Under council directive 64/432/EEC, as amended by directive 98/46/EC, the officially tuberculosis free status of a herd is suspended when an inconclusive test result is disclosed in an animal(s) in the herd.
The directive provides a derogation which allows internal trade from such herds provided they had not experienced a TB restriction in the previous three years and provided that no animals from the holding are allowed to enter into intra-community trade until the status of any inconclusive reactors has been resolved.
The status of the inconclusive reactor(s) can be resolved by a further test after 42 days. If this test is clear the officially tuberculosis free status can be restored and animals from the herd would again be eligible for intra-Community trade provided the other conditions for export are fulfilled.
All member states are obliged to comply with the provisions of EU legislation.
