It can be hard or impossible to afford or to find organic for all your fruits and vegetables. So it’s helpful to know how to prioritize. And fortunately there is a way, based on measurement of pesticide residues by the U.S. Department of Agriculture (USDA).
Some conventionally grown fruits and vegetables just naturally ‘take up’ and retain more pesticide residues. These foods that tend to retain high levels of pesticides are more important to buy organic. They have been dubbed the ‘Dirty Dozen’ (even though they now number 14).
