(Beyond Pesticides, January 2, 2019) The “indoor microbiome†of yoga studios and other athletic facilities often contain significant levels of antibacterial chemicals like triclosan, which show up in dust and breed antibiotic resistance, according to research published last month in the journal mSystems. Triclosan may be banned from hand soaps, but its continued use in a myriad of other products, from disinfectant sprays to impregnated clothing, yoga mats, and other work-out equipment makes it difficult to avoid this now-ubiquitous chemical. This is a public health concern because these antibacterial or antimicrobial chemicals are link to antibiotic-resistant bacteria. Antibiotic resistance kills over 23,000 people each year, according to the Centers for Disease Control and Prevention (CDC). In addition to the CDC, the World Health Organization has cited this escalating problem as become one of the biggest public health challenges of our time. Many people may suspect their gym or yoga study is not a germ-free location, but attempts to address these germs through antibacterial sprays or impregnated yoga mats and other surfaces, may be exacerbating the issue—doing much more harm than good. The continued detection of triclosan and its impacts at new and unexpected locations are feeding renewed calls for a complete ban on […]

(Beyond Pesticides, November 16, 2018) Pesticides and biocides used to control bacterial infections in humans and weeds and pests in agriculture are surpassing ‘planetary boundaries’ within which human civilization can continue to rely on these biocides, according to a review by an international team of scientists working on the Living with Resistance project. While the study reinforces the role of susceptible populations in managing resistance, it fails to distinguish essential differences between antibiotic resistance and resistance to pesticides that is identified by Beyond Pesticides. The study focuses on six different forms of resistance. Researchers looked at antibiotic resistance in gram negative bacteria (such as E. coli, P. aeruginosa, Salmonella) and gram positive bacteria (such as S. aureus, Clostridium) separately, due to their divergent resistance mechanisms. Pesticide resistance was divided among herbicides in general, herbicide resistant crops, insecticides in general, and genetically engineered (GE) crops that produce their own insecticide. Resistance to antibiotics and pesticides are similar in that they are both evolved responses to substances toxic to the organism. However, lumping them together in evaluating their importance to human health and survival does not recognize important differences in context. “Without new approaches, going to hospital in the future will increasingly become […]

(Beyond Pesticides, September 17, 2018) The Fall 2018 NOSB meeting dates have been announced and public comments are due by October 4, 2018. Your comments and participation are critical to the integrity of the organic label. Written comments may be submitted through Regulations.gov until 11:59 pm ET October 4, 2018. Reservations for in-person and webinar comments close at the same time. The proposals of the National Organic Standards Board (NOSB), as a part of its ongoing review of practices and materials, are published for public comment. On our Keeping Organic Strong page, Beyond Pesticides will be providing the public with a listing and analysis of the issues under consideration of the Board when it meets in Saint Paul, MN on October 24 – 26, 2018. You can view USDA’s announcement of the NOSB’s meeting and proposals here. Issues before the NOSB include materials allowed in organic production as well as some policy issues. Materials are either the subject of petitions or the subject of sunset review (concerning whether to be allowed for another 5 years). To be allowed, materials must have evidence summarized in the proposals that they meet the OFPA requirements of essentiality, no adverse effects on humans and the […]

(Beyond Pesticides, November 21, 2017) Both the active and inert ingredients in common herbicides induce antibiotic resistance in human pathogenic bacteria, according to the latest research from New Zealand scientists, published in Microbiology this week.  Previous research from the same team found in 2015 that commercial formulations of Roundup (containing glyphosate and inert ingredients) and Kamba (containing 2,4-D, Dicamba, and inert ingredients) caused antibiotic resistance to develop in Salmonella eterica and Escherichia coli, but this new research drills down into what ingredients in these formulations resulted in the effect. Lead author of the study, Jack Heinemann, PhD, University Canterbury’s School of Biological Sciences, explains that ultimately this research indicates that, “The sub-lethal effects of industrially manufactured chemical products should be considered by regulators when deciding whether the products are safe for their intended use,†Scientists parsed out the effects of individual active and inert ingredients by obtaining pure, technical grade dicamba, 2,4-D, and glyphosate, as well as the inert co-formulants “Tween80†and “CMC,†which are respectively, used to reduce surface tension and regulate the viscosity in a formulated herbicide, though also used as emulsifiers in foods like ice cream and in medicines. The technical grade herbicides were first applied to […]

(Beyond Pesticides, July 12, 2017) In a move that threatens to further the spread of antibiotic resistance, researchers at the University of Western Australia (UWA) mining a collection of antimalarial drugs for potential new herbicides. Joshua Mylne, PhD, a senior lecturer in the School of Molecular Sciences (SMS) who directs the project, got started based on work he did while in the Australian Army Reserve. There he discovered that “malarial parasites are actually closely related to plants.†Due to widespread resistance of weeds to the popular herbicide glyphosate, Dr. Mylne began investigating antimalarial drugs as potential replacements. Malaria parasites are actually protozoans in the genus Plasmodium. Their crucial connection with plants is that the parasite contains a plastid similar to the chloroplast in plants. Like the chloroplast in plants, this plastid is critical for the survival of the parasite. Along with organic chemist Keith Stubbs, PhD, associate professor in SMS, Dr. Mylne began screening chemicals in the “Malaria Box,†an open source collection of potential anti-malarial drugs that have never been commercialized. Of the 20 chemicals tested on the small weed Arabidopsis thaliana, 11 were found to have some herbicidal activity. They were then compared to the herbicides glyphosate, glufosinate, asulam, […]
