Residue Monitoring Program

DPR samples individual lots of domestic and imported produce and analyzes them for pesticide residues to enforce the tolerances set by the U.S. Environmental Protection Agency. Samples are collected from throughout the channels of trade, including wholesale and retail outlets, distribution centers, and farmers markets. DPR Enforcement Branch staff collects the samples, and delivers them to a California Department of Food and Agriculture laboratory where all are tested with multiresidue screens capable of detecting more than 200 pesticides and breakdown products. In addition, selected samples receive specific analysis for nonscreenable pesticides of enforcement concern.

Annual Residue Data

Beginning in 2007, there are two data file choices - compressed and an actual spreadsheet. The remainder of the residue data files are compressed (zipped) into self-extracting executable files. To download click on the file name, in the "Save As" dialog box, select the drive and directory location where the file should be saved. It will extract as a text (tab delimited) file. Please Note: These files should be viewed by using a spreadsheet program (i.e., Excel, Lotus, etc.).
