In the US, scrapie has caused certain bloodlines to be disfavored and discontinued due to the genetic susceptibility to scrapie. In addition, flocks are monitored for the presence of scrapie and if a scrapie problem is detected the flock may be depopulated (destroyed) or the lambs have to be carefully raised by hand to get the infectious protein out of the flock.
