The objective of this study is to present the results of a research carried out on a group of farms involved in pig fattening (48 farms) to evaluate the economic impact of implementing human and animal health regulation. The five types considered in any case represent 90-95% of the total health costs, there are therefore economies of scale and considering the types of expenditure, veterinary medicines have a strong incidence on fattening farms, together with medicated feed for consumption on the farm and the control of Aujeszky's disease. The overall health costs have on average reached the 2% of total costs and the same value of the net income.
