How widespread is MCF in the commercial bison industry ?
We are aware of cases in 11 states (Utah, Wyoming, Colorado, Montana, California, Oregon, Ohio, Kansas, Nebraska, North and South Dakota) and three Canadian provinces (Saskatchewan, Ontario and Alberta). The disease is widespread in the bison industry and is commonly misdiagnosed due to lack of specific clinical signs. Many veterinarians are not aware that the post-mortem changes of MCF are somewhat different from those in cattle, and that additional tests are required to make a firm diagnosis of MCF.
