The 2024 Dirty Dozen: 12 Foods You Should Buy Organic, According to the Environmental Working Group (2024)

One of the easiest thing you can do to improve your overall health is to eat more fruit and vegetables. The benefits of eating enough produce include lowering your risk of heart disease, improving your brain health and more. The USDA recommends eating 400 grams of produce each day, which is about 5 servings—or 2 cups of fruit and 3 cups of vegetables.

So does it matter if the produce is organic or not? Eating more fruits and vegetables is good for you no matter if its organic or conventional. But if you're concerned about pesticides in your food, then you may choose to buy organic. If you want to buy organic food but the higher costs don't work for your budget, one resource to reference is the Environmental Working Group's (EWG) Shopper's Guide to Pesticides in Produce. Updated annually, the nonprofit organization shares its findings based on testing data from the USDA and Food and Drug Organization. The USDA peels or scrubs and washes fruits and vegetables before testing for pesticide residues, while the FDA only removes dirt.

The guide includes the Dirty Dozen (below), which highlight fruits and vegetables with the highest amount of pesticide resides, and the Clean Fifteen, which has the lowest. If you want to buy organic but your budget doesn't allow, you could prioritize opting for organic versions of the items on the Dirty Dozen and conventional fruits and vegetables on the Clean Fifteen.

More than 99% of the foods USDA sampled in 2022 had residues below tolerance levels established by the Environmental Protection Agency. The EWG can measure the presence of residues but cannot draw conclusions about the danger they may pose. It's also worth nothing that some of the data EWG used to draw its conclusions is more than 10 years old—or older. It's also important to note that the USDA monitors pesticide use and residues in fruits and vegetables. Read below to see the fruits and vegetables on the 2024 EWG's Dirty Dozen list .

1. Strawberries

Strawberries remain at the top of the list as the produce item with the most pesticide residues. According to EWG, more than 99% of the strawberries sampled tested positive for at least one pesticide and 30% had residues of 10 or more.

2. Spinach

Spinach has more pesticide residue by weight (remember spinach leaves weigh very little) compared to any of the other produce tested, according to EWG. Relatively high concentrations of permethrin, a known neurotoxin, were found in 76% of the samples.

3. Kale, Collards and Mustard Greens

4. Grapes

Similar to blueberries, 9 out of 10 of all green bean samples had pesticide residues found, often more than two types, according the EWG.

Should I Only Buy Organic Fruits and Vegetables?

The short answer is no. The most important thing you can do for your overall health is eat more fruits and vegetables, no matter if they're conventional or organic. If you choose to buy organic produce, you may want to prioritize items in this list, since they are higher in pesticide residues. But the bottom line is that more produce is better, so don't let this lists dissuade you from including fruits and vegetables in your eating pattern.
