Fallout doesn't respect human borders. To this day, if you're out hunting game or collecting shrooms in Bavaria, you're well advised to test them for Chernobyl fallout, and required to do so if you're selling it [1]. At the start of last year, that made the headlines in regional papers as a hunter brought in a wild pig that was twice over the radiation limit [2].

The biggest problem are the shrooms because they actively seek out and concentrate radioactive elements in the ground for whatever reason, and then the wildlife eats the contaminated shrooms, further concentrating the radioactivity.
