For the third year in a row, strawberries take the top spot as the fruit that has the most residual pesticides on them.
The annual "Dirty Dozen" list from the Environmental Working Group reports a third of all strawberries had at least ten pesticide residues on them. And in one case, twenty-two pesticide residues were found on a single sample.
The study also features the "Clean Fifteen" -- fruits and vegetables with the least amount of pesticides on them.
Avocados take the top spot, followed by sweet corn, with fewer than one percent of the samples testing positive for pesticides.
Pineapples, cabbages, and onions also ranking high on the clean list.
This annual ranking doesn't have the support of everyone.
The Alliance for Food and Farming, which represents organic and non-organic farmers, calls the list "unsupportable."
And the U.S. Environmental Protection Agency says today's fruits and veggies are safer than ever.
The Environmental Working Group says the levels of residue the Environmental Protection Agency allows on produce can be harmful..
Experts recommend rinsing all fresh produce under tap water for at least thirty seconds before using.
