North Dakota and South Dakota on Tuesday joined the states placing restrictions on livestock imports from Texas after a case of vesicular stomatitis was found in a horse there, reports The Associated Press.

The viral disease, believed to be transmitted by insects, is not usually fatal, but state animal boards in the Dakotas said it can be costly for livestock owners. Infected animals suffer from blister-like lesions, generally refuse to eat or drink and show signs of lameness, resulting in severe weight loss.

"Using (restrictions) to screen animals reduces the chances of this costly disease establishing itself here," said Dr. Beth Carlson, North Dakota's deputy state veterinarian.
