A voluntary control program for Johne's disease has been in place in the US since 2002. Although participation in the program by producers has been lower than expected, veterinarians and producers have gained access to information and new testing methods to address the disease. Previous National Animal Health Monitoring System dairy studies were compared to the most recent study conducted in 2007, and results indicate that since 1996, producers are much more familiar with Johne's disease and have implemented control measures to reduce the prevalence of disease. However, the herd-level prevalence on dairy operations in the US is much higher than previously reported.
