Answer:
Residues from various pesticides may be found on the skin of many fruits, including citrus fruits, but there are official regulatory efforts to keep the levels low in the American market and ways to remove most of the chemicals before the fruit is consumed, said Lambert H. B. Kanga, professor of entomology at Florida A&M University in Tallahassee.
The concentration of residues depends on the class of pesticide and frequency of applications, Dr. Kanga said, and several federal agencies work to protect consumers by setting tolerance limits and regulating use and exposure.
