(Beyond Pesticides, July 19, 2010) The Washington D.C. based Center for Food Safety (CFS) has unveiled an application for mobile phones to help shoppers quickly and easily identify foods made with ingredients from genetically modified (GM) organisms. Many consumers are leery of GM foods, yet unfortunately producers are not required to label products that contain GM ingredients, leaving consumers guessing about what they are eating. To aid consumers where regulatory oversight has failed, CFS created its new True Food Shoppers Guide Mobile Application available for free through iTunes and Android Market. GM foods were first introduced into the U.S. food supply in 1994, promising to put an end to world hunger. Using genetic engineering, scientists were expected to create drought and salt tolerant crops, with higher yields and nutrient content. These crops never materialized, however, and industry giants such as Monsanto have collected huge revenues selling insecticide producing and herbicide resistant crops to American farmers. These crops have not only failed in their promise to boost crop yields, but studies have shown that they increase the use of pesticides, and create herbicide resistant weeds. While disillusionment with GM crops grows, the US government continues to bow to industry lobbyists, refusing […]

(Beyond Pesticides, July 16, 2010) Under pressure from the grassroots group Alaska Community Action on Toxics (ACAT), the city of Anchorage canceled plans to spray the herbicides 2,4-D and dicamba on the Town Square Park citing concerns over the safety of children playing in the park. ACAT members attended the Anchorage Assembly public meeting with an NBC TV affiliate and discussed their reservations over spraying Town Square Park, a popular gathering place for families, workers eating their lunches, and tourists. Soon after, the mayor announced the spraying would be canceled, and that the city would remove dandelions by hand. Environmentalists called the decision a victory for the health of Anchorage residents and the environment. 2,4-D is associated with a host of adverse human impacts, such as non-Hodgkin’s lymphoma, endocrine disruption, reproductive and developmental effects, as well as water contamination and toxicity to aquatic organisms. It is one of the most widely used herbicide for the control of broadleaf weeds in commercial agriculture and residential landscapes in the U.S. About 46 million pounds of 2,4-D are used annually, with 16 million pounds used in non-agricultural settings, including parks, playing fields, and residential lawns. Its health risks prompted a Special Review in […]

(Beyond Pesticides, July 15, 2010) Swiss chemical manufacturing giant Syngenta, one of the makers of the commonly used and heavily scrutinized pesticides atrazine, are speaking out against anti-pesticide activists and the U.S. Environmental Protection Agency’s (EPA) review of atrazine. Despite mounting peer-reviewed scientific literature and research, Syngenta refuses to acknowledge the dangers of atrazine and, according to Legal Newsline, claims that the review is “redundant,” and merely “an unprecedented war on agriculture by anti-pesticide activists.” The company, which made over $11 billion in sales in 2009 even accuses the Natural Resources Defense Council (NRDC), which has spearheaded a campaign to persuade EPA to initiate reviews, of being “slick” and “well-funded.” Other critics of the agency’s decision include the American Council on Science and Health (ACSH), a group that has in the past received funding from Monsanto and Union Carbide (according to the group Center for Science in the Public Interest, ACSH stopped disclosing corporate donors in the early 1990’s). Dr. Gilbert Ross, medical director of ACSH told Legal Newswire that they believe EPA Administrator Lisa P. Jackson to be “cooperating with, if not spearheading, a broad-based activist agenda.” An article by The Huffington Post Investigative Fund published last week, however, […]

(Beyond Pesticides, July 14, 2010) The U.S. Environmental Protection Agency (EPA) announced that Monsanto Company Inc. has agreed to pay a $2.5 million penalty to resolve misbranding violations related to the sale and distribution of cotton seed products containing genetically engineered (GE) pesticides. This is the largest civil administrative penalty settlement ever received under the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). “This agreement shows that when a company violates the law by distributing misbranded pesticides, EPA will take action,” said Cynthia Giles, assistant administrator for EPA’s Office of Enforcement and Compliance Assurance. “The regulated community should understand that we take these violations seriously, and the public will accept nothing less than compliance.” “People who manufacture and distribute pesticide products must follow the federal registration requirements,” said Steve Owens, assistant administrator for EPA’s Office of Chemical Safety and Pollution Prevention. “These requirements are critical to preventing the development and spread of insect resistance.” Monsanto Bollgard and Bollgard II cotton seed products contain genetically engineered pesticides known as plant incorporated protectants (PIPs), which are registered as a pesticidal product under FIFRA. As a condition of the registrations, EPA included planting restrictions on Bollgard and Bollgard II, which contain the PIP Bacillus […]

(Beyond Pesticides, July 13, 2010) Beyond Pesticides is urging the public to send comments by July 19, 2010 to the Environmental Protection Agency (EPA) on its recently issued draft “general permit” under the Clean Water Act (CWA) that will govern aquatic pesticides and certain pesticide spraying over or near surface waters, including mosquito spraying and spraying over forest canopies and near irrigation ditches. Environmental groups believe the pesticide industry is lobbying to make this permit as weak as possible. Beyond Pesticides encourages individuals to send comments to EPA supporting strong, meaningful regulation of pesticide applications in order to fully protect public health and the environment. See talking points and instructions for sending comments below. Background EPA announced the public availability of a draft National Pollutant Discharge Elimination System (NPDES) General Permit, posted here, for certain pesticide use patterns, also known as the Pesticides General Permit (PGP) on June 2, 2010. The action stems from a 2009 court decision in the case of the National Cotton Council et al. v. EPA, in which the 6th circuit court of appeals ruled that pesticide discharges into water are pollutants and require permitting under the CWA. This ruling overturned the Bush administration policy that […]

(Beyond Pesticides, July 12, 2010) A study comparing the quality (measured in fat and protein content, egg white and shell thickness, and other physical characteristics) of various types of chicken eggs, including conventional, free-range and organic, failed to examine pesticide residues or vitamin content, nor does it consider the environmental and health impacts of conventional, chemical-based production systems, according to food and environmental safety advocates. The study is receiving attention after a recent article in Time magazine points out that organic eggs are often three times more expensive than conventional factory farm eggs. The study concludes that there is no substantial quality difference between eggs produced under different production systems. The study, “Physical quality and composition of retail shell eggs,” which was originally published in the March 2010 issue of the journal Poultry Science, compares white and brown large-shell eggs with various production and nutritional differences such as traditional, cage-free, free-roaming, pasteurized, nutritionally-enhanced (omega-3 fatty acids), fertile and organic. The study examined two dozen eggs of each variety taken from two Athens, GA grocery stores on three separate occasions. ARS food technologist Deana Jones and her team in the agency’s Egg Safety and Quality Research Unit, found that on average, […]

(Beyond Pesticides, July 9, 2010) Researchers at Swansea University in the UK have discovered a naturally occurring fungus as an alternative to pesticides for a wide range of crops. The fungal biological control agent, Metarhizium anisopliae, performed very well against the larvae of western flower thrips and vine weevils when applied as a spray or premixed into the growing medium. The researchers were able to achieve almost total control of the pest by combining the Metarhizium with nematodes, making it a huge environmental success. Professor Tariq Butt, who led the ongoing research at Swansea observed, “The benefits are far reaching””not just for those with organic farms or nurseries but also for conventional growers, offering an effective, environmentally friendly alternative to chemicals.” Professor Butt, from the University’s School of Environment and Society, believes this new development could help reduce the use of pesticides and their impact on the environment while reducing costs for farmers. The project was funded by the Department for Environment, Food and Rural Affairs under the UK Horticulture LINK program, the government’s main vehicle for sponsoring applied research in horticulture. You can read the official university press release here. The fungus has been registered in Europe with Novozymes, […]

(Beyond Pesticides, July 8, 2010) Just over a year after the Ontario ban on cosmetic pesticides, an Ontario study found an over 80% decline of the most commonly used lawn pesticides in urban stream and creeks. Staff of the Ministry of Environment and Conservation Authorities conducted a water quality monitoring study of 10 urban streams and creeks in Ontario. The study was conducted pre/post cosmetic pesticide ban in Ontario, during the summer of 2008 and 2009. The report looks at 168 stream water samples that were taken over 2008 and 2009, which compares the water quality before and after the ban took effect. Sampling points were selected in areas mainly influenced by residential run-off — away from golf courses, sewage treatment plant effluents, and agricultural applications. The samples were analyzed for 105 pesticides and pesticide degradation products. Preliminary results show a significant drop in concentrations of three commonly used lawn care products: 86 % of 2,4-D, 82% of dicamba, and 78% of MCPP. Previous estimates indicate that these three herbicides accounted for over half the total amount of pesticides used by lawn care companies in Ontario. On the other hand, concentrations of some pesticides did not significantly change. Other pesticides […]

(Beyond Pesticides, July 7, 2010) Long-term exposure to nitrates, a common agricultural water contaminant, through food and water may increase an older woman’s risk of thyroid disease, a recent study in Iowa finds. Public water supplies contaminated with nitrates increased the risk of thyroid cancer in the women. Eating nitrates from certain vegetables was also linked to increases in thyroid cancer and hypothyroidism, one type of thyroid disease. Nitrate is a common contaminant of drinking water, particularly in agricultural areas where nitrogen fertilizers are used. High rates of fertilizer application may also increase the natural nitrate levels found in certain vegetables, such as lettuce and root crops. In the body, nitrate competes with uptake of iodide by the thyroid, thus potentially affecting thyroid function. This is the first study to show a link between nitrates and thyroid cancer in people, although nitrates have been shown to cause thyroid tumors in animal studies. Researchers at the National Institute of Health, in a study entitled, ”Nitrate intake and the risk of thyroid cancer and thyroid disease,” investigated the association of nitrate intake from public water supplies and diet with the risk of thyroid cancer and self-reported hypothyroidism and hyperthyroidism in a cohort […]

(Beyond Pesticides, July 6, 2010) A review report published last Friday highlights that some research studies indicate that pesticide exposure either prior to conception, during pregnancy or during childhood appears to increase the risk of childhood cancer, with maternal pesticide exposure during pregnancy being most consistently associated with childhood cancer. Furthermore, the report notes that several studies indicate that farmers are at greater risk of developing certain cancers than the general population. In particular, several studies strongly suggest that pesticide exposures are associated with some cases of non-Hodgkin’s lymphoma (NHL), leukemia, prostate cancer and other hormone related cancers. The report, A Review of the Role Pesticides Play in Some Cancers: Children, farmers and pesticide users at risk?, is published by the United Kingdom organization CHEM (Chemicals, Health and Environment Monitoring) Trust. “Pesticide exposures may interact with other chemical exposures and genetic factors, to cause cancer. Research suggests that pregnant women, in particular, should avoid direct exposure to pesticides, if possible,” said Gwynne Lyons, Director of CHEM Trust and report co-author. “It is high time that the UK was more supportive of EU proposals to take a tougher approach to reducing exposure to potentially harmful chemicals. If the UK is to […]

(Beyond Pesticides, July 2, 2010) A study by researchers from Washington State University (WSU) and the University of Georgia suggests that a balanced mix of insects and fungi in organic fields provides for both better pest control and larger plants than in conventional agriculture. The study, which was funded by the U.S. Department of Agriculture’s (USDA) National Institute of Food and Agriculture (NIFA) and published in the July 1 edition of the journal Nature, shows that organic farming practices lead to many equally-common beneficial species, and that this reduces pest problems. “It’s always been a mystery how organic farmers get high yields without using synthetic insecticides,” says co-author Bill Snyder, Ph.D., associate professor of entomology at WSU. “Our study suggests that biodiversity conservation may be a key to their success.” The study involved 42 potato plots enclosed in fine mesh on the Pullman campus of WSU. The researchers planted both potato plants and Colorado potato beetles (a very problematic pest of the potato) in each of the plots, adding varying numbers of beneficial insects, fungi and nematodes, microscopic soil-dwelling worms that attack beetles’ eggs and larvae. Crops placed in the organic test plots with a more balanced insect population grew […]

(Beyond Pesticides, July 1, 2010) A recent study by Seong Park, Ph.D., published in the Agronomy Journal, demonstrates that manure generates higher economic returns than anhydrous ammonia, a synthetic fertilizer. Dr. Park, a research economist with Texas AgriLife Extension Service found no significant difference in yield between organic and chemical nutrient sources. The long-term experiment conducted in the Oklahoma Panhandle compares the use of pig and beef manure to anhydrous ammonia in irrigated corn fields. The region has seen rapid growth of animal population and density. The use of animal manure for fertilizer not only reduces or eliminates the need for synthetic fertilizers, it also significantly reduces waste management costs. Dr. Park found anhydrous ammonia to be the most costly source of nitrogen, due to purchase price, which is not normally required when using beef or swine manure. Swine effluent had the lowest application costs since it can be applied through existing irrigation equipment. The only additional cost would be equipment to pump effluent from the lagoon where it is stored to the center pivot. Beef manure and anhydrous ammonia require application machinery. Beef manure is however a more economical choice if it is being transported to crops on another […]

(Beyond Pesticides, June 30, 2010) The U.S. Environmental Protection Agency (EPA) approval process for thousands of antimicrobial products is woefully inadequate, according Public Employees for Environmental Responsibility (PEER). Despite a growing body of scientific evidence about the side-effects of these products, EPA rubberstamps registrations without duly considering an array of potential public health and environmental impacts. Antimicrobials are now a billion dollar business with more than 5,000 such products currently registered with EPA. Initially designed for hospitals and clinics, antimicrobial pesticides are today found in products ranging from household cleaners to mattresses and bedding, cosmetics, toys, toothpaste and even chopsticks. Antibacterial products are being marketed to the health conscious without firm evidence of real benefits and amid growing concern about downstream consequences. One prime example of this is the antibacterial pesticide triclosan that is formulated into hundreds of personal care products, toys and textiles. Studies show that triclosan is an endocrine disruptor, accumulates in human fatty tissue and can influence the onset of bacterial resistance. Beyond Pesticides, Food and Water Watch and several other groups petitioned FDA in 2009 and EPA in January 2010, calling for the ban of triclosan citing the possibility of bacterial resistance to antibacterial substances and […]

(Beyond Pesticides, June 29, 2010) Based on a flawed assessment, the authors of recent study out of the University of Guelph in Ontario, Canada have been attacking organic agriculture as less environmentally friendly than chemical-intensive conventional methods. In their press release, the authors say, “Consumers shouldn’t assume that because a product is organic it’s also environmentally friendly.” However after analyzing the study, Beyond Pesticides determined that this message is flawed and misleads consumers because the study does not actually evaluate an organic system. Instead the study substitutes natural pesticides that are approved in organic systems for synthetic pesticides in a conventional soybean field. The authors warned policy makers against promoting organic agriculture, based on the false assumptions of their study. “If the goal of their study was to educate consumers as their message to the media suggests, then the authors of this study have shown a surprising lack of knowledge about organic agriculture,” said Beyond Pesticides project director John Kepner. “Organic agriculture is based on pest prevention and soil health. Organic farmers use techniques such as crop rotation and the creation of habitat for beneficial species, with organic-approved natural pesticides only as a last resort. Substituting these chemicals into a […]

(Beyond Pesticides, June 28, 2010) A new report documents high levels of pesticide drift in the California community of Sisquoc. Poison Gases in the Field: Pesticides put California families in danger, released by Pesticide Action Network North America and local community members, presents results of community air monitoring for fumigant pesticides in the central coast area of California, in Santa Barbara County. Using a simple monitoring device called the Drift Catcher, community members measured levels of a fumigant pesticide above the California Department of Pesticide Regulation’s (DPR) “level of concern” — even when all application rules were followed and no equipment failure occurred. “While we were monitoring the air, there were no violations of the County’s permit – and yet we found we were still breathing chloropicrin at high levels,” says Deby DeWeese, one of the community members who collected air samples. “Clearly the rules and regulations do not protect our families.” The Sisquoc monitoring, conducted during and after a soil fumigation in April 2008, found the pesticide chloropicrin in about half of the 57 air samples collected. Two samples had chloropicrin levels higher than DPR’s 24-hour level of concern for children, and the 19-day average level at one sampling […]

(Beyond Pesticides, June 25, 2010) Two new studies published in the journal Environmental Science and Technology confirm that the majority of toxic contamination threatening national parks originates from agricultural pesticides and industrial operations. In one study an international group of scientists conducted research from 2003-2005 and detected elevated concentrations of various dangerous pesticides in all eight of the national parks and preserves. The other study collected samples of air, water, snow, sediment, lichens, conifer needles, and fish at remote alpine, subarctic, and arctic sites. Researchers found that these samples contained four current-use pesticides including dacthal (DCPA), chlorpyrifos, endosulfans, and y-hexachlorocyclohexane (HGH) as well as four historic-use pesticides including dieldrin, a-HCH, chlordanes, and hexachlorobenzene (HCB). Pesticide concentrations in snow are highest in Sequoia, Kings Canyon, Rocky Mountain and Glacier National Parks. Concentrations in vegetation are mostly dominated by endosulfan and dacthal, and are highest in Yosemite, Kings Canyon, Glacier, and Great Sand Dunes National Park and Preserve. Fish samples also show elevated concentrations of dieldrin and DDT (one of the first pesticides to be banned in 1972 because of Rachel Carson’s Silent Spring). Cold temperatures in alpine or arctic ecosystems tend to concentrate pesticides, which can also bioaccumulate in the local […]

(Beyond Pesticides, June 24, 2010) Our food purchases have a direct effect on the health of our environment and those who grow and harvest what we eat. Beyond Pesticides launched its Organic Food: Eating with a Conscience guide, which shows consumers why, according to the group, “food labeled organic is the right choice.” Jay Feldman, executive director of Beyond Pesticides, said, “In addition to serious health questions linked to actual residues of toxic pesticides on the food we eat, our food buying decisions support or reject hazardous agricultural practices, protection of farmworkers, and stewardship of the earth.” The Eating with a Conscience guide explains to consumers the effect they are having on health and the environment when they purchase food grown with chemical-intensive methods, even if a large number of residues do not remain on the finished food product. The group points to USDA organic certification as “the only system of food labeling that is subject to independent public review and oversight, assuring consumers that toxic, synthetic pesticides used in conventional agriculture are replaced by management practices focused on soil biology, biodiversity, and plant health.” “Organic practices under the Organic Foods Production Act eliminate commonly used toxic chemicals in the […]

(Beyond Pesticides, June 23, 2010) The Supreme Court ruling in Monsanto v Geersten Seed Farms on June 21, 2010 appears to favor the St. Louis-based biotech giant, but may offer some protection from genetically engineered (GE) crops. In a 7 to 1 decision, the high court overturned a lower court injunction on the planting of GE alfalfa, yet planting the crop still remains illegal until USDA completes assessing its environmental review. Interestingly, Justice Steven G. Breyer recused himself because his brother District Judge Charles Breyer had issued the original ruling, while Justice Clarence Thomas did not recuse himself despite having worked as a Monsanto attorney for two years. In 2006, the Center for Food Safety (CFS) and several other farming and environmental groups, including Beyond Pesticides, filed suit on behalf of Geerston Seed Farms. The suit led to a U.S. District Court ruling that the U.S. Department of Agriculture (USDA) violated the National Environmental Protection Act (NEPA) by approving the sale of GE alfalfa without requiring an environmental impact statement (EIS). Monstanto was forced to stop selling the seed until a comprehensive EIS is prepared and assessed. A draft EIS was prepared in 2009. This was the first ever moratorium […]

(Beyond Pesticides, June 22, 2010) The U.S. Environmental Protection Agency (EPA) announced earlier this month that it is seeking public comment on its draft five-year strategic plan, which the agency says will help advance Administrator Lisa P. Jackson’s priorities and EPA’s overall mission to protect human health and the environment. Administrator Jackson’s seven priorities are; taking action on climate change, improving air quality, protecting Americas waters, cleaning up our communities, assuring the safety of chemicals, expanding the conversation on environmentalism and working for environmental justice, and building strong state and tribal partnerships. In accordance with the Government Performance and Results Act of 1993 (GPRA), EPA submitted the agency’s 2006-2011 Strategic Plan to Congress on September 29, 2006. Now, the agency is releasing its Draft FY 2011-2015 Strategic Plan for public review and comment through July 30, 2010. GPRA requires agencies to develop a five-year Strategic Plan for what they intend to accomplish, measure how well they are doing, make appropriate decisions based on the information they have gathered, and communicate information about their performance to Congress and to the public. It includes a mission statement and sets out long-term goals and objectives; Annual Performance Plans, which provide annual performance commitments […]

(Beyond Pesticides, June 21, 2010) Pesticide experiments using people as test subjects will have stricter federal rules to follow under a new agreement reached on June 17, 2010 between the U.S. Environmental Protection Agency (EPA) and public health groups, farm worker advocates and environmental organizations. “People should never have been used as lab rats for testing pesticides,” said Natural Resources Defense Council (NRDC) senior attorney Michael Wall. “Under today’s settlement, EPA will propose far stronger safeguards to prevent unethical and unscientific pesticide research on humans.” In 2006, a coalition of health and environmental advocates and farmworker protection groups led by NRDC filed a lawsuit against EPA, claiming EPA’s recent rule violated a law Congress passed in 2005 requiring strict ethical and scientific protections for pesticide testing on humans. EPA’s 2006 rule lifted a ban on human testing put in place by Congress. It also allows experiments in which people are intentionally dosed with pesticides to assess the chemicals’ toxicity and allows EPA to use such experiment to set allowable exposure standards. In such experiments, people have been paid to eat or drink pesticides, to enter pesticide vapor “chambers,” and to have pesticides sprayed into their eyes or rubbed onto their […]

(Beyond Pesticides, June 18, 2010) A panel of U.S. and Vietnamese policy makers, scientists, and citizens released a report on Wednesday urging the U.S. government and other donors to provide $300 million to clean up contaminated sites and care for Vietnamese harmed by exposure to Agent Orange, an herbicide used by the U.S. to defoliate large swaths of forest during the Vietnam War that was contaminated by dioxin. Dioxin is a very persistent toxicant that clings to the soil and sediments, and bioaccumulates in the food chain. Many studies have linked dioxin exposure to a myriad of health effects including cancer, neuropathy, diabetes, Parkinson’s Disease, and birth defects. This report comes one month before the U.S. and Vietnam will celebrate 15 years of normalized diplomatic relations. The U.S.-Vietnam Dialogue Group on Agent Orange/Dioxin released the report calling for an estimated $30 million annually for the next 10 years. Since 2007, the U.S. has spent only $9 million on dioxin remediation and assisting disabled Vietnamese. The report lays out a plan with three phases. The first phase, lasting three years and estimated to cost $100 million, would focus on completing remediation in Da Nang, one of the largest contaminated sites. This […]

(Beyond Pesticides, June 17, 2010) Researchers have found detectable levels of common household pesticides in the majority of umbilical cord blood of babies born at an urban hospital. The study looks at concentrations of organophosphate (OP), carbamate, pyrethroids, and organochlorine pesticides in samples of umbilical cord blood taken from newborns delivered at the Johns Hopkins Hospital Labor and Delivery Suite in Baltimore. Researchers looked at the umbilical cord serum, as opposed to maternal serum, in order to provide a more direct estimate of exposure to the fetus. While human biomonitoring studies have found detectable levels of these pesticide chemicals in urine and blood samples from children and adults in the past, few studies have been carried out in the U.S. evaluating exposure in utero. In addition to tracking pesticide concentrations, researchers also aimed to identify demographic and socioeconomics factors associated with in utero pesticide exposure. Anonymous anthropometric and sociodemographic characteristics of the mothers and infants were collected along with umbilical cord blood that would have otherwise been discarded. Included in the characteristics collected that researchers considered might affect pesticide exposure risk were: age, race, body mass index, parity, education, health insurance, marital status, smoking, area of residence and housing density.

(Beyond Pesticides, June 16, 2010) Men with certain genetic variations who were exposed to some toxic pesticides that are now largely banned run an increased risk of developing Parkinson’s disease, French scientists said Monday. In a study published in Archives of Neurology, entitled “Interaction Between ABCB1 and Professional Exposure to Organochlorine Insecticides in Parkinson Disease,” French researchers found that among men exposed to pesticides such as DDT, carriers of the gene variants are three and a half times more likely to develop Parkinson’s than those with the more common version of the gene. The scientists think the brains of people with the gene variant fail to flush out toxic chemicals as efficiently as those with common versions of the gene, suggesting that environmental as well as genetic factors are important in the risk of Parkinson’s. Alexis Elbaz, MD, PhD and Fabien Dutheil, PhD, of France’s National Institute for Health and Medical Research (INSERM) studied 101 men with Parkinson’s and 234 without the disease to look at links between organochlorine exposure and Parkinson’s disease. The study includes only men, and all of them had high levels of exposure to pesticides through their work as farmers. The scientists found the link was […]
