Tests found more of the toxic pesticide, glyphosate, first produced by Monsanto as Roundup, than some vitamins in samples of oat-based breakfast cereals marketed to children, an Environmental Working Group analysis shows. General Mills’ Honey Nut Cheerios and Quaker Oatmeal Squares, were tested. In 2017, glyphosate was also listed by the California Office of Environmental Health Hazard Assessment as a chemical known to the state to cause cancer. “If General Mills and Quaker refuse to remove glyphosate from these children’s cereals, then the companies should at least let parents know how much of this toxic weed killer they may be feeding their kids,” said EWG President Ken Cook.
