Special Surveillance Area (SSA)
If a free-ranging or privately-owned cervid (POC) tests positive for chronic wasting disease (CWD), then a buffer circle is created around that positive animal. This buffer circle is referred to as a Special Surveillance Area (SSA). POC facilities that fall within a SSA will have increased CWD testing requirements.
More specifically, if a free-ranging cervid is found to be positive for CWD, a 15-mile radius circle is created around the positive animal. And, if a POC is found to be positive for CWD, a 5-mile radius circle is created around the positive animal. Further, for both cases, the SSA extends to the entirety of the county of the infected animal and any county that the 15-mile or 5-mile circle touches.
For a complete list of counties that are included within a particular SSA, please review the map.
