Fight Against “Organic” Seafood Mislabeling Continues

(Beyond Pesticides, May 9, 2008) The Center for Food Safety (CFS) yesterday sent letters to the Attorneys General of 49 states urging the top state law enforcement officials to take action against the misleading practice of labeling seafood imports as “organic.” The state-based effort to protect the integrity of organic food labels is a follow-up to the complaints filed by the Center last year with the USDA and Federal Trade Commission (see also Daily News of November 5, 2007). To date, these federal agencies have left the complaints unanswered, while U.S. consumers are increasingly confronted with imported seafood misleadingly labeled as “organic,” despite the fact that there are no U.S. organic seafood standards in place. In the action, the CFS calls upon USDA to prevent consumer deception by enforcing existing organic labeling laws and regulations until new standards are finalized. CFS, which is joined in this effort by Food & Water Watch, has identified the practice of allowing seafood to be labeled as “organic” in absence of regulations as unfair, deceptive and misleading – a violation of the states’ consumer deception and misrepresentation laws. With U.S. sales of organic food dramatically increasing, a number of foreign seafood imports labeled as “organic” have appeared to take advantage of this emerging market.

“Allowing importers to label their seafood ‘organic’ when it does not have to meet any U.S. standards is a disservice to American consumers, who have come to trust and believe in the organic label,” said Joseph Mendelson, Legal Director of CFS. “USDA’s refusal to stop importers from calling their products organic when many of them use antibiotics, parasiticides, or feed that would not be permitted under U.S. regulations is dishonest. Consumers have the right to know that the labeling on their food is truthful and accurate and we’re asking the states to protect that right.”

USDA is currently in the process of establishing organic regulations for finfish and shellfish, a process that may take up to two years. In the middle of May, the National Organic Standards Board will be discussing new recommendations addressing the type of feeds that may be used under future organic aquaculture standards. As currently drafted, the regulations would not allow the use of antibiotics or non-organic feed. Antibiotics are a particular concern for both farmed and wild fish. Recently, salmon in New Zealand have been found to have four times the levels of antibiotics allowed by the country’s Food Standards. Salmon on the United States’ west coast are the subject of a recent lawsuit concerning their risk of pesticide exposure.

“It is time for other states to follow California’s example and stop the abuse of the organic label on imported seafood,” said Wenonah Hauter, executive director of Food & Water Watch. “Importers should not be allowed to market their products with claims about meeting a standard that doesn’t exist.”

In 2005, California passed a law (SB 730) preventing the labeling of any seafood as “organic” until federal standards are finalized and in place. With their letters, the Center for Food Safety and Food & Water Watch have requested that the nation’s 49 other states use their authority under existing consumer protection laws to quickly curtail the misleading use of the term “organic” by overseas seafood producers so that consumers are not adversely affected.

The integrity of the term “organic” is critical to protect consumers and farmers who are following USDA requirements. For more information on organic food farming, visit our program page.

Melting Glaciers Source of Persistent Pollutants

(Beyond Pesticides, May 8, 2008) New research shows that melting Antarctic glaciers are releasing once frozen stores of persistent organic chemicals, now banned in many parts of the world. Marine biologist, Heidi Geisz, a Ph.D. student at the Virginia Institute of Marine Science studying the fate and effect of organic contaminants in the Antarctic, has found that DDT concentrations in penguins has remained at the same levels as they were 30 years ago, when DDT was widely used.

Arctic animals such as whales, seals and birds have had a significant decline in their DDT levels during the past decades, while the more stationary Antarctic penguins have not. The study, “Melting Glaciers: A Probable Source of DDT to the Antarctic Marine Ecosystem,†published in Environmental Science and Technology (DOI: 10.1021/es702919n), identifies the melting snow and ice as the continued source of total DDT in this southern ecosystem.

The release of DDT also means that other persistent organic pollutants (POPs), including PCBs and PBDEs — industrial chemicals that have been linked to health problems in humans, are also being released.

“DDT is not the only chemical that these birds are ingesting and it is certainly not the worst,” Ms. Geisz says.

Ms. Geisz and her team sampled Adélie penguins and found similar DDT concentrations to those found when the penguins were sampled in a 1964 survey.  She found that the ratio of DDT metabolites, p,pâ€Â²-DDT to p,pâ€Â²-DDE declined over time. This shift indicates that the birds are exposed to the remnants of older DDT deposition. After examining glacial records, Ms.  Geisz found a likely explanation for the high concentrations of DDT. During the 1950s and 60s, a time when DDT use peaked, the Antarctic glaciers swelled, potentially locking in chemicals like DDT. However, average winter temperatures on the Antarctic Peninsula have warmed 6 °C in the past 30 years, and glaciers now melt faster than they grow. They estimate that DDT reenters the ecosystem at a rate of 1 to 4 kg per year.

DDT and other POPs follow atmospheric paths to the Antarctic and the Arctic and eventually are deposited there in snow and ice. Animals there sequester these contaminants in their fat. These toxic chemicals persist in the environment, bioaccumulate in food chains and are common contaminants in fish, dairy products and other foods. Many human and animal populations now carry enough POPs in their bodies to cause subtle but serious health effects, including reproductive and developmental problems, cancer, and disruption of the immune system. Indigenous communities in the Arctic region carry alarmingly high levels of these contaminants.

However Arctic and Antarctic communities are not the only ones at risk. A survey conducted by the National Oceanic and Atmospheric Administration (NOAA) found that fish caught in California’s Los Angeles county waters contain the world’s highest-known DDT concentrations (See Daily News of February 1, 2007). These findings contradict the belief held by some scientists that DDT on the ocean floor has been breaking down into less toxic compounds and would soon disappear from marine life. Earlier this year, the National Park Service (NPS) released a report detailing high levels of DDT and other POPs contamination within park boundaries.

DDT and its metabolites have been identified as endocrine disruptors. DDT acts as an estrogen mimic and wreaks havoc on biological systems, with adverse health effects showing up later in an organism’s development.

Vineyards and Community College Receive “Salmon-Safe†Certification

(Beyond Pesticides, May 7, 2008) Twenty-five vineyards representing 925 acres or 56 percent of vineyard acreage in the Walla Walla Basin in Washington state, as well as the 110-acre Walla Walla Community College (WWCC), are newly certified “Salmon-Safe†for their land practices that help accelerate salmon’s recovery. The designation means that landowners go above and beyond regulations to adopt significant and specific measures that restore in-stream habitat, conserve water, protect streamside habitat and wetlands on site, reduce erosion and sedimentation, and reduce or eliminate the use of chemical pesticides.Certification is awarded only after comprehensive on-site assessments by independent inspectors based on Salmon-Safe’s rigorous standards. Salmon-Safe is a leading regional eco-label that in 11 years has certified more than 60,000 acres of farm and urban lands in Oregon and Washington, including one-third of Oregon’s vineyard acreage, as well as the headquarters campuses of Nike, Washington State Department of Ecology, and Kettle Foods.“The magnitude of the participation underscores the Walla Walla valley’s leadership in adopting and committing to sustainable practices that benefit people and land, and help salmon spawn and thrive,†said Dan Kent, Salmon-Safe managing director. “The certifications and assessments also mark a major expansion of Salmon-Safe east of the Cascades, a region critical to salmon recovery efforts.”

“Great wine goes hand in hand with great respect for land, water and communities. We are committed to these values and Salmon-Safe is a vital management tool for us,†said Jean-Francois Pellet, president of VINEA: The Winegrowers Sustainable Trust. Also partnering on the assessments is the Oregon wine industry’s Low Input Viticulture & Enology (LIVE) program, which conducted the site inspections.

Walla Walla Community College received certification for its campus located along Titus Creek. The site provides potential migration and side channel rearing habitat for juvenile steelhead and Chinook salmon. “The college is making every effort to implement sustainable practices in everything we do, so we’re very pleased to apply the latest watershed concepts right here in our own backyard,” said Steven VanAusdle, Ph.D., WWCC President.

To qualify for Salmon-Safe certification, Walla Walla Community College has met rigorous conservation requirements including commitments to further restore stream and wetland habitats on campus, reducing stormwater runoff from developed parts of the campus, reductions in pesticide and fertilizer use, further water conservation, and Salmon-Safe design and construction management for planned future campus expansion and development.

The certified vineyards are: àMaurice Vineyard, Cockburn Vineyard, Dad’s Highway 11, Double River Estate Vineyard, Figgins Estate, Frenchtown Vineyard, Heather Hill, Les Collines Vineyard, Loess Vineyard, Margarets Vineyard, McClellan Estate Vineyard, Mill Creek Upland Vineyard, Mill Creek Vineyard, Octave Vineyard, Pepper Bridge Winery Estate, Seven Hills Vineyard, Seven Hills Vineyard West, Va Piano Vineyards, Wailser Vineyard, Waters-Upper Vineyard, Waters-Wondra Vineyard, White Space Vineyard, Winesap Vineyard, Woodward Canyon Estate Vineyard and XL Vineyard.

Because of Salmon-Safe’s rigorous whole farm requirement, the impact of certification extends beyond these vineyards as landowners growing other crops were required to certify all their operations in order to qualify for Salmon-Safe designation, leading to wider beneficial impacts on salmon habitat and water quality.

Pesticides that run off agricultural land and mix in rivers and streams combine to have a greater than expected toxic effect on the salmon nervous system, according to researcher Nathaniel Scholz, PhD, a zoologist with the National Oceanic and Atmospheric Administration (NOAA) in Seattle. In November 2007, a lawsuit was filed in federal by fishing and environmental groups seeking to force the federal government to uphold five-year-old rules aimed to keep toxic agricultural pesticides from endangering salmon and steelhead.

Pesticides and Other Occupational Risks Increase Miscarriage Rates of Veterinarians

(Beyond Pesticides, May 6, 2008) Pregnant veterinarians who have occupational exposures to pesticides, anesthetic gases or radiation may have twice the risk of miscarriage, according to a new study published in the May 2008 issue of the journal Occupational and Environmental Medicine.

The study, “Maternal occupational exposures and risk of spontaneous abortion in veterinary practice,” looked at the experiences of 1197 female veterinarians working in clinical practice, who graduated from Australian veterinary schools between 1960 and 2000, responding to a questionnaire-based survey. There was a twofold increase in the risk of miscarriage in women veterinarians who use pesticides at work.

The researchers found that there was also a twofold increase for those exposed to anaesthetic gases for more than an hour a week without using equipment to remove the gas from the air, and an 80 percent greater risk of miscarriage in those who performed more than five x-ray examinations per week compared with those who performed five or less. Veterinarians are often unable to leave the room whilst performing an x-ray because they have to hold the animal being x-rayed in order to restrain it.

Adeleh Shirangi, Ph.D., author of the research from the Department of Epidemiology and Public Health at Imperial College London, said, “Prior to our study, there had been very little research looking at female vets’ exposures to occupational hazards and how this affects their health. We found that many of the vets surveyed either didn’t have the safety equipment in their practices, or they had the equipment but weren’t using it correctly. We hope that our research will make vets aware of the need to fully protect themselves whilst they are working, especially if they planning to have a baby.”

Laurel Kaddatz, V.M.D., vice chair of the American Veterinary Association Council on Veterinary Science (CoVS) and owner of Pound Ridge Veterinary Center in New York, said the recent Australian study keeps precautions foremost in people’s minds. “For me, looking at this study as a practitioner, it reaffirmed the safety measures we take in our hospital,” he said. “We have active scavenging systems for anesthetic waste gases; personnel aren’t in the X-ray room during film exposure; and we don’t do any topical pesticide application here, either.”

On the recommendation of the CoVS, the AVMA last updated the information and language of the “AVMA position on veterinary facility occupational risks for pregnant workers” in late 2004. The policy starts by stating, “Although scientific data concerning the reproductive health effects of many occupational exposures is limited, the goal of creating a safe work environment for pregnant workers can be facilitated by awareness of inherent risks and then adopting procedures to minimize risk exposure.” The policy lists radiologic, biologic, and chemical exposure as areas of concern for pregnant workers. The policy states that pregnant workers ideally should avoid exposure to X-rays, anesthetic gases, and pesticides.

Aquatic Organisms Harmed by Golf Course Pesticides

(Beyond Pesticides, May 5, 2008) A new study indicates that some pesticides applied to golf courses in the Precambrian Shield of central Ontario may have an impact on aquatic organisms in adjacent watersheds. The study is published in the April issue of Environmental Toxicology and Chemistry.

Golf courses affect the environment by altering the habitat through the release of nutrients and pesticides. The Precambrian Shield region of central Ontario, Canada, a major recreational area, is especially susceptible to the impacts of golf courses as a result of the geology and hydrology of the region. The Shield area is characterized by many lakes, rivers, and streams. Golf courses in this area typically place turf on top of a sand base which allows chemicals used on the courses to migrate into surrounding bodies of water.

The study set out to determine (1) whether organic substances that are toxic to early life stages of fish are transported from golf courses in the Precambrian Shield and (2) whether toxic compounds occur in watersheds of golf courses at times that coincide with the application of pesticides to golf courses and other conditions conducive to surface runoff. To do so, two golf courses in the Muskoka region of central Ontario were monitored from May to November of 2002. Passive samplers, semipermeable membrane devices (SPMDs), were deployed within the golf course watersheds at monthly intervals. After the SPMDs were retrieved they were tested for toxicity using the fish species, Japanese medaka.

A range of herbicides, insecticides, and fungicides accumulated in the SPMDs, the researchers noted. Elevated toxicity occurred in the SPMDs that were deployed during periods of maximum fungicide application. Overall, no single compound or class of compounds in the SPMD extracts was wholly responsible for the observed toxicity to the early life stages of medaka.

The present study indicated that the compounds accumulated in the passive sampling devices were toxic to early life stages of the fish species. It cannot be stated definitively, however, that the contaminants discharged from the golf courses were a toxic hazard to other fish and aquatic organisms. Aquatic organisms’ sensitivity to toxins, stream flow, and other factors affect the degree of hazard.

Several beneficial management practices can be employed to decrease the potential that pesticides can leach from golf courses into the surrounding aquatic environment, restraint in the use of pesticides being the key to reducing the impacts. Golf courses often require intensive applications of chemicals for turf maintenance, both because high-quality turf conditions are expected by the users and because the turf must withstand low mowing and heavy traffic. The researchers suggested that educating golfers to lower their cosmetic standards may be the best management strategy.

This is not the first time that the use of pesticides on golf courses has raised concerns. For example, a 2004 study published in the Journal of Toxicology and Environmental Health gives a comprehensive review of the carcinogenicity and genotoxicity of pesticides commonly used on golf courses. The report found a link between use of certain pesticides on golf courses, such as 2,4-D, and cancer in humans and wildlife. In 2003, Florida officials found elevated arsenic levels in the soil and groundwater in South Florida golf courses from the herbicide monosodium methane arsenate (MSMA). Pesticide runoff from a golf course outside of Washington, DC killed fish, eels and crawfish of two streams that feed into the Potomac River in 2001. Just this month, Golf Digest published an article that discusses the environmental impact of golf and the general agreement that golfer expectations and management practices must move and are moving in an environmental direction.

For more information on golf course management, see Beyond Pesticides’ Golf program page. If you are a golfer or live near a golf course, check out the Environmental Principles for Golf Courses in the United States, a set of principles jointly developed by a group of leading golf and environmental organizations that seeks to produce environmental excellence in golf course planning and siting, design, construction, maintenance and facility operations, and encourage your local golf course to adopt these principles.

Groups Petition EPA to Stop Sale of Nanosilver Products

(Beyond Pesticides, May 2, 2008) The International Center for Technology Assessment (CTA) and a coalition of consumer, health, and environmental groups, including Beyond Pesticides, yesterday filed a legal petition with the Environmental Protection Agency (EPA), demanding the agency use its pesticide regulation authority to stop the sale of  250+ consumer products now using nanosized versions of silver. The legal action is the first challenge to EPA’s failure to regulate nanomaterials.

Increasingly, manufacturers are infusing a large and diverse number of consumer products with nanoparticle silver (“nanosilver”) for its enhanced “germ killing” abilities. Nanosilver is now the most common commercialized nanomaterial. CTA found over 260 nanosilver products currently on the market, ranging from household appliances and cleaners to clothing, cutlery, and children’s toys to personal care products and coated electronics. Yet as the legal petition addresses, the release of this unique substance may be highly destructive to natural environments and raises serious human health concerns. Last summer, a coalition of 40 organization called for much more comprehensive evaluation and regulation of nanomaterials, citing these concerns.

“These nanosilver products now being illegally sold are pesticides,” said George Kimbrell, CTA nanotech staff attorney. “Nanosilver is leaching into the environment, where it will have toxic effects on fish, other aquatic species and beneficial microorganisms. EPA must stop avoiding this problem and use its legal authority to fulfill its statutory duties.”

Nanotechnology is a powerful new platform technology for taking apart and reconstructing nature at the atomic and molecular level. Just as the size and chemical characteristics of manufactured nanoparticles can give them unique properties, those same new properties–tiny size, vastly increased surface area to volume ratio, high reactivity–can also create unique and unpredictable human health and environmental risks.

While silver is known to be toxic to fish and aquatic organisms, recent scientific studies have shown that nanosilver is much more toxic and can cause damage in new ways.Exposures are occurring during use and disposal. A 2008 study shows that washing nanosilver socks releases substantial amounts of the nanosilver into the laundry discharge water, which will ultimately reach natural waterways and potentially poison fish and other aquatic organisms. Another 2008 study finds that releases of nanosilver can destroy benign bacteria used in wastewater treatment.

The legal petition demands that the EPA regulate nanosilver as a unique pesticide that can cause new and serious impacts on the environment. The hundred-page petition calls on EPA to: regulate these nanotechnology products as new pesticides; require labeling of all products; assess health and safety data before permitting marketing; analyze the potential human health effects, particularly on children; and analyze the potential environmental impacts on ecosystems and endangered species.

“The law does not allow the agency to stand idle while a new legacy of toxic pollution emerges,” added Joseph Mendelson, CTA Legal Director. “In an era of toxic water bottles, now is the time for the EPA to prevent a serious new environmental issue from occurring.”

Many of the products in the petition’s appendix are meant for children (baby bottles, toys,stuffed animals, and clothing) or otherwise create high human exposures (cutlery, food containers, paints, bedding and personal care products) despite very little study of nanosilver’s potential human health impacts. Studies have questioned whether traditional assumptions about silver’s safety are sufficient in light of the unique properties of nanoscale materials.

Concerns over nanosilver were first raised by national wastewater utilities in early 2006. One then-new product, Samsung’s SilverCareTM Washer, releases silver ions into the waste stream with every load of laundry. In response, according to November 2006 media reports, EPA said that it would regulate nanosilver products as pesticides. However, one year later EPA published a guidance covering only the Samsung washer and allowing it to remain on the market.

Beyond Pesticides  joins the CTA petition with: the Center for Food Safety, Friends of the Earth, Greenpeace, ETC Group, Center for Environmental Health, Silicon Valley Toxics Coalition, Institute for Agriculture and Trade Policy, Clean Production Action, Food and Water Watch, the Loka Institute, the Center for Study of Responsive Law, and Consumers Union.

GAO to Congress: Take the Reins at EPA to Stop Undermining of Science

(Beyond Pesticides, May 1, 2008) In testimony responsive to a request last year by Senators Barbara Boxer (D-CA) and Hillary Clinton (D-NY), the Government Accountability Office (GAO) told the Senate Committee on Environment and Public Works on April 29 that EPA’s risk review process is plagued by delays, a lack of transparency, and interference from the White House and other agencies. In short, GAO concluded that the agency’s science is politicized, outdated, secret, and threatens the protection of people and the environment from harmful chemical exposures. In its testimony, GAO’s director of Natural Resources and Environment, John Stephenson, urged Congress to suspend EPA plans for reform, which GAO believes would institutionalize bad science, and require the agency to adopt its recommendations.

The testimony comes on the heels of an April 10, 2008 EPA decision, effective immediately, to revise its Integrated Risk Information System (IRIS). The program was severely criticized by GAO in a March 2008 report, Chemical Assessments: Low Productivity and New Interagency Review Process Limit the Usefulness and Credibility of EPA’s Integrated Risk Information System (GAO-08-440). While EPA said it would consider the report’s recommendations, GAO said in its testimony this week, Toxic Chemicals: EPA’s New Assessment Process Will Increase Challenges EPA Faces in Evaluating and Regulating Chemicals (GAO-08-743T), “EPA’s new process is largely the same as the draft GAO evaluated, and some key changes also are likely to further exacerbate the productivity and credibility concerns GAO identified.â€

Key issues that were recommended by GAO and ignored include streamlining its lengthy assessment process and adopting transparency practices “that provide assurance that IRIS assessments are appropriately based on the best available science and that they are not inappropriately biased by policy considerations.â€The report cites the dioxin assessment as an “example of an IRIS assessment that has been, and will likely continue to be, a political as well as a scientific issue.†In his testimony, Mr. Stephenson cites an example of clear Office of Management and Budget (OMB) interference in the IRIS process. “For example, without communicating its rationale for doing so, OMB directed EPA to terminate five IRIS assessments that for the first time addressed acute, rather than chronic exposure — even though EPA initiated this type of assessment to help it implement the Clean Air Act,†he said.

In her opening statement at the hearing, Chairwoman Boxer said,

The GAO report I am releasing today criticizes the Bush Administration changes to the risk assessment process and makes clear the danger faced by the public when political interference and the influence of polluters affects EPA’s ability to address the risks of toxic chemicals.Under EPA’s new approach politics can be-and already has been-injected into multiple stages in the process.

Even worse, the new procedure effectively requires the White House the Department of Defense (DOD) – which contracts out much of its weapons programs — to agree with EPA on any risk assessment before it goes forward and is made public. The entire process of White House and interagency debate is kept secret, which GAO and EPA scientists say undermines the credibility of EPA’s scientific assessments.

That is because EPA scientists are being pushed aside by White House operatives and polluters.

The result of the ongoing deterioration of the IRIS system is a database, according to GAO, that “is at serous risk of becoming obsolete because the agency has not been able to routinely complete timely, credible assessment or decrease a backlog of 70 ongoing assessments. IRIS was created in 1985 as a tool for agency consensus on the health effects of chronic exposure to chemicals. The current database contains assessment of more than 540 chemicals. The failure of IRIS characterizes the broader failure of the Toxic Substances Control Act (TSCA), which in 1976 authorized EPA to obtain information on chemicals and regulate those that cause an unreasonable risk to human health or the environment. According to GAO, EPA has used its authority to require testing for few of the over 60,000 chemicals that were in commerce when TCSA was enacted. GAO critiqued the program in two reports, one in 2005, Chemical Regulation: Actions Are Needed to Improve the Effectiveness of EPA’s Chemical Review Program (GAO-06-1032T), and one in 2006, Chemical Regulation: Options Exist to Improve EPA’s Ability to Assess Health Risks and Manage Its Chemical Review Program (GAO-05-458).

The GAO also compared TSCA and the European Union’s new chemical control policy Registration, Evaluation and Authorization of Chemicals (REACH) in two reports, Chemical Regulation: Comparison of U.S. and Recently Enacted European Union Approaches to Protect Against the Risks of Toxic Chemicals (GAO-07-825) and Chemical Regulation: Approaches in the United States, Canada, and the European Union (GAO-06-217R). GAO concludes that REACH puts the burden squarely on the chemical industry to provide regulators with health and environmental effects information, while TSCA does not.

Silver Nanoparticles Coming Out in Wash

(Beyond Pesticides, April 30, 2008) New research shows that socks impregnated with silver nanoparticles to keep them microbe and odor free, release these particles when washed. Once washed down the drain, the silver particles enter the environment where they may pose numerable unknown adverse effects. Researchers from Arizona State University report their findings in a study entitled; “Fate and transport of ionic and nanoparticle silver released from commercially available socks,†published in Environmental Science and Technology. Six commercial brands of nanosilver-treated socks were tested and their nanosilver content measured before and after wash. The socks were soaked in 1- or 24-hour-long wash cycles in distilled water without detergent to limit variables in the tests. One batch was soaked in tap water to simulate a more realistic washing.Using scanning and transmission electron microscopy, the remaining silver was analysed. Under the microscope, nanoparticles were found clumped together in the fabric, while some socks had tiny corkscrew-shaped nanosilver particles that stuck like burrs to the fabric, clinging more tightly than some simpler nanosilver forms. They found that socks had variable leaching rates, which suggests that the sock manufacturing process and how they are impregnated with silver may influence the release of silver. In spite of how they were attached to the fabric, some socks lost the bulk of their nanosilver after two to four washings.

“From what we saw, different socks released silver at different rates, suggesting that there may be a manufacturing process that will keep the silver in the socks better,” says Troy Benn, graduate student and co-author of the study. “Some of the sock materials released all of the silver in the first few washings, others gradually released it. Some didn’t release any silver.”

Nanosilver that leashes out of fabrics are released into wastewater treatment systems and into nearby aquatic systems. To determine the fate of these particles, the researchers also tested activated sludge from a local wastewater treatment plant. They found that the sludge did indeed contain nanosilver washed out from the socks. This may pose a concern for agriculture, since sludge is often used as agricultural fertilizer. Contaminated sludge would be unable to sustain the necessary microbes needed for healthy soil and crop cultivation. Silver particles may also leach from sludge into surface runoff, where they may enter rivers and streams.

Another important issue is that most nanosilver becomes ionic silver in water. Ionic silver does not just attack odor-causing bacteria, but can also hijack chemical processes essential for life in other microbes and aquatic animals.

“If you start releasing ionic silver, it is detrimental to a variety of aquatic organisms. Once the silver ions get into the gills of fish, it’s a pretty efficient killer,” said Mr Benn.

Although the exact amount is unknown, they estimate that more than half of the nanoparticles dissolve into ionic silver. Ionic silver could also react with sulfur to eventually form silver sulfides in the environment, which is less toxic than silver alone, but more persistent and may be more biologically available. This report is the first to detail the release of nanosilver from textiles in a domestic setting. The researchers concede that more work needs to be done to examine the environmental and health consequences of nanomaterials, as well as to increase awareness of nanotechnology’s role in everyday consumer goods.

Nanosilver has been touted for its antibacterial properties and is used in many products such as sporting goods, band-aids, clothing, baby and infant products, and food and food packaging. However, very little is known about where these particles end up when such products are put to use. In July 2007, a broad international coalition of 40 consumer, public health, environmental, and labor organizations released Principles for the Oversight of Nanotechnologies and Nanomaterials (see Daily News). This report calls for strong, comprehensive oversight of the new technology and its products, which is built on a precautionary foundation to prevent risks to the public, workers and the environment.

Law Leads to Home Depot Canada Stopping Toxic Pesticide Sales

(Beyond Pesticides, April 29, 2008) In the wake of provincial laws banning lawn chemicals, the Canadian division of Home Depot announced on April 22, 2008 that it will stop selling traditional pesticides in its stores across Canada by the end of 2008 and will increase its selection of environmentally friendly alternatives. Home Depot Canada is the first major home improvement retailer to stop selling pesticides nationwide.The decision coincides with legislation introduced on April 23, which bans the sale and cosmetic use of pesticides on lawns, gardens and parks in the Canadian province of Ontario. Quebec passed a similar ban in 2003. Additionally, there are currently over 55 municipalities in Canada where the residential use, but not sale, of pesticides is banned. Other garden supply and grocery stores have also stopped selling pesticides in Ontario and Quebec, but the Home Depot decision will affect stores nationwide.

Environmental and public health activists believe the provincial bans and Home Depot phase-outs demonstrate that the country has reached a tipping point. “I would say that now that we have Quebec and Ontario, there is huge pressure on the other provinces. The next obvious one would be British Columbia.†Gideon Forman, executive director of the Canadian Association of Physicians for the Environment told the Canadian newspaper Globe and Mail. “In terms of a cost-benefit analysis [of pesticide products], there is zero health benefit and the potential risk is enormous.â€

The chain plans to begin the phase-out immediately. By June, Home Depot anticipates that 62 of its Canadian stores will no longer sell pesticides, with all 166 stores offering environmentally preferred replacement products by the end of 2008. A total of 60 products will be affected.

“Like our customers, we, at the Home Depot, are concerned about the environment,” said Annette Verschuren, president of the Home Depot Canada and Asia. “We are going above and beyond government regulations by working with our suppliers to develop pesticide alternatives that are environmentally friendly and produce excellent results on lawns and gardens.”

The actions in Canada are also in stark contrast to the United States, where Home Depot’s U.S. parent continues to sell these products nationally.

TAKE ACTION: Tell Home Depot that U.S. residents deserve the same healthy communities as Canada. Demand that the company expand its Canadian decision to include all stores in the U.S. and around the globe. Contact: Home Depot Headquarters, Brad Shaw, Sr. Vice President – Corporate Communications and External Affairs, Chairman – Home Depot Environmental Council, 2455 Paces Ferry Road, Atlanta, GA 30339, 770-433-8211 (phone), 770-384-4211 (fax).

Judge Halts Spraying Planned for California

(Beyond Pesticides, April 28, 2008) On April 24, a Santa Cruz County, California Court ruled that the light brown apple moth (LBAM) is not an immediate threat and delayed aerial spraying of a pheromone pesticide, CheckMate, in order to complete an environmental impact report. Then California Governor Arnold Schwarzenegger decided to delay the aerial spraying, vowing to prove that the chemical is safe. According to the Santa Cruz Sentinel, “Judge Paul Burdick said the state did not prove that the invasive light brown apple moth poses an immediate threat to life or property. As a result, he said, an emergency exception to finish the review while the spraying continues was not justified.†Governor Schwarzenegger announced on the same day that the California Department of Food and Agriculture (CDFA) will postpone aerial spraying with the pheromone pesticide until acute toxicology testing of eye, inhalation, respiratory and other potential irritants is completed. “I am confident that the additional tests will reassure Californians that we are taking the safest, most progressive approach to ridding our state of this very real threat to our agriculture, environment and economy,” said Governor Schwarzenegger in a press statement. CDFA estimates that once the testing is complete the department will begin aerial treatment on August 17, 2008 in the Monterey-Santa Cruz coastal area.

In response to the court ruling regarding the LBAM eradication project, CDFA Secretary A.G. Kawamura stated, “My department will aggressively seek an expedited appeal of this ruling, which threatens the safety of our agriculture, environment, and economy. The light brown apple moth is a serious threat not just to Santa Cruz but to the entire state, and the method we are using is the safest, most progressive eradication program available.†Although CDFA continues to stress that LBAM is a serious threat, “When Burdick asked the state’s attorney for evidence of damage caused by the 10,000 plus moths found in Santa Cruz County since April 2007[,] [t]he state was not able to provide any,†according to the Santa Cruz Sentinel. CDFA has also stated that beginning May 5, 2008, pheromone-infused twist ties will be used to eradicate the light brown apple moth within the communities of Cupertino, Sunnyvale and San Jose. According to CDFA, moth pheromone, which is odorless and colorless, creates mating disruption by preventing male moths from locating females. Twist ties will be applied within a 200-meter radius covering 27.12 square miles, as part of CDFA’s eradication plan. Residents in this area will receive notices detailing the treatment and inviting them to an informational open house on Tuesday, April 29, 2008. Additionally, a second light brown apple moth has been detected in Sonoma County, in close enough proximity to a moth found in February that triggered quarantine regulations which are currently being prepared.

A cooperative eradication program run jointly by CDFA and the U.S. Department of Agriculture (USDA) is already underway to suppress and eradicate infestations in nine other counties along California’s Central Coast and Bay Area. Since its detection in February 2007, the LBAM has been found and quarantines have been enacted in the counties of Monterey, Santa Cruz, Santa Clara, San Mateo, Contra Costa, Marin, San Francisco, Alameda, Solano and Santa Barbara. A quarantine is pending in Sonoma County. Small, isolated infestations detected last year in Los Angeles and Napa counties have already been eradicated. Twist ties were utilized in both counties.There are many concerned about the pheromone application. Aerial spraying for the LBAM has resulted in 463 illness reports after spraying began last fall. Another concern is the populations of endangered and threatened moths and butterflies that could be impacted by the aerial applications. A number of counties in California’s Bay Area have voiced strong opposition to state plans to aerially spray.

The pesticide CheckMate LBAM-F works as a pheromone that disrupts the mating cycle of the moth. Least toxic alternatives for pest control include the use of pheromones. However, the uncertainty about so-called inert or undisclosed ingredients included in many pesticide formulations remains a serious concern. Beyond Pesticides advocates for full disclosure of all pesticide product ingredients, including so-called inert ingredients, questions the efficacy of aerial applications of any pesticide that, by their nature, cause unnecessary exposure, and is urging targeted ground efforts only as a last resort.

EPA Orders Scotts To Stop Selling Unregistered Pesticides

(Beyond Pesticides, April 25, 2008)  The Environmental Protection Agency (EPA) Region 5 this week issued a “stop sale, use or removal” order against Scotts Miracle Gro Co. and three affiliates, all of Marysville, Ohio, for illegal, unregistered and misbranded weed and fertilizer products with a cancer causing and endocrine disrupting pesticide ingredient. EPA will also issue a stop sale order to Scotts Lawn Care Service.Scotts has agreed to recall two products from all retail locations across the United States and to set up a process for consumers to safely return any unregistered products they may have purchased. EPA ordered the companies, collectively an international producer and distributor of lawn care products, to immediately stop selling and distributing the products which can be identified by the invalid “EPA registration number” listed on the package. Invalid registration number 62355-4 is marketed under names including “Garden Weed Preventer + Plant Food” and “Miracle Gro Shake ‘n’ Feed All Purpose Plant Food Plus Weed Preventer.” The active ingredient of this product is trifluralin, an herbicide that is a possible carcinogen and probable endocrine disruptor, among its health effects. Invalid registration number 538-304 is used primarily by Scotts Lawn Service, a lawn care company. It is marketed under names including “Scotts Lawn Service Fertilizer with .28% Halts,” “Scotts Lawn Service Fertilizer 0-0-7 Plus .28% Halts Pro,” “Scotts Lawn Service Fertilizer 14-2-5 Plus .28% Halts Pro” and “Scotts Lawn Service Fertilizer 22-0-8 Plus .28% Halts Pro.”

An EPA consumer hotline to answer questions about the action has been established at 888-838-1304 (9 a.m. – 4:30 p.m., Central Daylight Time). Questions may also be answered by the National Pesticide Information Center at 800-858-7378 (6:30 a.m. – 4:30 p.m., Pacific Daylight Time, including weekends). A fact sheet and regularly updated information are posted online by EPA.

At this time EPA considers the risks, if any, posed by these unregistered products to be unknown. EPA and its state partner Ohio Department of Agriculture are conducting a laboratory analysis of these products. EPA advises consumers not to use these products and to store them in a safe, cool and dry place such as a garage or utility shed, and not to dispose of them down the drain, in the garbage or at a community disposal site.

Under the Federal Insecticide, Fungicide and Rodenticide Act, all pesticides must be submitted to EPA for review, evaluation and registration to ensure that they do not pose an unreasonable risk to human health or the environment. The review process is not without its own controversies (such as approving dangerous uses or misleading labels), but a company bypassing the process eliminates the possibility for public comment on the potential risks of its product.

“A manufacturer such as Scotts cannot ignore the important legal requirement of registering its pesticides,” said Region 5 Administrator Mary A. Gade. “This is a serious violation of EPA’s system for protecting people and the environment from the potential harmful effects of pesticides. EPA will fully investigate this violation and take appropriate actions. We are committed to keeping the public informed about any health consequences and providing information to assure the safe recall of these products as soon as possible.”

Hundreds of EPA Scientists Report Political Interference

(Beyond Pesticides, April 24, 2008) An investigation of the Environmental Protection Agency (EPA) released yesterday finds that 889 of nearly 1,600 staff scientists reported that they experienced political interference in their work over the last five years. The report, Interference at EPA: Science and Policies at the U.S. Environmental Protection Agency, by the Union of Concerned Scientists (UCS), sparked the setting up of a May congressional oversight hearing on the issue.The study follows previous UCS investigations of the Food and Drug Administration, Fish and Wildlife Service, National Oceanic and Atmospheric Administration, and climate scientists at seven federal agencies, which also found significant administration manipulation of federal science.

“Our investigation found an agency in crisis,” said Francesca Grifo, director of UCS’s Scientific Integrity Program. “Nearly 900 EPA scientists reported political interference in their scientific work. That’s 900 too many. Distorting science to accommodate a narrow political agenda threatens our environment, our health, and our democracy itself.”

The UCS report comes amidst a flurry of controversial activity swirling around the EPA. Congress is currently investigating administration interference in a new chemical toxicity review process as well as California’s request to regulate tailpipe emissions. And in early May, the House Oversight and Government Reform Committee is expected to hold a hearing into political interference in the new EPA ground-level ozone pollution standard.  

UCS’s investigation includes dozens of interviews with current and former EPA staff members, analysis of government documents, and a questionnaire sent to 5,419 EPA scientists by Iowa State University’s Center for Survey Statistics and Methodology. The questionnaire generated responses from 1,586 scientists, but not all of the respondents answered every question. Among the UCS report’s top findings:

  • 889 scientists (60 percent) said they had personally experienced at least one instance of political interference in their work over the last five years.
  • 394 scientists (31 percent) personally experienced frequent or occasional “statements by EPA officials that misrepresent scientists’ findings.”  
  • 285 scientists (22 percent) said they frequently or occasionally personally experienced “selective or incomplete use of data to justify a specific regulatory outcome.”
  • 224 scientists (17 percent) said they had been “directed to inappropriately exclude or alter technical information from an EPA scientific document.”
  • Of the 969 agency veterans with more than 10 years of EPA experience, 409 scientists (43 percent) said interference has occurred more often in the past five years than in the previous five-year period. Only 43 scientists (4 percent) said interference occurred less often.  
  • Hundreds of scientists report being unable to openly express concerns about the EPA’s work without fear of retaliation; 492 (31 percent) feel they could not speak candidly within the agency and 382 (24 percent) feel they could not do so outside the agency.

UCS’s investigation reveals political interference is most pronounced in offices where scientists write regulations and at the National Center for Environmental Assessment, where scientists conduct risk assessments that could lead to strengthened regulations.

“The investigation shows researchers are generally continuing to do their work,” said Dr. Grifo. “But their scientific findings are tossed aside when it comes time to write regulations.”  

Nearly 100 scientists identified the White House’s Office of Management and Budget (OMB) as the primary culprit. In scientists’ responses to an essay question, “How could the integrity of scientific work produced by the EPA best be improved?,” OMB took center stage:

  • “Currently, OMB is allowed to force or make changes as they want, and rules are held hostage until this happens,” said a scientist at the agency’s Office of Air and Radiation. “OMB’s power needs to be checked as time after time they weaken rulemakings and policy decisions to favor industry.”  
  • “OMB and the White House have, in some cases, compromised the integrity of EPA rules and policies; their influence, largely hidden from the public and driven by industry lobbying, has decreased the stringency of proposed regulations for non-scientific, political reasons,” said a scientist from one of the agency’s regional offices. “Because the real reasons can’t be stated, the regulations contain a scientific rationale with little or no merit.”
  • “They [OMB] â€Â¦ have inappropriately stopped agency work that has been in progress for years due to their lack of scientific understanding,” said a scientist at the agency’s Office of Research and Development.

The UCS investigation also reveals that EPA scientists cannot freely communicate their findings to the media, public or colleagues. Seven-hundred-eighty-three respondents (51 percent) said EPA policies do not let scientists speak freely to the news media about their findings. Scientists also share anecdotes about being barred from presenting their research at conferences and their difficulties clearing research publication articles with EPA managers.

“Scientific integrity is the bedrock on which the federal science establishment must rest,” said Bill Hirzy, Ph.D., an EPA senior scientist and senior vice president of the National Treasury Employees Union, Chapter 280, the union that represents EPA scientists. “Too many EPA scientists have had to fight interference from political or private sector interests and fear retaliation for speaking out.”

Previous UCS investigations of other federal agencies show that the problem of political interference is not unique to the EPA. These investigations recently prompted a group of prominent scientists â€â€ organized by UCS â€â€ to call on the next president and Congress to strengthen protections for all federal scientists. The statement urges them to ensure that federal scientists have the freedom to publicly communicate their findings; publish their work; disclose misrepresentation, censorship or other abuses; and have their technical work evaluated by peers â€â€ all without fear of retribution.

Rep. Henry Waxman, chairman of the Government Oversight and Government Reform, in a letter inviting EPA Administrator Stephen Johnson to the committee’s May hearing, stated, “Political appointees at EPA and other agencies appear to be a major source of political interference.†He continued, “At May’s hearing, the Committee will examine one apparent example of this disturbing trend:   EPA’s recent revision of the national air quality standards for ozone.   You should also expect members of the Committee to ask about these survey results and other evidence of political interference with science at EPA.â€

Cosmetic Use of Lawn Chemicals Banned in Ontario

(Beyond Pesticides, April 23, 2008) Ontario is moving to reduce exposure to toxic chemicals by banning the sale and cosmetic use of pesticides. Legislation to be introduced today would make Ontario’s pesticide rules among the toughest in North America. It would also replace a variety of municipal by-laws in place across the province.Studies by public health experts are showing growing evidence of the potential health risk of pesticides, particularly for children. The ban would likely take effect next spring. It would not affect pesticides used for farming or forestry. Golf courses would still be able to use pesticides, but must meet certain conditions to minimize environmental impacts. Pesticides would still be allowed for control of mosquitoes and other insects determined to represent a health threat.

“Our generation is becoming more and more aware of the potential risks in our environment, not only to our health, but to our children’s health. That’s why we’re taking action on behalf of the next generation of Ontarians, and reducing their exposure to chemicals,†said Premier Dalton McGuinty.

“Many municipalities have already shown leadership in banning or restricting cosmetic-use pesticides. We’re extending that protection to all families wherever they live,†said Environment Minister John Gerretsen.

Over 44 per cent of Ontarians already live in a municipality where the cosmetic use of pesticides is banned. Groups such as the Ontario College of Family Physicians and the Canadian Cancer Society have been calling for a ban on the cosmetic use of pesticides as a prudent measure to protect our families’ health.

This new legislation, proposed by Premier Dalton McGuinty, comes after years of petitions from local grassroots movements and health groups to ban all cosmetic use of pesticides across the province because of growing concern about the potential harmful effects of these products on human health. (See Daily News of February 28, 2007) The law would prohibit 80 chemicals and 300 products that experts say pose a potential health risk. Similar bans have gone into effect in Toronto and Quebec.

A draft list of outlawed pesticides would soon be released and the final list will be determined by regulation after the province consults on the draft before next spring. The main impact of this action would be to eliminate the residential use of the popular lawn herbicide known as 2,4-D, which kills broad leaf weeds, such as dandelions. 2,4-D is the most widely used lawn chemical but several recent studies show that this pesticide can cause lymphatic cancer in exposed humans, while dogs are twice as likely to contract canine malignant lymphoma when exposed to lawns treated with the chemical. Other lawn chemicals like glyphosate (Round-up) and dicamba have also been linked to serious adverse chronic effects in humans. Health effects of the 36 most commonly used lawn pesticides show that: 14 are probable or possible carcinogens, 15 are linked with birth defects, 21 with reproductive effects, 24 with neurotoxicity, 22 with liver or kidney damage, and 34 are sensitizers and/or irritants.

Action: This spring, care for your lawn without putting your health and that of your family’s at risk. Least toxic alternatives for lawn care do exist. To find out more information, check out our Lawns and Landscapes program page.

Happy Earth Day, Celebrate with an Earth Dinner

(Beyond Pesticides, April 22, 2008) Earth Day, traditionally celebrated by the United Nations on the spring equinox, became a U.S. national holiday proclaimed by Senators Gaylord Nelson and John McConnell on April 22, 1970. It is a time to celebrate our planet, and all the life giving natural resources and beauty that the Earth provides and which we too often take for granted.

Most memorable holiday traditions involve family, friends, and of course, food. Building on this idea, the folks at the Organic Valley Family of Farms Cooperative joined with environmental and sustainable agriculture organizations to develop the Earth Dinner celebration. In developing the Earth Dinner idea, the organizers wondered, “Why doesn’t Earth Day have a tradition?†The Earth deserves a celebration too, and it made sense that an Earth Day tradition should revolve around local, sustainable and organic cuisine, and especially meaningful discussion about the impact farming has on the environment.

  • Buying foods grown and distributed locally supports the local farmers, allowing them and their families to stay on the land.
  • Buying foods that were grown using sustainable agricultural practices protects the soil and environment in countless ways.
  • Going organic ensures that you are feeding your loved ones foods that are free from pesticides, hormones and antibiotics, as well as the added knowledge that the animals were treated with respect and care throughout their lives.


Since its inception in 2004, Earth Dinners have been hosted around the worldâ€â€from Anchorage, Alaska to Western Australia. Top chefs around the country put their touch on the annual dinner in restaurants from Seattle, to Detroit, to Bozeman to New York City. Amateur chefs and home cooks did the same thing in their living rooms, at their kitchen tables, on patios and decks, in community centers and parks- gathering friends and family around tables laden with local and organic fare.

The Earth Dinner website provides lots of valuable information to help you host your own dinner and to make the evening more fun and meaningful. The site offers advice on planning a dinner at home, on campus and for kids. It offers “Earth-friendly” recipes and downloadable Earth Dinner cards, designed to spark stories and memories of the foods and people we love, and perhaps to inspire new thinking about the foods we choose everyday.

For more information on the Earth Dinner idea visit the website. For information on organic food, visit Beyond Pesticides’ Organic Food webpage.

Earth Day Action: Help keep resources available for farmers transition to organic. Currently, a provision in the House-passed Farm Bill,and other substitute language now floating around, stops the U.S. Department of Agriculture from curtailing hazardous pesticide use through its conservation programs, either by targeting specific contaminants that are poisoning water or hurting wildlife, or facilitating a transition to organic practices. Ask your elected officials to get this provision and similar language out of the Farm Bill!

New Report Shows Organic Foods Higher in Nutrients

(Beyond Pesticides, April 21, 2008) A comprehensive review of 97 published studies comparing the nutritional quality of organic and conventional foods shows that organic plant-based foods (fruits, vegetables, grains) contain higher levels of eight of 11 nutrients studied, including significantly greater concentrations of the health-promoting polyphenols and antioxidants. The team of scientists from the University of Florida and Washington State University concludes that organically grown plant-based foods are 25% more nutrient dense, on average, and hence deliver more essential nutrients per serving or calorie consumed. The findings are published in the Organic Centers’ report, New Evidence Confirms the Nutritional Superiority of Plant-based Organic Foods.

Nutrient levels were studied in 236 matched pairs of foods with scientifically valid results on the levels of ten nutrients, plus nitrates (high levels are undesirable because of food safety risks). Each matched pair contains a crop grown organically and another crop from a nearby conventional farm with similar soils, climate, plant genetics, irrigation systems, and nitrogen levels. In addition, the team ensured that the crops were picked at a comparable level of maturity, handled the same way after harvest, and tested in the same form using the same methods.

The team reviewed the study design and analytical methods used in 97 published, peer-reviewed studies appearing since 1980 (40 of which have been published since 2001).

The team identified eight or more valid matched pairs for ten nutrients, plus nitrates including:

  • Four measures of antioxidant activity;
  • Precursors of three vitamins A, C and E;
  • Two minerals (phosphorous and potassium);
  • Nitrates (higher levels are undesirable); and
  • Total protein.

There were 191 matched pairs in which the antioxidant, vitamin and mineral levels are compared. The organic food is more nutrient dense in 119 of these pairs, or 62%, compared to 36% of the conventional matched pairs with more nutrients. There are no differences in 2% of the pairs. The conventional samples contain modestly higher levels of protein in 85% of 27 matched pairs (an advantage), but also much higher levels of nitrates in 83% of 18 matched pairs (a nutritional and food safety disadvantage). Matched pairs comparing potassium, phosphorous, and total protein account for over 75% of the 87 matched pairs in which the conventional food is more nutrient dense. In general, compared to vitamins and antioxidants, these three nutrients are of less importance because they are present in the average American diet at adequate to excessive levels, according to the report authors. The organic food is more nutrient dense in 75% of the matched pairs comparing total antioxidant capacity, total polyphenols, and two key flavonoids, quercetin and kaempferol.

Several methods were used to place the magnitude of the differences in nutrient levels between organic and conventional foods into perspective. In two-thirds of the matched pairs favoring the conventional food, the differences in favor of conventional are under 10%, compared to 26% of the matched pairs in which the organic food is more nutrient dense by a margin under 10%. The premium in favor of the conventional food is 21% or greater in just 15% of the matched pairs in which the conventional food is more nutrient dense, whereas in the more nutrient dense organic food matched pairs, 41% favor organic by 21% or more, and 24% of the pairs are 31% or more nutrient dense. The largest differences are in the case of the flavonoid quercetin, where the organic foods are 2.4-times more nutrient dense on average, and nitrates, where levels are 1.8-fold lower in organic foods (a desirable nutritional feature).

Nutrient levels were studied in 236 matched pairs of foods with scientifically valid results on the levels of ten nutrients, plus nitrates (high levels are undesirable because of food safety risks). Each matched pair contains a crop grown organically and another crop from a nearby conventional farm with similar soils, climate, plant genetics, irrigation systems, and nitrogen levels.

The largest differences are in the case of the flavonoid quercetin, where the organic foods are 2.4-times more nutrient dense on average, and nitrates, where levels are 1.8-fold lower in organic foods (a desirable nutritional feature).

“We have carried out many careful comparisons of both nutrient levels and biological activity of antioxidant polyphenols in organic and conventional foods over the last five years,†said Neal Davies, Ph.D., professor in the School of Pharmacology at Washington State University, and a study co-author. “Not only are we seeing a general trend in favor of the nutrient density of organic food, but also evidence that nutrients are often present in organic foods in a more biologically active form.”

Besides nutritional values, there are a number of reasons to support organic agriculture, For example, a study published in the February 2008 issue of Environmental Health Perspectives finds that children who eat a conventional diet of food produced with chemical-intensive practices carry residues of organophosate pesticides that are reduced or eliminated when they switch to an organic diet.

TAKE ACTION: Buy organic foods for yourself and your family whenever possible. If organic foods are not easily accessible to you due to cost or distribution, consider buying organic for the foods you eat the most. To make sure your food is organic, look for the USDA Organic label. For more information on organic agriculture, see Beyond Pesticides Organic Food pages.

Call for Public Comments- Tell EPA to Cancel Deadly Wood Preservatives

(Beyond Pesticides, April 18, 2008) On Wednesday 16 April, 2008 the U.S. Environmental Protection Agency (EPA) released for public comment its revised risk assessments for three heavy-duty toxic chemical wood preservatives: chromated copper arsenate (CCA), pentachlorophenol (PCP), and creosote. Beyond Pesticides has maintained that the hazards associated with the use, storage and disposal of these three chemicals are unnecessary, given the availability of alternative materials. Let your voice be heard and demand that the EPA protect workers, children and communities from these toxins.Chromated arsenicals, such as (CCA), were widely used to treat decks and patios, picnic tables, playground equipment, walkways/boardwalks, landscaping timbers, and fencing and continue to be used on utility poles and wood treated for industrial purposes. The arsenic in CCA is a known human carcinogen and has been linked to nervous system damage and birth defects. Creosote, a complex mixture of many chemicals, is a restricted use wood preservative used for industrial and marine wood protection. PCP is already banned in several countries due to health or environmental risks under the Stockholm Convention on Persistent Organic Pollutants, which the U.S. signed in 2001, but has failed to ratify. PCP is widely used on utility poles and railroad ties.

Beyond Pesticides has called for a banning of these heavy duty wood preservatives and said that the voluntary phase-out of residential uses of these chemicals does not adequately protect public health or the environment. Even though wood for residential use may no longer be treated with these toxins, industrial uses (railroad ties, utility poles) continue to put workers and the public at risk. Occupational exposures increase the risk of cancers in workers. These chemicals also impact the environment and have been found in surface waters. In fact, the major source of contamination in surface waters and groundwater is wastewater from wood preserving facilities. Individuals living or working near wood preserving facilities are exceptionally susceptible to being exposed to surface water or groundwater, increasing their exposure and risk. These preservatives are also known to leach from previously treated wood. Children are also at risk if they put their unwashed hands in their mouths after touching soil or wood that is contaminated with these preservatives. As a result, public and environmental health continues to be compromised.

On December 10, 2002, a lawsuit, led by Beyond Pesticides, was filed in federal court by a national labor union, environmental groups and a victim family to stop the use of arsenic and dioxin-laden wood preservatives, which are used to treat lumber, utility poles and railroad ties. The litigation argued that the chemicals, known carcinogenic agents, hurt utility workers exposed to treated poles, children playing near treated structures, and the environment, and cites the availability of alternatives. A federal lawsuit [Civil Case No. 02-2419(RJL)] brought by Beyond Pesticides and others in December 2002 to force EPA to act on the highly toxic wood preservatives, PCP, creosote and CCA, was dismissed by Judge Richard Leon, U.S. District Court (Washington, DC) on March 21, 2005. Despite numerous requests by Beyond Pesticides and scientists, going back to 1997, which urged EPA to cancel the “heavy duty†wood preservatives, the judge found that, “Beyond Pesticides did not make formal requests to cancel and suspend the wood preservative pesticides registrations until late 2001 and early 2002.†Thus, the decision reads, “â€Â¦EPA did not became [sic} obligated to respond to Beyond Pesticides until the formal petitions were filedâ€Â¦.†Jay Feldman, executive director of Beyond Pesticides, called the judge’s ruling “unsound, given that EPA has been unresponsive to scientific findings in a timely manner, and inherently unprotective of public health.â€

Beyond Pesticide plans to develop a detailed response to the risk assessment. In the meantime, the organization urges the public to tell EPA that the only way to protect workers and communities from these dangerous wood preservatives is to cancel their registrations. For more information about these wood preservatives visit Beyond Pesticides’ Wood Preservative program page.

Experts Discuss the Greening of Golf Courses

(Beyond Pesticides, April 17, 2008) In what it calls the most important article it has ever published, Golf Digest in its May 2008 issue (pp 196-232) publishes an article, How Green is Golf?, which asks the hard questions about the environmental impact of golf in a series of in-depth interviews, including a builder, golf course superintendent, regulator and environmentalist. The article spans a range of opinions on water usage, pesticide contamination, and management practices, with general agreement that golfer expectations and management practices must move and are moving in an environmental direction, citing important ways in which attitudes and understanding must change. Despite the documented problems with pesticides, the head of EPA’s pesticide program, in what is described as a “rebuttal†to criticism of pesticides and the pesticide registration process that are highlighted, responds without addressing key specifics identified in the article and preferring to extol the virtues of the EPA’s pesticide program.

The article says in its introduction, “As water becomes scarcer, as organic management practices increase, as environmentalism and environmental legislation start to bite more than they have, as the economy struggles, and as we come to appreciate the aesthetics of golf courses in all their many natural, beautiful hues, the way the game looks will change. And the way it plays will change too, with firmer and faster turf demanding a return to shotmaking, creativity, the bump-and-run. It’s starring to happen already: The hot courses are not dutiful apostles of Augusta; they are unique, wild and woolly-looking layouts like Bandon Dunes, Sand Hills, Chambers Bay. Americans increasingly love to visit the rugged natural links of the British isles, where the game began.â€

In the piece, Jay Feldman, executive director of Beyond Pesticides, points out the hazards of pesticides to human health and the environment and the high degree of inadequate health and safety data, indicting EPA’s cumulative risk assessment process, which specifically permits the continued use of the potent nerve poison chlorpyrifos (trade name Dursban) on golf courses (after banning its residential uses in 2000) with the assumption that young children do not play golf. Mr. Feldman urges golfers to play a more active role in developing guidelines and approaches that support golf course superintendents’ strategies to avoid toxic chemical use. He criticized the Golf Course Superintendents Association of America (GCSAA) for walking lock step with the chemical industry which does not represent the interests of the golfers, superintendents or the environment. GCSAA, given an opportunity to respond in the article says, “These [chemical companies] provide funds that help enable us to deliver programs and services to our members and the golf industry. Many of these programs are focused on environmental management. It behooves us to work cooperatively with those manufacturers so that we can gather and distribute reliable and accurate information to our members.â€

EPA’s “rebuttal†by Debra Edwards, Ph.D., director of the Office of Pesticide Programs, does not dispute most of the specifics outlined in the Feldman interview. Instead, she uses her space on the Golf Digest website to offer a boilerplate characterization of the pesticide registration program. “[E]PA bases its decisions to register pesticides for use in the United States on scientific data showing that the pesticides meet applicable safety standards to protect human health and the environment when used as directed on product labeling,†Dr. Edwards says. She refers to “rigorous risk assessment†and “uncertainty factors†without addressing the deficiency of false assumptions, such as children not playing golf, and lack of attention to synergistic effects and mixtures. Without admitting that the agency is years behind a statutory schedule to fully test pesticides for endocrine disruption, she says “[W]e have now developed and will begin requiring new studies to help us understand whether endocrine disruption is the mechanism causing the effects,†but does not say when and how long it will take. In her rebuttal, Dr. Edwards prefers to focus on the number of completed reevaluations of existing pesticide food tolerances (9,721 over the past 12 years) rather than the quality or documented deficiencies in those reviews. Dr. Edwards cites the agency’s support of integrated pest management (with undefined toxic pesticide use) and reduced risk pesticides, without ever questioning the real need for toxic chemicals or advancing defined organic management systems not reliant on toxic pesticides.

On children and golf course exposure, Dr. Edwards appears to dodge the agency’s failure to fully address young children’s exposure to chlorpyrifos on golf courses, by ignoring the original 2000 decision that dismissed all children’s exposure and the more recent 2006 analysis that ignores children six and under. Dr. Edwards writes, “[W]e estimated the potential exposure and risks received not only by adults but also by both children aged 7-12 and teenagers in the chlorpyrifos risk assessment. The assessment of the use of chlorpyrifos on golf courses shows that this use met our rigorous safety standard.†However, first, as noted in EPA’s “Provisions of the June 2000 Memorandum of Agreement,†the agency exempted golf courses from the chlorpyrifos phase out with its decision: “Outdoor areas in which children will not be exposed [to chlorpyrifos], including only: golf course turf. . . “ Then, in its Memorandum entitled Finalization of Interim Reregistration Eligibility Decision (IREDs) and Interim Tolerance Reassessment and Risk Management Decision (TREDs) for the Organophosphate Pesticides over six years later on July 31, 2006 (authored by Dr. Edwards), EPA narrowed its definition of children, deciding it was not necessary to evaluate children six and under. (p.41) Junior golf can certainly begin at age 5, or before, exposing young children to a hazard that EPA assumes does not need to be evaluated. Children are especially vulnerable to chlorpyrifos and chemical exposure and suffer their greatest risk of adverse effect during this period of life.

Some say that the debate with EPA is becoming increasingly irrelevant as the market moves ahead to address key issues of environmental health. This has happened in the food and agriculture sector where organic food has grown to a $20 billion industry. The majority of non-golfers (66%), according to a 2007 Golf Digest survey, understands that pesticides used on golf courses can be a health hazard. The number of golfers who understand this (40%) has doubled since Golf Digest conducted a similar survey in 1994. A majority, or 64%, of golfers is willing to “play golf under less manicured conditions to minimize the use of pesticides on the course.†An even greater majority, 85%, is willing to “sacrifice some level of golf course landscape “perfection†to save water/prevent groundwater pollution.†The growing number of concerned golfers and the communities surrounding golf courses are having increasing influence over golf course practices. Jeff Carlson, golf course superintendent at the Vineyard Golf Club on Martha’s Vineyard, MA, interviewed in the article, manages an organic course with a focus on cultural practices and describes a number of approaches that he uses to manage insects, weeds and fungus, as well as the importance of support from the club. Mr. Carlson says that it is important that he is “. . .working with our members and explaining this idea of great playability versus visual perfection. We take the focus away from having every piece of fairway and rough perfectly green. The members have to be on board, or the superintendent wouldn’t last too long.†With a background in using chemical-intensive practices, Mr. Carlson says, “I am just so surprised that so much of our golf course is unaffected by not using pesticides. To see a course without any at all is something I’m really proud of.”

CA Defends Spray Plan for Moth, Critics Charge Scare Tactics

(Beyond Pesticides, April 16, 2008) The California Department of Food and Agriculture (CDFA) is warning that if pheromone spraying in the San Francisco Bay area is postponed this summer, more conventional insecticides could be used in the future to manage a larger-scale light brown apple moth (LBAM) infestation. The related legal brief was released Monday in response to a lawsuit that demands an environmental review before the pheromone, CheckMate, is sprayed this summer. A number of cities and counties have taken a stand against the spray, including Santa Cruz county’s lawsuit, the hearing for which is coming up on April 24.

CDFA is resisting the counties’ attempts to delay their LBAM action plan. “The risk of greater conventional pesticide is out there,” said CDFA spokesman Steve Lyle. According to the brief, the pesticide to be used would be bacillus thuringiensus (Bt), which is commonly used in other areas of the country to fight insects like the gypsy moth. One concern of local researchers is the area’s populations of endangered and threatened moths and butterflies, which would be further threatened by a non-selective insecticide.

Santa Cruz Councilman Tony Madrigal dismissed the brief as employing scare tactics. “They’re proposing a choice to the people between bad and worse,” he said.

In addition, the state has gone on the offensive against injury reports from the first round of pheromone spraying, which occurred last fall. The Office of Environmental Health Hazard Assessment, Department of Pesticide Regulation, and California Department of Public Health released a report last week that argues a lack of evidence showing reported illnesses were caused by the spraying. After analyzing a total of 463 reports of human symptoms after the spraying, most of which included respiratory symptoms, the report concluded, “It is not possible to determine whether or not there is a link between any of the reported symptoms and the aerial spraying.” Among several shortcomings found in the data, the report argued, “the reported symptoms are nonspecific and, and are quite common among the general population . . . Given the range of causes for these symptoms and the large number of individuals expected to experience such symptoms at any given time, the symptoms in the 463 reports cannot be clearly attributed to any specific cause.”

To improve future reporting, the three agencies are designing a streamlined program to collect illness reports, including providing training to physicians on how to identify pesticide-related symptoms. The report includes full recommendations to help prevent any “unexpected health events” in conjunction with future LBAM spraying.

State Senator Carole Migden released a statement following the report. She said, “OEHHA says that it was unable to confirm a link between spraying and adverse health effects because most health complaints did not contain enough information to determine the cause of symptoms. Clearly, people should refrain from assuming that this means that no link exists. What residents must understand is that the spraying plan for the Bay Area will be much longer in duration than last fall’s and that no long-term studies have been done on the health affects [sic] of the spray that will be used – a spray that encapsulates the pesticide in tiny plastic spheres that people will inhale. How can that possibly be good for us?”

Connecticut Town Bans Pesticides on Athletic Fields

(Beyond Pesticides, April 15, 2008) Thanks to the organizing efforts of the local Environmental Action Task Force, the town of Greenwich, CT has banned the use of pesticides on all of its athletic fields. The first application of the year, which was set for April 14, 2008, was cancelled after the Board of Selectmen passed a resolution mandating the ban.

“It’s very exciting,” Selectman Lin Lavery told Greenwich Time newspaper. “It shows the town’s commitment to being a leader on environmental issues.”

According to the newspaper, the Environmental Action Task Force proposed the resolution in response to a state law banning the use of pesticides on all elementary and middle school grounds, that goes into effect next year. But the task force took the mandate a step further, banning pesticides on all town athletic fields and instituting it a year early.

It seemed logical to move forward with a ban as quickly as possible once it was determined that these pesticides were toxic and potentially harmful to children, Lavery told Greenwich Time.

Pesticides, such as Barricade- containing the active ingredient prodiamine, which is used on town fields, is a possible human carcinogen and suspected endocrine disruptor. Michael Franco, M.D., a local pulmonologist who is chairman of the task force’s pesticides sub-committee is concerned about the pesticide’s carcinogenicity, developmental toxicity, links to behavioral problems and persistence in the soil.

A spokesperson for the Greenwich Parks Department called the move a “noble†thing to do, but believes an organic approach will be more labor intensive. However experience shows, organic management of playing fields can be cheaper, does not require “rest†time, as once believed, and are safer for the athletes.

For more information on organic athletic fields, see “Pesticides and Playing Fields,†published in the Summer 2006 issue of Pesticides and You, and Beyond Pesticides’ Lawns and Landscapes project page.

Maine Passes GE Crop Bill to Protect Farmers

(Beyond Pesticides, April 14, 2008) After almost a year and a half of debate on genetically engineered (GE) crops, the Maine Legislature passed a bill last week to protect farmers from genetic trespass. According to Protect Maine Farmers, the bill prevents lawsuits for patent infringement against farmers who unintentionally end up with GE material in their crops; ensures lawsuits that do occur will be held in the state of Maine; and, directs the Department of Agriculture, Food and Rural Resources to develop and implement specific practices, or Best Management Practices, for growing GE crops. One component of the bill that was supported by many Maine farmers but failed would have required all businesses selling GE seeds in Maine to report their annual sales data to the Maine Commissioner of Agriculture.

“Maine’s farmers now have some substantial assurance that if they save seed that has been contaminated by [GE] varieties, they are not at risk for a lawsuit,†states Logan Perkins, the lead organizer for Protect Maine Farmers. “Hopefully, the development of these Best Management Practices will give farmers the information they need to make good decisions about how to protect themselves, their livelihoods and their neighbors when using [GE] crops.†North Dakota, South Dakota and Indiana have already passed similar legislation.

The Bangor Daily News states that “In the 10 years that GE crops have been grown in Maine, there have been non GE-related lawsuits [in the state].†But, there have been more than 90 GE-based lawsuits filed against 147 farmers in 25 states, according to the Center for Food Safety.

The passage of the bill comes just weeks after the town of Montville passed an ordinance that makes it “unlawful for a person, partnership, firm, or organization of any kind to produce genetically modified organisms in the Town of Montville for a period of ten years.†For those residents that are currently growing GE crops, they have two years to phase them out. This is the first of such ordinances to be passed outside of California. In 2005, town officials in Kennebunk and Kennebunkport prevented voters from on a similar ban, stating that the ordinance conflicts with Maine’s right-to-farm law. Brooklin and Liberty passed non-binding ordinances establishing their towns as “GE Free Zones.â€

More and more GE crops are being grown around the world. The International Service for the Acquisition of Agri-biotech Applications reports that biotech crops grew by 30 million acres, or 12 percent, in 2007 for a total of 282.4 million acres worldwide. Also astounding is the fact that 2 million more farmers planted biotech crops last year to total 12 million farmers globally. Notably, 9 out of 10, or 11 million of these farmers, are resource-poor farmers. In fact, the number of developing countries (12) planting biotech crops surpassed the number of industrialized countries (11), and the growth rate in the developing world was three times that of industrialized nations (21 percent compared to 6 percent.)

An organic dairy farmer thinks that legislation needs to go a step farther, “It’s good to know that I will not be sued for saving my seeds, but I would like to see a way to make the companies take responsibility for the losses this technology can cause when it contaminates my crops.â€

There are many problems with GE crops as they are known to lead to insect resistance, create superweeds, contaminate other plants from the same species through pollen drift, harm human health, wildlife and other non-target organisms, contaminate soil, contain hidden allergens, negate religious and moral considerations, lead to antibiotic resistance, and unreasonable business contracts with farmers.

Investigation Finds FDA Failures Lead to E.Coli Outbreak

(Beyond Pesticides, April 11, 2008) The United States House of Representatives’ Committee on Oversight and Government Reform released a report last month on the Food and Drug Administration (FDA) failures that lead to the E.coli outbreak in spinach, which peaked in September 2006. When E.coli was discovered in package spinach, critics of organic agriculture and parts of the media were quick to target organic spinach as the source (starting something of a debunking “war”). NBC’s Today Show erroneously blamed organic agriculture (to which Beyond Pesticides responded here). However, the Congressional report lists a variety of failures on the part of FDA to ensure safe handling and packaging of spinach, citing a limited number of inspections and failure to enforce adequate sanitation and processing practices.

The major faults found by the committee range from frequency and thorughness of inspections, to lack of enforcement, including:

  • Packaged fresh spinach facilities were inspected only once every 2.4 years, less than half of FDA’s stated goals.
  • FDA observed objectionable conditions during 47% of the packaged fresh spinach inspections [60% of which pertained to facility sanitation].
  • Despite observing objectionable conditions in packaged fresh spinach facilities, FDA took no meaningful enforcement action.
  • FDA overlooked repeated violations.
  • FDA found repeated problems at multiple facilities operated by the firm implicated in the 2006 E.coli outbreak but took no enforcement actions.
  • In eight cases, packaged fresh spinach facilities denied FDA inspectors access to records or other relevant material.
  • The scope of FDA inspections appears too narrow to capture the sources of an E.coli outbreak.

In 2006, it was widely reported that the E.coli stemmed from organic spinach, which was fertilized with manure, as opposed to synthetic chemical fertilizers. The committee (and, by now, others) has pointed out “that the outbreak probably did not originate in the facilities that are inspected by FDA. Instead, the problem began outside the plants and most likely was due to contamination of the water outside of the plant by cattle feces, pig feces, or river water. FDA does not routinely inspect the fields except in outbreak investigations.”

In addition to this probability, Natural Selection Foods LLC was found to have multiple violations, “including indications that the facility failed to take effective measures to prevent extraneous materials from entering the food; failed to clean and maintain processing equipment; failed to ensure that condensation did not contaminate the product; and failed to review and verify plant records pertaining to sanitation.” In spite of these, “FDA never initiated any enforcement action against Natural Selection Foods,” which would go in, in 2006, to be identified as the source of the E.coli outbreak.

Natural Selection was quick to state that, “We continually search for new ways to improve food safety and note all observations provided by FDA inspectors during their audits.” However, FDA’s advisory committee, the Science Board, concluded, “We can state unequivocally that the system cannot be fixed within available resources.” Watchdogging government oversight will likely remain relevant in the foreseeable future.

Intersex Frogs More Common in Suburban Areas

(Beyond Pesticides, April 10, 2008) Common frogs that live in suburban areas are more likely than their rural counterparts to develop reproductive abnormalities, according to David Skelly, PhD, professor of ecology at the Yale School of Forestry and Environmental Studies. This phenomenon becomes a serious concern as the frog’s mating season begins, leaving researchers to wonder: will frogs be clear on their role in the annual ritual?

Research by Dr. Skelly, soon to be published, focuses on the common green frog, Rana clamitans, within the Connecticut River Valley. A total of 233 frogs were collected from various ponds and landscapes with the river valley and among them 13 percent have abnormalities occurring in their reproductive organs. In urban areas, 18 percent of the collected frogs are intersex, and in suburban areas 21 percent. Frogs collected from agricultural areas have the lowest rate of reproductive problems with just 7 percent classified as intersex. According to Dr. Skelly, the more suburban the land cover, the more likely the abnormalities.

“This is the first evidence that I think anyone has provided that agriculture is doing anything but pushing those rates higher,†remarked Dr. Skelly of the intersex phenomena.

In an attempt to explain the higher prevalence of intersex frogs in urban and suburban areas, the study notes that many suburban areas use septic systems that may be leaching chemicals or pharmaceuticals into streams or ponds. These areas also have higher rates of using herbicides and insecticides for lawn care and garden treatments.

Intersex frogs, also called hermaphroditic frogs, refer to frogs, mostly males observed to be producing eggs in their testes. There are many studies documenting this phenomenon, which is also blamed for the decline in many frog populations. Work by Tyrone Hayes, PhD, University of California, Berkeley, has linked the agricultural herbicide atrazine to reproductive disorders in frogs. A U.S. Geological Survey (USGS), also suggests a strong link between the abnormalities and agriculture. However, this study is the first to document the relationship with a non-agricultural setting.

Atrazine, which is classified as an endocrine disruptor, interrupts the workings of natural hormones. However, many household products, such as antibacterials and antimicrobials like triclosan and its cousin triclocarban, which are found in detergents, bar soaps, and other personal care products, have been shown to produce the same effects when released into streams and ponds. A recent study found that these antibacterials enhance endocrine disruption and have also been found to have the highest user rates among the wealthy. These antibacterials and other estrogenic chemicals are detected at high concentrations in the effluent discharged in the areas where the abnormalities are found. Lawn care chemicals like 2,4-D, permethrin, and glyphosate (Round-up) also cause damaging endocrine effects, even though the U.S. EPA does not currently evaluate or consider the endocrine disrupting properties of pesticides during registration or re-registration. These chemicals run off from treated lawn surfaces to contaminate nearby streams.

“Looking upstream and downstream from wastewater-treatment plants, we see there’s obviously been an impact by some of the chemicals discharged,†said Vicki S. Blazer, PhD, fish biologist at USGS.

Recent news reports have brought attention to antibacterials and pharmaceuticals in drinking water. While these chemicals pose serious health concerns to human populations, the harm posed to wildlife species being documented at alarming rates.

Urgent Action: Stop the Pro-Pesticide Lobby from Poisoning the Farm Bill

(Beyond Pesticides, April 9, 2008) You have an opportunity to ask your U.S. Representative to stand up for the protection of health and the environment by joining with his/her colleagues in the U.S. Congress on a letter to stop a pro-pesticide amendment in the Farm Bill, which is still under consideration in a House-Senate Agriculture conference committee. The provision, and other substitute language now floating around, stops the U.S. Department of Agriculture from curtailing hazardous pesticide use through its conservation programs, either by targeting specific contaminants that are poisoning water or hurting wildlife, or facilitating a transition to organic practices. (See March 27, 2008 Daily News) Attached below is the “Dear Colleague†letter that your Rep. received from Reps. Rush Holt (D-NJ) and Donald Payne (D-NJ) and the letter s/he is being asked to sign that will go to the Farm Bill conferees. To sign on, tell your Rep. (get contact info here) to email Rep. Holt’s aide Michele Mulder [email protected] or call her at (609) 750-9365.

“Dear Colleague†Letter to Your Member of Congress:

Don’t Turn Back the Clock on Safer, Less-Toxic, More-Environmentally Friendly Pesticides!

Dear Colleague:

I am writing to ask you to join me on a letter to the leadership of the House and Senate Agricultural Committees, urging them to support the Senate Agricultural Committees action in not including a provision passed in the House that would jeopardize the ability of conservation managers to choose the safest, least toxic, and most environmentally friendly pesticides in carrying out activities under integrated pest management and other Farm Bill programs. The provision, Section 11305 of the House-passed Farm Bill, was entitled No Discrimination Against Use of Registered Pesticide Products or Classes of Pesticide Products, and it read:

“In establishing priorities and evaluation criteria for the approval of plans, contracts, and agreements under title II, the Secretary of Agriculture shall not discriminate against the use of specific registered pesticide products or classes of pesticide products.â€

The provision, inserted at the behest of pesticide manufacturers, was met with outrage by more than 50 environmental, conservation, heath and nutrition, organic, wildlife, organic and other public interest groups. Numerous existing Farm Bill programs, encourage as they should — the use of non-toxic or less-toxic methods of pest control. The foregoing language could be interpreted to find such facilitation of safer pest control methods discriminatory as against the use of conventional pesticides, and could thus prohibit efforts to use such safer methods. This language drives Farm Bill policy on the issue of pesticide usage and environmental conservation in precisely the opposite direction from where it should be going. In a letter to the Natural Resources Defense Council dated February 8, 2008, the Environmental Protection Agency (EPA) agreed with the concerns expressed by conservation groups and stated that the EPA would be concerned if language in the House passed version of the Farm Bill could be interpreted in any way to inhibit [pesticide risk reduction].

Attached is a letter to the leadership of the House and Senate Agriculture Committees, urging them to follow the lead of the Senate Agriculture Committee and remove Section 11305 from the final Farm Bill. Please join me in co-signing this important letter. If you have any further questions or would like to co-sign the letter, please contact Michelle Mulder of my staff at (609) 750-9365 or [email protected].
Sincerely,

Dear Chairman Harkin, Chairman Peterson, Ranking Member Chambliss and Ranking Member Goodlatte:

We respectfully write to express our strong support for the Senate Committee on Agriculture, Nutrition & Forestry not including section 11305 of the House-passed Farm bill, entitled No Discrimination Against Use of Registered Pesticide Products or Classes of Pesticide Products, in the Senate bill. The provision read:

In establishing priorities and evaluation criteria for the approval of plans, contracts, and agreements under title II, the Secretary of Agriculture shall not discriminate against the use of specific registered pesticide products or classes of pesticide products.

We urge the Conference Committee to follow the lead of the Senate Agriculture Committee with respect to this issue, and leave that provision or similar provisions out of the final bill. Numerous existing farm bill programs, including the Environmental Quality Incentives Program (EQIP), the Conservation Security Program (CSP), the Conservation Reserve Program (CRP), the Wildlife Habitat Incentives Program (WHIP), and the Integrated Pest Management (IPM) programs operating at the state level, encourage the use of non-toxic or less-toxic methods of pest control The foregoing language was included in the House bill at the urging of pesticide manufacturers and, if allowed to remain in the final bill, would jeopardize the ability of conservation program managers to use farm bill funding to implement the most environmentally friendly pesticide options available. That is, EQIP and other programs that intentionally facilitate the deployment of non-toxic pesticides could be seen as discriminatory as against the use of conventional pesticides, and such facilitation would be prohibited under this language This language drives farm bill policy on the issue of pesticide usage and environmental conservation in precisely the opposite direction from where it should be going.

Attached are a letter from the Natural Resources Defense Council and a letter signed by more than 50 environmental, conservation, health and nutrition, wildlife, organic and other public interest groups, urging the Conferees to remove the House-passed Section 11305 from the final 2007 Farm bill.

We respectfully request the deletion of the House-passed Section 11305 from the final 2007 Farm bill.
