These Two Vegetables Are Very Toxic, According to New Research
The Environmental Working Group (EWG) has published a new report for the 2017 shopping season that rates produce on the amount of pesticides they are likely to contain. For the second straight year, strawberries have surpassed apples taking first place on the list, which has become an immensely popular resource to determine where best to spend your organic dollars. But read between the lines and you’ll find that there are two “highly toxic” (non-organic) vegetables to be aware of that didn’t make the EWG’s ‘Dirty Dozen’ list this time around.
When the U.S. Department of Agriculture (USDA) tested 35,200 different produce samples they found that pesticide residues still remain on many samples even after thorough washing, with several different types represented including the “probable human carcinogen” glyphosate, the main component of Monsanto’s Roundup weedkiller.
The key findings of this report included:
- Spinach jumped to second place on the list
- 178 different pesticides and pesticide breakdown products were discovered in total
- The most contaminated sample of strawberries had 20 different pesticide residues altogether
- Spinach samples had an average of roughly twice as much pesticide residue by weight than any other crop
As if that wasn’t bad enough, considering how popular these foods are, there are two other vegetables that actually contain two different highly toxic insecticides not found in any other produce — and they could be a part of your next salad.
Special warning about leafy greens and hot peppers: “Extraordinary Toxicity”
Leafy greens (kale and collard greens) and hot peppers, although not in the “dirty dozen,” may contain “trace levels of highly hazardous pesticides” that are highly toxic to the human body.
The pesticides that are especially concerning are insecticides: organophosphate, and carbamate. Because of legalities and voluntary opt-outs they are not found on other produce.
Hot peppers tested high in acephate, chlorpyrifos, and oxamyl in 2010-2011. They are banned to use on other crops, but allowed on hot peppers.
Strawberries are cheap and plentiful in the United States, but at what cost?
Acephate is a possible carcinogen, and is a reproductive health hazard. Chlorpyrifos is a neurotoxin. Oxamyl can lead to kidney and liver damage.
Collard greens have previously tested high in chlorpyrifos, famoxadone, oxydemeton, dieldrin, DDE and esfenvalerate in 2007-2008. Chlorpyrifos and esfenvalerate are not used on other crops, but allowed on greens. DDE and dieldrin are now banned, but still end up in leafy greens from the residues found in the soil.
Famoxadone has been linked to kidney and liver damage; oxydemeton is toxic to the reproductive system; dieldrin increases the risk of multiple myeloma; DDE is associated with aneuploidy (chromosome mutation); and esfenvalerate is a neurotoxin.
Because of the high toxicity of these pesticides, it is recommended to buy leafy greens and hot peppers organic, and if not possible to reduce the pesticide content by cooking these vegetables.
Here is the EWG’s updated ‘Dirty dozen” that is better purchased organic:
- Sweet Bell Peppers
Hot peppers come in at #13 because of the aforementioned concerns, although they technically are not part of the Dirty Dozen in 2017 they are in a special “Dirty Dozen Plus” category.

And here is the updated ‘Clean Fifteen’ list for this year:
The Clean Fifteen is the list of the vegetables with the lowest pesticide count, however, they still contain them at low amounts.
- Sweetcorn (buy organic if you want to guarantee it won’t be GMO; small amounts sold in the U.S. may be)
- Sweet peas (frozen)
- Papayas (some may be GMO; buy organic to avoid for certain)
- Honeydew Melon
