I have confidence that what Jeremy says is true. I also personally do not believe that Jeremy, Rob, et al would toss a visibly sick snake in a box and go on their way.
You have to consider that a non-zero positive rate (based on the capabilities of the test) still has to beat an "out of sight out of mind" policy, right? I tested for and detected it but they can't with the exact same technology?
Walking Tinley NARBC with known-unknown animals from a building full of known-unknowns is a bit opposite to Jeremy's words. Pushing snakes out the door without even a basic test is, too.
Even scarier, according to all the DNS banter from randoms in the thread, it's apparently a community wide belief that it's better to dump unhealthy snakes on customers than spend any money on testing.
If we can get people testing the two-way shipping would definitely be a punch to the wallet cost over preemptive testing for known knowns. Upcharge me for the test as an optional service. No problem. Other people can do it.
