Most pesticides advertise as being long lasting residual properties for killing bugs. Is this not a concern for human health and the rise in Cancer. Wouldn't washing vegis and fruit just take these poisons off the outside. What about the inside.

It is true that some pesticides are long lasting, but the vast majority of these pesticides are definitely not designed for use around crops, gardens, pets, children, etc. Most, if not all, pesticides for use on vegetables and fruits are designed not to penetrate the vegetable or fruit and to wash off relatively easily. Furthermore, these pesticides are designed to break down quickly on the plant and in the environment if used properly. Of course, the key phrase is "used properly." Pesticides must undergo approval by the Environmental Protection Agency before they are sold to the public. Tests must be performed to show that the pesticides are effective against the intended target and are not harmful to humans or the environment when used according the instructions on the container. In addition, the U.S. Department of Agriculture screens for pesticide residues before the product to ensure food safety.
