Why they're risky: To keep production up, farmers use pesticides on crops that are especially vulnerable to bugs, like peaches. The so-called "fragrant fruit" (yummy for pests) is also very thin skinned, which makes it easy for bugs and pesticides to enter. Farmers want to prevent diseases such as "leaf curl," which reduce the number of peaches they can harvest from their trees. An August 2009 Chicago Tribune investigation reported that USDA tests showed more than 50 pesticide compounds end up on domestic and imported peaches.
How to lower your exposure: If you love peaches, go organic—especially if you're pregnant or have a child under 6, says Riederer. Or for a sweet alternative with a similar texture, try domestically grown plums, which typically have less exposure to pesticides, according to the EWG.
