The Environmental Working Group has just put out their fifth edition of the classic, "Shopper's Guide to Pesticides" including the Dirty Dozen and the lesser known Clean 15. This is a great way to find out which fruits and veggies you should go organic on and which are fine if they're grown conventionally. There's even a handy wallet-sized guide you can take to the store with you for quick reference. Find out the top five offenders below...

They analyzed 47 fruits and vegetables and you can view the complete list here. The worst:
1 Peach 100 (highest pesticide load)
2 Apple 93
3 Sweet Bell Pepper 83
4 Celery 82
5 Nectarine 81
