The National Ovine Johne's Disease Control and Evaluation Program (NOJDP) is a AUD40.1 million, six- year program aimed at delivering necessary information on the national distribution of the disease and the technological tools and information needed for an informed decision on the future management of OJD. At the same time, the Program set out to control the disease during this evaluation phase. The Program is jointly funded by Commonwealth and State governments and national and state industry bodies through levies on producers. The NOJDP is now in its fourth year and has made significant progress, including extensive surveillance that has enabled better definition of disease distribution, the implementation of 21 research projects (worth AUD5.6 million with a further AUD2.4 million planned) and the implementation of a communications program. A Mid-Term Review was undertaken to assess whether the Program was meeting its objectives and whether those funding the Program were still supportive of its aims and its operation. A revised three-year Plan has been adopted for the second half of the Program. In addition to the ongoing commitment to research and surveillance, the revised Plan incorporates a specific Control subprogram and a new national Financial Assistance subprogram to support the NOJDP. Despite its success, the Program continues to face a number of challenges. The identification of infected flocks through increased surveillance, together with trading restrictions placed on infected and suspect flocks and flocks in high risk areas has brought opposition from those affected. This is mainly from some sectors of the pedigree breeding industry and in States where, to date, there has been little or no financial assistance. The issue of financial assistance is currently being addressed through both national industry and State initiatives. Delivery of an effective assistance package is essential to ensure the successful completion of the Program.
