Which Produce Is Actually Worth Buying Organic? 

Buying everything organic gets expensive fast.

If you’re only going to buy some produce organic, it helps to know where the extra cost is most likely to make a meaningful difference.

The answer is not quite as simple as following the Dirty Dozen. Some foods consistently carry more pesticide residue, while others stand out because of the particular pesticides involved. Below, we’ll use the best available data to show which produce is most worth prioritizing organic—and where you can probably save your money.

The Produce Most Worth Buying Organic

If you only want to buy some of your produce organic, the table below shows the foods the latest data suggests are most worth prioritizing.

These foods rise to the top because their conventional versions tend to carry a higher overall pesticide burden, contain residues of greater toxicological concern, or both. In other words, this is where choosing organic is most likely to make the biggest difference to your pesticide exposure.

This is not a claim that conventional produce is unsafe. USDA found that more than 99% of foods tested in 2024 had pesticide residues below established EPA tolerances.

The evidence also is not precise enough to say that #1 is definitively more important for your health than #2 or #3. The ranking is best used as a practical guide to which foods to prioritize first if reducing pesticide exposure is your goal.

One limitation is that the underlying data are not equally recent. Apples, blackberries and potatoes include USDA samples collected in 2024, while the latest data for strawberries, spinach, cherries and nectarines are roughly a decade old. That does not necessarily change which group they belong in, but it makes their exact position today less certain.

Why Potatoes Are a Different Case

Potatoes are a good example of why simply counting how many different pesticides are detected can be misleading.

In USDA’s 2024 testing, 98.3% of potatoes contained at least one detectable pesticide, but most contained only one or two. The overwhelming reason was chlorpropham, a chemical used after harvest to stop stored potatoes from sprouting. It was detected on 169 of the 177 potatoes tested—95.5% of samples.

Among samples where chlorpropham was detected, the average concentration was about 3.5 parts per million, considerably higher than the trace concentrations measured for many other pesticide-food combinations. Note that this was still well below the EPA tolerance for chlorpropham on potatoes of 30 ppm, however.

But it does make potatoes a useful candidate if your goal is simply to reduce pesticide exposure. Instead of buying organic to avoid a complicated mixture of many different residues, as might be the case with berries or leafy greens, the potential benefit here is largely reducing exposure to one very common post-harvest chemical.

Why Peppers and Green Beans Also Deserve Attention

Bell peppers and green beans sit just outside EWG’s Dirty Dozen, but both stand out when pesticide toxicity is considered, not just how many residues are detected.

For peppers, nearly half of conventional U.S. samples in this Consumer Reports analysis contained oxamyl or its breakdown product, which contributed heavily to their risk score.

For green beans, only about 4% of conventional U.S. samples contained acephate and/or methamidophos, but these more toxicologically significant pesticides were enough to drive much of the estimated risk for the crop.

Produce That May Be Worth Buying Organic Depending on How Much You Eat

Not every fruit or vegetable fits neatly into a “buy organic” or “save your money” category.

Foods such as lettuce, cucumbers, celery, tomatoes, cherry tomatoes, oranges, tangerines, plums, raspberries, grapefruit, squash, snap peas, eggplant, sweet potatoes, cantaloupe, broccoli and watermelon generally fall somewhere between the higher- and lower-priority groups.

For these foods, how much you personally eat becomes more important. If you eat cucumbers occasionally, paying extra for organic is unlikely to make a large difference to your overall pesticide exposure. If you eat them every day, that repeated exposure becomes more relevant.

There can also be meaningful differences within a category. Recent USDA testing, for example, found pesticide residues considerably more often on leaf lettuce than on head lettuce.

So there is no strong reason to automatically buy everything in this group organic. Prioritize the foods you eat frequently or in large amounts, particularly after you have covered the higher-priority foods in your diet.

Produce Where Organic Is Usually Less Worth the Extra Cost

Conventional versions of some produce have a much lower pesticide burden. If your organic budget is limited, these are usually the places where paying extra makes less sense purely for reducing pesticide exposure. 

EWG’s 2026 analysis found that almost 60% of samples across its Clean Fifteen had no detectable pesticide residues, while only 16% contained two or more pesticides. Pineapple, sweet corn, avocado and onions were among the foods with the lowest overall scores for both pesticide burden and toxicity.

Frozen sweet peas, asparagus, cabbage, cauliflower, mangoes, bananas, carrots, mushrooms and kiwi also generally fall into the lower-priority group based on current pesticide monitoring. 

The clearest places to save money are probably pineapple, sweet corn, avocado and onions, because their low-priority status is supported by relatively recent USDA testing rather than older monitoring alone.

Papaya also ranks very low in EWG’s current analysis, although the USDA data behind that ranking are from 2011–12. 

None of this means buying these foods organic provides no benefit. Organic versions will generally reduce exposure further. It simply means that, if you are choosing where to spend a limited organic-food budget, there are more compelling places to spend it first.

How to Prioritize Organic Produce on a Budget 

You do not need to buy every food in the higher-priority group organic.

A better approach is to start with the foods from that group that you eat most often. Pesticide exposure depends not just on what is present on a food, but also on how much of that food you regularly eat.

If you eat apples every day but cherries only a few times each summer, organic apples are probably the more meaningful place to spend the extra money. The same applies to someone who eats spinach or blueberries almost daily.

Once you have covered the higher-priority foods you eat frequently, you can consider the more moderate group if your budget allows. Foods in the lower-priority group—such as avocado, pineapple, sweet corn and onions—are usually the last place I would spend extra purely for pesticide-exposure reduction.

The simplest rule is:

Prioritize organic versions of the higher-residue foods you eat most often, rather than trying to buy everything organic.

Why Our List Isn’t Exactly the Dirty Dozen

EWG’s Dirty Dozen is a useful starting point, but it is not quite the same thing as asking which produce is most worth buying organic.

The current EWG methodology is more sophisticated than simply counting pesticide detections. It combines four factors: how often residues are found, how many different pesticides are detected, the total concentration of those residues, and their toxicity. Those four measures are combined into a score, and the 12 highest-scoring foods become the Dirty Dozen.

That is useful information, but the cutoff at 12 is still just a cutoff. There is no biological reason why the food ranked 12th should automatically be worth buying organic while the food ranked 13th should not. 

The underlying USDA data also vary considerably in age, with some crops based on recent monitoring and others still relying on samples collected roughly a decade ago. That adds uncertainty to any exact ranking.

For that reason, I think the Dirty Dozen is best treated as a useful guide rather than a hard dividing line. The more practical question is whether choosing organic for a particular food is likely to make a meaningful difference to the pesticide exposure in your own diet.

Does Washing or Peeling Change the Answer?

Sometimes, but usually not enough to completely change which foods are worth prioritizing organic.

Washing produce under running water can remove some pesticide residues from the surface, and peeling can reduce exposure further for certain fruits and vegetables. But the effect varies widely depending on the pesticide and the food. Some residues sit mostly on the surface, while others can penetrate the skin or be absorbed into plant tissue, where washing has much less effect.

One important detail is that USDA pesticide testing generally prepares produce in ways that resemble normal consumer use before analysis. Foods may be washed, peeled or trimmed depending on how they are typically eaten. So when residues are still detected in USDA data, they often represent what remains after ordinary preparation, not what is sitting on completely unwashed produce.

That means washing is still worth doing, but it is not a reliable substitute for choosing organic if your goal is to reduce pesticide exposure further.

Peeling can make a bigger difference for some foods, but it also removes edible parts of the fruit or vegetable and is not practical for foods such as berries, leafy greens or grapes.

Bottom Line

So, which produce is actually worth buying organic?

If your goal is to reduce pesticide exposure without paying the organic premium for everything, start with the higher-priority foods you eat most often—especially leafy greens, berries, apples, peaches, pears, grapes, potatoes, peppers and green beans.

Foods such as avocado, pineapple, sweet corn and onions are usually lower priorities because conventional versions tend to carry much less pesticide residue after normal preparation.

The simplest approach is to be selective: buy organic where it is most likely to reduce your exposure, and save your money where the difference is smaller.
