I find produce to be one of the hardest things to get organic in my area. With a family my size, cost is a factor, though I do my best. I did find this neat guide today which tells what non organic foods are not toxic to your health. I thought it might be helpful to others: http://www.thedailygreen.com/healthy-eating/eat-safe/Save-on-Sustainable-Gallery-44032808 at this site you can also see the worst foods as well. But here is a little handy shoppers take along: http://www.foodnews.org/sneak/EWG-shoppers-guide.pdf
Also please check the safe foods list as there are some who made that list that are not on the EWG safe shopping side. And the Daily green gives how to's on picking, which I found helpful.
Hope this is of help to others!
