Footnotes

1. Tests for any given food are often conducted in multiple years. In all cases WhatsOnMyFood shows only the most recent test year. The test results for Summer Squash come from test year 2008.

2. All pesticide residue results on this page and elsewhere on the WhatsOnMyFood website were obtained by the United Stated Department of Agriculture (USDA) Pesticide Data Program (PDP)

3. Punzi, JS, Lamont, M, Haynes, D, Epstein, RL, USDA Pesticide Data Program: Pesticide Residues on Fresh and Processed Fruit and Vegetables, Grains, Meats, Milk, and Drinking Water, Outlooks on Pesticide Management, June, 2005. Available online

4. All toxicological data was either compiled for this site — typically from U.S. EPA reregistration eligibility decisions — or obtained from data compiled for the PesticideInfo website

5. Includes pesticides that are moderately acutely toxic, highly acutely toxic or chronically toxic to honeybees.

6. The percentage found is for all four of the following combinations combined: domestic or imported, and conventional or organic. To see data broken down into each of these combinations separately, click on "Conventional vs. Organic."

7. A pesticide residue may not be listed as carcinogenic, neurotoxic, hormone-disrupting or as a reproductive or developmental toxicant for either of two reasons: (1) it may have been studied for toxicity in one or more of these categories and the weight of the evidence did not support designating it as toxic, or (2) it may not have been studied.
