Bovine cysticercosis: prevalence, cyst viability and distribution in cattle slaughtered at Kombolcha Elfora meat factory, Ethiopia.

摘要

A cross-sectional study on bovine cysticercosis was conducted at Kombolcha Elfora meat factory from October 2009 to March 2010 with the objectives of determining the prevalence of Taenia saginata cysticercosis, cyst viability, distribution and its public health implication. A total of 420 carcasses were examined during the study period, of which 28(6.7%) were infected with T. saginata metacestodes. A total of 160 cysticerci were detected, of which 110 (68.7%) were live. The prevalence of infection varied significantly between age (p<0.05), but no statistical significance difference between sex and origin of animals. On the other hand, the questionnaire survey indicated that Taenia saginata taeniasis was a public health problem in the town and its surrounding areas in which, 62 (31%) had contracted T. saginata infection at least once in their life time from the total of 200 interviewed individuals. From this, 62.8% (44 of 70) had habits of raw meat consumption. There was statistically significant (p<0.05) difference between the prevalence of taeniasis between individuals which had habit of raw meat consumption and individuals consuming cooked meat. Therefore attention should be given for awareness creation for the people not to consume raw meat and to use toilets to decrease the contamination of grazing areas.
