The Environmental Working Group analyzed government data on 52 fruits and vegetables and found that 92 percent of apples contained two or more pesticides, even after they are washed and peeled.
The group believes more pesticides are being applied to apples after harvest to extend their shelf-life.
In addition to apples, the top five fruits and veggies most contaminated were celery, strawberries, peaches and spinach.
Consumers concerned about pesticides should consider buying organic produce.
