That must be such a relief. Very happy for you. And better safe than sorry with your hazmat stuff.
Why would you need to rebuild? Is there no way of disinfecting the ground, barns etc? Bleach solution everywhere? Starting over makes no sense to that extent?CL is one disease I would be pretty strict about. CAE is just much easier to prevent and get rid of...but CL is hard to kill in an environment. I would be thinking hard about how important your current goats are to you and how hard you are willing to work to get rid of this. Can you feasibly set up a whole new area, shelter, feeders, etc to put clean stock in? You can get kids out of infected stock, pull at birth and raise on pastuerized milk, keep in your "clean" area being super careful not to cross-contaminate with your clothes, boots, feed buckets, etc. Test and test and eventually weed out every positive goat and let your old facilities rest for a few years. If you have accurate test results and your goats are indeed positive, you will be fighting this for a few years unless you decide to ignore it. Also...you will have a hard time honestly selling breeding stock. I would buy from someone with CAE as long as they test and pull kids, etc but I wouldn't take the chance with CL. The other option is to start over....which may be the quickest but not always possible either. You still would need new barns/ground and you still will be on pins and needles wondering if it will show up again.
Note that the previous post was from 2009. New data may be different. CL vaccines were available in 2009 and the big issue with it was that the vaccinated animals would test positive for CL whether they had CL or not.Why would you need to rebuild?
