OK, so there are a few different opinions about foods that need to be on "irty Dozen" list. It seems, though, that no matter what list you read, the main culprits remain the same:
Apples Cherries Grapes Peaches Nectarines Pears Lettuce Strawberries Bell peppers Celery Potatoes Spinach
Lists often vary to include the following:
Raspberries Beef Poultry Dairy
The above fruits and vegetables are considered the "irty Dozen" because they have the tendency to retain a higher level of pesticides and herbicides used by farmers than other types of produce. But no matter where they are from, peaches are the worst culprit and number one on the "irty Dozen" list, with a FDA residual chemical rating of 100. This means, of all the produce on the list, peaches retain the highest amount of harmful residual chemicals.

Of course, ideally you are buying everything local and organic, but not everyone can afford to do this, so this list is just of recommendations that are particularly important.
Does anyone have any other items on their personal "dirty dozen" list?
I once heard a corollary to this. Apparently, pineapple doesn't take in much pesticide. So if you visit a conventional pineapple farm in hawaii, it will reek of toxic gick: they use more because they are allowed to. They are allowed to because the plant takes up less.
