(ABC 6 News) – A first of it’s kind study has discovered a pesticide in some common breakfast foods.

The chemical is called “chlormequat,” with experts saying large amounts of exposure will make you sick.

The non-profit group Environmental Working Group found chlormequat in 90% of studied foods, including Quaker Oats and Cheerios.

While the knee-jerk reaction may be to go out and buy organic, experts say that isn’t necessary.

“I don’t want people out there to think that organic necessarily always means healthier and they have to do that or they’re doing a disservice to their family,” said Dr. Alok Patel, an ABC News medical contributor. “You can still find nutritious foods that are not organic.”

In response to the study, Minnesota-based General Mills, caught with chlormequat in its products, insist its good meet all regulatory requirements.

But the group who conducted the study is asking the government to mandate more testing.
