A cross-sectional study on bovine cysticercosis was conducted at Zeway municipal abattoir from November 2010 to March 2011 with the main objectives of determining the prevalence of cysticercosis in animals, taeniasis in human and estimates the worth of taeniasis treatment in Zeway/Batu town. Active abattoir and questionnaire survey and inventory of pharmaceutical shops were performed to accomplish the study. Out of the total 400 inspected animals, 12 animals had variable number of Cysticercus bovis giving an overall prevalence of 12 (3%). Anatomical distribution of the cyst showed that the highest proportions of C.bovis cyst were observed in tongue 33 (34.4%) followed by heart 27 (28.1%), triceps 21 (21.9%) and masseter muscle 15(15.6%). A total of 96 C. bovis were collected during the inspection; out of these, 32 (33.3%) were found to be live cysts while 64 (66.7%) were degenerative cysts. Of the total 120 interviewed respondents, 68 (56.7%) had contracted T. saginata infection at least once in their life time. Human taeniasis prevalence showed significant difference (p<0.05) with habit of raw meat consumption, sex and use of latrine. Accordingly frequent raw meat consumers (OR=10.71, 95%CI [1.54-74.42], male individuals (OR=2.15, 95% CI [0.95-4.88] and non latrine users (OR=4.40, 95% CI [1.58-12.45] had higher odds for acquiring taeniasis than occasional meat consumer, female and latrine users, respectively. An inventory of taeniacidal drugs from private pharmacies, rural drug venders, clinics and public health centers indicate that drugs worth of 110,560 Ethiopian birr was sold in the past one year (2009/10). Therefore, attention should be given for awareness creation for people not to consume raw meat and to use latrine to decrease the contamination of grazing areas.
