“This is the fourth year where we’ve had apples on the top of the Dirty Dozen list,” Lunder said. “Meaning they have the most pesticides and the highest concentrations on them.”
The U.S.-based Environmental Working Group has released its “Dirty Dozen” and “Clean 15″ lists for 2014, detailing which fruits and vegetables have the most – and least – pesticide residue.
The EWG is a non-profit organization that acts as a public health and environmental watchdog, monitoring consumer products, food and environmental practices.
This year’s Dirty Dozen list includes apples, strawberries, grapes and celery — produce that is often eaten unpeeled. While the Clean 15 singles out avocado, sweet corn, pineapple, cabbage and others that often have a protective outer layer.
This year the EWG added an extra category — the Dirty Dozen Plus — to include kale and collard greens. The vegetables don’t meet the group’s traditional ranking criteria, but were still found to have residues of pesticides it considers toxic.
