"The bottom line is people do not want to eat pesticides with their fruits and vegetables," said Ken Cook, EWG's president and cofounder. "That's why we will continue telling shoppers about agricultural chemicals that turn up on their produce, and we hope we will inform, and ultimately, empower them to eat cleaner."
The list also includes two additional produce items—leafy greens and hot peppers—since they are frequently contaminated with insecticides that are particularly toxic to human health, EWG notes.

Other Important Findings
• Nearly two-thirds of the 3,015 produce samples tested by the USDA in 2013 contained pesticide residues.
• Nonorganic apples tend to have the most pesticide residues because the chemicals are applied to the crop before and after harvest to preserve the fruit longer.

• 99 percent of apple samples, 98 percent of peaches, and 97 percent of nectarines tested positive for at least one pesticide residue.
• The average potato had more pesticides by weight than any other type of produce.
• A single grape sample and a sweet bell pepper sample contained 15 pesticides.
• Single samples of cherry tomatoes, nectarines, peaches, imported snap peas, and strawberries showed 13 different pesticides each.
"We are saying eat your fruits and vegetables," says Sonya Lunder, EWG's senior analyst. "But know which ones have the highest amounts of pesticides so you can opt for the organic versions, if available and affordable, or grab a snack off the Clean 15."
