Don’t Eat These 12 Fruits and Vegetables Without Washing Them First [CNET]

These crops are treated with pesticides, which means you’re going to want to do your due diligence before serving them at the dinner table.

Think before you pop that tomato in your mouth as soon as you get home from the grocery. It’s true that veggies can be some of the healthiest foods you put on your plate. But that’s only if you properly wash the vegetables you plan on eating. You never know which produce you bring home will be completely covered in pesticides. And the bad news is that some types are far more apt to be swimming in pesticides than others.

If you’re worried about downing pesticides or other chemicals your food may be exposed to, you’re not alone. There are Reddit threads and forum posts from people who are concerned about how pesticide-treated crops can affect their health. While the common answer seems to be that it depends on the pesticide, you can take matters into your own hands and figure out which foods you should definitely be washing.

To help sort the dirtiest produce from the not-so-bad, food safety nonprofit Environmental Working Group publishes a list of produce most likely to contain pesticides. It’s called the “The Dirty Dozen” and it’s a cheat sheet of which fruits and vegetables you should always wash. 

The group analyzed 46,569 samples of 46 fruits and vegetables that were tested by the US Food and Drug Administration and the Department of Agriculture.

The No. 1 offender of pesticides in the group’s latest study? Strawberries. The popular berries had more total instances of chemicals found on them than any other fruit or vegetable included in the sweeping analysis.

In general, foods that don’t have natural casings or have edible skins such as apples, greens and berries are more likely to contain pesticides. You’ll want to wash these crops or peel away the skin before you take a bite out of them. On the other hand, pieces of produce with commonly removed skin such as avocados and pineapples are far less likely to be tainted.

Below you’ll find the 12 foods most likely to contain pesticides and the 15 foods least likely to be tainted.

The Dirty Dozen: The Fruits and Vegetables to Always Wash

Foods most likely to contain pesticides, according to FDA and USDA data.

1. Strawberries
2. Spinach
3. Kale, collard and mustard greens
4. Peaches
5. Pears
6. Nectarines
7. Apples
8. Grapes
9. Bell and hot peppers
10. Cherries
11. Blueberries
12. Green beans

The Dirty Dozen is a good indicator meant to alert consumers to the fruits and vegetables most in need of thorough washing. Even a quick rinse with water or a spritz of produce wash helps. 

You can also sidestep much of the potential risk by buying certified organic fruits and vegetables that are free from the use of farming pesticides. Knowing which foods are more likely to contain pesticides might help you decide where to spend that bit of extra money on organic. And as I learned in an analysis of organic and nonorganic prices, they aren’t as expensive as you might think.

More takeaways from the Dirty Dozen study

• More than 90% of samples of strawberries, apples, cherries, spinach, nectarines and grapes tested positive for residues of two or more pesticides.
• A total of 210 different pesticides were found on Dirty Dozen items.
• Of those 210, over 50 different pesticides were detected on every type of crop on the list, except cherries.
• Kale, collard and mustard greens, as well as hot peppers and bell peppers, had the most pesticides detected of any crop — 103 and 101 pesticides in total, respectively.

The Clean 15: Fruits and Vegetables You Can Skip Washing

These are the fruits and vegetables least likely to contain pesticides, according to the study:

EWG’s methodology involves six measures of pesticide contamination. The analysis focuses on which fruits and vegetables are most likely to contain one or more pesticides but does not measure how much of any one pesticide is on a given piece of produce.
