Eradication of Aujeszky's disease from New Zealand pig herds 1976-1997.

Aujeszky's disease was first diagnosed in the North Island of New Zealand in 1976. It has never been reported in the South Island. An industry-funded eradication programme was initiated in 1989 to eradicate the disease from the national pig herd. By using a combination of serological surveys, abattoir surveillance, test and slaughter, depopulation, vaccination and movement restrictions, Aujeszky's disease was eradicated by 1997.
