(CNN) Would you like a bit of pesticide with your produce? While the chemicals farmers use on food keep produce relatively pest-free, the U.S. Department of Agriculture constantly runs tests to avoid too much pesticide residue on your plate. It concentrates particularly on produce items that children eat, since their developing bodies may be more vulnerable to harm from certain chemicals. Of the produce samples the USDA tested in 2014, the last year for which data is available, nearly three-fourths showed some kind of pesticide residue, which is about in keeping with other years. This amount persists despite growers' best efforts to clean up the produce, according to the Environmental Working Group, an environmental activist group. Annually, EWG puts together what it calls the "Dirty Dozen," a list of produce that has the most pesticide residue, according to the group's analysis of government data.Nearly three-fourths of tested produce showed some kind of pesticide residueStrawberries topped the list as having the most pesticide residue this year
