(Beyond Pesticides, March 22, 2019) A two-year study, published March 14, finds that field-relevant contamination with the neonicotinoid insecticide imidacloprid causes reduced body weight and metabolism in white-tailed deer, and â in fawns â mortality. Remarkably, researchers uncovered imidacloprid levels in free-ranging deer a full 3.5 times higher, on average, than the levels in the animals treated in their experiment. These new findings add to the mounting evidence of the hazards posed by current patterns of neonicotinoid use, while evidence of benefits remains sparse. The study, published in Nature Scientific Reports, includes two years of data on the physiological and behavioral outcomes of imidacloprid contamination in 80 white-tailed deer housed in a South Dakota State University captive research facility. Notably, researchers were unable to entirely control imidacloprid levels in untreated deer, most likely due to background contamination from corn- and soy-based feed, and surrounding vegetation infiltrated by runoff from nearby agricultural fields. This background contamination altered, but did not compromise, the analysis. Researchers found that imidacloprid levels detected in the spleens of treated and control animals were significantly predictive of reduced thyroid hormone levels, shorter jawbones, lower activity levels, and higher fawn mortality.

(Beyond Pesticides, March 19, 2019) Research is beginning to explain how systemic neonicotinoid insecticides affect often overlooked species of ground nesting bees. While much of the current scientific literature has focused on the impacts of pesticides to bumblebees and honey bees, a study, Chronic contact with realistic soil concentrations of imidacloprid affects the mass, immature development speed, and adult longevity of solitary bees, recently published in Scientific Reports, confirms that wild, soil-dwelling bees are at similar risk. As policy makers consider ways to protect pollinators, this research finds that uncontaminated soil is an important aspect of ensuring the health of wild, native bees. âThis is an important piece of work because itâs one of the first studies to look at realistic concentrations of pesticides that you would find in the soil as a route of exposure for bees,â said Nick Anderson, co-author of the study. âItâs a very under-explored route, especially for some of the more solitary species that nest in the ground.â In order to study the impact of neonicotinoids on ground nesting bees, researchers used orchard mason bees and leafcutter bees as proxies, as they are easier to gather and rear in the lab, and have a similar ecology […]

(Beyond Pesticides, March 14, 2019) A study, supported by the USDA’s National Institute of Food and Agriculture, finds that state pesticide preemption laws âcompromise public health and economic well-beingâ by preventing localities from enacting pesticide use restrictions on private property that are more restrictive than their state’s regulations. In the words of the authors, âBy eliminating the ability of local governments to enact ordinances to safeguard inhabitants from health risks posed by pesticides, state preemption laws denigrate public health protections.â The study, Anti-community state pesticide preemption laws prevent local governments from protecting people from harm, published in the International Journal of Agricultural Sustainability, reviews scientific and historical evidence of the failure of state and federal pesticide laws to protect localities from pesticide poisoning, and highlights the inability of localities to compensate for that failure under present laws. Communities seeking to protect their residents would typically issue community-wide restrictions to ensure protection of shared community resources, including air, land, and waterways, from pesticide drift, runoff, and other nontarget effects âas is the case with other community decisions on recycling, smoking, and zoning. The study’s authors document how industry influence led to the adoption of state laws that undermine the ability of localities […]

(Beyond Pesticides, March 13, 2019) A study on the impact of two neonicotinoid pesticides shows differential gene expression in bumblebees (Bombus terrestris) after exposure. Considering the current worldwide plight of insects, the authors of point to the cutting edge research as both a reason and a methodology to more carefully examine the effects of pesticides. âCaste- and pesticide-specific effects of neonicotinoid pesticide exposure on gene expression in bumblebeesâ was published in the journal Molecular Ecology in early March. Researchers fed variable colonies with clothianidin or imidacloprid-laced sucrose. They analyzed gene expression in the heads of worker bumblebees and colony queens using RNA sequencing (RNA-seq), inspired by biomedical techniques. This approach allowed for new insight on what genes and pathways are affected by neonicotinoid exposure. Study author Yannick Wurm, PhD, stated in a press release, âOur work demonstrates that the type of high-resolution molecular approach that has changed the way human diseases are researched and diagnosed, can also be applied to beneficial pollinators. This approach provides an unprecedented view of how bees are being affected by pesticides and works at large scale. It can fundamentally improve how we evaluate the toxicity of chemicals we put into nature.â Clothianidin had a stronger […]

(Beyond Pesticides, March 7, 2019) A publication in the journal Environmental Health Perspectives highlights findings from a recent study showing that environmental concentrations of the neonicotinoid insecticides thiacloprid and imidacloprid increase expression of a gene linked to hormone-dependent breast cancer. Authors of the featured study uncovered a pathway through which neonicotinoids stimulate excess estrogen production, known to occur during the development of progressive hormone-dependent breast cancer. In the words of the authors, âOur findings highlight the need for further research to assess the potential impacts of low-dose and chronic exposure to neonicotinoids on endocrine processes affecting womenâs health.â The study, published in Environmental Health Perspectives in April 2018 by researchers at the University of Quebec, is not the first to point to a potential link between neonicotinoid exposure and breast cancer. A 2015 study by the same research group revealed that the neonicotinoids thiacloprid and thiamethoxam, along with the herbicide atrazine, induce similar effects in breast cancer cells. In both studies, exposure to neonicotinoids alter promoter activity to induce heightened production of the enzyme aromatase, which is known to stimulate estrogen production and thereby cancer cell proliferation. The recently published study, authored by Silke Schmidt, PhD, brings greater urgency to […]

(Beyond Pesticides, March 4, 2019) Last week, U.S. Representative Earl Blumenauer (D-OR) reintroduced the Saving Americaâs Pollinators Act (H.R.1337) to cancel specific bee-toxic pesticides and establish a review and cancellation process for all pesticides that are potentially harmful to pollinators. The specific pesticides targeted in the bill include the systemic insecticides imidacloprid, clothianidin, thiamethoxam, dinotefuran, acetamiprid, sulfoxaflor, flupyradifurone, and fipronil. The bill also establishes requirements for review of other potentially bee-toxic chemicals by an independent pollinator protection board, and requires annual reports on the health and population status of pollinators. The bill creates a sustainable model for pollinator protection in the face of ongoing obstruction by an increasingly industry-influenced EPA. There are 29 cosponsors to date. The current bill is the fifth version of Saving America’s Pollinators Act (SAPA), which was first introduced by U.S. Representative Conyers (D-MI) in 2013. The newest version differs from previous bills in its bold definition of who should have responsibility for assessing harm to pollinators. SAPA 2019 calls for the establishment of a Pollinator Protection Board, to be composed of expert scientists, beekeepers, farmers, members of environmental organizations and other key stakeholders, nearly all of whom must not have any conflict of interest or affiliation […]

(Beyond Pesticides, February 26, 2019) Breakfast cereal, apples, applesauce and pinto beans made and sold by Kroger contain residues of toxic pesticides linked to a range of series health and environmental problems, according to a residue study by Friends of the Earth. This is alarming. Kid-friendly food like applesauce and Cheerios should not contain dangerous pesticides. Kids are the most vulnerable to these pesticides and shouldn’t be exposed to brain-damaging or cancer-causing pesticides when they eat their breakfast or snacks. The connection between pesticides and cancer, learning disabilities, and other diseases is supported by hundreds of studies in Beyond Pesticidesâ Pesticide-Induced Diseases Database. These new tests, which corroborate numerous residue studies, mean that Kroger customers may be purchasing food with the intent of providing safe and healthy food for their families, but end up unknowingly exposing them to toxic pesticides. Join the national week of action by either delivering a letter to Kroger in person, or sending an email to Kroger Chief Executive Rodney McMullen. The pesticides found in Kroger’s food are harmful to human health and pollinators. Friends of the Earth found residues of cancer-causing glyphosate, brain-damaging organophosphates, and bee-killing neonicotinoid pesticides. Organophosphates can cause damage to children’s developing brains, including reduced IQ, loss […]

(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, February 13, 2019) Friends of the Earth (FOE) released a report last week again showing pesticide residues in the food supply. The report, Toxic Secret, found store and name brand foods produced and sold by the top four U.S. food retailers â Kroger (NYSE:KR), Walmart (NYSE: WMT), Costco (NYSE:COST) and Albertsons â contain residues of toxic pesticides linked to a range of serious health and environmental problems. Among the pesticides found is the herbicide glyphosate, confirming residue testing results found in numerous studies. Glyphosate, the active ingredient in Roundup, has has been detected in popular foods, including â100% pureâ honey, Doritos, Oreos, Goldfish, Ritz Crackers, German beers, California wines, and UK bread. Glyphosate has been ranked as potentially cancer causing in humans and adversely affects the human gut microbiome. See Residue Testing Find More Glyphosate in Popular Cereals. The FOE study finds that oat cereals, apples, applesauce, spinach and pinto beans at the retailers contained detectable amounts of glyphosate, organophosphates and neonicotinoids. The average level of glyphosate found in cereal samples (360 parts per billion) was more than twice the level set by scientists at Environmental Working Group for lifetime cancer risk for children. The average level of glyphosate found in pinto beans (509 ppb) was more […]

(Beyond Pesticides, February 11, 2019) A new systematic review of insect population studies worldwide reports on âthe dreadful state of insect biodiversity in the world, as almost half of the species are rapidly declining and a third are being threatened with extinction.â The study concludes with the dire prediction that insects as a whole will go extinct in the next few decades if patterns of intensive agriculture, in particular pesticide use, continue. The review, published in Biological Conservation, analyzes 73 insect population studies conducted within the past 40 years, filtered to include only those that quantitatively assess all insect species within a taxa over a span of 10 or more years. Researchers Francisco SĂĄnchez-Bayo, PhD and Kris A.G. Wyckhuys, PhD uncover the disturbing truth behind this mass of data: one in every three insect species monitored worldwide is threatened with extinction. Even more concerning is the finding that 41% of insect species worldwide are in decline, outpacing the more well-publicized vertebrate declines by 200%. Only a few species are expanding in range or occupying vacant niches â not nearly enough to compensate for the massive losses. In 8% of the studies in the review, citizen science data is analyzed in […]

(Beyond Pesticides, February 8, 2019)Â Scientists from the U.S. Geological Survey (USGS) and the University of Iowa (UI) have published worrisome news on the neonicotinoid front. The experts discovered two metabolites of imidacloprid (a neonicotinoid insecticide) residues that had not previously been identified in drinking water â desnitro-imidacloprid and imidacloprid-urea. The researchers note both that these metabolites have never been evaluated for their potential risks to human and environmental health, and that there may be potential risks of anthropogenic compounds that can be created when water with neonicotinoid residues, and thus, these metabolites, undergo typical water treatment (often chlorination and/or pH treatment). They note that, âThe mammalian toxicity of transformation products formed during water treatment processes remains unknown. It is possible that chlorination of neonicotinoids and their metabolites will . . . alter their bioactivity.â The joint, federally funded collaboration investigated neonicotinoid pesticides (âneonicsâ) in tap water to determine whether neonic metabolites are relevant to pesticide exposure through drinking water, and to identify any products of the chlorination of neonics and their metabolites. The scientists simulated realistic drinking water conditions in their research to demonstrate, in laboratory circumstances, that chlorinated disinfection byproduct chemicals are produced. The study, conducted by seven researchers […]

(Beyond Pesticides, February 7, 2019) A new study, released in Environmental Science and Policy, systematically reviews all state-level pollinator protection acts passed since 2000 and makes a somewhat dim diagnosis: as a rule, state policies fall far below the mark for protecting invaluable ecosystem services and ensuring long-term, sustainable food production. Authors judge the legislation against a set of pollinator protection policy benchmarks established in 2016 by a group of scientists from the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES). Citing the ten policy recommendations laid out by IPBES experts, researchers point to the failure of all enacted state policies to address three main target areas â (1) to improve genetically modified crop risk assessment, (2) to incentivize farmers to make the switch from agrochemical dependence to sustainable benefits from ecosystem services, and, critically, (3) to support diversified farming systems. Beyond Pesticides notes one additional missed target: (4) funding for research on organic, diversified, and ecologically intensified farming. The study includes a total of 109 state laws passed from 2000 to 2017, which authors tracked down by searching usa.gov and state legislative websites and by submitting requests to state librarians. To uncover common themes and patterns among these […]

(Beyond Pesticides, January 4, 2019) First, the good news: plaintiffs in a 2013 lawsuit against the Environmental Protection Agency (EPA) can allow themselves a small victory dance. In that suit, plaintiffs made a number of claims related to EPAâs failure to protect pollinators from dangerous pesticides, its poor oversight of the bee-killing pesticides clothianidin and thiamethoxam, and its practice of âconditional registration,â as well as labeling deficiencies. The parties in the suit negotiated a settlement, as directed by a federal judge (see below), that was signed in October 2018 and portends some positive movement in curtailing the use of some toxic pesticides [12 products, each of which contains chlothianidin or thiamathoxam as an active ingredient] that harm pollinators in particular, as well as other organisms and the environment. It also establishes a public process for EPA to consider requiring whole formulations of pesticide products during registration, and redefining EPA’s interpretation of law that allows seeds treated with bee-toxic pesticides to escape regulation as a pesticide. The suit was brought by a number of individual beekeepers and several organizations, including Beyond Pesticides, Center for Food Safety (CFS), Sierra Club, and Center for Environmental Health, and named as defendants Steven Bradbury, then-director of the […]

(Beyond Pesticides, January 3, 2019) Bee-toxic pesticides banned for consumer use by the state of Maryland are still being sold in hardware and garden stores, according to reports from beekeeper and consumer watchdog groups. In 2016, Maryland passed the Pollinator Protection Act, which limited the use of neonicotinoids, insecticides implicated in the global decline of pollinator populations, to only certified applicators. According to spot checks by the Maryland Pesticide Education Network (MPEN) and the Central Maryland Beekeepers Association (CMBA), state enforcement agencies still have a ways to go to ensure retailers are complying with the law. From May to October 2018, six volunteers visited 30 Maryland stores along the Baltimore-Washington corridor to see whether they are complying with the law by removing bee-toxic neonicotinoids from retail consumer sale. Eleven of the 30 stores were not in compliance, ranging from local home and garden stores to national big-box chains. âIâve taken bottles off the shelf and taken them up to an employee or a manager, and said, âYou really need to stop selling this stuff â itâs illegal,ââ said Steve McDaniel, a master beekeeper in Carroll County to the Bay Journal. The state, for its part, indicates that staffing problems at […]

(Beyond Pesticides, December 14, 2018) The richness, diversity, and abundance of wild bumblebees in Vermont has plummeted over the last century, according to an analysis from researchers at the University of Vermont and Vermont Center for Ecostudies (VCE). This research adds fresh evidence to the growing realization that mankind is witnessing and contributing to, as the New York Times recently labeled, a worldwide insect apocalypse. “We’re losing bumblebees even before we fully understand their benefits to our economy and well-being, or how they fit into ecosystems,” said Kent McFarland, study coauthor and conservation biologist at VCE in a press release. Researchers conducted surveys with the help of 53 trained citizen scientists. Alongside the researchers, these individuals surveyed bumblebee populations through a combination of photos of wild bees and net collections. In total, over 81% of the stateâs municipalities were included in the survey, representing all of Vermont pollinatorâs biophysical regions. These data, consisting of over 10,000 bee encounters, were then compared to a database of almost 2,000 historical public and private insect collections amassed by researchers. With the first records beginning at 1915, scientists are able to compose a century-long assessment of pollinator populations in Vermont. âThese collections are priceless,” […]

(Beyond Pesticides, December 3, 2018) In August 2018, the Trump administration announced a reversal of a 2014 U.S. Fish and Wildlife (FWS) decision to ban neonicotinoid insecticides on National Wildlife Refuges. The administrationâs action threatens not only pollinators, but contributes to the attack on biodiversity worldwide.  Tell Congress to protect biodiversity by insisting that the ban on neonicotinoid pesticides in wildlife refuges be reinstated. In 2014, FWS announced that all National Wildlife Refuges would join in the phase-out of neonics (while also phasing out genetically engineered crops) by January 2016. FWS âdetermined that prophylactic use, such as a seed treatment, of the neonicotinoid pesticides that can distribute systemically in a plant and can potentially affect a broad spectrum of non-target species is not consistent with Service policy. We make this decision based on a precautionary approach to our wildlife management practices and not on agricultural practices.â This move was not only intended to protect honey bees that have suffered average losses above 30% since 2006, but also the federally threatened and endangered pollinators that live in National Wildlife Refuges. However, it is not just pollinators who are affected. Recent research has found dramatic drops in overall insect abundance, leading entomologists to speak of an âinsect apocalypse.â Various studies have found reductions of up to […]

(Beyond Pesticides, November 28, 2018)Â 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 â the most widely used category of pesticides worldwide â 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 beesâ typical construction of an insulating wax canopy for the nest, and poor caretaking can affect brood growth. Investigators noted that, âNeonicotinoids 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.â The authors also observed that many of these dysregulated behaviors were more pronounced at night than during sunlight hours, and […]

(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 1, 2018) A new study offers fresh evidence that wild bumblebee pollinators are particularly vulnerable to the impacts of neonicotinoid (neonic) insecticides, finding that exposure to these compounds interferes with mating success and population stability. Researchers from Worcester Polytechnic Institute in Massachusetts, measuring real-world harms of neonicotinoids, indicate that the impacts they found to bumblebee âreproducers,â namely queen and drone (male) bees, does not bode well for the array of plant species that relies on them. Though advocates warn that destabilizing managed pollinators could threaten U.S. food production and exports, with food prices increasing as cost of bringing pollinators to farms increases, the studyâs authors and advocates insist that the impacts of such widespread poisoning of wild bees could be felt well beyond agriculture. Researchers in the lab compare behavioral and psychological responses of virgin queens, workers, and male Bombus impatiens from multiple colonies to field-realistic doses of the neonicotinoid clothianidin. While every bee was given a replenishing supply of pollen based on body weight and energy demands, four distinct concentrations of diluted analytical-grade (pure) clothianidin (including a control with no pesticide added) were mixed into a nectar-like solution and fed to the bumblebees orally for 5 […]

(Beyond Pesticides, October 25, 2018) A study published last month in Scientific Reports finds that eating sunflower pollen significantly reduces protozoan infection in bumblebees. Studying ecosystem services and what she calls âfloral rewards,â evolutionary ecologist Lynn Adler, Ph.D. at the University of Massachusetts Amherst says sunflowers may provide a long sought after solution for improving beesâ immune system response to both disease and parasites. The researchers studied the protozoan Crithidia bombi, a common parasitic infection of bumble bees, known to impair learning and foraging, shorten lifespan and destabilize colony hierarchies by impacting queen bee behavior. From the outset of the study, Dr. Adler says, âthe more sunflowers were grown at the farm, the lower the Crithidia load for the bees at that farm.â Knowing pollinators eat pollen as a source of protein and healthy fats, Dr. Adler hypothesized that both pollen and nectar might have medicinal effects against disease and parasites. However, her experiment did not show consistent results with nectar. After bees in the lab were starved for 4-6 hours, researchers fed individual worker bees from small colonies a drop of fructose fluid containing 6,000 Crithidia cells, being the approximate concentration bees may encounter in the wild while foraging. After […]

(Beyond Pesticides, October 19, 2018) Pollinator advocates and the Center for Biological Diversity (CBD) are imploring the U.S. Environmental Protection Agency (EPA) to deny Bayer CropScienceâs application for use of âSivanto,âa pesticide product with the active ingredient flupyradifurone, a chemical the company claims is safer for bees, but poses the same risks at the notorious bee-toxic neonicotinoid insecticides. If approved, Sivanto would be sprayed in tobacco-growing states along 300,000 acres in the southeast U.S., areas home to more than three dozen species protected under the Endangered Species Act (ESA). Bayerâs proposal for expanded uses comes after EPAâs own assessment indicated risks to endangered species, and despite the fact that the agency has not undergone an ESA mandated consultation with federal wildlife agencies. For the countless flying insects, birds, and bats already under significant threat from neonicotinoids, adding another systemic insecticide to the mix will only make the situation worse. Bayer AG is characterizing flupyradifurone as being harmless to honeybees. However, flupyradifurone, being a systemic pesticide, can negatively impact many non-target species. In fact, flupyradifurone impacts honey bee brains in a similar way to neonicotinoids, as it impairs learning, memory and the honey beesâ affinity for nectar rewards. Advocates worry that growing […]

(Beyond Pesticides, October 15, 2018) As a leader in organic sales, it is critical that Kroger take additional expedited steps to increase the market share of organic food and eliminate the use of toxic pesticides harmful to public health and the environment. Kroger is among the major food retailers that sells food that has been grown with toxic pesticides, such as the extremely hazardous insecticide chlorpyrifos which causes neurological and brain damage in children. Kroger should immediately end its misleading and fraudulent advertising and labeling of food products as ânaturalâ and replace these with certified organic products. In fact, by misleading consumers with ânaturalâ labeling and advertising of food, Kroger supports chemical-intensive agriculture that poisons children, causes cancer, and threatens biodiversity through the use of toxic chemicals like chlorpyrifos, glyphosate, and neonicotinoids. This is unnecessary and unacceptable. Tell Kroger to stop selling food grown with toxic pesticides. Chlorpyrifos  is a highly neurotoxic organophosphate pesticide that is linked to neurologic developmental disorders in children. Exposure to even low levels of organophosphates like chlorpyrifos during pregnancy impairs learning, changes brain function, and alters thyroid levels of offspring into adulthood. EPAâs own assessment finds that children exposed to high levels of chlorpyrifos have developmental delays, attention problems, attention-deficit/hyperactivity disorder […]

(Beyond Pesticides, October 10, 2018) Nearly one-third of General Mills shareholders called on the company last month to improve product stewardship and eliminate pesticides like bee-toxic neonicotinoid insecticides or the probable carcinogenic weed killer glyphosate from its supply chain. The proposal was put forward by nonprofit organization As You Sow, and Green Century Equity Fund (GCEF), a mutual fund. This is the latest public shareholder action GCEF has made in regards to corporate pesticide reform, with the company previously putting pressure on the Dr. Pepper Snapple Group for its allowance of pesticides within its supply chain. While the actions are encouraging, some advocates are urging shareholder groups to go beyond increased accountability and transparency and push companies to focus on sourcing organic to ensure that no pesticides make their way into food products. The shareholder proposal ultimately garnered support from 31% of General Mills shareholders. âShareholders believe the company can, and should, do more to protect the health of their supply chain and the public from toxic pesticides,â said Christy Spees, environmental health program manager at As You Sow to the StarTribune. The proposal states, âWhile the company asserts that it is currently âdocument[ing] continuous improvementâ concerning environmental impacts from its supply […]
