Appeals Court to Hear Case on EPA’s Registration of Bee-Toxic Chemical

(Beyond Pesticides, March 4, 2015) The 9th U.S. Circuit Court of Appeals has agreed to hear the case brought by beekeepers challenging the U.S. Environmental Protection Agency’s (EPA) approval of a toxic pesticide known to be toxic to bees. In 2013, the beekeepers filed suit against the agency, citing that the new chemical, sulfoxaflor, as further endangering bees and beekeeping and noting that their concerns were not properly addressed by EPA before registration was granted. Sulfoxaflor is a sub-class of the neonicotinoid pesticides that have been linked to global bee declines. The Court has agreed to hear the case on April 14, 2015. The case, Pollinator Stewardship Council v. EPA, which requests changes to EPA’s product label for sulfoxaflor, was first filed July 2013. The petitioners include the Pollinator Stewardship Council, the American Honey Producers Association, the National Honey Bee Advisory Board, the American Beekeeping Federation, and beekeepers Bret Adee, Jeff Anderson and Thomas Smith. The beekeeper groups are represented by Earthjustice. The case is one of a number of pending legal cases on EPA’s pesticide decisions under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), including one submitted March 2013 by Beyond Pesticides, the Center for Food Safety, beekeepers, […]

Over 4 Million People Press Obama to Protect Bees

Congress heeds call to action and introduces legislation as pressure mounts on White House Task Force to issue meaningful recommendations March 4, 2015 (Washington, DC)””A coalition of beekeepers, farmers, business leaders, environmental and food safety advocates rallied in front of the White House and delivered more than 4 million petition signatures today calling on the Obama administration to put forth strong protections for bees and other pollinators. This action anticipates the Pollinator Health Task Force recommendations, expected later this month. The task force, announced by the White House this past June, is charged with improving pollinator health through new agency regulations and partnerships. The assembled groups demand that the recommendations include decisive action on rampant use of neonicotinoids, a class of systemic insecticides scientists say are a driving factor in bee declines. The rally coincided with both a D.C. metro ad campaign and Representatives Earl Blumenauer (D-OR) and John Conyers’s (D-MI) reintroduction of the Saving America’s Pollinators Act, which would suspend the use of four of the most toxic neonicotinoids until the Environmental Protection Agency (EPA) conducts a full review of their safety. Representative Blumenauer, said, “Pollinators are not only vital to a sustainable environment, but key to a stable […]

Over 125 Groups Urge President Obama to Protect Bees and Other Pollinators from Pesticides

(Beyond Pesticides, March 3, 2015) Over 125 conservation, beekeeping, food safety, religious, ethnic and farming advocacy groups are urging President Obama and the Environmental Protection Agency (EPA) to take swift and meaningful action to protect honey bees and other pollinators from toxic pesticides. Groups, including Beyond Pesticides, raised their voice through a letter sent in advance of a pending report from the White House Pollinator Task Force, which was established last June by the President with the goal to “reverse pollinator losses and help respond populations to healthy levels.” Last October the White House announced it would miss its self-assigned deadline, delaying the urgent action that is needed to address this crisis. The letter urges President Obama and executive agencies to take action against a class of pesticides called neonicotinoids, systemic poisons that are devastating bee populations. They are also threatening the nation’s food supply, since one-third of the food consumed in the United States is pollinated by bees. “Through bold and decisive action from the White House and EPA, we can begin to reverse bee declines and protect pollinator populations for future generations,” said Nichelle Harriott, Science and Regulatory  Director at Beyond Pesticides. Among other steps the  letter calls […]

Partial Victory as Hershey’s Announces Move Away from GMO Ingredients

(Beyond Pesticides, March 2, 2015) Amid growing consumer backlash, Hershey’s has announced first steps toward moving to non-genetically engineered (GE) ingredients in its chocolate. The news comes in response to tens of thousands of Facebook posts, emails, and telephone calls from consumers who took part in a campaign calling on Hershey’s to move to non-GE ingredients led by GMO Inside. In a statement released February 18, Hershey’s said that it will “transition some of its most popular chocolate brands, including Hershey’s Kisses Milk Chocolates and Hershey’s Milk Chocolate Bars to simpler ingredients.” Last week, Hershey’s confirmed with GMO Inside that as part of its commitment to simpler ingredients, its two iconic products will be non-GE by the end of the year, however the company did not respond to the request to source its sugar organically. “We congratulate Hershey’s on this important move and great first step. As one of the leading chocolate companies in the U.S., this commitment will help move the rest of the companies in this sector,” said Nicole McCann, Green America Food Campaigns Director, “Hershey’s joins General Mills, Unilever, Post Foods, and other leading companies in responding to consumer demand to make at least some of its […]

New Research Links Bee-Killing Insecticide to Monarch Butterfly Deaths

(Beyond Pesticides, February 27, 2015) New research from the University of Minnesota presents some of the first evidence linking the bee-killing insecticides known as neonicotinoids to monarch butterfly deaths. The study finds that milkweed plants, which monarch butterflies need to survive, may also retain neonicotinoids from nearby plants, making milkweed toxic to monarchs. Monarch population numbers have fallen by 90% in less than 20 years. This year’s population was the second lowest since careful surveys began two decades ago. The critical driver of monarch decline  is the loss of larval host plants in their main breeding habitat, the midwestern Corn Belt. Monarchs lay eggs exclusively on plants in the milkweed family, the only food their larvae will eat. University of Minnesota entomologist Vera Krischik, Ph.D. fed butterflies milkweed plants treated with the neonicotinoid insecticide known as imidacloprid in amounts that might typically be found on backyard plants. While adult monarchs and painted lady butterflies were not affected, which, according to Dr. Krischik, indicates the ability of the adults to detoxify, the larvae of both species of butterflies died. During the course of the study, larvae fed on the treated plants for seven days. “For the monarch, nobody was left that […]

Emergency Use of Bee-Killing Pesticide Approved for Florida Citrus

(Beyond Pesticides, February 26, 2015) Yesterday, the Environmental Protection Agency (EPA) granted Florida citrus growers an emergency exemption to use the bee-killing pesticide clothianidin to control Asian Citrus Psyllid (ACP), a pest that causes “citrus greening,” a devastating citrus plant disease. Clothianidin, which is not currently registered for use on citrus, is part of a class of neurotoxic, systemic insecticides called neonicotinoids, which have been implicated in global honey bee declines and suspended in the European Union. “EPA needs to assist in stopping the deadly use of pesticides that harm bees, butterflies, and birds with sustainable practices, rather than imperil pollinators with its decisions,” said Jay Feldman, executive director of Beyond Pesticides, a health and environmental advocacy group. He continued, “We understand the immediate chemical needs of chemical-intensive agriculture for increasingly toxic and persistent chemicals, but urge EPA to help stop the treadmill, lest it allow irreversible harm to the environment, biodiversity, and human health.” Beyond Pesticides is urging EPA to require that growers adopt a management plan in order to apply clothianidin. “Ultimately, EPA should be requiring growers to adopt integrated organic systems to manage pests, as a part of an emergency permit,” said Mr. Feldman.

Scientists Challenge Industry Consensus that GE Foods Are â€Safe’

(Beyond Pesticides, February 25, 2015) The biotechnology industry behind genetically engineered (GE) foods have for years touted that their technology is safe, dismissing any attempts to challenge their science or regulate their material. However, 300 scientists, physicians and scholars assert there is no scientific consensus on the safety of GE foods and find that claims of safety are an “artificial construct that has been falsely perpetuated” through various forums and media. The statement, published in the journal Environmental Sciences Europe and entitled, “No scientific consensus on GMO safety,” cites a concerted effort by GE seed developers and some scientists, commentators and journalists to construct the claim that there is a “scientific consensus” on GE safety, and that debate on the topic is “over.” According to the 13-page statement, 300 independent scientists and researchers felt compelled to develop a document that offered a balanced account of the current state of dissent in this field, based on published evidence in the scientific literature, for both the interested public and the wider science community. They find that a claim of safety “”¦is misleading and misrepresents or outright ignores the currently available scientific evidence and the broad diversity of scientific opinions among scientists on […]

Will White House Help Bees, as Declines Threaten to Sting Consumers’ Wallets, and States Respond?

(Beyond Pesticides, February 24, 2015) According to recent reports from local California news outlets, Honey Bees are in Short Supply In Central Valley, with the risk that consumers across the United States will be seeing higher prices on fruits, nuts, and vegetables this year as a consequence of declining honey bee populations. The ongoing pollinator crisis has resulted in greater than 30% of managed bee colonies dying off each winter since 2006, an unsustainable rate that will inevitably impact the pocketbooks of consumers in the U.S. and may even ultimately result in global malnutrition. But that doesn’t have to be the outcome. As Beyond Pesticides continues to remind concerned residents, although there are a number of hazards affecting honey bee populations, this crisis is No Longer a Big Mystery. The scientific evidence shows that a class of toxic, persistent, systemic chemicals called neonicotinoids present immense risks to honey bees and other pollinator species. Twenty-nine scientists spanning multiple disciplines analyzed over 800 peer-reviewed papers on the subject came to a similar conclusion. “The assessment found that both individuals and populations can be adversely affected by low or acute exposure making them highly vulnerable. Pollinators exposed to contaminated pollen, nectar and water […]

House Panel Rejects Hawai’i Bill to Impose Pesticide Buffer Zones

(Beyond Pesticides, February 23, 2015) A Hawaii state House agriculture committee rejected a bill Thursday that sought to impose buffer zones for large agricultural companies that spray restricted-use pesticides near schools and other sensitive areas. The proposal, House Bill 1514, introduced by Rep. Chris Lea, stemmed from concerns about  the impact of genetically-engineered (GE) farming and its inherent dependency on increasing  pesticide use. The measure sought  to require companies’  disclosure of the pesticides used and the volume of use. The bill had strong support from the Hawaii chapter of the national nonprofit Center for Food Safety (CFS), as well as a strong backing from neighbor island residents. Maui, Kauai, and the Big Island have all passed laws recently to regulate the seed industry, but a federal  district  court judge  has ruled  that Hawaii counties do not have that power. Industry has been especially effective in obstructing the bill. CFS’ Hawaii director, Ashley Lukens, said after Thursday’s hearing that she was frustrated by the limited amount of time advocates were given to testify. “It was clear from the very beginning that the hearing was intended to allow the industry to reiterate their talking points,” she said. Not surprisingly, companies (like Monsanto) […]

Changes to Canadian Aquaculture Rule Raises Pesticide Concerns

(Beyond Pesticides, February 20, 2015) A broad-based coalition is urging Canada’s Prime Minister Stephen Harper to put a stop to proposed changes to federal aquaculture regulations, citing damage to the environment and existing businesses. The proposed amendments to the federal Fisheries Act would exempt the aquaculture industry from provisions that “prohibit the release of deleterious substances into water frequented by fish.” Coalition members are worried that the changes will result in pesticides routinely being dumped into the Bay of Fundy,  located between the Canadian provinces of Nova Scotia and New Brunswick, and remove Environment Canada’s role in aquaculture activities, said spokeswoman Maria Recchia, the executive director of the Fundy North Fishermen’s Association. Aquaculture, which refers to the breeding, rearing, and harvesting of aquatic organisms such as fish, shellfish, and plants, provides half of the world’s seafood. According to  Food and Water Watch, offshore aquaculture follows an industrial agriculture model which grows thousands of animals in a confined environment. For fish, however, this confined space is in the ocean, meaning all of the waste products from the operation flow directly into the ocean. This includes excess feed and chemicals that are used, such as antibiotics and pesticides, to treat or prevent […]

USDA Approves GE Apple that Won’t Brown

(Beyond Pesticides, February 19, 2015) Last week, regulators at the United States Department of Agriculture (USDA) approved a genetically engineered (GE) apple that does not brown after slicing or bruising. The “Arctic” apple, produced by Okanagan Specialty Fruits, is engineered using a novel technique called RNA interference (RNAi). In the case of this GE apple, RNAi technology has been used to silence the genes that produce polyphenol oxidase (PPO), the enzymes responsible for the browning that results after an apple has been bruised. Government approval of this method of genetic engineering is raises serious concerns because of considerable uncertainty regarding the unintended effects of this technology. These concerns are compounded by the agrochemical industry’s future interests in using RNAi technology to control crop pests. So far, USDA has approved commercial use of Granny Smith and Golden Delicious “Arctic” apples, and the company plans to produce Gala and Fuji cultivars in the future. Beyond the questionable utility of an apple that does not brown, are the health and economic risks associated with the apple’s commercial production and use. Some opposing the GE apple have dubbed it the “botox apple” as it can give apples  the appearance of being fresh long after […]

2,4-D and Atrazine Effects on Endangered Species Focus of Another Lawsuit

(Beyond Pesticides, February 17, 2015) The Center for Biological Diversity filed a lawsuit in federal court in California February 12 against the U.S. Fish and Wildlife Service (FWS) for failing to ensure that three widely used pesticides ””atrazine, 2,4-D and alachlor”” do not jeopardize the survival of two Bay Area endangered species, the delta smelt and Alameda whipsnake. FWS has yet to act on a request from the U.S. Environmental Protection Agency (EPA) to determine whether measures are needed to protect the delta smelt and Alameda whipsnake from exposure to these pesticides. “These pesticides are known to harm wildlife even in miniscule amounts, so it’s long past time that we start taking commonsense steps to protect endangered species, our water and ourselves,” said Brett Hartl, endangered species policy director at the Center. “Putting off any analysis of the harms caused by pesticides for six years is simply unacceptable, and has set back the recovery of these two species substantially.” Scientific research has shown that atrazine can harm the development of amphibians at exposures of just a few parts per billion, is toxic to fish, reptiles, mammals and birds, and may elevate risks of birth defects in people. Up to 80 […]

EPA Sued for Violating Endangered Species Act with Allowance of New 2,4-D/Roundup Pesticide

(Beyond Pesticides, February 13, 2015) With the U.S. Environmental Protection Agency’s (EPA)  nod to the pesticide industry on expanded uses of the herbicides 2,4-D and glyphosate, environmental groups are charging that the agency violated the Endangered Species Act (ESA).  Repeating a pattern of putting the environment in harm’s way through violations of  federal endangered species  law, a lawsuit filed Friday  documents   EPA’s  failure to consult with the U.S. Fish and Wildlife Service (FWS) regarding the impact of the herbicide on two endangered species —the whooping crane and the Indiana bat— with the recent approval of Dow AgroSciences’ herbicide, Enlist Duo, for use on genetically engineered (GE) crops in six midwestern states. Enlist Duo is an herbicide that incorporates a mix of  glyphosate  and a new formulation of  2,4-D, intended for use on GE Enlist Duo-tolerant corn and soybean crops. Approved for use on GE corn and soybeans that are engineered to withstand repeated applications of the herbicide, the creation of 2,4-D-tolerant crops and EPA’s approval of Enlist Duo is the result of an overuse of glyphosate, an ingredient in Monsanto’s Roundup. The misuse resulted in an infestation of glyphosate-resistant super weeds which can now be legally combatted with the […]

Bill Introduced to Protect Oregonians from Forestry Pesticide Use

(Beyond Pesticides, February 12, 2015) Oregon Senator Michael Dembrow (D-Portland) and Representative Ann Liniger (D-Lake Oswego) introduced a bill on Tuesday targeting the loosely regulated aerial pesticide spraying practices of the Oregon timber industry. The bill will establish residential, school, drinking water, and fish habitat buffers zones, require timely notification of spraying and controlled burns for nearby residents, increase record keeping requirements, establish protected areas where pesticide spraying is prohibited, and grant investigative and enforcement authority to the Oregon Health Authority in cases of human pesticide exposure. Development of the bill grew out of a series of incidents across Oregon involving residential pesticide exposure and poisoning from aerial spraying of forest lands. The main incident, which spurred state-wide outrage and investigations into the pesticide regulation and enforcement practices of the Oregon Department of Agriculture (ODA), involved Curry County residents who complained of pesticide exposure after witnessing aerial spraying near their homes. After pressure from local residents, investigative reporters, and environmental groups, ODA was ordered to publicly disclose pesticide records. It was found that the pesticides being sprayed were 2,4-D and triclopyr  ””information that conflicted with previous statements and reports and adding to the trend of opaque and lackluster ODA enforcement […]

France Elevates Effort to Reduce Pesticide Use by 50%, but Delays Deadline

(Beyond Pesticides, February 11, 2015) In 2008, France announced it would voluntarily cut pesticide use by 50 percent by 2018, and emerged as the European leader in  reducing pesticide dependency. With its plan faltering, the European Union’s (EU) biggest agricultural producer and pesticide user has announced the expansion of  a network of pioneer farms experimenting with alternative techniques and mandated reductions in pesticide sales as it  delays its target reduction until 2025. The French government has pushed back to 2025 the timeline for halving pesticide use and added an intermediate target of a 25 percent fall by 2020, Agriculture Minister Stephane Le Foll said. The  2018 target was slated as voluntary, but pesticide use has actually increased, in part due to poor weather, according to French officials. As the EU’s top agricultural producer, France is trying to become less dependent on pesticides, which are known to pose various health and environmental risks. The targets for pesticide reduction remain mostly non-binding on farmers, but Minister Le Foll said his revamped plan would encourage a change in practices by expanding their focus on  alternative techniques. The minister notes that farmers need training  in best practices to replace the massive use of pesticides […]

Neonics Harm Bees’ Brain Cells, According to Researchers

(Beyond Pesticides, February 10, 2015) Scientists at the Universities of Dundee and St. Andrews in Scotland have found evidence confirming that the levels of neonicotinoid (neonic) pesticides bees are likely to encounter in the wild impair the pollinator’s brain cells, resulting in colony declines. Bees and other wild pollinators provide services of over $125 billion globally, but are experiencing widespread and consistent losses that have the potential to increase global malnutrition and disease if not properly addressed. Although countries and regions across the globe have taken action to suspend or restrict the use of neonic pesticides in light of their threat to bees, policymakers in the U.S. continue to delay, impose inadequate changes, or even introduce new bee-toxic chemicals. The recent study, Chronic exposure to neonicotinoids increases neuronal vulnerability to mitochondrial dysfunction in the bumblebee (Bombus terrestris), published in the Journal of the Federation of American Societies for Experimental Biology, finds a mechanistic explanation for previous findings that observed poor navigation and foraging in colonies of bumblebees exposed to neonicotinoids. To do this, researchers exposed bumblebees to doses of the neonics imidacloprid and clothanidin generally expected to be seen in the field (10 nanomoles[nM]/2.1ppb), and measured the amount that accumulated […]

Monsanto’s Roundup Eradicates Milkweed, Major Food Source for Monarch Butterflies

(February 9, 2015, Beyond Pesticides) A report, Monarchs in Peril: Herbicide-Resistant Crops and the Decline of Monarch Butterflies in North America, released by Center for Food Safety (CFS) last week, reveals the devastating  impact of Monsanto’s and the nation’s biggest selling herbicide, Roundup (glyphosate), on the survival  of monarch butterflies. The herbicide is  used to treat  millions of acres of herbicide-tolerant  genetically engineered (GE) crops, eliminating the monarchs’ sole source  of food, milkweed, and approaching  a collapse of their population, which has plummeted over the past 20  years. The report cites findings that  glyphosate use on Roundup Ready  (glyphosate-tolerant) crops has nearly eradicated milkweed around farmland in the monarchs’ vital midwest breeding ground. At the urging of scientists and public interest groups, the U.S. Fish and Wildlife Service (FWS) is currently considering listing the monarch as a threatened species under the Endangered Species Act (ESA). “This report is a wake-up call. This iconic species is on the verge of extinction because of Monsanto’s Roundup Ready crop system,” said Andrew Kimbrell, executive director at Center for Food Safety. “To let the monarch butterfly die out in order to allow Monsanto to sell its signature herbicide for a few more years is […]

People Who Eat Organic Have Lower Pesticide Levels in Their Bodies

(Beyond Pesticides, February 06, 2015) People who eat an organic diet have lower levels of pesticides in their bodies than those who eat conventional fruits and vegetables grown with pesticides, according to a new study published yesterday.  The study, “Estimating Pesticide Exposure from Dietary Intake and Organic Food Choices: The Multi-Ethnic Study of Atherosclerosis (MESA),” published in the journal Environmental Health Perspectives, looks at adult exposure to organophosphate pesticides (OPs). Scientists studied nearly 4,500 people from six U.S. cities and examined long-term dietary exposure to 14 OPs. This study group  was restricted to those who reported rarely or never eating organic food (“conventional consumers”). Scientists looked for signs of organophosphate exposure via urinary dialkylphosphate (DAP) levels and compared these levels to those who reported organic produce consumption habits. The scientists found that people who reported eating organic fruits and veggies at least occasionally had significantly lower DAP, or organophosphate residue, levels in their urine when compared to people who almost always ate conventionally grown produce. OPs are the most commonly used insecticides on conventional fruits and veggies, thus making OP exposure extremely prevalent. In fact, metabolites of organophosphate metabolites have been found in the urine of over 75 percent of […]

Investigation Finds Industry Efforts to Quash Science and EU Ban of Endocrine Disruptors

(Beyond Pesticides, February 5, 2015) A brewing  battle in the European Union (EU) over removing from the market  Endocrine Disrupting Chemicals (EDC)s has  heated up. An investigative report in  The Guardian  reveals that a European Union (EU) scientific paper, prepared to assist in the development of new mandatory EDC risk assessment standards, was never made public. According to the report, EU Commission sources say the release of the paper was quashed as a result of chemical industry pressure and political influence. At the core of the debate lies two EU regulations, one concerning biocidal products (EU 528/2012) and the second on “plant pest protectants” (EU 1107/2009). Both of these regulations required the EU Commission to produce draft measures concerning specific scientific criteria for the determination of endocrine disrupting properties by December 14, 2013. Under the regulations, chemicals within the biocidal and plant pest protectant categories that are  categorized as having endocrine disrupting properties that may cause adverse effects in humans would be prohibited from use in the market place. As noted in the purpose and subject matter of the biocidal regulations, “The purpose of [the] Regulation is to improve the functioning of the internal market through the harmonization of the […]

Maui Decision Not to Defend GE Moratorium Disappoints Activists

(Beyond Pesticides, February 4, 2015)    In the face of a challenge from the chemical industry, Hawaii’s Maui County will not defend a moratorium on genetically engineered (GE) farming that was passed by county voters last fall. Seeking to have the moratorium thrown out, industry giants Monsanto, Dow-owned Agrigenetics and others sued Maui days after the measure was passed.   It was expected that the county would defend the law in the courts, but to the disappointment of many, attorneys for Maui County filed a single sentence brief with the court, stating that it “is taking no position.” In November 2014, Maui residents passed a ballot initiative prohibiting the growth, testing or cultivation of GE crops in Maui County until an environmental and public health study can show that the planting operations are safe for the community. Now residents and local groups supporting the new law are expressing outrage and disappointment over the decision by Maui County to disregard its duty to defend a law passed by its citizens, despite earlier assurances that county will implement the moratorium. Maui County spokesman Rod Antone said that the outrage from activists groups is misplaced. In December, the court allowed the local group, […]

Commonly Used Pyrethroid Pesticide Increases Risk of ADHD

(Beyond Pesticides, February 2, 2015) A study led by a Rutgers University research team finds that the commonly used pesticide deltamethrin increases the risk of attention deficit hyperactivity disorder (ADHD) in children, adding to a mounting body of scientific research linking pesticide exposure to the disorder. Rutgers scientists, along with colleagues from Emory University, the University of Rochester Medical Center, and Wake Forest University discovered that mice exposed to the pyrethroid insecticide deltamethrin in utero and through lactation exhibit several features of ADHD, including dysfunctional dopamine signaling in the brain, hyperactivity, working memory, attention deficits and impulsive-like behavior. The study, Developmental pesticide exposure reproduces features of attention deficit hyperactivity disorder, was published Wednesday in the Journal of the Federation of American Societies for Experimental Biology (FASEB). ADHD is estimated to affect 8—12% of school-age children worldwide. ADHD is a complex disorder, and though is strong scientific evidence that genetics play a role in susceptibility to the disorder, no specific gene has been found that causes ADHD and scientists believe that environmental factors, such as pesticide exposure, may contribute to the development of the behavioral condition. “Although we can’t change genetic susceptibility to ADHD, there may be modifiable environmental factors, including […]

Persistent Organic Pollutants, Pesticides Linked to Early Menopause

(Beyond Pesticides, January 30, 2015) Extensive exposure to common chemicals may be linked to an earlier start of menopause, according to a new study out of Washington University School of Medicine in St. Louis. Researchers of the study found that women whose bodies have high levels of these chemicals, including three pesticides, experience menopause two to four years earlier than women with lower levels of the chemicals.
