The Dirty Dozen and Clean Fifteen of 2021

Since its inception in 1993, Environmental Working Group (EWG) has fought for “consumers’ right to have healthier lives in a healthier environment. The group is credited with its pivotal role in Congress’ passage of the Food Quality Protection Act of 1995 

Every year since 2004, EWG tests fruits and vegetables on the market with respect to quantity and severity of harmful biocides pesticide or herbicide apt to affect pollinators, soil biota, and consumers — measuring the residue present after the food is prepared to eat. With the assumption that washing and peeling, if appropriate, removes the bulk of the biocides, EWG updates yearly their “Dirty Dozen and Clean Fifteen” list. The list informs which of the 46 tested fruits and veggies consumers should definitely buy organic, and which ones are low risk when bought from an industrial grower. 

The Dirty Dozen 

This year’s report again highlights strawberries and spinach as the long-time dirtiest of the dirty dozen, followed by a group: kale, collards, and mustard greens. Then, in order of decreasing residue, the list cites nectarines, apples, grapes, cherries, peaches, pears, bell and hot peppers, celery, ending with tomatoes.  

Places thirteen through thirty are occupied by produce with a medium level of biocides. In decreasing level of residue those are: potatoes, cherry tomatoes, lettuce, blueberries, cucumbers, plums, green beans, tangerines, grapefruits, raspberries, snap peas, oranges, carrots, winter squash, summer squash, bananas, sweet potatoes, and watermelon, bringing up the rear. 

The Clean Fifteen starts at place thirty-one 

In order of decreasing levels of biocide residue, we have the cleanest fifteen items: mangoes, cantaloupe, honeydew melon, mushrooms, cauliflower, kiwi, cabbage, broccoli, asparagus, eggplant, sweet peas (frozen), papaya, onions, pineapple, sweet corn… ending with avocados as the cleanest.
