The U.S. Department of Agriculture published the 2017 "Pesticide Data Program (PDP) Annual Summary." The summary shows more than 99% of the samples tested had pesticide residues well below benchmark levels established by the Environmental Protection Agency.

Each year, USDA and EPA work together to identify foods to be tested on a rotating basis. In 2017, tests were conducted on fresh and processed foods, including fruits and vegetables as well as honey, milk and bottled water. USDA's Agricultural Marketing Service partners with cooperating state agencies to collect and analyze pesticide residue levels on selected foods. For more than 25 years, USDA has tested a variety of commodities, including fresh and processed fruits and vegetables, dairy, meat, poultry, grains, fish, rice, specialty products and water.

USDA tests a wide variety of domestic and imported foods, with a strong focus on foods that are consumed by infants and children. EPA relies on PDP data to conduct dietary risk assessments and to ensure that any pesticide residues in foods remain at levels that EPA has determined to be safe. USDA uses the data to help U.S. farmers improve agricultural practices and to enhance the department’s Integrated Pest Management Program.

The annual pesticide residue results are reported to the Food & Drug Administration and EPA in monthly reports as testing takes place throughout the year. FDA and EPA are immediately notified if a PDP test discovers residue levels that could pose a public safety risk.
