(Beyond Pesticides, June 22, 2009) In April 2009, the U.S. Environmental Protection Agency (EPA) announced that it is intensifying its evaluation of spot-on pesticide products for flea and tick control for pets due to recent increases in the number of reported incidents. Adverse reactions reported range from mild effects such as skin irritation to more serious effects such as seizures and, in some cases, the death of pets. Incidents with flea and tick products can involve the use of spot-on treatments, sprays, collars and shampoos. However, the majority of the incidents reported to EPA are related to flea and tick treatments with EPA-registered spot-on products. Spot-on products are generally sold in tubes or vials and are applied to one or more localized areas on the body of the pet, such as in between the shoulders or in a stripe along the back. This advisory pertains only to EPA-registered spot-on flea and tick products; these products have an EPA registration number on the label. EPA now is evaluating all available data on the pesticides, including reports of adverse reactions, clarity of product use directions and label warnings, product ingredients, market share, and pre-market safety data submitted to the Agency. EPA says […]

(Beyond Pesticides, June 19, 2009) Farmworker unions, support groups, and worker advocacy organizations today asked Environmental Protection Agency (EPA) Administrator Lisa P. Jackson to stop the pesticide poisoning of farmworker communities and uphold the Obama administration’s commitment to environmental justice. Citing a long EPA history of “inhumane neglect of toxic pesticide effects on farmworker community health,” the groups asked the Administrator to amend a recent May 2009 decision that allows the continued use of hazardous soil fumigant pesticides. The chemicals when used in chemically treated crop production, such as tomatoes, carrots, strawberries and nuts, escape into the environment and drift into communities where the families and children of farmworkers live and play. The letter, signed by 28 groups from across the country, says that the new fumigants policy “continues an outdated EPA approach to pesticide regulation that adopts unrealistic and unenforceable standards as risk mitigation measures, in an age of safer, greener approaches to agricultural pest management.” EPA announced its decision May 27, 2009 to allow continued use of toxic soil fumigants with modified safety measures, falling far short of safety advocate efforts to adopt more stringent use restrictions and chemical bans. The rule was first proposed in July 2008, […]

(Beyond Pesticides, June 16, 2009) A study involving 678 individuals who apply pesticides, culled from a U.S. Agricultural Health Study of over 50,000 farmers, recently found that exposure to certain pesticides doubles one’s risk of developing an abnormal blood condition called MGUS (monoclonal gammopathy of undetermined significance) compared with individuals in the general population. The disorder, characterized by an abnormal level of a plasma protein, requires lifelong monitoring as it is a pre-cancerous condition that can lead to multiple myeloma, a painful cancer of the plasma cells in the bone marrow. The study will appear in the June 18 issue of Blood, the official journal of the American Society of Hematology. “Our study is the first to show an association between pesticide exposure and an excess prevalence of MGUS,” said lead author Ola Landgren, M.D., Ph.D., of the National Cancer Institute (NCI), which is part of the National Institutes of Health, U.S. Department of Health and Human Services. “This finding is particularly important given that we recently found in a large prospective cancer screening study that virtually all multiple myeloma patients experienced a MGUS state prior to developing myeloma.” “As several million Americans use pesticides, it’s important that the risks […]

(Beyond Pesticides, June 8, 2009) A new epidemiological study finds that Parkinson’s disease patients who have been exposed to pesticides through their work show elevated rates of the disease. The researchers find that French farmworkers have nearly double the risk for the disease if exposed to pesticides, with a dose-effect for the number of years of exposure. When they looked at the three major classes of pesticides (insecticides, fungicides and herbicides), they find that the farmworkers who used insecticides had over a two-fold increase in the risk of Parkinson’s disease. A slightly higher risk is found for exposure to organochlorine insecticides. According to the study, these associations are stronger in men with older onset Parkinson’s disease than in those with younger onset Parkinson’s. The study, “Professional Exposure to Pesticides and Parkinson’s Disease,” published in Annals of Neurology, involved individuals affiliated with the French health insurance organization for agricultural workers who were frequently exposed to pesticides in the course of their work. Occupational health physicians constructed a detailed lifetime exposure history to pesticides by interviewing participants, visiting farms, and collecting a large amount of data on pesticide exposure. These included farm size, type of crops, animal breeding, which pesticides were used, […]

(Beyond Pesticides, June 2, 2009) U.S. Representative Henry Waxman (D-CA), chairman of the House Energy and Commerce Committee, along with Chair Emeritus John D. Dingell (D-MI), and Reps. Frank Pallone (D-NY), Bart Stupak (D-MI), Diana DeGette (D-CO) and Betty Sutton (D-OH), released a “discussion draft” of the Food Safety Enhancement Act of 2009, which they say will improve food safety by making the food supply more transparent, inspections of food facilities more frequent and requiring manufacturers to take steps to prevent food-borne illnesses. Sustainable agriculture advocates warn that a one-size-fits-all approach would require expensive investments beyond the reach of most small farms and processors, and could potentially put some out of business. The Committee has scheduled a legislative hearing for June 3, 2009. The draft language is largely based on the food provisions of H.R. 759, the Food and Drug Administration Globalization Act of 2009, introduced in January by Reps. Dingell, Stupak, and Pallone. The Food Safety Enhancement Act of 2009 incorporates technical assistance from the Obama Administration as well as other stakeholders. According to Rep. Waxman, the legislation grants the Food and Drug Administration (FDA) the authorities and resources it needs to better ensure the safety of the nation’s […]

(Beyond Pesticides, June 1, 2009) Many believe that nature’s best weed control is goats and that is why the Maryland Department of Transportation, town of Heampstead, New York, Google Corporate office campus in Mountain View, California, Mesa, Arizona Utilities Department and City of Cheyenne, Wyoming are putting goats to work this spring. Whether its 5 or 700 goats managing weeds, brush and grasses along highways, on a nature preserve, on a corporate campus or on a water reclamation plant property, goats are doing the work in an environmentally-friendly way. Goats eat unwanted plants, add fertilizer to the area and aerate the soil with their hooves, all at the same time. They show up every day to work, never complain, and they are tireless in performing their job. Maryland Department of Transportation The Maryland Department of Transportation’s State Highway Administration (SHA) had a major dilemma — how to mow the turf amid the meadows and bogs that protect the threatened Bog Turtle around a major highway bypass in the state. The best solution — use goats as lawn mowers. In late May, SHA enlisted a herd of 40 goats from a local farmer to begin a conservation grazing project on approximately […]

(Beyond Pesticides, May 28, 2009) Two commonly used herbicides, pendimethalin and EPTC, show a statistically significant exposure-response association with pancreatic cancer. The new study, “Agricultural Pesticide Use And Pancreatic Cancer Risk In The Agricultural Health Study Cohort,” published earlier this month in the International Journal of Cancer, is a case-control study of pesticide applicators and their spouses in Iowa and North Carolina. After controlling for age, smoking and diabetes, the study finds a three-fold increased risk with lifetime pendimethalin use and a two-and-a-half-fold increased risk with lifetime use of EPTC when compared to those that never used the chemicals. Among the 24 pesticides examined, having ever used one of five pesticides (trifluralin, chlorimuron-ethyl, pendimethalin, EPTC or heptachlor) shows at least a 40 percent excess risk of pancreatic cancer. According to the U.S. EPA’s pesticide sales and usage statistics, pendimethalin is the third most commonly used home and garden (and other non-agricultural use) herbicide and the 7th most commonly used herbicide in agriculture, totaling 21-30 million pounds applied annually in the U.S. Pendimethalin is listed by the U.S. EPA as a Group C – Possible Human Carcinogen and is a suspected endocrine disruptor. Pendimethalin has been found to cause central nervous […]

(Beyond Pesticides, May 26, 2009) On May 19, 2009, the American Academy of Environmental Medicine (AAEM) released a position paper on genetically engineered (GE) foods stating that, “Genetically engineered foods pose a serious health risk,” and calling for a moratorium on GE foods. Citing several animal studies, the AAEM concludes “there is more than a casual association between genetically engineered foods and adverse health effects” and that “GE foods pose a serious health risk in the areas of toxicology, allergy and immune function, reproductive health, and metabolic, physiologic and genetic health.” The AAEM’s position paper on genetically engineered foods can be found on its website. “Multiple animal studies have shown that GE foods cause damage to various organ systems in the body,” said Amy Dean, M.D., public relations chair and board member of AAEM. “With this mounting evidence, it is imperative to have a moratorium on GE foods for the safety of our patients’ and the public’s health.” The AAEM calls for: — A moratorium on GE food, implementation of immediate long term safety testing and labeling of GE food. — Physicians to educate their patients, the medical community and the public to avoid GE foods. — Physicians to consider […]

(Beyond Pesticides, May 22, 2009) A balanced, organic diet – both before and during pregnancy – can significantly reduce a child’s likelihood of being overweight, obese or developing diabetes. That, according to a literature review of over 150 scientific studies assembled by The Organic Center (TOC), an organic industry research institute focused on the science of organic food and farming. The TOC review”That First Step: Organic Food and a Healthier Future” documents that exposure to pesticides during pregnancy increases the risk of premature birth, low-birth weight, neurological problems and diabetes. Outlining six ways in which a balanced organic diet can contribute to healthy development, the report also examines how enzymes found in organic foods can slow and even reverse aspects of the aging process. With the time between initial conception to the early years of development being the most critical in establishing lifelong health, a well-balanced diet rich in organic fruits and vegetables helps establish healthy food-taste preferences, promotes healthy patterns of cell division and largely eliminates exposures to approximately 180 pesticides known to increase the risk of developmental abnormalities. Furthermore, this combination of reducing pesticide exposure and consuming nutrient-dense organic foods can help people manage weight and prevent diabetes. […]

(Beyond Pesticides, May 8, 2009) The United Nations Environment Programme (UNEP) and the World Health Organization (WHO), in partnership with the Global Environment Facility, have announced a renewed international effort to combat malaria with an incremental reduction of reliance on the synthetic pesticide DDT. As recently as two years ago, WHO was criticized for promoting DDT as the answer for malaria control in Africa, leading activists to call for increased use of alternatives. DDT has been recognized as a significant human and environmental health risk, including increased risk of breast cancer a wealth of other health concerns, and have built up in waterways and, in particular, the arctic. Now, ten projects, all part of the global program “Demonstrating and Scaling-up of sustainable Alternatives to DDT in Vector Management,” involving some 40 countries in Africa, the Eastern Mediterranean and Central Asia, are set to test non-chemical methods ranging from eliminating potential mosquito breeding sites and securing homes with mesh screens to deploying mosquito-repellent trees and fish that eat mosquito larvae. The new projects follow a successful demonstration of alternatives to DDT in Mexico and Central America. There, pesticide-free techniques and management regimes have helped cut cases of malaria by over 60 […]

(Beyond Pesticides, May 4, 2009) Targeting areas frequented by children, such as playgrounds, picnic areas, baseball fields, campgrounds, beaches, and hiking trails, New York Governor David A. Paterson announced an initiative to substantially reduce pesticide use throughout the State park system. “New York has a magnificent State park system that is a tremendous resource for all New Yorkers,” said Governor Paterson. “People visiting our parks, particularly children, should not be exposed to pesticides. This effort will reduce or, when possible, eliminate the use of pesticides in our State parks and historic sites.” The pesticide reduction policy is an outgrowth of Governor Paterson’s Executive Order No. 4, adopted in April 2008, which established procurement specifications to minimize State pesticide use by State agencies. The State Parks policy goes further than the Executive Order requirements by eliminating pesticide use to the maximum extent possible. The goal is to keep parks pesticide-free. The approach is outlined in the Office of Parks, Recreation and Historic Preservation’s Sustainability Plan, an agency-wide strategy to improve energy conservation, improve the sustainability of parks and historic sites, improve waste reduction and recycling efforts, enhance green procurement, and incorporate sustainability in education, training and interpretation efforts. “Now that the […]

(Beyond Pesticides, April 29, 2009) The U.S. Environmental Protection Agency (EPA) announced earlier this month that it is finally ready to move forward with preliminary testing of 67 active and inert pesticide ingredients for possible endocrine disrupting effects. But, according to prominent researcher and author Theo Colborn, PhD, these tests are outdated, insensitive, crude, and narrowly limited, and will fail to detect many serious effects on human development. In an eye-opening opinion-editorial published in Environmental Health News, Dr. Colborn, founder and president of The Endocrine Disruption Exchange, and Co-author of Stolen Future, says that EPA’s testing protocol is “a pitiful skeleton” of what it needs to be. The tests to be used by EPA were first recommended in 1998. Since then the science has made progress and become more sophisticated. Current research is based on different assumptions than the toxicological assumptions that first drove the EPA test designs. However, EPA has not updated its protocol. Each of EPA’s tests and assays was designed under the surveillance of corporate lawyers who had bottom lines to protect and assorted toxicologists who were not trained in endocrinology and developmental biology. For over a decade, EPA ignored the vast wealth of information on endocrine […]

(Beyond Pesticides, April 22, 2009) The California Department of Pesticide Regulation (DPR) released its “Top Pesticide Blunders” report to remind the public to avoid illness and injury by using household cleaning and gardening products that pose the least risk to their health and the environment. The blunders also include situations in which users of toxic products fail to comply with product labels. “Disinfectants, mold and mildew cleaners, weed killers and pool chemicals are just a few of the many over-the-counter pesticide products available for home use,” DPR Director Mary-Ann Warmerdam said. “As people begin their spring cleaning and gardening, they should select products that best target the problem and then follow the label instructions carefully to prevent accidents.” Beyond Pesticides adds that people should consider non-chemical approaches that manage unwanted insects and plants with prevention-oriented practices. Ms. Warmerdam suggests the following precautions to prevent pesticide exposure in and around the home: *Select products that pose the least risk to your health and the environment — do you really need a pesticide for the task? *Never put pesticides in food or drink containers. Keep pesticides in their original containers so they are not mistaken for food or drink. *Store pesticides properly […]

(Beyond Pesticides, April 17, 2009) Thirteen years after the Food Quality Protection Act (FQPA) ordered EPA to develop a screening process for endocrine disrupting chemicals, the Environmental Protection Agency (EPA) has released a final list of chemicals to be included in Tier 1 testing for endocrine disrupting effects of pesticides in use. While the list has been reduced from the 73 chemicals announced two years ago, trials will begin this summer to determine human risk from some of the chemicals to which we are most commonly exposed. “Endocrine disruptors can cause lifelong health problems, especially for children,” stated EPA Administrator Lisa Jackson. “Gathering this information will help us work with communities and industry to protect Americans from harmful exposure.” EPA’s recent announcement of these chemicals can be found on EPA’s Endocrine Disruptor Screening Program (EDSP) page. According to EPA, “The Agency deleted 6 chemicals from the draft list of 73 based upon recent information showing that the chemicals are no longer expected to be found in 3 exposure pathways.” To be included on the initial list, EPA established that chemicals need to be found in three of EPA’s four exposure pathways: food, drinking water, residential use, and occupational exposure. Azinphos-methyl […]

G(Beyond Pesticides, April 14, 2009) Groups are seeking an end to a failed U.S.-supported herbicide spray program that between 2000 and 2008 cost U.S. taxpayers more than half a billion dollars to apply the toxic herbicide glyphosate on approximately three million acres of land in Colombia””the world’s second most biodiverse country. The herbicide spraying, targeted at coca — the raw ingredient used to make cocaine, is toxic to people and wildlife, wreaks havoc on native ecosystems and has proven to be an ineffective tactic in the “War on Drugs.” Beyond Pesticides encourages you to join with EarthJustice and send a letter to the Obama Administration asking the government to stop supporting this destructive policy. Colombia is the only country in the world that allows this kind of herbicide spraying””known as fumigation””as an anti-drug practice. Yet the spraying has been a complete failure. According to U.S. government studies, the area subject to coca cultivation has actually increased by 23 percent since the U.S.-backed fumigation began in earnest, and Colombia remains the leading supplier of cocaine for U.S. markets. Coca farmers simply spread out and relocate the crops, moving deeper into the forest and clearing new areas. The environmental impacts have been […]

(Beyond Pesticides, April 1, 2009) A study published in the April 2009 issue of the medical journal Acta Paediatrica reports that the highest rates of birth defects for U.S. babies arise when conception occurs during the spring and summer months, when pesticide use increases and high concentrations of pesticides are found in surface waters. The study entitled, “Agrichemicals in surface water and birth defects in the United States” is the first study to link increased seasonal concentration of pesticides in surface water with the peak in birth defects in infants conceived in the same months. Researchers analyzed all 30.1 million births in the U.S. between 1996 and 2002. A strong association between higher rates of birth defects among women whose last menstrual period was in April, May, June or July and elevated levels of nitrates, atrazine and other pesticides in surface water during those same months was found. The correlation between the month of last menstrual period and higher rates of birth defects is statistically significant for half of the 22 categories of birth defects reported in the Centers for Disease Control database from 1996 to 2002, including spina bifida, cleft lip, clubfoot and Down’s syndrome. “Elevated concentrations of pesticides […]

(Beyond Pesticides, March 19, 2009) Researchers investigating the long-term immune effects of dioxin have found that exposure to dioxin during development or while nursing diminishes the capacity to fight infection later in life. The study, published in Toxicological Sciences, reported that mouse pups born to pregnant mice that were exposed to a small amount of dioxins had fewer white blood cells that normally kill the flu virus and more of a different kind that increases lung inflammation. The study entitled, “The aryl hydrocarbon receptor affects distinct tissue compartments during ontogeny of the immune system,” aimed to identify the critical windows of exposure where fetuses are most sensitive to dioxin’s harmful effects. Pregnant mice were given a dose of 1,000 ppt dioxin either during pregnancy, lactation, or throughout pregnancy and lactation. After dosing, mothers and pups were kept dioxin-free. Researchers then infected mothers and pups with a non-lethal dose of the influenza virus. Researchers found that the number of specialized white blood cells – referred to as CD8+ T-cells that specifically recognize and kill the flu virus, were significantly reduced in the pups but not their mothers. The most severe reduction in these white blood cells was seen when dioxin was […]

(Beyond Pesticides, March 16, 2009) Exposure to a mixture of the fungicide maneb and the herbicide paraquat significantly increases the risk of developing Parkinson’s disease, according to a new University of California, Berkeley study, “Parkinson’s Disease and Residential Exposure to Maneb and Paraquat from Agricultural Applications in the Central Valley of California.” Published in the American Journal of Epidemiology, the study findings show that exposure to both pesticides within 500 meters of an individual’s home increases the risk of developing Parkinson’s by 75 percent. For individuals 60 years of age or younger at the time of diagnosis, there is a more than four-fold increase in risk of the disease when exposed to a combination of maneb and paraquat and a more than doubling of risk when exposed to either maneb or paraquat alone. The Berkeley researchers used geographic information systems that analyzed data from California Pesticide Use Reports and land-use maps to calculate historical residential exposure to agricultural exposure to the two pesticides. From 1998 to 2007, the researchers enrolled 368 incident Parkinson’s disease cases and 341 population controls from California’s Central Valley and developed potential exposure estimates incurred between 1974 and 1999. Also published this month by some of […]

(Beyond Pesticides, March 2, 2009) Pesticide exposure and genetic variability in the dopamine transporter (DAT), a protein that plays a central role in dopaminergic neurotransmission of the brain, interact to significantly increase the risk factor for Parkinson’s disease, according to a new study by University of California, Los Angeles (UCLA) researchers. The population based case-control study, “Dopamine Transporter Genetic Variants and Pesticides in Parkinson’s Disease,” builds on the existing body of evidence of animal data and epidemiological studies that link exposure to pesticides, including gene-pesticide interactions, to Parkinson’s disease. The UCLA researchers, looking at incident Parkinson’s disease cases in three rural counties in Central California, find DAT increases the risk of Parkinson’s when individuals have occupational or residential exposure to pesticides. This is the first epidemiologic study of Parkinson’s disease that relies on pesticide data that is from a record-based source versus recall-based data relying on individuals’ memory. The second most common neurodegenerative disease affecting more than one million people in the U.S., Parkinson’s disease occurs when nerve cells in the substantia nigra region of the brain are damaged or destroyed and can no longer produce dopamine, a nerve-signaling molecule that helps control muscle movement. The new UCLA study is […]

(Beyond Pesticides, February 25, 2009) After three years of legal battle, the North Carolina Pesticide Board on February 19, 2009 fined Florida-based Ag-Mart Produce Inc. a substantially lower fine of $3,000 than the originally proposed $185,000, after deciding that it can only prove six of about 200 worker safety accusations that had been levied against the company. This comes less than a month after the unprecedented ruling against Ag-Mart in New Jersey, where the company was ordered to pay penalties of more than $931,000 for misusing pesticides and jeopardizing the health and safety of workers in its New Jersey farm fields and packing houses. The Florida-based company, described as one of the biggest pesticide offenders, has been accused of routinely exposing hundreds of workers to toxic chemicals. Investigators in North Carolina, Florida and New Jersey, the three states where the international company grows its tomatoes, scrutinized the company’s records and charged it with ignoring laws intended to keep workers safe from toxic pesticide residue. The investigators alleged workers were sent into the fields too soon after dangerous chemicals had been sprayed. The case started three years ago when some workers gave birth to babies with severe birth defects. One mother […]

(Beyond Pesticides, February 24, 2009) NIEHS staff scientist Freya Kamel, Ph.D., Harvard School of Public Health professor Chensheng (Alex) Lu, Ph.D., and Wake Forest University’s Center for Worker Health director Thomas Arcury, Ph.D. will speak as Science and Health panelists at Bridge to an Organic Future: Opportunities for health and the environment, the 27th National Pesticide Forum, April 3-4 in Carrboro, NC. Freya Kamel, Ph.D. Freya Kamel’s research interests focus on environmental determinants of neurologic dysfunction and disease, in particular, neurodegenerative disease. Dr. Kamel and her colleagues at the National Institute for Environmental Health Sciences (NIEHS) of the National Institutes of Health (NIH) examined the relationship of farm work-related exposures to subclinical neurobehavioral deficits in farmworkers. Deficits in neurobehavioral performance reflecting cognitive and psychomotor function related to the duration of work experience were seen in former as well as current farmworkers, and decreased performance was related to chronic exposure even in the absence of a history of pesticide poisoning. Thus, long-term experience of farm work is associated with measurable deficits in cognitive and psychomotor function. Dr. Kamel participated in work on the Agricultural Health Study (AHS), a large cohort study of licensed pesticide applicators and their spouses in Iowa and […]

(Beyond Pesticides, February 19, 2009) The Endocrine Exchange (TEDX) has released a new database on the prenatal origins of endocrine disruption, called Critical Windows of Development. It compares human development in the womb with laboratory research showing where and when low-dose exposures to chemicals have effects. The timeline currently charts three chemicals: dioxin, bisphenol A (BPA), and phthalates. TEDX plans to expand the database to include PCBs, PBDEs, DDT, and other endocrine-disrupting pesticides. Examples of conclusions from the prenatal exposure research include: BPA affects development of the male and female reproductive systems, increases susceptibility to breast cancer and alters behavior in adult animals; Phthalates decrease sperm production and increase body weight; and, dioxin affects male reproduction and the immune system. Before a baby is born it is exposed to a myriad of endocrine disrupting chemicals (EDCs). EDCs interfere with the delicate system of vital hormones, glands and organs that control how a baby develops and functions throughout life. EDCs such as BPA, dioxin and phthalates can penetrate the womb and cause adverse effects at extremely low exposure levels. These chemicals are found in water bottles, food cans, dental resins, cleaning products, cosmetics, fragrances, packaging and construction material, cars, planes, recreational […]

(Beyond Pesticides, February 5, 2009) Former chief environmental correspondent for The New York Times Philip Shabecoff and freelance journalist Alice Shabecoff will be making a rare public talk at Bridge to an Organic Future, the 27th National Pesticide Forum, April 3-4, 2009 in Carrboro, NC. They will be speaking Friday evening at the conference and signing copies of their new book, Poisoned Profits: The toxic assault on our children, during a reception immediately following their presentation. See registration information below. Based on more than five years of investigative research and reporting, Poisoned Profits reveals the cumulative scientific evidence connecting the massive increase in environmental poisons to the epidemic of disability, disease, and dysfunction among our nation ´s children. The authors conclude that the poisoning of the environment is as grave a threat to the future as any problem confronting our nation. Yet even as individual parents and pediatricians struggle to fight illness, one child at a time, the public remains in the dark about the enormity of this crisis. Why? Because, according to the authors, corporations control the system, molding laws to their liking. The book shines a light on the motives and means of corporate-paid lawyers, “product defense” companies, […]
