Pesticide residue data on raw and processed food were obtained on a voluntary basis from agencies and organizations not required to submit these data to the Office of Pesticide Programs. The project was part of a scoping exercise to compile and summarize in an electronic format available monitoring data from outside EPA and to begin to evaluate the usefulness of these data for scientific and regulatory purposes. Data for 329 pesticides on over 61,000 samples were obtained from three primary sources: Agriculture Canada, state monitoring data compiled by FDA, and the National Food Processors Association.
