Economic losses resulting from bovine cysticercosis with special reference to Botswana and Kenya.

Economic losses from cysticercosis are determined by disease prevalence, grade of animals infested, potential markets, prices of cattle and treatment costs for detained carcasses. The main features of the livestock economics of Botswana and Kenya are discussed. Botswana is more dependent on meat exports than Kenya and its cattle prices are much higher. The incidence of cysticercosis at export abattoirs in Botswana and Kenya is about 8 and 20% respectively. Annual losses in Botswana now approach 0-5 million pounds, while in Kenya they are about 1 million pounds. The loss per animal slaughtered is 2-25 pounds in Botswana and 1-50 pounds in Kenya. Some implications for veterinary research in this area are examined. Blanket treatment with a drug or vaccine would only be economical where prevalence was very high. An in vivo diagnostic test would be of use mainly with high value cattle.
