Denmark – Operation Paratuberculosis

The Danish program on bovine paratuberculosis, launched in 2006, is a voluntary control program. The program aims to provide Danish dairy farmers with options to, in the most economic and welfare advantageous manner, enable them to reduce the prevalence and impact of paratuberculosis. The website has two excellent videos describing the program.

U.S.A.H.A. Johne's Disease Committee
U.S. Animal Health Association

The USAHA is a non-governmental organization with members representing animal producers, governmental regulatory agencies concerned with animal health, and researchers interested in animal diseases. At the annual meeting the Johne's Disease Committee learns of new information about the disease and formulates resolutions that give direction to the USDA on actions the Committee thinks are necessary to help control this disease. The site contains annual committee reports back to 1997 and history of past resolutions and actions taken by USDA in response to these resolutions.

U.S. NVSL - approved Johne's disease testing laboratories
USDA-APHIS National Veterinary Services Laboratory

A product of the NJWG was creation of a system for approving laboratories as being proficient to perform diagnostic tests for Johne's disease. At present approval for two types of test are available; M. paratuberculosis detection (culture, PCR or any other method) and ELISA (a blood test). Laboratories must successfully pass this test annually to be on the approved list. The list becomes available by November 1 each year but it frequently takes several months for this website to be updated.

Survey for Johne's disease in U.S. dairy cattle herds
USDA-APHIS-VS Centers for Epidemiology and Animal Health (CEAH)

In 1996 a U.S. Dept. of Agriculture agency, CEAH, surveyed dairy cattle herds in the U.S. for Johne's disease. They also gauged producer awareness and estimated the economic of Johne's disease. The full report of their findings is available at the CEAH website.

In 1997 a U.S. Dept. of Agriculture agency, CEAH, surveyed beef cattle herds (those that produce calves, referred to as cow-calf herds in the U.S. and beef suckler herds in many other countries) in the U.S. for Johne's disease. They also gauged producer awareness and estimated the economic impact of Johne's disease. The full report of their findings is available at the CEAH website.
