(Beyond Pesticides, August 26, 2011) The U.S. Department of Agriculture (USDA) has announced that it will hold a free public listening session on the department’s activities related to organic food and farming in order to gather input from farmers, consumers, and other interested parties regarding a wide range of subjects. The agency is hoping to gather more feedback and guidance from stakeholders in the world of organic food and agriculture in order to “help USDA programs examine and prioritize their activities and objectives in order to best serve the organic community.” The scope of matters on which USDA is hoping to hear comments is very broad and seemingly includes any of the department’s actions which could potentially impact organic growing practices or organic producers. The announcement for the listening session outlined two general areas on which comments can be submitted. The first concerns any activities of the National Organic Program (NOP) that do not relate to matters likely to come before the National Organic Standards Board (NOSB). Since the NOSB has its own process for soliciting and reviewing public comments at its biannual meetings, NOP is seeking comments on actions that it takes which are independent of the NOSB. These […]

(Beyond Pesticides, August 24, 2011) Scientists say the fungus that causes apple scab appears to be growing more resistant to pesticides routinely used to control the fungus, worsening the threat of outbreaks in commercial orchards. For decades, manufacturers have come up with replacements for chemical mixtures the fungus outwitted. By using a rotating lineup of fungicides from year to year, farmers usually stayed a step ahead of the scab. But the fungus now appears to be overcoming multiple fungicides at once. In a paper published this month in the journal Plant Disease, researchers described samples collected in Indiana and Michigan that are resisting all four of the most commonly used chemical treatments: dodine, kresoxim-methyl, myclobutanil, and thiophanate-methyl. “We’ve dealt with fungicide resistance over the years, but this time we’re losing three or four different classes of completely unrelated fungicides at the same time,” said Henry Ngugi, PhD, a plant pathologist with Penn State University’s Fruit Research and Extension Center. “We have to literally go back to the drawing board.” Another ominous sign: The fungus apparently hasn’t developed any new weaknesses while evolving to resist the pesticides, unlike what usually happens in nature, the study found. Anecdotal reports from orchard owners […]

(Beyond Pesticides, August 23, 2011) It’s that time of the year again for kids to return to the classroom. Unfortunately, children may face unexpected dangers from pesticides, including antibacterial chemicals, used in and around schools. Studies show pesticides can impact a child’s neurological, respiratory, immune, and hormone systems, even at low levels. Help create a healthier and safer school environment by checking the following items off your Back to School Checklist. 1. Get Triclosan Out of Schools and Supplies. The antibacterial chemical triclosan is linked to skin irritation, hormone disruption, antibiotic resistance, and more. Avoid products labeled Microban or “with antibacterial protection” as they may contain triclosan (product list). Ask your school to order triclosan-free soap and school supplies. See Back to School flyer. Take Action: Bath & Body Works has marketed an entire line of triclosan-containing body care products to teenagers. Tell Bath & Body Works’ CEO: “Stop using toxic triclosan in your products.” 2. Improve Your School’s IPM Program. Children face unique hazards from pesticide exposure because of their small size and developing organ systems. A strong integrated pest management (IPM) program is one of the best ways to minimize or eliminate children’s exposure to pesticides. See how […]

(Beyond Pesticides, August 15, 2011) Poultry farms that have adopted organic practices and cease using antibiotics have significantly lower levels of drug-resistant enterococci bacteria that can potentially spread to humans, according to a new study published August 10, 2011 in the online edition of Environmental Health Perspectives. The study, led by researchers at the University of Maryland’s School of Public Health, suggests that organic conversion of U.S. poultry farms can result in immediate and significant reductions in antibiotic resistance for some bacteria. The non-therapeutic use of antibiotics in livestock production accounts for nearly 80% of all antibiotics used in the United States. Typically, low levels of antibiotics are administered to animals through feed and water to prevent disease and promote growth. This is generally done to compensate for overcrowded and unsanitary living conditions, as is common in concentrated animal feeding operations (CAFOs), and to fatten livestock to get them to market sooner. Antibiotic use is prohibited in the production of all animal products labeled organic. “We initially thought we would see some differences in on-farm levels of antibiotic-resistant enterococci when poultry farms transitioned to organic practices. But we were surprised to see that the differences were so significant across several […]

(Beyond Pesticides, August 3, 2011) Despite the continued sluggish economic recovery, U.S. retail sales of natural and organic foods and beverages rose to nearly $39 billion in 2010, according to a new report available on companiesandmarkets.com. This is an increase of 9% over the previous year’s sales of $35 billion, far outpacing growth in conventional groceries, which crept ahead less than 2%. Organic sales are projected to more than double by 2015, to exceed $78 billion. [Confused about Natural vs Organic? They are not the same. Learn more about why organic is the right choice. Read Beyond Pesticides’ factsheet “Making Sure Green Consumer Claims Are Truthful”] The report, “Natural and Organic Foods and Beverages in the U.S., 3rd Edition,” examines sales and growth potential, identifying key issues and trends that will affect the marketplace through 2015, and analyses consumer attitudes and behaviors toward natural/organic foods and beverages. Organic sales also had a great performance in 2008 with U.S. sales reaching $24.6 billion by the end of 2008, growing an impressive 17.1 percent over 2007 sales. Organic food sales accounted for approximately 3.5 percent of all food product sales in 2008. A recent poll by Thomson Reuters and National Public Radio […]

(Beyond Pesticides, July 27, 2011) A recent poll conducted by Thomson Reuters and National Public Radio (NPR) shows that a majority of Americans prefer to buy organic food when given the chance. In the survey, 58% of respondents say they choose organic over conventionally produced foods when they have the opportunity, a number that spikes higher among both young and highly educated respondents. 63% of respondents under the age of 35 prefer organic foods, as do 64% of those with a bachelor’s degree or more. Desire for organic food was relatively even across income brackets, as 59% of those making between $50,000 and $100,000 a year preferred organic, as did 56% of those making less than $25,000 a year. Preference for organic food was at 61% for those whose annual income was $25,000-$50,000 as well as more than $100,000. The survey asked five questions of respondents: (1) Given a choice, would you prefer to eat organic or non-organic foods? (2) What are your reasons for preferring organic food? (3) What are your reasons for preferring non-organic food? (4) Given a choice, where would you most prefer to get your produce? (5) In a restaurant, would your ordering decision be influenced […]

(Beyond Pesticides, July 26, 2011) On July 25, 2011, in the case of Oluf Johnson v. Paynesville Farmers Union Cooperative Oil Company, Judge Ross of the Minnesota Court of Appeals ruled that pesticides drifting from one farm to another may constitute trespass. Organic farmers Oluf and Debra Johnson filed a civil suit alleging that the oil company sprayed a pesticide that drifted from targeted fields onto theirs, and that this prevented them from selling their crops as organic. Previously, a district court dismissed the Johnsons’ trespass claims. The victory is important for organic growers who are frequently under threat of pesticide drift from neighboring properties. Under the federal organic standards authorized by the Organic Foods Production Act (OFPA), produce may not be labeled organic if it is contaminated with pesticide residues, as a result of off-site use, o greater than five percent of the allowable pesticide tolerance levels. Pesticide tolerances are the pesticide residue limits used in the U.S. or by countries imporing to the U.S., which are set by the federal government under the Food Quality Protection Act (FQPA). Because we live in a polluted world where pesticide residues are present, often at low levels, nearly everywhere. A very […]

(Beyond Pesticides, July 12, 2011) Following the Environmental Protection Agency’s (EPA) denial of Dow AgroSciences’ request for an administrative hearing to keep sulfuryl fluoride on the market, the Natural Resources Defense Council (NRDC) sent a letter to the agency on June 29, 2011 opposing EPA’s phase-out of the toxic fumigant pesticide, which is marketed as a substitute for the outdated, ozone-depleting methyl bromide. According to its letter, the environmental group believes that the “proposed action will imperil EPA’s ability to complete the long-overdue phase-out of methyl bromide, leading to prolonged and increased depletion of the ozone layer, higher levels of ultraviolet radiation, and higher risks of cancer, cataracts, and immunological disorders.” Under pressure from a 2006 petition submitted by Fluoride Action Network (FAN), Beyond Pesticides, and Environmental Working Group (EWG), EPA announced its plan to cancel all allowable pesticide residue levels (tolerances) for sulfuryl fluoride over three years, effectively banning its use in January 2014. The agency found that when residues on food products are combined with fluoridated drinking water and toothpaste, aggregate exposure levels are too high. Beyond Pesticides has repeatedly pointed to non-toxic practices that have eliminated the need for either hazardous fumigant throughout the process. Manufactured by […]

(Beyond Pesticides, July 6, 2011) After 27 years of fighting invasive weeds without the high-powered help of toxic chemicals, the Eugene district of the U.S. Bureau of Land Management (BLM) wants to add herbicides back into the toolkit. Eugene district BLM officials are proposing to use four herbicides to kill weeds along roadsides and in rights-of-way. The BLM stopped using herbicides in Oregon in 1984 after a court injunction in response to a lawsuit filed by the Northwest Coalition for Alternatives to Pesticides. The coalition had argued that the agency had not followed federal procedures in approving the use of herbicides on public lands, and a judge agreed. The BLM eventually wrote an environmental impact statement (EIS) on its proposal to use herbicides, but a final management plan wasn’t completed until last year. The BLM said it will only be doing ground application and not spraying herbicides by helicopter or plane. The management plan permits the agency to use 17 different herbicides to control weeds but only in limited circumstances. Now individual districts, including Eugene, are developing site-specific proposals for using chemicals. Locally, four herbicides are under consideration. Glyphosate, imazapyr, triclopyr, and clopyralid are effective on a range of plants, […]

(Beyond Pesticides, July 1, 2011) The U.S. Environmental Protection Agency (EPA) has granted emergency approval for the use of the neonicotinoid pesticide dinotefuran to control brown marmorated stink bugs in seven eastern states. Dinotefuran is a member of the neonicotinoid family of systemic pesticides that is known to be highly toxic to bees and associated with Colony Collapse Disorder. The states of Delaware, Maryland, New Jersey, North Carolina, Pennsylvania, Virginia, and West Virginia had previously asked EPA for emergency approval of the pesticide due to a ballooning stink bug population. The short term emergency measure became effective June 24 and will expire on October 15 of this year. Dinotefuran is already approved by EPA for use on other crops, such as grapes, cotton, and some vegetables. The emergency approval relates to the pesticide’s use on orchard crops such as apples, pears, peaches, and nectarines, for which it has not previously been allowed. Growers of those crops will now be able to apply dinotefuran from the ground twice per season. The agency will allow a total of 29,000 orchard acres to be treated, which does not include applications to the previously approved crops. Under a controversial stipulation known as a Section […]

(Beyond Pesticides, June 23, 2011) The Senate Agriculture Committee has passed legislation that would allow pesticides to be sprayed into water without a Clean Water Act (CWA) on Tuesday, June 21, and urgent action is needed to stop the bill from passing in the full Senate. The bill, Reducing Regulatory Burdens Act of 2011 (H.R. 872) amends the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA) and the CWA, reversing a 2009 court order requiring the permits as a part of the National Pollutant Discharge System (NPDES). The U.S. House of Representatives already passed H.R. 827 by a vote of 292-130 back in April. Beyond Pesticides encourages individuals and organizations email and call their Senators that regulating pesticides under the CWA is necessary to protect our waterways, public health, fish, and wildlife, and therefore, they must oppose H.R. 872. Out of eight committee members who voted, the only ones to oppose the bill were Sen. Patrick Leahy (D-Vt.) and Kirsten Gillibrand (D-N.Y.), who was not present at the markup, but issued a recorded vote. Without press or notice, the bill was marked up private business meetings, and is being heralded by the National Corn Growers Association (NCGA), which states that “The […]

(Beyond Pesticides, June 22, 2011) Exposure to two herbicides, atrazine and 2,4-D, commonly used in lawn care and forest management will be studied by Oregon health officials after they were found in the urine of residents of the Triangle Lake area of the Coast Range west of Eugene, Oregon. The State Department of Agriculture is directing health officials who are part of the state’s Pesticide Analytical Response Center to take the lead in studying the matter. Triangle Lake area residents and a group of activists called the Pitchfork Rebellion have been complaining for more than seven years about the possibility that herbicides being aerially sprayed on nearby private forests may be drifting onto their land. The group in the past has asked the state to investigate their concerns, staging rallies and protests, and attending meetings of government agencies, including the pesticide response board and the Oregon Board of Forestry. At an April 2011 meeting of the forestry board, when the group presented proof of chemical exposure, the state agreed to take a closer look. The board regulates logging and related practices on private timberlands in Oregon. At that meeting, Dana Barr, PhD, a research professor at Emory University’s Environmental and […]

(Beyond Pesticides, June 15, 2011) This week’s release of the new Shopper’s Guide to Pesticides in Produce (Dirty Dozen/Clean 15) by the Environmental Working Group (EWG), which focuses on pesticide residues on conventional produce, highlights the importance of eating organic fruits and vegetables to minimize personal exposure to toxic pesticides. Beyond Pesticides’ Eating with a Conscience guide complements the EWG list, going beyond residues on food to examine the impacts of the pesticides used to grow conventional produce on the health of farmworkers and rural communities, water quality, honey bees and wildlife poisoning, and more. Both Beyond Pesticides and EWG encourage shoppers to choose organic food whenever possible. To create their seventh edition of the Shopper’s Guide, analysts at EWG synthesized data collected from the U.S. Department of Agriculture (USDA) and the Food and Drug Administration (FDA). Most samples are washed and peeled prior to being tested, so the rankings reflect the amounts of the chemicals likely present on the food when is it eaten. Apples, celery and strawberries top this year’s “Dirty Dozen” list. Making an appearance in the guide for the first time is the herb cilantro, which had never been tested by USDA until now. The data […]

(Beyond Pesticides, June 10, 2011) A report released jointly by the U.S. Department of Agriculture’s (USDA) Agricultural Research Service (ARS) and the Apiary Inspectors of America (AIA) shows that losses of honeybee populations over the 2010/2011 winter remained abnormally high, reflecting continuing damages attributed to colony collapse disorder (CCD). CCD, linked to a range of factors and agricultural chemicals, including systemic pesticides, has devastated bees and beekeepers around the country in recent years. According to the survey, 30% of managed honeybee colonies across the country were lost over the winter. Over the past five years, since the discovery of CCD, annual winter colony losses have hovered near the 30% mark. Similar loss percentages for the previous four years reflect this trend: 34% for the 2009/2010 winter, 29% for 2008/2009, 36% for 2007/2008, and 32% for 2006/2007. ARS entomologist Jeffrey Pettis, PhD, who helped to conduct the survey and has been the agency’s lead researcher on CCD heading up the USDA Bee Research Laboratory, said, “The lack of increase in losses is marginally encouraging in the sense that the problem does not appear to be getting worse for honey bees and beekeepers. But continued losses of this size put tremendous pressure […]

(Beyond Pesticides, May 20, 2011) At its April 26-29, 2011 Spring meeting in Seattle, Washington, the National Organic Standards Board (NOSB) strengthened standards affecting the integrity of organic food and farming and rejected proposals that would have weakened the standards. The board voted on recommendations proposed by each of the various issue committees including Crops; Livestock; Handling; Materials; Certification, Accreditation, and Compliance; and Policy Development. Decisions were made regarding a wide range of materials and practices, from pesticides and fertilizers to mulches and processing aids. There were several highly controversial issues discussed, including the use of antibiotics to control fruit tree diseases, living conditions for livestock, and the process for how the board determines whether a material is natural or synthetic. You can find details for the meeting on Beyond Pesticides’ organic action page. Prior to the meeting, the committee proposals were posted on the internet and opened for public comment. Following the democratic spirit inherent in the organic law, the board is required to take the voiced concerns of the public into consideration in making its decisions. There were over three thousand comments submitted to the board for this meeting — more than any other previous NOSB meeting. Many […]

(Beyond Pesticides, May 13, 2011) Two recent studies performed independently of each other confirm that organically produced food is safer and can actually save money in the long term. A report from the University of Florida has found that salmonella is the leading disease-causing pathogen found in food, leading to more than $3 billion every year in public health costs. Salmonella is a microbe that is often found in poultry and egg products. An unrelated study, published in November of last year by the University of Georgia, found that there is a significantly lower rate of salmonella contamination in organic chickens compared to conventional chickens. Taken together, the results of these two studies reveal the potential for organic poultry farming to significantly reduce the risk to human health from food pathogens, as well as the cost to society of treating and eliminating those pathogens. In April of this year, the Emerging Pathogens Institute at the University of Florida released a report entitled “Ranking the Risks: The 10 Pathogen-Food Combinations with the Greatest Burden on Public Health.” The aim of the report was to evaluate the burden to society, in terms of health risks as well as financial cost, caused by […]

(Beyond Pesticides, May 12, 2011) Beyond Pesticides joined 112 organizations in endorsing a 102-page set of environmental right-to-know recommendations, which OMB Watch presented on Tuesday, May 10 to the Obama administration. The recommendations, collaboratively drafted by advocates from across the country, aim to expand access to environmental information, equip citizens with data about their environmental health, and empower Americans to protect themselves, their families, and their communities from toxic pollution. The recommendations are contained within a report titled An Agenda to Strengthen Our Right to Know: Empowering Citizens with Environmental, Health, and Safety Information, drafted as part of the Environmental Information Initiative project. OMB Watch compiled the report following a year of work that culminated in a conference of almost 100 environmental, health, and safety advocates held in November 2010. Sean Moulton, OMB Watch’s Director of Federal Information Policy, said, “Many of the recommendations laid out in the report are ambitious, but they are also needed. Environmental and right-to-know advocates believe that much more information, presented in more searchable and usable formats, is necessary in order to adequately protect Americans’ environmental health.” Three key priorities are woven throughout the recommendations: 1. Environmental justice must always be considered — Minority and […]

(Beyond Pesticides, May 9, 2011) The Endocrine Disruptor Exchange Inc. (TEDX), founded by Theo Colborn, PhD, has released a list of chemicals with the potential to affect the endocrine system. According to TEDX, every chemical on the TEDX List has one or more verified citations to published, accessible, primary scientific research demonstrating effects on the endocrine system. Endocrine disruptors are chemicals that impact traditional endocrine glands, their hormones and receptors such as estrogens, anti-androgens, and thyroid hormones. To date there are approximately 800 endocrine disruptors on the TEDX List. Download the TEDX List (Excel) Many everyday chemicals that people are exposed to can wreak havoc on the body’s endocrine system. Pesticides such as triclosan, atrazine, permethrin and many others have been associated with effects on the body’s hormone system. Visit the Pesticide Induced Disease Database for more on the chemicals linked to endocrine disruption. Endocrine effects include direct effects on traditional endocrine glands, their hormones and receptors such as estrogens, anti-androgens, and thyroid hormones, as well as signaling cascades that affect many of the body’s systems, including reproductive function and fetal development, the nervous system and behavior, the immune and metabolic systems, the liver, bones and many other organs, glands […]

(Beyond Pesticides, May 6, 2011) On Wednesday this week, the Future of Food conference, organized by The Washington Post, convened at Georgetown University in Washington, DC and featured experts in science, industry, and agriculture discussing ways to reform local, national, and global food systems to work toward justice and sustainability. The keynote speaker for the conference was Prince Charles, Prince of Wales, who has been a longtime advocate for the natural world and for sustainable systems of food production. The event also featured such noted speakers as U.S. Secretary of Agriculture Tom Vilsack, global sustainability advocate Vandana Shiva, nutritionist Marion Nestle, writer Wendell Berry, urban agriculture pioneer Will Allen, organic researcher Fred Kirschenmann, author Eric Schlosser, Stonyfield CEO Gary Hirshberg, and many more. Prince Charles in his speech (text available here, video available here) discussed many of the problems currently facing food production and advocated for a swifter and more direct move toward more sustainable, or “durable,” as he called it, systems. Pointing out the many dangers caused by an industrial farming system that depletes natural resources and impairs biodiversity, he argued that we cannot afford to continue operating under the current system for very much longer before it starts […]

(Beyond Pesticides, May 5, 2011) Over 70 international organizations, including health and environmental groups, landscapers and farmers are proclaiming tomorrow, Friday, May 6, 2011, Lawn Pesticide Awareness Day in honor of Dr. June Irwin’s leading role in passage of North America’s first lawn pesticide ban in Hudson, Quebec, on May 6, 1991. “The town of Hudson, Quebec, and particularly the actions of June Irwin, M.D., have sent a clear signal to communities all across North America that the use of lawn and landscape pesticides is both harmful and unnecessary,” said Jay Feldman, the founder of Beyond Pesticides of Washington, D.C. “Chemical lawn pesticides are scientifically linked to cancer in people and pets, and are known to be toxic to the nervous and immune system, endocrine disruptors, and tied to respiratory effects such as asthma. Alternative practices that rely on maintenance techniques and soil health that prevent unwanted insect and weeds are far more effective than their chemical counterparts.” Now, for 80 percent of Canadians and a growing number of Americans, synthetic chemical lawn pesticides are becoming a habit of the past. In 1991, exactly six years from the first day she voiced her concerns at a town meeting, May 6, […]

(Beyond Pesticides, May 4, 2011) According to a U.S. Environmental Protection Agency (EPA) internal review of pesticide registrations under special circumstances, also known as “conditional registration,” the agency may reduce its use of this “imprecise” category, whilch allows widespread use of toxic chemicals not fully tested. Conditional registration of pesticides allows market entry for a product in the absence of certain data. Recent reports have found that certain conditionally registered pesticides known to be hazardous to pollinators were allowed to used by EPA without a full data set. In an April 25, 2011 post on its website, EPA provides details on its recently completed internal review on the use of conditional registration for pesticide products. The agency has come under scrutiny recently since it was revealed that the conditionally registered pesticide, clothianidin, did not at the time it allowed the pesticide to be widely used have pertinent field data required on honeybees, even though the pesticide is known to pose risks to these vulnerable pollinators. This data is still outstanding even though clothianidin continues to be used in the environment. Conditional registration is allowed under Section 3(c)(7) of the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA), whilch allows pesticide registration […]

(Beyond Pesticides, April 21, 2011) Citing consumer’s growing aversion to the toxic chemical DEET and other harmful pesticides, researchers at the Centers for Disease Control and Prevention (CDC) are pushing to develop a new natural repellent and insecticide from the chemical nootkatone, found in grapefruits. Nootkatone is derived from the essential oils of plants, including grapefruit, vetiver grass and Alaskan yellow cedar. As an essential oil, it is highly volatile and evaporates quickly. This means that it doesn’t last very long and may need to be applied frequently. As a result, researchers are seeking ways to make it longer-lasting. In one cooperative project by the CDC and the U.S. Department of Agriculture’s (USDA) Agricultural Research Service (ARS), entomologists Kirby Stafford, PhD and Robert Behle, PhD use lignin to encapsulate nootkatone in order to extend the chemical’s residual activity. The study, “Lignin + Nootkatone = Dead Ticks” published in the January 2011 issue of Agricultural Research magazine. Researcher Marc Dolan, PhD of the CDC’s vector-borne infectious diseases laboratory in Fort Collins, Colorado stresses nootkatone’s safety: “If you’ve had a grapefruit, you’ve consumed some nootkatone,” he said to NPR’s Morning Edition. “Essential oils [such as nootkatone] kill bugs and then break down […]
