Six years after the Fukushima Daichi nuclear disaster — a major nuclear meltdown brought on by an earthquake and tsunami hitting Fukushima, Japan — some residents who fled the area are getting the go-ahead to finally return home.
The government has cleared four towns in the Fukushima prefecture as being safe for people, but there’s at least one issue standing in the way: Thousands of radioactive wild boars.
The boars, which have been consuming contaminated plants and smaller animals since the nuclear disaster, exhibit levels of the radioactive element cesium-137 that’s 300 times more than would be deemed safe for humans to consume, The New York Times reports.
The presence of the boars, which have thrived in the region since humans cleared out, isn’t news. The Washington Post reported last year on the animals, noting that scientists have found no evidence that the boars have any ill effects from radioactivity in their systems.
