Monsanto Is Scrambling To Bury This Breaking Story – Don’t Let This Go Unshared!
A FDA-registered food safety laboratory tested iconic American food for residues of the weed killer glyphosate (aka Monsanto’s Roundup) and found ALARMING amounts.
Just to give you an idea of how outrageous these amounts are, independent research shows that probable harm to human health begins at really low levels of exposure – at only 0.1 ppb of glyphosate. Many foods were found to have over 1,000 times this amount! Well above what regulators throughout the world consider “safe”.
