(Beyond Pesticides, October 10, 2013) A recent investigation into the death of thousands of bees last month in Minnesota revealed that fipronil, a widely used insecticide, was to blame. In mid-September, three colonies of bees in Minneapolis were found twitching and dying on the ground. Local apiarist Mark Lucas paints a grim picture of the poisoning event, which he witnessed, recalling that bees inside the hive came “spilling out of the hive as if they were drunk.” University of Minnesota Bee Lab, the University’s Bee Squad, and the Minnesota Department of Agriculture (MDA) carried out the  investigation, taking samples from hives to confirm pesticide poisoning. Indeed, MDA tests found that all three of the affected hives tested positive for the presence of fipronil. Although neonicotinoid pesticides such as clothianidin, thiamethoxam, and imidacloprid have been widely implicated in the phenomenon of colony collapse disorder (CCD), other pesticides are known to adversely affect honey bee health. Fipronil has also been heavily implicated in elevated bee toxicity and decline. Indeed, the European Union (EU) recently put forth a proposal to restrict the use of the pesticide in recognition of the high acute risks it poses to bees. The chemical is widely used for […]

(Beyond Pesticides, September 15, 2013)A federal grand jury in Macon, Georgia allege that Steven A. Murray and his company, Bio-Tech Management wrongly used pesticides in multiple nursing homes across the state of Georgia. This misapplication is particularly egregious as the elderly are  especially vulnerable to pesticide exposure and the resulting adverse effects. Since 2008, Beyond Pesticides has worked with health care and elder care facilities to eliminate the use of toxic pesticides at their institutions. Hospital administrators typically recognize that the population served by their facilities have elevated risk factors with weakened immune and neurological systems, respiratory illness, cancer, and other pre-existing conditions or  illnesses that make them especially vulnerable to pesticide exposure. However, hospitals regularly contract for  pest control services from vendors and do not independently evaluate practices and product choices of the companies they hire. The indictment states that from October 2005 to June 2009, “[Bio-Tech] repeatedly misapplied the registered pesticide Termidor SC in nursing homes in the state of Georgia and falsified documents to conceal the unlawful use.” The indictment goes on to allege that Bio-Tech applied Termidor SC more than twice a year indoors. Termidor SC’s label clearly states that the pesticide can only be used […]

(Beyond Pesticides, July 18, 2013) A few months after the groundbreaking decision to suspend the use of three neonicotinoids shown to be highly toxic to bees, the European Commission is moving forward again with a proposal to restrict the use of the insecticide fipronil, which has also  been identified as posing an acute risk to honey bees. The proposal is backed by a Member State experts meeting in the Standing Committee on Food Chain and Animal Health. This proposal follows a European Food Safety Authority (EFSA)  scientific risk assessment, published on May 27, 2013, which found that seeds treated with pesticides containing fipronil pose an acute risk to Europe’s honey bee population. According to this assessment, it was found that fipronil poses a high acute risk to honeybees when used as a seed treatment for corn. Specifically, EFSA concluded that high acute risk from dust drift resulting from treated corn exists, and identified several data gaps and study limitations for other field crops. Data on nectar and pollen could not be evaluated. 23 Member States supported the fipronil restriction, 2 Member States voted against and 3 Member States abstained during the standing committee vote. This latest EU-wide restriction comes […]

(Beyond Pesticides, June 25, 2013) Traditional Chinese herbs, widely regarded for their medicinal properties, may not be as therapeutic as they seem. In fact, according to a new report released by Greenpeace East Asia, they may be toxic to your health. This news isn’t just disturbing for the Chinese people who live and work around where these toxic herbs are produced, but also for the entire global export market for Chinese alternative medicines, valued at $1.46 billion in 2010. The Greenpeace report found pesticides in 48 out of their 65 samples of traditional Chinese herbs, which included plants such as wolfberries, honeysuckle, the San Qi flower and chrysanthemum. Of these samples, the researchers discovered 51 different kinds of pesticide residues, with 32 of the samples tested containing traces of three or more different pesticides. In 26 samples, residues from pesticides that have been banned for use in agriculture in China were found, including phorate, carbofuran, fipronil, methamidophos, aldicarb and ethoprophos. This report isn’t the first where Chinese exports have been singled out for presence of pesticide contamination. In April 2012, Greenpeace released a report found that Unilever’s Lipton tea bags made in China contain pesticide residues that exceed the  European […]

(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: GĂ©nome 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, November 22, 2010) The British Beekeepers’ Association (BBKA) last week announced plans to end its controversial practice of endorsing pesticides for financial benefit from leading chemical manufacturers. The endorsement of four products as “bee-friendly” caused outrage among many beekeepers because one of the companies, Bayer Crop Science, makes pesticides like imidacloprid, an insecticide widely implicated in the deaths of honeybees worldwide. The 135-year-old charity endorsed pesticides used to combat the varroa mite that is linked to the collapse of colonies as “bee-friendly.” In return, for the past 12 years the association has received ÂŁ17,500 ($27,949) a year from Bayer Crop Sciences and Syngenta. This relationship angered many members and some left the association. However, the BBKA denies that it has bowed to pressure from members who have been increasingly critical of its relationship with Bayer and other chemical companies. In a statement sent out this week to the secretaries of local beekeeping associations across the UK, the BBKA’s president, Martin Smith, said: “Following discussion with the companies involved, the BBKA trustees have decided that endorsement and related product-specific payments will cease as soon as practically possible.” He added: “The four products subject to BBKA endorsement are of declining […]

(Beyond Pesticides, June 22, 2009) In April 2009, the U.S. Environmental Protection Agency (EPA) announced that it is intensifying its evaluation of spot-on pesticide products for flea and tick control for pets due to recent increases in the number of reported incidents. Adverse reactions reported range from mild effects such as skin irritation to more serious effects such as seizures and, in some cases, the death of pets. Incidents with flea and tick products can involve the use of spot-on treatments, sprays, collars and shampoos. However, the majority of the incidents reported to EPA are related to flea and tick treatments with EPA-registered spot-on products. Spot-on products are generally sold in tubes or vials and are applied to one or more localized areas on the body of the pet, such as in between the shoulders or in a stripe along the back. This advisory pertains only to EPA-registered spot-on flea and tick products; these products have an EPA registration number on the label. EPA now is evaluating all available data on the pesticides, including reports of adverse reactions, clarity of product use directions and label warnings, product ingredients, market share, and pre-market safety data submitted to the Agency. EPA says […]

(Beyond Pesticides, June 17, 2009) A new study finds that toxic pesticides, including those already banned, persist in homes. The study’s results indicate that most floors in occupied homes in the U.S. have measurable levels of insecticides that serve as sources of exposure to home dwellers. These persistent residues continue to expose people, especially vulnerable children, to the health risks associated with these chemicals. Published in Environmental Science and Technology, the study, entitled “American Healthy Homes Survey: A National Study of Residential Pesticides Measured from Floor Wipes,” was conducted as a collaboration between the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Housing and Urban Development. Five hundred randomly selected homes were sampled using alcohol wipes to collect dust from hard surface floors, mostly kitchen floor surfaces. The swipes were analyzed for 24 currently and previously use residential insecticides in the organochlorine, organophosphate, pyrethroid and phenylpyrazole classes, and the insecticide synergist piperonyl butoxide. Researchers found that currently used pyrethroid pesticides were, not surprisingly, at the highest levels with varied concentrations. Fipronil and permethrin, both currently used, were found in 40 percent and 89 percent of homes respectively. However, the researchers found that long discontinued pesticides like DDT and […]

(Beyond Pesticides, September 30, 2008) A group of insect-killing sprays known as neonicotinoids that are widely used in UK farming have now been banned in four other European countries because they are thought to be killing bees. Italy has just joined Germany, Slovenia and France in banning the sprays. This week the Italian government issued an immediate suspension of these sprays after they accepted that they are killing bees. Yesterday, the Britain’s Soil Association (SA) wrote to Hilary Benn, the Secretary of State for the Environment, urging him to ban the sprays in the UK with immediate effect. In the letter, SA Policy Director Peter Melchett wrote, “I fear it is typical of the current extraordinarily lax approach to pesticide regulation in the UK that we look like being one of the last of the major farming countries in the EU to wake up to the threat to our honeybees.” He also stated that the UK’s current pesticide regulation “is too dominated by scientists from one side of the debate about pesticide safety, fails to take adequate account of the public interest as against the interest of the chemical industry and some farmers, and fails adequately to apply the precautionary […]
