WASHINGTON, MARCH 26, 2026 —
What You Need To Know
- 96% of Dirty Dozen produce samples tested positive for pesticides — even after being washed and peeled, exactly as you would at home
- For the first time in the guide’s 22-year history, “forever chemicals” known as PFAS were found in 63% of all Dirty Dozen samples — chemicals linked to cancer, thyroid disease, and reproductive harm
- Spinach tops the list as the most contaminated produce — but the single most practical thing most Americans can do costs nothing: know the list before you shop
Every year since 2004, the Environmental Working Group has released the same guide. Every year, millions of American families read it, share it, and then largely forget it by the time they reach the produce aisle. The 2026 edition is different enough to pay attention to — because for the first time in the guide’s history, the most commonly detected pesticides on America’s fruits and vegetables are not just pesticides. They are forever chemicals.
The Environmental Working Group’s 2026 Shopper’s Guide to Pesticides in Produce, released Tuesday, analyzed the most recent USDA pesticide residue testing across 54,344 samples of 47 different fruits and vegetables. The results are not comfortable reading for anyone who feeds children.
The 2026 Dirty Dozen — Full List
| Rank | Produce | Key Finding |
|---|---|---|
| 1 | Spinach | Most pesticide residue by weight — avg 4+ pesticide types |
| 2 | Strawberries | Perennial top-two — detected on nearly every sample |
| 3 | Grapes | High residue levels — popular with children |
| 4 | Nectarines | 90% of samples contained PFAS pesticide fludioxonil |
| 5 | Peaches | 90% of samples contained PFAS pesticide fludioxonil |
| 6 | Cherries | Multiple pesticide types per sample |
| 7 | Apples | Consistently high across multiple pesticide categories |
| 8 | Blackberries | Imported samples showed organophosphate residues |
| 9 | Pears | High pesticide variety per sample |
| 10 | Potatoes | Lower variety — avg 2 pesticides — but high volume consumed |
| 11 | Blueberries | Rising contamination — new to top positions |
| 12 | Kale/Collard/Mustard Greens | High toxicity score despite moderate residue levels |
EWG also flagged green beans and bell and hot peppers as items that ranked just outside the Dirty Dozen but scored highly on overall toxicity — meaning families who eat those regularly should treat them with the same caution.
The Forever Chemicals Finding — What It Actually Means
The headline that set this year’s guide apart from every previous edition was the detection of PFAS pesticides on more than 63% of all Dirty Dozen samples — the first time EWG has highlighted this category of chemical contamination in its 22 years of publishing the guide.
PFAS — per- and polyfluoroalkyl substances — are a class of approximately 15,000 synthetic chemicals that share one defining characteristic: they do not break down. Their molecular bonds persist in the environment for decades or centuries. They persist in human blood and tissue for years after exposure. And they have been linked by the EPA and independent researchers to cancer, thyroid disease, high cholesterol, decreased fertility, liver damage, hormone disruption, and immune system damage.
The three most frequently detected PFAS pesticides on produce were fludioxonil, fluopyram, and bifenthrin. Fludioxonil alone appeared in 14% of all produce samples tested — and in nearly 90% of peach and plum samples. All three are legal for agricultural use in the United States. All three have been banned or heavily restricted in the European Union on health safety grounds.
The reason PFAS pesticides end up on produce is straightforward: they work. PFAS-based fungicides and insecticides are highly effective at killing the molds, fungi, and insects that destroy crops. The fact that they also persist indefinitely in the environment and accumulate in human tissue has not, to date, been sufficient grounds for U.S. regulators to remove them from the market.
The 2026 Clean Fifteen — Safer Choices
The same report that identifies the most contaminated produce also identifies the least — and the contrast is striking.
| Rank | Produce | Finding |
|---|---|---|
| 1 | Avocados | Nearly zero pesticide residues |
| 2 | Sweet Corn | Near-zero detections |
| 3 | Pineapple | Near-zero detections |
| 4 | Onions | Very low contamination |
| 5 | Papaya | Low contamination |
| 6 | Frozen Sweet Peas | Low contamination |
| 7 | Asparagus | Low contamination |
| 8 | Cabbage | Low contamination |
| 9 | Cauliflower | Low contamination |
| 10 | Watermelon | Low contamination |
| 11 | Mangoes | Low contamination |
| 12 | Bananas | Low contamination |
| 13 | Carrots | Low contamination |
| 14 | Mushrooms | Low contamination |
| 15 | Kiwi | Low contamination |
Nearly 60% of Clean Fifteen samples had no detectable pesticide residues at all — compared to 96% of Dirty Dozen samples that tested positive.
What the Critics Say — And Why It Matters
The EWG’s annual guide is not without controversy. A number of food scientists and regulatory toxicologists argue that the Dirty Dozen methodology overstates health risks by measuring the presence of pesticide residues without adequately accounting for the dose at which those residues actually pose harm to human health. The FDA and EPA both set legal pesticide tolerance levels designed to ensure that residues on produce remain well below thresholds associated with harm.
The counterargument — which EWG and a growing number of independent researchers make — is that those tolerance levels were often set years or decades ago, frequently based on incomplete data, and that regulators assess pesticides individually rather than as the chemical mixtures that consumers are actually exposed to when eating multiple Dirty Dozen items across a week. Animal studies, EWG notes, indicate that combined exposures to multiple pesticides can be significantly more harmful than exposure to any single chemical in isolation.
The PFAS finding adds a new dimension to this debate. PFAS chemicals are bioaccumulative — meaning they build up in the body over time rather than being processed and excreted. A single serving of strawberries with trace PFAS residue is unlikely to cause measurable harm. A lifetime of regular consumption across multiple PFAS-contaminated produce items is a different calculation — and one that existing regulatory frameworks were not designed to assess.
What Most People Miss
Point 1: Washing produce does not remove PFAS. The EWG tests were conducted after produce had already been washed and peeled using methods that mimic standard consumer behavior. The residues detected survived that process. For PFAS specifically — which bond chemically to produce rather than simply sitting on the surface — washing provides minimal protection.
Point 2: Frozen organic produce is often cheaper than fresh organic and retains comparable nutritional value. For families trying to reduce pesticide exposure on a budget, frozen organic strawberries, blueberries, and spinach are a practical and affordable alternative to fresh conventional versions.
Point 3: The Clean Fifteen items with near-zero contamination — avocados, pineapples, sweet corn, and onions — have a natural advantage: thick outer skins or husks that are removed before eating. The edible portion never directly contacts whatever is sprayed on the outside. This is why avocados consistently top the Clean Fifteen while thin-skinned strawberries consistently top the Dirty Dozen.
Your Next Move
Save this list on your phone before your next grocery trip. For the 12 Dirty Dozen items your family eats regularly, choose organic versions when available and affordable. For the Clean Fifteen, conventional is fine — the contamination data simply does not support the premium cost of organic for those items. If budget constraints force a choice, prioritize organic for the items your children eat most frequently — strawberries, grapes, and apples are perennial favorites among kids and perennial leaders on the Dirty Dozen.
The goal is not to stop eating fruits and vegetables. The American Academy of Pediatrics is explicit on this — produce is essential for health at every age, and the benefits of eating it far outweigh the risks of pesticide residue for the vast majority of people. The goal is to make informed choices. The 2026 Dirty Dozen gives you exactly the information you need to do that.
