(Beyond Pesticides, January 17, 2020) In Brussels, the European Commission (EC) has just decided not to renew approval of the neonicotinoid pesticide thiacloprid, citing both environmental and health concerns related to use of and exposure to the pesticide. The decision was approved by a majority of European Union (EU) governments last fall, after the EC had made the proposal to them. The EC based that proposal on findings of the European Food Safety Authority (EFSA) published in January 2019, which highlighted concerns about toxicity to humans and high concentrations in groundwater. European Commissioner for Health and Food Safety Stella Kyriakides commented, “There are environmental concerns related to the use of this pesticide, particularly its impact on groundwater, but also related to human health, in reproductive toxicity.” The current EU use approval for thiacloprid products expires on April 30, 2020. The EC decision — functionally, a ban — means that farmers will need to turn to other means to deal with the primary thiacloprid targets in agriculture, aphids and whiteflies. Beyond Pesticides and many organic agricultural resources advocate for widespread adoption of organic, regenerative systems and practices. Such systems may include management features such as mechanical and biological controls, trap crops, natural […]

(Beyond Pesticides, January 15, 2019) A study published in the journal Environment International, Association of urinary metabolites of organophosphate and pyrethroid insecticides, and phenoxy herbicides with endometriosis, is the first of its kind. Researchers considered the endocrine-disrupting properties of pesticides (such as reduced sperm counts) and investigated whether there might be a relationship between pesticide exposure and endometriosis. Endometriosis is an estrogen-dependent gynecologic disease that affects about 176 million women globally. It can cause extreme pain and infertility as well as increased risk for cancer and cardiovascular diseases. This study finds a positive correlation between some pesticide metabolites and endometriosis, though authors encourage further study to corroborate the findings. Researchers examined exposure to 11 “universal pesticides” and their metabolites and its relationship to endometriosis in 492 reproductive-age women recruited from 14 surgical centers in Utah and California from 2007-2009. The women at these clinics were scheduled for laparoscopy or laparotomy—the “gold standard” for identifying endometriosis is through these surgeries. The study compares results from the clinical cohort to a group of women in the same age bracket from areas surrounding the participating clinics. 619 urine samples were analyzed from the operative and population cohorts. This study detected six of the […]

(Beyond Pesticides, January 14, 2020) Scientists have found a new method to reduce the sources of Lyme disease, but it is uncertain whether the finding will ultimately translate into fewer cases of human infections. Research published in the journal Experimental and Applied Acarology finds that incorporating Lyme vaccines into pelletized mouse food had the effect of reducing levels of Borrelia burgdorferi, the bacterium that causes Lyme disease, in both mice and ticks in a certain location. “So, the idea here is to vaccinate the mice,” study author Kirby Stafford, PhD told WBUR. “What we’ve done is incorporate a Lyme disease vaccine in an oral bait that would immunize them. That would prevent ticks feeding on those animals from becoming infected and then ultimately turn around and infect you.” To test their approach, researchers enrolled 32 homes in Redding, CT, an area where Lyme disease in endemic and several human cases are reported each year. Vaccine-incorporated mouse baiting stations were placed around 21 homes, while 11 acted as a control. Four times throughout the two year study period, mice and the ticks attached to them were trapped and tested for the disease. While there were no significant differences between the experimental […]

(Beyond Pesticides, January 13, 2020) Birds are facing an existential crisis. Three billion birds have disappeared since 1970. Two out of three birds are threatened by climate change. In spite of this crisis, our nation’s most important bird protection law, the Migratory Bird Treaty Act (MBTA) is being weakened by the Trump Administration’s Department of the Interior. Ask your U.S. Representative to support and cosponsor the Migratory Bird Protection Act. Thank those who are already cosponsors. Songbirds Threatened. The poisonous farm fields that migratory birds forage reduce their weight, delay their travel, and ultimately jeopardize their survival, according to “A neonicotinoid insecticide reduces fueling and delays migration in songbirds,“ published in the journal Science. Like their effects on insect pollinator populations, neonicotinoid insecticides generally do not cause acute poisoning and immediate death, but instead precipitate a cascade of sublethal impacts reducing their fitness in the wild. As the authors told Environmental Health News, the study is a call not simply to ban neonics or one class of chemical, but to change the entire farming system toward more sustainable bird and bee-friendly practices. Bird Habitat Threatened in Arkansas. A citizen science monitoring project of Audubon Arkansas found evidence of contamination from the weed killer dicamba far […]

(Beyond Pesticides, January 10, 2020) A new study by researchers out of the University of Iowa College of Public Health, published in JAMA (the Journal of the American Medical Association) Internal Medicine, demonstrates that greater exposure to pyrethroid insecticides is associated with higher risks of death from all causes and from cardiovascular disease. These compounds can be inhaled, ingested, or absorbed through the skin; they are highly neurotoxic, and have also been linked to certain cancers, endocrine disruption, and suppression of the immune system, as well as respiratory and reproductive impacts. The researchers gathered data, for 2,116 adults aged 20 or older, from the National Health and Nutrition Examination Survey. Each of those subjects had contributed a urine sample at some point between 1999 and 2002. Urine samples reflect levels of a pyrethroid metabolite (3-phenoxybenzoic acid) present, which in turn offer information about pyrethroid exposure. The researchers followed the participants until 2015; the research analysis was performed in the summer of 2019. Data were adjusted to accommodate multiple factors (age, sex, ethnicity, socioeconomic status, diet and lifestyle, smoking status, body mass index, and urinary creatinine levels). The co-authors report that subjects with the highest levels of metabolites had a 56% […]

(Beyond Pesticides, January 9, 2020) United States military veterans suffering from bladder cancer, hypothyroidism, hypertension and Parkinson’s-like symptoms after their exposure to Agent Orange will remain unprotected and uncompensated until at least late 2020, a letter sent by Veterans Affairs (VA) Secretary Robert Wilkie to U.S. Senator Jon Tester (D-MT) indicates. Congress included a provision in the must-pass December federal spending bill requiring VA to provide legislators “a detailed explanation” for the now multi-year delay in determining whether to list the diseases. This is seen by advocates for veterans as a serious lack of support and compensation just at a time when the current administration mobilizes the military. According to Military Times, 83,000 veterans suffer from bladder cancer, Parkinson’s-like symptoms or hypothyroidism, and an untold number have high blood pressure. The paper interviewed Army Sgt. Maj. John Mennitto, who explained, “Since we first spoke in 2016, I have been diagnosed with bladder cancer. . . I also have hypothyroidism. My greatest concern for me and my fellow veterans who have debilitating diseases caused by exposure to Agent Orange is that our family members will be left with nothing.” A robust 2014 review by the National Academy of Medicine recommended including […]

(Beyond Pesticides, January 7, 2020) It may seem peculiar at first sight, but painting zebra stripes on domestic cattle has the potential to significantly reduce the livestock industry’s use of toxic pesticides, according to research published last year by Japanese scientists at the Aichi Agricultural Research Center in Nagakute, Japan. Each year, farmers spend an estimated $1.6 billion on pesticides in the livestock industry, while biting flies cause over $2 billion of economic loss. This clever example of applied ecology could change those numbers with the added benefit of a safer environment.    While long considered a mystery, the science is now generally in agreement that zebras developed their stripes in order to confuse and ward off biting flies and the various ailments that can be passed on by the pests. While some cow breeds were developed with spotted patterns that may confer some fly deterrence, researchers used mono-colored Japanese Black cows to test their hypothesis. Six cows were separated into one of three groups: white and black stripes, black stripes, and an unpainted control. Stripes were painted with a water-based lacquer. The cows were observed starting 30 minutes after the paint was applied and allowed to air out. For […]

(Beyond Pesticides, January 6, 2020) In the midst of recalls of romaine lettuce contaminated with a pathogenic strain of E. coli, states and counties across the country are calling for a moratorium on large confined animal feeding operations (CAFOs). Now Senator Cory Booker is seeking to pass similar legislation at the national level. These industrial-scale operations are commonly referred to as “factory farms.” Tell your U.S. Senator to cosponsor the Farm System Reform Act introduced by Sen. Cory Booker. In the last week of November 2019, the Centers for Disease Control and Prevention (CDC) issued a food safety alert concerning a multistate outbreak of E. coli linked to romaine lettuce harvested from Salinas, California. As of November 25, 67 cases had been reported across 19 states, 39 of which required hospitalization, including six who developed kidney failure. The E. coli strain causing the outbreak — O157:H7, also known as STEC — is genetically identical to that responsible for lettuce-related outbreaks in 2017 and 2018. STEC is a dangerous, Shiga toxin-producing type of E. coli. Other outbreaks occurred earlier in 2019 as well. Dangerous strains of E. coli, including O157:H7, are typically associated with cattle in feedlot conditions. The first of the two […]

(Beyond Pesticides, December 17, 2019) South Asian immigrants to the U.S. may be at increased risk of diabetes due to prior exposure to high levels of DDT, research published by the University of California Davis earlier this month indicates. The study highlights a blind spot for health care in the U.S., researchers say. “Our findings evoke a new interpretation of Rachel Carson’s famous book Silent Spring, in that the high DDT exposures of South Asian immigrants in the U.S. currently fall on deaf ears in the U.S.,” said lead author Michele La Merrill, PhD an associate professor in the UC Davis Department of Environmental Toxicology. “Although DDT remains in use in other nations and migration globalizes these exposures, people in the U.S. often mistakenly regard DDT exposure as no longer relevant to our society due to its ban in this country nearly 50 years ago.” When compared to other race and ethnic groups, South Asian immigrants (individuals from India, Pakistan, Bangladesh, Nepal, Sri Lanka, and Bhutan), are at greater risk of developing diabetes, even when adjusting for potential confounders such as age and obesity. Authors of the study hypothesized that this was a result of past exposure to high levels […]

(Beyond Pesticides, November 12, 2019) Current USDA regulations clearly state that after a dairy farmer takes advantage of a one-time exemption to convert an existing “distinct” herd to organic production—all animals brought onto the farm must have been managed organically from the last third of gestation—in the case of cows, from three months prior to birth. However, USDA has interpreted the prohibition to mean that dairies could purchase animals, on an ongoing basis, who were born and raised on conventional dairies. These calves receive medicated milk replacer (formula laced with antibiotics) and, after weaning, are fed conventional GMO crops generally sprayed with Bayer/Monsanto’s Roundup.® Now, as livestock factories are taking over a good share of the organic market and pushing family-scale farmers off the land, USDA has finally, only after being forced by Congress, written additional regulatory language intending to close a loophole created by USDA’s negligence. Tell the USDA to follow the will of Congress and close its own loophole. The National Organic Program should enforce both the spirit and letter of the law. Organic farmers are mandated to provide healthy living conditions where livestock can exhibit their natural instinctive behaviors. When they do that—and for dairy cattle, that means […]

(Beyond Pesticides, November 7, 2018) A former employee of the Minneapolis Park and Recreation Board claims that other staff members misused and disposed of pesticides in protected areas next to Lake Harriet. The controversy comes at a pivotal moment for Minneapolis, as Minneapolis Public School District and the Park and Recreation Board are beginning a demonstration organic land management project on a number of properties. Advocates are pushing for organic land management as an alternative to chemical-intensive practices. Minneapolis gardener Angee Ohmah Siegal says she was at the Lyndale Park Peace Garden when she saw parks staff spraying herbicides on a windy day. According to Russ Henry, a local advocate who she told her story to, Siegal had to head to the hospital due to “uncontrollable vomiting.” What more, Siegal claims that the same employees would dump unused or leftover pesticides into a pond beside the Roberts Bird Sanctuary. Mr. Henry and Ms. Siegal issued their complaint with Park Board commissioners on October 2, carrying a large poster of a mutated frog with six legs that Ms. Siegal says she had photographed near the area. Commissioners are investigating further into the allegations but say they need more specific evidence. Volunteers […]

(Beyond Pesticides, November 6, 2019) Between 1981 and 1992, Japanese fishers annually reaped an average of 240 tons of smelt from Lake Shinji. After 1993, their nets turned up about 22 tons – a 90% drop in their yield. Eel catches dropped by 74%. New research, published in the journal Science, implicates the introduction of neonicotinoids to the abutting watershed in the decimation of these aquatic populations, stating, “In Lake Shinji, neonicotinoids indirectly reduced fishery yields by decreasing the abundance of invertebrates that serve as food for smelt and eels.” Researchers analyzed decades of data on zooplankton, midges, and water quality as well as annual fishery yields of eel and smelt spanning from 1981-2014. Zooplankton biomass, an important fodder for smelt, plummeted from 108 µg C L−1 to 18.2 µg C L−1 after imidacloprid was introduced for use on rice paddies in May of 1993. Midges (Cyathura muromiensis) that were found in abundance in 1982 totally disappeared from all sample sites by 2016. While the smelt and eel populations drastically declined, the authors note that icefish, which eat a more diversified diet, were not impacted. Though researchers considered the possibilities of other influencing factors such as invasive species, hypoxia, and […]

(Beyond Pesticides, November 5, 2019) Herbicide use is associated with an increased risk of developing cutaneous melanoma, a skin cancer, according to a meta-analysis published last month in the Journal of the European Academy of Dermatology and Venereology. For those working on farms and in other occupations with frequent exposure to herbicides, the risk is another in a long list of pesticide-induced diseases. Ultimately, researchers suggest, “A precautionary public health safety policy that includes preventive individual counselling and surveillance to workers exposed to pesticides may be advisable.” Authors of the study conducted a systematic review of the peer-reviewed literature on pesticide exposure and skin cancer, finding nine acceptable studies for analysis. These studies represent nearly 185,000 individuals, and included enough data to make a risk estimate and determine 95% confidence intervals. Although pesticides and insecticides in general were not associated with increased risk of skin cancer, general use of herbicides was (relative risk 1.85; 95% confidence interval, 1.01-3.36). Spouses whose partners work as pesticide applicators are also found to be at higher risk of developing cutaneous melanoma. As skin cancer has increased significantly over the past 50 years, many appropriately point to the link between sun exposure and development of […]

(Beyond Pesticides, November 4, 2019) In recognition of the harm that climate change is causing to communities, the U.S. House of Representatives formed the Select Committee on the Climate Crisis to “investigate, study, make findings, and develop recommendations on policies, strategies, and innovations to achieve substantial and permanent reductions in pollution and other activities that contribute to the climate crisis, which will honor our responsibility to be good stewards of the planet for future generations.” Tell the U.S. House Select Committee on the Climate Crisis to promote organic agriculture and land care. Regenerative organic agriculture reduces emissions of carbon dioxide and nitrous oxide. In nonorganic, chemical-intensive agriculture, greenhouse gas emissions result from the use of nitrogen fertilizer, synthetic herbicides and insecticides, fossil fuel consumption associated with farm equipment, and the transportation of materials and products to and from the farm. The manufacture of synthetic fertilizers and pesticides is a major source of energy use in chemical-intensive agriculture–the manufacture and use of synthetic nitrogen fertilizers alone are responsible for as much as 10 percent of direct global agricultural emissions. This is important because pound-for-pound, nitrous oxide is 300 times as potent as carbon dioxide in warming the planet. Besides reducing energy use, organic […]

(Beyond Pesticides, November 1, 2019) The recently published report Pesticide Residue Monitoring Program Fiscal Year 2017 Pesticide Report, from the U.S. Food & Drug Administration (FDA), provides data on the levels of pesticide residues that show up on the foods U.S. consumers eat. The report adds fuel to public concern about contamination of the food supply, and to discussion in the scientific and advocacy communities about what is and is not safe for human health. It is also a sobering reminder of just how much chemical-intensive agriculture depends on pesticides, whether insecticides, herbicides, or fungicides. This FDA report has been prepared annually since 1987 and is based on the agency’s Pesticide Residue Monitoring Program, which evaluates both domestically produced and imported human food samples, including fruit, vegetable, and animal products. As the report notes, “Three federal government agencies share responsibility for the regulation and oversight of pesticide chemical residues in or on food. The U.S. Environmental Protection Agency (EPA) registers (i.e., approves) the use of pesticides and establishes tolerances for pesticide chemical residues in or on food resulting from the use of the pesticides. Tolerances are the EPA-established maximum residue levels (MRLs) of a specific pesticide chemical that is permitted in […]

(Beyond Pesticides, October 30th, 2019) This month, the Thai government moved to ban some toxic chemicals out of concern for the health of its residents and environment. In response, U.S. Department of Agriculture (USDA) Undersecretary Ted McKinney sent a document to Thailand’s Prime Minister Prayuth Chan-ocha pushing back on their plan. As the Thai government makes changes to protect the health and represent the will of the people, the U.S. acts on behalf of its allegiance to agrichemical companies on an international stage. After powerful and sustained activism from local advocacy groups such as BioThai, the Thai government decided to upgrade glyphosate, chlorpyrifos, and paraquat from Type 3 toxic substances to Type 4, meaning these chemicals will no longer be allowed to be produced, imported, or possessed in the country. Witoon Lianchamroon, director of BioThai, says glyphosate and paraquat “contaminate our water, the soil, and some species like crab or fish or frog. These two main herbicides cover around half of the total pesticide use in the country and they cause a lot of problems.” The ban was approved by the National Hazardous Substances Committee, made up of 29 experts in the field, on October 22. Beginning December 1, the ban […]

(Beyond Pesticides, October 29, 2019) The U.S. Environmental Protection Agency is proposing changes to the way farmworkers and bystanders are protected from toxic pesticide applications, per an announcement published on the agency’s website last week. Billed as “improvements” that will “reduce regulatory burdens for farmers,” the actions would instead significantly shrink Application Exclusion Zones (AEZs), buffer areas where individuals are not supposed to enter during a pesticide application. Health and justice advocates say the move will put farmworkers at risk. “Although the proposal is framed as a narrow revision, it would in fact eliminate, reduce or weaken various AEZ provisions,” said Farmworker Justice attorney Iris Figueroa to Politico. “These changes threaten to increase exposure to toxic pesticide drift for farmworkers and their families.” EPA’s proposal, announced in a press release featuring the heads of industry associations like the American Farm Bureau, would do the following: Make AEZs applicable only to a farm owners’ property. Under the current rules, pesticide handlers were required to keep individuals out of an area where pesticides were applied both on and off site. Exempt on-farm family members from all aspects of the AEZ. EPA says this will allow farmers and their family “to decide whether […]

(Beyond Pesticides, October 27, 2019) The spraying of toxic herbicides for weed control on campuses exposes students, workers and the general public to chemicals linked to health problems such as cancer and reproductive issues. Any day now, the University of California system will decide whether or not to continue using glyphosate and other toxic herbicides — including Roundup — on their campuses. The University of California temporarily banned the use of cancer-causing glyphosate, the main ingredient in Roundup, but the ban doesn’t stop the UC system from using other dangerous herbicides. Student activists are asking UC to commit to transitioning to all organic land care maintenance on all University of California campuses by 2025. This could be an opportunity for the University of California, which prides itself on its commitment to sustainability, to join other universities such as Harvard, the University of Colorado at Boulder, Yale, University of Pennsylvania, and others as a national leader in the field. Tell University of California President Napolitano to issue a full, permanent ban on toxic herbicides and shift the UC land care system to organic! Message to University of California President First of all, I would like to thank you for temporarily suspending the use of glyphosate-based herbicides on […]

(Beyond Pesticides, October 24, 2019) Fish and fruit are undoubtedly healthy foods, but modern-day contamination is leading scientists to caution pregnant mothers and young children to stick within current dietary guidelines, or switch to organic, in order to avoid adverse health effects. This new public health message is based on research published in the journal Environmental Health Perspectives by scientists from University of Southern California (USC) and several European Countries, finding that overconsumption of fish and fruits leads to higher levels of contamination with toxic persistent chemicals. “During gestation and early development, the fetus and the child, respectively, are vulnerable to the effects of environmental chemicals, said Lida Chatzi, MD, associate professor of preventive medicine at the Keck School of Medicine of USC. “A balanced diet during these periods is also critical for optimal nutritional status, but what to eat, and how much, are critical questions.” Scientists studied a cohort of 1,288 children (between 6 and 11 years) and 818 pregnant mothers from six European countries, who were provided questionnaires to assess their weekly diet. Blood levels of a range of environmental toxicants, including organochlorine compounds like PCB, PFHSs, PFOS, PFOA, pesticides like DDT and DDE, and heavy metals including […]

(Beyond Pesticides, October 23, 2019) Bees provide benefits to farmers that outweigh synthetic inputs, according to a large-scale field study published in Proceedings of the Royal Society B earlier this month. Addressing the ongoing question of how much natural ecosystem services are worth, scientists analyzed the costs and benefits of biodiversity versus agrichemicals. Researchers found the value pollinators add to oilseed rape (OSR) production by increasing yields is higher than synthetic chemical inputs, which are costly to farmers and decrease beneficial insect abundance. The title of the study touts the impressive findings, “Bee pollination outperforms pesticides for oilseed crop production and profitability.” Researchers collected data over six years from 294 OSR fields in France with various levels of soil quality, fertilizer and pesticide applications, and pollinator abundance. They measured pollinator biodiversity with nets and traps at the field sites. Farmers offered data on yield, costs, and profits. Using linear models fitted to the large data set, the study analyzed combined effects of inputs on OSR yield and gross margin. Bee abundance was the only variable that had a positive effect on gross margins. Pollination is an ecosystem service that benefits one out of three agricultural crops. Studies from Ireland show […]

(Beyond Pesticides, October 20, 2019) USDA’s National Organic Standards Board (NOSB) should remove nonorganic celery powder from the National List of Allowed and Prohibited Substances for use in organic food production. It has been long-established that nitrates and nitrites, used to prevent bacterial growth in processed meats, react with protein to create nitrosamines, which are widely considered to be possible carcinogens. The World Health Organization considers processed meat “a known carcinogen.” Tell NOSB to remove carcinogenic nonorganic celery powder from organic processed meat. For too long the meat industry, including organic processors, have engaged in a form of subterfuge by being able, and in fact required, to label meat preserved with celery powder as “no nitrates or no nitrites added” or “uncured.” The use of conventional celery powder, with amped up applications of synthetic nitrogen fertilizer, creates the same functional and biological impacts as synthetic nitrates/nitrates as a meat preservative. The federal laws governing organics are clear. To legally use a synthetic compound, or a natural or agricultural material that is not certified organic, in the production of certified organic product, it must appear on the list of approved substances. And to do so, proposed materials must not damage the environment or […]

(Beyond Pesticides, October 17, 2019) The U.S. Environmental Protection Agency (EPA) is downplaying the connection between exposure to the herbicide paraquat and the development of Parkinson’s disease, per registration review documents released by the agency this week. Although unsurprising given the current administration’s track record of defending some of the most heinous chemicals still on the market, the review nonetheless marks a low point for scientific integrity within EPA’s Office of Pesticide Programs, according to advocates. Health and environmental advocates have already discounted EPA’s industry-biased review, and are instead pushing hard for Congressional action – namely HR 3817, the Protect Against Paraquat Act, introduced by Congresswoman Nydia Velazquez (D-NY). Under federal law, pesticides are required to undergo reevaluation every 15 years. Paraquat is a potent restricted use herbicide, not available to be applied by residential users, but permitted for use on multiple agriculture crops. Over the last decade, independent peer-reviewed scientific studies have repeatedly found strong associations between paraquat to the development of Parkinson’s disease. Many of these studies have been covered in Beyond Pesticides’ Daily News or are recorded in the Pesticide-Induced Diseases Database. In response to this growing body of literature, EPA conducted an epidemiological evaluation of published […]

(Beyond Pesticides, October 15, 2019) EPA is requesting comment on its proposal to require data that will help it determine synergistic effects of some pesticides. EPA has received on a pressure on a number of fronts, including a report by the Center for Biological Diversity, a report by its own Inspector General, a letter from 35 Congressional Representatives, and research pointing to the unavoidability of synergistic effects—the chemical combinations that cause greater effects when mixed together than the sum of the individual chemical effects. Despite all of the evidence that synergism is the rule rather than the exception, EPA’s consideration focuses on a narrow range of cases in which pesticide product patents make claims of synergy. Tell EPA to always investigate synergy and to determine need for pesticides. One such product is Dow’s Enlist Duo, which combines glyphosate and 2,4-D in an attempt to overcome weed resistance. The focus on products and tank mixes where synergism is a selling point brings to light the fact that as a rule, EPA does not request efficacy data in registering pesticides not intended to protect public health. Thus, although required by law to weigh pesticide risks and benefits, EPA rarely has data to make […]
