Each year, the non-profit consumer protection organization Environmental Working Group (EWG), releases its “Dirty Dozen” list. The list is intended to help you easily know which types of conventional grocery store produce have the most and least pesticide residues so you can make an informed buying decision.
EWG’s recently released 2018 Dirty Dozen list, from most to least pesticide contamination, is as follows:

How Does EWG Create Its Dirty Dozen List?
Are you wondering how EWG creates its Dirty Dozen list? Thankfully, their process is fully transparent and we highly encourage you to read how and why they create their annual list.
We’d also like to highlight a few important points:
1. Pesticides found at normal levels on conventional grocery store produce can negatively impact pregnancy outcomes.
EWG cites a new study published in JAMA Internal Medicine, a journal of the American Medical Association, which sought to find whether there is “an association between exposure to pesticide residues in fruits and vegetables and pregnancy outcomes.”
The study concluded that, “intake of high–pesticide residue fruits and vegetables was associated with a lower probability of live birth, while low–pesticide residue fruit and vegetable intake was not associated with this outcome.”
It’s important to note that the foods in this study were everyday conventional grocery produce – exactly the types of fruits & veggies that the average person (and pregnant woman) might eat each day.
2. Young children are at higher risk of pesticide exposure from food.
EWG doesn’t bring up this point, but small, rapidly developing infants and children are much more susceptible to pesticide exposure than adults. That’s why the American Academy of Pediatrics said the following in their official policy statement on pesticides:
- “Epidemiologic evidence demonstrates associations between early life exposure to pesticides and pediatric cancers, decreased cognitive function, and behavioral problems.”
- “For many children, diet may be the most influential source, as illustrated by an intervention study that placed children on an organic diet (produced without pesticide) and observed drastic and immediate decrease in urinary excretion of pesticide metabolites.”
You might have heard that organic farmers also use some pesticides, right? True, but on organic farms, only safe, NOP-approved pesticides are allowed, which go through rigorous testing to assure they pose virtually zero risk to farm workers, the environment, or people who eat organic food. That’s why synthetics like glyphosate (herbicide) and neonicotinoids (insecticide) are NOT used or allowed on organic farms even though they’re used on virtually every conventional farm.

Now, About Those Conventionally-Grown Strawberries In Your Shopping Cart…
If you want to lose your appetite and be a bit horrified, read the full summary of why strawberries are #1 on EWG’s Dirty Dozen list.
Just like there are unknown dangers in mixing prescription medications, there are unknown dangers in ingesting multiple types of synthetic pesticides, even in trace amounts.
Of the 1,174 batches of strawberries tested by USDA scientists, 99% had detectable levels of at least one pesticide. The dirtiest batches of strawberries sampled had “residues of 22 different pesticides and breakdown products.”
Overall, the strawberries sampled by the USDA contained residues of 81 different pesticides in various combinations, many of which are banned in Europe for safety concerns and have been “linked to cancer, reproductive and developmental damage, hormone disruption and neurological problems.” Yummy.
Growing The Dirty Dozen Right Here In California
Sadly, many of the produce varieties on the Dirty Dozen list are grown “dirty” right here in Cali.
Strawberries are a case in point, with over 75% of the fresh strawberries sold in the US grown right here in our state, many within a short trip from your house.
The EWG report documents that in California, “nearly 300 pounds of pesticides were applied to each acre of strawberries – an astonishing amount…”
Again, we encourage you to read EWG’s full report on strawberries, but we won’t write any more here for fear of ruining our appetites (it’s almost lunch time).
The Good News?
We don’t want to leave you with a sense of gloom & doom. Quite the contrary: we’ve got great news!
We work with a select network of local & organic farmers who are doing it right. This week, we even have local, fresh-picked organically grown strawberries, spinach, and peaches. Yep, all three of those are at the top of the Dirty Dozen list, but you can eat ours worry-free.
If you don’t live in San Diego County but you’re trying to figure out what to do with the information in this article, we’d like to leave you with two final concluding points:
- We’ve seen some industry groups criticize EWG and their Dirty Dozen list. It’s interesting to note that Consumer Reports, the most highly regarded non-profit consumer watchdog agency in the US, has also released a report and recommendations that mirror EWG’s findings. They also encourage people to eat organic foods whenever possible.
- If you’re pregnant or raising young children, please do try to avoid conventionally grown produce listed in EWG’s Dirty Dozen list. Even if you have to pay a bit more, it’s well worth it in the long run!
