I have hunted very near that ranch for several years and even hunted it a few times before the owners fenced it off for raising elk. The problem is that the cow elk that had TB had been tested 14 times BEFORE she came up with TB. The elk were bought through a federal program that tested and guaranteed the "quality" of these elk. My girfriend just filled her cow tag about 5 miles from this ranch a couple of weeks ago and we gave the head and neck to ODFW to test for TB. Have not heard anything but cooking your meat to 150 will kill the culprit anyway.
The worse case of TB ever reported came from Michigan with a believe 8 or 9 animals were involved. ODFW wanted to kill something 500 deer and 200 elk within a 5 mile area of the Rudio Ranch (this is were the elk are) and my buddy runs 125,000 acres surrounding the ranch. He told them to pound sand, but he would cooperate with providing test samples from the animals his hunters take off the property. The problem with TB is there is no cure for it and eradication is the only solution--some of you old timers will remember the TB outbreaks of the 60's I am sure. Seems we still have animals out there..............hmmmm. Nature seems to have a way of taking care of her own.
For the record--canned hunts should not ever be allowed here in the state on native game animals at least! I think they outlawed them too though, there used to be a ranch out of Madras that had some exotics and I think they shut them down a couple of years ago.
