A new mobile app is available from The Environmental Working Group is a guide to the fruits and vegetables with the highest and lowest pesticide residues.
“When your budget is tight or organic’s not available, you can use the “Clean 15” and the “Dirty Dozen” lists to determine which conventionally-grown produce items have the highest and lowest amounts of pesticides”
A few of the worst: strawberries, peach, apple, sweet bell pepper, celery, nectarine, donuts, gin & tonics…
The best: onion, avocado, sweet corn, pineapple, mango.
I’ve heard for years that produce with the toughest skins pose the least problems, as the pesticides cannot penetrate, and you peel most of them.
It’s a free application. Search under “dirty dozen” or Environmental Working Group in your app store.
(I added the last two to the “worst” section because I’m trying to convince myself to give them up.)
