The Dirty Dozen and The Clean Fifteen

The Dirty Dozen and the Clean Fifteen are two lists of produce produced by the Environmental Working Group (EWG). They are taken from a list of 48 fruits and vegetables tested for pesticide residues and represent the dirtiest and cleanest fruits and vegetables respectively. The Dirty Dozen was originally a list of the dirtiest twelve fruits and vegetables, however EWG has included more than twelve in recent years. In 2013 zucchini/courgette/summer squash and kale were found to contain pesticides which are particularly toxic to the nervous system and it was deemed appropriate to include them.
