Estimating the production losses due to cystic echinococcosis in ruminants in Turkey.

The aim of this study was to estimate the production losses due to cystic echinococcosis (CE) in cattle, sheep and goats in Turkey. For this purpose, official records and previously published data in the literature were used. The weighted mean prevalence rates of the disease were calculated to be 7.4% in cattle, 46.3% in sheep and 10.9% in goats. The financial losses were estimated in US$ at 2008 current prices under expected (mean value), optimistic (mean value lowered by 10%), and pessimistic (mean value increased by 10%) scenarios. The production losses in an infected ruminant were estimated as US$ 139.2 (125.3-153.2, under optimistic-pessimistic scenarios) for cattle, US$ 13.7 (12.3-15.1) for sheep, and US$ 13.9 (12.5-15.3) for goats. The nation-wide annual losses due to CE were estimated as US$ 32.4 million (26.2-39.1) for cattle, US$ 54.1 million (43.8-65.5) for sheep and US$ 2.7 million (2.2-3.3) for goats. The nation-wide production losses due to CE in Turkey in 2008 were calculated as US$ 89.2 million (72.2-107.9). The results of this study may provide information to assist decisions of the policy makers in prioritising the allocation of scarce resources in controlling animal diseases in Turkey. However, alternative disease control-eradication programmes and cost-benefit analyses of them are needed for the future studies of this kind to provide better decision support in this area.
