Here’s a not-so-fun fact you need to know: Even if you rinse, scrub, and peel your fruits and veggies, harmful—sometimes even brain-damaging—pesticides often remain.
That’s because many weed- and bug-killing chemicals on the market are systemic, meaning they are taken up inside of the food you eat. In fact, Roundup, a weedkiller popular for use on crops and American lawns, in playgrounds, and in parks has been detected in everything from SunChips and ICU feeding-tube formula to Froot Loops and breast milk.
Clearly, our food system has gotten out of control.
A new analysis from Environmental Working Group (EWG) found nearly two-thirds of the more than 3,000 produce samples tested by the U.S. Department of Agriculture (USDA) in 2013 contained pesticide residues—no wonder more and more people are making organic food a priority.
In fact, USDA economists reported that organic produce sales spiked from $5.4 billion in 2005 to an estimated $15 billion last year and climbed 11 percent between 2013 and 2014.
Some highlights from EWG’s Shopper’s Guide to Pesticides in Produce:
- USDA tests found a total 165 different pesticides on thousands of fruit and vegetables samples examined in 2013.
- A single grape sample tested positive for 15 different pesticides.
- Nonorganic apples tended to have the most pesticide residues because they are chemically treated before and after harvest to preserve the fruit longer.
- The average potato had more pesticides by weight than any other type of produce.
To be clear, this shouldn’t scare you away from eating fruits and veggies—in fact, proposed new government eating guidelines suggest you should opt for a more plant-based diet.
The “Dirty Dozen Plus” and “Clean 15” lists (see below) are meant to encourage people to source fewer chemically treated foods. (And hopefully, persuade more farmers to opt for organic growing methods.)
It is important to note, though, that choosing organic as often as possible is your best defense against harmful chemicals. The powerful side effect of choosing organic is you’re also protecting farmworkers and their families from toxic chemical exposure. Foods on the “Clean 15” list often contain fewer different pesticides, but please don’t mistake that for pesticide-free. (And the sweet corn and papayas on the “Clean 15” list could in fact be GMO varieties unless you buy organic.)
“Dirty Dozen Plus” List
- Sweet Bell Peppers
- Cherry Tomatoes
- Snap Peas (Imported)
+ Leafy Greens
+ Hot Peppers
(EWG included + items because they routinely harbored particularly toxic insecticides shown to harm health.)
- Sweet Corn
- Sweet Peas (frozen)
- Sweet Potatoes
