Cheyenne, Wy – State officials finally got some better news concerning Brucellosis. An infected Cow found in Riverton, has been traced back to the herd in Sublette County where Brucellosis was first detected. It means there is no evidence that the disease is in more then one herd. Preliminary tests showed brucellosis in about 30 of 391 head on the ranch southeast of Pinedale. Final tests are being done at the National Veterinary Services Laboratory in Ames, Iowa. But Governor Dave Freudenthal is not optimistic that federal tests will show anything different. Freudenthal says he will attend a meeting in Pinedale Monday where he says emotions are high. But he says it is hard to evaluate what the actual implications are until all the information is in.
