A cross sectional and retrospective studies were conducted from January up to May 2013 to determine the prevalence, estimate direct financial loss and public perception of Cysticercosis and Hydatidosis at Adama Municipal Abattoir, Central Oromia regional state of Ethiopia. Out of 422 cattle examined at the abattoir, the overall prevalence of C. bovis and Hydatidosis were (19.7%) and (27.5%) respectively. The prevalence of both diseases vary significantly varies with the breed, origin and body condition of the animals (p<0.05). Anatomical distribution of Metacestode showed the highest proportion of C. bovis cysts were observed on tongue (37.4%), followed by heart (28.7%) whereas, the highest proportion of calcified Hydatid cyst was recorded on lung (59.7%) followed by liver (15.9%). There were also co-infection of hydatidosis with cysticercosis on organs like heart and kidney. Of the 192 cysts of C. bovis selected for viability tests, the higher proportion of viable cyst (49.3%) were observed on heart. Accordingly, of the total 1670 examined Hydatid cysts, 610 cysts were found to be fertile and further laboratory results of viability showed (9.16%) and (27.4%) motile and non-motile cysts respectively. The rest of 1060 cysts were unfertile of which sterile accounts (16.5%) and that of calcified were found to be (47.0%). From the 1198 Hydatid cysts tested for cyst size, 59.8% were small, 36.0% medium and 5.8 % were found to be large in size. Direct annual financial losses due to organ condemnation were estimated to be 34,927,200 ETB. Questionnaire survey also indicated 18% of respondents had contracted Taeniasis and this significantly varies with risk factors like sex, age, resident area and educational status of the people. On top of these, retrospective study for the year 2011 and 2012 revealed similar trend of the diseases in which from the total 27, 180 cattle were slaughtered, the prevalence of C. bovis and Hydatid cyst was (10.9 % and 46.3%) and (63.3 % and 38.1%) for the consecutive years respectively. The study revealed that continuous existence of Metacestode in the study area having huge public health and economic significance. Hence, implicating the need to alarm different stakeholders to look and improve methods to prevent and control the diseases.
A cross-sectional study was conducted from November 2010 to march 2012 to estimate the prevalence and risk factors associated with the hydatidosis and estimate the financial annual loss incurred due to the disease in cattle slaughtered at Nekemte municipal abattoir. Among the total of 539 cattle examined, 98(18.2%) of them had harbored hydatid cyst(s) in one or more of their offals. From the total of 378 hydatid cysts collected and characterized, 202(53.4%), 163(43.1%), 7(1.9%), 4(1.1%), 2(0.5%) of them were obtained from liver, lung, spleen, kidney and heart, respectively. Of the collected cysts, 159(42.1 %) and 87 (23.02 %) were found to be calcified and fertile, respectively. Among the 87 fertile cysts, 44(50.6) were viable. There was statistically significant association between the body condition of the cattle and the occurrence of hydatidosis (X2=16.337; P<0.05). The estimated annual financial loss incurred due to condemnation of organs and indirect carcass weight loss from hydatidosis was found to be 662,084 ETB. In conclusion, the study indicated that hydatidosis is economically important disease with implication for public health calling for urgent intervention. Public awareness about the epidemiology of the disease and application of the conventional preventive and control measures like detail meat inspection, proper disposal of infected organs and control of stray dogs are recommended to control the disease.
Hydatidosis of slaughtered cattle in Wolaita Sodo Abattoir, southern Ethiopia
Tropical Animal Health and Production, 2009
The study was carried out from July 2007 to June 2008 in Wolaita Sodo Abattoir to assess the status of hydatidosis in cattle. Routine meat inspection, hydatid cyst count and characterization were conducted. Out of 400 cattle slaughtered in Wolaita Sodo Abattoir 64 (16%) animals were found harboring hydatid cysts. Thorough meat inspection in the abattoir revealed that 74 visceral organ were found harboring one or more hydatid cysts. The infection of the lung, liver, spleen and kidney were found to be 45.94% 45.94%, 6.75% and 1.35% respectively. From the total of 283 hydatid cysts counted 153(54.06%), 17(6.00%), 5(1.76%), 108(38.16%) were found to be small, medium, large and calcified cysts respectively and 170(60.28%), 5(1.76%) and 108(38.16%) were sterile, fertile and calcified cysts respectively. The rate of cyst calcification was higher in the liver than in the lung while fertility rate was higher among the cysts of the lung. Hydatid cyst viability rate of 40% was observed.

Hydatidosis was one of the most important parasitic disease of cattle which cause serious economic loss through decreased production and rejection of Caracas. A cross sectional study was conducted to determine the occurrence and to characterize the cyst as well as to estimate economic burden caused by hydatid disease with respect to related potential risk factors in Masha municipal abattoir. Out of the total 384 cattle examined, 50(13%) harboring one or more hydatid cyst. No significant difference was seen with regards to altitude and age of the animals (P > 0.05). Of the total 384 cattle examined higher prevalence was observed in cattle with medium body condition followed by in good body condition animals (P <0.05). Lung was the most affected organ followed by liver in the study. The involvement of lung, Liver, kidney, spleen, heart and both liver & lung together was found to be 4.93%, 3.14%, 0.67%, 1.12%, 0.89 and 0.45% respectively. From the total of 50 cysts counted, 14(26...
A cross-sectional study was conducted at Nekemte Municipal Abattoir of western Ethiopia to determine the prevalence, Public Significance and financial loss of Bovine hydatidosis from December 2013 to April 2014. Hydatid cyst count, characterization and financial loss estimation were done on 531 cattle slaughtered in the abattoir. Out of 531 slaughtered cattle, 91 (17.1%) cattle were found to be harbored by the cysts. The prevalence of the disease significantly varies with the breed and origin of the animals (p<0.05). However, the prevalence of the disease was no statistically significant difference among sex, body condition score and age groups (p>0.05). Through detail postmortem meat inspection in the abattoir, 106 visceral organs were found harboring one or more Hydatid cyst. The infestation of the lungs, liver, spleen, heart and kidneys were found to be 47.3%, 30.8%, 2.20%, 1.10 and 3.3% respectively. From the total of 295 Hydatid cysts counted, 174 (59.0%), 113 (38.3%) and 8 (2.71%) were found to be small, medium, large cysts respectively and (53.2%) (21.0%) and (25.8%) were sterile, fertile and calcified respectively. The rate of cyst calcification was higher in the liver than in the lung while fertility rate was higher among the cysts of the lung. The annual direct financial losses from organ and/carcass condemnation due to this disease at the abattoir were estimated to be 3,996,000 Ethiopian Birr (ETB). During study period eight Hydatidosis cases were reported from Nekemte Referral Hospital. Thus; Bovine hydatidosis is considerably a prevalent disease in cattle, with serious public health concern reflections and causes substantial financial losses in cattle in the study area.
Hydatidosis of slaughtered animals in Bahir Dar Abattoir, Northwestern Ethiopia
Tropical Animal Health and Production, 2009
The study was conducted from May 2005 to December 2006 in Bahir Dar Abattoir to assess the current status of hydatidosis in cattle and sheep. Hydatid cyst count and characterization were conducted based on routine meat inspection. Of the total 420 cattle and 340 sheep slaughtered in Bahir Dar Abattoir 143 (34.05%) and 36 (10.6%) animals were found harboring hydatid cysts respectively. Thorough meat inspection in the abattoir revealed that 202 and 54 visceral organs were found harboring one or more hydatid cysts in cattle and sheep respectively. Differences in prevalence rates between the two species of animals were highly significant (P
