The EWG (Environmental Working Group) has been working for years to gather facts and distribute the truth about toxins in our environment and the effect upon our health. You can trust these folks and their writings!

Every spring EWG releases their Shopper’s Guide to Pesticides in Produce™. The guide can be used by anyone trying to avoid pesticides, but it’s especially important for parents to limit their children’s exposures to these toxic chemicals.
This article on their website has a lot more good information and links to resources. Hope you find these links useful!
