CWD testing is not only slow; it’s also literally all over the map. Some states prioritize CWD testing more than others. In 2017, there were 100,000 deer tested nationwide, but nearly 25,000 of those were tested in Missouri alone. Prior to 2015, Tennessee was testing only a few hundred samples per year, according to James Kelley, deer management program leader for the Tennessee Wildlife Resources Agency. “[Then] it was detected in Arkansas [in 2015], and that made us nervous,” Kelley says. “We made a concerted effort to up our sampling and set a goal of collecting 1,500 samples statewide.” However, that was concentrated in the two regions with the highest annual harvest, while other regions saw far less testing. On one hand, it makes no sense to test thousands of deer on one side of a state line and dozens or none 5 miles away. On the other, few state agencies can afford to conduct large-scale testing uniformly across the state.
