Continuing Dan Shapley's comments at thedailygreen.com on the 12 fruit and veg most highly affected by pesticides.
Another tree fruit that always makes the dirty dozen list: peaches. more than
60 pesticides have been found on peaches, an nearly as many in single-serving packs, but far fewer
in canned peaches.
Safer alternatives include watermelon, tangerines, oranges and grapefruit.
Leading the leafy green pesticide residue category is spinach, with nearly
50 different pesticides. (While frozen spinach has nearly as many, canned has had fewer detected pesticides.)
