JOHNE'S DISEASE CONTROL IN■CANADA 2014-2016:PREVALENCE, STATUS PROGRAMAND COMMUNICATION

摘要

Johne's disease (JD) continues to be an important production-limiting disease of dairy cattle. Additionally, concern over potential public reaction to Mycobacterium avium subspecies paratuberculosis (MAP) as a potential zoonotic agent has stimulated the development of provincial or regional JD control programs across the country over the last 10 years. These programs were implemented provincially with coordination at the national level to ensure some degree of uniformity of practice because cattle frequently move between provinces. The Canadian Johne's Disease Initiative (CJDI) coordinated provincial JD control activities across Canada from 2009 to 2013. The CJDI, funded by Dairy Farmers of Canada and the Canadian Cattlemen's Association, was guidedby its Advisory and Technical Committees (each with representation from industry, veterinary schools and provincial programs). The CJDI priorities were: (1) to increase education about and awareness of JD across Canada among dairy producers, veterinarians and allied industries; (2) to encourage the development and implementation of control programs in all ten Canadian provinces and where possible to support coordination between these programs; and (3) to facilitate the development and funding of research programs in areas that support the coordinated mission of JD control. The CJDI reached the end of its funded mandate in 2013 and there has not been any formal coordinated national JD activity since. We continue to maintain an informal national working group, which meets annually to discuss regional activities and issues, including how to keep JD awareness in the minds of dairy producers and promotion of the implementation of a national JD status program.
