Billing said the Australian agriculture sector had increased biosecurity measures in response to the foot and mouthoutbreak in the UK in 2001,which resulted in the destruction of 6 million pigs,sheep and cows. “The outbreak in the UK put a jolt through the industry.”
But dairy farms face particular challenges in mitigating disease outbreaks. On Billing’s farm,the virus could quickly spread among the herd,which moves together as the cows go into the dairy for milking twice daily.
Milk cannot be stored for long periods on farms,so tankers arrive every day to empty the huge vats and take milk away for processing. Mud and dirt stuck to vehicles can spread viruses between farms.
Billing has some frozen embryos from his best cows,so he can produce offspring using surrogate cows.
He said farmers who sold stud bulls were increasingly talking about freezing embryos in case they have to slaughter their animals to contain a disease outbreak.
As part of increased biosecurity measures,Billing is taking more detailed records of who visits his farm and will soon install shoe-cleaning equipment. There is restricted access to the calf sheds and the dairy is cleaned and sanitised twice a day.
If there is a local foot and mouth outbreak,any vehicle that visits a farm will have to be washed before it can leave and farmers will have to stay put on their properties in affected areas.
Last week,the federal government promised to introduce thetoughest biosecurity measures at airports to guard against an outbreak of foot and mouth disease. All mail arriving from Indonesia and Chinais now being screened for the virus.
Australian Airports Association chief executive James Goodwin saidsanitation foot mats had been installed at airports in Melbourne,Sydney and Adelaide.
He said there had been some delays disembarking because some travellers had stopped to ask questions of officials about declaration of goods from overseas.
“The early indications are Australian travellers are taking this very seriously,” he said.
This week,Victorian zoos also restricted visitor access to certain animal enclosures in a bid to prevent the spread of the disease.
Zoos Victoria chief executive Jenny Gray said paid encounters with giraffes,kangaroos and elephants,where visitors are guided through the exhibit by a zookeeper,had been cancelled and existing bookings refunded.

People living with livestock have been asked to avoid going to the zoo and those arriving in Australia from Indonesia have been told to wait 48 hours before visiting.
Billing is worried about the welfare of people and animals if Australia’s biosecurity measures fail to keep foot and mouth disease at bay. He said the economies of many towns across Victoria,such as Colac,relied on agriculture for their survival.
“The impact on rural communities will be massive if the disease gets in,” he said.
