Pseudorabies virus was diagnosed in 14 of 16 feral hogs seized by Colorado state wildlife and agriculture officials in late November. According to Colorado animal-health officials, there was no exposure to commercial swine in the state.
The hogs were seized, along with 20 exotic sheep, in a trailer headed for Little Creek Ranch in Mesa County, Colo. The animals were diverted to a location with no access to wildlife or domestic swine and the ranch has now been quarantined. Further inspection of the ranch found several holes in the perimeter fencing meant to contain animals as well as other "regulatory deficiencies." Mesa County is located in western Colorado along the Utah-Colorado state line and the ranch is situated in the north-central part of the county.
The Little Creek Ranch, which has a wild-boar-hunting operation, is licensed by the state as a commercial wildlife park. The ranch existed prior to state regulations banning the importation or possession of wild boar and feral hogs. It was "grandfathered in" to allow it to have a limited number of wild boar on the property.
