The costs of controlling and eradicating the epidemic of Newcastle disease
in Northern Ireland in 1973 are presented. The parameters of the 1973 epide
mic have been adjusted to simulate the effect of the same epidemic in 1997,
taking into account the relative changes of input and output prices, and t
he changes in the structure of the poultry industry. The costs and their di
stribution between producers, government and the industry, in 1973 and 1997
are compared, and the costs of an alternative vaccination strategy are com
pared with the eradication policy in both years.
