These fruits and vegetables have earned their way onto the Environmental Working Group's "Clean Fifteen" list because they've been found to contain the lowest concentration of pesticide load. The ranking system is based on the group's analysis of more than than 60,700 samples taken from 2000 to 2010 by the U.S. Department of Agriculture and the U.S. Food and Drug Administration.
