycle study of clothianidin on corn by December 2004. Bayer was granted an extension until May 2005 (and permission to use canola instead of corn in its tests), but didn’t complete the study until August 2007. The EPA continued to allow the sale of clothianidin even though Bayer was not holding up their end of the deal.  Once the Bayer study finally did came out, it was flawed and now the EPA’s own studies done on the product have come forth on wiki-leaks exposing information that originally was ignored. Here is an exert from their report:

      “This compound is toxic to honey bees. The persistance of residues and the expression clothianidin in nectar and pollen suggest the possibility of chronic toxic risk to honey bee larvae and the eventual stability of the hive.”

      Now the EPA has the truth and obviously knows the threat yet somehow this product will be available for sale again in the spring! Ready to poison and degrade the bee pollination for another season. Why is the EPA allowing this to happen? David Hackenberg, the beekeeper who first discovered Colony Collapse Disorder (CCD) doesn’t think that the EPA will take action unless it’s sued by a major environmental organization. This is an agency that is supposed to be protecting our health and environment, why does it only feel spurred to action when citizens organizations move to protest? Hackenberg tells Fast Company that an EPA official recently told him that clothiandin is still on the market in part because of fears that Bayer would sue the agency if it is removed.  Much more to be afraid of from overly powerful corporations who rule with money then to take real action to protect the food supply and the (duh) Environment.

      Without honeybees our entire food supply is in trouble yet the EPA has decided to continue to stand by and watch the poison that is killing them be dumped on fields across the nation. They let Bayer slide on research deadlines and then approved the companies shoddy report. It seems that a German based company would not have much ground to defy decisions made by a U.S. federal agency that is presumably protecting it’s citizens.The EPA should perhaps consider a name change to CPPA, Corporate Profit Protection Agency.

      Beekeepers across the U.S. are reporting record low honey crops as their bees fail to make it through the winter. One-third of American agriculture, which relies on bee pollination, is at stake. And the problem may be at least partially attributable to clothianidin, a Bayer-branded pesticide used on corn and other crops.

      But as we revealed last week, the EPA knew that clothianidin could be toxic when the product came on the market in 2003. So why is it still on the market?

      The bee-toxic pesticide problem can be traced back to 1994, when the first neonicotinoid pesticide (Imidacloprid) was released. Neonicotinoids like imidacloprid and clothianidin disrupt the central nervous system of pest insects, and are supposed to be relatively non-toxic to other animals. But there’s a problem: The neonicotinoids coat plant seeds, releasing insecticides permanently into the plant. The toxins are then released in pollen and nectar–where they may cause bees to become disoriented and die.

      After imidacloprid was released in France (under the name Gaucho) the number of bees in the country dropped rapidly, from 75 kg per hive down to 30 kg per hive between 1995 and 2001. France conducted an official study on the pesticide in 1998, but found no solid evidence that imidacloprid played a part in bee deaths. Nevertheless, Imidacloprid was banned for use on sunflowers and, later, sweet corn.

      Enter clothianidin, a next-generation neonicotinoid released by Bayer in 2003. “In terms of the neonicotonoid family, clothianidin is one of the most toxic members,” explains Dr. James Frazier, a professor of entomology at Penn State’s College of Agricultural Sciences.

      The EPA first brought up the link between clothianidin and bees before the pesticide’s release in February 2003. The agency originally planned to withhold registration of the pesticide because of concerns about toxicity in bees, going so far as to suggest that the product come with a warning label (PDF): “This compound is toxic to honey bees. The persistance of residues and the expression clothianidin in nectar and pollen suggest the possibility of chronic toxic risk to honey bee larvae and the eventual stability of the hive.”

      But in April 2003, the EPA decided to give Bayer conditional registration. Bayer could sell the product and seed processors could freely use it, with the proviso that Bayer complete a life cycle study of clothianidin on corn by December 2004. Bayer was granted an extension until May 2005 (and permission to use canola instead of corn in its tests), but didn’t complete the study until August 2007. The EPA continued to allow the sale of clothianidin, and once the Bayer study finally came out, it was flawed.

      In a statement to the Pesticide Action Network, beekeeper Jeff Anderson explains:

      “The Bayer study is fatally flawed. It was an open field study with control and test plots of about 2 acres each. Bees typically forage at least 2 miles out from the hive, so it is likely they didn’t ingest much of the treated crops. And corn, not canola, is the major pollen-producing crop that bees rely on for winter nutrition.

      “This is a critical point because we see hive losses mainly after over-wintering, so there is something going on in these winter cycles. It’s as if they designed the study to avoid seeing clothianidin’s effects on hive health.” [Emphasis ours]

      The U.S. bee population didn’t start dying off until 2005, says David Hackenberg, the beekeeper who first discovered Colony Collapse Disorder (CCD). “We started seeing problems where bees were disappearing in the fall. We blamed it on mites, viruses and a lot of other stuff because we didn’t know what to blame it on.”

      But soon Hackenberg made the connection: bee die-off seemed to follow corn crop plantings so much that “you can follow the trail of this stuff to where bees are collapsing,” says Hackenberg.

      Frazier first started paying attention to the problem in 2007. “Ever since we started this work, the sheer magnitude of the use of neonicotonoids in the environment has always made them suspect for us,” he explains.

      Frazier and Hackenberg weren’t alone in their concern. Germany suspended the use of neonicotinoids in 2008 after the misapplication of clothiandin by beekeepers in the Baden-Württemberg area caused the pesticide to get into the air. Two-third of the beekeepers’ bees in the region died as a result (tests on dead bees showed that 99% had clothiandin build-up).

      Italy also suspended the use of neonicotinoids in 2008. The country has evidence that the ban is saving bees. In 2009, Italy saw zero cases of bee mortality in apiaries surrounding neonicotinoid-free corn crops. Bee mortality had been an issue around corn crops in the country since 1999.

      The EPA’s response to these suspensions: “Several European countries have suspended the use of certain pesticides in response to incidents involving acute poisoning of honey bees. To EPA’s knowledge, none of the incidents that led to suspensions have been associated withColony Collapse Disorder.”

      And then came last week’s news that the EPA recently conducted another study on clothiandin (PDF) in response to Bayer’s request to use the pesticide on cotton and mustard (the chemical can currently be used on corn, canola, soy, sugar beets, sunflowers, and wheat).

      The new study, unearthed by Colorado beekeeper Tom Theobald, invalidates Bayer’s previous study, claiming that “after another review of this field study in light of additional information, deficiencies were identified that render the study supplemental. It does not satisfy the guideline 850.3040, and another field study is needed to evaluate the effects of clothianidin on bees through contaminated pollen and nectar.” The study also warns that clothiandin is highly toxic to bees on both a contact and oral basis.

      And yet, the EPA is continuing to allow the sale of clothiandin, even though the study that the agency based its decision on proved to be invalid. “It’s a matter of perspective,” says Frazier. “If the core study to judge registration is no longer considered a valid core study, do you allow continued use of something without good scientific data behind it? That’s the choice that’s been left to be made by the EPA.”

      Hackenberg doesn’t think that the EPA will take action unless it’s sued by a major environmental organization (note: in 2008, the NRDC sued the EPA to release Bayer’s studies on neonicotinoid safety). Indeed, Hackenberg tells Fast Company that an EPA official recently told him that clothiandin is still on the market in part because of fears that Bayer would sue the agency if it is removed.

      “I was at the EPA yesterday,” Hackenberg says. “They keep telling us that bee scientists have to prove to the EPA that there’s a problem. The problem is that the EPA is supposed to protect the environment, it’s their responsibility to make sure that the chemical companies are doing their job.”

      No one can say for sure that neonicotinoids alone are causing bees to die off–many more studies have to be done. But the EPA would do well to err on the side of caution for the beekeepers who are rapidly losing their bees. Tom Theobald, for example, saw his smallest honey crop in 35 years of beekeeping, and Hackenberg claims that he has talked to beekeepers across the country who have lost up to 90% of their output this year.

      Is it really worth waiting to find out what happens if the EPA doesn’t take neonicotinoids off the market? There isn’t time to waste. Clothiandin has a half-life of 19 years in heavy soils favored by farmers.

      The EPA has not responded to our requests for comment.
