(CNN) Arman Azad, December 24, 2018 — Dozens of common breakfast cereals and snack bars have trace amounts of a controversial herbicide found in the weed killer Roundup, according to a report released today by an environmental advocacy group.
The Environmental Working Group (EWG) found that 26 of the 28 products it tested had levels of Roundup’s main ingredient, glyphosate, that were “higher than what EWG scientists consider protective of children’s health.” An earlier report found similar results in over thirty oat-based foods.
Manufacturers say their products are safe, but the EWG report argues that the vast majority of foods tested — such as Honey Nut Cheerios and Quaker Simply Granola Oats — have glyphosate levels that might pose a cancer risk with long-term consumption.
None of the foods violated EPA limits on the herbicide, but the EWG uses a far more conservative health benchmark. California’s proposed glyphosate limit, which would be the most restrictive in the country, still allows for glyphosate levels that are over a hundred times higher than the EWG’s threshold.
