Council Directive 92/102/EEC of 27 November 1992 sets down minimum animal identification and registration requirements. In brief, these include that: all member states must maintain a register of all holdings containing cattle, sheep, goats and pigs; farmers must maintain records of animals on their holdings and movements on and off their farms; animals must be identified in such a manner that it is possible to trace back to their farm of origin.
The implementation dates for the Directive are 1 October 1993 (bovines), 1 January 1994 (pigs) and 1 January 1995 (sheep and goats).
My Department is in the process of making the necessary arrangements to implement the Directive.
