A new report shows a number of popular breakfast foods could possibly contain dangerous amounts of glyphosate, the main ingredient found in weed killer.

Last week, a jury awarded a former school groundskeeper $289 million after he sued the company, Monsanto, claiming their weed killer, which contains glyphosate, was the cause of his terminal cancer.

The environmental workgroup tested foods including granola, snack bars, cereal, instant oats and whole oats. Out of the 29 oat-based foods that were tested, only five did not test positive for glyphosate.
