Glyphosate study shows adverse health effects at "safe" dose  (GM Watch, 16 May 2018) 'The study was focused on the newborn, infancy and adolescence phases of life. The results reveal that glyphosate-based herbicide (GBH) was able to alter certain important biological parameters, mainly relating to sexual development, genotoxicity, and the intestinal microbiome....The effects occurred at a dose deemed safe by regulators to ingest on a daily basis over a long-term period. In human-equivalent terms the dosing period corresponded to the period from the embryo stage to 18 years of age.' The levels measured in urine suggest 'a bioaccumulation effect of glyphosate that was proportional to the length of treatment.'      more on glyphosate at fact sheets/ glyphosate

Study finds link between pesticide exposure and microbiome changes (UPI, By Brooks Hays. Nov. 11, 2016)  The oral microbiome of farmworkers are markedly different than other humans, and pesticide exposure explains why, new research shows. Adults with concentrations of organophosphate pesticide, Azinphos-methyl, in their blood had a significantly altered oral microbiome. "We found significantly reduced abundances of seven common taxa of oral bacteria, including Streptococcus, one of the most common normal microbiota in the mouth," researcher Ian B. Stanaway said in a news release. Researchers also found a correlation between pesticide exposure and shifts in the abundance and diversity of several other strains and species of bacteria, including microbes belonging to genera Streptococcus and HalomonasAdditionally, scientists measured shifts in bacterial diversity related to changing levels of exposure during the seasons. "The challenge becomes, what does this mean," said researcher Elaine M. Faustman. "We don’t know, but we depend on the micriobiome for many metabolic processes." link to studySNAP Comment: This is the first study I know of that has looked at this issue. Although it specifically studies the organophosphate Azinphos-methyl, I would not be surprised that the link also exists with other pesticides. Time will tell. According to PMRA label search (15 Nov 2016), Azinphos-methyl is no longer sold in Canada. I did not check every historical label but the last sale I could find was in 2010. It could still be used by those with a stockpile.
