According to what I read in that story, USDA organic label means non GMO, also no chmical fertilizers or pesticides, and for meats, no hormones or antibiotics. I had not known previously that the USDA organic label meant that much.
But the comments about specific foods left me a little uncertain, since many of them said the thick skin protected the food from pesticides. What about the systemic ones that are sprayed on the plant or added to the irrigation water, so that the enire plant absorbs them?
....I hear strawberries are some of the most-sprayed, also grapes and apples, so better to get those organic. Stone fruits in general, also, I think.
I love it that someone is going to the trouble to research this and publish lists like this to help us out. Thanks, Bob!
