Following withdrawal of restrictions a six month check test (6M test) is carried out six months from the date of the last short interval test. If the 6M test is clear, the herd returns to routine six-monthly surveillance testing.
A herd check test six months from the date of the last short interval test is carried out. If the six month check test (6M test) is clear, a further herd check test is carried out 12 months later (i.e. 18 months after the last short interval test). If the 12 month check test (12M test) is clear, the herd returns to routine annual surveillance testing.
A herd check test (12M test) is carried out 8-12 months from the date of the last short interval test for herds on four-yearly surveillance testing. If the 12 month check test (12M test) is clear, the herd returns to routine four-yearly surveillance testing. Post-breakdown herds are subject to pre-movement testing requirements until they return to their four-yearly testing interval.
