Not to cause people to worry, but...
The USDA investigates hundreds of claims of fraudulently labeled organic foods every year. And if it doesn't have the USDA 'certified organic' seal on it, but just a 'shelf talker' or other unofficial label, is it really organic?
It is apparently legal to say "We use organic ingredients" on a label, but that doesn't mean every ingredient is organic or that the food meets the USDA certified organic standard.
