An independent analysis conducted by S.D. Savage discussed in his blog Applied Mythology http://appliedmythology.blogspot.com/ with a more detailed description here http://www.scribd.com/doc/142002990/An-Independent-Analysis-of-the-2011-USDA-Pesticide-Residue-Data shows that it is quite safe to eat vegetables and fruits as they contain few pesticide residues. It really does not matter much if these were produced conventionally or organically, they are quite safe.
In fact as S.D. Savage points out in his analysis
For all 20 commodities tested from 2011, there were only 0.18% of residues found which were higher than the EPA tolerance. In fact fully 1/2 of the detections were of levels more than 100 times lower than the already conservative tolerance.
