(Beyond Pesticides, November 14, 2011) Environment Canada’s enforcement division has indicted the multinational firm Cooke Aquaculture and three of its senior officials on eleven criminal charges stemming from illegal pesticide applications that spread to sicken and kill wild lobsters. The indictment alleges that in 2009 Cooke applied cypermethrin, a pesticide prohibited for use in aquatic settings in Canada, to control sea lice infestations in open water salmon net pens. The alleged applications occurred in the Passamaquoddy Bay which separates the Canadian province of New Brunswick from Maine and feeds into the Bay of Fundy. After dead and weakened lobsters were discovered in Canadian waters in the fall of 2009 and early 2010, Environment Canada linked the incidents to cypermethrin exposure and raided eight Cooke facilities. A conviction on the first count could result in a fine of $1 million with subsequent counts punishable by a $1 million fine or three years in prison, or both. Cypermethrin is a synthetic pyrethroid used for insect control in a number of agricultural and structural pest management settings. EPA has identified cypermethrin as a possible human carcinogen and classifies formulated pesticides containing it as slightly or moderately toxic. According to Susan Shaw, Ph.D., director […]

(Beyond Pesticides, November 8, 2011) The Environmental Protection Agency (EPA) published a petition to ban the endocrine (hormone) disrupting herbicide atrazine on September 14, 2011, opening a 60-day comment period for the public to weigh-in on the issue that ends Friday. Tell EPA that because atrazine poses unacceptable risks to humans and wildlife, the agency should remove this hazardous pesticide from the market immediately. Submit comments directly to EPA’s atrazine petition docket by November 14, 2011 or sign your organization or business onto Beyond Pesticides’ comments by Friday, November 11. According to its Federal Register notice, EPA received a petition from the non-profit organization Save the Frogs that includes over 10,000 signatures and select statements from the public, as well as two brief summaries of published literature, one by Jason Rohr, PhD (University of South Florida), and one by Tyrone Hayes, PhD (University of California, Berkeley), that is co-authored by 39 other scientists. In conjunction with the petition, EPA received nearly 50,000 emails from supporters of the Center for Biological Diversity and the Natural Resources Defense Council requesting that EPA “immediately take steps to phase out atrazine use in the United States,” stating that atrazine poses an unreasonable risk to […]

(Beyond Pesticides, October 27, 2011) Forty-seven students from Edgewood Middle School in St. Clair Township, Ohio, reportedly fell ill after the school’s hired pest control company sprayed the herbicide Momentum, which contains the toxic ingredients 2,4-D, triclopyr and clopyralid, on nearby playing fields to treat for clover and other weeds. The incident and others like it demonstrate the need for a comprehensive national policy to protect children from harmful and unnecessary exposure to toxic chemicals. Six students were taken to nearby hospitals and twenty-one students total were treated for symptoms, including headaches, breathing difficulties, nausea and dizziness. Children are especially sensitive and vulnerable to pesticides because of their rapid development and behavior patterns. Adverse health effects, such as nausea, dizziness, respiratory problems, headaches, rashes, and mental disorientation, may appear even if a pesticide is applied according to label directions, which may have been the case in this situation. Pesticide exposure can have long-term adverse effects, including damage to a child’s neurological, respiratory, immune, and endocrine system and increased asthma symptoms. Studies show that children living in households where pesticides are used suffer elevated rates of leukemia, brain cancer, and soft tissue sarcoma. For more information, see Beyond Pesticides’ fact sheet, […]

(Beyond Pesticides, October 17, 2011) Backlash from local residents in an Illinois city has pressured park officials to keep chemical pesticides off of athletic fields, successfully stopping a planned chemical treatment in November and postponing the city’s decision to spray until they hear more from concerned residents and turf experts. For four years, the Park Board of Highland Park, IL has managed its playing fields without the use of chemical pesticides and herbicides. Back in August, however, the Park Board decided to allow its groundskeepers to apply herbicides in order to control dandelions, clover, and other unwanted plants at three local parks. Over 70 residents sent emails to the Park Board and administration, and an online petition has collected 683 signatures opposed to the city park commissioners’ decision to spray the chemical pesticides. In response to public concern, Bruce Branham, PhD, a Professor of the Department of Crop Sciences at the University of Illinois wrote a statement to the park officials in favor of spraying, citing the U.S. Environmental Protection Agency (EPA) pesticide registration process as establishing the safety of the pesticides being proposed for use by the Park Board. Beyond Pesticides responded with a letter

(Beyond Pesticides, 9-30-11) Researchers from the University of Rhode Island (URI) have detected the antimicrobial triclosan and other toxic chemicals in the waters of Narragansett Bay off the coast of Rhode Island. The chemicals are a group of hazardous compounds that are common in industrial processes and personal care products but are not typically monitored by the U.S. Environmental Protection Agency (EPA). Rainer Lohmann, Ph.D., associate professor of chemical oceanography, and graduate student Victoria Sacks, with the help of 40 volunteers, tested for the presence of the chemicals in 27 locations throughout the bay. The compounds were found at every site. “Being exposed to these compounds is the hidden cost of our lifestyle,” said Dr. Lohmann. “It’s frustrating that as we ban the use of some chemical compounds, industry is adding new ones that we don’t know are any better.” Although the chemicals were detected at very low levels, research has shown that many chemical compounds can still be quite toxic, even at low doses. Additionally, since triclosan is an antimicrobial agent, low concentrations provide the perfect environment in which to breed and select for bacteria that resist the effects of the chemical. “By themselves, none of these results makes […]

(Beyond Pesticides, September 22, 2011) As part of his $3 trillion deficit-reduction plan, President Obama has proposed to increase pesticide and chemical registration fees and reinstate tolerance assessment fees in order to cover the costs of evaluating the chemicals’ health and environmental effects data. The U.S. Environmental Protection Agency (EPA) currently collects fees from companies seeking to register their pesticides or maintain existing registrations; however these fees do not cover the full cost of the review process. The White House fee collection proposal will save $740 million over 10 years. Under the reregistration program, pesticides that were registered prior to November 1, 1984 are evaluated to ensure that they continue to meet current regulatory standards. EPA began this effort under 1988 amendments to the Federal Insecticide, Fungicide and Rodenticide Act (FIFRA). The amendment also requires EPA to review all other registered pesticides on a 15-year cycle to ensure that registrations reflect current regulations. The reregistration of pesticides under FIFRA is a lengthy and ongoing process. Hundreds of pesticides currently registered and commonly used still lack a full assessment of their potential short and long-term effects on human health, particularly on children, and the environment. For example, EPA has failed to […]

(Beyond Pesticides, September 6, 2011) Scientists in France have discovered that honey bees are at a higher risk of dying from infection by Nosema ceranae (N. ceranae) when they are exposed to low doses of insecticides. The results, presented in the journal PLoS ONE, support the theory that combining more N. ceranae with high pesticide content in beehives could contribute to colony depopulation. The French study, “Exposure to Sublethal Doses of Fipronil and Thiacloprid Highly Increases Mortality of Honeybees Previously Infected by Nosema ceranae,” brought together researchers from the Laboratoire Microorganismes: Génome et Environnment and the Laboratoire de Toxicologie Environnment who utilized their respective skills in parasitology and toxicology to assess the effect of pathogen/toxin interactions on bee health. In the laboratory, the researchers chronically exposed newly emerged honey bees, some healthy and others infected with Nosema ceranae, to low doses of insecticides: fipronil and thiacloprid. They found that the infected bees died when they were chronically exposed to insecticides, even at sublethal doses, unlike the healthy bees. This combined effect on honeybee mortality was observed with daily exposure to extremely low doses (over 100 times less than the LD50 or dose needed to kill 50% of the sample population, […]

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

(Beyond Pesticides, August 1, 2011) After sighting three Japanese beetles in the vicinity of Greenback Lane and Fair Oaks Boulevard in Sacramento County, California, state officials are scheduled to spray pesticides linked to cancer, reproductive and neurological effects. On August 2, the California Department of Food and Agriculture (CDFA) is scheduled to begin ground applications of carbaryl on fruit-bearing trees, and cyfluthrin on non-fruit-bearing trees and landscape plants in attempts to stave of attacks from the voracious Japanese beetle. Japanese beetles, a threat to turf grass as well as ornamental plants such as roses and cut flowers, have been detected in the Fair Oaks area, state officials said, but the ”˜infestation’ appears to be localized. To keep the ”˜infestation’ from spreading countywide, Juli Jensen, Acting Agricultural Commissioner, is urging residents in the area not to move plants or plant parts. The initial treatments will be directed at adult beetles and begins August 2 with applications of carbaryl on fruit-bearing trees, and cyfluthrin on non-fruit-bearing trees and landscape plants. Two weeks later, a second treatment will be applied and augmented by a granular imidacloprid to target grubs. The applications, to occur on approximately 100 properties, will be carried out by the […]

(Beyond Pesticides, June 27, 2011) A study published in the May 2011 edition of the journal Reproductive Toxicology finds pregnant women and their fetuses contaminated with pesticides and metabolites of the herbicide gluphosinate and the Cry1Ab protein of the insecticide based on the bacterium bacillus thuringiensis (Bt), both affiliated with genetically engineered (GE) food. The study, “Maternal and fetal exposure to pesticides associated to genetically modified foods in Eastern Townships of Quebec, Canada,” also identified the same chemicals, as well as glyphosate metabolites in the bodies of non-pregnant women. The study, conducted by researchers at the University of Sherbrooke Hospital Centre in Quebec, Canada, is intended to pave the way for a new field in reproductive toxicology including nutrition and utero-placental toxicities. Herbicide resistance is the most common genetically modified trait in commercial agriculture. Crops are modified to be able to withstand extremely high doses of glyphosate (Roundup Ready) and gluphosinate (LibertyLink). Current herbicide resistant crops include soy, maize (corn), canola, sugar beet, cotton, with and alfalfa. As of 2005, 87% of U.S. soybean fields were planted with glyphosate resistant varieties. The recently released 2010 Agricultural Chemical Use Report by the U.S. Department of Agriculture’s (USDA) National Agricultural Statistics Service […]

(Beyond Pesticides, June 20, 2011) In a study published this week in the journal Pediatrics, researchers report findings that link mothers’ exposure to organochlorine pesticides during pregnancy with infants’ sizes at birth. The trend shows that the more mothers are exposed to the pesticides during pregnancy, the higher the chances are for reduced birth weight and length of their newborns. Comprising a total of 494 women and infants in Valencia, Spain from the years 2003-2006, the study evaluates umbilical cord blood for residues of four pesticides or pesticide degradates: DDT, DDE, hexachlorobenzene (HCB), and beta-hexachlorocyclohexane. The results show that a 10-fold increase in pesticide concentrations in the blood corresponds to a reduction in birth weight of 2-4 ounces. Additional results are correlated to specific pesticides. Higher concentrations of DDT results in a reduction in head circumference of 0.26cm, which the researchers call a “significant decrease.” Additionally, a decrease of 0.39cm in birth length is correlated with each 10-fold increase in concentration of HCB. The researchers note several concerns related to the findings, aside from the results themselves. Since people are exposed to a wide variety of chemicals in general throughout their everyday lives, higher pesticide exposure could betray higher exposure […]

(Beyond Pesticides, May 27, 2011) A coalition of environmental and public health groups filed a lawsuit yesterday against the federal Food and Drug Administration (FDA) to require the agency to enforce strict standards regarding the routine use of antibiotics in livestock feed. The suit, filed by the Natural Resources Defense Council, the Center for Science in the Public Interest, Food Animal Concerns Trust, Public Citizen, and the Union of Concerned Scientists, calls on FDA to implement regulations based on its own findings that the routine use of low doses of antibiotics in animal feed presents increased risk for the development of resistant bacteria. The non-therapeutic use of antibiotic drugs in animal feed presents a serious risk to public health due to the potential for bacteria to develop resistance to the drugs as a result of repeated low dose exposure. The rise of drug-resistant infections in humans has been linked to the overuse of antibiotics in animal feed since the early 1970s, but FDA has failed to meet its legal responsibility to address the mounting health threat posed by the practice, according to the groups’ suit. The coalition’s suit would also force the agency to respond to citizen petitions filed by […]

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

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

(Beyond Pesticides, April 28, 2011) In recognition of the 3rd annual Save the Frogs Day, a “Save the Frogs/Ban Atrazine Rally” will be held tomorrow, Friday, April 29th in Washington, DC. The rally will take place at the steps of the U.S. Environmental Protection Agency (1200 Pennsylvania Ave, NW), and is intended to raise awareness of the rapid disappearance of frog species worldwide, and bring attention to the harmful effects of the endocrine disrupting herbicide atrazine. Amphibian populations worldwide have been declining at unprecedented rates, and nearly one-third of the world’s amphibian species are threatened with extinction. Up to 200 species have completely disappeared in recent years. Amphibians are faced with an onslaught of environmental problems, including climate change, infectious diseases, habitat loss, invasive species, and over-harvesting for the pet and food trades. Numerous studies have definitively linked pesticide use with significant effects on amphibians. Pesticides can cause abnormalities, diseases, injury and death in these frogs and other amphibians. Because amphibians breathe through their permeable skin, they are especially vulnerable to chemical contamination. Frog eggs float exposed on the water surface, where pesticides tend to concentrate, and hatched larvae live solely in aquatic environments for five to seven months before […]

(Beyond Pesticides, April 22, 2011) Three independent investigations published in the journal Environmental Health Perspectives (EHP) have reached similar conclusions, associating prenatal exposure to organophosphate (OP) pesticides with IQ deficits in school-age children. The fact that three research groups reached such similar conclusions independently adds considerable support to the validity of the findings. The three studies were conducted at the School of Public Health at the University of California, Berkeley, the Mailman School of Public Health at Columbia University, and Mount Sinai School of Medicine. All three involved cohorts of women enrolled during pregnancy. The Berkeley and Mount Sinai investigators measured OP pesticide breakdown products in the pregnant women’s urine, while the Columbia investigators measured the OP pesticide chlorpyrifos in umbilical cord blood. Intelligence tests were administered to children of these mothers between ages 6 and 9 years at Mount Sinai and at age 7 years at Berkeley and Columbia. Although the study findings are not directly comparable, all three investigations found evidence linking prenatal OP pesticide exposures with adverse effects on cognitive function that continued into early childhood.”¨”¨“It is well known that findings from individual epidemiologic studies may be influenced by chance and other sources of error. This is […]

(Beyond Pesticides, April 14, 2011) Researchers at the University of South Florida have discovered that the most widely used fungicide in the U.S., chlorothalonil, is lethal to frogs even at low doses. Chemical pollution, according to the researchers, is considered the second greatest threat to aquatic and amphibious species in the U.S. Because many vital systems of amphibians are similar to those in humans, researchers believe that amphibians may be an underused model for studying the impacts of chemicals in the environment on human health and set out to quantify amphibian responses to chlorothalonil. The study, lead by Teagan McMahon, PhD, was published in Environmental Health Perspectives and opens the door for researchers to quantify the effects of the chemical on other species as well as other toxic pesticides on amphibian populations and human health. Researchers looked at Rana sphenocephala (Southern leopard frog) and Osteopilus septentrionalis (Cuban treefrog) in outdoor aquatic mesocosms (experimental water enclosures) with and without the expected environmental concentration as well as twice the amount of chlorothalonil. They also conducted two dose-response experiments on O. septentrionalis, Hyla squirella (squirrel treefrog), H. cinerea (green treefrogs), and R. sphenocephala, evaluating the effects of the fungicide on the stress hormone […]

(Beyond Pesticides, March 16, 2011) Congresswoman Louise Slaughter (D-NY) introduced legislation last week that seeks to help protect Americans from widespread antibiotic overuse in food animal production. Antibiotic use in agriculture, as well as in antimicrobial soaps containing materials such as triclosan, offer little to no benefit for public health, but instead contributes to increases in the growth of resistant bacteria. This makes antibiotic and antibacterial resistance a national health concern, due to the fact that it can make infections difficult or impossible to treat. Rep. Slaughter’s bill, H.R. 965 — the Preservation of Antibiotics for Medical Treatment Act, would preserve the effectiveness of antibiotics used to treat human disease by requiring the Food and Drug Administration (FDA) to revoke approval of antibiotics for non-therapeutic purposes unless the agency determines that the drugs do not produce unsafe levels of antibiotic resistance. The bill would allow farmers to continue to treat sick animals with antibiotics. “Antibiotic resistance is a major public health crisis, and yet antibiotics are used regularly and with little oversight in agriculture,” said Rep. Slaughter. The main culprits are confined animal feeding operation (CAFO) operators that routinely add human antibiotics to livestock feed for non-therapeutic purposes, such as […]

(Beyond Pesticides, March 10, 2011) The American Public Health Association (APHA) recently adopted 17 new policies at its 138th Annual Meeting in Denver, addressing a broad range of public health concerns, including a new policy calling for greater government action to protect the public from endocrine-disrupting chemicals (EDCs). The policy statement follows official positions released earlier in 2010 by both the American Medical Association (AMA) and the Endocrine Society in that more needs to be done to protect the public from endocrine-disrupting chemicals, or those that interfere with hormone action. Specifically, APHA urges: ”¢ Support for the Endocrine Society and the American Medical Association in proclaiming that more needs to be done to protect the public from potential health risks of exposure to EDCs. ”¢ That given the magnitude and urgency of the public health threat and the recognition that collectively EDCs likely will have common or overlapping effects on the endocrine system, steps should therefore be taken by federal agencies with regulatory oversight for various individual EDCs to coordinate and find synergies among themselves to coordinate and find synergy among federal agencies with regulatory oversight over various individual EDCs. ”¢ Health professionals and scientists with expertise in various aspects […]

(Beyond Pesticides, March 1, 2011) As insect resistance to pesticides steadily increases, and the underlying conditions of poverty, poor water management, and indecent living conditions contribute to the spread of malaria, the search for silver bullet solutions escalates. Researchers are exploring genetic engineering as the next frontier for a product-based approach to fighting malaria, which annually kills nearly one million people worldwide. While releasing genetically engineered organisms into the environment raises serious concerns that must be fully studied, some in the public health community believe this could help slow the spread of malaria as part of an integrated campaign. At the same time, the long-term underlying causes that support the spread of malaria must be addressed. The new research indicates that a genetically engineered fungus carrying genes for a human anti-malarial antibody or a scorpion anti-malarial toxin could be an effective tool for combating malaria, at a time when the effectiveness of current pesticides against malaria mosquitoes is declining. The researchers also say that this general approach could be used for controlling other devastating insect and tick bug-borne diseases, such as or dengue fever and Lyme disease. “Though applied here to combat malaria, our transgenic fungal approach is a very […]

(Beyond Pesticides, January 27, 2011) The U.S. Environmental Protection Agency (EPA) expanded protections for humans used as subjects in pesticide studies on January 19, 2011, making it harder for the chemical industry to experiment on people. EPA has proposed dramatic changes in how studies that intentionally expose people to pesticides can be conducted and in what studies it will accept. These proposed changes should force the chemical industry to avoid these types of studies altogether. EPA’s proposal is posted on the agency’s website and will soon be published in the Federal Register under Docket ID number EPA-HQ-OPP-2010-0785. Following this, the proposal will be open to a 60-day public comment period per a June 17, 2010 settlement agreement reached between EPA and a coalition of public health groups, farm worker advocates and environmental organizations. In 2006, the coalition, led by Natural Resources Defense Council (NRDC), filed a lawsuit against EPA, claiming that the agency’s 2006 rule violated a law Congress passed in 2005 requiring strict ethical and scientific protections for pesticide testing on humans. Attorneys with NRDC, Earthjustice, and Farmworker Justice served as legal counsel for the coalition. Specifically, the 2006 rule followed a temporary ban on human testing put in […]

(Beyond Pesticides, December 20, 2010) A new study examines the residue levels of the organophosphate insecticide chlorpyrifos in Colombian potatoes, finding that residual levels of the pesticide are still present even after being cooked. According to researchers, the pesticide has a tendency to build up in the raw potatoes, but once they were cooked, the levels dropped by 14%, leaving a fraction of the allowable levels of chlorpyrifos in the potato, under European Union (EU) daily intake limits. While it may be true that there are relatively low residual levels of the pesticide found in the potato once it has been cooked, many adocates are concerned about the remaining residues. The study, entitled “Pesticide Uptake in Potatoes: Model and Field Experiments,” was published in the journal Environmental Science and Technology. The fact that there remains some residual chlorpyrifos in the cooked potatoes is a concern because studies show that even at low doses, in utero exposure can cause changes in brain function and altered thyroid levels that last into adulthood. Young children are particularly susceptible to the effects of exposure. Because children’s diets often include significant quantities of potatoes, this is particularly alarming in light of a recent study that […]

(Beyond Pesticides, December 15, 2010) Every year, more than 10,000 kids are poisoned by rodenticides (pesticides made to kill rodents) and virtually all of the calls to U.S. poison control centers concern children under six. New rules and restrictions set by the U.S. Environmental Protection Agency (EPA) will go into effect next June in an attempt to prevent incidents involving children, but do not go far enough to protect children or wildlife. EPA has known for a generation that children have easy access to these super-toxic rat poisons. Every year, more than 10,000 kids are getting a hold of them, with Black and Hispanic children living below the poverty line being disproportionately affected. Records show that the EPA is aware that children have been getting into these poisons in significant numbers, according to data since 1983. Between 2004 and 2008, U.S. poison control centers continued to receive 10,000 to 14,000 calls about the rat killers annually. EPA has estimated that these incidents reported to poison control centers probably account for only about one-fourth of all exposures. On average, about 3,700 of these cases are treated by medical professionals each year, according to reports of the American Association of Poison Control […]
