"USDA Organic" be definition means the item isn't genetically modified; also oftentimes you can see "non-GMO soy" or "not genetically engineered" on the packaging. Also things like "no growth hormones" "Rbgh-free" and the like.
But it's important to read the labeling/ingredient panel and not be taken in by pretty pictures and "quick-glance" nutrition figures or phrases like "high-fiber" printed in the front of the package, where people immediately first look and don't look anywhere else.
