Three more captive deer in Central New York have tested positive for chronic wasting disease, raising the total to five statewide.
State agriculture officials say the three deer belonged to the same Oneida County herd that last week yielded the first confirmed case of the fatal neurological illness. The second case came from another captive herd in Oneida County.
A Cornell University lab tested 20 deer from both herds, with the three testing positive, according to the state Department of Agriculture & Markets.
Chronic wasting disease -- called CWD -- has been detected in wild and captive deer and elk populations in 12 states in the West and Midwest. Though it is deadly to some deer and elk species, there is no evidence that CWD is harmful to humans or other domestic livestock.
State environmental officials have announced plans to kill 420 wild deer in Oneida County starting next week to see if the disease has spread. Brain tissue will be collected and tested to see if the disease has been contracted by any deer in the wild.
