Keep in mind that there have been residue standards for a long time now.
Prior to RR crops, the standards only had to account for glyphosate
residues from drift, rather than from direct applications. These same
crops however, also had residue tolerances for those herbicides actually
being used for their production.

However, there has been no scientific testing to determine the effect
of a 200 times increase in Roundup residue on human health...

There has been a very great deal of testing on Round Up for toxicity as
there has any pesticide. It the only one I know of that fish can live in a
concentration that will kill plants. They can't live very long because the
lack of plants and algae to clean the water of their waste causes the wastes
to build up to a toxic level.
