The "Dirty Dozen (12)" and "Clean 15" lists for 2019

Dirty Dozen 2019 AlgaeCalEvery year the Environmental Working Group ( publishes the Dirty Dozen, or list of the 12 most "contaminated" fruits and vegetables, and the list of the 15 most "innocent"ones, based on metrics in the USA market. Many of these pesticide problems arise because of the specific sensitivity of some products and some of the peculiarities of the US market, but the research gives some (partial) insight into the global scale..

It should be noted that, although the EWG publishes lists urging customers for purchasing organic products (see full study), things are not so simple as third-party surveys (eg Savage) note that in most products, residual levels of pesticides between organic and conventional products are not so much different. But it seems that everyone agrees that some product categories are more "guilty" than others (both for conventional and organic).

A useful note is that, following the pressure of the market and "fashion" trends, for the first time on the guilty list (and indeed in the 3rd position!!) appeared the "kale", which has the reputation of "superfood" - with some samples having up to 18 different residues!!!

Here's the full list of EWG's "Dirty Dozen" for 2019:

  1. Strawberries
