evidence: With major food and grain companies cracking down on farmers spraying glyphosate on crops such as wheat, oats, and edible beans prior to harvest, the controversial practice may be phased out completely. In July, Richardson International, Canada’s largest agribusiness, announced that starting next year it would no longer buy oats that had been sprayed with glyphosate, the main ingredient in Roundup herbicide, before harvest. [...] Today there are residues as consumer advocacy groups have conducted several studies finding high levels of glyphosate in wheat, oat, and bean products. The Environmental Working Group has conducted several studies finding high levels of glyphosate in oat food products like granola, oatmeal, and snack bars. In one study, glyphosate was found in every sample of oat-based cereals and snack products. All but four of the 21 products contained levels of glyphosate higher than what EWG scientists consider protective for children’s health with an adequate margin of safety. More recently EWG commissioned laboratory tests that found glyphosate in more than 80% of non-organic hummus and chickpeas samples. Glyphosate is also used as a drying agent on chickpeas.
