One group of bees was fed a sterile sugar syrup, while others were exposed to levels of glyphosate equal to what is found in conventional crop fields, lawns and highway medians. To aid tracking and recapture, bees were marked with colored dots based on their grouping. Researchers sampled 15 individuals from each group of worker bees right before and three days after reintroduction back to the hive. At both times, DNA from the insects\u2019 guts was extracted to observe whether glyphosate had significantly altered microbial diversity within their organ system.<\/p>\n<p>Results found relatively minimal impacts to bees tested prior to their reintroduction to the hive. However, bees tested three days after returning to their hive revealed significant changes in their gut make-up, trending towards lower levels of important beneficial gut bacteria when compared to unexposed bees. Of eight key species of beneficial bacteria in the exposed honey bees\u2019 microbiome, four were found to be less abundant.\u00a0 In fact, the bacteria species most directly affected, <em>Snodgrassella alvi,<\/em> is crucial for aiding the bees\u2019 ability to both process food and defend against harmful pathogens.<\/p>\n<p>Erick Motta, the graduate student who led the research, said: \u201cWe need better guidelines for glyphosate use, especially regarding bee exposure,\u201d noting that EPA regulation guidelines \u201cassume bees are not harmed by the herbicide,\u201d though this study, like others, shows such an assumption of safety to be wildly ill-informed.<\/p>\n<p>Indeed, such diverse bacteria are what keep immune systems resilient against illness and other types of stresses.\u00a0 Regardless of their role in maintaining a functioning immune system, the chemical industry has trolled homeowners to both distrust and work swiftly to exterminate <em>all<\/em> bacteria with a panoply of toxic products.<\/p>\n<p>As a result of glyphosate exposure, honey bees with weakened gut microbiomes were later more likely to die after coming in contact with the widespread pathogen, Serratia marcescens.\u00a0 Noting the pathogen\u2019s detrimental effect on honey bees, about half of unexposed honey bees with healthy immune systems were able stave off infection and stay alive eight days after contracting the pathogen.\u00a0 Comparatively, only one tenth of the bees exposed to glyphosate were still alive eight days after contracting the pathogen.\u00a0 Without a resilient immune system propped up by a healthy microbiome, the study finds further evidence that living organisms find it increasingly difficult to maintain health amidst our toxic-plagued urban environments and conventional agriculture.<\/p>\n<p>Such a negative impact on gut microbiome is devastating for pollinators already assailed by immune-system-compromising chemicals, scarcity of diverse forage, and environmental pressures on habitat. Glyphosate, for all who are not familiar, is one of the world\u2019s most widely and indiscriminately sprayed pesticides.\u00a0 Its annual use in the U.S. has soared from 40 million pounds in the mid-1990s to around 300 million pounds used annually today.\u00a0 And unsurprisingly, resistance to the pesticide continues to increase in target species due such excessive use.<\/p>\n<p>This isn\u2019t the first study to find adverse impacts from pollinator exposure to glyphosate. In 2015, a study linked glyphosate exposure to <a href=\"https:\/\/beyondpesticides.org\/dailynewsblog\/2015\/09\/sublethal-glyphosate-roundup-exposure-harms-bees\/\">impaired learning in honey bees<\/a>, with evidence that field realistic doses of the chemical cause delays in the return of foraging honey bees to the hive.<\/p>\n<p>And the effect of glyphosate on gut diversity is not limited to pollinators, according to recent research. Beyond Pesticides summer 2017 <em>Pesticides and You <\/em>article, Monsanto\u2019s Roundup (Glyphosate) Exposed explores how this herbicide may also be weakening human immune systems by disrupting our gut microbiome.<\/p>\n<p>As co-author of the study, Professor Nancy Moran, Ph.D., stated to <em>Sustainable Pulse<\/em>: \u201cStudies in humans, bees and other animals have shown that the gut microbiome is a stable community that resists infection by opportunistic invaders.

The founders, who established Beyond Pesticides (originally as National Coalition Against the Misuse of Pesticides) as a nonprofit membership organization in 1981, felt that without the existence of such an organized, national network, local, state and national pesticide policy would become, under chemical industry pressure, increasingly unresponsive to public health and environmental concerns. Beyond Pesticides believes that people must have a voice in decisions that affect them directly. We believe decisions should not be made for us by chemical companies or by decision-makers who either do not have all of the facts or refuse to consider them. Learn more about our work, read A Year in Review\u20142021, our accomplishments are your victories! Beyond Pesticides seeks to protect healthy air, water, land, and food for ourselves and future generations. By forging ties with governments, nonprofits, and people who rely on these natural resources, we reduce the need for unnecessary pesticide use and protect public health and the environment. Beyond Pesticides provides hands-on services to the public and supports local action by: identifying and interpreting hazards; and, designing safe pest management programs. With the information provided by Beyond Pesticides, people may not only be able to make informed choices and adopt practices that protect themselves and their families from unnecessary exposure to pesticides, but they will be able to effect changes on community-wide pest management decisions and policies that govern pesticide use, such as pesticide uses in parks, schools, for community insect control and along roadsides.

The founders, who established Beyond Pesticides (originally as National Coalition Against the Misuse of Pesticides) as a nonprofit membership organization in 1981, felt that without the existence of such an organized, national network, local, state and national pesticide policy would become, under chemical industry pressure, increasingly unresponsive to public health and environmental concerns. Beyond Pesticides believes that people must have a voice in decisions that affect them directly. We believe decisions should not be made for us by chemical companies or by decision-makers who either do not have all of the facts or refuse to consider them. Learn more about our work, read A Year in Review\u20142021, our accomplishments are your victories! Beyond Pesticides seeks to protect healthy air, water, land, and food for ourselves and future generations. By forging ties with governments, nonprofits, and people who rely on these natural resources, we reduce the need for unnecessary pesticide use and protect public health and the environment. Beyond Pesticides provides hands-on services to the public and supports local action by: identifying and interpreting hazards; and, designing safe pest management programs. With the information provided by Beyond Pesticides, people may not only be able to make informed choices and adopt practices that protect themselves and their families from unnecessary exposure to pesticides, but they will be able to effect changes on community-wide pest management decisions and policies that govern pesticide use, such as pesticide uses in parks, schools, for community insect control and along roadsides. Beyond Pesticides believes that people must have a voice in decisions which affect them directly.","sameAs":["https:\/\/www.beyondpesticides.org","https:\/\/www.facebook.com\/beyondpesticides\/","https:\/\/www.instagram.com\/beyondpesticides\/","https:\/\/www.linkedin.com\/company\/beyond-pesticides\/","https:\/\/x.com\/ByondPesticides","https:\/\/www.youtube.com\/user\/bpncamp\/"],"url":"https:\/\/beyondpesticides.org\/dailynewsblog\/author\/beyond-pesticides\/"}]}},"_links":{"self":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/23489","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/comments?post=23489"}],"version-history":[{"count":5,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/23489\/revisions"}],"predecessor-version":[{"id":23500,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/posts\/23489\/revisions\/23500"}],"wp:attachment":[{"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/media?parent=23489"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/categories?post=23489"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/beyondpesticides.org\/dailynewsblog\/wp-json\/wp\/v2\/tags?post=23489"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
