Please excuse me if i'm not up on the latest, but as of the last
National Cancer institute report, most cancer rates are decreasing.
The dyes under investigation have bbeen tested for use in human products
and found safe by the FDA. Checking things out with our local
biology people, the insect and human physiology are sufficiently
different that lots of things that kill the bugs don't show any effect
on humans.
