Scrapie Information for Sheep & Goats - In 2001 the USDA initiated a program to eradicate scrapie from the nation's sheep flocks and goat herds. The NE State Fair requires that all sheep and goats be identified with a scrapie tag and these are the guidelines that Knox County follows. If you need tags - call toll free 1-866-873-2824, select option 7 to request official ear tags at no cost and/or a flock ID number.
