Agricultural Chemicals: USDA Could Enhance Pesticide and Fertilizer Usage Data, Improve Outreach, and Better Leverage Resources

A letter report issued by the Government Accountability Office with an abstract that begins "The use of pesticides and fertilizers contributes to U.S. agricultural productivity and helps ensure a generally stable, plentiful, and inexpensive food supply. However, these chemicals may also harm human health, water quality, and food safety. The U.S. Department of Agriculture's (USDA) National Agricultural Statistics Service (NASS) collects, analyzes, and disseminates Agricultural Chemical Usage (ACU) data to meet regulatory, business, and other informational needs. In fiscal years 2007 through 2009, NASS substantially scaled back the ACU program before restoring it in 2010. GAO was asked to examine (1) what factors NASS considered in reducing the ACU program; (2) how ACU data users were affected by the temporary cutback, and their views on the data's quality and usefulness; and (3) the extent to which agricultural pesticide and fertilizer usage data are available from sources other than NASS. GAO reviewed relevant NASS documents and interviewed NASS officials as well as 25 selected ACU data users.
