How long does a restriction last?

Information on how long a restriction will last because of a Tuberculosis (TB) reactor animal being found in a herd.

Generally herds are restricted until 2 consecutive clear test results have been obtained. The first test of a restricted herd is carried out not less than 60 days after the removal of reactors from the herd. The next test of a restricted herd is done not less than 60 days after the first test. If both these tests are clear and cleansing and disinfection have been carried out to the satisfaction of Department of Agriculture and Rural Development (DARD) inspectors, the herd will be derestricted.

If TB has not been confirmed in the herd, it may be possible to derestrict the herd after a single clear herd test is carried out not less than 60 days after the removal of reactors.
