: A large-scale foot and mouth disease (FMD) epidemic in Japan in 2010 caused severe economic losses for livestock and related industries. In this paper, the authors develop a clear and usable framework to estimate the economic impact of this FMD outbreak. An economic analysis is then conducted by combining this framework with an epidemiological model. The framework estimates the direct and indirect costs to livestock and related industries by applying an input-output model, as well as by addressing expenditure on disease control. The direct cost to the livestock industry was estimated at 51.2 billion Japanese yen (JPY), engendering an indirect cost to related industries of JPY 25.5 billion. The expenditure for disease control activities was estimated at JPY 8.2 billion. The total impact of the 2010 FMD epidemic was estimated at almost JPY 85 billion. Within the economic analysis, the authors evaluate several control measure scenarios: a baseline scenario, which assumes that the rapid disease spread observed in the early phase of the 2010 FMD epidemic would continue; prompt culling within 24 hours; early detection of the first case; and emergency vaccination within a radius of 10 km around the affected farms in either seven or 28 days. Prompt culling and early detection were superior from an economic point of view, reducing the total economic impact to 30% and 2% of that in the baseline scenario, respectively. Compared with these scenarios, vaccination was less cost effective. However, vaccination suppressed the speed of disease spread and shortened the duration of the epidemic, suggesting its potential effectiveness in curbing rapid disease spread in a densely populated area.
