(Beyond Pesticides, February 15, 2019)Â A study, published in January 2019 in the journal Environmental Health, demonstrates that consumption of organic foods reduces significantly the levels of synthetic pesticide residues in the bodies of U.S. children and adults. Pesticide residues are found four times as frequently in conventionally grown food as in organically produced foodstuffs. Although the number of subjects in this study was relatively small, the results point to the importance of organics, and add to the evidence that organic food production and consumption are key to protecting human health. Study subjects comprised members of racially diverse families â from Oakland, Minneapolis, Baltimore, and Atlanta â who did not typically consume an organic diet. Study participants, ages 4 to 52, ate their typical diet of conventionally grown foods for five days; for the following six days, they switched to a certified organic diet (provided by researchers) for consumption at home, work, school, or daycare, including all foods and beverages other than water. Urine samples were gathered prior to the âorganicâ days, and first thing on the morning after those six days. Fourteen different pesticides and metabolites were present in all participantsâ urine in the âpre-organicâ analysis; following the organic diet […]

(Beyond Pesticides, January, 23, 2019) Individuals that have been acutely poisoned by pesticides at some time in their life may be more likely to lose their sense of smell, according to a recent study published in Environmental Health Perspectives. Â Researchers focused on the effect of high pesticide exposure events (HPEE), such as a pesticide spill or other incident, on a farmersâ ability to smell later in life. This is the first study to indicate pesticide exposure may result in olfactory impairment. Farmers from Iowa and North Carolina enrolled in an ongoing U.S. Agricultural Health Study have been asked about their pesticide use roughly every 5 to 6 years since 1993. In the most recent survey, taken from 2013-2015, farmers were asked additional questions about HPEE in their lifetime and whether they had a significantly decreased or impaired sense of smell. âStudying farmers gives us more reliable data on pesticide exposures than if we had studied the general population,â says Honglei Chen, MD, PhD, lead author and professor of epidemiology at Michigan State University in a press release. âBecause they use pesticides more and itâs part of their job, theyâre more likely to remember what pesticides they used and in cases […]

(Beyond Pesticides, January 14, 2019)Â Â A petition submitted on January 7 by the Center for Biological Diversity calls on the National Marine Fisheries Service (NMFS) and the U.S. Fish and Wildlife Service (FWS) to initiate rulemaking to proscribe nearly all pesticide use in areas that are deemed critical habitat for endangered species. It asks these federal agencies to use the authority they have under the 1973 Endangered Species Act (ESA) to protect wildlife from the threats represented by pesticides â which threats both agencies have long recognized. The language of the ESA says its purpose is âto provide a means whereby the ecosystems upon which endangered species and threatened species depend may be conserved.â In its press release on the petition, the Center for Biological Diversity (CBD) notes that it comes âafter decades of intransigence by the Environmental Protection Agency, which has refused to comply with the legal mandates of the Endangered Species Act to protect the nationâs most imperiled species from highly toxic pesticides like chlorpyrifos and atrazine that are known to harm wildlife.â CBD environmental health director Lori Ann Burd said, âPesticides pose a devastating danger to endangered wildlife, from coast to coast. If the EPA isnât going to […]

(Beyond Pesticides, January 8, 2019) At the end of December, the U.S. Department of Agriculture (USDA) finalized its rule regarding the disclosure of genetically engineered (GE) ingredients in consumer foods. After years of local, state and federal pressure to implement a clear, concise labeling requirement for GE foods, advocates say USDAâs rule is a failure, and a capitulation to agrichemical corporations that promote GE farming systems. According to U.S. Representative Chellie Pingree (D-ME), speaking with the Portland Press Herald, the new rule is âan insult to consumers.â She said, âThese labels should give people the facts of whether ingredients in their food have been genetically altered, plain and simple.â Rather than the plain and simple language urged by Rep Pingree and other GE labeling advocates, USDA determined to move forward with muddled verbiage that is certain to confuse consumers. GE products will not defined by a term Americans are familiar with, such as GE or GMO. Instead, the term USDA will require on product labels is âbioengineered.â USDA is allowing companies to choose one of the following methods to alert consumers to the presence of GE ingredients in their foods: Inclusion of a âbioengineeredâ or âderived from bioengineeringâ symbol alongside […]

(Beyond Pesticides, December 11, 2018) Meltwater and runoff from Alaskan glaciers contain detectable levels of organochlorine pesticides that bioconcentrate in fish and put individuals at risk, according to a new study from researchers at the University of Maine (UMaine). DDT, lindane, and other organochlorines have been detected throughout the world, even in natural areas thought to be untouched, and pristine. As UMaine scientists show, the atmospheric transport and ubiquitous deposition of these pesticides continues to pose risks to U.S. residents long after regulations banned their use. Although most of the highly toxic class of organochlorine pesticides like DDT were banned in the early 1970s, some chemicals retained certain uses. Lindane, for example, had its pest management uses phased out gradually until 2007, but is still allowed today as a scabies and lice shampoo. While use of these pesticides has declined in the U.S., much of the developing world, including many Asian countries, such as China, India, and North Korea, still report use. This results in atmospheric transport of the pesticides, and relevant to the UMaine research, increases the likelihood that the chemicals will eventually be deposited onto Alaskan glaciers through snow or rain. The UMaine research team investigated the amount of […]

(Beyond Pesticides, November 27, 2018) The U.S. Environmental Protection Agency (EPA) ignored the input of an expert weed scientist on the controversial herbicide dicamba, bending to Bayerâs Monsanto and the pesticide industry, according to emails obtained by the Arkansas Democrat and Chronicle (ADC) through a Freedom of Information Act request. The scandal centers on the recent re-approval of the pesticide, a highly volatile and drift-prone herbicide that has become a serious problem for many farmers and state regulators. As top-level EPA officials continue to work with industry to subvert their own agencyâs scientific findings, more and more consumers are moving to organic products in order avoid the pesticide risks government regulators ask consumers to accept. Emails ADC received indicate that Jason Norsworthy, PhD, a weed scientist with the University of Arkansas, worked closely with Bayerâs Monsanto in conducting field trials this past summer, but found high volatility and drift of the companyâs new dicamba-based herbicide XtendiMax. The product was developed in the face of widespread resistance to glyphosate-based herbicides in genetically engineered (GE) farm fields. However, recent accounts from farmers in the south and midwest indicate that, not only is the switch to dicamba unhelpful in eliminating drift and reversing escalating weed resistance, its […]

(Beyond Pesticides, November 22, 2018) As we sit down for our Thanksgiving meal with friends and family, let us all take a moment to give thanks to the hardworking individuals that made our meal possible. Farmworkers and farmers toil day in and day out in the field, growing the staples that make the holiday special. This year, farmworkers need our support more than ever, as powerful forces within the agrichemical industry continue to influence decisions that deny them the protections and compensation they deserve for their hard work. After a proposal under the Obama administration to update farmworker protections following decades of inaction, former Environmental Protection Agency Administrator Scott Pruitt reversed course and decided to delay implementation. The new policy, representing the bare minimum required to improve the deplorable conditions many farmworkers confront, would have raised the age to apply highly toxic pesticides to 18, and improved training materials, among other basic changes. The agency then determined in December 2017 that it would not only refuse to implement changes as planned, but potentially do away with them all together. Allowing minors to spray toxic pesticides was put back on the table, as were 25 to 100 ft exclusion zones after […]

(Beyond Pesticides, November 14, 2018) Monarch butterflies are in the midst of a staggering decades-long population decline that has rapidly accelerated since 2005, research published by an international team of scientists and the University of Florida last month indicates. According to data meticulously collected by researchers, monarchs making their way to central Florida after emerging from their breeding grounds in Mexico have declined by 80% over the last decade and a half. This is roughly the same time frame at which beekeepers began to see precipitous declines in managed honey bee colonies. Researchers point to industrial development and increasing pesticide use as factors that have accelerated the decline of this iconic species. “A broad pattern is that 95 percent of corn and soybean products grown in the U.S. are Roundup Ready crops that resist glyphosate,” said study coauthor Earnest Williams, PhD, of New Yorkâs Hamilton College in a press release. “That has a national impact. What’s really needed are patches of native vegetation and nectar sources without pesticides. It’s not just for monarchs but all pollinators.” Beginning in 1985, renowned monarch expert Lincoln Brower, PhD and his team monitored monarch populations at a pesticide-free cattle pasture south of Gainesville, FL.

(Beyond Pesticides, October 18, 2018) Pesticide residue doesnât announce itself âit isnât colored, it doesnât glow or reflect light, and after an initial application doesnât put out a discernible odor – but it is likely ubiquitous in rural U.S. homes, according to a study published by Cornell University researchers late last month. The study is a warning specifically to households with young children, who are at increased risk of health effects from even minute levels of pesticide exposure. âNumerous health problems occur from exposure to pesticides, such as cancer, birth defects, leukemia and ocular [vision-related] toxicity, among a number of other health issues,â said Joseph Laquatra, PhD, coauthor of the research. âHouseholds with crawling toddlers should be concerned, as toddlers will accumulate pesticide residues on their hands and then ingest them due to hand-to-mouth behaviors.â Researchers focused in on 132 households in rural counties of New York State that agreed to test for pesticide residue inside their home. Wipe samples were collected from both carpeted and non-carpeted areas, and tested for pesticides used commonly as part of agricultural production in the region. The pesticides analyzed included 15 compounds ranging from organophosphates like chlorpyrifos and malathion, to synthetic pyrethroids like resmethrin, […]

(Beyond Pesticides, September 4, 2018) Close on the heels of the recent landmark California decision against Monsanto, maker of the glyphosate-based pesticide Roundup, Vietnam has demanded that the company pay damages to the many victims of its Agent Orange herbicide and defoliant, which Monsanto supplied to the U.S. military during the Vietnam War. (Monsanto was not the only U.S. manufacturer of the compound; there were nine in total.) U.S. forces, in a program dubbed Operation Ranch Hand, used more than 13 million gallons of the compound in Vietnam â nearly one-third of the 20 million gallons of all herbicides used during the war in Laos, Cambodia, and Vietnam. In Vietnam alone, 4.5 million acres were impacted by Agent Orange. Nguyen Phuong Tra, a spokesperson for Vietnamâs foreign ministry, said, âThe [U.S.] verdict serves as a legal precedent which refutes previous claims that the herbicides made by Monsanto and other chemical corporations in the U.S. and provided for the U.S. army in the war are harmless. . . . Vietnam has suffered tremendous consequences from the war, especially with regard to the lasting and devastating effects of toxic chemicals, including Agent Orange.â Around the world, the U.S. case may be sparking […]

(Beyond Pesticides, August 12, 2018) In a stunning legal victory for a man who contracted non-Hodgkin lymphoma (NHL) after using the herbicide glyphosate (Roundup), groundskeeper Dewayne Johnson won a $289 million jury verdict against the chemical’s manufacturer, Monsanto. The jury on August 10, 2018 awarded the 46-year old Mr. Johnson $39 million in compensatory damages, and $250 million in punitive damages. The jury found that Monsanto acted with âmalice or oppression.â “We applaud and thank Mr. Johnson, and his family and attorneys, for persevering in this litigation, which sets a critically important standard for protecting people’s right not be poisoned by pesticides in the marketplace,” said Jay Feldman, executive director of Beyond Pesticides. Mr. Feldman continued: “While we know that the jury verdict cannot restore Mr. Johnson’s health, we believe that the verdict is a clarion call to manufacturers that ignore the devastating impact that their products can have on unsuspecting workers, consumers, and families. We look forward to the day in the not-too-distant future when we recognize as a society that products like glyphosate (Roundup) are not necessary, and effective and affordable land and building management can be achieved without toxic chemicals. The case should also signal to all […]

(Beyond Pesticides, August 3, 2018) Documents made public in late July show that the U.S. Environmental Protection Agency (EPA) let Monsanto write its own rules after farmers and the public raised red flags over crop damage and contamination caused by its new line of dicamba herbicides. As part of the discovery process initiated by a lawsuit against EPAâs approval of its new dicamba product, called âXtendiMax with Vapor Grip Technology,â emails released (start at p. 147) show Monsanto line-editing regulations first proposed by EPA. This is only the latest in a long string of instances where EPA has worked hand in glove with the agrichemical industry it is charged with overseeing. When the new regulations were released, Beyond Pesticidesâ noted broad criticism that the changes will not adequately address the damage caused by this new herbicide. The newest product in the agrichemical industryâs predictable trajectory toward increasingly toxic cropping systems, XtendiMax was developed to be sprayed on corn and soy genetically engineered to tolerate the herbicide. As its flagship Roundup Ready products have failed to control resistant weeds in farm fields throughout the U.S., Monsanto and others in the agrichemical industry continue to reach back towards older, more toxic pesticides […]

(Beyond Pesticides, August 2, 2018) Weed scientists from the University of Missouri (UM) have just published evidence of a water hemp population resistant to six different herbicides. The study is sending shock waves throughout the chemical-intensive agricultural community, particularly in light of the plant’s resistance to 2,4-D. In its reporting on the study, KTIC Rural Radio begged the question, âIf weâre already seeing 2,4-D resistance now, what will happen when use of the herbicide becomes even more commonplace?â KTIC is referring to the impending commercialization of products like Enlist Duo, developed by DowDupont in an attempt to address widespread weed resistance to glyphosate. Enlist Duo is an herbicide containing both glyphosate and 2,4-D, and is intended to be sprayed only on crops genetically engineered (GE) to tolerate exposure to both chemicals. However, with growing reports like this, many farmers may begin to rethink their approach. In 2014, a farmer contacted UM indicating that water hemp was not responding to 2,4-D during a regular âburndownâ the farmer conducted before planting a new crop. (Chemical-intensive farmers will often use a synthetic herbicide to clear their field for new plantings.) The farmer had also used other herbicides, fomesafen and glyphosate, in this process […]

(Beyond Pesticides, July 19, 2018)Â A variety of bentgrass, genetically engineered by Scotts Miracle-Gro and Monsanto to tolerate the glyphosate herbicide Roundup, escaped from an experimental field planting in Eastern Oregon 15 years ago, and continues to plague area farmers. Bentgrass is prized by those who maintain golf course greens because of its fine texture and habit of spreading in even, horizontal mats. But the genetically engineered (GE) version has become a giant annoyance for farmers and other growers who battle its spread through the irrigation systems of Malheur County in eastern Oregon. The escape of this GE version of Agrostis stolonifera is especially alarming in Oregon, the grass seed capital of the world. The GE grass showed up after crossing the Snake River from where it had been planted in seed fields in Idaho, despite the fact that the USDA had not approved its release into the seed market. By 2010, farmers and others found it spreading in mats across most of the irrigation canals and ditches that snake across Malheur County. It is now found in Jefferson County, Oregon, and Canyon County, Idaho, as well. The growth habit of the perennial grass is what greenskeepers love, but its persistent […]

(Beyond Pesticides, June 13, 2018) On June 6, 2018, the New York State Department of Environmental Conservation (NYSDEC) released its final policy for the disclosure of cleaning product ingredients under its Household Cleansing Product Information Disclosure Program. The program will require full disclosure of ingredients on product labels or manufacturer website for all products sold in the state, as well as the identification of chemicals of concern. NYSDEC states the program is intended to protect consumers from harmful chemicals in household products. The Household Cleansing Product Information Disclosure Program requires manufacturers of cleaning products sold in New York to disclose chemical ingredients and identify any ingredients that appear on authoritative lists of chemicals of concern on their websites. Companies must also provide a list of links to productâs ingredients to NYSDEC. New York states that it âwill be the first state in the nation to require such disclosure and the Stateâs program goes beyond initiatives in other states by requiring the robust disclosure of byproducts and contaminants, as well as chemicals with the potential to trigger asthma in adults and children.â Products included in the program are cleaning products like soaps and detergents containing surfactants, emulsifying agents and used primarily […]

(Beyond Pesticides, May 31, 2018) Deforestation in tropical regions helps spread malaria, concludes a recent research study of the Amazon Rainforest. Published in Natureâs open-access journal, Scientific Reports, the study details researchersâ work, from 2009â2015, comparing patterns of deforestation to rates of malaria in nine states in the Brazilian rainforest. Investigators found that the highest malaria incidence concentrated in impacted patches of forest â areas deforested or otherwise degraded from an unmanaged or more-natural state. These medium-sized patches (from .1 to 5 sq. km. in size) seem to be the âsweet spotsâ at which wood extraction activity (logging, charcoal production, et al.) correlate most strongly with malarial infection rates. The researchers suggest that the finding is perhaps related to the habitat preferences of the primary malaria vector in the region, Anopheles (Nyssorhynchus) darlingi, which breed most happily in shady, watery, edges of forest habitat. Sixty of the 380 mosquitoes in the genus Anopheles can transmit the malaria parasites. Deforestation fragments the forest landscape, creating more forest âedges,â which means more places for mosquitoes to breed. This fragmentation may also help malaria-carrying mosquitoes spread to other areas as adults: âThe new [fragmented] landscape delineated by the pattern of deforestation and soil occupation may favor […]

(Beyond Pesticides, May 21, 2018)Â Â 490,000 Pounds of Toxic Pesticides Sprayed on National Wildlife Refuges in 2016 The nationâs 562 national wildlife refuges play a critical role in protecting fish, plants, and other wildlife. They include forests, wetlands, and waterways vital to thousands of species of plants and animals, including 280 that are protected under the Endangered Species Act. However, private chemical-intensive commercial farming of crops like corn, soybeans, and sorghum has become common on refuge lands, with the increasing use of highly toxic pesticides that threaten the long-term health of sensitive habitats and the creatures who depend on them. The Center for Biological Diversity (CBD) estimates that 490,000 pounds of pesticides were applied to commodity crops like corn, soybeans, and sorghum grown in national wildlife refuges in 2016, the most recent year for which data are available. Tell FWS to take toxic pesticides out of wildlife refuges. The nearly half million pounds of pesticides used on wildlife refuges in 2016 include 2,4-D, dicamba, and paraquat, all of which are toxic to fish, amphibians, crustaceans, and other animals. Also included are 116,200 pounds of glyphosate, the herbicide that has caused widespread decreases in milkweed plants, helping to trigger the 80 percent […]

(Beyond Pesticides, May 15, 2018) According to a new report from the Center for Biological Diversity (CBD), hundreds of thousands of pounds of pesticides are sprayed on lands that are designated as refuges for wildlife and protected under U.S. law. Approximately 490,000 pounds of pesticides have been sprayed on crops grown in national wildlife refuges in 2016 alone. Pesticide use in these sensitive areas poses risks to pollinators, aquatic organisms, migratory birds, and other wildlife on refuges that were created to protect them. The report, No Refuge, released last week, analyzes pesticide use on national wildlife refuges using records obtained through a Freedom of Information Act request. The report finds that in 2016 more than 270,000 acres of refuge lands were sprayed with pesticides for agricultural purposes. Five national wildlife refuge systems are identified as most reliant on pesticides for agriculture: Klamath Basin National Wildlife Refuge Complex in California and Oregon, with 236,966 pounds of pesticides; Central Arkansas Refuges Complex in Arkansas, with 48,725 pounds of pesticides; West Tennessee Refuge Complex in Tennessee, with 22,044 pounds of pesticides; Tennessee National Wildlife Refuge Complex in Tennessee, with 16,615 pounds of pesticides; and, Chesapeake Marshlands National Wildlife Refuge Complex on the Eastern Shore of Maryland and Virginia, with […]

(Beyond Pesticides, May 11, 2018) Earlier this month, the U.S. Department of Agriculture (USDA) released its long-awaited proposal for disclosing the presence of genetically engineering (GE) in foods. Much to the disappointment of health, environmental, and consumer advocates, the draft rule appears as an attempt mask or to promote GE products, rather than caution consumers. Concerned individuals can send comments to USDA on the proposed rule through regulations.gov until July 3rd. USDAâs proposal will move forward with wholly insufficient disclosure requirements that the Departmentâs own study had indicated are discriminatory, according to analysts. Rather than use the phrase âgenetically modified,â or âgenetically engineered,â or include the acronyms âGEâ or âGMO,â USDA is using the term âbioengineered.â The symbols proposed by USDA are a happy, smiling sun that would read either âbioengineeredâ or âmay be bioengineered food.â Of course, such a symbol suggests to consumers that these foods are a positive, rather than concerning addition to a food product. However, USDA is also giving the option of simply including the words âbioengineered food,â âcontains a bioengineered food ingredient,â or even leaving that language out and directing consumers to a QR code. A lawsuit by the Center for Food Safety forced USDA […]

(Beyond Pesticides, May 2, 2018) Granola, cereal, and wheat crackers all contain âa fair amountâ of glyphosate, the herbicide in Monsantoâs popular Roundup, according to internal emails from the Food and Drug Administration (FDA). Although the results of these tests have not been formally released, FDA had stated it will be conducting tests for glyphosate in food. Previous reports have detailed the presence of glyphosate, the chemical classified as a âprobable carcinogen,â in a wide range of foods and in peopleâs bodies. Internal emails obtained by The Guardian through a Freedom of Information Act (FOIA) request reveal communication between FDA scientists regarding glyphosate residues in common foods. One email, dated January 2017, detail one scientistâs results from foods taken from his own home. âI have brought wheat crackers, granola cereal and cornmeal from home and thereâs a fair amount in all of them,â FDA chemist Richard Thompson wrote to colleagues in the email last year regarding glyphosate. He further went on to write that broccoli was the only food he had âon handâ that he found to be glyphosate-free. According to The Guardian, another FDA chemist Narong Chamkasem separately found âover-the-toleranceâ levels of glyphosate in corn, detected at 6.5 parts per million, an FDA […]

(Beyond Pesticides, April 10, 2018) Current strategies aimed at managing herbicide resistant weeds in agriculture are not effective and may exacerbate weed problems, according to research published earlier this year by scientists at University of Sheffield in the United Kingdom (UK). While the conventional wisdom in farming, promoted strongly by the chemical industry, is that resistance can be adequately managed by rotating the herbicides used, researchers did not find evidence to support this strategy. In an ode to Occamâs razor, a philosophical theory that hypotheses with the fewest assumptions may be the correct one, researchers found the best method to reduce weed resistance to herbicides was to reduce the overall use of herbicides. Sheffield scientists focused their research on the occurrence of a common weed in the UK called black-grass. This weed was found to occur on 88% of the farmland tested in the study, and has recently been spreading into new areas it had never before colonized. Rob Freckleton, PhD, a population biologist and co-author of the study indicated to Science Daily, “The driver for this spread is evolved herbicide resistance: we found that weeds in fields with higher densities are more resistant to herbicides.â Thus, the more abundant […]

(Beyond Pesticides, April 4, 2018) In late March, the Missouri Department of Agriculture hosted a public hearing to discuss a proposed emergency rule restricting the sale and use of the herbicides dicamba and 2,4-D â which are known for their ability to drift off-site and damage sensitive crops. The emergency rule was introduced to prevent off-label use of specific dicamba or 2,4-D products. Thus far, dicamba is responsible for damaging approximately 325,000 acres of soybeans in the state last year. The proposed rule will stop sales of the herbicides dicamba and 2,4-D between April 15 and October 1 in Missouri. The departmentâs goal is to prevent off-label pesticides from drifting onto neighboring property and damaging other crops. According to the department, if it chooses to pursue an emergency rule, it could become effective as soon as April 1, 2018, and expire 180 days later. The rule also requires registrants to provide a sales record by April 30 for each pesticide sold between October 1 and April 15. A proposed rule will be filed at the same time as an emergency rule to initiate the formal rulemaking process. The draft rule language reads as follows: Pesticides that meet the conditions of this section are […]

(Beyond Pesticides, February 7, 2018) New data from the California monarch butterfly count indicate that the western population of the species is continuing to decline at an alarming rate, with scientists and conservation groups pointing to man-made factors like logging, climate change, and herbicide use on genetically engineered (GE) crop fields as primary drivers. The annual California count of western monarch butterflies stationed volunteers at 262 sites, more than ever before, yet at 200,000 butterflies counted, the numbers nearly matched the lowest level recorded this decade, when only 145,000 butterflies were seen in 2012. The decline of these iconic butterflies demands swift action from lawmakers and regulators to protect their dwindling numbers. Dramatic declines in monarch populations mirror continuing declines in honey bees and other wild pollinator species. Species declines may be even broader than pollinators, affecting all insects in general. Research from Germany recently found that insect abundance declined 75% over the last 30 years, owing the results primarily to agricultural intensification. The western population of monarch butterflies â those found west of the Rocky Mountains â overwinter in coastal California forests. Throughout the warmer months, female butterflies will lay eggs only on milkweed, making these plants critical to […]
