[Jacob-list] certified scrapie free

[Betty Berlenbach]

I guess I'm unsure, then, exactly how scrapie is transmitted. Guess I'll have to do some reading!  Females can't get it from males?  Nor do I understand how having a closed flock means it's scrapie-free, just because it's closed?  Obviously, I'm deficient in the scrapie-understanding-department.  FRED????

        A woman with Shetlands has a scrapie free flock - she says - and it means she has a CLOSED flock of females.  She can sell any sheep and she can bring in rams to breed but cannot add any more females or her date will get reset - she says.

          Laura, Cheryl, et al,

          If the only way you can tell if a sheep has scrapie is through examing its brain when it's dead, how can a flock be certified scrapie free?  I'm just curious as to the process.  I know that the mandatory scrapie program simply has people record who got sold to whom and keep records, in case, when randomly checking for scrapie, they come across a sheep that has it and can then, track it back.  But I'm not entirely sure how the voluntary program works in such a way that it can certify a flock scrapie-free?  All explanations welcome.
