Whoo boy . . . a new round of tests by the Environmental Working Group found the weedkiller glyphosate, more commonly known as Roundup, in every single breakfast cereal sample tests. That’s 28 different cereals!

From the EWG:

The tests detected glyphosate in all 28 samples of products made with conventionally grown oats. All but two of the 28 samples had levels of glyphosate above EWG’s health benchmark of 160 parts per billion, or ppb.

Products tested by Anresco Laboratories in San Francisco included 10 samples of different types of General Mills’ Cheerios and 18 samples of different Quaker brand products from PepsiCo, including instant oatmeal, breakfast cereal and snack bars. The highest level of glyphosate found by the lab was 2,837 ppb in Quaker Oatmeal Squares breakfast cereal, nearly 18 times higher than EWG’s children’s health benchmark.
