A pilot study of American mothers’ milk has found levels of the herbicide glyphosate around 1,000 times higher than allowed in European drinking water. Campaigners are demanding a ban on the use of glyphosate on food crops. In the first ever testing on glyphosate herbicide in the breast milk of American women, Moms Across America and Sustainable Pulse have found ‘high’ levels in three out of the ten samples tested.
