EWG’s 2021 Dirty Dozen and Clean Fifteen Lists

Published: April 15, 2021
Updated: May 4, 2022

Nearly 70% of fresh, non-organic produce sold in the United States contains residues of pesticides…

That’s the main takeaway from the Environmental Working Group’s (EWG) 2021 analysis of pesticides in produce. 

And it could have implications for your bone health.

That’s because pesticides can be pro-oxidant, which means they produce free radicals in your body. And free radicals can trigger low-grade, chronic inflammation –– an underlying cause of bone loss! 

That’s why we recommend buying organic produce when possible –– because the crops are grown using far fewer synthetic pesticides.

But we totally understand that organic options aren’t always available. Plus, they tend to be more expensive.

That’s where the “Clean Fifteen” and “Dirty Dozen” lists come in! They’ll make it easier for you to decide which conventionally grown foods are less likely to contain high levels of pesticides, and which are worth spending a little extra on to go organic.

The 2021 Dirty Dozen

The following 12 fruits and veggies ranked the worst in this year’s analysis.

The Dirty Dozen List at a Glance:

  • This year’s dirty dozen is very similar to last year’s. The only new addition to the list is bell & hot peppers, which bump potatoes off the list.
  • Over 90% of strawberry, apple, cherry, spinach, nectarines, and leafy green samples tested positive for residues of two or more pesticides.
  • Multiple samples of kale, collard, and mustard greens contained as many as 20 different pesticide residues.

The 2021 Clean Fifteen

The following 15 fruits and veggies contained the least amount and lowest concentration of pesticide residues.

The Clean Fifteen List at a Glance:

  • The cleanest of all, for the fourth year in a row, is the healthy, fat-rich avocado! Fewer than 2% of avocado samples contained any detectable pesticide residues.
  • The rest of the Clean Fifteen list is largely the same as last year. The fruits and veggies on the list are the same, there were just a few position changes in the middle of the pack.

How Are the Dirty Dozen and Clean Fifteen Ranked?

The United States Department of Agriculture (USDA) and The Food and Drug Administration (FDA) test thousands of samples of produce sold in America. And the EWG analyzes the samples to determine which produce has the most pesticide residues (the Dirty Dozen) and which has the least pesticide residues (the Clean Fifteen.)

Then the EWG uses their findings to form the “Shoppers Guide to Pesticides in Produce.”

To compare pesticide contamination on each food, the EWG uses the following six measures:

  • The percent of samples tested with detectable pesticides.
  • The total number of pesticides found on the crop.
  • The percent of samples with two or more detectable pesticides.
  • The average number of pesticides found on a single sample.
  • The average amount of pesticides found, measured in parts per million.
  • The maximum number of pesticides found on a single sample.

If you’d like to delve a little further into clean and dirty produce, the EWG publishes a full version of their produce guide. It contains all 46 fruits and veggies involved in the pesticide tests. Check it out to see how produce like lettuce and bananas stack up against the Clean Fifteen and Dirty Dozen.

Does Organic Produce Contain Pesticides?

You might think that if produce is labeled as organic, it’s grown completely free of pesticides. But that isn’t quite the case.

The USDA states that “produce can be called organic if it’s certified to have grown on soil that had no prohibited substances applied for three years prior to harvest.”

Now, “prohibited substances” includes most synthetic pesticides. So it’s safe to say that organic produce will have far fewer potentially harmful synthetic pesticides compared to conventionally grown produce on average.

But it’s worth noting that organic growers can use certain synthetic substances on their crops. These are often exceptions to the general rule when there are no natural alternatives. You can see the full list of synthetic substances allowed for use in organic crop production here.

The main takeaway here? No matter if your fruit and veggies are conventionally grown or organic, you should wash them thoroughly! Keep reading to discover the most effective way…

How to Wash Your Fruits and Veggies

The produce in the Dirty Dozen and Clean Fifteen lists was peeled and rinsed in cold water before testing to mimic how people would prepare food for themselves at home. 

This shows that washing your produce doesn’t remove all pesticides. But the EWG states that unwashed produce will contain more pesticides than washed produce.

So, it’s important to wash your produce! While the Clean Fifteen boasts less pesticide residue than the Dirty Dozen list, you still need to wash your produce to ensure you’re consuming the least possible amount of dirt, dust, and pesticide residue.

But what’s the most effective way to wash your fruits and veggies? Here are a few tips from the FDA to help you out…


  • Wash fruit and veggies with soap or detergent
  • Use an abrasive brush on delicately skinned fruit


  1. Wash your hands with warm water and soap for 20 seconds before and after preparing fruit and veggies.
  2. Rinse your produce under running water before you peel or cut it, to prevent any bacteria transfer from the knife to the produce.
  3. Soak produce with ridges and crevices (like broccoli and cauliflower) for a few minutes longer.
  4. For produce with thick skin, use a gentle vegetable brush to help lift away additional pesticides and microbes.
  5. Dry your fruit and veggies when you’ve finished washing!

You may be thinking that commercial produce washes are missing from our Do list. But studies have shown that cold, distilled tap water is just as effective, if not more so, than costly veggie rinses.

Researchers at the University of Maine tested the following three commercial wash treatments:

  • J0-4 Multi-Functional Food Sterilizer
  • Fit®
  • Ozone Water Purifier XT-301

All three products were tested according to package directions. The researchers tested them on low-bush blueberries.

As well as the three commercial washes, a water wash was also tested. The blueberries were put in distilled water for one to two minutes.

Here are the results:

  • Fit® wash was able to get rid of the same amount of microbes as distilled water. Both reduced the level of pesticide residue compared to unwashed samples.
  • The J0-4 Multi-Functional Food Sterilizer and The Ozone Water Purifier XT-301 removed microbes from the blueberries. But the distilled water was more effective than both of the ozone washes.

Simple water for the win!

But why distilled water? Distilled water has been purified and filtered to remove contaminants. If you don’t have distilled water available, you can use cold tap water instead.

    I scrubbed apples in soapy water, but will do the distilled water for all from now on. Makes sense since distilled water is known to absorb/assimilate toxins and good for many purposes.

    Hi Nathan,
    Thanks for taking the time to comment! Yeah, I used to use a bit of vinegar (cut with water) but found it still left a bit of a taste, which I didn’t love.

    Hi Penny,
    I believe reverse osmosis water would do the trick as well, although I’m not too familiar with it.

    On their product’s package, Arm & Hammer suggests to use their baking soda as a cleaner for fruits & vegetables, either by manually washing or by soaking. It claims it removes debris & wax. Is this a safe solution? Afterall, baking soda is ingestible.

  10. Monica

    June 20, 2017 , 8:40 am

    Hi Wanda,
    I’ve heard of using baking soda to wash fruits and veggies, although I haven’t done it myself. If it’s recommended as a use of Arm & Hammer, then it should be safe.

    do you still need to wash apples if you peel them and any other peelable fruit?

  17. Monica AlgaeCal

    April 15, 2018 , 12:59 am

    That’s a great question, Doris. I searched EWG to try and find an answer and unfortunately came up short – I couldn’t find anything definitive for you.

    Personally, I still wash everything with a ‘thinner’ peel like kiwis and apples even if they are eventually going to be peeled because pesticides and residue may get transferred to the inside when peeled. But bananas and avocados I don’t. This isn’t the science-backed answer you were looking for, but I hope it helps in any case. I’ll follow up with a reply if I ever do come across this information though!

    Foodrevolution.org tested salt, vinegar and baking soda . Baking soda removed the most pesticides. I buy it in bulk, very cheap.

  21. Beth

    April 14, 2018 , 5:15 pm

    I find it rather incredible that soaking in distilled water alone would remove pesticides. Are pesticides removed from produce when it rains? I clean my produce with a mixture of water, vinegar, grapefruit seed extract with baking soda added to the moistened produce (I learned on the Oprah show years ago). Thank you for this article.

  22. Monica AlgaeCal

    April 15, 2018 , 12:38 am

    Hi Beth,

    That mixture sounds really great, I’ll have to try it! Right now I am using a produce brush in addition to distilled water when I’m washing my produce and am liking it.

    Baking soda cancels out the vinegar when used together so the mixture won’t work.

  25. Stacy

    April 14, 2018 , 7:30 pm

    Distilled water works great because it is acidic and has no after taste like vinegar.

  26. Monica AlgaeCal

    April 15, 2018 , 12:43 am

    Hi Stacy,

    Agreed! I always found my produce had a vinegar aftertaste with the natural washes that use vinegar. It wasn’t until I switched to distilled water and a gentle produce brush that I found, personally my favorite way, to wash my produce.

  27. Clara

    I’m still trying to understand why no soap if it’s a natural soap without all the chemicals, like Bronner’s.

  28. Monica AlgaeCal

    April 15, 2018 , 12:45 am

    Hi Clara,

    If you still prefer to use a natural soap to wash your produce, please continue to do so! This is just one study comparing the effects of commercial produce washes and water. It did find that distilled water was just as, if not more effective, but that doesn’t mean you have to use distilled water. We are just providing you with some information so you can make an informed decision.

    I greatly appreciate this information and the handy printables. My brain doesn’t hold onto things like it used to, and this is going on my fridge! We can’t afford organic much of the time. I sadly just quit eating strawberries. But fortunately organic apples are doable. If you have an Aldi, they are always a good price there.

    Thanks for the valuable information. So I am wondering though what about fruits and vegetables that you get from a stand like Untiedt–there fruits and vegetables are so good but am wondering if they would have pesticides also. Thanks for the info.

  32. Jenna AlgaeCal

    August 20, 2018 , 3:57 pm

    Good question, Sherry.

    In that case, it’s best to speak with the stand attendant to determine the farms growing practices – as they may or may not use pesticides! And always be sure to wash your fruits and veggies using the guidelines above 🙂

    Thank you for sharing this valuable info! I have the lists posted for our patients in the office that I work in. As a nurse, one thing that came to mind as I read the article is that it would be important to remind people to thoroughly clean and rinse their kitchen sinks before filling them and and soaking produce, as sinks are generally one of the dirtiest, most bacteria-laden places in our homes. This is especially true if you’re soaking produce that will be eaten raw. Had to throw my two cents in!

  38. Nina Purcell

    Is it okay to eat apples, for instance, if you take off the skin?

  39. Jenna AlgaeCal

    November 12, 2018 , 3:25 pm

    Hi Nina,

    Apples have consistently topped the EWG’s Dirty Dozen list and contain an average of 4.4 pesticide residues. So while removing the skin will eliminate some pesticides, it may not effectively remove them all (some pesticides can penetrate the skin of the fruit).

    To be safe, it’s best to purchase organic apples whenever possible!

    – Jenna @ AlgaeCal

  40. Julia Holland

    September 8, 2019 , 1:28 pm

    Are the organic berries & apples pesticide free? I thought it said they tested them also.

  41. Megan AlgaeCal

    September 11, 2019 , 7:51 am

    Good question, Julia!

    Organic produce may still contain pesticides, but natural pesticides rather than synthetic ones. 🙂 Hope this helps!

    -Megan @ AlgaeCal

  42. Kris Charbs

    June 23, 2019 , 9:11 pm

    The skin of the apple is where a ton of the nutrition is, so removing the skin is really not the best idea. You’ll find this to be true with lots of fruits and vegetables. Think of all the skins you already eat! I scrub carrots but don’t peel them. The white part of an orange (the pith) has more vitamin C than the actual orange does, so eat up! The green leaves on a strawberry are similar to eating any greens. So if you’re making a smoothie, leave the leaves!

    February 6, 2019 , 6:28 am

    Thanks. But I would want much better data on AMOUNT of pesticide removal by alternate washing methods. Farmers don’t want expensive pesticides to wash away in rain, so they’re oil-based rather than water-based. A few drops of dish detergent (like Dawn) plus rinsing, in ten seconds will remove MUCH pesticide, whereas just cold water will remove ALMOST NONE!

  46. Joani

    April 8, 2019 , 6:40 pm

    Dawn is toxic! I don’t even use it to wash dishes! I use vinegar and water. I soak fruit or veggies for a few minutes. The dirt in the bottom of the bowl is shocking, but my grapes sure are squeaky clean!

  47. Bill Mengers

    April 11, 2020 , 11:16 pm

    I agree with Jim above about test data from different cleaning methods, including test data on any residue left after using dish soap, which I have always wondered about, but generally thought did not leave a residue if rinsed well, especially with hot water. I know it says above not to use soap and water, but it doesn’t mention test data. If pesticides are mixed with oils (?), Soap works well in dissolving grease and oil.

  48. Audrwy

    This is excellent information. Thank you! So how do you pre wash raspberries and leafy greens without them getting mushy in the fridge? And do you store them in containers?

  49. Jenna AlgaeCal

    February 12, 2019 , 3:01 pm

    Oh good question, Audrwy! I find it helps to pat dry soft fruits and leafy greens then store them in a container lined with paper towel (with berries I reuse the original container).

    When I buy (organic) boxed salad mix I always shake the container every time I pull out the greens. When the greens are smashed together in the box they are wet and deteriorate faster. I find that by shaking the box the greens pull away from each, and they keep longer.

    Thanks for the info. I always wash my fruits and veggies with water & vinegar. Even in some of the ready to be eaten pack pre-cut veggies, I still wash them to be sure. You can tell the difference if it is organic or non-organic fruit if you always eat it. The info is very helpful.

  54. Lou

    March 31, 2019 , 4:36 pm

    The vinegar mixture sounds like it would clean better than water. However, what would kill the OTHER gross things on the veggies–for instance, human waste? I clean my veggies with soap and water because I am afraid of these other germs. Does the vinegar kill these germs, too?

  55. Sissybugs

    April 13, 2019 , 7:48 pm

    Yes, the acid in the vinegar basically kills anything bad. I do a clean rinse after.

    This is good info! And who knew it was such a hot topic? 🙂 I’m glad to know I don’t have to spend money on useless cleaning products. I have used vinegar in the water myself and done a rinse after. The baking soda sounds like an interesting one to try. The point is using science to break down the pesticide residue chemically so it is removed. (Man speak) Distilled water, or just water at a cold temperature, has the right state to break down the residue. Throwing gas on it won’t work.

  58. Janet

    May 5, 2019 , 9:02 am

    I’ve never done anything more than a quick rinse under running water, after buying organic, unless it’s from our garden and has aphids, then it gets soaked in salted water. Sometimes I pack greens in plastic bags or clamshells lined with paper towels, but I hear paper towels aren’t the healthiest thing to be nestled next to our produce either. We do our best and then we pray over our food and leave the rest to God.

    One thing to be aware of is that baking soda (Arm & Hammer seems to be the most popular) contains ALUMINUM! In order to avoid this toxin, you would have to purchase baking soda in a Health Food Store where they sell brands that do not add aluminum. Of course this is more expensive but our health is definitely worth it!

    A garden of your own is a great option. Growing up there was always a garden and canning for the winter. I live in a condo now with no ground space. Community gardens are not available where I live. Do I have any options?

    Hi Neila,

    That’s a good question. Believe it or not, there are ways to grow a small garden inside your condo! You might find this link helpful.

    Happy gardening! 🙂

    You can try bag gardening, especially if you have a patio or balcony. I’ve used recyclable bags bought from grocers, & had g’luck with tomato and potatoes I also use vinegar sprays and/or rubbing alcohol as pesticides You can google any of that to see if any are good for you G’luck! Have fun and enjoy your fruits!

    Is iit safe to eat boxed organic spring mix and spinach without rinsing or cleaning the produce? If not how would you clean boxed organic fresh spinach?

    Hi Susan!

    While these often come pre-washed, some individuals choose to give these a rinse again before eating. This is up to your personal preference. If you do want to give these another rinse, you can do so in a colander and dry them off with towels or a salad spinner.

    Hope this helps!

    If it is organic, wont washing remove the surface probiotics?

    Hi Nadine,

    Great question! Not to worry, washing your fruits/veggies won’t remove all of the good bacteria – and it will make them safer for you to eat ?

    For cleaning fruits and vegetables in a big bowl of tap water, how much vinegar do you use?

  94. Blaire AlgaeCal

    April 13, 2020 , 1:47 pm

    Hi Patty,

    That’s a great question! It’s recommended to use 1 part vinegar to 3 parts water ?

    I use distilled water from Waterwise 4000. I mix 3 parts distilled water to 1 part white vinegar. Wash and dry. Leaves no taste. Leave in water about 5 minutes.
    Something that packages I spray outside of package with 1/4 teaspoon Clorox to quart of distilled water. Use on cutting boards.

    I use no tap water in my area for cooking or drinking for 35 years.

    Even though bananas are on the clean list, I still buy organic because of the low life-expectancy of workers who spray the pesticides. These workers have little protective equipment to prevent long-term exposure. I know we can’t do *everything,* but we can do some things to create the kind of world we want to live in!

    So does this mean that I shouldn’t eat apples or strawberries if they aren’t organic or if I soak them for 15 minutes in distilled water will they be safe??

  102. Megan AlgaeCal

    May 13, 2020 , 2:08 pm

    Good question, Jeanne!

    We encourage you to buy organic when possible, but you can also put them in distilled water to remove some pesticide residue. A few minutes should do the trick! 🙂

    I know my neighbor would spray his Apple trees before there were apples and then quite often. So I would assume that the pesticide is not juston the skin of the apples, but rather through out.

    Any more useful than plain water?

    Yes, vinegar is a great way to clean your produce – as long as you don’t mind any potential aftertaste!

    As I understand it, vinegar is great for any dirt or bacteria, but baking soda works better on pesticides.

    I do not understand why washing fruit and vegies with dish soap is considered dangerous. We wash our dishes; then rinse off the dish soap and let them air dry. If that is considered safe, shouldn’t it be safe to wash our fruits and vegies with it?

  111. Blaire AlgaeCal

    May 14, 2020 , 9:26 am

    We hear you, Mickey! Monica responded to a similar comment and I will share her response with you below 🙂

    “If you still prefer to use a natural soap to wash your produce, please continue to do so! This is just one study comparing the effects of commercial produce washes and water. It did find that distilled water was just as, if not more effective, but that doesn’t mean you have to use distilled water. We are just providing you with some information so you can make an informed decision.”

    Hope that helps!

    If you must use soap, I would use pure hand soap like Ivory.

    Also, I have heard baking soda in water makes a great soak…

  113. steph

    September 29, 2021 , 1:54 pm

    my guess is that dishes are not porous – the dish soap stays on the surface of the dishes and doesn’t get into the dishes, it can be completely rinsed off. Although, certain things like pizza stones etc are porous and if you use soap, the soap can get into the stone and not completely wash out.
    I would imagine that fruits and veggies are possibly more porous than dishes, that is why I would use dish soap, but, I could be wrong, I would use lemon juice or vinegar which are sometimes used in natural cleaning products and they are edible.

    Very informative content. Fyi, there’s a typo on the b&w PDF under Dirty Dozen: “The fruits and veggies with the LEAST pesticide residues” should be MOST.

    How about a baking soda wash then a rinse with a little bit of citric acid added. the acid will help release any alkaline residuals plus shouldn’t have bad taste. also the acid is used in EPA reg. disinfectant products.

  117. Megan AlgaeCal

    October 13, 2020 , 9:49 am

    Hi Spencer, thanks for sharing!

    You may want to stick with either the baking soda or citric acid rather than combining the two. This article explains why.

    Hope this helps! 🙂

    Should you still purchase organic fruits and veggies from the 15 clean list?
    I try to always buy organic, but if the 15 clean list is OK to purchase it would be less expensive.

  119. Megan AlgaeCal

    November 10, 2020 , 3:24 pm

    Hi Sharon, good question!

    The decision is up to you. As noted in the Clean Fifteen List, almost 70% of these samples had no pesticide residues. If you’re looking to balance your budget, then focusing on the Dirty Dozen List can definitely help! ❤️

  121. Megan AlgaeCal

    January 25, 2021 , 2:17 pm

    Hi Lois, this is a great question!

    There are definitely benefits to purchasing as local as possible. It looks like the EWG has actually analyzed Wyman’s Wild Blueberries and has found that there’s low concern for food additives, pesticides, hormones, antibiotics, and contaminants. You can see this here.

    Looks like a great choice for blueberries 🙂 Hope this helps!

    For the last 5 -10 yrs I stopped using dish detergent except in situations like oils. Instead I use distilled white vinegar for household cleaning, including dishes. I use it to clean (organic) veggies like celery, carrots, avocado skin, etc. with light scrub & rinse. Never had any issues. Since it’s an acid I presume it also cleans & destroys any possible pesticide or residue and wondering if there are any studies or confirmation? Thank you for this article!

  127. Megan AlgaeCal

    August 4, 2021 , 9:21 am

    Hi Carol!

    Here’s a study showing that soaking in an acetic acid solution (the active ingredient in white vinegar) helped to reduce pesticide content, though salt water was effective as well. 🙂
