Glyphosate shown to disrupt microbiome 'at safe levels', study claims

Study on rats said to show that the chemical, found in Monsanto's Roundup weedkiller, poses 'a significant public health concern'

A chemical found in the world's most widely used weedkiller can have disrupting effects on sexual development, genes and beneficial gut bacteria at doses considered safe, according to a wide-ranging pilot study in rats.

Glyphosate is the core ingredient in Monsanto's Roundup herbicide and levels found in the human bloodstream have spiked by more than a 1,000% in the last two decades.
