Australian Johne's disease rules change on June 30, 2017, when most states deregulate on-farm management. Producers selling cattle across borders into the Northern Territory or Western Australia could lose market access if they do not adopt required biosecurity plans.
Producers in Queensland and South Australia who ship live cattle out of Darwin are most at risk.
Lost access to Northern Territory and Western Australian markets could tighten some Australian cattle movements. The effect on global feed or grain prices is negligible.
After 356 past disease events, Live Cattle moved a median +0.2% over 5 sessions (54% higher; middle half -0.8% to +1.1%), and +1.1% over 20.
After 266 past disease events, Feeder Cattle moved a median +0.5% over 5 sessions (59% higher; middle half -1.1% to +1.7%), and +1.7% over 20.
