Abstract
The stud y was made from October 2005 to April 2006 at the Southern Nat ion, ationalities
and Peoples Regi on. Awassa town and its su rroundings. It was carried out with the overall
objecti ve of providing base line data on the prevalence of C bovis'T saginata. A total of 400
carcasses of randomly selected bovine animals we re used fOT the active abattoir survey. The
study comprised of an active abattoir survey data collection at Awassa municipal abattoir.
questionnaire sur. cy on \ 'oluntecr respondents and an inventory of phannaceutical drug stores
and shops in Awassa town. Of the 400 carcasses examined during the study period. 105
(26.25%) were infected with C. bonos. The distribution of organs tissues infected with C. bO \'is

shoulder (9°'0) . tongue (3.25° '0). and liver (0.75°0). Analysis of active abattoir survey revealed
that there was a significant difference ( P < 0.05. OR = 3.34) between breeds. but there were no
significant differences observed in the infection rates between sex (P > 0.05. ;( = 0.02) and
origin (P > 0.05. OR = 0.87) of the animals. The viability test on all isolated bladder WOnTIS
showed that -l4.2% were viable. The tonf,1Uc. heart. shoulder and masseter muscles had the
highest number of viable (11.25°0), (9°0), (8.5°0) cysts respectively. Based on the
questionnaire SUI\'cy. T. saginaw taeniasis is a v .. ide spread problem In Awassa town and it s
surroundings. 64.1 00 of the respondents had contracted taeniasis due to T. saginala. The
potential risk factors of taeniasis namely. age. sex. religion. occupation, educational le\ cis,
raw meet consumption. use of spices during meat consumptio n and marital status were
considered . The pre\alence of taeniosis was slightly significant by the age of the respondents
(P<O.05 and /=6.23). There was no associalion between the pre\-aience of taeniasis and sex
(P> 0.05 and ;! = 0.44). Among ~ luslim and Christian communities. it was found that there
was a statistical significant difference in the pre\·alence oftaemosis (P<O.05 and OR = 5.34).
higher in the Christian communities. Statistical analysis indicated that there was a significant
difference between occupation between low and high·risk groups (P<O.OO I and z' = 15. 7 9) .
Educational backgrounds had no signi ficant association with the prevalence of taeniosis
(P>0.05 and OR = 0.7 1). The prevalence of tacniosis was highly signilicant (P<O.OOI and OR
= .47) in the ra\\ meat eaters as compared to those consuming cooked meat. The use of spices

during meat consumption was analyzed and found to be significant in th ose who had the habit
of using spices with meat (P<O.OO I and OR ~ 12.03) . Marital status had also significant effect
on the prevalence of taeniosis among the respondent s (P <0.05 and r= 7.00), higher in married
ones. In addition ; multivariate ana lysis (logistic regression) showed that raw meat
consumption, occupation and use of spices with meat were important risk factors for taeniosis.
Statistical ana lysis showed that preferences of the available taenicidal drugs among the
respondents wcre Nielosamide (62.5%), Mebendazolc (56.67%), Albendazole (53.3 3%) and
Praziquantel (48.33 %). The annual taenicidal drug treatment cost in the stud y area from 2002-
2005 by prescription and complaint s of patients was estimated to be 7. 2 I 9,01 9.95 Eth. Birr.
The drug inventory clearly demonstrated the economic sign ifi cance of T. saginata taeniosis in
the stud y area. According to the respondents. the use of traditional herb al tacnicidal drugs wa s
not commonly practiced. But it is well understood that a co nsiderable proportion of residents
mainly use herbal drugs due to its highly purgative effect and cheaper price. Hence. this
disease deserves serious attention by the various stakeholders in order to safeguard the health
of the residents of Awassa town. consumer and further promote beef industry in the study area
in particular and the country in general. The distribution of T. saginata cysts in carcasses. the
potential ri sk fact ors for taeniosis and the economic impact of this parasite are also discussed
