Regardless of whether you’re a parent, an environmentalist, or just a plain old shopper, chances are you’ve gazed out over the supermarket produce section and asked yourself, “Should I buy organic?”

Everyone’s heard of the scary chemicals used by agribusiness to keep your apples worm-free—it’s what generates the fear that makes organic produce lucrative. In exchange for more money, consumers are told they can have pesticide-free peace of mind. On Wednesday, the Environmental Working Group (which calls itself a nonpartisan organization aimed at protecting human health and the environment) released its annual ranking of the best (“Clean Fifteen”) and the worst (“Dirty Dozen”) produce when it comes to pesticide content. The list is meant to be a tool for the consumer: If your favorite fruit is among the Dirty Dozen, the thinking goes, you’d be safer buying organic.

Strawberries and spinach hold the top two spots in this year’s Dirty Dozen—more than 98 percent of samples tested positive for pesticide residue. One sample of strawberries, the report states, came with 20 different pesticides, while spinach samples had on average double the amount of pesticide residue by weight as any of the other crops reviewed.

When buying conventional, the guide says, try to stick with the Clean Fifteen: These fruits and vegetables, including sweet corn, mangoes, eggplant, and cabbage, had the fewest pesticides present and in the lowest concentrations. The guide also helps shoppers feel as if they are saving money safely: You don’t need to cough up extra cash for already expensive avocados, for example, because only 1 percent had detectable pesticide.
