What are your options for cleaning up blue ear disease?

Blue ear virus is prone to mutation. Regardless of whether the whole herd of sows on the farm has become immune to the latest outbreak of blue ear disease, or the whole herd has been replaced and all pigs are negative for blue ear disease, these farms are still vulnerable to blue ear disease outbreaks from different virus strains. This means: we must ensure that biosecurity procedures are implemented at all times to protect our farms.
