acid herbicides in dried fruit

Pesticides are used in conventional farming to protect  plants. Usually there should not be any residues above the legal limits if these substances are applied correctly.  But many people demand a higher quality than the law requires. There is a fear of multi residues because no effective means to objectively  test the interaction between the different substances has been developed until now. Many find this frightening. And of course there should  be almost no residues in organic food.
