A cattle herd suspected in a potential bovine tuberculosis (TB) outbreak has been found free of the disease and released from quarantine, says the North Dakota Department of Agriculture.
Last October, State Veterinarian Susan Keller was notified that a cow originating from southwest North Dakota was identified at a Minnesota slaughter plant as a suspect for TB. The diagnosis was later confirmed and a herd investigation was initiated.
Two whole-herd tests have been completed on the suspect herd. All tests were negative and the quarantine was lifted last Friday. Testing on two of four neighboring herds is complete with results on a third neighboring herd expected shortly. Testing of the fourth herd will begin this month.
