LINCOLN, Neb. (AP) — Authorities say livestock have been quarantined on two north-central Nebraska farms following diagnoses of a disease that can hamper an animal’s ability to eat and drink.

The Nebraska Agriculture Department said in a news release Monday that a U.S. Department of Agriculture laboratory confirmed the diagnoses of vesicular stomatitis. The samples were taken from infected cattle on two farms in Wheeler County. The USDA says other outbreaks this year have been confirmed in Colorado and Texas.

The virus that causes vesicular stomatitis is spread by insects and from animal to animal through open sores and saliva. The virus causes oral blisters and sores that can be painful.
