If he knows so much about the problem he should be turning the people into the authorities. The guys that do movement of animals without paper work and testing get caught sooner or later.

Mama always says: You play with trash - you get some on you. Tell me - have you had any experience with microchips? How can you make them read differently?

It's intresting research for sure. Seems more or less like a good way to trace the spread of a disease effectively backward. But, I think it would have sever limitations.
For instance, I live in Central MN and have deer pens on drained peat bog, crushed sandstone/clay, glacial till (sand and gravel), along with ancient lakeshore sand and brown clay. With this many different soil types on a single farm, you would almost need samples from every pen wouldn't you? On wild deer, yes all the soil types should more or less equal out, but pen raised deer are more limited in their travels and thus they might be way off baseline.
Another potential problem would be soil transfer. Example; in attempt to neutralize some acid soil we had a load of crushed limestone brought in from southern Nebraska. Perhaps deer from that pen catches some dreaded disease and dies. The isotope test comes back saying the deer is from a southern region of NE. Since no deer farms are in that area, obviously that deer orginated from the wild and obviously we are guilty of a multitude of crimes even though that deer was born in the pen he died in.
I think it's good research, but the application might be problematic as a test.
Scott Heinrich said:Truby do I undrstand correctly that that this method works only on samples that come from deer whose whereabouts for the last 3 months to a year are known? How would this type of variable location data be useful? If you were to locate a diseased animal, how would you know its "origin" if the tracers are only good back to 12 months or so and the gestation period on the disease is 12-16 months? By the time deer with CWD become symptomatic, they may have exceeded the window for your test to be accurate. I guess I need to do some more research into this to fully understand the validity of the test. I want to be certain the USDA isn't going to develop this into an accepted standard like their TB screening test and have something that gives as many false positives as that.
