RICHMOND, Va. (AP) -- Virginia is limiting the movement of deer bagged in Pennsylvania into the state because of the detection of chronic wasting disease in the northern state.

The prohibition involves the transportation of whole carcasses of deer killed in Pennsylvania. Only portions of the dressed animal are allowed in the state. These include boned meat that is cut and wrapped, quarters or other portions of meat with no part of the spinal column or head attached, and antlers with no meat or tissue attached.

Chronic wasting disease affects the brains and nervous systems of deer and elk. There is no evidence to suggest that it poses a risk to humans or domestic animals.

The disease has been detected in 22 states, including Virginia and West Virginia.
