(Beyond Pesticides, December 2, 2021) A study published in Cellular Physiology and Biochemistry finds atrazine (ATR) exposure worsens lung disease outcomes in individuals with idiopathic (spontaneous) pulmonary fibrosis (IPF), a group of incurable lung diseases involving damaged/scarred lung tissue. Furthermore, chemotherapeutic products used to treat lymphoma (immune system cell cancer) like bleomycin can induce pulmonary fibrosis complications exacerbated by pesticide exposure. However, pesticide-related pulmonary fibrosis can have implications for neurological health, such as motor function. Scientific literature already finds an association between pesticide exposure and respiratory illnesses such as asthma, lung cancer, and chronic obstructive pulmonary disease (chronic bronchitis). Although IPF impacts over 5 million people a year globally, the disease is difficult to predict, which is concerning as the death rate is 50 to 56 percent within the first few years. Therefore, studies like this highlight the significance of evaluating how pesticide exposure impacts respiratory function, especially when exposure to respiratory toxicants increases vulnerability to existing respiratory-fixated illnesses like Covid-19. Advocate have urged the U.S. Environmental Protection (EPA) to incorporate scientific findings that these—where chemical exposures exacerbate an existing medical condition—into its pesticide registration review program. Researchers note, “[O]ur data represent an addition to the complex information on ATR-induced pulmonary toxicity. In particular, in this […]

(Beyond Pesticides, November 30, 2021) The chronicle of developments in the glyphosate saga has just grown longer: the California Supreme Court has rejected a request by Bayer AG for review of the August 2021 First District Court of Appeal (San Francisco) ruling, for the plaintiffs, that Monsanto knowingly marketed a product — Roundup — whose active ingredient (glyphosate) could be dangerous. The $87 million in damages awarded to the plaintiffs in the litigation, Alberta and Alva Pilliod, has thus survived Bayer’s challenge. This highest state court decision racks up another loss for Bayer (which now owns the Monsanto “Roundup” brand) — despite its dogged insistence, throughout multiple lawsuits (with many more still in the pipeline), that glyphosate is safe. Beyond Pesticides has covered the glyphosate saga extensively; see its litigation archives for multiple articles on glyphosate lawsuits. Glyphosate has been the subject of a great deal of public, advocacy, and regulatory attention, as well as the target of thousands of lawsuits — particularly since the 2015 declaration by the IARC (International Agency for Research on Cancer) that the compound is a likely human carcinogen. In June 2020, facing approximately 125,000 suits for Roundup’s role in cancer outcomes, Bayer announced a $10 billion […]

  (Beyond Pesticides, November 24, 2021) On Thanksgiving, thank you for being a part of Beyond Pesticides and sharing and contributing to the vision necessary to protect the web and fragility of life. We believe that there is no time like Thanksgiving to think about how we can more effectively join together as families and communities across divisions and different points of view to find a common purpose in protecting the health of the environment and all that inhabit it. Unfortunately, there are a host of pesticides, genetically engineered materials, and others in conventional Thanksgiving foods that not only impact human health, but threaten the environment. With far too many adverse health and ecological effects associated with toxic chemicals, organic practices are viable solutions to mitigate pesticide contamination and subsequent exposure. Read on as we consider the range of challenges we must confront, and the solutions that can bring us all together. The Climate As climate impacts grow, an increase in uses of synthetic pesticides in agriculture is likely — because of waning efficacy (pesticide resistance) of these compounds, and mounting pest pressure (i.e., increasing insect population and metabolism). Production of pesticides contributes to greenhouse gas emissions gas (e.g., nitrous […]

(Beyond Pesticides, November 23, 2021) The U.S. Environmental Protection Agency (EPA) announced, in mid-October, a revision of its guidance on the evaluation of antimicrobial pesticides used against Candida auris (C. auris). This pathogen is a type of fungus (a yeast) that can cause serious infection, and can spread readily among patients and staff in hospitals and other congregate healthcare settings (such as nursing homes). C. auris has developed resistance to what used to be the therapeutic impacts of major antifungal medications. (Resistance is a major and growing problem in healthcare and in agriculture, with the latter exacerbating the former.) Another moving part in this unholy development of “chemical compounds no longer working” is EPA’s failure to assess the efficacy of any pesticides that are not used for public health purposes; for example, EPA evaluates the efficacy of only those antimicrobial compounds whose use patterns classify them as human-health-related. This failure to evaluate efficacy of all other pesticide products leaves many people in the dark about whether what they may be using actually works — never mind the potential risks associated with that use. The antifungal medications that have been used for many years to treat Candida infections often no longer work for C. auris; […]

(Beyond Pesticides, November 19, 2021) Thanksgiving offers an opportunity for people to come together and give thanks for the bounty of an organic harvest. Unfortunately, many Thanksgiving meals are produced by chemical farming practices that utilize hazardous pesticides, genetically engineered (GE) crops, and petroleum-based synthetic fertilizers. These inputs, apart from being unnecessary, degrade ecosystems and affect the health of consumers and agricultural workers alike. It’s never too late to start a new tradition – for this year and into the future, make your Thanksgiving feast sustainable by going organic. Now, more than ever, it’s important to go organic: For Our Own Health Going organic drastically reduces the amount of pesticide in a person’s body. Although Thanksgiving is generally no time to think about dieting, we’ll aim to make it instructive: recent research finds that one of the biggest health benefits of the Mediterranean Diet comes when you go organic. Compared to individuals on a Mediterranean diet filled with chemically farmed foods, those that ate organic had 91% lower pesticide residue. This finding is backed up by a considerable body of prior research. A 2015 study based on self-reported food intake found that those who eat organic generally have much lower […]

(Beyond Pesticides, November 12, 2021) Omnivorous readers may have encountered an article, in the November 15 issue of The New Yorker magazine, titled — at best misleadingly, and certainly sensationally — “The Great Organic-Food Fraud.” The subhead comports with the tone of the headline: “There’s no way to confirm that a crop was grown organically. Randy Constant exploited our trust in the labels — and made a fortune.” The piece, by Ian Parker, tells a complex tale of the machinations of dishonest and greedy people who saw, in the commerce in organic grains, an opportunity to misrepresent nonorganic crops as organic and make a boatload of money in doing so. What the article fails to do is render any comprehensive picture of how National Organic Program certification and inspection work, and the underlying principles, values, and standards in federal law (the Organic Foods Production Act), nor does it review either the benefits of organic agriculture broadly or the massive harmful impacts of conventional, chemical-intensive agriculture in the U.S. Beyond Pesticides provides ballast, in this Daily News Blog article, to the failings of the New Yorker article and the damage it might do to the organic movement. It is worth noting […]

(Beyond Pesticides, November 11, 2021) Evidence is building that so-called ‘inert’ ingredients in pesticide formulations are harming pollinators and undermining regulatory determinations that designate products as ‘bee-safe.’ According to a new study published in Scientific Reports, the fungicide Amistar causes lethal and sublethal effects that can be primarily attributed not to its active ingredient azoxystrobin, but to alcohol ethoxylates, a co-formulant, or inert ingredient intentionally added to a pesticide formulation. While the U.S. Environmental Protection Agency (EPA) utilizes a ‘bee advisory box’ on pesticide labels to indicate danger to pollinators, results of this and previous studies on inert ingredients underline how EPA’s ‘cute little bee icon’ is little more than window dressing for massive regulatory failures and a pollinator crisis that has shown no signs of abating. Scientists at Royal Holloway University in London, UK began their study with three packaged colonies of Bombus terrestris, a European bumblebee often bred for commercial use in greenhouses throughout the world. In order to suss out differences in toxicity between the various ingredients in the formulated Amistar fungicide, bees were separated into multiple groups. One group acted as a positive control, and was dosed with dimethoate, a pesticide known to be highly toxic […]

(Beyond Pesticides, November 9, 2021) Replacing a modern, ‘western’ diet of highly processed foods with a Mediterranean diet filled with conventional, chemically-grown fruits and vegetables triples exposure to toxic pesticides, according to research recently published in The American Journal of Clinical Nutrition. However, this disturbing change can be eliminated by eating a Mediterranean diet consisting entirely of organic food, which is not sprayed with synthetic pesticides. The advantages of the Mediterranean diet, often ranked as the ‘best diet’ and emphasized by medical practitioners for its health benefits, now appear to depend on the production practices involved in the meals an individual eats. “There is growing evidence from observational studies that the health benefits of increasing fruit, vegetables and wholegrain consumption are partially diminished by the higher pesticide exposure associated with these foods,” said study coauthor Per Ole Iversen, MD. “Our study demonstrates that consumption of organic foods allows consumers to change to a healthier diet, without an increased intake of pesticides.” Researchers began their investigation by establishing a randomized trial consisting of 27 adults, all of whom were postgraduate student volunteers on a study abroad course in Greece. The experiment lasted a total of five weeks, including a two-week intervention in the […]

(Beyond Pesticides, November 8, 2021) California state agencies, led by the California Natural Resources Agency (CNRA), released a draft Natural and Working Lands Climate Smart Strategy to guide and accelerate near- and long-term climate action across key California landscapes. All states need such strategies, and to be effective, they must be backed by ambitious targets focused on reduction of pesticides and support for organic agriculture. Tell your state legislators and governor to adopt a Natural and Working Lands Climate Smart Strategy that supports organic agriculture and land management. (CALIFORNIA RESIDENTS: Please use this form.) A Natural and Working Lands Climate Smart Strategy will identify our natural and working lands as a critical yet currently underutilized sector in the fight against climate change. These lands can sequester and store carbon emissions, limit future carbon emissions into the atmosphere, protect people and nature from the impacts of climate change, and build resilience to future climate risks. Climate smart management of our natural and working lands also improves public health and safety, secures our food and water supplies, and increases equity. The strategy should define the state’s natural and working landscapes; describe how these lands can deliver on climate change goals; highlight priority nature-based climate […]

(Beyond Pesticide, November 4, 2021) A scientific literature analysis by the Federal University of Goias, Brazil, finds occupational (work-related) exposure to agricultural pesticides increases the risk for 45 different types of cancer. This analysis assesses studies from the last decade—2011 to 2020—to identify cancer risk associated with occupational exposure by country, pesticide type, and methods used to diagnose disease. Many pesticides are “known or probable” carcinogens (cancer-causing agents), and widespread uses only amplify chemical hazards, adversely affecting human health. However, research on cancer and pesticides lacks comprehensive information regarding human health effects associated with long-term chemical use. This study highlights the significant role that long-term research plays in identifying potential health concerns surrounding registered pesticides. The use of these xenobiotics (foreign chemical compounds) substances in agriculture are increasing. Thus, it is important those working with and around these toxicants have protection. The analysis notes, “Overall, then, the results of the present study emphasize the need to evaluate overuse of pesticides and the concomitant increase in the number of cancer cases. Future research should thus include active intervention in the correct use of pesticides by farmworkers and encourage adequate training and the use of PPEs [personal protective equipment], as well as routine periodic medical […]

(Beyond Pesticides, November 2, 2021) Cover crops create habitat that draw in pest predators and help mitigate crop injury, finds research published in the journals Agroecosystems and Biological Control from scientists at the University of Georgia. Expanded predator diversity can reduce pest pressure that drives conventional chemical farmers to apply toxic pesticides, and the authors of the study find the practice to be economically viable within these cropping systems. “There’s a motion of change going on where growers are thinking more about using natural systems instead of just using pesticides,” said co-author Jason Schmidt, PhD in a news release. “Producers must use all tools available to make a profit, so if they can promote beneficial insects in the system to aid in pest control,  fewer inputs are needed and that should lead to reduced costs of production. ” To determine how beneficial cover crops were to cotton production, researchers began with experimental crops established over two years in 2016 and 2017 in Georgia. Twelve cover crops plots were established with crimson clover and rye, while a plot not planted with cover crops was used as a control. Researchers planted the cover crop in early November after the previous cotton crop […]

(Beyond Pesticides, November 1, 2021) Join with 37 environmental and health groups, farm organizations, and beekeeper councils, who have delivered a letter to the Environmental Protection Agency (EPA) leaders seeking major reforms in the Office of Pesticide Programs (OPP). They provided a comprehensive list of OPP’s major failures as the lead federal office for pesticide regulation and management, including: Allowing chlorpyrifos to stay registered for more than 14 years after health experts and affected farmworkers petitioned for its removal based on its known neurological danger, Allowing unlimited use of Roundup (glyphosate) long after it was shown to contribute to deadly non-Hodgkin’s lymphoma in heavy users and it devastated the treasured monarch butterfly, now driven to near extinction in North America, Approving hundreds of neonicotinoid systemic insecticides, now the most widespread insecticide in the country where they are decimating honey and native bees and other key pollinators and beneficial species; and Registering dicamba in a highly volatile herbicide, a shocking blunder later overruled by a federal court ruling that stated OPP “not only substantially understated the risks …. It also entirely failed to acknowledge other risks, including those it was statutorily required to consider.” Take action: Tell EPA and Congress that the […]

(Beyond Pesticides, October 28, 2021) A study published in Frontiers in Environmental Science finds the popular herbicide glyphosate negatively affects microbial communities, indirectly influencing plant, animal, and human health. Exposure to sublethal concentrations of glyphosate shifts microbial community composition, destroying beneficial microorganisms while preserving pathogenic organisms. Glyphosate is the most commonly used active ingredient worldwide, appearing in many herbicide formulas, including Bayer’s (formerly Monsanto) Roundup®. The use of this chemical has been increasing since the inception of crops genetically modified to tolerate glyphosate over two decades ago. The toxic herbicide readily contaminates the ecosystem with residues pervasive in both food and water commodities. In addition to this study, the scientific literature commonly associates glyphosate with human, biotic, and ecosystem harm, as a doubling of toxic effects on invertebrates, like pollinators, has been recorded since 2004. The authors caution, “[O]utbreaks of several animal and plant diseases have been related to glyphosate accumulation in the environment. Long-term glyphosate effects have been underreported, and new standards will be needed for residues in plant and animal products and the environment.” With an increasing number of reports on the relationship between glyphosate and human health, including potential effects on the human gut microbiome, advocates are calling on global leaders to eliminate chemical […]

(Beyond Pesticides, October 21, 2021) A study published in Environment International finds higher rates of various cancers among agricultural workers, with multiple myeloma (blood cancer) and melanoma (skin cancer) disproportionately impacting female farmers. Although research studies link cancer risk to genetic and external factors (e.g., cigarette smoke), there are increasing reports and scientific studies that pesticide exposure augments the risk of developing common cancers like melanoma and less common cancers like multiple myeloma. This study highlights the importance of understanding how pesticide use can increase the risk of latent diseases, which do not immediately develop upon initial exposure. The researchers note, “Given the large size of the agricultural population worldwide and the presence of various potential hazards in its working environment, such epidemiological data are important in improving occupational health measures and ensuring better workers’ health.” To investigate the cancer incidence patterns, researchers evaluated data from the AGRICOH database involving various international studies. The studies assessed pesticide exposure scenarios, which researchers use to determine the etiological (causal) agent of cancer incidences among farmers relative to the general population. Researchers analyzed data from eight different AGRICOH groups in various countries: France (AGRICAN), the U.S. (AHS, MESA), Norway (CNAP), Republic of Korea (KMCC), Denmark […]

(Beyond Pesticides, October 19, 2021) Exposure to the insecticide malathion increases risk of developing chronic kidney disease (CKD), according to a study recently published in the International Journal of Environmental Research and Public Health. According to study co-author Nicholas Osborne, PhD, CKD is on the rise in developing countries in Southeast Asia and Central America, and, “[n]early one in 10 people in high income countries show signs of CKD, which is permanent kidney damage and loss of renal function.” Although CKD risk increases with age, and is associated with other health factors like smoking, heart disease, and diabetes, cases without clear cause are increasingly common, indicating the that environmental factors are likely playing a role. Researchers began with data drawn from the United States’ National Health and Nutrition Examination Survey (NHANES), an ongoing study that assesses Americans’ health and nutritional status through interviews, physicals, and other health tests. Urine samples taken from individuals enrolled in NHANES 2001-2004 and 2007-2010 (tests within years between these dates did not analyze specific pesticides) were reviewed for the presence of pesticides, and compared against data collected on kidney function. In addition to malathion, 2,4-D, chlorpyrifos, and 3-PBA, the major metabolite for most synthetic pyrethroid insecticides, […]

(Beyond Pesticides, October 18, 2021) The most recent science on pesticides raises serious health and environmental effects associated with pesticide use for lawn and landscape management. While the data is often not assembled in one place, updated factsheets bring together the science on the 40 commonly used pesticides used for conventional landscape management. Governors have the authority to stop the use of these hazardous materials that are used on parks and playgrounds, either by executive order or through their work with their state legislature, and transition land management to organic practices. Tell your governor to stop hazardous pesticide use on state lands and transition to organic land management. The new factsheets document with scientific citations a wide range of diseases and ecological effects linked to pesticides. The underlying analysis supporting the adverse health and environmental effects identified in the factsheets are based on toxicity determinations in government reviews and university studies and databases. What do the factsheets disclose? Of the 40 most commonly used lawn and landscape pesticides, in reference to adverse health effects… 26 are possible and/or known carcinogens 24 have the potential to disrupt the endocrine (hormonal) system 29 are linked to reproductive effects and sexual dysfunction 21 […]

Health and environmental effects disclosed on factsheets to guide community decisions on lawn and landscape management that do not poison people and contaminate the environment. WASHINGTON, D.C. (October 14, 2021) — Today, the national environmental and public health group Beyond Pesticides is releasing its health and environmental effects factsheets for “40 Commonly Used Lawn Pesticides,” updating and expanding on previous factsheets on 30 pesticides. These comprehensive factsheets documents with scientific citations a wide range of diseases and ecological effects linked to pesticides. The underlying analysis supporting the adverse health and environmental effects identified in the factsheets are based on toxicity determinations in government reviews and university studies and databases. What do the factsheets disclose? Of the 40 most commonly used lawn and landscape pesticides, in reference to adverse health effects, 26 are possible and/or known carcinogens, 24 have the potential to disrupt the endocrine (hormonal) system, 29 are linked to reproductive effects and sexual dysfunction, 21 have been linked to birth defects, 24 are neurotoxic, 32 can cause kidney or liver damage, and 33 are sensitizers and/or irritants. Regarding adverse environmental effects, 21 are detected in groundwater, 24 have the ability to leach into drinking water sources, 39 are toxic to […]

(Beyond Pesticides, October 13, 2021) Pesticide use in conventional chemical-intensive farming is so pervasive that weeds are developing resistance to herbicides they have never encountered before. According to research published in Plant and Cell Physiology and New Phytologist, the notoriously difficult-to-control weed waterhemp (Amaranthus tuberculatus) is outpacing commercial crops in its ability to detoxify after herbicide exposure. “This is probably the first known example where waterhemp has evolved a detox mechanism that a crop doesn’t have. It’s using a completely different mechanism, adding to the complexity of controlling this weed,” says Dean Riechers, PhD, study co-author and professor at University of Illinois. Researchers found waterhemp resistant to the chemical syncarpic acid-3 (SA3). SA3 is one of the earliest versions of a 4-Hydroxyphenylpyruvate dioxygenase (HPPD) inhibiting herbicide. HPPD inhibiting herbicides, which include herbicides like isoxaflutole and mesotrione, are selective (ie plant-specific) and break down amino acids that are required for plant growth and development. Corn generally tolerates HPPD-inhibiting chemicals, detoxifying them through different channels depending upon the specific type of HPPD herbicide. Weeds that grow in and around corn fields where these chemicals are regularly sprayed, like waterhemp, have likewise evolved the ability to detoxify HPPD-inhibitors, mostly mimicking the process that […]

(Beyond Pesticides, October 8, 2021) Taking a page from the playbook of Trump Administration Secretary of Agriculture Sonny Perdue, the current secretary, Tom Vilsack, used a September G20 summit in Italy to target the European Union’s “Farm to Fork” (F2F) strategy, a part of its European Green Deal. Mr. Perdue had said that F2F is “more . . . ‘political science’ than demonstrated agricultural science”; Secretary Vilsack called it “a path very different from the one the U.S. is pursuing.” The F2F initiative aims to transition the EU to a sustainable food system such that it also achieves significant mitigation of climate change. But Mr. Vilsack chose to counter the F2F efforts by promoting an “alternative strategy” — under the moniker “Coalition for Productivity Growth” — through which “other nations pledge not to follow the European path on farm policy.” He has described this alternative, U.S.-led strategy as “a market-oriented, incentive-based, voluntary system [that] is effective” at slashing agricultural carbon emissions. Climate, pesticide, organics, and other environmental and health advocates, including Beyond Pesticides, are troubled by these actions. Mother Jones poses the central question in the headline of its September 30 article: Why is Secretary Vilsack So Afraid of a Plan to Cut […]

(Beyond Pesticides, October 6, 2021) Agricultural soils under monoculture cropping systems are not as healthy as soils with diverse plantings, finds research recently published in the journal Agrosystems, Geosciences and Environment. Soil and soil quality are declining rapidly in the United States and around the world, with recent data indicating that the U.S. Corn Belt has lost 35% of its topsoil. Advocates say it is critical that the response to this problem focus on practices that conserve and improve the soil health by building organic matter and healthy microbial populations. “Understanding the management practices that lead to healthier soils will allow farmers to grow the same crops while reducing costly chemical inputs (fertilizers, pesticides, herbicides) and protecting the environment,” said study coauthor Lori Phillips, PhD. To investigate disparities in soil health between cropping systems, researchers analyzed a long-term cropping system that includes 18 years of continuously grown soy, corn, and perennial grasses. Each cropping system was evaluated for its bacterial and fungal population, as well as a test called CNPS, which measures the enzymes produced by microbes specifically related to the soil’s carbon, nitrogen, phosphorous, and sulfur cycles. Researchers indicate that these measurements create “a holistic measure of biological activity,” […]

(Beyond Pesticides, October 4, 2021) Recent findings of high levels of toxic pesticides in products permitted to be used as “minimum risk pesticides” (terminology used for essentially nontoxic) point to the need for greater oversight of these products and more severe penalties for violations. Pesticides classified as minimum risk are allowed under Section 25(b) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) [40 CFR 152.25(f)] to be used without going through EPA’s pesticide registration process. These products are limited to a specific list of ingredients, and all ingredients, including “inert” ingredients, are required to be listed on the label.  Minimum risk pesticides are used by organic growers, municipalities, and others who are not permitted to use, or choose to avoid, toxic chemicals.  Tell EPA and Congress to protect the integrity of minimum risk pesticides. Organic growers can lose their organic certification if they apply materials that are prohibited, which include the toxic ingredients glyphosate, bifenthrin, permethrin, cypermethrin, and carbaryl, found by the state of California in dangerous and misbranded Eco-MIGHT and W.O.W. (Whack Out Weeds!) products, falsely labeled as 25(b) minimum risk. Contamination of these products came to light in late July, when the California Department of Food and […]

(Beyond Pesticides, September 30, 2021) Individuals working or living in areas with frequent neurotoxic pesticide use experience more amyotrophic lateral sclerosis (ALS) incidences than the general population. The study, published in NeuroToxicology, finds a positive association between sporadic (non-genetic, spontaneous) ALS incidences among individuals exposed to neurotoxic pesticides.  Amyotrophic lateral sclerosis (or Lou Gehrig’s disease) is a neurodegenerative disease that affects the nerves in the brain and spinal cord. As many as 16,000 – 20,000 Americans live with this condition, which weakens muscle/motor function leading to loss of muscle control for walking, talking, eating/swallowing, and breathing. Severe ALS progression is fatal and has no current cure. Although research supports genetic factors play a role in disease etiology (cause), most ALS cases do not result from genetic inheritance. Several research studies demonstrate exposure to environmental or work-related toxicants (i.e., pesticides) predispose humans to the disease. With researchers predicting a global ALS incidence increase of 69% by 2040, identifying ALS’s causal factors are important to future research. Therefore, research like this showcases the importance of assessing aggregate health risks associated with toxic chemical exposure, especially for illnesses, which are not curable. In this study, the researchers note, “[W]e identified pesticides applied to crops in the area of […]

(Beyond Pesticides, September 29, 2021) Bats foraging in chemical-intensive banana plantations have much less gut diversity than bats foraging in organic banana fields and natural forestland, finds research published this month in the journal Frontiers in Ecology and Evolution. Although there is increasing recognition that a diet of conventional, chemically grown food leads to adverse disruptions of the gut microbiome (also known as dysbiosis), little research has been conducted on the effect of production practices on the gut of wild foraging species. According to the present study there are significant differences that regulators must begin to account for in pesticide risk assessments, and consumers should consider when making choices at the supermarket. Researchers focused their investigation on Pallas’s long-tongued bat (Glossophaga soricina), a nectar feeding bat native to Central and South America. The bat is highly adapted to human environments, sustaining populations in both conventional and organic banana plantations, as well as surrounding forest land. For the study, researchers trapped nearly 200 bats across the country of Costa Rica over a 22-month time span. After trapping, physiological characteristics, like size and body weight, were measured, and bat guano was analyzed for its microbial population. All sampled bats were released back […]
