(Beyond Pesticides, April 14, 2011) Researchers at the University of South Florida have discovered that the most widely used fungicide in the U.S., chlorothalonil, is lethal to frogs even at low doses. Chemical pollution, according to the researchers, is considered the second greatest threat to aquatic and amphibious species in the U.S. Because many vital systems of amphibians are similar to those in humans, researchers believe that amphibians may be an underused model for studying the impacts of chemicals in the environment on human health and set out to quantify amphibian responses to chlorothalonil. The study, lead by Teagan McMahon, PhD, was published in Environmental Health Perspectives and opens the door for researchers to quantify the effects of the chemical on other species as well as other toxic pesticides on amphibian populations and human health. Researchers looked at Rana sphenocephala (Southern leopard frog) and Osteopilus septentrionalis (Cuban treefrog) in outdoor aquatic mesocosms (experimental water enclosures) with and without the expected environmental concentration as well as twice the amount of chlorothalonil. They also conducted two dose-response experiments on O. septentrionalis, Hyla squirella (squirrel treefrog), H. cinerea (green treefrogs), and R. sphenocephala, evaluating the effects of the fungicide on the stress hormone […]

(Beyond Pesticides, March 29, 2011) According to a French study published March 2, 2011 in the online edition of Environmental Health Perspectives, prenatal exposure to the herbicide atrazine is linked to small head circumference and fetal growth restriction. The authors say the study “raises particular concerns for countries where atrazine is still in use.” Atrazine is a widespread contaminant in drinking water and is linked to various birth defects, endocrine disruption and cancer, even at concentrations below EPA standards. Although it has been excluded from re-registration in the European Union because it is found above allowable thresholds in groundwater, it is still one of the most widely used herbicides in the U.S. and around world. The study, “Urinary Biomarkers of Prenatal Atrazine Exposure and Adverse Birth Outcomes in the PELAGIE Birth Cohort,” used a case-cohort design nested in a prospective birth cohort conducted in the Brittany region from 2002 through 2006. It collected maternal urine samples to examine pesticide exposure biomarkers before the 19th week of gestation. Quantifiable levels of atrazine were found in urine samples from 5.5% of 579 pregnant women, and various metabolites were identified in 20-40% of samples. The presence versus absence of quantifiable levels of atrazine […]

(Beyond Pesticides, March 23, 2011) According to the Cornucopia Institute, the United States Department of Agriculture (USDA) has confirmed that it will allow products containing unapproved synthetic additives in processed food labeled “organic” for an indefinite grace period. The National Organic Standards Board (NOSB) is slated to take up the issue at its upcoming meeting in April, when it will determine whether the use of these synthetic materials meets the standards of the Organic Foods Production Act nad its standards of health and environmental protection. Consumers are urged to make their voices heard with comments to the NOSB before the April 10 deadline (see below). The Cornucopia Institute has filed legal complaints against infant formula manufacturers and Dean Foods, manufacturer of Horizon dairy products, for adding unapproved additives: Martek Biosciences Corporation’s omega-3 and omega-6 fatty acids (DHA/ARA), derived chemically from fermented algae and fungus, to foods with the organic label. The Cornucopia Institute maintains, and the USDA reiterated in a compliance letter issued March 16, that these additives are illegal in organics. But USDA also stated it would not take enforcement action at this time. The USDA’s compliance letter suggested that it would allow companies to continue adding the additives […]

(Beyond Pesticides, March 18, 2011) As a result of recent court mandated consultations under the Endangered Species Act (ESA) concerning pacific salmon and steel head, the U.S. Environmental Protection Agency (EPA) in a letter to the National Research Council (NRC) is requesting the convening of a committee of independent experts to assist in the review of special scientific and technical issues that have arisen as the agency attempts to stem the impact of pesticides on these endangered species. Citing issues of scientific complexity and high importance, the letter authored by EPA Administrator Lisa Jackson, requests on behalf of the EPA, the Fish and Wildlife Service and the National Marine Fisheries Service (NMFS), a “concerted, closely coordinated effort” to address these issues openly and actively. NRC’s assistance is sought due to the number of complex scientific issues brought to the attention of the agencies as they complete consultations under the ESA concerning the impact of pesticides on endangered salmon and steelhead. Even though calls for EPA to holistically review pesticides have been made by scientists and the environmental community before, EPA is now seeking advice in assessing the effect of pesticides and other Federal Insecticide, Fungicide and Rodenticide Act (FIFRA)-related actions […]

(Beyond Pesticides, March 16, 2011) Congresswoman Louise Slaughter (D-NY) introduced legislation last week that seeks to help protect Americans from widespread antibiotic overuse in food animal production. Antibiotic use in agriculture, as well as in antimicrobial soaps containing materials such as triclosan, offer little to no benefit for public health, but instead contributes to increases in the growth of resistant bacteria. This makes antibiotic and antibacterial resistance a national health concern, due to the fact that it can make infections difficult or impossible to treat. Rep. Slaughter’s bill, H.R. 965 — the Preservation of Antibiotics for Medical Treatment Act, would preserve the effectiveness of antibiotics used to treat human disease by requiring the Food and Drug Administration (FDA) to revoke approval of antibiotics for non-therapeutic purposes unless the agency determines that the drugs do not produce unsafe levels of antibiotic resistance. The bill would allow farmers to continue to treat sick animals with antibiotics. “Antibiotic resistance is a major public health crisis, and yet antibiotics are used regularly and with little oversight in agriculture,” said Rep. Slaughter. The main culprits are confined animal feeding operation (CAFO) operators that routinely add human antibiotics to livestock feed for non-therapeutic purposes, such as […]

(Beyond Pesticides, March 15, 2011) Following the U.S. Environmental Protection Agency’s (EPA) January 10th announcement that it plans to cancel all allowable pesticide residue levels (tolerances) of the toxic fumigant sulfuryl fluoride–effectively banning its use, the chemical’s manufacturer, Dow AgroSciences, is petitioning EPA to launch a formal registration cancellation hearing under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). EPA decided to cancel the tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA) after determining that when residues on food products are combined with fluoridated drinking water and toothpaste, public exposure levels are too high. The agency took the action in response to a June 2006 petition submitted by Fluoride Action Network, Beyond Pesticides, and Environmental Working Group. Food Quality Protection Act of 1996 (FQPA) amendments to FFDCA require that a pesticide registered for use by EPA cannot exceed acceptable risk thresholds when its dietary and nondietary uses are evaluated in the aggregate. Environmentalists believe that the January 2011 sulfuryl fluoride decision was the first time EPA action has resulted in a comprehensive pesticide cancellation of agricultural uses (as distinct from a voluntary cancellation by the manufacturer) because of unacceptable aggregate exposure. While cancellation hearings are not provided under […]

(Beyond Pesticides, March 14, 2011) Scientists working for the United Nations (UN) reveal in a report published March 10, 2011 that the collapse of honeybee colonies is now a global phenomenon that could have devastating consequences. Declines in managed bee colonies, seen increasingly in Europe and the US in the past decade, are now being observed in China, Japan and Egypt according to the report, “Global Bee Colony Disorders and other Threats to Insect Pollinators,” from the United Nations Environment Programme (UNEP). In the UNEP report, leading honeybee experts in the world stress that the potentially disastrous decline in bees —which are a vital pollinating element in food production for the growing global population””is likely to continue unless humans profoundly change their ways from the use of insecticides to air pollution. “The way humanity manages or mismanages its nature-based assets, including pollinators, will in part define our collective future in the 21st century,” UNEP Executive Director Achim Steiner said. “The fact is that of the 100 crop species that provide 90 per cent of the world’s food, over 70 are pollinated by bees.” “Human beings have fabricated the illusion that in the 21st century they have the technological prowess to […]

(Beyond Pesticides, March 10, 2011) The American Public Health Association (APHA) recently adopted 17 new policies at its 138th Annual Meeting in Denver, addressing a broad range of public health concerns, including a new policy calling for greater government action to protect the public from endocrine-disrupting chemicals (EDCs). The policy statement follows official positions released earlier in 2010 by both the American Medical Association (AMA) and the Endocrine Society in that more needs to be done to protect the public from endocrine-disrupting chemicals, or those that interfere with hormone action. Specifically, APHA urges: ”¢ Support for the Endocrine Society and the American Medical Association in proclaiming that more needs to be done to protect the public from potential health risks of exposure to EDCs. ”¢ That given the magnitude and urgency of the public health threat and the recognition that collectively EDCs likely will have common or overlapping effects on the endocrine system, steps should therefore be taken by federal agencies with regulatory oversight for various individual EDCs to coordinate and find synergies among themselves to coordinate and find synergy among federal agencies with regulatory oversight over various individual EDCs. ”¢ Health professionals and scientists with expertise in various aspects […]

(Beyond Pesticides, March 9, 2011) A recent study reports that the underlying cause of a fatal outbreak of P. aeruginosa in a hospital came from the contamination of triclosan soap dispensers, which acted as a continuous source of the bacterium. The contaminated triclosan soap infected the hands of health care workers and then patients, since triclosan is shown to have no effect on P. aeruginosa -a bacterium frequently associated with hospital-acquired infections. Authors of the study recommend alcohol-based sanitizers where appropriate, instead of triclosan soaps. The study, “Molecular Epidemiology of a Pseudomonas aeruginosa Hospital Outbreak Driven by a contaminated Disinfectant-Soap Dispenser,” published online in PLoS One, investigates a fatal epidemic of P. aeruginosa that occurred in a hematology unit in Italy. The researchers found that patients became indirectly infected (e.g., during central venous catheter handling through contaminated items) and the triclosan soap dispenser acted as a common continuous source of P. aeruginosa infection. Since P. aeruginosa is intrinsically not susceptible to triclosan, the use of triclosan-based disinfectant formulations should be avoided in those health care settings hosting patients at high risk of P. aeruginosa infection, the authors conclude. Immunocompromised patients, especially chemotherapy patients, are especially at risk. Soap dispensers in […]

(Beyond Pesticides, March 8, 2011) Leading up to the 29th National Pesticide Forum in Denver, Beyond Pesticides and the Denver Botanic Gardens will be hosting a free screening of the award-winning film Vanishing of the Bees on Wednesday, April 6th, 7:00pm at the Denver Botanic Gardens (1007 York Street). The film, which is narrated by Ellen Page, takes a piercing investigative look at the economic, political and ecological implications of the worldwide disappearance of the honeybee and empowers the audience to fight back. Join us for the film Wednesday evening, and then learn more about Colony Collapse Disorder at the National Pesticide Forum at the Colorado School of Public Health, Friday evening and Saturday, April 8-9. The film is free. Register for the conference online. Film Synopsis Honeybees have been mysteriously disappearing across the planet, literally vanishing from their hives. Known as Colony Collapse Disorder, this phenomenon has brought beekeepers to crisis in an industry responsible for producing apples, broccoli, watermelon, onions, cherries and a hundred other fruits and vegetables. Commercial honeybee operations pollinate crops that make up one out of every three bites of food on our tables. Vanishing of the Bees follows commercial beekeepers David Hackenberg and Dave […]

(Beyond Pesticides, March 07, 2011) To mark International Women’s Day on March 8, members of the international peasant movement Via Campesina demonstrated last week in six Brazilian states. Using the slogan “Women Against the Violence of Agribusiness and Agrotoxins For Land Reform and Food Sovereignty,” they marched together with other organizations working for the rights of women and the rural population. It is important to note that several diseases that are found predominantly in women are highly linked to exposure of pesticides such as female reproductive tract abnormalities, breast cancer and thyroid disease. According to the Brazilian Crop Protection Association (AENDA), which represents producers of farm chemicals, Brazil uses more than one billion liters of agricultural chemicals a year, making it the top consumer country since 2009 of weed killers and insecticides that have toxic effects to humans and wildlife. Amanda Matheus of the Landless Rural Workers Movement told Inter Press Service (IPS) that the use of agrochemicals harmful to the environment is based on an agricultural production model biased towards agribusiness or large-scale export-oriented agricultural production. The model “is driven by an alliance between large landowners and transnational corporations that gain control of the land and invest in monoculture […]

(Beyond Pesticides, March 1, 2011) As insect resistance to pesticides steadily increases, and the underlying conditions of poverty, poor water management, and indecent living conditions contribute to the spread of malaria, the search for silver bullet solutions escalates. Researchers are exploring genetic engineering as the next frontier for a product-based approach to fighting malaria, which annually kills nearly one million people worldwide. While releasing genetically engineered organisms into the environment raises serious concerns that must be fully studied, some in the public health community believe this could help slow the spread of malaria as part of an integrated campaign. At the same time, the long-term underlying causes that support the spread of malaria must be addressed. The new research indicates that a genetically engineered fungus carrying genes for a human anti-malarial antibody or a scorpion anti-malarial toxin could be an effective tool for combating malaria, at a time when the effectiveness of current pesticides against malaria mosquitoes is declining. The researchers also say that this general approach could be used for controlling other devastating insect and tick bug-borne diseases, such as or dengue fever and Lyme disease. “Though applied here to combat malaria, our transgenic fungal approach is a very […]

(Beyond Pesticides, February 28, 2010) The European Union (EU) standing committee on Tuesday decided to allow a 0.1 percent contamination threshold for unauthorized Genetically Engineered (GE) products in animal feed imports that would change the bloc’s zero-tolerance attitude toward biotech food. The EU Commission and Parliament are expected to accept the rule by this summer. If the vote is allowed through by the European Parliament and Council, those shipments could contain GE seeds that are authorized in their home country but may not even have been tested in Europe. Greenpeace spokesperson Stefanie Hundsdorfer warned that the new rules are possibly the first of many concessions to come. “Setting a tolerance threshold, however low, is a sign that Europe is losing control over its own food production to please American exporters,” said Ms. Hundsdorfer. “The danger now is that EU countries come under pressure from the pro-GE lobby to also allow GE contamination in food products for direct human consumption.” According to industry, exporting states and the European Commission say the new concession is necessary to prevent supply disruptions, because the EU’s feed industry relies on imports for 80% of its needs, and the world’s largest suppliers””Argentina, the United States and […]

(Beyond Pesticides, February 23, 2011) In response to a request by beekeepers and environmentalists to remove a pesticide linked to Colony Collapse Disorder (CCD), the U.S. Environmental Protection Agency (EPA) in a letter, defended the pesticide clothianidin and the scientific study in question which was identified by beekeepers as a critically flawed study. EPA states that it does not intend to suspend or cancel clothianidin, even though independent studies have linked this chemical and others in its class to bee decline. Beyond Pesticides, as a part of a group of environmentalists and beekeepers, broke the news last December that a core study underpinning the registration of the insecticide clothianidin was unsound, citing leaked EPA memos which discloses the critically flawed scientific study and its reclassification as a “core” study on which clothianidin’s conditional registration was contingent on, to a “supplemental” study. Bayer CropSceicne, manufacturer of clothianidin designed and submitted to study to EPA as part of clothianidin’s registration requirement. Beekeepers claim that the initial field study guidelines, which the Bayer study failed to satisfy, were insufficiently rigorous to test whether or not clothianidin contributes to CCD in a real-world scenario: the field test evaluated the wrong crop, over an insufficient […]

(Beyond Pesticides, February 18, 2011) The Danish government has announced that it has reached an agreement that aims to phase out pesticide use on golf courses throughout the country. The agreement, which was made between the Danish Government, the Danish People’s Party, the Social Democrats, the Socialist People’s Party and the Danish Social-Liberal Party, seeks to replace the present ”Agreement on the golf courses of the future” dating from June 2005. It states that the long-term objective is a phasing-out of the consumption of pesticides on Danish golf courses coupled with increases in education regarding pesticide-neutral care utilizing alternative methods, such as mechanical weed control. Part of the agreement involves an evaluation of the results achieved so far, to be carried out before the end of 2014, in order to inform efforts to tighten the requirements. The partial aim of the 2005 agreement was that, before the end of 2008, the use of pesticides on golf courses should be reduced to 0.1 kg of active ingredient per hectare (ha). As part of the 2005 agreement, golf courses were to submit their pesticide use data in the form of annual “green accounts” to The Danish Golf Union, which has advocated for […]

(Beyond Pesticides, February 17, 2011) According to a recent investigative report, a company known for conducting scientific research for the pesticide industry has, in an attempt to refute research linking pesticides to Parkinson’s disease, paid a U.S. government agency, the National Institute for Occupational Safety and Health (NIOSH), to prove that certain pesticides are safe. According to the report, the company, Exponent Inc., is a member of CropLife America, a trade group that represents pesticide manufacturers, and also has worked regularly for Syngenta, which makes paraquat, one of the chemicals it is looking prove as safe. Specifically, the company is looking to refute the research which shows that even small amounts of agricultural chemicals, maneb and paraquat, when combined, can raise the risk of Parkinson’s disease. According to the report, managing scientist of Exponent, Laura McIntosh, PhD, said in an interview that the company donated the money and sought participation at NIOSH to enhance the credibility of its study of maneb and paraquat; they wanted to make their research “bulletproof.” NIOSH is a division of the Centers for Disease Control and Prevention (CDC). Generally, government agencies are supposed to be unbiased, and federal ethics rules prohibit employees from accepting money […]

(Beyond Pesticides, February 16, 2011) Many agricultural pesticides —including some previously untested and commonly found in food— disrupt male hormones, according to new tests conducted by British scientists. Meanwhile, U.S. researchers at the National Institutes of Health have found that people who used two specific varieties of pesticide were 2.5 times as likely to develop Parkinson’s disease. Pesticides Impact Male Hormones Evidence suggests that there is widespread decline in male reproductive health and anti-androgenic pollutants, also known as endocrine disruptors, may play a significant role. Thirty out of 37 pesticides tested by the researchers at the University of London altered male hormones, including 16 that had no known hormonal activity until now. There was some previous evidence for the other 14. Most are fungicides applied to fruit and vegetable crops, including strawberries and lettuce. The study, “Widely Used Pesticides with Previously Unknown Endocrine Activity Revealed as in Vitro Anti-Androgens,” is published in Environmental Health Perspectives. The British researchers screened the chemicals using in vitro assays, which use human cells to check whether the pesticides activate or inhibit hormone receptors in cells that turn genes on and off. Scientists, however, are uncertain what actually happens in the human body at the […]

(Beyond Pesticides, February 10, 2011) Despite the numerous scientific data on the devastating health and environmental consequences of endosulfan —a pesticide so toxic that is banned in over 60 countries including the U.S., officials in India say that a ban on the widely used chemical would put the country’s food security at risk and harm the welfare of farmers. However, thousands of villagers in Kerala, India, who have become disabled due to the use of the pesticide, pushed for a state ban in 2004 and have since joined the global movement to ban endosulfan. Doctors say that over 550 deaths and health problems in over 6,000 people in the region are related to the aerial spraying of the pesticide over cashew farms between 1979 and 2000. “Six thousand patients living with disabilities is not enough scientific evidence to enforce a national ban?,” asked B.C. Kumar, to the Washington Post. Kumar’s father, a cashew farm laborer, died of cancer. The endosulfan industry in India is estmiated to be worth over $100 million, making it the world’s largest producer, exporter and user of the product. The three companies that produce the product in India, including one that is partially government-owned, claim that […]

(Beyond Pesticides, February 8, 2011) Research published February 7, 2011 in the online edition of the journal Peditatrics shows that children more highly exposed to pyrethroid insecticides and piperonyl butoxide (PBO), a synergist added to increase the potency of pyrethroids, are three times as likely to have a mental delay compared to children with lower levels. The study, “Impact of Prenatal Exposure to Piperonyl Butoxide and Permethrin on 36-Month Neurodevelopment,” measured exposure to pesticides using maternal and umbilical cord plasma samples and in personal air samples, collected using backpack air monitors during pregnancy. Children were then tested for cognitive and motor development (using the Bayley Scales of Infant Development) at three years of age. Children with the highest prenatal exposures scored about 4 points lower on the test. That’s about the same intelligence loss caused by lead, Philip Landrigan, MD, a pediatrics professor and environmental health expert at New York’s Mount Sinai School of Medicine, told USA Today. Pyrethroid pesticides kill bugs by “being toxic to the developing brain,” Dr. Landrigan says. The results are “very believable and should be taken seriously.” Pyrethroid pesticides have increased in popularity over the past decade due in large part to the phase-out of […]

(Beyond Pesticides, January 26, 2011) California’s Department of Toxic Substances Control (DTSC) is asking in-state nanotechnology companies and researchers to share how they’re keeping tabs on several nano-sized metals, as evidence continues to emerge that these substances may have long-term implications for the environment. Nano-sized materials, now incorporated into many consumer products including paper wrapping, clothing and cosmetics, are currently not regulated and have not been assessed for hazards that have the potential to impact public health and the environment. Late last month, the DTSC put out a request for information about nano-sized silver, zero valent iron, titanium dioxide, zinc oxide, cerium oxide and quantum dots. Specifically, the agency wants to know what tools companies and researchers are using to analyze these materials””a key question for regulators across the country in the effort to understand the impact of the substances””over a broad range of areas, including air, water, soil, sewage sludge and urine. Nanotechnology, which capitalizes on unique properties of super-small particles, is already in use in manufacturing items like bike frames, skin creams and cancer treatments. As these tiny materials hit the market, there are huge gaps in what scientists know about their properties. Jeffrey Wong, DTSC’s chief scientist, […]

(Beyond Pesticides, January 25, 2011) Research by the U.S. Department of Agriculture’s (USDA) Bee Research Laboratory and Penn State University shows that the neonicotinoid insecticide imidacloprid contribute —at extremely low levels— to bee deaths and possibly colony collapse disorder (CCD), the widespread disappearance of honey bees that has killed off more than a third of commercial honey bees in the U.S. While the study has not been published yet, the UK’s The Independent newspaper reports that honeybees exposed to imidacloprid are more susceptible to the fungal pathogen Nosema. This is the first study to show that neonicotinoids impact the survival of bees at levels below the level of detection, meaning that field studies would not have considered the role of the pesticide, because they would not have detected it. USDA researcher Jeffrey Pettis, PhD and Penn State University researcher Dennis Van Engelsdorp, PhD explained their research in the 2010 documentary, The Strange Disappearance of the Honeybees (transcript courtesy of Grist.org): [Pettis] I’ve done a recent study actually in collaboration with Dennis van Engelsdorp and some other researchers, where we exposed whole colonies to very low levels of neo-nicotinoids in this case, and then ”˜challenged’ bees from those colonies, with Nosema […]

(Beyond Pesticides, January 20, 2011) Beyond Pesticides and the National Organic Coalition (NOC) are encouraging their members to contact President Obama and the U.S. Department of Agriculture (USDA) and tell them not to approve (or not deregulate) Monsanto’s “RoundUp Ready,” genetically engineered (GE) alfalfa, which contributes to genetic drift, superweeds, and the use of a hazardous herbicide glyphosate. In December, USDA completed its environmental impact statement (EIS) of GE alfalfa. Secretary of Agriculture Tom Vilsack has rejected the option to prohibit the planting (and continuing to regulate) GE Alfalfa, despite the clear recognition in the EIS that that GE contamination of organic and conventionally grown crops presents a huge problem. USDA released its 2,400 page EIS as required by a 2007 Federal District Court decision and upheld by both 2009 Ninth Circuit Court of Appeals and June 2010 U.S. Supreme Court rulings. The litigation was led by the Center for Food Safety, and joined by Beyond Pesticides, and other groups, including conventional and organic seed companies and producers. Three alternatives are considered during the preparation of the final EIS: 1) to maintain the RR alfalfa’s status as a regulated article; 2) to deregulate RR alfalfa; or 3) to deregulate RR […]

(Beyond Pesticides, January, 11, 2011) Responding to a June 2006 petition submitted by Fluoride Action Network, Beyond Pesticides, and Environmental Working Group, the U.S. Environmental Protection Agency (EPA) has announced that it proposes to eliminate the use of the toxic fumigant sulfuryl fluoride in agriculture and food related applications. The agency plans to cancel all allowable pesticide residue levels (tolerances) for the chemical, finding that, when residues on food products are combined with fluoridated drinking water and toothpaste, public exposure levels are too high. Under the Federal Food, Drug, and Cosmetic Act (FFDCA), EPA is required to ensure that pesticides it has registered for use cannot combine with non-food sources of the same substance to result in unsafe levels of exposure for that chemical. According to EPA officials, the decision appears to be the first time the agency has granted substantive formal objections to a pesticide tolerance rule based on public health advocates’ evidence that a particular chemical’s use violates the safety standard for aggregate exposures under federal law. Despite granting the petition’s assertion that total public exposure to fluoride is too high, EPA has denied the petition’s request for an immediate stay of all registered uses of sulfuryl fluoride.
