In the worst-case scenario, billions would have to be spent on a national response and scores of painfully diseased cattle, sheep, pigs and goats could be culled, the Australian Broadcasting Corporation reports.
"Overnight, Australia's international livestock markets would close. An outbreak could wipe more than $80 billion from the national economy. Livelihoods up and down the country would be at risk.
"If it seems like a problem purely to be managed by Australian farmers — it is not. There is every likelihood FMD could be unsuspectingly brought in and spread throughout Australia by members of the public," the ABC reported.
Over the past two years of the pandemic, many in the Pacific have prided themselves on the actions they have taken to 'stop the spread' of Covid-19.
Now, restriction-weary members of the public once again have a role to play in avoiding being part of the spread of a highly infectious disease.

"Foot-and-mouth disease is not in Australia. That is the tentative good news. It has been 150 years since it was last present here, but it has never been closer," the ABC reported.

FMD spreads between animals via their breath, through contact with the blisters, and through infected milk, semen, faeces and urine.
