NORWAY An example of a daring yet successful campaign in the face of an act not especially well designed or heeded by owners at first, and started with incomplete knowledge of disease prevalence, plus difficult rules about common pasteurizing. Essentially: blood samples from infected herds taken twice annually and reactors sold for slaughter; Stables disinfected.
