A to Z’s Dirty Baker’s Dozen

While local or organic produce is best, it’s not always available. As a rule of thumb choose organic thinner skinned and porous fruits and vegetables (nectarines, peaches and pears; strawberries, raspberries and other berries) as conventional varieties are high in pesticide residue. Our list is adapted from the Environmental Working Group’s annual “dirty dozen” and “clean 15”. We’ve also added corn to our “Organic Must Have’s list” because conventional U.S. corn is almost always genetically modified (GMO).

Dirty Thirteen   (% Sampled Contaminated with Pesticides)
Nectarines (97.3%)
Celery (94.5%)
Pears (94.4%)
Peaches (93.7%)
Apples (91%)

Strawberries  (90%)
Imported Grapes  (86%)
Spinach (83.4%)
Potatoes   (79.3%)

Red Raspberries  (59%)
