“Tuberculosis in humans and animals: are we a threat to each other?”
In the past 20 years the number of infected herds has increased from 88 to 5,539 per year. The main reason is probably increased rates of cattle to cattle transmission as animals are increasingly moved from farm to farm. There is a highly effective test of disease status; it should be possible to isolate infected cattle.
Cause of loss could be traced to a duty-holder.
