The Dirty Dozen and Clean Fifteen⁚ A Guide to Pesticide Residues in Produce
The Environmental Working Group (EWG) annually publishes its Shoppers Guide to Pesticides in Produce, which includes the Dirty Dozen and Clean Fifteen lists. These lists are designed to help consumers make informed choices about which fruits and vegetables to buy organic and which are safe to buy conventionally.
Introduction
The Environmental Working Group (EWG) has been publishing its Shoppers Guide to Pesticides in Produce for over two decades. This guide helps consumers make informed decisions about which fruits and vegetables to buy organic and which are safe to buy conventionally. The guide features two lists⁚ the Dirty Dozen, which highlights the 12 produce items with the highest pesticide residues, and the Clean Fifteen, which lists the 15 produce items with the lowest pesticide residues.
What are the Dirty Dozen and Clean Fifteen?
The Dirty Dozen is a list of 12 fruits and vegetables that have the highest levels of pesticide residues, as determined by the Environmental Working Group (EWG). The Clean Fifteen is a list of 15 fruits and vegetables that have the lowest levels of pesticide residues. These lists are based on data from the U.S. Department of Agriculture (USDA) Pesticide Data Program (PDP). The EWG recommends buying organic produce from the Dirty Dozen list and buying conventional produce from the Clean Fifteen list.
