However, this report does not communicate the real risk. First, the levels found are well below anything that would pose an appreciable risk. Further, this ranking does not have any scientific basis. In a research article published in Journal of Toxicology (abstract below) by Winter and Katz (2011), they state:
In summary, findings conclusively demonstrate that consumer exposures to the ten most frequently detected pesticides on EWG’s “Dirty Dozen” commodity list are at negligible levels and that the EWG methodology is insufficient to allow any meaningful rankings among commodities. We concur with EWG President Kenneth Cook who maintains that “We recommend that people eat healthy by eating more fruits and vegetables, whether conventional or organic” [1], but our findings do not indicate that substituting organic forms of the “Dirty Dozen” commodities for conventional forms will lead to any measurable consumer health benefit.It is important that consumers include fruits and vegetables as part of their diet. They should not be deterred by headlines that would make them think otherwise.
Dirty Dozen: EWG Reveals List Of Pesticide-Heavy Fruits And Veggies

What could be purer than a single ingredient?
As health-minded consumers work to avoid processed meals and turn their focus to whole foods, we may find ourselves picking up fruits and veggies more often. The average American currently eats about 100 pounds of fresh produce per year, but that number could be a lot higher. While the U.S. Department of Agriculture recommends adults eat two to three daily servings of fruits and veggies, only one-third of us meet that recommendation.
Clearly, nothing should deter efforts to consume more fresh produce, the healthfulness of which is undeniable. But, as the latest iteration of an annual report reveals, there are some other considerations that health-conscious consumers must face from the supermarket aisle.
For the eighth year in a row, the nonprofit advocacy organization Environmental Working Group has released their list of the twelve most pesticide-laden fruits and vegetables on the market as part of their 2012 Shoppers Guide. Overall, they found that 68 percent of the food samples tested had detectable pesticide residues -- even after they had been washed or peeled. Many of the fruits and vegetables listed this year will look familiar to those who follow the yearly report -- apples and bell peppers once again top the list.
Certain pesticides have been identified as potential carcinogens, endocrine disruptors and have been associated with learning and developmental delays in children.
"Organophosphate pesticides are of special concern since they are associated with neurodevelopmental effects in children,” said EWG toxicologist Johanna Congleton in a statement. “Infants in particular should avoid exposure to these pesticides since they are more susceptible to the effects of chemical insult than adults."
Indeed, new research into the pesticide loads of baby food purees made with green beans, sweet potatoes and pears showed high contamination rates in both green beans and pears. Sweet potatoes, by contrast, had virtually no trace of pesticides.
To learn more about individual pesticides and health risks, check out the U.S. Centers for Disease Control and Prevention's report on human exposure.
To compile the rankings, EWG researchers looked at 45 popular fruits and vegetables based on pesticide-load reports conducted by the USDA and the Food and Drug Administration. The database includes 60,700 samples taken over a 10 year period, beginning in 2000. It's important to note that all of the testing is conducted on fruits and vegetables that have been washed and/or peeled -- the typical precautions taken by American consumers.
The researchers factor in how many of the samples test positively for detectable pesticides, how many have more than two discrete pesticides, the concentration (measured by parts per million) of the pesticides found and the highest number of pesticides found in any single sample. The researchers also looked at the total pesticide load of the fruit or vegetable crop as a whole.
And while the list is comprehensive, the ranking doesn't capture all information: For example, though apples were ranked as the most contaminated overall, imported nectarines had the unique distinction of having a full 100 percent rate of positive pesticide test results, above any other product. Bell peppers and grapes were both commonly contaminated with 15 different pesticides in a single sample -- the highest overall diversity of contamination.
Still, even the researchers who conducted the pesticide exposure studies don't recommend giving up the "Dirty Dozen" outright.
"The health benefits of a diet rich in fruits and vegetables outweigh [sic] the risks of pesticide exposure," they wrote, recommending instead that consumers purchase organic options wherever available and then choose items from the concurrent "Clean 15" list that details which fruits and veggies have the lowest pesticide loads and residues.
Lots of confusion when it comes to pesticides

Are you concerned about pesticides?
Sixty percent of consumers express a high concern about pesticide residues, much of which is based on misleading information, according to The Alliance for Food and Farming, a non-profit organization that represents organic and conventional farmers and farms of all sizes. Established in 1989, the Alliance’s goal is to deliver credible information to consumers about the safety of fruits and vegetables. Teresa Thorne, Alliance spokesperson, reported to us that recent surveys show that 29 percent of consumers are buying less fruits and vegetables due to concerns about pesticide residues.
The issue of pesticide residues can be very complex and terms often are used that are unfamiliar to many of us.
The Alliance’s website, safefruitsandveggies.com, is a chance for shoppers to explore science-based information about pesticide residues. The mere “presence” of a pesticide does not mean that the food is harmful, and to demonstrate this fact, the Alliance has provided a pesticide calculation tool, developed by Dr. Robert Krieger, toxicologist with the Personal Chemical Exposure Program at the University of California, Riverside, to see how many servings a man, woman, teen or child could consume and still not have any adverse effects from pesticide residues. Because of the complexity of the residue issue, the calculator was designed to be an easy way to show the very minute levels of pesticide residues that are found (when and if present at all).
