   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.
