Pesticide Residue Monitoring Program

Back to Food Safety Info & Links
Back to Pesticide Use Enforcement

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 formats for data - compressed (zipped) and an Excel spreadsheet. Earlier residue files are compressed into self-extracting executable files. Please note: These files extract as tab-delimited text and should be viewed with a spreadsheet program (i.e., Excel, Lotus).


  • 2012 (executable, 928 kb) (Excel, 2.7 mb)
  • 2011 (executable, 457 kb) (Excel, 2 mb)
  • 2010 (executable, 518 kb) (Excel, 2.4 mb)
