(Beyond Pesticides, June 7, 2019) Fruit orchards and vineyards endure some of the most intensive chemical management in all of agriculture. What has not been investigated — until now — is how pesticide drift from such agricultural sites may be affecting nearby public spaces. A recent, first-of-its-kind study out of northern Italy tested 71 public playgrounds near to apple orchards and vineyards in four valleys of the North Tyrol, and finds that 45% are contaminated with a single pesticide, and 24% by more than one. Study authors note that the playground contamination will likely grow worse over the course of the growing season. This would likely amplify the impacts of such chemical trespass on nearby public spaces, never mind the varieties of harm to the sites themselves and the food produced on them. Organic agriculture, of course, remedies all these concerns. The study randomly chose 71 public playgrounds in the four South Tyrolean regions, and analyzed grass samples for potential contamination by 315 different pesticides. Because pesticides applied to agricultural fields, orchards, and vineyards are easily volatized, carried aloft by wind, and/or washed by rain off of the target site, the study also evaluated the impacts of those (and other) factors […]

(Beyond Pesticides, June 4, 2019) A class-action lawsuit is accusing Starbucks stores in New York of misusing a highly toxic, carcinogenic pesticide near food, putting the health of customers and employees at risk.  “Stores throughout Manhattan have for many years been permeated with a toxic pesticide called Dichlorvos [DDVP], which is highly poisonous and completely unfit for use in proximity to food, beverages and people,” the suit reads. According to the lawsuit, Hot Shot brand No Pest Strips were placed in food areas in violation of labels that prohibit the pesticide’s use in “the food/feed areas of food/feed processing or food/feed manufacturing or food/feed service establishments.” A pest control operator found the illegally placed products on a number of separate occasions, hidden under bagels or in pastry display cases, during a five year period from 2013 to 2018. This was not at only one location, but appeared to be a common occurrence at nearly every one of the 100+ stores serviced by the pest control operator. The case brings to light a number of issues with the use of synthetic pesticides. The unsanitary conditions permitted to persist within Starbucks stores, per the pictures provided in the suit (see page 14), […]

(Beyond Pesticides, May 23, 2019) Glyphosate weed killers may be contributing to the growing worldwide epidemic f non-alcoholic fatty liver disease (NAFLD), a condition that causes swelling of the liver, and can eventually lead to cirrhosis, cancer, or liver failure. Researchers at the University of California (UC) San Diego found that higher levels of glyphosate detected in urine corresponded significantly with individuals that have also been diagnosed with NAFLD. Advocates are urging lawmakers at every level to respond to the accumulating science on the danger of glyphosate herbicides, ban their use, and adopt policy changes that put into place organic land management practices. “There have been a handful of studies, all of which we cited in our paper, where animals either were or weren’t fed Roundup or glyphosate directly, and they all point to the same thing: the development of liver pathology,” said Paul J. Mills, PhD, professor and chief in the Department of Family Medicine and Public Health at UC San Diego School of Medicine in a press release. “So I naturally thought: ‘Well, could it be exposure to this same herbicide that is driving liver disease in the U.S.?’” Dr. Mills and his team received urine samples from […]

(Beyond Pesticides, May 20, 2019) The bans of chlorpyrifos in three important agricultural states show the support for a ban of the chemical nationwide. Hawai’i banned chlorpyrifos a year ago with a unanimous vote of the legislature. New York and California banned it this month. States have been pursuing bans since the Environmental Protection Agency rescinded its proposed ban in 2017. Tell Your Governor to Ban Neurotoxic Pesticides and Support Organic; Send Thanks to Your Governor in Hawai’i, New York, and California Like other organophosphate pesticides, chlorpyrifos has been linked to damaging and often irreversible health outcomes in workers, pregnant women, and children. A widely used pesticide, agriculture companies annually spray six million pounds on crops like citrus, apples, and cherries.  In the same family as Sarin gas, the substance was initially developed prior to World War II as a chemical weapon. It can overstimulate the nervous system to cause nausea, dizziness, and confusion. With very high exposures (accidents or spills), it can cause respiratory paralysis and even death. When applying the chemical to fields, workers must wear protective garments such as respirators. Workers are then blocked from entering the fields from 24 hours up to 5 days after application due to the chemical exposure risk. A group of leading toxics […]

(Beyond Pesticides, May 15, 2019) On Monday, a California jury awarded plaintiffs in the third federal Roundup case over $2 billion in punitive and compensatory damages. The jury found that Monsanto “engaged in conduct with malice, oppression or fraud committed by one or more officers, directors or managing agents of Monsanto.” Plaintiffs Alva and Alberta Pilliod, a married couple in their seventies, used Roundup weed killer since the 1970s to maintain their yard and other owned properties. The couple did not wear protective gear when using Roundup because Monsanto marketed the product as “safe.” Alva was diagnosed with non-Hodgkin’s lymphoma (NHL) in 2011; Alberta’s diagnosis followed in 2015. The Pilliod v. Monsanto jury came to their decision based on evidence, not only of the herbicide’s carcinogenicity, but also of Monsanto’s role in suppressing and discredit.ing independent findings regarding Roundup toxicity. In an interview with U.S. Right to Know’s Carey Gillam, co-lead trial counsel Michael Miller said, “Unlike the first two Monsanto trials, where the judges severely limited the amount of plaintiffs’ evidence, we were finally allowed to show a jury the mountain of evidence showing Monsanto’s manipulation of science, the media and regulatory agencies to forward their own agenda despite […]

(Beyond Pesticides, May 9, 2019) On Wednesday, the U.S. Environmental Protection Agency (EPA) issued a proposed interim decision on glyphosate’s registration review, ignoring widespread scientific consensus on the herbicide’s carcinogenicity and instead restating the agency’s firm position that glyphosate is “not likely to be carcinogenic to humans.” EPA’s bold statement stands in stark contrast to scientific consensus to the contrary. In 2015, the World Health Organization’s International Agency for Research on Cancer (IARC) found glyphosate to be a probable human carcinogen. In response to resistance from the European Food Safety Authority, 94 expert scientists published an article in support of IARC’s methodologies and findings. Since 2015, several more publications have added significant weight to the body of evidence supporting glyphosate’s carcinogenicity. A February 2018 meta-analysis of studies on glyphosate suggested “a compelling link between exposures to GBH [glyphosate-based herbicides] and increased risk of NHL [non-Hodgkin lymphoma]. A February 2019 University of Washington study found that glyphosate increased the risk of non-Hodgkin lymphoma by as much as 41%. Despite attempts by current and former EPA top officials to “kill” their report, Agency for Toxic Substances and Disease Registry (ATSDR), a agency at the U.S. Department of Health and Human Services, released its […]

(Beyond Pesticides, May, 7, 2019) Last week, the New York State legislature voted to phase out and eventually ban the use of the neurotoxic insecticide chlorpyrifos. The vote, 44-18 in the state Senate and 94-50 in the Assembly, is still awaiting the Governor’s signature, who is expected to sign the measure. As evidence of harm continues to accumulate, scientists have called for a ban, and a legal case works its way through the courts, pressure is mounting on the U.S. Environmental Protection Agency (EPA) to once and for all remove this harmful pesticide from use. New York’s legislation sets implementation dates that leapfrog a similar law banning chlorpyrifos that passed in Hawai’i last year. Although Hawai’i’s law takes effect beginning in July of this year, the state may provide temporary use permits for the chemical until December 2022. New York also phases in restrictions, first prohibiting aerial applications beginning January 2020, then prohibiting all use except on apple trees starting January 2021. The chemical will be completely banned for use in New York in December 2021. Chlorpyrifos is a highly toxic insecticide that has been linked to damaging and often irreversible health outcomes, particularly for pregnant mothers and their children, […]

(Beyond Pesticides, May 2, 2019) Researchers have documented an increase in food and drinking water residues of neonicotinoids, insecticides linked to breast cancer. Using the Pesticide Data Program (PDP), 1999-2015, of the U.S. Department of Agriculture, the researchers identified near-peak detection frequencies in 2015, after a decline from 2008-2013. Imidacloprid remains the most common neonicotinoid detected across imported commodities, while the neonicotinoids clothianidin, thiamethoxam, acetamiprid, and flonicamid are replacing imidacloprid in domestic production. Authors note that these newer neonicotinoids are potentially more toxic than imidacloprid, raising concerns for understudied human health and environmental impacts. The study, Trends in neonicotinoid pesticide residues in food and water in the United States, 1999–2015, published in the journal Environmental Health, finds the highest detection frequencies for neonicotinoids in drinking water, with 30% of treated drinking water turning out positive for imidacloprid in 2011. Certain fruits and vegetables are also frequently contaminated by neonicotinoids, with detection frequencies ranging from 20% to as high as 57% in the case of imidacloprid on cauliflower. While the study points to specific fruits and vegetables as posing higher risk, the main message reaches beyond individual commodity or individual neonicotinoid results. Authors uncover a systematic increase in detection of neonicotinoid […]

(Beyond Pesticides, May 1, 2019) Evidence of the dangers of glyphosate continues to mount: researchers at Washington State University have identified, in research that exposed pregnant rats to the compound, significant disease and pathology in subsequent generations. The rats were exposed, from day 8 through day 14 of gestation, to half the observable adverse effect level (NOAEL) of glyphosate. Although this study found negligible impacts on the pregnant rats themselves or on their first-generation offspring, dramatic increases in incidence of pathology showed up in the two subsequent generations, including reproductive (prostate and ovarian) and kidney diseases; obesity; and birth anomalies. The study, published in the journal Scientific Reports (an open access, multidisciplinary journal from Nature Research), and conducted by Michael Skinner, Ph.D. and five colleagues, is the first to assess the potential transgenerational impacts of glyphosate in mammals. Its results point to an emerging frontier in assessing the risks of glyphosate and other toxic chemicals, and add to the urgent and growing demand that the use of this particular toxic — and pervasive — pesticide be halted. The research team was interested in looking at possible transgenerational impacts of glyphosate in part because of its ubiquity: it is one of the […]

(Beyond Pesticides, April 26, 2019) Research by the youth participatory action team of the CHAMACOS of the Salinas Evaluating Chemicals in Homes and Agriculture (COSECHA) reveals that teenagers in the Salinas Valley, California are routinely exposed to concerning levels of multiple toxic pesticides, several of them known endocrine disruptors. In an interview with Kion News, COSECHA research director Kimberly Parra remarked that the study is especially important because teenagers are in a stage of rapid reproductive development. As the study authors emphasize, it is their developmental stage that makes teenagers more vulnerable to the effects of endocrine disrupting pesticides, with potentially devastating consequences for lifelong health. The COSECHA study quantifies exposure to 72 pesticides, captured through volatile-trapping silicone wristbands, across 97 teenage girls living in various areas of the Salinas Valley region. Of the 72 pesticides analyzed, authors report that subjects are exposed to as many as 20 and an average of 8 pesticides over one week of routine indoor and outdoor activity. Given the well-documented dangers of pesticide co-exposures, these multiple-exposure findings are particularly concerning. Ranking the highest for prevalence among the studied pesticides is fipronil sulfide, a breakdown product of the insecticide fipronil, detected in 86.6% of the analyzed wristbands. […]

(Beyond Pesticides, April 24, 2019) On April 19, the U.S. Court of Appeals for the 9th Circuit ordered the U.S. Environmental Protection Agency (EPA) to provide a justification for why chlorpyrifos, a neurotoxic insecticide commonly used in agriculture, should remain in the U.S. market. The EPA has 90 days to comply. Chlorpyrifos has been linked to damaging and often irreversible health outcomes in workers, pregnant women, and children. Low levels of exposure early in life can lead to increased risk of learning disabilities including lowered IQ, developmental delay, and attention deficit/hyperactivity disorder (ADHD). Farmworkers and their children are disproportionately affected by the use of this chemical because they are exposed at work, home, and even at school. “While we are moving forward, the tragedy is that children are being exposed to chlorpyrifos, a pesticide science has long shown is unsafe,” said Earthjustice Attorney Patti Goldman in a statement. “We hope Trump’s EPA finally decides to protect the future of countless children and the health of millions of farmworkers.” The battle against chlorpyrifos has been long and drawn out, though there has been significant movement in the last few months. Beyond Pesticides has put together a brief timeline of events: A […]

(Beyond Pesticides, April 4, 2019)  Following on its verdict that the herbicide Roundup caused plaintiff Edwin Hardeman’s  non-Hodgkin lymphoma (NHL), the jury on March 27 issued an award of $80 million—$5 million in compensatory damages and $75 million in punitive damages—for improper labeling and negligence on the part of the manufacturer and defendant, Monsanto. The trial, the first federal Roundup cancer trial, marks the first of a multidistrict litigation against Monsanto, with more than 1,600 similar lawsuits pending in San Francisco’s federal court. The jury’s second verdict affirmed Mr. Hardeman’s allegations that Roundup’s design is defective and lacks sufficient warnings, and that Monsanto was negligent by not using reasonable care to warn about Roundup’s NHL risk. The Edwin Hardeman v. Monsanto Co. jury verdict marks the second multi-million dollar award to be granted in a landmark case against Bayer/Monsanto within the past year. Last August in San Francisco Superior Court, California groundskeeper Dewayne “Lee” Johnson was awarded $39 million in compensatory damages, and $250 million in punitive damages in the first case that linked his NHL to Monsanto’s glyphosate/Roundup. In October, the judge in the case upheld the verdict, but reduced the award to $78 million. Mr. Hardeman is represented by […]

(Beyond Pesticides, March 27, 2019) Exposure to commonly used pesticides in the womb and during the first year of life is linked to a higher risk of developing autism, according to the study, “Prenatal and infant exposure to ambient pesticides and autism spectrum disorder in children: population based case-control study,” published in the journal BMJ last week. Although the study does not reveal a causal link, it adds to previous literature highlighting autism risks from pesticide exposure, and reinforces calls to limit pesticide exposure during early life critical windows of vulnerability. The authors note their findings “support the need to avoid prenatal and infant exposure to pesticides to protect the developing child’s brain.” Researchers used data from California’s records of autism disorder diagnosis and birth rates from 1998 to 2010. Roughly thirty-five thousand healthy patients acted as a control, while scientists identified nearly three thousand patients with an autism diagnosis, of which 445 also displayed a co-occurring intellectual disability. Data was then drawn from California’s pesticide use recording database, and eleven pesticides (glyphosate, chlorpyrifos, diazinon, acephate, malathion, permethrin, bifenthrin, methyl bromide, imidacloprid, avermectin, and myclobutanil) were analyzed for their use within 2000 meters (1.25 miles) of the homes of those […]

(Beyond Pesticides, March 26, 2019) In a study investigating the carcinogenic effects of pesticide exposure by analyzing data on 316,270 farmers and farmworkers in the U.S., Norway, and France, researchers have identified elevated risk for non Hodgkin lymphoma (NHL) and some subtypes, linking glyphosate and large B-cell lymphoma. Other pesticides linked to the disease include the pyrethroid deltamethrin and chronic lymphocytic leukemia/small lymphocytic lymphoma; and terbufos and NHL overall. Researchers also found “inverse associations of NHL overall with the broader groups of organochlorine insecticides and phenoxy herbicides, after adjusting for exposure to other pesticides”; such inverse associations were not found with active ingredients within these groups. The research underscores how complex the science of pesticide impacts on human health, and on cancer incidence, can be. To wit: in evaluating 14 different pesticide categories and 33 individual, active chemical ingredients, Maria E. Leon, et al., conclude that associations of pesticides with the development of NHL appear to be (NHL) subtype- and chemical-specific. Published in the International Journal of Epidemiology in mid-March, the study, “Pesticide use and risk of non-Hodgkin lymphoid malignancies in agricultural cohorts from France, Norway and the USA: a pooled analysis from the AGRICOH consortium,” uses data from three large cohort […]

(Beyond Pesticides, March 20, 2019) In a second verdict against Bayer/Monsanto yesterday, a jury found unanimously that a California man’s non Hodgkin lymphoma (NHL) was substantially caused by the herbicide glyphosate (Roundup). The case being heard in federal court in San Francisco now moves to the damages phase. Last August in San Francisco Superior Court, a California groundskeeper was awarded $39 million in compensatory damages, and $250 million in punitive damages in a case that linked his NHL to Monsanto’s glyphosate/Roundup. In October, the judge in the case upheld the verdict, but reduced the award to $78 million. According to the Associated Press, the trial judge, U.S. Judge Vince Chhabira “is overseeing hundreds of Roundup lawsuits and has deemed [this case] and two others ‘bellwether trials.“ The case was brought by Edwin Hardeman of Santa Rosa, CA. He said he had been using Roundup since the 1980’s. During the trial, according to The Guardian, Judge Chhabria, “approved Monsanto’s request to prohibit Hardeman’s attorneys from raising allegations about the corporation’s conduct, saying issues about its influence on science and government were a ‘significant … distraction.’” This set up a limitation that required the plaintiff’s attorneys to focus solely on studies linking the chemical to cancer […]

(Beyond Pesticides, March 7, 2019) A publication in the journal Environmental Health Perspectives highlights findings from a recent study showing that environmental concentrations of the neonicotinoid insecticides thiacloprid and imidacloprid increase expression of a gene linked to hormone-dependent breast cancer. Authors of the featured study uncovered a pathway through which neonicotinoids stimulate excess estrogen production, known to occur during the development of progressive hormone-dependent breast cancer. In the words of the authors, “Our findings highlight the need for further research to assess the potential impacts of low-dose and chronic exposure to neonicotinoids on endocrine processes affecting women’s health.” The study, published in Environmental Health Perspectives in April 2018 by researchers at the University of Quebec, is not the first to point to a potential link between neonicotinoid exposure and breast cancer. A 2015 study by the same research group revealed that the neonicotinoids thiacloprid and thiamethoxam, along with the herbicide atrazine, induce similar effects in breast cancer cells. In both studies, exposure to neonicotinoids alter promoter activity to induce heightened production of the enzyme aromatase, which is known to stimulate estrogen production and thereby cancer cell proliferation. The recently published study, authored by Silke Schmidt, PhD, brings greater urgency to […]

(Beyond Pesticides, March 5, 2019) Wild, edible plants subject to drift from the herbicide glyphosate during forestry operations can be contaminated with the chemical an entire year after an initial application, according to a new study published in the Canadian Journal of Forest Research. Glyphosate is often used in forestry to knock down unwanted trees, shrubs, and other plants after clear-cutting to provide room for the regrowth of trees deemed valuable. However, this new research shows that “non-target” species, such as raspberries and blueberries, eaten by wildlife and sometimes wild foraged by humans can retain significant levels of glyphosate contamination due to drift and overspray. Forester Lisa Wood, PhD, from the University of Northern British Columbia began this research based on input and requests from Canadian indigenous First Nations communities. Back in 2013, shrubs foraged by traditional berry-pickers in northeastern British Columbia were sampled and found to contain glyphosate residues, leading to the need for a broader investigation. Dr. Wood sampled the roots and shoots of 10 plant species from an area that had been aerially sprayed with glyphosate a year prior as part of forestry operations to clear aspen and make room for coniferous re-plantings. The 10 plants, which […]

(Beyond Pesticides, March 1, 2019) The costs of pesticide use extend far beyond the invoices farmers pay for purchase of the chemicals to use on their crops. The real costs related to pesticide use and exposure include those of health care, lost productivity and income, and environmental damage (loss of environmental services and biodiversity; compromised air, water, and soil quality). There has been relatively little research focused on those real and extensive costs; this Daily News Blog turns its attention to several that have made the attempt. January 2019 saw the publication of a new book, Sicker Fatter Poorer: The Urgent Threat of Hormone-Disrupting Chemicals to Our Health and Future … and What We Can Do About It, by Leonardo Trasande, MD, MPP, which examines how some chemicals — including organophosphate and organochlorine pesticides — disrupt human endocrine (hormonal) function, and damage health, sometimes irreparably. The book further investigates the economic costs of associated diseases and other health problems to the U.S. economy — on the order of 2.3% of GDP (gross domestic product), or $340 billion, annually. As Dr. Trasande notes, “The reality is that policy predicts exposure, exposure predicts disease and disease ultimately costs our economy.” Dr. Trasande is […]

(Beyond Pesticides, February 28, 2019) Earlier this month, a team of U.S. scientists published a meta-analysis of studies on glyphosate-based herbicides (GBH), concluding that the evidence “suggests a compelling link between exposures to GBH and increased risk of NHL [non-Hodgkin lymphoma],” corroborating findings by the International Agency for Research on Cancer. The analysis, authored by researchers from University of California, Berkeley, University of Washington, Seattle, and the Icahn School of Medicine at Mount Sinai, New York, is the latest to support the conclusions established by the International Agency for Research on Cancer that products containing glyphosate pose a cancer risk to humans. As research continues to accumulate on the risks posed by this chemical, the case for transitioning to less toxic alternatives to safeguard public health is becoming increasingly urgent. Researchers took every available published human study on NHL and glyphosate, including the most recently updated data from the ongoing U.S. Agricultural Health Study (AHS), in conducting their review. Focus was put on individuals within these studies exposed to the highest amounts of glyphosate. The reasoning, researchers indicate, is that if there is a true association between glyphosate and a health outcome like cancer, exposures to higher amounts for a longer […]

(Beyond Pesticides, February 20, 2019) Women exposed to DDT during ‘early windows of susceptibility’ in their childhood are at increased risk of developing breast cancer, according to new research published in the Journal of the National Cancer Institute. Nearly 75 years after the chemical was first used in the U.S., and 50 years after its ban, DDT is continuing to adversely affect the health of Americans. The data brings needed attention to the dangers of early-life pesticide exposure, and underlines the need to take a precautionary approach to the introduction of biocides in our environment so that future generations do not suffer from the same mistakes of the past. “What we have learned is that timing really matters. We know that if harmful exposures occur at times when breast tissue is rapidly changing, such as during puberty, they impact breast development in ways that can later result in cancer,” said lead author Barbara A. Cohn, PhD, of the Public Health Institute’s (PHI) Child Health and Development Studies. “The research published today suggests that DDT affects breast cancer as an endocrine disruptor, that the period of time between first exposure and cancer risk seems to be around 40 years–and that other […]

(Beyond Pesticides, February 6, 2019) The American Association for the Advancement of Science (AAAS) has awarded two researchers the group’s Scientific Freedom and Responsibility Award for their work uncovering the link between glyphosate and chronic kidney disease (CKD), which has killed at least 25,000 Sri Lankans and 20,000 Central Americans. Award recipients Sarath Guanatilake, MD, and Channa Jayasumana, PhD, faced death threats and claims of research misconduct as they went toe to toe with agrichemical industry giant Monsanto (now Bayer’s Monsanto), the major manufacturer of glyphosate-based products like Roundup. “To right a wrong when significant financial interests are at stake and the power imbalance between industry and individual is at play takes the unique combination of scientific rigor, professional persistence and acceptance of personal risk demonstrated by the two scientists recognized by this year’s award,” says Jessica Wyndham, director of the Scientific Responsibility, Human Rights and Law Program at AAAS. In the mid-90s, reports began to emerge of Sri Lankan rice farmers – many otherwise healthy, young adults, succumbing to CKD. Dr. Gunatilake, a researcher at California State University, Long Beach (CSULB), was hired by the Sri Lanka Ministry of Health to investigate the cause of the disease. Around the […]

(Beyond Pesticides, February 5, 2019) Linuron, an herbicide registered for use by the U.S. Environmental Protection Agency (EPA), yet recently banned in Europe due to health concerns, appears to trigger inflammatory signals that have been linked to the onset of Multiple Sclerosis (MS). This new evidence, published in the journal Cell by researchers at Brigham and Women’s Hospital in Boston, MA, indicates that exposure to chemicals and pesticides in the environment may be a risk factor in the development of neurodegenerative diseases. “We created a platform to systematically investigate the understudied effects of environmental exposures,” said study coauthor Francisco Quintana, PhD. “The goal of our work is to return results that can guide future epidemiological studies and identify actionable targets.” Researchers began their investigation with 976 chemicals identified by EPA’s ToxCast program, an inventory of compounds that have undergone screening for a battery of laboratory tests. Within that inventory, 75 chemicals, including linuron, were found to interfere with the signaling pathways linked to MS. To confirm the adverse impacts, scientists used the embryos of zebrafish, animals often used as models in laboratory research. The zebrafish embryos were altered to contain low levels of myelin, a protein that protects nerve cells, as […]

(Beyond Pesticides, January, 23, 2019) Individuals that have been acutely poisoned by pesticides at some time in their life may be more likely to lose their sense of smell, according to a recent study published in Environmental Health Perspectives.  Researchers focused on the effect of high pesticide exposure events (HPEE), such as a pesticide spill or other incident, on a farmers’ ability to smell later in life. This is the first study to indicate pesticide exposure may result in olfactory impairment. Farmers from Iowa and North Carolina enrolled in an ongoing U.S. Agricultural Health Study have been asked about their pesticide use roughly every 5 to 6 years since 1993. In the most recent survey, taken from 2013-2015, farmers were asked additional questions about HPEE in their lifetime and whether they had a significantly decreased or impaired sense of smell. “Studying farmers gives us more reliable data on pesticide exposures than if we had studied the general population,” says Honglei Chen, MD, PhD, lead author and professor of epidemiology at Michigan State University in a press release. “Because they use pesticides more and it’s part of their job, they’re more likely to remember what pesticides they used and in cases […]
