In 2016, a lawsuit was filed against Quaker Oats in the Federal district courts of both New York and California after trace amounts of glyphosate were found in oatmeal. The lawsuit alleged that the claim of "100% natural" was false advertising. That same year General Mills dropped the label "Made with 100% Natural Whole Grain Oats" from their Nature Valley granola bars after a lawsuit was filed that claimed the oats contained trace amounts of glyphosate.
