(Beyond Pesticides, January 30, 2023) Because antibiotics and fungicides are widely used in agriculture (except organic), they contribute significantly to the increasing efficacy problems with antimicrobial (antibiotic and antifungal medicines) use in health care, contributing to a growing crisis. According to Tedros Adhanom Ghebreyesus, PhD, World Health Organization Director-General, “Antimicrobial resistance undermines modern medicine and puts millions of lives at risk.”  Microorganisms—including bacteria, fungi, and viruses—are notoriously quick to evolve resistance to antimicrobial medicines. We know that selection for resistance is directly related to the frequency and intensity of antimicrobial use, so medical practitioners try to avoid using those medicines unless they are necessary. Tell EPA to cancel all uses of a pesticide when resistance is discovered or predicted to occur. Tell Congress to ensure that EPA protects public health from deadly antifungal and antibiotic resistance. Unfortunately, the medical profession lacks complete control over the use of antimicrobials. Many of the same chemicals used in human medicine are also used in agriculture. These may show up in or on treated food, but can also spread antimicrobial resistance through horizontal gene transfer. So, in addition to ingesting antibiotics in our food, the movement of resistant bacteria and fungi in the environment […]

(Beyond Pesticides, February 28, 2022) When bacteria and fungi become resistant to pesticides, it is a signal that the toxic chemical approach to controlling pathogens does not work. But resistance also poses a direct threat to human health when the pesticide (or a related chemical) is used in human medicine. Tell EPA to cancel all uses of a pesticide when resistance is discovered or predicted to occur. Tell Congress to ensure that EPA protects public health from deadly antifungal and antibiotic resistance. The threat of resistance in bacterial human pathogens has long been widely recognized. Although research sponsored by the Environmental Protection Agency (EPA) recognizes the spread of resistance to antibiotics important in human medicine through horizontal gene transfer in the environment, EPA inaction both on antibiotic and antifungal resistance has become a growing crisis. EPA does recognize the existence of resistance to fungicides. It uses codes produced by the Fungicide Resistance Action Committee in decisions regarding fungicide registration. Although EPA says resistance “may be considered in the risk-benefit decision-making process,” there is no evidence that the agency actually considers the failure of EPA-registered pesticides to control the target organisms in registering pesticides. That failure has a serious impact on […]

(Beyond Pesticides, January 25, 2022) Research at the University of North Carolina at Chapel Hill identifies how triclosan (TCS), an antimicrobial agent used in many household products, impacts the microbial communities in the gut, causing inflammation. According to the study published in Nature Communications, triclosan worsens the effects of ulcerative colitis, an inflammatory bowel disease (IBD), through the retention of harmful bacteria. Ample evidence demonstrates environmental contaminants, including pesticides like triclosan, negatively affect microbes in the human mouth and gut. Although studies show how triclosan exposure affects human health, more research is now questioning how exposure to these toxic chemical influences gut health. Therefore, studies like these highlight the importance of evaluating how chemical contaminant deregulates normal bodily function through microbiome changes. Furthermore, the study has significant implications for considerations that should be, but are not currently, a part of pesticide review and registration by the U.S. Environmental Protection Agency (EPA). The researchers note, “Together, our results define a mechanism by which intestinal microbes contribute to the metabolic activation and gut toxicity of TCS, and highlight the importance of considering the contributions of the gut microbiota in evaluating the toxic potential of environmental chemicals.” Instances of intestinal bowel disease (IBD)—involving the chronic inflammation […]

(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, May 3, 2021) Hazardous disinfectants are not necessary for protection against COVID-19, and the Centers for Disease Control and Prevention (CDC) is agreeing. The U.S. Environmental Protection Agency (EPA) seems to now agree, but has not changed it recommendations and listing for the public. Since last March, EPA has recommended disinfectants on List N for protecting against exposure to surfaces that would spread the virus causing COVID-19. Beyond Pesticides has evaluated the disinfectants, categorizing them as materials to seek out or to avoid. More recently, we evaluated the available evidence and recommended that schools and other institutions concentrate on providing adequate ventilation and protection from airborne virus. Tell EPA to remove risky disinfectants from its recommended list. EPA’s List N contains products containing toxic chemicals such as chlorine bleach, peroxyacetic acid, alkyl dimethyl benzyl ammonium chlorides, didecyl dimethyl ammonium chloride, and other “quats,” sodium dichloro-s-triazinetrione, and hydrochloric acid. In addition to their outright toxicity, some of these can also trigger asthma attacks. Now, EPA has recognized this evidence and offered revised recommendations, stressing the need to avoid airborne transmission and stating in an infographic that the risk of contracting disease by touching contaminated surfaces is low and that disinfectants […]

(Beyond Pesticides, April 29, 2021) Glyphosate-based herbicides (GBHs) are incompatible with sustainable agriculture goals, according to a recent scientific literature analysis by scientists at Tufts University, Massachusetts. Glyphosate is the most commonly used pesticide active ingredient worldwide, appearing in many herbicide formulas, including Bayer’s (formerly Monsanto) RoundupTM. The use of this chemical has been increasing since the inception of crops genetically modified to tolerate glyphosate. However, studies demonstrate glyphosate is the main contributor to human, biotic, and ecosystem harms as toxicities from herbicides are now double what it was in 2004.  The National Academy of Sciences identifies four goals of sustainable agriculture—productivity, economics, environment, and social well-being for future generations. However, pesticides like glyphosate are ubiquitous in the environment, putting the health, economy, and food/resources for future generations at risk. Therefore, research like this is vital for understanding how chemical use can undermine sustainable agriculture goals to protect humans, animals, and environmental health. Researchers note, “[W]hether or not GBHs are viewed as essential or unessential to contemporary agriculture, and notwithstanding their role in non-tillage agriculture, this study shows that glyphosate-based herbicides do not reach the bar of agricultural sustainability, with respect to humans and the environment, making the system they are part of unsustainable.” Researchers thoroughly examined […]

(Beyond Pesticides, November 9, 2020) Now that we have learned what a pandemic looks and feels like, with the astounding levels of infection, hospitalization, and death from COVID-19, we must take serious steps to prevent another pandemic on the horizon—this one tied to bacterial resistance to antibiotics. An important article in The Lancet points to a “looming potential pandemic” resulting from a “rise in multidrug-resistant bacterial infections that are undetected, underdiagnosed, and increasingly untreatable, [which] threatens the health of people in the USA and globally.” Tell your Congressional Representative and Senators it is urgent that the National Action Plan for Combating Antibiotic-Resistant Bacteria be initiated. Two contributors to antimicrobial resistance (AMR) that are being highlighted are in agriculture and use of antibiotics in medicine when not warranted. The misuse of antibiotics in agriculture includes antibiotics used to control certain bacterial diseases in plant agriculture (especially oxytetracycline and streptomycin). While crop uses are important contributors to breeding bacterial resistance, they are small compared to their uses in livestock production. Antibiotics are used largely as additives to animal feed to ward off any potential infections and to promote unnaturally rapid growth (the latter of which translates to higher profits), rather than being used […]

(Beyond Pesticides, August 10, 2020) As parents, educators, and administrators decide whether to open schools with in-person teaching, there are escalating concerns about the ability of schools to put in place the programs necessary to protect the health of students, staff, and their families from coronavirus (COVID-19). A key part of most school reopening plans is the fogging or misting of classrooms with toxic disinfectants, raising questions about safe and effective disinfection and sanitizing practices, in addition to social practices that public health officials have advised, to prevent transmission of the virus. For those who want to advocate for protective measures prior to school reopening: Tell Congress and Governors that schools must reopen only when safe. Schools must have adequate resources to ensure safety. “While people are eager to reopen schools, it is critical that they adopt basic cleaning and safe and effective disinfection procedures, ventilation and infrastructure changes, and adequate maintenance support,” said Jay Feldman, executive director of Beyond Pesticides. “However, these basic practices must follow the recommendations of public health officials, including a less than one percent community transmission rate, social distancing and masks, adequate disease detection testing, contact tracing, and quarantining procedures,” he said. In spite of […]

(Beyond Pesticides, August 10, 2020) Despite pressure to reopen schools, concerns persist about the threat to the health of children, teachers, school staff, and families. There are many complex social, scientific, and logistical issues involved in a decision to reopen schools for in-person teaching.  >>Tell Congress and Governors that schools must reopen only when safe. Schools must have adequate resources to ensure safety. Beyond Pesticides joins the National Education Association (NEA), American Federation of Teachers (AFT), National Parent and Teacher Association (PTA), and others in calling for a well-thought-out approach to reopening schools only when it is shown that: The pandemic is under control in the community—as evidenced, for example, by an average daily community infection rate among those tested for COVID-19 below 5% and a transmission rate below 1%. Protections have been put in place to keep the virus under control and protect students and staff. These include accommodations for students and staff at high risk; measures and building retrofits to protect against all forms of transmission; procedures for detecting disease, quarantining, and notification; involvement of families and educators in decisions; monitoring; and enforcement. Plans are in place that ensure continuous learning equitably for all students, with training for educators, […]

(Beyond Pesticides, June 3, 2020) While wearing a mask is an important practice to help reduce the chance of Covid-19 infection, a mask produced with pesticide-laden material for Tennessee residents has been identified as elevating the virus’ health risks. The state of Tennessee began last week and then stopped this week providing residents with free face masks made from sock fabric incorporated with antimicrobial silver pesticide. The investigative unit of NewsChannel 5 Nashville uncovered that the masks contain a toxic antimicrobial pesticide. Because of the U.S. Environmental Protection Agency’s (EPA) interpretation of federal pesticide law, textiles and other materials, typically plastics, infused with toxic antimicrobial substances are not evaluated by the agency for the wide range of exposure patterns associated with the use of these toxic products. In addition, the silver product in the sock material, Silvadur 930 Flex, states on its label that over 99% of product ingredients are “other ingredients” and provides no disclosure on their potential hazards. Beyond Pesticides’ board member Warren Porter, PhD, environmental toxicology professor at University of Wisconsin at Madison, in an interview with NewsChannel 5, assessed the situation bluntly. Dr. Porter told reporters over a Zoom interview, “I wouldn’t wear one,” after explaining […]

(Beyond Pesticides, April 24, 2020) The Centers for Disease Control and Prevent (CDC) has released a study showing a sharp increase—62% in some cases—in calls to poison hotlines about exposures to toxic household cleaners and disinfectants. This poisoning comes with the advent of the novel Coronavirus pandemic, as public health and government officials, and many media outlets have sensibly recommended that people regularly disinfect “high touch” surfaces and objects in their homes and other surroundings, but have not issued warnings on toxic effects nor the availability of lower toxicity or least-toxic products. Compliance with cleaning (sanitizers) and disinfection recommendations is an important public and personal health undertaking, but in this Covid-19 rigor lies a poison problem: the toxicity, as Beyond Pesticides has explained, of some cleaning and disinfecting products that are permitted by the Environmental Protection Agency (EPA) for sale and use. There are safer ways to disinfect those light switches, TV remotes, doorknobs, faucets, etc. First, a basic distinction between cleaning (also called sanitizing)and disinfecting: EPA offers definitions of the differences. “Cleaning is done with water, a cleaning product, and scrubbing. Cleaning does not kill bacteria, viruses, or fungi, which are generally referred to as ‘germs.’ Cleaning products are used […]

(Beyond Pesticides, March 27, 2020) Faced with the COVID-19 (coronavirus) threat, there is tremendous pressure to use toxic disinfectants, despite the availability of safer products. In fact, while the Centers for Disease Control and Prevention (CDC) is recommending 70% alcohol for surface disinfection, the U.S. Environmental Protection Agency’s (EPA) Office of Pesticide Programs is advising the use of unnecessarily toxic substances, and reducing standards that govern their allowance on the market. EPA’s pesticide program allowed 70 new disinfectants yesterday, at the same time that the agency overall announced that it is waiving enforcement of environmental standards during the coronavirus outbreak—a devastating blow to public health and environmental protection. Beyond Pesticides, in its factsheet, Protecting Yourself from COVID-19 (coronavirus) without Toxic Sanitizers and Disinfectants, says, “Fight the coronavirus with common sense prevention and safer disinfection products. Avoid products that increase vulnerability to respiratory problems.” (See the factsheet below.) To some extent, the expanded allowance of disinfection products on top of the 281 disinfectants previously permitted has been made possible by relaxing oversight on so-called “inert” or other ingredients that are not disclosed on product labels and often highly toxic. The agency says it is allowing the use of these “inerts” with “no […]
