Mother Earth News has such great articles. Issue #277 Aug/sept 2016 has one (pg13+) titled “Pesticides on Produce: The New ‘Dirty Dozen’ summarizing the Environmental Working Group’s annual analysis of 48 fruits and vegetables for pesticide residues. Click here for the EWG site and report.

Top 12 dirty: strawberries, apples, nectarines, peaches, celery, grapes, cherries, spinach, tomatoes, sweet bell peppers, cherry tomatoes and cucumbers.

Clean fruits and vegetables lead off with the popular avocado. Now the problem with this fruit is that other countries are cutting rainforest to plant them, so check out where they are coming from. Then sweet corn  which really surprised me because it is GMO, by and large, and uses a ton of chemicals. I guess the residue level is low. I would still strongly suggest organic for corn. Then frozen sweet peas, cantaloupe and others less eaten by our dogs and cats.
