If you're wary of the promises of organic produce, maybe you should at the very least start eating organic strawberries, recent research suggests.
About a third of all strawberry samples had at least 10 pesticides, the study found. One sample, had an "astounding" 22 pesticide residues, notes the EWG, a non-profit group advocating for better human and environmental health.
Following strawberries on the Dirty Dozen list was spinach, in which 97% of samples contained pesticides residues. Rounding out the top five were three common fruits: nectarines, apples and grapes.
The report bases its findings on nearly 39,000 U.S. Department of Agriculture tests of 47 fruits and vegetables. It found nearly 70% of "conventionally grown produce" has pesticides and almost all — 98% — of strawberries, peaches, nectarines, cherries and apples contained at least one pesticide.
Meanwhile, the EWG's Clean Fifteen list features the produce "least likely to contain pesticide residues." Fewer than 1% of avocado and sweet corn samples featured pesticides, earning avocado the top spot on the list followed by sweet corn.
There was also good news for eaters of pineapples, papayas, asparagus, onions and cabbage. More than 80% of the time, these fruits and vegetables contained no pesticides, which can cause adverse health effects related to pregnancy complications and children with low IQs.
However, the U.S. Environmental Protection Agency says today's fruits and vegetables are "safer than ever." The Alliance for Food and Farming, which represents organic and non-organic growers, said the Dirty Dozen list is "unsupportable." It points to USDA and U.S. Food and Drug Administration data which shows 99% of residues are "well below safety levels" set by the Environmental Protection Agency.
The alliance's executive director Teresa Thorne said the list may deter low-income consumers from buying fruits and vegetables and "may be harming public health efforts to improve the diets of Americans."
