EPA sets limits on how much of a pesticide may be used on food during growing and processing, and how much can remain on the food you buy. Public inquiries regarding EPA should be mailed to U.S. Environmental Protection Agency, Office of Pesticide Programs Public Docket (7506C), 3404, 401M St., Washington, DC 20460; telephone (202) 260-2080.
