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.
2026 Dirty Dozen — Buy These Organic
Spinach took the top spot this year, bumping strawberries to second place after nine years at number one. New additions in 2025 were blackberries and potatoes. Blackberries showed contamination with up to 48 different pesticides. Potatoes often contain chlorpropham, a sprouting inhibitor that is banned in the European Union.
- Spinach
- Strawberries
- Kale, collard and mustard greens
- Peaches
- Pears
- Nectarines
- Apples
- Grapes
- Bell peppers and hot peppers
- Cherries
- Blueberries
- Green beans
- Blackberries — new
- Potatoes — new
2026 Clean 15 — OK to Buy Conventional
Almost 60% of Clean 15 samples tested with no detectable pesticide residue at all. Avocados led the list with nearly 98% of samples showing no detectable pesticides — the thick peel does a lot of protective work. The Clean 15 remained unchanged from 2025 to 2026.
- Avocados
- Sweet corn
- Pineapple
- Onions
- Papaya
- Frozen sweet peas
- Asparagus
- Honeydew melon
- Kiwi
- Cabbage
- Mushrooms
- Mangoes
- Sweet potatoes
- Watermelon
- Cauliflower
- Bananas
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 the graphic to your phone and pull it up next time you are at the grocery store. That is literally what I do.
