They aren't tested, because previous testing showed it is no problem. Not even in Bavaria all boar is tested, only certain rwgions. Even there so, one couod make the case of not testing and just disposing hunted boar as it almost completely unsave to eat (above regulated thresholds).

The fallout landed in very random patches depending on weather literally at the time of the catastrophe. It is not really a function of distance alone.

My understanding is, some areas of Germany got more of the pollutants than say average for Poland.
