Fruits and vegetables may have residue of pesticide on the skin, but that does not make it harmful. As the products are harvested and move through many steps the pesticide residue is lessened. The remaining amount can be washed off and it will not cause harm. Fruits and vegetable with thin skin may be more affected, but as it is washed and cooked it will be safe to consume.
The EPA regulates and tests pesticides for safety before they are released to the market.
