Wild Boars
Wild hogs hurt the US economy by roughly $1.5 billion annually. Although it sounds terrible, it might not be as bad as the problem with wild boars that several regions of Asia and Europe are currently facing. Although there is significant harm, at least the wild pigs are not radioactive. A common meat source in the Czech Republic is wild boar. Unfortunately, the Chernobyl tragedy has resulted in the boars absorbing an increasing amount of radiation.
There was a significant amount of Caesium-137 discharged into the atmosphere during the meltdown at Chernobyl. That eventually dispersed into the soil of the Sumava highlands. Truffles eventually absorb the radiation, and boars go on the hunt for and consume the truffles. After residents in Japan left the region of the Fukushima nuclear meltdown, boars moved in and started breeding with domestic pigs that had escaped.
As a result, the region was effectively overrun by a large population of radioactive pigs and boars, making it challenging for people to move back. The meat is a delicacy, just like in Europe, but it's too unsafe to eat. Caesium-137 levels in some samples are 300 times greater than what is permitted by safety regulations.
