Local Restaurants Launch Campaign to Protect Pollinators during National Pollinator Week

(Beyond Pesticides, June 14, 2016) To celebrate National Pollinator Week, June 20-26, 2016, several Washington, DC restaurants have teamed up with Beyond Pesticides and the Center for Food Safety to launch a campaign, “Made by Pollinators,” to protect pollinators suffering steep declines. With one out of every three bites of food reliant on bees, the participating restaurants’ patrons will be treated to a special menu featuring pollinator-friendly food and provided with information on what they can do to help pollinators. The restaurants hope to increase public awareness on the importance of pollinators and steps that can be taken to reverse the decline. Participating  restaurants include Busboys and Poets, Founding Farmers, Lavagna, the Tabard Inn and Restaurant Nora. Of the 100 crop varieties that provide 90% of the world’s food, 71 are pollinated by bees. Honey bees alone pollinate 95 kinds of fruits, nuts and vegetables, such as apples, avocados, almonds, and cranberries. The value of pollination services to U.S. agriculture alone amounts to nearly $30 billion and about 80% of flowering plants require animal pollination. A recent government survey reports that U.S. beekeepers lost 44 percent of their colonies between spring 2015 and 2016 —the second highest loss to date. […]

Glyphosate Approval in EU Up in the Air

(Beyond Pesticides, June 10, 2016) A proposal for a temporary ‘technical extension’ of the EU approval of the herbicide glyphosate failed to secure the support of a majority of EU governments at a meeting of the EU standing committee on plants, animals, food and feed on Monday. This action may force the withdrawal of the herbicide, widely sold as Monsanto’s Roundup, from shelves if no decision is reached by the end of the month, when its license expires. After a proposal to renew the license for glyphosate for up to 15 years failed to win support in two meetings earlier this year, the EU executive offered a limited 12 to 18 month extension to allow time for further scientific study. Yet, despite this compromise, the proposal failed to win the support of member states representing at least 65% of the EU’s population, which is needed for adoption, an EU official told The Guardian. Seven member states abstained from Monday’s vote, 20 backed the proposal and one voted against, a German environment ministry spokeswoman said. According to the news source, Germany was among those that abstained from Monday’s vote. Of note is that Bayer, the German chemical company, recently offered to […]

Public Comment Needed on EPA’s Plans To Allow Bee-Toxic Sulfoxaflor despite Elevated Bee Losses

(Beyond Pesticides, June 3, 2016) Despite recent reports of continuing bee losses across the U.S., the U.S. Environmental Protection Agency (EPA) has announced plans to reevaluate the use of the bee-toxic insecticide sulfoxaflor, and is proposing an amended registration. Sulfoxaflor’s initial 2013 registration was challenged by beekeepers and subsequently vacated by the Ninth Circuit Court of Appeals due to overwhelming risks to bees and EPA’s inadequate review of the data. Last September, the  Ninth Circuit Court of Appeals unequivocally rejected  EPA’s registration of sulfoxaflor. The Court concluded that EPA violated federal law when it approved sulfoxaflor without reliable studies regarding the impact that the insecticide may  have on honey bee colonies. The Court vacated EPA’s unconditional registration of the chemical, meaning that sulfoxaflor could no longer be used in the U.S. This decision was in response to a suit filed by beekeepers challenging EPA’s initial registration of sulfoxaflor, which cited the insecticide’s threat to bees and beekeeping. The case:  Pollinator Stewardship Council, American Honey Producers Association, National Honey Bee Advisory Board, American Beekeeping Federation, Thomas Smith, Bret Adee, Jeff Anderson v. U.S. EPA  (9th Circuit U.S. Court of Appeals,”¯No. 13-7234) According to the court decision, EPA skirted its own regulations […]

Save the Date: National Pollinator Week Set for June 20-26, 2016

(Beyond Pesticides June 2, 2016) United States Department of Agriculture (USDA) Secretary Tom Vilsack recently released a Proclamation for National Pollinator Week, which is set to take place from June 20-26, 2016. National Pollinator Week began ten years ago when the U.S. Senate unanimously approved the designation of a week in June to address the urgent issue of declining pollinator populations. Pollinator week has since grown to be an international celebration of the valuable ecosystem services provided by bees, birds, butterflies, bats and all other pollinator species. While much remains to be done to combat contributing factors to pollinator declines, such as the use of neonicotinoid pesticides and disappearing pollinator habitat, National Pollinator Week is a chance to reflect and celebrate the achievements of the past year, while simultaneously raising awareness of the important role pollinators play in our daily lives. This year, to help increase education and bring awareness to the issue of pollinator declines, Beyond Pesticides and the Center for Food Safety are teaming up with several Washington, DC area restaurants to launch a “Made by Pollinators” campaign. Participating  restaurants, which include Founding Farmers, Lavagna, Tabard Inn and Restaurant Nora, will  educate the public on the importance of […]

Study Finds Honey Bees Frequently Collect Contaminated Pollen from Non-Crop Plants

(Beyond Pesticides, June 1, 2016) A study  by researchers at Purdue University has concluded  that honey bees collect most of their pollen from non-crop plants that are frequently contaminated with agricultural and urban pesticides. The researchers found this to be true even in places where croplands dominate the area.  The study, which detected neonicotinoids, pyrethroids, fungicides, and others, highlights the large number of toxic pesticides to which bees are exposed to in the environment. Researchers collected pollen from Indiana honey bee hives at three sites over 16 weeks. The hives were placed in a variety of settings, such as an open meadow with wildflowers, woody shrubs and trees present (non-agricultural), the border of a corn field that was treated with the neonicotinoid clothianidin and three fungicides, and the border of a non-treated corn field. The pollen samples that were collected by the bees represented up to 30 plant families and contained residues from pesticides spanning nine chemical classes. The researchers found 29 pesticides in pollen from the meadow site, 29 pesticides in pollen from the treated cornfield, and 31 pesticides in pollen from the untreated cornfield. The most common chemical products found in pollen from each site were fungicides and […]

Maryland Residents Asked to Urge Governor to Sign Pollinator Protection Act, Under Threat of Veto this Week

(Beyond Pesticides, May 26, 2015) Maryland’s historic Pollinator Protection Act, (SB 198 and HB 211) may be in danger. Last month, lawmakers approved the bill by a 98-39 vote in the Maryland House of Delegates, however it faces the possibility of a veto by Governor Larry Hogan (R). While the governor’s office says that the bill is currently under review, according to local news source WBAL, the governor is prepared to veto the bill, which he has until tomorrow, Friday, May 27, to do. If the governor does veto the bill, Maryland’s Pollinator Protection Act will go back to the legislature for an override vote, which will take place in early 2017. Meanwhile, beekeepers continue to lose their bees at unprecedented rates. Last week, we reported results of 2015-16 Colony Loss Survey, which show no sign that the crisis of abating. According to the survey, beekeepers lost 28.1% of their colonies over this past winter, and a total of 44% of their colonies over the last year. This marks the second year in a row that summer declines (28.1%) were on par with declines experienced during winter. WBAL reports that the governor is likely to veto the bill because of […]

A Decade into the Pollinator Crisis, Unsustainable Bee Losses Continue

(Beyond Pesticides, May 17, 2016) It was 10 years ago that commercial beekeepers first reported widespread, unsustainable winter losses of their honey bee colonies. A decade after the alarm was first sounded on pollinator declines, results of 2015-16 Colony Loss Survey show no sign the crisis of abating. According to the Bee Informed Partnership survey, beekeepers lost 28.1% of their colonies over this past winter, and a total of 44% of their colonies over the last year. This marks the second year in a row that summer declines (28.1%) were on par with declines experienced during winter. Beekeepers factor in that a small percentage, <15% of their colonies, will be lost each winter, but do not expect to lose colonies during the summer, when there is amble forage and nectar for bees. The costs beekeepers must incur to keep their hives alive continue to increase. More time and money is spent to maintain their hives, yet losses continue to be staggering ”” and unsustainable. As colony collapse disorder (CCD), the cryptic loss of honey bee colonies with no sign of dead bees in or around the hive, has faded from public discussion, concerns over pollinator declines in general, from bees […]

Macalester College Signs Resolution to ‘Bee Protective”

(Beyond Pesticides, May 11, 2016) Another campus, Macalester College in St. Paul, Minnesota has pledged to become a designated BEE Protective campus. This recognition comes from Beyond Pesticides’ and Center for Food Safety’s BEE Protective Campaign, which aims to protect bees and other pollinators from harmful pesticides like neonicotinoids. As part of its  commitment, Macalester College will  no longer use neonicotinoids on its  campus grounds. Neonicotinoids are a class of pesticides known to have severe impacts on bee populations. Macalester is now one of several campuses around the country that have pledged to protect pollinators and move away from using harmful pesticides that are toxic to these beneficial creatures. Just last month,  Antioch College in Yellow Springs, Ohio pledged to become a BEE Protective campus. In addition to these campuses, several local communities and states are also taking a stand for pollinators by passing policies that restrict the use of bee-toxic pesticides. For more on how your campus or student group can support pollinators and become BEE Protective, visit the BEE Protective Ambassadors webpage. “Macalester’s new resolution to help protect pollinators fits well with our Sustainability Plan and Sustainable Landscaping Master Plan. I’m glad that our college has this opportunity […]

EPA Finds Atrazine Threatens Ecological Health

(Beyond Pesticides, May 10, 2016) Following an apparent accidental release of documents relating to the safety of the herbicide glyphosate, late last month the U.S. Environmental Protection Agency (EPA) also released and then retracted a preliminary ecological risk assessment of another toxic herbicide, atrazine. Under federal law, every pesticide registered in the United States is required to undergo a 15-year registration review to analyze human health and environmental impacts and determine whether the chemical’s use should continue another 15 years. The last decade and a half have seen plethora of studies underscoring that atrazine is harmful to human health, and poses unreasonable adverse risks to ecological health, despite attempts by its major manufacturer, Syngenta, to silence and discredit its critics. EPA’s preliminary ecological risk assessment finds that for current uses at prescribed label rates, atrazine may pose a chronic risk to fish, amphibians, and aquatic vertebrate animals. Where use is heavy, the agency indicates that chronic exposure through built-up concentrations in waterways is likely to adversely impact aquatic plant communities.  Levels of concern, a wonky equation that EPA produces to measure risk, were exceeded for birds by 22x, fish by 62x, and mammals by 198x. Even reduced label rates were […]

Connecticut Legislature Votes Unanimously to Adopt Pollinator Protections

(Beyond Pesticides, May 3, 2016) In a bipartisan victory for bees, last week the Connecticut House of Representatives unanimously (147-0) passed a wide-ranging bill aimed at protecting declining pollinator populations within the state from toxic neonicotinoid (neonic) pesticides. Bill No. 231, An Act Concerning Pollinator Health, was also passed unanimously (36-0) through the Connecticut State Senate on April 21, and now goes to Governor Dannel P Malloy for his signature. Earlier in April, both houses of the Maryland legislature passed the Maryland Pollinator Protection Act, which is currently awaiting action by Governor Larry Hogan (R). Connecticut’s bill addresses a broad range of concerns relating to pollinator health, from pesticides to parasites and habitat remediation, within both residential and agricultural settings. In summary, the bill does the following: Prohibits applying neonicotinoid insecticide (a) to linden or basswood trees or (b) labeled for treating plants, to any plants when such plant bears   blossoms; Bee health experts identified the application of systemic neonicotinoids to Tilia trees as a significant concern for pollinator health after a spate of massive bee-kill incidents on the west coast. In June 2013, over 50,000 bumblebees were killed after a neonic was applied to a linden trees in […]

Study Finds Neonicotinoids Cause Compound-Specific Harm to Bumblebees

(Beyond Pesticides, May 2, 2016) A study published online last week has examined the effects of three neonicotinoids (neonics) on bumblebee colonies, from live bee kills to changed sex ratios. Neonics have been widely cited as contributing to  the demise of both managed and wild bee and pollinator populations. They can cause  changes in bee reproduction, navigation, foraging, and even the suppression of bee immune systems. The study, published in Scientific Reports, looked at field-relevant levels (2.5 parts per billion) of imidacloprid, thiamethoxam, and clothianidin, and found compound-specific effects at all levels, including within individual bee cells, individual bees, and whole colonies in semi-field conditions. Given the limitations of laboratory studies and field studies, researchers conducted a semi-field study to try to recreate and represent real world exposure patterns. The neonics were provided to the bees as an optional supply of sugar syrup, but were free to forage and did need to gather pollen in order to grow and raise offspring. Researchers found that imidacloprid and clothianidin displayed abilities to affect neuronal Kenyon cells, which help with learning, memory and multisensory integration. At the whole colony level, thiamethoxam altered the sex ratio, leaving more males than females. Both imidacloprid and […]

Antioch College and UMD Pledge to Protect Pollinators

(Beyond Pesticides, April 28, 2016) This week, Antioch College in Yellow Springs, Ohio,  became the third university to become a neonicotinoid-free campus.  Antioch College gains recognition from the Beyond Pesticides’ and Center for Food Safety’s  BEE Protective  Campaign, which seeks to protect honey bees and other pollinators from harmful pesticides. Signing the  BEE Protective  resolution, Antioch signaled its continued commitment to using neonicotinoid-free insecticides on campus, making them one of the leading higher education institutions committed to the protection of pollinator species. In addition to joining the Bee Protective Campaign, the Village of Yellow Springs, where Antioch is located,  is  considering an organic land care policy, and Beyond Pesticides is working with the Village to assist with a transition to organic turf care. “At Antioch College, we have an opportunity, and an urgency, to be change leaders in turning around pollinator decline, exposing misleading research and recognizing the importance of inter-species cooperation. To paraphrase our president Thomas Manley, ”˜If we are not leaders in discovering and implementing  new and better ways of living  , then what is the point?’” said Beth Bridgeman, the faculty member who drove the effort to ban neonicotinoids from campus. Antioch students and staff maintain about […]

City of Milwaukie, OR Passes Resolution to Protect Pollinators

(Beyond Pesticides, April 25, 2016) Last week, the City Council of Milwaukie, Oregon passed a resolution that halts the use of bee-toxic neonicotinoid insecticides on city government and public property,  joining the growing number of local governments protecting pollinators.  Neonicotinoids  (neonics) have been widely cited in the demise of both managed and wild bee and pollinator populations.  The resolution specifically  restricts city government agencies from purchasing plants and seeds that have been treated with neonicotinoids and other systemic insecticides and urges public and private landscapers and homeowners to plant bee-friendly habitats.  Clackamas County will join with the Mayor’s office and City Council of Milwaukie to adopt an Integrated Pest Management Plan that mirrors the resolution. In addition to these stipulations, the City of Milwaukie is using this resolution to: urge all businesses, homeowners, and homeowner’s associations operating within the City ensure no plants, seeds, or products containing neonicotinoids are purchased, sold, or used within the City; and to clearly and accurately label any plants or materials that have been treated with a neonicotinoid or neonicotinoid-like insecticide; require that commercial pest service providers performing services on behalf of the City provide landscape services that encourage pollinator populations and support pollinator services; […]

Help Protect Pollinators Today, Earth Day

(Beyond Pesticides, April 22, 2016) Today is Earth Day! As honey bees and other pollinators continue to suffer from staggering global declines, Beyond Pesticides works year-round through the BEE Protective campaign, launched Earth Day 2013, to support nationwide local action aimed at protecting pollinators from pesticides. Pollinators are a vital part of the environment, a barometer for healthy ecosystems, and critical to the nation’s food production system. With one in three bites of food reliant on bees and other species for pollination, the decline of honey bees and other pollinators demands swift action. The BEE Protective campaign includes a variety of educational materials to help encourage municipalities, campuses, and individual homeowners to adopt policies and practices that protect bees and other pollinators from harmful pesticide applications and create pesticide-free refuges for these critical  organisms. In addition to scientific and regulatory information, BEE Protective also assists people and communities with  a model community pollinator resolution and a pollinator protection pledge. Insecticides, specifically neonicotinoids, have increasingly been linked to bee declines. These chemicals are used extensively in U.S. agriculture, especially as seed treatment for corn and soybeans. Agriculture is not the only concern however, as pesticide applications in home gardens, city parks, […]

Maryland Legislature Bans Retail Sales of Bee-Toxic Neonicotinoid Pesticides

(Beyond Pesticides, April 11, 2016) In a historic move, the Maryland legislature voted to become the first state in the nation to ban consumers from using products containing neonicotinoid pesticides, a class of bee-toxic chemicals that has been linked to the startling decline in bees and other pollinators around the world. The bill now heads to Governor Larry Hogan to sign or veto. The Pollinator Protection Act was approved by lawmakers on Thursday by  a 98-39 vote in the Maryland House of Delegates. While consumers will not be allowed to buy pesticide products containing neonicotinoids starting in 2018, the legislation’s  reach does not extend to farmers, veterinarians, and certified pesticide applicators, who will still be permitted to apply  the chemicals. Consumers can also buy treated plants and seedlings from stores without any labeling. Cumulatively, these present major sources of exposure for bees and other pollinators. The bill originally included a requirement that companies put labels on plants and seeds that are treated with neonicotinoids, but that provision was ultimately pulled from the bill. Hardware stores  like Home Depot and Lowe’s  had previously announced that they were voluntarily phasing out the supply of neonicotinoid-treated plants over the next two to three […]

Small Size of Wild Bees Correlated with Their Proximity to Intensive Agriculture

(Beyond Pesticides, April 5, 2016) Populations of wild, ground-nesting bees grow smaller in areas where agricultural production is high, according to Cornell University researchers. Both wild and managed pollinators are experiencing global population declines that have been linked to a range of factors stemming from human activity, to habitat loss, the spread of parasitic mites and diseases, climate change, and significantly, the use of toxic, systemic pesticides. This study underscores the wide ranging threat that conventional agricultural practices pose to wild insect pollinators. Cornell researchers explore the relationship between intensive agricultural production and the size of ground-nesting Andrena nasonii bees. These charismatic pollinators dig tunnels in the ground up to three  feet deep in which they store honey and nectar, and ultimately lay a single egg. They forage on a variety of fruit crops, and are well known and important pollinators of strawberries. Thus, scientists brought their study to areas in New York with large strawberry plantations. Researchers discovered a significant, positive correlation between the decreased size of female A. nasonii bees and their proximity to intensively farmed strawberry plots. “Once we knew there was an effect of agriculture on the size of the bees, we took a random sample […]

Minnesota Beekeepers Compensated for Bee Kills from Pesticide Drift

(Beyond Pesticides, March 28, 2016) In the first test of a landmark beekeeper compensation law that works to protect beekeepers from the effects of toxic pesticides on their hives, Minnesota has recently compensated two beekeepers for pesticide drift that killed their bees. Investigators from the Minnesota Department of Agriculture (MDA) have confirmed what beekeepers and environmentalists have been saying: Even when pesticides are used in accordance with the label and the law, they can be acutely toxic to bees in everyday circumstances. Pam Arnold, an organic farmer who manages hives on her property, and Kristy Allen, another beekeeper who shares the same bee yard, were the first two beekeepers to actually receive compensation through the beekeeper compensation law. Last spring, a farmer across their road planted neonicotinoid (neonic) coated corn seeds on a windy day, resulting in the death of their bees as toxic dust from planting drifted on to their property. Tests performed by MDA during the investigation found acute levels of clothianidin in the dead bees, even days after the incident. Nearby dandelion weeds also showed significantly higher concentrations of the toxin. According to the MDA website, the case closing letter was sent in November 2015, but they […]

Study Finds Bees’ Pollination Skills Impaired by Pesticides

(Beyond Pesticides, March 16, 2016) Another study, this time from researchers at the University of Guelph, finds that at very low levels the neonicotinoid pesticide thiamethoxam affects  the foraging behavior of bumble bees, changing their floral preferences, hindering their ability to learn and extract nectar and pollen. This study is one of many that detail the negative effects of pesticides on bees’ learning behavior and ability to pollinate essential crops. Pesticides, like the neonicotinoid class of insecticides, have been implicated in the global decline of pollinator populations, while advocates call for  limiting pesticide exposures to reverse population declines. According to the authors of this Canadian study, “Chronic exposure to a neonicotinoid pesticide alters the interaction between bumblebees and wild plants, “published in  the journal Functional Ecology, it is the first to explore how pesticides may impact the ability of bumble bees to  forage from common wildflowers that have complex shapes such as white clover and bird’s foot trefoil. The researchers found that bumble bees exposed to environmental levels of thiamethoxam (10ppb) took longer to collect pollen than unexposed bees, as well as foraged from different flowers. Importantly, this study reports that bumble bees that were not exposed to thiamethoxam are […]

GAO Report Finds USDA, EPA Not Doing Enough to Protect Pollinators

(Beyond Pesticides, March 15, 2016) Executive agencies are falling short in their efforts to protect honey bees and other wild pollinators from catastrophic declines, according to a new report from the U.S. Government Accountability Office (GAO). GAO, an investigative agency that works on behalf of the U.S. Congress, was tasked by the Senate to evaluate the progress the Environmental Protection Agency (EPA) and U.S. Department of Agriculture (USDA) have made in their actions to address the multiple threats contributing to declining managed and wild pollinators. Since 2006, U.S. beekeepers have experienced unsustainable colony die-offs, averaging over 30% each year. Concurrent declines in wild and native pollinators are also occurring, though data on the magnitude of these losses have not undergone comprehensive scientific evaluation. While a range of factors, from habitat loss, to climate change, diseases, viruses, and parasites are all contributing to these declines, independent science has identified that pesticides, specifically a new class of systemic insecticides called neonicotinoids, are the major drivers of the crisis for both managed and wild bees. In fact, some studies show that the widespread exposure to neonicotinoids increases bees’ vulnerability to diseases, viruses, and mites. The GAO report recommends a number of action items […]

“Muzzled” USDA Scientist to Speak at National Pesticide Forum

(Beyond Pesticides, March 10, 2016) Jonathan Lundgren, Ph.D., a top U.S. Department of Agriculture (USDA) entomologist who received a prestigious national award for civic courage  for his work on neonicotinoids and pollinator decline in the face of agency attempts to suppress his work, will be speaking at Cultivating Community and Environmental Health, the 34th National Pesticide Forum, April 15-16, 2016 in Portland, ME. Dr. Lundgren will join other top scientists and leaders who have stood up to protect human and environmental health, despite facing industry backlash and scientific suppression. His story was recently featured in Sunday’s The Washington Post Magazine, Was a USDA Scientist Muzzled Because of His Bee Research, as censorship of federal scientists has grown. As a Senior Research Entomologist and Lab Supervisor for the Agricultural Research Service (ARS) in South Dakota, Dr. Lundgren had worked for USDA for eleven years with great success, with his research drawing national attention and international recognition. However, in October 2015, Dr. Lundgren, represented by Public Employees for Environmental Responsibility (PEER) filed a whistleblower complaint charging the agency with suppression of research findings that challenged the safety and efficacy of a widely used class of pesticides, neonicotinoids. In April 2015, PEER filed […]

UN Report Warns of Decline in Pollinators and Global Food Supplies

(Beyond Pesticides, March 7, 2016) A United Nation’s report, released late last month, has warns the world that many species of wild bees, butterflies and other pollinators are on a dangerous path toward extinction, and that the  food supply will suffer if the causes of these declines, many of them human-made, are not stopped. The report is based on  many different scientific studies. The scientists who led the assessment pointed to pesticides as one of the leading causes of pollinator decline, specifically, a class of toxic chemicals called neonicotinoids, which adversely affect the nervous system of insects. According to their press release, the assessment,  Thematic Assessment of Pollinators, Pollination and Food Production, is the first ever issued by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem  Services (IPBES). IPBES was founded in 2012 with 124 member nations to “form a crucial intersection between international scientific understanding and public policy making.” Before its release, the assessment attracted some controversy for including two representatives from the agrochemical industry, including Bayer CropScience and Syngenta, as lead authors. Even though the IPBES requires all lead authors to complete conflict-of-interest statements, some scientists and environmentalists expressed concern. Given the roll of agrochemicals in pollinator decline, […]

Chlorpyrifos Reduces Memory and Learning in Exposed Bees

(Beyond Pesticides, March 4, 2016) Honey bees experience a learning and memory deficit after ingesting small doses of the insecticide  chlorpyrifos, potentially threatening their success and survival, according to a study in  New Zealand. Chlorpyrifos is a highly neurotoxic organophosphate pesticide used worldwide on crops to protect against insects and mites. The study,  Measurements of Chlorpyrifos Levels in Forager Bees and Comparison with Levels that Disrupt Honey Bee Odor-Mediated Learning Under Laboratory Conditions,  published in  Ecology, examines chlorpyrifos levels in  bees collected from 17 locations in Otago, New Zealand and compared doses of the pesticide that cause sub-lethal effects on learning performance under laboratory conditions with amounts of chlorpyrifos detected in bees in the field. Researchers found chlorpyrifos in 17% of the sites sampled and 12% of the colonies examined. Honey bees are found to experience harmful effects to smell memory and learning, and reduction in specificity of memory recall. Chlorpyrifos is just one of many pesticides that have frequently been detected in honey bees. According to a study conducted last year by the U.S. Geological Survey (USGS), 72% of bees tested positive for pesticide residues, raising concerns about  unintended pesticide exposures where land uses overlap or are in proximity […]

Glyphosate Residues in Popular German Beers

(Beyond Pesticides, February 29, 2016) Last Thursday, the Munich Environmental Institute stated that it had found traces of glyphosate, the widely used and controversial weed-killer, in 14 of Germany’s most popular beers. These findings are a potential blow to Germany’s Beer Purity Law, which is highly regarded in German beer culture. Industry and German government immediately sought to downplay the results, saying that the levels found did not pose a risk to humans. However, according to the study’s results, all levels found were above the glyphosate residue level allowed in drinking water. Consumers have a right to be worried about the findings, as glyphosate was classified in March 2015  as a probable carcinogen by the International Agency for Research on Cancer (IARC). The results, published  in German, are broken down by beer and by micrograms per liter in picture format. The researchers cite the laboratory test results of the 14 beers, which found glyphosate levels  between 0.46 and 29.74 micrograms per liter. The highest reading is 300 times the legal limit for drinking water in Germany, which is 0.1 microgram per cubic meter. Hasseroeder, a beer brewed in Saxony-Anhalt in eastern Germany and owned by Anheuser Busch Inbev, contained the […]
