The kanji of this year

The kanji of this year was decided on "a false". Many cases happened this year. In particular, I was surprised at a camouflage case of the food in particular. In Hokkaido "SIROIKOIBITO", There was "AKAHUKU" elsewhere. Why does such a case happen? I think that consciousness for the appetite deteriorates. There is the person becoming afraid of that eat this case. Does the day when such a case disappears come?
