Household Economic Losses and Community Knowledge Determine Control Strategies: A Case of Cerebral Coenurosis in Small Ruminants in Northern Tanzania

Abstract

Cerebral coenurosis affects sheep and goats worldwide and has zoonotic implications. Information on the financial burden and understanding of the disease and control practices may inform control strategies. A cross-sectional study was conducted in Babati and Ngorongoro Districts, Tanzania, to determine economic losses, farmers’ knowledge, and attitudes and practices on the control of coenurosis in small ruminants. A structured questionnaire was administered to 558 households for data collection. The total annual loss was TZS 122.8 M (USD 52.9 K) for Babati and TZS 656.5 M (USD 282.9 K) for Ngorongoro District. The average annual household financial loss was TZS 356.8 K (USD 153.83) for Babati and TZS 3.1 M (USD 1.3 K) for Ngorongoro District. Almost 90% of respondents were aware of coenurosis while less than 1% of the respondents had no knowledge of it at all. The average knowledge score was 5.85 out of 16 (36.6%), which implies a low level of knowledge on coenurosis. About 94% of respondents showed a willingness to participate and pay the control costs. Given the economic loss and favorable attitudes toward control participation, delivery of an educational package on epidemiology and control of coenurosis to livestock keepers may trigger collaborative and sustainable intervention.
