Not mentioned is that organic farming doesn't allow irradiation which would kill e-coli. Everybody looks for organic foods thinking they are better but the truth is organic doesn't mean either.
In what way would irradiation make a food not-organic? I believe you, it seems stupid enough to be true.
I'd imagine many people are coming at it as something like "not produced or processed via industrial processes." And irradiation would probably be considered an industrial process.
