Gayle Orner at Oregon State University in Corvallis added the carcinogens dibenzopyrene (DBP) or aflatoxin to the feed of trout for one month, with or without the food dyes Red 40 - one of six recently linked to hyperactivity in children - or Blue 2.

Trout that had been fed DBP in combination with Red 40 had a 50 per cent lower incidence of stomach cancer and a 40 per cent lower incidence of liver cancer.  Read More...
