Our industry has no interest in having outbreaks. Let's say authorized personnel who enter and create some disease outbreaks are people doing their best to make sure these animals are healthy. Regulations on something that everybody wishes for would not help the situation. If you give a fine to somebody who is doing their best to keep everybody safe, it wouldn't help the situation.
There are tools that could be useful. For example, better understanding of where these diseases come from through research and also the promotion of best management practices would be useful.
Additional regulation would not bring a lot of efficiency in these circumstances.
