Every year the Environmental Working Group analyzes USDA data on tens of thousands of produce samples and publishes two lists that I consider essential reading for anyone trying to eat cleaner without losing their mind at the grocery store.
The Dirty Dozen tells you which fruits and vegetables carry the highest pesticide residue. The Clean 15 tells you which ones are consistently low risk to buy conventional.
This is one of the most practical tools I use when shopping. It takes the guesswork out of when organic is worth the extra cost and when it is not, which matters a lot when clean eating on a real budget.

Why Pesticides in Produce Matter
Pesticide residue on produce has been linked to hormone disruption, neurological effects, and developmental concerns especially in children. For anyone managing a hormone related condition like PCOS or thyroid issues this is worth paying attention to. Not to create anxiety around food but to make informed choices when you can.
The most important thing to know: washing produce reduces surface residue but does not remove systemic pesticides that have been absorbed into the plant tissue itself. For Dirty Dozen items organic is genuinely the safer choice.
New for 2026: PFAS Forever Chemicals in Produce
This year EWG added something new to their analysis and it is worth stopping on.
For the first time EWG detected PFAS pesticides on 63% of all Dirty Dozen produce samples. PFAS are known as forever chemicals because they do not break down in the environment or in your body. The most commonly detected PFAS pesticide was fludioxonil, found on nearly 90% of peach samples. A total of 203 different pesticides were detected across all 12 Dirty Dozen crops.
This does not change the list dramatically but it adds important context for why these 12 items in particular are worth prioritizing for organic when you can.
2026 Dirty Dozen: Buy These Organic
The 2026 list is based on 54,344 USDA samples tested after washing and preparation. These residues remained even after the produce was cleaned.
- Spinach — highest pesticide load of any produce tested, average of 7+ pesticides per sample
- Kale, collard and mustard greens — moved up from number 3 in 2025
- Strawberries — nearly all samples tested positive for multiple residues
- Grapes
- Nectarines
- Peaches — nearly 90% of samples contained fludioxonil, a PFAS forever chemical
- Cherries
- Apples
- Blackberries — averaged 4 or more pesticides per sample
- Pears
- Potatoes — 90% of samples contained chlorpropham, a sprout inhibitor banned in the EU
- Blueberries
EWG also specifically highlighted green beans and bell peppers as worth noting due to high overall pesticide toxicity, even though they did not make the official twelve.
If you can only prioritize a few items for organic, start with spinach, kale and greens, strawberries, peaches and grapes. Those five carry the heaviest loads year after year.
2026 Clean 15: OK to Buy Conventional
Almost 60% of Clean 15 samples tested with no detectable pesticide residue at all. The Clean 15 list remained unchanged from 2025 to 2026 which is a good sign that these crops are consistently low risk.
- Avocados — nearly 98% of samples showed no detectable pesticides
- Sweet corn — note: some US sweet corn is GMO, buy organic if you want to avoid that
- Pineapple
- Papaya — note: some US papaya is GMO, buy organic if preferred
- Onions
- Frozen sweet peas
- Asparagus
- Cabbage
- Cauliflower
- Watermelon
- Mangoes
- Bananas
- Carrots
- Mushrooms
- Kiwi
Avocados and sweet corn had the cleanest results with less than 2% of samples showing any detectable pesticides. The thick peel on avocados, pineapple and bananas does a lot of protective work.
How I Actually Use These Lists
I do not stress about being perfect with this. If organic strawberries are double the price and I am already stretching the grocery budget that week I might skip them. If the conventional avocados look better than the organic ones I grab the conventional ones without a second thought.
The goal is to use this as a tool not a source of anxiety. Prioritize organic for the items your family eats most often. Do not let the perfect be the enemy of the good. Eating conventional broccoli is infinitely better than not eating broccoli at all.
Save this post or screenshot the lists to pull up next time you are at the grocery store.
Do better. Not perfect.
