For the first time ever in Oregon, a fatal fungal disease has been found in bats.

The Oregon Department of Fish and Wildlife announced Wednesday afternoon that the disease known as white-nose syndrome has been detected in several bats across Columbia and Benton counties.

The disease is not dangerous to people.

White-nose syndrome kills bats by disrupting their hibernation, causing them to burn up vital fat reserves while searching for food. They often die from starvation or dehydration as a result.

According to ODFW, laboratory tests by the National Wildlife Health Center this month diagnosed the disease in seven small insectivorous bats. They were found dead in residential areas and reported to officials this winter.

Last year, officials announced they had detected the fungus that causes the disease in bat poop, or guano, at a roost in Clatsop County.

ODFW says it’s working with partners to learn more about potential impacts. The agency is also helping with monitoring and screening efforts.
