Biosecurity Practices for Mycobacterium avium subspecies paratuberculosis Infection, Salmonellosis, and Bovine Leukemia Virus on Cattle Operations.

Mycobacterium avium subspecies paratuberculosis infection, salmonellosis, and bovine leukosis virus are important dairy and beef cattle diseases from a health perspective. For herds without infection, keeping the disease out through testing of source herds should be prioritized. For herds with infection, control programs should be instituted and followed to reduce the prevalence and ultimately eliminate the disease.
