The Environmental Working Group (EWG) released its annual Shopper’s Guide today, including the latest iteration of its “Dirty Dozen” list – a ranking of produce most likely to be contaminated with pesticides.

The guide ranks 48 popular fruits and vegetables based on an analysis of 32,000 samples tested by U.S. Department of Agriculture and the U.S. Food and Drug Administration.

Topping the list of most contaminated was apples. As Food Safety News reported last week, EWG is asking that the U.S. Environmental Protection Agency investigate whether a pesticide commonly applied to conventionally grown apples but banned by the European Commission is safe for U.S. consumers.

The report also includes a list of the “cleanest” produce, featuring avocados at the top, with only 1 percent of samples tested showing any detectable pesticides.
