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

Abstract

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.
