Roughly 95% of nonorganic strawberries, leafy greens resembling spinach and kale, collard and mustard greens, grapes, peaches and pears examined by america authorities contained detectable ranges of pesticides, in line with the 2024 Shopper’s Information to Pesticides in Produce.
Nectarines, apples, bell and sizzling peppers, cherries, blueberries and inexperienced beans rounded out the checklist of the 12 most contaminated samples of produce. It’s dubbed the “Soiled Dozen” by the Environmental Working Group, or EWG, an environmental and well being advocacy group that has produced the annual report since 2004.
Pesticides have been linked in research to preterm births, congenital malformations resembling neural tube defects, spontaneous abortions and a rise in genetic injury in people. Publicity to pesticides has additionally been related to decrease sperm concentrations, coronary heart illness, most cancers and different problems.
Farmworkers who use or are uncovered to pesticides are at highest danger, in line with research. A 2022 meta-analysis discovered employees uncovered to pesticides had been practically 5 occasions as more likely to have DNA injury whereas a February examine discovered youngsters uncovered at an early age confirmed poorer neurodevelopment from infancy to adolescence.
It’s not all dangerous information. Avocados, candy corn, pineapples, onions and papayas led the “Clear Fifteen” checklist of conventionally grown produce with the least quantity of hint pesticides — practically 65% of the fruits and veggies in that grouping had no detectable pesticide residues, in line with the report launched Wednesday.
Rounding out the “Clear Fifteen” had been frozen candy peas, asparagus, honeydew melons, kiwis, cabbage, watermelons, mushrooms, mangoes, candy potatoes and carrots.

Crops which develop near the bottom, resembling strawberries, spinach and different leafy greens are notably topic to pests.
Washed, peeled and scrubbed
Every year, a rotating checklist of home and imported produce is examined by US Division of Agriculture and US Meals and Drug Administration. Staffers on the USDA Pesticide Information Program wash, peel and scrub vegetables and fruit as customers would, whereas employees on the FDA solely brush dust off the produce. Then the vegetables and fruit are examined for greater than 250 totally different pesticides and the outcomes are posted on-line.
For 2024, EWG researchers examined testing information on 47,510 samples of 46 nonorganic vegetables and fruit, with nearly all of testing from the USDA. An evaluation of that information discovered traces of 254 pesticides in all vegetables and fruit analyzed, with 209 of these chemical substances on produce within the “Soiled Dozen” checklist.
“We discover that what finally ends up on one checklist versus the opposite displays how these vegetables and fruit are grown,” stated Alexis Temkin, EWG’s senior toxicologist. “Avocados, for instance, aren’t pesticide intensive, whereas strawberries develop very near the bottom and have quite a lot of pests.”
About 70% of nonorganic produce examined by the USDA and FDA have pesticide ranges throughout the authorized limits allowed by the US Environmental Safety Company, in line with the EWG report. That reality makes the report deceptive, stated Carl Winter, emeritus professor of cooperative extension on the College of California, Davis.
“The dose makes the poison, not its presence or its absence, and that dose determines the potential for hurt. In lots of circumstances you’d need to be uncovered to 1,000,000 occasions greater than what we’re uncovered to earlier than you’d even see any results,” stated Winter, talking on behalf of the Alliance on Meals and Farming, which represents natural and standard farmers.
Nonetheless, “authorized ranges don’t imply protected ranges,” Temkin stated in response. She pointed to occasions when regulators allowed probably harmful chemical substances, such because the pesticide DCPA, to stay in the marketplace lengthy after scientific analysis had raised considerations. The herbicide was linked to thyroid considerations for years earlier than the EPA advised the general public the chemical posed “important dangers to human well being” in 2023.
One other instance: chlorpyrifos, a pesticide linked to mind injury in youngsters and fetuses. The American Academy of Pediatrics joined EWG in 2017 protesting the EPA’s continued approval of the chemical.
As well as, pesticides banned by the federal government proceed to point out up on crops offered within the US, in line with the EWG report.
“Inexperienced beans for instance, proceed to point out traces of acephate, a poisonous pesticide the EPA banned to be used on inexperienced beans greater than 10 years in the past,” Temkin stated. “Loads of pesticides discovered on the ‘Soiled Dozen’ have additionally been banned within the European Union due to their dangerous results on human well being.”
One other concern from critics is that the “Soiled Dozen” checklist is insulting to multigenerational farmers who wrestle to develop meals for the nation and feed those self same merchandise to their very own youngsters, stated Steve Clement, CEO of Pacific Northwest Tree Fruit
“When this report comes out it’s like getting stabbed a little bit bit as a result of we’re working so arduous to place out a pleasant wholesome product, and the implication of the ‘Soiled Dozen’ checklist is that it’s unhealthy,” Clement stated. “It’s like doing one thing form for someone after which having them flip round and name you some form of monster.”
The report could scare individuals away from consuming the vegetables and fruit they want, stated Neil Nagata, whose household has grown natural and standard strawberries in Oceanside, California, for many years.
“Each time the report comes out, or there’s a scare on imported strawberries, we see our gross sales drop off,” Nagata stated. “It’s not as if we’re doing one thing that’s incorrect or incorrect, we’re truly producing very wholesome, protected meals. In actual fact, we truly stay within the strawberry discipline and my father is 100 and my mother is 97, and so they nonetheless eat strawberries.”

Some farmers really feel the time period “Soiled Dozen” is insulting, in line with the Alliance on Meals and Farming.
It is necessary that individuals eat a number of vegetables and fruit, even conventionally grown, stated EWG’s Temkin.
“We at all times emphasize that,” she stated. “We wish to allow customers who want to keep away from as many pesticides as attainable by choosing natural variations of the ‘Soiled Dozen,’ the place pesticide ranges will probably be decrease, after which, if they want, select inexpensive conventionally grown produce from the ‘Clear Fifteen.’”
Natural produce will not be extra nutritious, however research have discovered that ranges of pesticides within the urine of adults and kids can drop as much as 95% after a swap to an natural food plan.
For the primary time, EWG analysts checked out reported ranges of fungicides, one type of pesticide used to kill fungal ailments resembling powdery mildew.
“4 out of 5 of probably the most steadily discovered pesticides on the ‘Soiled Dozen’ checklist had been fungicides, and so they had been additionally present in notably excessive concentrations,” Temkin stated.
Two fungicides — fludioxonil and pyrimethanil — had the best focus on the “Soiled Dozen” checklist of another pesticide, in line with the report. Fludioxonil was discovered on 90% of peaches and practically 30% of all “Soiled Dozen” samples, in line with the report. Pyrimethanil was discovered on 65% of pear, 30% of apple, 27% of grape, 26% of strawberry and 24% of nectarine samples.
“Fungicides are sometimes utilized after harvest to maintain produce mold-free on its option to market. That’s doubtless why the concentrations had been so excessive on some samples – increased than different pesticides utilized earlier within the rising season,” Temkin stated. “The appliance of the fungicide can also be nearer to the time the produce is placed on retailer cabinets and customers are consuming them.”
Fludioxonil creates a waxy coating on the fruit or vegetable that research discover is troublesome to scrub away. Whereas the EPA finds fludioxonil protected at regulated ranges, some research have raised considerations that it’d disrupt hormone and neurological programs. Exposing breast most cancers cells to fludioxonil in a petri dish discovered the fungicide elevated cell manufacturing by 1.5%.
Pyrimethanil was categorized as a “attainable human carcinogen” by the EPA in 2004, however the company decided in 2015 the chemical was “not more likely to be carcinogenic to people” at low doses. Research have proven it to be poisonous to tree frogs and aquatic life, and it could disrupt thyroid ranges in pregnant ladies residing in agricultural areas. In lab assessments, pyrimethanil and fludioxonil had been present to influence androgen exercise — hormones that contribute to progress and replica in each women and men.
Cleansing vegetables and fruit earlier than consuming does scale back pesticide ranges, however “no washing technique is 100% efficient for eradicating all pesticide residues,” in line with the Nationwide Pesticide Info Heart.
Beginning with clear palms, wash and rub produce underneath working water as a substitute of soaking to take away probably the most pesticide, the middle recommends on its web site.
Don’t use cleaning soap, detergent or a business soak or scrub, nonetheless, as they haven’t been confirmed to be any more practical, in line with the FDA. Dry the produce with a clear material or paper towel to additional scale back micro organism which may be current.
