Cysticercosis of slaughtered cattle in northwestern Ethiopia.

Abstract

The occurrence of cysticercosis due to Taenia saginata in cattle slaughtered for meat in Amhara National Regional State, northwestern Ethiopia between September 2005 and February 2007 was investigated. Routine meat inspection of various organs of 4456 cattle in eight abattoirs of this region showed that 824 (18.49%) were infected with Cysticercus bovis. The occurrence rate did not vary significantly from abattoir to abattoir (P>0.5). The tongue, masseter muscles, heart muscles, triceps muscles and thigh muscles were the main predilection sites of the cysts. Of 4102 male cattle, examined, 768 (18.72%) had cysts of C. bovis while 56 (15.82%) of the 354 female animals investigated were infected. The animals slaughtered were all adults. No significant difference in occurrence was recorded between the sexes. Monthly occurrence of the cysts in the animals revealed a rise of infected animals during the dry season.
