(Beyond Pesticides, January 17, 2013) The European Food Safety Authority (EFSA) yesterday presented its report which finds that the neonicotinoid class of insecticides poses unacceptable hazards to bees. The report concludes that certain crops treated with neonicotinoid chemicals –imidacloprid, clothianidin and thiamethoxam– are of “critical concern” for bee health. Beekeepers and environmental activists welcome these recent scientific findings that they say support a U.S. ban on these chemicals. According to Jay Feldman, Executive Director, Beyond Pesticides, “The EFSA report confirms what we have been asking EPA to recognize. Clothianidin and other neonicotinoids are highly toxic to bees, and should be banned by EPA and removed from the environment.” In its investigation, EFSA, which was tasked with assessing the risks associated with these chemicals to bee colony survival and development, found that systemic contamination of neonicotinoid-treated crops and contamination via dust place honey bees and the hives they return to at high risk. Exposure to contaminated dust pose a high risk to honey bees for all three neonicotinoids used on corn and certain other crops, as well as exposure to residues in nectar and pollen. High risks were also identified from exposure to guttation fluid from corn for thiamethoxam. EFSA considered […]

(Beyond Pesticides, January 16, 2013) Children living near chemical-intensive or conventional plantations in Costa Rica are exposed to twice as much of the insecticide chlorpyrifos compared to children living near organic plantations, a study reports. More than half the children, mostly from indigenous tribes- Ngäbe and Bribri – have a  higher daily exposures than allowed under U.S. federal standards. Chlorpyrifos is linked to neurological effects, especially in children, and is still permitted for use on crops. The study,  Indigenous children living nearby plantations with chlorpyrifos-treated bags have elevated 3,5,6-trichloro-2-pyridinol (TCPy) urinary concentrations, was lead by Berna van Wendel de Joode, PhD  (Central American Institute for Studies on Toxic Substances (IRET), Universidad Nacional, Heredia, Costa Rica). It was conducted in Costa Rica’s banana and plantain plantations in the Talamanca region, and  targeted villages situated nearby to the plantations where blue bags treated with chlorpyrifos are routinely used to protect banana and plantain crops from pests. Two villages under study are near plantations that use chlorpyrifos-treated bags, while the organic village is near several plantations  that use little or no insecticide. For 140 children, aged 6 — 9, mostly indigenous Ngäbe and Bribri, parent-interviews and urine samples were obtained. Chlorpyrifos’ environmental levels […]

(Beyond Pesticides, January 15, 2013)  Research published in the journal Environmental Monitoring and Assessment calls into question the value of environmental monitoring, such as water sampling,  on a  fixed date schedule (i.e., once per month), finding that this approach underestimates actual risks. These findings could have a significant impact on how we assess the safety of both endangered species and drinking water supplies. Researchers explain that, although insecticides are applied less often than herbicides and fungicides, they are usually applied in very large amounts when used in response to acute insect infestations. Scientists found that monitoring for insecticides at pre-set intervals, even weekly or daily, did not detect the occurrence of peak concentrations for these chemicals. Co-author of the study, Ralf Shulz, PhD, explains, “Accordingly, by way of example, on the basis of weekly monitoring of a typical agricultural stream none of the total of six insecticide concentration peaks per year described by model calculations is found. Daily sampling detects only two of the six peaks. Only event-related sampling enables the detection of all these peaks.” Authors of the study point to the need for events-related sampling, both to ensure more accurate detections are taken and to reduce costs. Events-related […]

(Beyond Pesticides, January 11, 2012) Environmentalists, farmworkers, and farmworker advocates have become increasingly uncomfortable with the new proposal for pesticide safety measures which does not include details on how the proposed rule will protect agricultural workers, farmers, and applicators. These sentiments stem from the concern that this may mean less stringent regulations than those originally proposed. In 2010, the U.S. Environmental Protection Agency (EPA) released a  document proposing Worker Protection Standards (WPS) that would determine ways to increase training, improve safety requirements, provide clear emergency information, and create strong protection for applicators. However, a recent EPA handout distributed  during a November 2012 Pesticide Program Dialogue Committee (PPDC) meeting downplays the details within those goals, and brings into question the agency’s  previous commitments. Advocacy groups have raised pointed complaints on the new document’s prose: “I have to agree that we are just really in the dark,” said one environmental group lawyer, “It is mysterious that it’s taken them so long to come up with a draft to propose, and the fact that they are being kind of tight-lipped about it and that even the very minimal detail about the proposal that was in the 2010 document disappeared from the 2012 […]

(Beyond Pesticides, January 8, 2013) Neurologists at the University of California, Los Angeles (UCLA) have published their latest research linking pesticide exposure to Parkinson’s disease. Appearing in the online edition of PNAS, the UCLA scientists’ work details the series of events that can occur after individuals are exposed to the pesticide benomyl, which was phased out in 2001. Researchers believe their findings on the series of events the pesticide sets in motion could be applicable even to Parkinson’s patients who have not been exposed to benomyl. According to scientists, exposure to benomyl prevents the enzyme aldehyde dehydrogenase (ALDH) from keeping in check a naturally occurring toxin in the brain called 3,4-Dihydroxyphenylacetaldehyde (DOPAL). Without ALDH regulating DOPAL, the toxin accumulates, damages neurons, and increases an individual’s risk of developing Parkinson’s disease. Researchers postulate that this process may be occurring in people with Parkinson’s who were never exposed to pesticides. The findings of this research provide insight into possible treatments to slow the disease, such as developing new drugs to protect ALDH activity. Although the exact cause of Parkinson’s is still unknown, until this research scientists were focusing in on the protein a-synuclein as a pathway to the disease. The protein, present […]

(Beyond Pesticides, January 4, 2013) On December 31, 2012, the U.S. Environmental Protection Agency (EPA) proposed to clarify its labeling requirement for disclosure of all active and inert ingredients in “minimum risk pesticide products,” exempt from registration under Section 25 (b) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). The rule (77 FR 250) reorganizes the list of eligible active and inert ingredients by adding identifiers that will clarify for the public, and more importantly for federal and state inspectors, which ingredients are permitted in minimum risk pesticide products. The modification would require labels to use common chemical names in the list of ingredients as well as the contact information for the manufacturer. The lack of clarity on minimum risk pesticide product labels in the past has made it difficult for enforcement officials who must use their own judgment on the applicability of vague descriptors such as cedar leaf oil and cedar wood oil, which are exempt under the current listing of “Cedar Oil” under CFR Section 152.25. While EPA has attempted to improve labeling clarity of minimum risk pesticide products by updating its website, stakeholders have found the measure insufficient. Regulatory Background Currently, EPA is empowered under FIFRA […]

(Beyond Pesticides, December 19, 2012) The Congressional Research Service (CRS) issued its overview report, Bee Health: The Role of Pesticides, in response to a congressional request for more information on the connection between declines in bee populations, colony collapse disorder (CCD) and pesticides, particularly neonicotinoids. The 23-page report, dated December 11, 2012, summarizes the range of scientific studies and regulatory activities without offering a critique of what bee health advocates have identified as serious deficiencies in the regulatory review process and compliance with the pesticide registration law. The review gives equal standing to independent and industry science. The CRS report identifies a range of issues regarding: 1. Changes to managed and wild bee populations (indicating limited information); 2. Factors that are documented to impact bee health, including pesticides, pests and diseases, diet and nutrition, genetics, habitat loss, and beekeeper issues, highlighting that there are multiple exposure pathways that may work synergistically; 3. Scientific research on the role of pesticides; and, 4. Current research and regulatory activity regarding neonicotinoids, a neurotoxic insecticide impacting bees. The report reviews the ‘state of play’ on the issue of bee declines and finds that there are reported to be many factors that contribute to the […]

(Beyond Pesticides, December 18, 2012) Certain pesticide manufacturers are gearing up to try to block EPA’s attempts to cancel certain rodent poisons that are known to be hazardous to children and wildlife, including endangered species. After more than a decade of research and review, and an unacceptably high number of poisoning incidents, EPA has acknowledged that certain active ingredients are too dangerous to remain on the market, and is now requiring all remaining over-the-counter rodent control products to be in secured, tamper-resistant bait stations to reduce the incidents of accidental exposure to children. Granular and powdered products will be banned. But certain chemical companies are refusing to comply with EPA’s order and have indicated that they will challenge the agency’s decision. Every year, more than 10,000 children are exposed to rodent poison products, and the majority of calls to poison control centers concern children under the age of three. Despite the availability of alternatives, industry is leading a campaign against EPA’s decision, trying to scare communities into believing that they will be overrun with rodents and infested with disease if their products are not used. Meanwhile, less toxic rodent control products and those secured in bait stations are available, effective, […]

(Beyond Pesticides, December 17, 2012) Pets are frequently exposed to toxic chemicals used for lawn care, bug sprays, flea and tick products, and rodenticides. Recently, a dog ingested a zinc phosphide based pellet rodenticide, and threw up these toxic chemicals, creating a toxic gas that caused respiratory stress for four of the veterinary staff where the dog was being treated. The incident happened in Vail Valley Animal Hospital in Edwards, Colorado on December 7, and led to one emergency room veterinarian and three technicians being sent to the hospital. Sadly the dog did not survive after releasing this toxic gas. This is not the first incident of phosphine gas exposure at a veterinary clinic as a total of four have been reported from 2006 to 2011 in Michigan, Iowa, and Washington. When zinc phosphide is ingested and comes in contact with water it forms a poisonous gas. In a statement, the local fire protection district explained, “When the dog vomited, this released the [phosphine] gas as the pesticide had mixed with the contents in the dog’s stomach.” According to the Centers for Disease Control and Prevention (CDC), inhalation of high concentrations of phosphine gas can be deadly and can cause […]

(Beyond Pesticides, December 14, 2012) Decision making advice by the Advisory Committee on Pesticides (ACP) and insecticide regulator, the Department for Environment, Food, and Rural Affairs (Defra), were harshly criticized on Wednesday by Members of Parliament (UK), as they discussed the problems associated with neonicotinoids, a group of neurotoxic insecticides linked to serious declines in bee and pollinator populations. The meeting was attended by Members of Parliament, members of the Advisory Committee on Pesticides, Lord de Mauley, the Parliamentary Under-Secretary of State, the Department for Environment, the Food and Rural Affairs and officials, bringing neonicotinoids and their impact on bees to the attention of the international community as well as at home. The discussion focused on the evidence used to make a decision on the allowance of neonicotinoids and plans for the future. ACP members indicated that evidence for future draft plans would be based on new studies developed in 2012 on the effects of neonicotinoids at the colony level, as well as the impact of neonicotinoids exposure in field tests, rather than in the lab. Research will likely fill the extant data gaps, the most important of which were identified by officials of Defra, the environmental regulatory agency in […]

(Beyond Pesticides, December 10, 2012) Long-term low-level exposure to organophosphate pesticides produces lasting damage to neurological and cognitive functions, according to researchers at University College London (UCL). This research pulls data from 14 studies over the past 20 years, including more than 1,600 participants, in order to provide a quantitative analysis of the current literature on these dangerous chemicals. Lead author of the study, Sarah Mackenzie Ross, Ph.D., notes, “This is the first time anyone has analyzed the literature concerning the neurotoxicity of organophosphate pesticides, using the statistical technique of meta-analysis.” UCL’s systematic review, published in the journal Critical Reviews in Toxicology, comes to an unsettling conclusion about the hazards of constant low-level occupational exposure to organophosphates. The study notes, “The majority of well designed studies found a significant association between low-level exposure to [organophosphates] and impaired neurobehavioral function which is consistent, small to moderate in magnitude and concerned primarily with cognitive functions such as psychomotor speed, executive function, visuospatial ability, working and visual memory.” In other words, low-level exposure had significant detrimental effect on working memory and information processing. The researchers are hopeful that the results of their analysis will be used to inform governments performing reviews on the […]

(Beyond Pesticides, December 6, 2012) A study published in the December issue of Annals of Allergy, Asthma and Immunology finds that exposure to dichlorophenols may be associated food allergies. Dichlorophenols are used as an intermediary in the manufacturing of some of the most commonly used pesticides, such as 2,4-D, and are also used to chlorinate drinking water. This study may help explain in part why food allergies are on the rise in the U.S. and already affect 15 million Americans. Lead researcher Dr. Elina Jerschow and her associates analyzed the urine of 10,348 Americans who were participants in the U.S. National Health and Nutrition Examination Survey (NHANES) of 2005-2006. Of the over 10,000 surveyed, 2,548 had detectable amounts of dichlorophenols in their urine, and 2,211 of those participants were included in the study. Out of these 2,211 people, 1,427 were found to have some form of either food or environmental allergy. Participants with higher levels of dichlorophenols are more likely to have allergies then those with low levels present in their urine. Researchers in this study argue that by consuming high levels of dichlorophenols individuals are altering the composition of bacteria in their stomachs. By over consuming dichlorophenols individuals are […]

(Beyond Pesticides, December 3, 2012) The Food and Drug Administration (FDA) has denied a 2010 petition filed by the National Resources Defense Council (NRDC) and Pesticide Action Network North America (PAN) to ban the insecticide lindane, which is harmful to human health and ineffective in controlling lice and scabies. Pressure had been mounting on FDA to halt the pharmaceutical use of lindane as, in addition to this petition, Congressman Edward J. Markey (D-Mass.), senior member of the Energy and Commerce Committee, asked FDA to stop the pharmaceutical use of lindane this past summer. Because of FDA’s decision, lindane is still an active ingredient in pharmaceutical insecticide products such as lice shampoos and lotions. Lindane was formerly used in agricultural insecticides until it was banned by the Environmental Protection Agency (EPA) for use on crops in 2006. FDA regulates pharmaceuticals that contain insecticides and pesticides, such as triclosan, that are in cosmetics. Over 160 countries including the United States have signed on to the Stockholm Convention on Persistent Organic Pollutants (POPs) in 2001 which aims to eliminate or restrict the production and use of persistent organic polluntants. Lindane along with nine other chemcials was added to this list on May 9th […]

(Beyond Pesticides, November 30, 2012) A health care institution is weighing in to warn people about potential dangers of genetically engineered (GE) food. On the heels of the American Academy of Pediatrics’ warning on pesticides, the nation’s largest nonprofit health care plan, Kaiser Permanente, has published in its print newsletter, Partners in Health, tips on limiting exposure to genetically engineered food. In the Fall 2012, Kaiser Permanente has published an article, “What you need to know about GMO: Limit exposure to genetically engineered organisms with these tips.” This discussion in the health care sector is part of a growing involvement by health care practitioners in environmental health concerns related to pesticides and genetic engineering of the food supply. While Canadian medical groups have warned the public about the dangers of pesticides and supported phase-outs, institutions representing the medical community in the U.S. have been more reserved. In 2004, the Ontario College of Family Physicians (OCFP) in Canada strongly recommended that people reduce their exposure to pesticides wherever possible, after releasing a comprehensive review of research on the effects of pesticides on human health. OCFP’s Systematic Review of Pesticide Human Health Effects shows consistent pesticide links to serious illnesses such as […]

(Beyond Pesticides, November 28, 2012) Earlier this year the maker of the fumigant methyl iodide indicated it would stop producing the toxic chemical. Now, the U.S. Environmental Protection Agency (EPA) and the registrant, Arysta LifeScience North America, LLC have entered into a Memorandum of Agreement to formally terminate all agricultural use of methyl iodide in the U.S. by the end of 2012 and ultimately remove all methyl iodide products from the U.S. market. EPA is opening a 30-day comment period for Arysta’s request for voluntary cancellation of all of the company’s methyl iodide product registrations, as stipulated in the agreement. Methyl iodide, or iodomethane, has been registered since 2007 for use as a pre-plant soil fumigant to control pests in soil where fruits, vegetables, ornamental plants, and turf are to be grown. In March 2012, Arysta, the sole registrant, announced its plans to immediately suspend all sales of its methyl iodide MIDAS ® products in the U.S. Under the recently signed agreement and the voluntary cancellation request, all of Arysta’s existing methyl iodide end-use product registrations will be cancelled and use of existing stocks in the U.S. will be prohibited effective December 31, 2012. Further distribution and sale of methyl […]

(Beyond Pesticides, November 27, 2012) On Monday, the American Academy of Pediatrics (AAP) released a landmark policy statement, Pesticide Exposure in Children, and an accompanying technical report on the effects of pesticide exposure in children. In the documents, released in the December 2012 issue of Pediatrics magazine and online on November 26, AAP makes note of the current shortfalls in medical training, public health tracking, and regulatory action on pesticides. Acknowledging the risks to children from both acute and chronic effects, AAP’s report provides recommendations to both pediatricians and government health agencies. AAP’s policy statement comes on the heels of an October 2012 report citing the benefits of eating organic food in order to reduce pesticide exposure. Lead authors on the documents for the AAP’s Council on Environmental Health are James R. Roberts, MD, MPH, Medical University of South Carolina, and Catherine J. Karr, MD, PhD, University of Washington. AAP’s statement notes that, “Children encounter pesticides daily and have unique susceptibilities to their potential toxicity.” The report discusses how kids are exposed to pesticides every day in air, food, dust, and soil. Children also frequently come into contact with pesticide residue on pets and after lawn, garden, or household pesticide […]

(Beyond Pesticides, November 26, 2012) The U.S Environmental Protection Agency’s (EPA) risk assessment process does not account for cumulative dietary exposure to the multitude of pesticides on conventional foods. The agency typically analyzes the exposure risk associated with each pesticide on an individual basis, except for those determined to have a common mechanism of toxicity. In light of these gaps in America’s regulatory process, researchers at UC Davis and UCLA in Cancer and non-cancer health effects from food contaminant exposures for children and adults in California: a risk assessment conducted an analysis of the toxics children and adults are exposed to through a normal diet. Rainbow Vogt, Ph.D., lead author of the study published in the journal Environmental Health, explains, “We focused on children because early exposure can have long-term effects on disease outcomes.” Researchers preformed their risk assessment by estimating exposure to food contaminants based on self-reported food frequency data for eleven toxic compounds- acrylamide, arsenic, lead, mercury, chlorpyrifos, permethrin, endosulfan, dieldrin, chlordane, DDE, and dioxin. Data was drawn from the 2007 Study of the Use of Products and Exposure-Related Behavior, which examines behaviors that influence exposure to toxicants in the home environment. Normal consumption patterns were then measured […]

(Beyond Pesticides, November 21, 2012) The National Organic Coalition (NOC) yesterday sharply condemned recommendations contained in the final report of the Advisory Committee on Biotechnology and 21st Century Agriculture (AC21), a group appointed by the U.S. Department of Agriculture (USDA) to address transgenic contamination of organic and non-genetically engineered (GE) crops. Of particular concern in the report is the recommendation that organic and non-GE conventional farmers pay for crop insurance or self-insure themselves against unwanted GE contamination. NOC strongly asserts that this proposal allows USDA and the agricultural biotechnology industry to abdicate responsibility for preventing GE contamination, while making the victim of GE pollution pay for damages resulting from transgenic contamination. “The AC21 report takes responsibility for GE contamination prevention out of the hands of USDA and the biotech industry where it belongs and puts it squarely on the backs of organic and non-GE farmers,” said Andrew Kimbrell, executive director at Center for Food Safety and a NOC member. “This ill-conceived solution of penalizing the victim is fundamentally unjust and fails to address the root cause of the problem – transgenic contamination.” In August 2011, USDA convened AC21 and charged it with identifying compensation mechanisms to address GE contamination.

(Beyond Pesticides, November 20, 2012) Thanksgiving offers an opportunity for family and friends to eat, drink and be thankful for the bounty of the organic harvest. Unfortunately, there are a host of pesticides, genetically engineered materials, and others in conventional Thanksgiving foods that not only impact human health, but threaten the environment. Read below for some easy tips and suggestions for a healthful Thanksgiving day feast. Organic, free-range, and local turkeys The turkey is the symbol of a traditional Thanksgiving meal. However, turkeys are often fed grains treated with pesticides, medicated with antibiotics, and engorged with steroids and hormones. Additionally, turkeys are often fed an inorganic arsenic, a known carcinogen, which is used to promote growth and for pigmentation. In order to avoid all these, your best bet is to invest in an organic free-range turkey (pictured right), which is free of hormones, steroids or antibiotics. Want to forgo the turkey altogether? Be sure to choose an organic meatless option. Avoid Genetically Engineered Food: Go Organic There are additionally, a number of Thanksgiving products that probably contain genetically-engineered (GE) ingredients (although the formulations are often considered proprietary trade secrets). According to GMO Inside, some common GE foods used during Thanksgiving […]

(Beyond Pesticides, November 14, 2012) For years, scientists have shown that pesticide exposures are linked to the onset of Parkinson’s disease. Now a new study by researchers at University of California, Los Angeles, (UCLA) finds that exposure to pesticides and suffering a head injury are associated with a three-fold increase in one’s chances of developing Parkinson’s disease. Parkinson’s disease is the second most common neurodegenerative disease, and 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. People with Parkinson’s disease have a variety of symptoms, including loss of muscle control, trembling and lack of coordination. Over time, symptoms intensify. At least one million Americans have Parkinson’s and about 50,000 new cases are diagnosed each year. The study, “Traumatic brain injury, paraquat exposure, and their relationship to Parkinson disease,” published in the journal Neurology surveyed more than 1,000 adults ages 35 and older who lived in central California. Some 357 of the participants were diagnosed with Parkinson’s disease. Participants with the disease were nearly twice as likely as those without the disease to report having had a head injury in […]

(Beyond Pesticides, November 8, 2012) In response to an emergency exemption granted by the U.S. Environmental Protection Agency (EPA) to allow the unregistered use of the herbicide fluridone on cotton in order to control glyphosate-resistant weeds, the agency announced in the Federal Register Monday that it is establishing time-limited tolerances for residues of the chemical on food. Because resistance to herbicides in genetically engineered crops is predictable and expected, Beyond Pesticides has challenged EPA’s use of the emergency exemption provision of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), Section 18, in this and other similar cases. According to EPA, of the glyphosate-resistant weeds, Palmer amaranth has become the most severe weed problem in Arkansas cotton production. It can reduce yields of cotton by more than 50 percent if there is a density of at least 10 of these weeds per row. Over 95% of Arkansas cotton and 80% of soybeans is genetically engineered (GE) to be glyphosate tolerant. Because glyphosate is the base herbicide used for weed control in this region, economic loss is expected on nearly 25% of acres grown. Over-reliance on herbicide-tolerant GE crops have caused the spread of resistant weeds that force farmers on the pesticide […]

(Beyond Pesticides, November 5, 2012) An ongoing study in the United Kingdom has found that in areas of southern England up to 75% of the rat population is potentially resistant to the common rodenticides warfarin, bromadiolone, and difenacoum. Pesticide resistance was documented in rats as early as the 1950’s. Common rodenticides used in homes already pose a high risk to human and animal health, but as more rodents become resistant to these pesticides individuals face the greater danger of pest control companies using higher doses of more lethal chemicals to deal with “super rats.” The rodenticides being tested in this study are anticoagulant pesticides that work by blocking vitamin K-dependent synthesis of the blood clotting substance prothrombin. These chemicals cause the animal to bleed to death internally. Not only are these chemicals toxic to mammals, but they are often used in dangerous loose bait and pellet traps. These traps put children at particular risk for exposure because the products are typically placed on floors, and young children sometimes put bait pellets in their mouths. The American Association of Poison Control Centers annually receives between 12,000 and 15,000 reports of children under the age of six being exposed to these types […]
