(Beyond Pesticides, March 22, 2013) Whole Foods Market Inc, Trader Joe’s, Aldi, and other food retailers representing more than 2,000 U.S. stores have committed not to sell genetically engineered (GE) salmon. This announcement from the Campaign for Genetically Engineered-Free Seafood appears to be strategic, as the U.S. Food and Drug Administration (FDA) nears its decision on the introduction of GE Atlantic salmon from AquaBoutny Technologies into the marketplace. The announcement is being hailed as a victory for environmental and consumer protection groups who are now engaged in GE labeling fights across the country. The announcement also helps underscores the belief that consumers and food retailers are growing increasingly skeptical of the safety and necessity of GE food products. The food retailers that have signed against the sale of GE salmon range from large food distributors, such as Trader Joe’s, to smaller businesses like Sacramento Natural Foods Cooperative. The commitment also came from stores that ranged from the more upscale Whole Foods to the discount grocer Aldi. Proponents of the campaign argue that genetically modified products are not sufficiently tested for safety, carry allergy risk, and also should be labeled. AquaBounty argues that these GE fish are sterilized and would be […]

(Beyond Pesticides, March 20, 2013) Loss of habitat to genetically engineered (GE) cropland, as well as increasingly warm temperatures are responsible for the dramatic decline in Monarch butterfly populations, according to scientists who say populations are the lowest they have seen in two decades.  This comes as the state of pollinators continues to reach crisis levels, with honey bee colonies also experiencing alarming declines. Scientists who take the annual measure of Mexican forestland famously occupied by migrating monarch butterflies find that forestland occupied by the butterflies, once as high at 50 acres, dwindled to 2.94 acres. This is a 59 percent decline from the 7.14 acres of butterflies measured in December 2011. The survey carried out in December and January, reported nine monarch colonies wintering in central Mexico, occupying a total of 1.19 hectares, or 2.94 acres. The results were released by the World Wildlife Fund-Mexico, and Mexico’s National Commission of Natural Protected Areas (CONANP). This population is the smallest recorded since the Monarch colonies came to the attention of scientists in 1975. To explain this drastic decline, researchers point to the loss of Monarch habitat in the U.S. and Mexico to increasing cropland and the widespread use of the […]

(Beyond Pesticides, March 14, 2013) A group of over one hundred food businesses and retailers, and family farm, consumer, health, environmental and civil liberties groups, lead by Center for Food Safety and including Beyond Pesticides, have united to support an amendment by Senator John Tester (D-MT) (D-MT) to strike   a dangerous biotech policy rider into the Continuing Resolution (CR) now being debated on the Senate floor. The biotech industry has quietly inserted the “biotech rider” (Sec. 735) into the proposed Senate CR to end judicial oversight of the regulation of genetically engineered (GE) crops. Groups say that this represents a serious and unique assault on the fundamental safeguards of our judicial system, and would negatively effect farmers, the environment, and public health across America. We urge you to call your Senators to demand that Appropriations Chairwoman Barbara Mikulski (D-MD)pull this dangerous and unconstitutional rider, and support the Tester amendment to preserve judicial oversight over regulatory decisions the allowance of GE crops: Find your Senators’ numbers here, or call the U.S. Capitol Switchboard at (202)224-3121 and ask for your Senators’ office. This dangerous rider was not included in the House-passed CR, and food safety, environmental and farm groups are extremely […]

(Beyond Pesticides, March 12, 2013) Despite the loss of Proposition 37 in California last November, GMO labeling efforts are moving forward throughout the United States. Late last week Whole Foods Market announced its own plan to label food with genetically engineered (GE) ingredients sold in its stores, making it the  first grocery chain in the nation to do so. In addition to the recent introduction of a National GE labeling bill in Congress by Representative Jared Polis (D-CO), Hawaii, Vermont, and Minnesota join the ranks of numerous other states with pending GMO labeling legislation. Whole Foods’ plan  requires a label for all GE food sold in its stores within the next  five years. The retailer notes that the move was made in response to customers’ increased demand for labeled products. “Some of our manufacturers say they’ve seen a 15 percent increase in sales of products they have labeled [as non–GMO],” explains A.C. Gallo, Whole Foods president. The chain’s labeling requirements include all of its North American stores, as its European supermarkets already require this label. The Grocery Manufacturer’s Association (GMA), an industry trade group that represents a number of major food retailers including Pepsico Inc., The Coca Cola Company, Kelloggs, […]

(Beyond Pesticides, March 4, 2013) Two studies released on February 28th in the journal Science detail the dramatic decline of wild pollinators and their effectiveness in producing seeds and fruit on crops in comparison to domesticated honey bees. The study conducted on the effectiveness of wild pollinators, which was led by Lucas A. Garibaldi Sc.D. of Universidad Nacional de Río Negro in Argentina, collected data at 600 test fields on all continents except Antarctica for 41 crop systems. These studies come on the heels of a possible suspension of neonicotinoid insecticides, which have been linked to Colony Collapse Disorder (CCD), by states in the European Union. In the United States action currently looks less likely, as the U.S. Environmental Protection Agency (EPA) has moved to register sulfoxaflor, which the agency has classified as “very highly toxic to bees.” These studies note that even though large active colonies of honey bees are useful for pollination, they cannot fully replace the contributions of diverse, wild insects in plant pollinations. Dr. Garbaldi’s study calls for, among other policy recommendations, “consideration of pollinator safety as it relates to pesticide application.” The first of these two studies, led by Laura A. Burkle Ph.D., was titled […]

(Beyond Pesticides, February 28, 2013) Representative Jared Polis (D-CO) announced last Wednesday that he intends to co-sponsor a bill in Congress along with Representative Peter DeFazio (D-OR) to mandate the labeling of food containing genetically engineered (GE) ingredients in the U.S. Earlier this week, the Maryland House Health and Government Operations Committee held a public hearing on state House Bill 0903, which would set requirements for labeling and disclosure of genetically engineered ingredients in food.  Other state labeling efforts have been launched in California, Hawaii, New Mexico, Oregon, Missouri and Washington. More than 90 percent of Americans believe that foods with GE ingredients should be required to be labeled; however, Rep. Polis recognizes that it is still going to be tough to get enough votes to pass. Corporate opponents have spent tens of millions of dollars lobbying against GE labeling, and a bill introduced in the state of Colorado by Representative Jeanne Labuda (D-Denver) to label GE foods was stopped after just five hours of testimony. The House Health, Insurance and Environment Committee in Denver voted 7-2 against the bill just a day after Rep. Polis’ announcement. Despite testimony from concerned consumers, parents, and health advocates, the committee said the […]

(Beyond Pesticides, February 27, 2013) Last week a U.S. Court of Appeals found that pesticide restrictions to protect endangered salmon and steelhead proposed by the National Marine Fisheries Service (NMFS) in its Biological Opinion (BiOp) were “arbitrary and capricious,” supporting Dow AgroSciences LLC and other pesticide makers’ claims that the restrictions were based on “unsupported assumptions and conclusions.” The BiOp concluded that the pesticides chlorpyrifos, malathion and diazinon, three of the most highly toxic pesticides still in use, pose risks to salmon, steelhead and their habitat. In collaboration with NMFS, the U.S. Environmental Protection Agency (EPA) is tasked with implementation of any recommended pesticide restrictions to satisfy the mandate under Section 7 of the Endangered Species Act (ESA). However, to date, EPA has not taken any actions to implement any of the proposed measures to protect endangered salmon and steelhead, in part due to challenges from industry. Dow AgroScience LLC, Makhteshim Agan of North America, Inc., and Cheminova, Inc. USA first filed a suit in 2009 (Dow Agrosciences v. National Marine Fisheries ), challenging the NMFS’ 2008 BiOp to restrict  chlorpyrifos, malathion and diazinon as being based on numerous unsupported assumptions and conclusions, and faulty analyses. The U.S. District Court […]

(Beyond Pesticides, February 19, 2013) On February 14, Beyond Pesticides joined with Earthjustice, Farmworker Justice, and a number of other environmental and farmworker organizations to submit a letter to Environmental Protection Agency (EPA) Administrator Lisa Jackson, urging for long overdue revisions to the Workers Protection Standard (WPS) of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). The letter states that, “EPA’s inaction is unacceptable given farmworkers’ persistent exposure to harmful pesticides and ineffectual enforcement of the current WPS.” This letter comes after a previous petition in 2011 stressed the need for the agency to implement stronger protections for farmworkers. This letter also comes after fears from environmental and farmworker organizations over a recent EPA handout distributed during a November 2012 Pesticide Program Dialogue Committee (PPDC) meeting that downplayed the details of a 2010 EPA document released on farmworker safety. EPA has not effectively updated WPS for almost 20 years, leaving farmworkers at risk. Farm work is demanding and dangerous physical labor. A 2008 study by a National Institute for Occupational Safety and Health (NIOSH) researcher finds that the incidence rate of pesticide poisoning is extremely high among U.S. agricultural workers. An average of 57.6 out of every 100,000 agricultural workers […]

(Beyond Pesticides, February 14, 2013)   Beyond Pesticides’ 31st National Pesticide Forum brings together top national scientists with local and national activists and concerned citizens to share information on the issues local communities are facing, craft solutions and catalyze networks to advance positive health and environmental policy and change.

(Beyond Pesticides, February 13, 2013) After years of scrutiny and criticism, the U.S. Environmental Protection Agency’s (EPA) Administrator Lisa P. Jackson signed amendments strengthening existing standards for human research involving pesticides submitted by third parties for consideration in EPA decisionmaking. These amendments apply to studies involving the controlled exposure of participants to pesticides, with the hope that these “tougher” new standards will decrease the number of intentional human dosing studies conducted for pesticides. Even though EPA stated in 2001 that it will not consider or rely on human studies in its regulatory decisionmaking, subsequent industry pressure resulted in EPA invoking the Common Rule (40 CFR 26 – Protection of Human Subjects) for third-party intentional dosing studies. The agency promulgated new rules and made revisions to these rules, stemming from the lawsuit and settlement by the Natural Resources Defense Council (NRDC) et al., to broaden and refine rules relating to human research involving pesticides. In 2010, EPA published the proposed rule to amend EPA’s protocol for the testing of pesticides on humans. Now finalized, the rule strengthens EPA’s 2006 rule, Protections for Subjects in Human Research. Now prohibited is testing on nursing and pregnant women, children, as well as testing on […]

(Beyond Pesticides, February 12, 2013)   Is 2013 the year colony collapse disorder (CCD) begins impacting our food supply? According to the American Bee Journal, almond growers in California may not have access to the honey bee colonies necessary to pollinate this year’s crop. “We need 1.6 million colonies, or two colonies per acre, and California has only about 500,000 colonies that can be used for that purpose. We need to bring in a million more colonies but due to the winter losses, we may not have enough bees,” says Eric Mussen, PhD,  extension apiculturist at the University of California Davis (UC Davis) Department of Entomology. The problem, Dr. Mussen explains, is due to heavy losses this winter and less populous hives overall. Some beekeepers are reporting astonishing winter losses upwards of 90 percent, and in select cases complete colony loss. Honey production in 2012 was one of the worst years in the history of the United States, Dr. Mussen notes. Less honey means less food for overwintering bees, putting increased stress on colonies attempting to fight off the spread of CCD. CCD is the name given to the precipitous decline of honey bee populations around the world beginning in […]

(Beyond Pesticides, February 7, 2013) Despite passing the Senate Public Affairs Committee last week after an overwhelmingly positive discussion, Senate Bill 18 to amend the New Mexico Food Act, which would require the labeling of genetically engineered (GE) food and feed,  was “deemed lost” after a majority of the Senate, in an extremely rare action, voted on the Senate Floor not to adopt the committee’s report. Under Senate rules, this stopped the bill in its tracks and cut off any further debate or public input. “Even though SB 18 is dead this year, it’s clear that New Mexicans want and deserve a label that tells them whether or not their food has been genetically engineered,” said the bill’s author Senator Peter Wirth (D-25 Santa Fe). “I greatly appreciate the Public Affairs Committee’s feedback and discussion around the issue of labeling GE food, as well as Senate Majority Leader Michael Sanchez’s leadership on this issue. GE food labels are a right New Mexican consumers deserve and, while this defeat is a setback, this discussion will continue at the state and national level.” The bill passed the Public Affairs Committee five to three with Senators Craig Brandt (R-Dist 40), Ron Griggs (R-Dist […]

(Beyond Pesticides, February 6, 2013) The U.S. Environmental Protection Agency (EPA) has proposed to register a new insecticide, sulfoxaflor, which the agency has classified as “very highly toxic” to honey bees. Despite efforts underway in Europe to protect bee populations, and continued warnings from beekeepers, EPA is poised to allow another chemical toxic to bees into the environment without proper field studies evaluating long-term effects to bee colonies and with label statements that are impractical and unenforceable. With continuing reports of bee deaths, would sulfoxaflor be yet another bee disaster waiting to happen? Take action and tell EPA not to repeat past missteps and protect pollinators from sulfoxaflor by providing a public comment to EPA.   (see below for sample comments). Last month, EPA opened the comment period for the proposed conditional registration of sulfoxaflor, a new active ingredient, whose mode of action is similar to that of neonicotinoid pesticides -it acts on the nicotinic acetylcholine receptor (nAChR) in insects. Even though it has not been classified as a neonicotinoid, it elicits similar neurological responses in honey bees, with many believing that sulfoxaflor is the new generation of neonicotinoid.  EPA has noted that sulfoxaflor is highly toxic to bees, and […]

(Beyond Pesticides, February 5, 2013) Although nanoparticles are increasingly added to a wide range of consumer products, very little is known about the potential risks these materials pose to the health of our environment. A study by the Dutch research institute Alterra looked at the effects of nanoparticles on earthworms, revealing the ability of nanomaterials to cause significant harm to the beneficial organisms. Earthworms are excellent indicators of soil health, and provide vitally important ecosystem services by aerating the soil, cycling nutrients, and increasing microbial activity. The Alterra study, led by Doctoral candidate Merel van der Ploeg, compared the health and growth of earthworms in soil containing carbon and silver nanoparticles at varying amounts with worms in regular soil. Mr. Van der Ploeg found the soil containing nanoparticles reduced reproduction, slowed growth, and increased the mortality rate of exposed earthworms. Young worms are particularly sensitive to the effects of the nanomaterial. Mr. Van der Ploeg notes, “I also found damage to the skin tissue and intestinal wall, often accompanied by damage to the underlying muscle, but even though tissue damage is usually associated with inflammation, I did not observe this in the earthworms. There seemed to be a suppression of […]

(Beyond Pesticides, February 4, 2013) U.S. Senators Pat Roberts (R-KS) and Mike Johanns (R-NE) re-introduced legislation that would reduce the review requirements for pesticides applied directly to water. Similar legislation was passed in the House of Representatives in March 2011. The previous Senate version of the bill, called the Reducing Regulatory Burdens Act of 2011, passed through the Senate Agriculture Committee but never reached the Senate floor because of a hold placed on the legislation by Senators Barbra Boxer (D-CA) and Benjamin L. Cardin (D-MD). This re-introduced legislation would reduce pesticide testing by ensuring that Clean Water Act (CWA) permits are not required for the application of pesticides. In 2009, the 6th Circuit Court of Appeals ruled in the case of the National Cotton Council et al. v. EPA that pesticides discharged into water are pollutants and required to be permitted under the CWA’s National Pollutant Discharge Elimination System (NPDES). This ruling overturned Bush administration policy that exempted pesticides from regulation under the CWA and applied the less protective standards of the Federal Insecticide Fungicide and Rodenticide Act (FIFRA). CWA uses a health-based standard known as maximum contamination levels (MCLs) to protect waterways and requires permits when chemicals are directly […]

(Beyond Pesticides, January 30, 2013) A new report, “Late lessons from early warnings: science, precaution, innovation,” from the European Environment Agency (EEA) concludes that concerns raised by the scientific community on bee death, genetically engineered (GE) food, and nanotechnology support the need for a precautionary approach to public policy. Significantly, the report concludes that the “precautionary principle,” whereby industry and policy makers are advised to take seriously  early warnings about potential environmental impacts is “nearly always beneficial.” The report cites some industry efforts to undermine precautionary decision making. The report features case studies on environmental impacts, such as mercury poisoning, effects on fertility caused by pesticides, and the impact of pharmaceuticals on some ecosystems, and raises questions about the potential wider impacts of GE crops, nanotechnology, nuclear power, and the effect of pesticides on bee populations. The report lays the blame for numerous environmental crises squarely at the feet of corporations and policy makers who ignore early warnings about environmental impacts. “The historical case studies show that warnings were ignored or sidelined until damage to health and the environment was inevitable,” the EEA said. “In some instances, companies put short-term profits ahead of public safety, either hiding or ignoring the […]

(Beyond Pesticides, January 29, 2013) A new study has discovered the anti-bacterial chemical triclosan and several of its toxic derivatives in sediment samples taken from freshwater lakes. Research published in the journal Environmental Science and Technology reveals the chemical to be present in increasing concentrations since it was first invented in the 1960’s. The results of this study put increased pressure on lawmakers and cosmetic companies to remove this chemical from consumer products. Beyond Pesticides and other groups, which have petitioned the U.S. Food and Drug Administration (FDA) and the U.S. Environmental Protection Agency (EPA) to remove triclosan from a vast array of consumer products, continues to urge cosmetic companies to take action on the chemical in the face of inadequate regulation to protect human health and the environment. Scientists tested  eight sediment samples from freshwater lakes across Minnesota, including Lake Superior. Bill Arnold, Ph.D.,  co-author of the study and professor at University of Minnesota notes, “We found that in all the lakes there’s triclosan in the sediment, and in general, the concentration increased from when triclosan was invented in 1964 to present day. And we also found there are seven other compounds that are derivatives or degradation products of […]

(Beyond Pesticides, January 28, 2013) Research published Thursday indicates that pesticides widely used on farms are highly toxic to frogs. Researcher Carsten Brühl, Ph.D., at the University of Koblenz-Landau in Germany called the results “alarming” with the potential for “large-scale effects” on amphibians. Two chemicals commonly used in orchards and on grains demonstrated a 100% mortality rate when researchers applied doses recommended on the label, raising serious concerns about the strength of pesticide regulations. The research builds on Brühl’s previous work on the ability of frogs to absorb pesticides through their porous skin, which is necessary for breathing underwater. More importantly, the study highlights the threats that pesticides post to biodiversity. Amphibians are considered the most threatened and rapidly declining vertebrate group, with more than a third of all amphibians listed in the International Union for Conservation of Nature and Natural Resources (IUCN) “Red List” of threatened species. The organization lists loss of habitat, climate change, and disease as the most serious threats to amphibian populations. The scientific community is increasingly recognizing the role of chemical pollutants in amphibian decline. Though sadly, regulatory agencies do not: pesticides are not even required to be tested on amphibians before the pesticide is […]

(Beyond Pesticides, January 25, 2013) The U.S. Environmental Protection Agency (EPA) has  concluded that corn rootworm is now resistant to genetically engineered corn infused with a toxin derived from Bacillus thuringiensis, or Bt, in certain parts of the Corn Belt, casting doubt on the future viability of GE corn. The conclusion of the Insect Resistance Management (IRM) Team is based on several years of data indicating that the Cry3Bb1 protein strain of Bt is ineffective at controlling corn rootworm. The press release on January 17 states: “The EPA IRM Team has concluded that corn rootworm may not be completely controlled by Cry3Bb1 in certain parts of the Corn Belt. While ”˜confirmed resistance’ as defined in registration documents has not been met, given the nature of the data, the manufacturer, Monsanto, has agreed to several actions and changes related to the registration of Cry3Bb1 products to address these matters.” Originally marketed by Monsanto in 2003, the protein Cry3Bb1 is designed to destroy the gut of the western corn rootworm. The rootworm has historically devastated corn fields, causing greatest damage in chemical-intensive agriculture during its larval stage by feeding upon the plant’s roots, inhibiting the plant’s ability to absorb moisture and nutrients […]

(Beyond Pesticides, January 23, 2013) A new federal report finds toxic contamination remains widespread in the Chesapeake Bay, with severe impacts in some places, which health and environmental advocates say lends support to their push in Maryland for legislative action on pesticides and other hazardous chemicals. In spite of some cleanup, the health of the Bay has not significantly improved. The report, “Technical Report on Toxic Contaminants in the Chesapeake Bay and its Watershed: Extent and Severity of Occurrence and Potential Biological Effects” is based on a review of integrated water-quality assessment reports from the jurisdictions in the Bay watershed (Delaware, Maryland, New York, Pennsylvania, Virginia, West Virginia, and Washington, D.C.), Federal and State reports, and articles in scientific journals. It notes that nearly three-fourths of the Bay’s tidal waters are “fully or partially impaired” by toxic chemicals, with people warned to limit fish consumption from certain areas. Contamination is severe in a handful of “hot spots” around the Bay, including Baltimore’s harbor, largely a legacy of past industrial and shipping activity. Previous reports have called on federal, state and local government to accelerate research into what threats chemical contamination may pose to the Bay, and to step up efforts […]

(Beyond Pesticides, January 18, 2013) Joining the list  of speakers at Beyond Pesticides’ 31st National Pesticide Forum are Tyrone Hayes, Ph.D., the biologist best known for his research on the effects of atrazine on frogs, and Isaac N. Pessah, Ph.D., the  Chair of the Department of Molecular Biosciences at the University of California, Davis School of Veterinary Medicine. The conference will focus on cutting edge public health science, building resilience in our food system and communities, and bringing ecosystems back to balance, and will incorporate regional issues such as water and food sovereignty in the Southwest. The National Forum provides an opportunity for grassroots advocates, scientists, and policy makers to interact and strategize on solutions that are protective of health and the environment. The 31st National Pesticide Forum, Sustainable Families, Farms and Food: Resilient communities through organic practices, will be held April 5-6, 2013 (Friday afternoon and all day Saturday) at the University of New Mexico in Albuquerque, NM.

(Beyond Pesticides, January 16, 2013) Children living near chemical-intensive or conventional plantations in Costa Rica are exposed to twice as much of the insecticide chlorpyrifos compared to children living near organic plantations, a study reports. More than half the children, mostly from indigenous tribes- Ngäbe and Bribri – have a  higher daily exposures than allowed under U.S. federal standards. Chlorpyrifos is linked to neurological effects, especially in children, and is still permitted for use on crops. The study,  Indigenous children living nearby plantations with chlorpyrifos-treated bags have elevated 3,5,6-trichloro-2-pyridinol (TCPy) urinary concentrations, was lead by Berna van Wendel de Joode, PhD  (Central American Institute for Studies on Toxic Substances (IRET), Universidad Nacional, Heredia, Costa Rica). It was conducted in Costa Rica’s banana and plantain plantations in the Talamanca region, and  targeted villages situated nearby to the plantations where blue bags treated with chlorpyrifos are routinely used to protect banana and plantain crops from pests. Two villages under study are near plantations that use chlorpyrifos-treated bags, while the organic village is near several plantations  that use little or no insecticide. For 140 children, aged 6 — 9, mostly indigenous Ngäbe and Bribri, parent-interviews and urine samples were obtained. Chlorpyrifos’ environmental levels […]

(Beyond Pesticides, January 15, 2013)  Research published in the journal Environmental Monitoring and Assessment calls into question the value of environmental monitoring, such as water sampling,  on a  fixed date schedule (i.e., once per month), finding that this approach underestimates actual risks. These findings could have a significant impact on how we assess the safety of both endangered species and drinking water supplies. Researchers explain that, although insecticides are applied less often than herbicides and fungicides, they are usually applied in very large amounts when used in response to acute insect infestations. Scientists found that monitoring for insecticides at pre-set intervals, even weekly or daily, did not detect the occurrence of peak concentrations for these chemicals. Co-author of the study, Ralf Shulz, PhD, explains, “Accordingly, by way of example, on the basis of weekly monitoring of a typical agricultural stream none of the total of six insecticide concentration peaks per year described by model calculations is found. Daily sampling detects only two of the six peaks. Only event-related sampling enables the detection of all these peaks.” Authors of the study point to the need for events-related sampling, both to ensure more accurate detections are taken and to reduce costs. Events-related […]
