The Environmental Working Group is out with an updated list of what it calls the Dirty Dozen Plus — common supermarket foods that are covered in chemicals. This year, the list features first-timers like green beans, kale, and collard greens.
To compile their "shopper's guide to pesticides in produce," researchers analyzed 10 years of USDA and Food and Drug Administration pesticide residue tests on foods that had been washed and peeled.
According to the report, in 2010, 68 percent of food samples still had detectable pesticide residue.
The organization also made a list of the least contaminated produce, called the Clean 15. This includes onions, corn, pineapple, and avocado — all of which have thick peels that make it difficult for pesticides to penetrate.
Here's a look at the "dirtiest" fruits and veggies:
Dirty Dozen Plus:
1. Apples: 98 percent of apples had pesticides
2. Celery: 13 different pesticides were found on a single sample
3. Sweet bell peppers: 15 pesticides were found on a single sample
