Oregon’s county fair season is about to shift into high gear in the weeks to come.   That means it’s time to emphasize good biosecurity to protect animals and people from disease.  Oregon Department of Agriculture field veterinarian Ryan Scholz says biosecurity is the best way to keep animals healthy before, during, and after events.  Scholz says exhibitioners need to monitor their animals closely before bringing them to a fair, show, or competition.  Afterwards, livestock owners need to isolate their animals from other animals back home for up to four weeks in case they harbor a virus.  Outbreaks this year of high path avian influenza in backyard birds and equine herpes virus in horses underscore the importance of biosecurity.
