The U.S. Department of Agriculture (USDA) has been conducting the Pesticide Data Program (PDP) since 1991. Since 1998 the PDP has measured pesticide residues on fresh fruits and vegetables, canned and frozen fruits and vegetables, fruit juices, whole milk, wheat, soybeans, oats, corn syrup, peanut butter, poultry, beef, pork, drinking water, bottled water, and groundwater. In order to maintain comparability across the years 1998 to 2009, the organophosphate detection rates reported in this indicator include only detections of the 43 organophosphate pesticides and metabolites that were included in the PDP for each and every year from 1998 to 2009 and were above the minimum of the limits of detection available in 1998.
