2022 Dirty Dozen and Clean Fifteen Lists

Updated: October 20, 2022

Organic Harvesting

The 12 Foods Most Likely To Carry Hidden Toxins

If you’re like me, you love getting lots of tasty fruits and vegetables in your diet. Unfortunately, more than 70 percent of the fresh produce sold in American grocery stores contains harmful toxins. And what’s even worse is some of these toxins have been classified as potentially carcinogenic.1
That’s according to researchers at the EWG(Environmental Working Group)2 Each year they release their Shopper’s Guide to Pesticides in Produce. The guide includes the Dirty Dozen™ and the Clean Fifteen™, two lists that analyze Department of Agriculture test data to identify which fruits and vegetables are most and least contaminated.


2022 Dirty DozenTM and Clean FifteenTM Lists

This year’s ‘dirtiest’ foods were strawberries, spinach, and kale. And yuk, they were really dirty! In one case, a single sample of kale was contaminated by 21 different pesticides,3 according to the report.  

But don’t let the Dirty DozenTM put you off your favorite fruits and veggies. “Fruits and vegetables are critical components of a healthy diet,” said toxicologist Thomas Galligan Ph.D. “We urge consumers who are concerned about their pesticide intake to consider, when possible, purchasing foods from the Clean FifteenTM list.
The Clean FifteenTM shows which fruits and veggies had the lowest concentrations of pesticide residues. And it’s good news for avocado lovers! That’s because 98 percent of avocado samples collected from grocery stores contained zero pesticides. In fact, almost 75 percent of the fruits and vegetables on this year’s Clean FifteenTM showed no detectable pesticide residue whatsoever.

EWG 2022 Dirty dozen

How are the Dirty DozenTM and Clean FifteenTM Ranked?

The United States Department of Agriculture (USDA) and the Food and Drug Administration (FDA) test thousands of samples of produce sold in American grocery stores. 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). 

To compare pesticide contamination on each food, the Environmental Working Group uses the following six measures. 

  • The percentage of samples tested with detectable pesticides
  • The total number of pesticides found on the sample
  • The percentage 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

But remember, the Clean FifteenTM only ranks fruits and vegetables based on pesticide residue. It doesn’t account for bacteria. Which builds up veryfast in busy grocery stores.4 Before avocados, bananas, and cherries end up in your basket – they’ve been squeezed, sniffed, and handled by dozens, maybe even hundreds, of other shoppers! So you’ll want to go ahead and give your produce a good wash when you get home from the store.

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. 

But what’s the most effective way to wash your fruits and veggies? Here’s a few tips5 from the FDA to help you out 

Wash your hands with warm water and soap for 20 seconds before and after prepping fruit and veggies Wash fruit and veggies with soap or detergent 

Rinse your produce under running water before you peel or cut it, to prevent any bacteria transfer from the knife to the produceUse an abrasive brush on delicarly skinned fruit
Soak produce with ridges and crevices (like broccoli and cauliflower) for a few minutes longer
For produce with thick skin, use a gentle vegetable brush to help lift away additional pesticides and
Dry your fruits and veggies after you’ve finished washing

And no, you don’t need to buy commercial produce washes. It’s not safe, since the skin of your favorite fruits and vegetables is likely to be porous.6 So just use cold water. 

Organic Produce

Organic is better

And if your favorite fruits and veggies are on the Dirty DozenTM list, don’t worry. Try to buy organically grown versions whenever you can. It’s a lot safer. That’s because organic farmers don’t use synthetic pesticides. “Several peer-reviewed studies have looked at what happens when people switch to a fully organic diet. And measurements of pesticides decrease very rapidly,” said Alexis Temkin Ph.D, a leading expert in toxic chemicals and pesticides.7,8   

So try switching to an organic diet. That’s the advice of bone health experts Lara and Joe Pizzorno. Not only is it better for your overall health, it’s better for your bones too! The pesticides found in conventionally grown foods often contain heavy metals like cadmium. And cadmium makes your bones weaker. It does this by displacing calcium and poisoning our osteoblasts. These are the cells which build healthy new bone. 

“The good news is that when you eat organically most of the toxins will leave the blood within four days.” Joe Pizzorno 

But organic food isn’t always accessible, or even affordable for a lot of people. That’s why it’s a great idea to grow your fruits and vegetables.


Grow Your Own Organic Food

In fact, starting an organic garden is doubly good for your bone health. With its bending, keeling, and gentle lifting, gardening stimulates your bones to become stronger. And what’s more, gardening gets you outside in the sunshine – and just 15 minutes of sunshine is enough to increase your body’s production of vitamin D. Which is essential for strong, healthy bones.

Plus, as any chef will tell you, you can’t beat the flavor of freshly picked produce from your own backyard!

    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.

    You’re recommending distilled water, what about reverse osmosis (RO) water?

    Would also appreciate a downloadable list option.

    March 23, 2017 , 9:09 am

    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.

  11. 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?

  18. 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.

  22. 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.

  23. 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.

  25. Carol

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

  26. Stacy

    April 14, 2018 , 7:30 pm

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

  27. 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.

  28. Clara

    April 14, 2018 , 8:12 pm

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

  29. 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.

  33. 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!

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

  40. 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

  41. Julia Holland

    September 8, 2019 , 1:28 pm

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

  42. 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

  43. 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!

  46. Jim Presant

    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!

  47. 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!

  48. 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.

  49. Audrwy

    February 9, 2019 , 5:50 am

    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?

  50. 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.

    March 4, 2019 , 5:20 pm

    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.

  55. 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?

  56. Sissybugs

    April 13, 2019 , 7:48 pm

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

  58. Laura

    April 2, 2019 , 7:50 am

    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.

  59. 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?

    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!

    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 ?

    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??

  103. 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.

    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?

  112. 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…

  114. 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.

  118. 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.

  120. 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! ❤️

    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!

  128. Megan AlgaeCal

    August 4, 2021 , 9:21 am

    Like your articles but find them not good for those of us that live in small rural communities. We would have to drive 75 miles each way to get to organic foods. With gas and the prices of organic foods this is not practical for us on social security. Do you have other advice for us?

  137. Chelsea Dugas

    July 29, 2022 , 8:12 am

    We totally understand that, Jane. The best recommendation we can provide is to make do with what you have, perhaps seek out local farmer’s markets in your area, order organic dried foods online, and if organic produce is completely unavailable to you, washing your produce in a vinegar or baking soda soak for 5-10 minutes can help to reduce the pesticide load. Hope this information helps!

    My grandmother was an immigrant from Italy and she washed everything before she cooked or peeled it. My mother does the same and so do I. This is nothing new to me. When I eat fruit I wash and peel the skin off before I eat it. You can only grow vegetables during the summer months in the Northeast. I buy AlgaeCal because it is safe but only my bone medication is building my bone destiny back. I get tired of the misinformation that you put out.

    Hi, Susan!

    There is a good chance that white potatoes are high among foods that have a heavy pesticide load, just not as high on the list as the 12 chosen. That said, it’s always wise to purchase organic as much as possible! Hope this helps! 🙂

    Thank you.

  152. Chelsea Dugas

    February 28, 2023 , 5:39 am

    Thanks for your questions, K! Yes, when mentioning pesticides, herbicides and fungicides are included. As per which pesticides are most prevalent, that would probably depend on the location the food was grown. Different countries use different pesticides predominantly (ex. Malathion and Glyphosate are most widely used in the US), so if your produce is imported from elsewhere, you would have to investigate a bit online to see what those countries use mostly. Hope this helps! 🙂
