From a blog that I check once in a while:
"The USDA in conjunction with the University of Colorado have been doing research on reliable live testing for CWD for some time now. Earlier this past spring more live test were being done and through Tonsilar swabs and Nasal swabs have produced very accurate and reliable live test data. Test were done on free range deer in Colorado, Wyoming and several large captive deer herds were tested ,test results of the first three captive herds showed no trace of prions in test animals. Free range animals that were tested showed both positive and non positive results in real time. More live test were just done in NY via tonsil swabs and nasal swabs with great results. Herd that was tested in NY came back negative. This along with tonsilar biopsy and or rectal biopsy show great leaps in research in just the past 5 years."
