Do Cheerios Have Pesticides?

Quick Answer: Yes, multiple tests have detected glyphosate (the active ingredient in Roundup) in Cheerios and other oat-based cereals. A 2018 EWG study found glyphosate in all 45 oat-based products tested, with Cheerios and Quaker Oats showing some of the highest levels.

Glyphosate, the world's most widely used herbicide, has been detected in numerous oat-based products. The Environmental Working Group (EWG) tested oat-based foods and found glyphosate in every single sample, with some exceeding EWG's health benchmark of 160 ppb. Cheerios averaged 470 ppb and Quaker Oats Old Fashioned averaged 1,000 ppb in some tests. Glyphosate is commonly sprayed on oat crops as a pre-harvest desiccant (drying agent), which is why oat products show particularly high residues. In 2015, the IARC classified glyphosate as "probably carcinogenic to humans" (Group 2A), though the EPA maintains it is not likely carcinogenic. General Mills (the maker of Cheerios) stated their products meet all regulatory requirements. Organic oat products have significantly lower or undetectable glyphosate levels.

Is glyphosate dangerous?

The IARC classifies glyphosate as 'probably carcinogenic.' Multiple lawsuits have resulted in billions in damages for cancer claims. The EPA and other agencies disagree on the risk level.
