Source: Michigan Department of Natural ResourcesLANSING - The Michigan departments of Agriculture (MDA) and Natural Resources (DNR) today confirmed the state's first case of Chronic Wasting Disease (CWD) in a three-year old white-tailed deer from a privately owned cervid (POC) facility in Kent County. The state has quarantined all POC facilities, prohibiting the movement of all - dead or alive - privately-owned deer, elk or moose. Officials do not yet know how the deer may have contracted the disease. To date, there is no evidence that CWD presents a risk to humans.
Source: The Grand Rapids PressStatewide, 1,095 deer have been tested, with 964 testing clean and 131 awaiting results. More than 300 wild Kent County deer have been tested and found to be clear of chronic wasting disease after the highly contagious disorder was found in one northern Kent County farm-raised deer in August.
Approximately $1 million spent on testing
