"An apple a day usually keeps the doctor away -- unless it's ridden with pesticides.

For the 10th year in a row, nonprofit advocacy agency the Environmental Working Group (EWG) has released its list of the most pesticide-contaminated produce, and once again apples top the Dirty Dozen.

The Dirty Dozen, part of the EWG's yearly Shopper's Guide to Pesticides in Produce, is compiled from U.S. Department of Agriculture data on 48 fruits and veggies with pesticide residue data. About 65 percent of the produce samples test positive.

That's bad news for a few reasons: Pesticides have been linked to developmental problems in children, and may act as carcinogens or throw off the endocrine system, according to the U.S. Environmental Protection Agency."
