5 clean oat cereals ranked by lowest ppb

Oat-based cereals consistently rank among the highest glyphosate-contaminated foods tested. Because oats are commonly sprayed with glyphosate as a pre-harvest desiccant to speed drying, residue concentrates in finished products like rings, squares, and crisps. Multiple EWG studies found contamination in virtually every oat cereal tested — with some brands exceeding the child-safe benchmark by more than 15×. The picks below are the cleanest oat cereal we found, ranked by glyphosate level (lowest first). Each has been lab-tested by an independent third party.
