Caveat: most information on M. paratuberculosis infection and Johne’s disease has been obtained through studies on domestic species (for example cattle, sheep, goats). While it is believed that this information likely is applicable to bison as well, there may be some facets that differ for which we do not yet have a good understanding. Please bear this in mind as you use this web-site.

Bison transported across state lines are subject to the federal and state regulations. The veterinarian from the shipping state is liable for all statements made on the health certificate concerning the infectious disease status of animals being transferred. New regulations for Johne’s disease control, including transit rules, are being developed both on the state and national level in the United States. These new regulations may affect the feasibility of and transit protocols for both test-positive or test-negative animals.

For rules and regulations governing control programs, liability from sale of infected animals or other issues concerning Johne’s disease contact your state/provincial/national animal health department.

While not directly pertinent to bison in some aspects, see the web pages under Dairy-Laws for a broader description of this topic.
