What a perfect case study. Make it mandatory to label food as being irradiated - results in food that's been irradiated being pretty unmarketable. Absolutely safe, but people see the big R word in there. "Oh noes! Three Mile Island! My food is radioactive. It's going to give me cancer!" And the idiots (80% who don't realize DNA is in food), don't buy safer food. Any idea how many illnesses and deaths would have been prevented by killing pathogens via irradiation? Hell, if half of these people had been around in the early 1900s, and if automobiles were forced to put a sticker on the gas tank, "warning, contains combustible fuels," we'd still be riding horse and wagons.
Ironically, what's bizarre about that attempt at humor, is that the combustible fuels in automobile have directly caused more deaths than irradiated food would ever be capable of causing in a millenia.
