(Beyond Pesticides, November 30, 2018) A study published this month in Science of the Total Environment reveals numerous pesticide residues persisting in soil, harming the viability of agricultural lands and increasing risk of off-site contamination. Funded by the Horizon 2020 programme of the European Commission, researchers from the European Diverfarming project at the University of Wageningen in the Netherlands suggest nations urgently reevaluate conventional land use and inputs including water, energy, fertilizers, machinery and pesticides. Researchers decrying the lack of soil protection policies endeavored to determine which pesticides had the highest soil persistence and toxicity to non-target species. Three hundred seventeen surface soil samples were analyzed from 11 European countries. Selected countries were those with the largest amounts of active agricultural land, characterizing six distinct cropping systems. Sampled soils purposefully represented different soil properties and were taken from crops with the highest pesticide use per hectare. Samples were then analyzed for the concentration of 76 pesticide residues. These 76 pesticides were selected as being most often applied on conventional crops. Eighty-three percent of samples contained varying degrees of pesticide residues, with 25 percent showing one pesticide residue and 58 percent showing mixtures of two or more. Only 17 percent of […]

(Beyond Pesticides, November 29, 2018) The British Cayman Islands will no longer fund the release of genetically engineered (GE) mosquitoes, as reports indicate that the program failed to achieve its intended goals.  The government is formally terminating its contract with the UK-based company Oxitec, which marketed GE mosquitoes as a sort of silver bullet for the management of diseases such as Zika, yellow fever, malaria, and dengue. Advocates opposed to the GE mosquito program are continuing to encourage a focus on education and source reduction as the best method to address mosquito-borne diseases. Oxitec first began introducing its line of GE mosquitoes earlier in the decade, at a variety of locations including India, Brazil, Malaysia, and the Florida Keys. Public opposition to the release has been consistently strong. In the Florida Keys, over 230,000 people signed a change.org petition opposing the release. In the Cayman Islands, residents launched a number of lawsuits. In each instance the company was granted free reign to initiate its program. GE mosquitoes aim to ‘gene drive’ mosquito populations out of existence, a process intended to propagate a particular set of genes in a species. The company developed GE mosquitoes in a laboratory, injecting a gene […]

(Beyond Pesticides, November 28, 2018) Recent research out of Harvard University and published in the journal Science has demonstrated some of the mechanisms through which exposures to neonicotinoid pesticides harm bumblebee populations. The study found that exposure to imidacloprid, a neonicotinoid — the most widely used category of pesticides worldwide — directly impacts social behaviors in bumblebees. These behaviors have serious effects on the functioning and viability of bee colonies. In the research experiment, worker bees exposed to imidacloprid exhibited reduced general and nurturant activity, and a tendency to locate themselves at the periphery of the nest. The study noted decreased caretaking and nursing behaviors, which in turn harms productivity and thermal regulation in the colony. These tasks are important to colony development; impaired thermoregulation negatively affected the bees’ typical construction of an insulating wax canopy for the nest, and poor caretaking can affect brood growth. Investigators noted that, “Neonicotinoids induce widespread disruption of within-nest worker behavior that may conribute to impaired growth. . . . These changes in behavior acted together to decrease colony viability, even when exposure was nonlethal.” The authors also observed that many of these dysregulated behaviors were more pronounced at night than during sunlight hours, and […]

(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 Bayer’s 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 agency’s 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 Bayer’s Monsanto in conducting field trials this past summer, but found high volatility and drift of the company’s 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 26, 2018) Organic consumers expect that the organic products they buy are grown without toxic chemical inputs. However, oil and gas wastewater (including fracking wastewater) is currently used to irrigate crops. Among the chemicals known to be present in oil and gas wastewater are heavy metals and other chemicals with carcinogenic, reproductive, developmental, endocrine-disrupting, and other toxic effects. When the Organic Foods Production Act (OFPA) was passed, and regulations adopted, there was no agricultural use of oil and gas wastewater, so the regulations did not address these hazards.  Tell USDA to Outlaw Fracking Wastewater in Organic Production!  The Cornucopia Institute has filed a petition for rulemaking, asking that oil and gas wastewater be ruled a prohibited substance in organic production. This issue should be put on the work agenda of the National Organic Standards Board (NOSB), which advises the Secretary about issues concerning NOP. The petition from the Cornucopia Institute contains information that will serve as support for the work agenda item. Over the past several years, the NOSB has received many comments requesting them to address this issue Among the comments have been suggestions for guidance to farmers faced with contamination from oil and gas activities. The […]

(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 21, 2018) A study published last month in the Journal of Apicultural Research finds significant numbers of U.S. honey bees at risk after exposure to hazardous synthetic pesticides intended to control mosquitoes. With many beekeepers rarely given warning of insecticide spraying, researchers say the risk of losing colonies could increase. Advocates say fear of Zika and other mosquito-borne illnesses could result in counterproductive and reactionary insecticide spraying that will add further stress to managed and native pollinators already undergoing significant declines. Researchers aimed to determine whether neighboring honey bee colonies could be similarly affected by aerial insecticide spraying. To calculate the percentage of colonies that could be affected, density of honey bee colonies by county was compared with projections of conditions thought to be prone to regional Zika virus outbreaks. Researchers found 13 percent of U.S. beekeepers at risk of losing colonies from Zika spraying. In addition, it was determined that many regions of the U.S. best suited for beekeeping are also those with favorable conditions for Zika-prone mosquitoes to proliferate. These regions include the southeast, the Gulf Coast, and California’s Central Valley. “[Considering] all the threats facing bees,” says study lead author Lewis Bartlett of the […]

(Beyond Pesticides, November 20, 2018) Scientific conclusions used to support the registration of the insecticide chlorpyrifos were flawed and omitted key health impacts, according to a fresh analysis of the original data by a team of independent scientists from northern Europe and the U.S. This re-review not only casts further doubt on the safety of the neurotoxic chlorpyrifos, it highlights a major flaw within federal pesticide regulation that allows pesticide producers to submit their own safety evaluations to the U.S. Environmental Protection Agency without public oversight. “One conclusion we draw is that there is a risk that the results of industry-funded toxicity tests are not reported correctly,” says co-author Axel Mie, PhD. “This makes it difficult for the authorities to evaluate the pesticides in a safe and valid way.” In both the U.S. and European Union, pesticide producers contract with laboratories to perform required safety tests of active ingredients they hope to register for use. While these studies are generally considered ‘confidential business information’ and not available to the public, using Swedish freedom of information laws, researchers were able to obtain two key studies relating to the developmental neurotoxicity of chlorpyrifos. Although not disclosed within the study, it is well […]

(Beyond Pesticides, November 19, 2018) The Organic Foods Production Act (OFPA) requires organic milk and dairy products labeled as organic to come from dairy cows continuously managed as organic from the last third of gestation. Because of the short supply of organic dairy breeder stock when the law was passed in 1990, a one-time conversion of conventional dairy cows to organic was allowed, as long as they are managed organically. Please urge the Secretary of Agriculture to issue a final rule for Origin of Organic Livestock, as urged by the NOSB. Unfortunately, the National Organic Program (NOP) allowed two interpretations of this provision, turning the provision into a loophole that has allowed some large dairy operations to circumvent the last third of gestation requirement altogether, and bringing conventionally managed animals into their operations on a continuous basis. In 2015, USDA proposed an Origin of Livestock rule to clarify that section of the law and ensure consistent enforcement of the standards, but appears to have no plans to finalize the rule. In its October 2018 meeting, the National Organic Standards Board (NOSB) recognized the unfairness that allows large organic dairies to profit at the expense of smaller dairies who follow the spirit […]

(Beyond Pesticides, November 16, 2018) Pesticides and biocides used to control bacterial infections in humans and weeds and pests in agriculture are surpassing ‘planetary boundaries’ within which human civilization can continue to rely on these biocides, according to a review by an international team of scientists working on the Living with Resistance project. While the study reinforces the role of susceptible populations in managing resistance, it fails to distinguish essential differences between antibiotic resistance and resistance to pesticides that is identified by Beyond Pesticides. The study focuses on six different forms of resistance. Researchers looked at antibiotic resistance in gram negative bacteria (such as E. coli, P. aeruginosa, Salmonella) and gram positive bacteria (such as S. aureus, Clostridium) separately, due to their divergent resistance mechanisms. Pesticide resistance was divided among herbicides in general, herbicide resistant crops, insecticides in general, and genetically engineered (GE) crops that produce their own insecticide. Resistance to antibiotics and pesticides are similar in that they are both evolved responses to substances toxic to the organism. However, lumping them together in evaluating their importance to human health and survival does not recognize important differences in context. “Without new approaches, going to hospital in the future will increasingly become […]

(Beyond Pesticides, November 15, 2018) Neonicotinoids are widely known for their link to declining pollinator populations, but new research finds that the ill effects of these chemicals also extends to amphibian populations. In a study published late last month, scientists from the National Wildlife Research Center in Ottawa, Canada found that chronic exposure to real-world levels of the neonicotinoid imidacloprid limits the ability of juvenile wood frogs to escape a predator attack. This research adds additional evidence that neonicotinoids are harming aquatic food chains, and reinforces calls for U.S. regulators to follow the science and adequately restrict these toxic pesticides. Researchers investigated the impact of neonicotinoids on the post-tadpole life stage of wood frogs, which has been identified as critical to sustaining viable populations of the species. Rather than determine acute impacts that assess how lethal a pesticide is, scientists opted to observe how wood frog behavior changes as a result of chronic, real-world exposure scenarios. In particular, scientists sought to figure out whether exposure resulted in an altered behavioral response to the presence of a predator. As tadpoles, wood frogs were chronically exposed to real world levels of imidacloprid (1, 10, and 100 micrograms/liter), while others were left unexposed […]

(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 York’s 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, November 9, 2018) A Tunisian study (published in January 2018) on the effects in pre-pubertal mice of exposure to malathion — an organophosphate pesticide first registered for use in the U.S. in 1956 — demonstrates significant distortion of liver and kidney biochemistry and function in the animals. Deleterious effects include compromise of feeding ability, metabolism performance, neurologic deficits, reduction of overall body weight, and simultaneous increases in the weights of livers and kidneys, with structural anomalies and lesions in those organs. Organophosphates (OPs) have raised alarm bells for years. Some, such as chlorpyrifos and diazinon, have had their registrations cancelled for household uses because of the extreme health risks to children, but agricultural, golf course, and “public health” (mosquito control) uses remain commercially available and in use. Recently, Beyond Pesticides reported on research whose investigators support — and called publicly for — a worldwide ban on the compounds because of the serious health and environmental risks they pose, particularly for children. Beyond Pesticides has written extensively on OP pesticides, including malathion and chlorpyrifos. Both are used widely in agriculture. Chlorpyrifos has been the subject of quite a ping-pong match in recent years: a scheduled ban by the Environmental Protection […]

(Beyond Pesticides, November 8, 2018) Two months after publishing its first series of tests, part two of an Environmental Working Group (EWG) study finds residues of Roundup’s active ingredient, glyphosate, in all General Mills’ Cheerios and PepsiCo’s Quaker Oats products sampled. Health advocates are expressing concern about the consequences of chronic glyphosate exposure, and say U.S. federal agencies must limit the herbicide’s use on oat-based breakfast foods regularly marketed to children. In addition, organic itself is under threat, as chemical-intensive management practices undermine the future of the growing organic movement. In this second round of testing, EWG scientists purchased products around San Francisco and Washington DC. 28 samples of conventional and 16 samples of organic oat products were collected. Approximately 300 grams of each General Mills and PepsiCo product were packaged and shipped to Anresco Laboratories, in San Francisco. Detected glyphosate residues were compared to EWG’s own health benchmark of 160 parts per billion (ppb). This benchmark is based on risks of lifetime exposure and what EWG scientists consider allowable and protective of children’s health with an adequate margin of safety.  EWG’s results detected glyphosate residues in all 28 samples of conventionally grown oat products. The vast majority (all but two) […]

(Beyond Pesticides, November 7, 2018) Brazil’s rapid industrialization of its agricultural sector may be coming at the cost of resident health, according to a new study published in Chemosphere by an international team of scientists. The researchers link the rise in the country’s pesticide use since the turn of the century to significant increases in colon cancer, particularly in the country’s most intensive agricultural southern regions. With the recent election of far right president Jair Bolsonaro, who has supported policies that would loosen Brazil’s pesticide regulations, advocates are concerned the county’s farming industry is moving in an unsustainable direction. Researchers note that as Brazil’s agriculture industry has grown over the last two decades, it has become the world’s leading consumer of pesticides. In the year 2000, roughly 160 million tons of pesticides were used in the country. By 2012, that number reached nearly 500 million tons. Scientists compared pesticides sold to standard mortality rates (SMR) in each Brazilian state. SMR measures mortality by comparing observed mortality to expected mortality when adjusting for age and gender. A rate above one indicates that there is excessive mortality. Despite improvements in detection and treatment, colon cancer deaths recorded in the country increased from […]

(Beyond Pesticides, November 6, 2018) Scientists working for USDA’s Agricultural Research Service in Lincoln, Nebraska have discovered natural compounds derived from coconut oil that are more effective than DEET at repelling mosquitoes, ticks, biting flies, bed bugs and other insects. Given the long-lasting efficacy of the compounds researchers tested, commercialization could make the regular use of toxic insect repellents, like DEET, obsolete. Advocates are praising USDA researchers for the results, indicating that this is exactly the type of research government agencies should be funding and promoting. It is important to note that USDA scientists did not find coconut oil itself to be an effective repellent. Lab equipment was used to analyze and isolate medium chain fatty acids within coconut oil for their repellent properties. Scientists zeroed in on a blend of C8 (caprylic acid), C10 (capric acid), and C12 (lauric acid) fatty acids as the most effective repellent mixture. Individually, only C12 exhibited anywhere near the same efficacy as the specific blend identified. The study indicates that more research is needed to understand why coconut oil itself was ineffective, and how the synergy between the fatty acid combinations resulted in such effective repellency. To verify their hypothesis on the efficacy […]

(Beyond Pesticides, November 2, 2018) A group of leading toxics experts, who published a paper in the journal PLOS Medicine on their research on organophosphate exposure during pregnancy and impacts on child development, are calling for a ban on organophosphate pesticides. The study evaluates current science on the risks of this class of compounds, produced by Corteva Agriscience (formerly Dow AgroSciences); its conclusions warn of the multitude of dangers of organophosphates for children, and makes recommendations for addressing these risks. The experts conclude that: (1) widespread use of organophosphate (OP) pesticides to control insects has resulted in ubiquitous human exposures; (2) acute exposures to OPs is responsible for poisonings and deaths, particularly in developing countries; and (3) evidence demonstrates that prenatal exposures, even at low levels, put children at risk for cognitive and behavioral deficits, and for neurodevelopmental disorders. Among the authors’ recommendations are these: Governments and subsidiary agencies, including the Environmental Protection Agency (EPA), should phase out chlorpyrifos and other organophosphate pesticides; ban non-agricultural uses of OP pesticides (including in household products); monitor watersheds and drinking water sources of human exposure; promote the use of integrated pest management (IPM) through incentives and training; and establish pesticide use and illness reporting […]

(Beyond Pesticides, October 31, 2018) Residents in the town of Great Barrington, MA are concerned about the health effects that could result from creosote-coated railroad ties stored in their neighborhood. According to a report in the Berkshire Eagle, soon after the Massachusetts Department of Transportation (MDOT) parked a load of railroad ties along tracks that cut through a neighborhood, community members began to complain about the smell. Creosote is a mixture of thousands of different chemical compounds. Derived mainly from coal tar and regulated as a pesticide by the U.S. Environment Protection Agency (EPA), the material represents a significant hazard that puts people and the environment in danger, and can be readily replaced by safer, alternative materials. “I would want to roll up my windows immediately,” Beth Rose told the Berkshire Eagle. Another Great Barrington resident, Jeanne Bachetti, told the paper, “I started to smell them right after they moved [them] in there. Sometimes we get a propane smell from [nearby] AmeriGas, so I couldn’t tell. Then it dawned on me — that’s not gas.” MDOT is currently in the process of a project to upgrade roughly 40 miles of freight line, and is using 60,000 railroad ties as part […]

(Beyond Pesticides, October 30, 2018) The conclusion of a recent population-based cohort study of 68,946 French adults brings promising, though perhaps predictable, news. Greater consumption of organic food — as opposed to food produced conventionally, with use of pesticides and synthetic fertilizers — is associated with a reduction in overall cancer risk, and reduced risk of specific cancers, namely, postmenopausal breast cancer and lymphomas. The NutriNet-Santé Prospective Cohort Study was published on October 22 in the journal JAMA Internal Medicine. It is important to remember that correlation is not causation; but the findings were strong enough that researchers concluded that more research is not only warranted, but also, could “identify which specific factors are responsible for potential protective effects of organic food consumption on cancer risk.” The project tracked subjects — who were 78% female and 44.2 years old, on average — for 4.5 years. Those subjects reported the frequency of their consumption of 16 organic food products as “never, occasionally, or most of the time.” Those included: fruits, vegetables, soy-based products, dairy products, meat and fish, eggs, grains, legumes, breads, cereals, flour, vegetable oils, condiments, ready-to-eat meals, cookies, chocolate, sugar, marmalade, dietary supplements, and some beverages (coffee, teas, and wine).

(Beyond Pesticides, October 29, 2018) Protect the integrity of the organic standard setting process that determines whether a synthetic substance will be allowed in food labeled organic. Help stop an attack on the meaning of the organic label in the Farm Bill, which may be voted out of conference committee by the end of November. By changing the substance review process, a provision will open the floodgates to allowed synthetic chemicals in organic production, handling, and processing under the Organic Foods Production Act (OFPA). OFPA incorporates values and principles that build and regenerate soil, protect pollinators and biodiversity, eliminate toxic pesticide use, and contains a default provision that strictly limits synthetic chemicals in certified organic products. This will all change with the Farm bill amendment. Ask your U.S. Representative and Senators to tell Farm Bill conferees to reject Section 10104(e) National Organic Standards Board in the Senate Farm Bill (S.3042), a provision that will increase the use of synthetic substances in organic food production. OFPA incorporates language that ensures that the process for allowing synthetic chemicals in organic production, handling, and processing is very rigorous. This meets a public expectation that food labeled organic is subject to a higher degree of […]

(Beyond Pesticides, October 26, 2018) California Superior Court Judge Suzanne Bolanos is upholding a jury’s verdict that exposure to the herbicide glyphosate caused school groundkeeper Dewayne Johnson to develop cancer. The ruling comes after concern that Judge Bolanos would intervene and overturn the entire monetary award to Mr. Johnson. However, in her final ruling, the Judge decided only to reduce the punitive damages to the same amount the jury awarded in compensatory damages, $39 million. This ruling reduced the total amount awarded to Mr. Johnson from $289 million to $78 million. While attorneys for Mr. Johnson are disappointed in the reduction, they are pleased that the judge did not take further action. “Although we believe a reduction in punitive damages was unwarranted and we are weighing the options, we are pleased the court did not disturb the verdict,” Diana McKinley, Mr. Johnson’s spokeswoman, told the Associated Press (AP). Bayer, which finalized its merger with Monsanto earlier this year, is vowing to continue its nationwide defense against the over 8,000 cases the company inherited from its former rival currently working their way through the courts. A tentative ruling from Judge Bolanos earlier this month indicated that she thought the jury had […]
