Although 171 of the pigs had died and 270 were found sick, ministry regulations require all pigs on an affected farm be culled and disposed of and the area quarantined and decontaminated.

The laboratory’s director is Dr Trevor Drew.“I do not think I really expected African swine fever to spread with such ferocity,” said Drew. “I think we will not be able to control African swine fever until there is a vaccine available.”Without a vaccine, Australia will rely on traditional methods of disease control should ASF reach its shores. Infected pigs would be culled, their carcasses buried and farms disinfected.Australia’s multi-million dollar pork industry includes about 2,700 producers, which employ 34,000 people.US Halts Polish Pork Imports Over African Swine Fever
