Wild boars roaming the Bavarian forests have become the focus of a scientific mystery: In some cases, they carry higher levels of radioactive contamination than wolves that live near the Chernobyl exclusion zone. Decades after the 1986 nuclear disaster, it was widely believed that the radiation problem was finally fading away. But these wild boars challenge that assumption. Despite living hundreds of miles from Chernobyl, their flesh often exceeds safe limits for radioactive cesium.

What’s the reason behind this surprising finding? The answer to this mystery is a complex combination of history, ecology and diet. Bavarian wild boars feed primarily on underground fungi that absorb radioactive fallout from the infamous Chernobyl disaster and Cold War-era nuclear weapons testing. Unlike wolves, which are higher on the food chain and have a diverse diet, wild boar naturally collect high concentrations of contaminants from what they eat. This article explores why Bavarian wild boars remain so highly radioactive, how their toxin levels compare to other wildlife in the region, and what it tells us about the long-term effects of nuclear radiation.

The contribution of nuclear testing during the Cold War

In a new study published by researchers at TU Austria and Leibniz University in Germany, scientists found that Cold War-era nuclear testing 60-80 years ago was a major contributor to the high radiation levels in Bavarian wild boar.

This was a groundbreaking revelation, given the government’s rhetoric at the time that the environmental impact of the nuclear testing program would be negligible.

wild boar sample

Researchers work with hunters in affected areas to obtain and examine samples of wild boar meat. As previously documented, wild boar samples contained extremely high levels of radioactive cesium-137 and cesium-135.

Next, the team set out to determine how much radiation was produced by nuclear tests in the area 60 to 80 years ago.

Radiation contamination of boars

To differentiate between sources of radiation, scientists use a mass spectrometer. This analytical tool helps determine whether radioactive cesium was produced through nuclear weapons explosive tests or the Chernobyl nuclear reactor.

Across all samples, they found that nuclear testing in the area caused 12-68% of the wild boar’s radioactive contamination.

Wild boar radiation: Why do their radiation levels remain so high?

But why are radiation levels so consistently high in Bavarian wild boar populations? While radioactivity levels in other game animals in the region have tended to decline over the years, levels in wild boar populations remain high.

In addition, radiation levels in topsoil in affected areas are also declining. Researchers describe the phenomenon of wild boars accumulating such high levels of cesium-137 and cesium-135 as the “wild boar paradox.”

While scientists have yet to come to a firm conclusion on this conundrum, many researchers believe the answer lies in the boar’s winter diet. During the colder months, wild boars rely heavily on eradicating truffles and other fungal fruiting bodies.

Some scientists speculate that over the years, radioactive material has made its way deep into the soil, where underground fungi absorbed the radiation. When wild boars consume this food each winter, they continue to pollute themselves.

About the Bavarian Wild Boars

wild boar, classified as wild boarnative to much of Eurasia, including Bavaria. They are one of the most wide-ranging mammals in the world and are extremely adaptable. The species is the ancestor of the American wild boar population, which was introduced for sport hunting in the early 1900s.

Wild boar populations are adaptable and cunning, quickly becoming destructive in many non-native environments. In their native ecosystems, healthy populations of natural predators such as big cats, bears and wolves keep wild boar populations in check.
