(WASHINGTON) -- An apple a day may keep the doctor away, but how good is that apple if it is laden with pesticides?
According to new report released Monday by the Environmental Working Group, apples are at the top of the advocacy group's list of most contaminated fruits and vegetables.
After testing 53 fruits and vegetables and the amount of chemicals left over after the produce was washed and peeled, the group found that 97.8 percent of all apples tested positive for pesticides and 92 percent of them had traces of two or more pesticides.
Coming in second on the list was celery, with 96 percent of all samples testing positive for pesticides, followed by strawberries in third.
Here is the Environmental Working Group's "Dirty Dozen" list:
6. Nectarines (imported)
7. Grapes (imported)
8. Sweet bell peppers
10. Blueberries (domestic)
12. Kale/collard greens
