Quick answer: The EWG's 2025 Dirty Dozen identifies strawberries, spinach, and kale/collard greens/mustard greens as the three most pesticide-contaminated produce items. Up to 54 different pesticide residues have been found on a single Dirty Dozen item. If your budget is tight, prioritize buying organic for Dirty Dozen items and save money by buying conventional Clean Fifteen produce like avocados, sweet corn, and pineapple.
Every year, the Environmental Working Group (EWG) analyzes pesticide testing data from the USDA and FDA to publish two lists that every parent should know: the Dirty Dozen and the Clean Fifteen. These lists rank the most common fruits and vegetables by how much pesticide residue they carry after being washed and prepared the way people normally eat them.
We used this data to build our free Pesticide Lookup Tool, and we wanted to break it all down in one place so you can reference it anytime - at the grocery store, at the farmer's market, or when you're meal planning for the week.
Here's what the 2025 data actually shows, what it means for your family, and the practical steps we take to reduce our kids' pesticide exposure without breaking the budget.
What Is the Dirty Dozen?
The Dirty Dozen is the EWG's annual ranking of the 12 fruits and vegetables with the most pesticide residue. The data comes from the USDA's Pesticide Data Program and FDA testing - over 46,000 samples of conventionally grown produce tested each year.
Here's the important part: these samples are tested after being washed and peeled (when applicable), just like you'd prepare them at home. So the pesticide residues found are what you and your kids are actually eating, not what's on the produce at the farm.
The EWG has published this list every year since 2004. It's the most widely cited pesticide reference guide in the US, and it's the data source behind our Pesticide Lookup Tool.
The 2025 Dirty Dozen List
These are the 12 most pesticide-contaminated fruits and vegetables in 2025, ranked from worst to slightly-less-worst. For each item, we've included the number of different pesticide residues detected by USDA testing. Buy organic for all of these when you can.
| Rank | Produce | Pesticides Found | Key Concern |
|---|---|---|---|
| 1 | Strawberries | 54 pesticides | Over 90% of samples tested positive for residues. Multiple hormone-disrupting chemicals detected. |
| 2 | Spinach | 52 pesticides | High levels of permethrin, a neurotoxic insecticide. 97% of samples had residues. |
| 3 | Kale, Collard & Mustard Greens | 103 pesticides | The highest total number of pesticides of any item. DCPA (Dacthal) detected - classified as a possible carcinogen. |
| 4 | Grapes | 35 pesticides | Multiple fungicides detected. Thin skin means pesticides penetrate easily. |
| 5 | Peaches | 46 pesticides | Over 99% tested positive for at least one pesticide. Fludioxonil (fungicide) commonly found. |
| 6 | Pears | 51 pesticides | High number of different residues. Multiple insecticides and fungicides detected. |
| 7 | Nectarines | 36 pesticides | Nearly 94% tested positive. Similar pesticide profile to peaches. |
| 8 | Apples | 47 pesticides | Over 90% contained residues. Diphenylamine (a post-harvest chemical) frequently detected. |
| 9 | Bell & Hot Peppers | 75 pesticides | Second-highest total number of pesticides. Includes organophosphate and carbamate insecticides, which are especially toxic to children's nervous systems. |
| 10 | Cherries | 42 pesticides | Over 90% tested positive. Multiple systemic pesticides that cannot be washed off. |
| 11 | Blueberries | 54 pesticides | Tied with strawberries for pesticide variety. Phosmet (organophosphate) detected in some samples. |
| 12 | Green Beans | 37 pesticides | Acephate and methamidophos detected - organophosphates banned on some crops but still found on green beans. |
A few things jump out from this data. Kale, collard greens, and mustard greens had the highest total number of pesticides detected at 103. Bell and hot peppers came in second at 75. These are staggering numbers - and remember, this is after washing.
Strawberries have topped or nearly topped the Dirty Dozen list for years. They grow close to the ground, have no protective peel, and are heavily sprayed during their growing season. If there's one item you should always buy organic, it's strawberries - especially if your kids eat them regularly.
The 2025 Clean Fifteen List
The Clean Fifteen are the 15 fruits and vegetables with the lowest pesticide residue. These are your budget-friendly options when you can't afford to buy everything organic. Many of these tested with no detectable pesticides at all.
| Rank | Produce | % Tested Clean | Why Lower Risk |
|---|---|---|---|
| 1 | Avocados | 99% | Thick, inedible skin provides a natural barrier. Almost no detectable residue. |
| 2 | Sweet Corn | 98% | Husk protects the kernels. Note: buy organic to avoid GMO varieties. |
| 3 | Pineapple | 96% | Thick, tough rind that you don't eat provides excellent protection. |
| 4 | Onions | 97% | Multiple papery layers are removed before eating. Natural pest resistance. |
| 5 | Papaya | 95% | Thick skin that you peel off. Note: buy organic to avoid GMO varieties. |
| 6 | Frozen Sweet Peas | 95% | Pod provides a protective layer. Blanching before freezing may reduce residues further. |
| 7 | Asparagus | 94% | Naturally pest-resistant. Fewer pesticides used during growing. |
| 8 | Honeydew Melon | 93% | Thick rind protects the fruit. You eat only the interior flesh. |
| 9 | Kiwi | 93% | Fuzzy skin acts as a natural barrier and is typically peeled. |
| 10 | Cabbage | 92% | Outer leaves are typically removed before eating, taking residue with them. |
| 11 | Mushrooms | 93% | Often grown indoors with minimal pesticide use. Very few residues detected. |
| 12 | Mangoes | 91% | Thick skin that you don't eat. Peeling removes most surface contamination. |
| 13 | Watermelon | 91% | Very thick rind provides strong protection for the flesh inside. |
| 14 | Sweet Potatoes | 90% | Grow underground with fewer pest pressures. Skin is typically peeled or provides a barrier. |
| 15 | Carrots | 89% | Grow underground with natural soil protection. Peeling removes surface residues. |
The pattern is clear: produce with thick peels, rinds, or husks that you remove before eating tends to have far less pesticide residue. Avocados, pineapple, and sweet corn are consistently the cleanest items year after year.
Two important notes on the Clean Fifteen: sweet corn and papaya may be grown from genetically modified seeds. If avoiding GMOs is important to your family, buying organic for these two items guarantees non-GMO, since USDA organic certification prohibits genetic modification.
Health Concerns from Pesticide Exposure
This isn't about fear-mongering. It's about understanding what the research actually shows so you can make informed decisions for your family. Here are the documented health effects associated with pesticide exposure, particularly relevant for young children and pregnant women.
Hormone Disruption
Many common pesticides are endocrine disruptors, meaning they interfere with your body's hormone systems. This includes estrogen, testosterone, and thyroid hormones. For developing children, even small disruptions to hormone signaling can affect growth, puberty timing, and reproductive development. Pesticides like atrazine, chlorpyrifos, and certain fungicides have demonstrated endocrine-disrupting effects in peer-reviewed research.
Neurological Effects
Organophosphate pesticides - found on several Dirty Dozen items including bell peppers, green beans, and blueberries - work by disrupting nerve signaling. That's how they kill insects. The concern is that developing brains are far more vulnerable to this mechanism than adult brains. The American Academy of Pediatrics has noted associations between organophosphate exposure and decreased cognitive function, behavioral problems, and attention issues in children.
Cancer Risk
Several pesticides detected on Dirty Dozen produce are classified as possible or probable carcinogens by the International Agency for Research on Cancer (IARC) or the EPA. DCPA (Dacthal), found on kale and other greens, is classified as a possible human carcinogen. While the risk from any single exposure is small, the cumulative effect of daily exposure across multiple produce items over years is what concerns researchers.
Children Are More Vulnerable
This is the part that matters most to us as parents. Children face higher risk from pesticide exposure for several reasons:
- They eat more per pound of body weight - a toddler eating one strawberry gets a proportionally higher dose than an adult eating the same strawberry
- Their detoxification systems are immature - children's livers and kidneys are still developing and less efficient at processing chemicals
- Their brains are still developing - neurological effects are more consequential during critical development windows
- They eat more fruits and vegetables proportionally - which is exactly what we want them to do, but it increases exposure
Which Produce to Always Buy Organic
If you can only afford to buy some produce organic, here is our priority list based on the 2025 data. We've broken it into tiers to make grocery shopping easier.
Always Buy Organic (Highest Priority)
- Strawberries - 54 pesticides, over 90% test positive, kids' favorite fruit
- Spinach - 52 pesticides, neurotoxic insecticide residues, common in baby food and smoothies
- Kale and leafy greens - 103 total pesticides detected, often eaten raw in smoothies and salads
- Apples - 47 pesticides, one of the most commonly eaten fruits by children
- Blueberries - 54 pesticides, popular in kids' snacks and breakfast
Buy Organic When Available (High Priority)
- Grapes - 35 pesticides, thin skin, no peeling
- Peaches and nectarines - 46 and 36 pesticides respectively, soft skin absorbs residues
- Cherries - 42 pesticides, systemic pesticides that can't be washed off
- Pears - 51 pesticides, frequently consumed by families
- Bell peppers - 75 pesticides, includes organophosphates
OK to Buy Conventional (Lower Priority)
- Avocados, pineapple, onions - thick peels or layers you remove
- Sweet corn - protected by husk (buy organic if avoiding GMOs)
- Cabbage, asparagus, mushrooms - naturally lower pesticide residue
- Watermelon, honeydew, mangoes, kiwi - thick rind or skin provides protection
- Sweet potatoes, carrots - underground growing and peeling reduce exposure
How to Reduce Pesticide Exposure
Buying organic for everything would be ideal, but it's also expensive. Here are practical strategies we use to reduce our family's pesticide exposure without doubling our grocery bill.
Washing Tips That Actually Work
Let's be clear: washing produce under running water does help, but it doesn't remove everything. Studies show water alone removes roughly 30-50% of surface residues. Here's how to maximize what washing can do:
- Run under cold water for at least 30 seconds while gently rubbing the surface. This is more effective than a quick rinse.
- Use a produce wash spray for better results. Lab-tested produce washes can remove up to 99.9% of surface pesticide residue - far more effective than water alone.
- Soak leafy greens for 2-3 minutes in cold water, then rinse. This gives residues time to dissolve off the leaves.
- Use a clean brush on firm produce like apples, cucumbers, and potatoes. Scrubbing physically removes residue from the surface.
- Peel when possible - peeling removes surface residues entirely, though you lose some nutrients in the skin.
The important caveat: systemic pesticides are absorbed into the plant through its roots and vascular system. No amount of washing or peeling can remove them. This is one of the strongest arguments for buying organic, especially for Dirty Dozen items where systemic pesticides are commonly used.
Smart Shopping Strategies
- Shop farmer's markets - many local farms use organic or low-spray practices even without formal certification. Ask the grower directly about their pest management.
- Buy frozen organic - frozen organic produce is often cheaper than fresh organic and locks in nutrients at peak ripeness.
- Check store brands - many grocery store brands (Kirkland, 365 by Whole Foods, Simple Truth) offer organic at lower prices than name brands.
- Buy in season - organic produce costs less during peak season when supply is high.
- Use the Clean Fifteen strategically - save money by buying conventional for low-pesticide items and redirect that budget toward organic Dirty Dozen items.
Products That Help Reduce Pesticide Residue
Can't always buy organic? These products help reduce pesticide residue on conventional produce. We use both of these in our kitchen.
Eat Cleaner Fruit + Veggie Wash
Lab-tested to remove up to 99.9% of surface pesticide residue, wax, and soil. Works in 60 seconds - just spray, rub, and rinse. Made from plant-based ingredients. Much more effective than water alone at removing chemical residues from produce.
Rubbermaid FreshWorks Produce Storage
Keeps produce fresh up to 80% longer with a built-in FreshVent filter that regulates oxygen and CO2. When organic produce costs more, the last thing you want is it going bad before you eat it. Dishwasher safe and BPA free.
Tips for Parents on a Budget
We hear this a lot: "We can't afford to buy everything organic." Honestly, neither can we. Here's the good news - you don't have to. The EWG's data shows that strategically choosing which items to buy organic makes a real difference. Here's our practical approach.
The 80/20 Rule for Organic Shopping
You can eliminate the vast majority of your family's pesticide exposure by buying organic for just the Dirty Dozen and buying conventional for the Clean Fifteen. You don't need a 100% organic grocery cart to make a meaningful impact. Focus your organic budget where it matters most:
- Any berries your kids eat regularly - strawberries, blueberries, and raspberries are among the most contaminated produce
- Leafy greens - especially if you make smoothies, salads, or use spinach in cooking frequently
- Apples - one of the most commonly eaten fruits by kids, and consistently high on the Dirty Dozen
Budget-Friendly Organic Sources
- ALDI - has a growing organic section at significantly lower prices than specialty stores
- Costco/Kirkland Organic - bulk organic produce and frozen organic fruits/vegetables at warehouse prices
- Frozen organic - often 30-50% cheaper than fresh organic and nutritionally equivalent
- CSA boxes - Community Supported Agriculture programs often provide organic produce at below-retail prices
- Grow your own - even a small container garden with strawberries, herbs, and greens eliminates pesticide exposure for those items entirely
The Most Important Thing
Here's something the EWG itself emphasizes: eating fruits and vegetables - even conventional ones - is always better than not eating them. The health benefits of a produce-rich diet far outweigh the risks from pesticide residues. Don't let concerns about pesticides stop you from feeding your kids their fruits and vegetables. The goal is to reduce exposure where you can, not to create food anxiety.

The Bottom Line
The 2025 Dirty Dozen data confirms what we've seen in recent years: strawberries, spinach, and leafy greens remain the most pesticide-contaminated produce, with up to 103 different pesticide residues detected on a single item. The Clean Fifteen - led by avocados, sweet corn, and pineapple - offers a much safer conventional option, with some items testing nearly 100% clean.
Our approach as parents: we buy organic for Dirty Dozen items (especially the berries, greens, and apples our kids eat daily), we buy conventional for Clean Fifteen items to save money, we wash everything with a produce wash, and we store organic produce in FreshWorks containers so nothing goes to waste.
It doesn't have to be all-or-nothing. Every organic swap you make reduces your family's pesticide exposure. Start with the items your kids eat the most, and go from there.
