I can't remember where, but I think it was mentioned on GW that to be TB/Brucellosis free, you had to sign up for some government thing and test twice a year. From what I read, it wasn't a good idea since it would be easier for somebody to accidently get mixed up in NAIS against their will.
I believe you have to go through the USDA or something like that. yes the entire herd has to be tested to become certified. I believe you have to establish yourself as a closed herd too. but im not sure on that. I will call vicky later and see. Though she is being certified to be a dairy. I would call the show secretary and see what they require. Because if your going to show obviously you can't classify yourself as a closed herd. I know legally they have to have a TB test to cross state lines. Could this be what they are trying to enforce?
