Missouri Conservation Officials say two more captive white-tailed deer have tested positive for the fatal illness called Chronic Wasting Disease.
The deer were from the Heartland Wildlife Ranches in Macon County.
The company has been killing off and testing its herd since a deer tested positive in October.
The neurological disease afflicts deer, elk, and moose. Itâ??s contagious among those animals.
But experts say thereâ??s no evidence that it poses a risk to humans, livestock or pets.
