Pesticide Alert: The Dirtiest Foods You're Probably Eating

Bad news for French-fry aficionados: potatoes were found to have more pesticides by weight than any other fruit or vegetable. Sweet potatoes, however, have relatively few pesticides.

If you can't find organic celery, consider substituting another vegetable instead. After being tested by the Environmental Working Group (a non-profit organization that focus on public health and the environment), celery was ranked the fourth "dirtiest" produce with as many as 13 different pesticide residues.

Buy grapes (and grape-derived produces like raisins and wine) in organic varieties if you can. According to a list compiled by the Environmental Working Group  grapes are the third highest in pesticides.

Strawberries are also notoriously full of pesticides. One report from the U.S. Department of Agriculture found that a single strawberry tested positive for 13 different pesticides. Stick to organic strawberries whenever possible.

Apples almost always top the list of "dirtiest" produce (fruits and vegetables with the most pesticide residue); 98 percent test positive for pesticide residue. Whether you're buying apples, applesauce, or apple juice, always go organic.
