(Beyond Pesticides, January 27, 2015) In  evaluating a farmworker poisoning incident in Washington State last year, a Centers for Disease Control and Prevention (CDC) report identifies “at least three potential occupational hazards in agriculture: off-target pesticide drift, toxicity of some recently marketed pesticides, and a gap in worker notification requirements.” The report recounts the poisoning in  April 2014 of 20 farmworkers at a Washington State cherry farm who were trellising cherry tree branches when a new pesticide mixture being applied to a neighboring pear orchard drifted on to their work site, causing acute illness within minutes. Sixteen farmworkers sought medical treatment for symptoms ranging from headache and eye irritation to gastrointestinal disorders and respiratory problems. Half of the affected workers had symptoms which persisted over two weeks. The workers were not notified of the planned pesticide application at the neighboring orchard. The  CDC report on the incident, authored by Geoffrey M. Calvert, MD (National Institute for Occupational Safety and Health), Luis Rodriguez, and Joanne Bonnar Prado, MPH  (Washington  State Department of Health), cites 31% of acute pesticide related illnesses for farmworkers between 2005 and 2012 occurring as a result of off-target drift from a neighboring farm. In the April incident, […]

(Beyond Pesticides, December 8, 2014) In response to Home Depot’s decision to start requiring all nursery plants that have been treated with neonicotinoids to carry a label to inform customers, at least one nursery supplier has decided to change its management practices. J.Berry Nurseries, a company based out of Grand Saline, Texas, which supplies plants to over 1,000 Home Depot stores throughout Texas, surrounding states and the Midwest, says that since the issue has become publicly recognized for its impacts on bees and other pollinators, it will stop using neonics and start to look at alternative practices. This news provides testament to the power of consumer demand, and along with Beyond Pesticides’ Pollinator-Friendly Seeds and Nursery Directory, should encourage other growers to ditch the neonics in favor of better management practices. “We view it as the labeling of a plant with that tag is potentially creating customers’ perception that that plant should not be purchased,” Jim Berry, the president of J. Berry Nurseries, told Nursery Management Magazine. “Whether it’s a valid assumption or not, perception is reality. So you have to go with that. We certainly want consumers to be attracted to our plants instead of repelled by them.” The […]

(Beyond Pesticides, November 26, 2014) Last week, over 100 scientists from diverse disciplines released a letter citing the growing body of scientific evidence that neonicotinoids and other systemic pesticides harm bees, and called on leaders of President Barack Obama’s Pollinator Health Task Force to quickly take action on pesticides to protect and promote healthy populations of bees and other pollinators. The letter was submitted in response to the recent “listening sessions” hosted by U.S. Environmental Protection Agency (EPA) and the U.S. Department of Agriculture (USDA). These sessions were held by the agencies to  collect public  feedback  on federal efforts on pollinator protection, and the Task Force convened to develop a National Pollinator Health Strategy. In June, the White House issued a Presidential Memorandum directing federal agencies to  join the  Pollinator Health Task Force, led by USDA, to develop pollinator health solutions. The 108 scientists ””whose areas of expertise include entomology, agronomy, ecology, ecotoxicology”” called on Task Force co-chairs, EPA Administrator Gina McCarthy, and USDA Secretary Tom Vilsack, to place a moratorium on the use of neonicotinoid pesticides in the U.S., and increase investment, research and funding for growers to adopt alternatives. In the letter, the scientists note that, “While gaps […]

(Beyond Pesticides, October 31, 2014) Without any mention of the role of pesticides in bee decline, or emphasis on organic practices to help pollinators, Agriculture Secretary Tom Vilsack announced Wednesday that more than $4 million in technical and financial assistance will be provided to help farmers and ranchers in the Midwest improve the health of honey bees. The announcement renews and expands on a $3 million pilot investment last spring to create pollinator-friendly habitat in five Midwestern states. The effort responds to the Presidential Memorandum, which directs USDA to expand the acreage and forage value in its conservation programs. The Memorandum, issued at the close of National Pollinator Week 2014, directed federal agencies to establish a Pollinator Health Task Force, and tasked agency leads at the U.S. Department of Agriculture (USDA) and U.S. Environmental Protection Agency (EPA) to develop a pollinator health strategy within 180 days that supports and fosters pollinator habitat. “The future of America’s food supply depends on honey bees, and this effort is one way USDA is helping improve the health of honey bee populations,” Vilsack said. “Significant progress has been made in understanding the factors that are associated with Colony Collapse Disorder and the overall health […]

(Beyond Pesticides, October 22, 2014) The U.S. Environmental Protection Agency (EPA) has announced a new voluntary Drift Reduction Technology (DRT) program to encourage the use of spray technologies scientifically verified to significantly reduce pesticide drift. But with the recent approval of increased uses of toxic pesticides, such as 2,4-D, and the general lack of compliance with pesticide labels, many believe that this new program may not go far enough to protect non-target sites and vulnerable communities from drift until serious efforts to reduce widespread use of toxic, highly volatile pesticides are undertaken. Pesticide drift is an inevitable consequence of pesticide use, and has been a problem for communities adjacent to agricultural areas and non-target sites for decades. Many pesticide products are released as foliar sprays into the air, or volatilize from surfaces where particles can travel for miles from their application site. This means that on a windy day pesticide residues can drift far distances, affecting  downwind, vulnerable communities, organic farms and other environments. Legal action has been taken against the agency to protect communities from drift, but EPA has consistently failed to meaningfully address concerns. To address issues of drift, EPA’s new program will attempt to reduce drift by […]

(Beyond Pesticides, October 15, 2014) A new study published in Environmental Health Perspectives finds a strong relationship between the use of pesticides and depression in farmers. One specific class of pesticide, organochlorines, was associated with a 90% higher chance of being diagnosed with depression. For fumigants, the increased risk was up to 80 percent. This study echoes the conclusion from an earlier French study which also reported that farmers using pesticides face  a greater risk of developing depression. The study, Pesticide Exposure and Depression among Male Private Pesticide Applicators in the Agricultural Health Study, examines possible associations between pesticide exposure and depression among male private pesticide applicators in the Agricultural Health Study (AHS). Over 21,000 applicators who enrolled in the study in 1993—1997 were followed and examined. The applicators were asked about depression when enrolled in the study and then again around 2010. Previous work with this AHS sample found a higher prevalence of depression among male applicators who reported past pesticide poisoning or use of pesticides from several different classes. However, this study examines specific pesticides, and finds that two types of pesticides, fumigants and organochlorine insecticides are positively correlated with depression and cumulative days of use. Those exposed […]

(Beyond Pesticides, October 14, 2014) Though pollinators only account for about 10% of the production of food crops worldwide, pollinator decline could play a disproportionate role in affecting human health in regions that are already facing food scarcity, according to a new study. Global malnutrition overlaps with pollinator-dependent micronutrient production, published last month in the Proceedings of the Royal Society B. The study  examines regional differences in pollinator dependence of the micronutrient content in crops, revealing a significant overlap between this dependency and the severity of nutrient deficiency. Previous research has underscored the importance of pollinators to agriculture in the U.S., finding that their services are essential to crop yields,  A  May 2013 report by the U.S. Department of Agriculture (USDA)  found that one in three bites of food depends on pollination, mainly by honey bees, and that pollination is valued at $20 to $30 billion annually. For the study, scientists collected data on nutrient contents, pollination dependence and regional agricultural yields for more than 100 of the most common crops grown for global consumption. Combining that data with USDA nutritional information, they were able to determine that three essential nutrients were dependent on pollinators, vitamin A, iron and folate. […]

(Beyond Pesticides, October 6, 2014) Two reports released last week add to the growing concerns surrounding the overuse of antibiotics in livestock and the corresponding public health and safety impacts of increases in antibiotic-resistant bacteria, known as superbugs. Researchers at the University of Texas investigated whether infections of a common and dangerous digestive tract infection, Clostridium difficile (CDI), increased during the period 2001 to 2010. The study, ”˜Deadly diarrhea’ rates nearly doubled in 10 years, examined data from the U.S. National Hospital Discharge Surveys (NHDS), which included 2.2 million CDI discharges. The analysis found that based on these data not only had CDI incidences increased, but they had nearly doubled from 4.5 percent to 8.2 percent. “Several factors may have contributed to the rise in CDI incidence in recent years,” said Kelly Reveles, PharmD, PhD, and lead author on the study. “Antibiotic exposure remains the most important risk factor for CDI.” While overuse of antibiotics in humans is a part of the equation, according to the study, reducing unnecessary use of antibiotics agriculture, including  conventional livestock production, has also been a primary target of concern. Because conventional livestock producers use antibiotics as growth stimulators as well as prophylactic, or subtherapeutic, […]

(Beyond Pesticides, September 12, 2014) A new U.S. Geological Survey (USGS) report finds that levels of pesticides continue to be a concern for aquatic life in many of the Nation’s rivers and streams in agricultural and urban areas. The study, which documents pesticide levels in U.S. waterways for two decades (1992-2011), finds pesticides and their breakdown products in U.S. streams more than 90 percent of the time. Known pesticide water contaminants, such as atrazine, metolachlor, and simazine, continue to be detected in streams more than 50 percent of the time, with fipronil being the pesticide most frequently found at levels of potential concern for aquatic organisms in urban streams. According to the USGS report, “An Overview Comparing Results from Two Decades of Monitoring for Pesticides in the Nation’s Streams and Rivers, 1992—2001 and 2002—2011,” featured in the journal, Environmental Science and Technology and part of the agency’s ongoing National Water-Quality Assessment Program, the proportion of streams with one or more pesticides that exceed an aquatic-life benchmark (or guideline) is similar between the two decades for streams and rivers draining agricultural and mixed-land use areas, but much greater during the 2002-2011 for streams draining urban areas. During both decades, one or […]

(Beyond Pesticides, September 11, 2014) A study of pregnant women living near or working in Costa Rican banana fields shows disturbing levels of the fungicidal component ethylene thiourea (ETU) in the urine samples collected from the women tested. In 72 percent of the 445 women tested, researchers found ETU in urine at levels five times greater than that of the general population. The levels detected in the urine exceed reference doses  ””the numbers set by regulatory agencies, like the U.S. Environmental Protection Agency (EPA), that reflect the maximum acceptable oral dose of a toxic substance. Scientists conducting the study, Aerial Application of Mancozeb and Urinary Ethylene Thiourea (ETU) Concentrations among Pregnant Women in Costa Rica: The Infants’ Environmental Health Study (ISA), focused on ethylene thiourea because it is the main metabolite of the active ingredient found in Mancozeb, a fungicide used in agriculture, professional turf management, and horticulture. The fungicide’s prominent uses on food and feed crops include tree fruits, such as bananas, apples, and pears. It is not just the presence and levels found within the urine that  is troubling. Researchers also discovered that pregnant women who live within 48 meters of banana plantation have on average 45% more […]

(Beyond Pesticides, September 5, 2014) A study published in a scientific journal finds that the U.S. Environmental Protection Agency (EPA) favors the chemical  industry when making determinations on pesticide safety. Under the Federal Insecticide Fungicide and Rodenticide Act (FIFRA), EPA conducts  risk assessments to determine whether a new or existing chemical is eligible for registration or reregistration and therefore able to enter or remain on the market. The study’s conclusions raise serious concerns for both environmental and human health protection because of EPA’s practice of inviting bias and underestimating potential harm. The study, which will be in the October issue of BioScience, highlights the case of atrazine, an herbicide that has been linked to cancer, endocrine disruption, birth defects, and reproductive effects. In their study, Michelle Boone, Ph.D., of Miami University, and her colleagues find that most pesticide toxicity tests used in risk assessments are conducted by pesticide manufacturers themselves. The authors contend that this can result in conflicts of interest. Additionally, strict methodological criteria, such as the types of containers in which exposed specimens are raised, often mean that potentially relevant studies are barred from EPA’s assessment process. The agency reassessed atrazine  based on a sole, manufacturer-funded study, finding […]

(Beyond Pesticides, August 14, 2014) Pesticides are not the first thing to pop into mind when peering into a hot mug of steaming, pale green or murky black tea first thing in the morning. A recent report published by Greenpeace India announced the results of an investigation that tested for pesticide residues in branded tea. The verdict? Nearly 94% of the tea samples tested contained at least one of 34 different pesticides, while over half contained a toxic cocktail of more than 10 different pesticides. The residues found include DDT, which was banned for use in agriculture in India since 1989, and endosulfan, which was banned in 2011 by the Indian Supreme Court. Over half of the 49 samples contained illegal pesticides — either those that are not approved for use in tea cultivation or exceeded recommended limits. These pesticides include ones that have been long banned from agriculture and use in tea cultivation (DDT and triazophos), suspected mutagens and neurotoxicants (monocrotophos), and insecticides associated with the global decline in bee populations (neonicotinoids like thiacloprid and thiamethoxam). The most frequently detected pesticides include thiamethoxam (78%), cypermethrin (73%), acetamiprid (67%), thiacloprid (67%), DDT (67%), deltamethrin (67%), dicofol (61%), imidacloprid (61%), and […]

(Beyond Pesticides, July 23, 2014) New Zealand’s Environmental Protection Authority is stepping up its requirements for a higher level of scientific evidence regarding the safety and effects of neonicotinoids -pesticides linked to bee decline- before considering them for approval. Just last month, the Authority declined an application of thiamethoxam, a neonicotinoid, for use as a seed treatment, citing risks to bees. The decision follows a recent worldwide integrated assessment of research into systemic pesticides that concludes that neonicotinoid insecticides pose a serious risk to birds, honey bees and other pollinators, and a wide range of invertebrates, including earthworms. The international analysis of 800 peer-reviewed scientific reports confirms concerns of beekeepers and environmental groups throughout the world that long-term exposure to systemic pesticides at low, sublethal levels could be harmful to bees and a factor in declining bee populations. While it is unclear what these new stringent requirements are, the Authority, which works with New Zealand’s Beekeepers Association on the issue, already confirmed specific restrictions to products containing neonicotinoids to minimize the risk to insect pollinators. These restrictions include the prohibition of the use of neonicotinoids in areas where bees are foraging, or on plants and trees while they are in […]

(Beyond Pesticides, July 17, 2014) The U.S. Fish and Wildlife Service (FWS) issued an internal memorandum last week that  signals a significant shift in its pesticide-application policies for Pacific Region wildlife refuges: no more neonicotinoids. The memorandum, dated July 9, 2014, states, “The Pacific Region will begin a phased approach to eliminate the use of neonicotinoid insecticides (by any method) to grow agricultural crops for wildlife on National Wildlife Refuge System lands, effectively immediately. By January 2016, Region 1 will no longer use neonicotinoid pesticides in any agricultural activity.” In February 2014, environmental groups, including Beyond Pesticides, filed a legal petition to ban the use of neonicotinoids on wildlife refuges. The new guidelines go on to explain that the change in policy will also affect the transition period through 2016. During that time, refuge managers must exhaust all remedies before application or use of neonicotinoids, including the use of neonicotinoid-treated seeds. Additionally, starting in 2015 all refuge managers must prepare and submit a Pesticide Use Proposal (PUP) in order to apply any neonicotinoids during the transition to the ban. While not a direct response to the petition filed earlier this year calling for a ban of genetically-engineered crops and neonicotinoids […]

(Beyond Pesticides, July 15, 2014) More nutritional antioxidants, far fewer toxic pesticides; those are the results of a comprehensive meta-analysis on organic foods published yesterday in the British Journal of Nutrition.  Led by Carlo Leifort, Ph.D, at England’s Newcastle University, the analysis is a scientific rebuttal to a previous Stanford University review published in 2012, which found that there was little difference between the nutritional content of organic food over conventionally grown produce. Both studies found there to be fewer pesticides in organic products. While Stanford University’s review only looked at 200 studies, Dr. Leifert and his team of researchers expanded the scope of their meta-analysis to 343 studies, and also employed more robust analytic tools by analyzing the standardized mean differences of the data from the various studies. It shows very clearly how you grow your food has an impact,” said Dr. Leifert to The New York Times. “If you buy organic fruits and vegetables, you can be sure you have, on average, a higher amount of antioxidants at the same calorie level.” Antioxidants, compounds such as phenolic acids, flavanones, stilbenes, flavones, flavonols and anthocyanin, have been linked to lower risks of cancer and other diseases. For many, news […]

(Beyond Pesticides, July 10, 2014) In the face of public outcry and protest, chemical-industry giant, Syngenta, has withdrawn its emergency application to allow the use of neonicotinoid pesticides on United Kingdom (UK) oilseed rape crops (known as canola in the U.S.). The application, filed earlier this year in anticipation of the UK canola growing season, claimed that canola farmers would suffer irreparable damage from pests without the use of neonicotinoids that had been banned under a temporary two-year European Union (EU). The EU’s directive that went into effect at the end of 2013 and will continue through 2015 was enacted to protect the severely declining and threatened bee populations  ””a problem  throughout Europe and the world. While many factors contribute to the bee decline, neonicotinoids, a relatively new class of pesticides, have been linked through numerous studies to the significant decline and were determined by the European Food Safety Authority to be a “high acute risk.” Neonicotinoids are often used as a seed coating on agricultural crops as well as in foliar applications, affecting bee and pollinator survival at several different levels. Whereas foliar applications can lead to mass-die offs and acute toxicity, systemic applications to seeds subject bees and […]

(Beyond Pesticides, July 7, 2014) A study led by the U.S. Geological Service (USGS) finds intersex fish in three watersheds of Pennsylvania and shows strong connections between these occurrences and increased pollution in waterways from endocrine-disrupting chemicals. The study, Reproductive Health Indicators of Fish from Pennsylvania Watersheds: Associations with Chemicals of Emerging Concern, examined three species of fish in three separate watersheds of Pennsylvania to assess whether characteristics caused by hormones and hormone-mimicking compounds, such as immature eggs in male fish, were present. In aquatic environments, the presence of these intersex characteristics is widely used as a biomarker for assessing exposure to estrogenic chemicals, as well as anti-androgenic chemicals which inhibit development of male characteristics. Male smallmouth bass from all sites sampled had immature eggs in their testes; prevalence was lowest in the Ohio drainage, intermediate in the Delaware and highest in the Susquehanna. While these findings were disturbing in and of themselves, the study was also able to draw a connection to the increased presence of intersex characteristics and areas of high agricultural use. “The prevalence and severity of the immature eggs in smallmouth bass corresponded with the percent of agricultural land use in the watershed above the collection […]

(Beyond Pesticides, June 26, 2014) Over half of the “bee-friendly” home garden plants sold at garden supply centers such as Home Depot, Lowe’s, and Walmart have been pre-treated with pesticides shown to harm and kill bees, according to a study released yesterday by Friends of the Earth, Beyond Pesticides and allies. The study, Gardeners Beware 2014, shows that 36 out of 71 (51 percent) of garden plant samples purchased at top garden retailers in 18 cities in the United States and Canada contain neonicotinoid (neonic) pesticides — a key contributor to recent bee declines. Some of the flowers contained neonic levels high enough to kill bees outright and concentrations in the flowers’ pollen and nectar are assumed to be comparable. Further, 40% of the positive samples contained two or more neonics. Gardeners Beware 2014 is a larger follow up to a first-of-its-kind pilot study co-released by Friends of the Earth, Beyond Pesticides, and other groups last August. The new study expanded the number of samples and number of locations where plants were purchased, and also assessed the distribution of neonic pesticides between flowers and the rest of the plant. “Our data indicate that many plants sold in nurseries and garden […]

(Beyond Pesticides, June 25, 2014) Following last week’s celebration of “National Pollinator Week” and a presidential memorandum mandating federal action on bees, the first wide-scale scientific analysis has been released that links  two classes of pesticides  to declining bee populations. Twenty-nine scientists representing many disciplines reviewed over 800 peer-reviewed publications  on the impacts of systemic pesticides, and are recommending  more restrictions on neonicotinoid pesticides. This report is the single most comprehensive study of  neonicotinoids ever  undertaken. The “Worldwide Integrated Assessment (WIA)” ”” undertaken by the Task Force on Systemic Pesticides ”” documents significant harms to bees and ecosystems. While some aspects of this report have been broadly acknowledged  before (e.g. risks to honey bees), some, including risks to earthworms, birds and aquatic invertebrates, have not. The analysis focuses not only on impacts to particular  organisms and habitats, but also on  biodiversity and ecosystem impacts, taking a holistic view of pesticide effects. The scientists are calling for new, dramatic restrictions on bee-harming pesticides in the United States and beyond. The report  finds that the current regulatory system has failed to consider the full  range of pesticide effects. “This report should be a final wake up call for American regulators who have […]

(Beyond Pesticides, June 3, 2014) In a letter to the Environmental Protection Agency (EPA) and the U.S. Department of Agriculture, the Center for Food Safety (CFS) challenged EPA’s position that seeds coated with pesticides, commonly neonicotinoid pesticides, are exempt from regulation  under the Federal Insecticide Fungicide and Rodenticide Act (FIFRA). EPA currently is arguing that pesticide-coated seeds are treated articles, exempting them from being regulated as a pesticide and should be regulated by USDA under the Federal Seed Act.   However, CFS argues in its letter that FIFRA precludes EPA from approving language at any stage of the pesticide’s supply chain that allows for exposures likely to adversely affect the environment, and which are not mitigated or investigated by EPA or state agencies. Neonicotinod seed treatments have become increasing common and are linked to the explosion of genetically engineered (GE) crops. At least 94% of the nation’s 92 million acres of corn –greater than the total size of the state of Minnesota, Nebraska, or both Dakotas–  will be treated with one of two neonicotinoids, both manufactured by Bayer. According the letter, CFS believes this inaction by EPA has led state regulators to avoid investigating bee deaths from exposure to dust […]

(Beyond Pesticides, May 21, 2014) In response to recent public concern over the use of bee-killing systemic insecticides in treated nursery plants, Minnesota has just passed labeling legislation, HF 2798, which will inform consumers which plants are bee-friendly. The move follows a commitment by two Minnesota state agencies to study the impact of neonicotinoid pesticides, which ””given mounting research implicating neonicotinoids in bee declines”” beekeepers claim do not go far enough. Although the bill does not address agricultural neonicotinoid use, it is the first of its kind to ensure that nurseries keep tabs on the insecticides used on garden plants. Under the bill passed by Minnesota’s House and Senate last week, plants may not be labeled as beneficial to pollinators if they have been treated with detectible levels of systemic insecticides. Specifically, “A person may not label or advertise an annual plant, bedding plant, or other plant, plant material, or nursery stock as beneficial to pollinators if the annual plant, bedding plant, plant material, or nursery stock has been treated with and has a detectable level of systemic insecticide that: (1) has a pollinator protection box on the label; or (2) has a pollinator, bee, or honey bee precautionary statement […]

(Beyond Pesticides, May 12, 2014) A study published in the Bulletin of Insectology substantially undercuts chemical industry arguments that neonicotinoid pesticides are not the primary contributing factor  in Colony Collapse Disorder (CCD). The results find that  hives exposed to low doses of two neonicotinoid pesticides””imidacloprid and clothianidin””do not recover from over winter losses from which  control hives quickly rebound. Researchers also discount other possible causes of CCD commonly touted by industry like diet, parasites, and pathogens. The study adds to the already expansive literature that  clearly links sublethal exposure neonicotinoid pesticides to rapid bee declines nationwide. The study, Sub-lethal exposure to neonicotinoids impaired honey bees winterization before proceeding to colony collapse disorder, was conducted in central Massachusetts during the 2012-2013 winter at three different locations with six bee colonies in each location. A third of the colonies were exposed to low doses of the pesticide imidacloprid, while another third were exposed to the pesticide clothianidin, both neonicotinoids, and the remainders were not treated. At each apiary the colonies were separated into two groups in which honey bees were fed with either sucrose water or high-fructose corn syrup (HFCS) over the study period. During the fall and winter seasons, researchers found […]

(Beyond Pesticides, May 8, 2014) – Two citizen groups have taken the initial step toward debunking chemical-industry claims that glyphosate, the world’s most widely-used herbicide, does not bioaccumulate or metabolize in humans. The pilot study, conducted by Moms Across America and Sustainable Pulse, looked at ten breast-milk samples and 35 urine samples from across America and 21 drinking water samples. The groups commissioned Microbe Inotech Labs to conduct the analysis, and what they found raises some serious questions about the prevalence and persistence of glyphosate. In breast milk, three of the ten samples tested reveal high levels of glyphosate, meaning that the amount of glyphosate found  is between 76 ug/l to 166 ug/l. The highest glyphosate level detected in a mother is from Florida (166 ug/l) and the other two mothers with “positive” results are from Virginia (76 ug/l) and Oregon (99 ug/l). While these levels fall under the U.S. Environmental Protection Agency (EPA) drinking water maximum contaminant level (MCL) of 700 ug/l, across the pond in Europe this range of exposure is 1,000 higher than what is deemed safe. From the 35 urine samples received from across the U.S., 13 samples are above the minimum detectable level. The three […]
