In testing done by Friends of the Earth (FOE), 100 percent of oat cereal samples tested positive for residues of glyphosate, the active ingredient in Roundup herbicide. While there are multiple reasons to reconsider the health value of oats, including their lectin content, the rampant use of glyphosate on this crop as a desiccant just prior to harvest, and their subsequent glyphosate contamination, is worthy of attention.
FOE, looking to uncover how many pesticides and herbicides residues are in commonly eaten foods, tested store-brand cereal, beans and produce from the top four food retailers in the U.S.: Walmart, Kroger, Costco and Albertsons/Safeway.
Altogether, 132 samples of house brand samples were tested, from more than 30 U.S. stores in 15 states. Residues of glyphosate and pesticides — neonicotinoids and organophosphates — were found, with glyphosate being detected in 100 percent of oat cereal and pinto bean samples tested.
The average level of glyphosate in cereal samples was 360 parts per billion (ppb), which FOE noted is more than twice the level set by Environmental Working Group (EWG) scientists for lifetime cancer risk in children. Some of the cereal samples contained residues as high as 931 ppb.
As for pinto beans, levels were found up to 1,128 ppb, although average glyphosate levels were 509 ppb — 4.5 times higher than EWG’s benchmark for lifetime cancer risk in children. According to FOE:
“EWG determined that a 1-in-a-million cancer risk would be posed by ingestion of 0.01 milligrams of glyphosate per day. To reach this maximum dose, one would have to eat a single 60-gram serving of oat cereal with a glyphosate level of 160 ppb or a 90-gram serving of pinto beans with a glyphosate level of 110 ppb.”
