AB  - A cross-sectional abattoir study was conducted
to determine the prevalence of bovine and ovine
fasciolosis and the associated economic loss due to liver
condemnation in three local and two export abattoirs in
Ethiopia. A total of 5427 randomly selected animals
comprising cattle (2257), sheep (1189) and goats (1070)
managed under extensive traditional system and brought
to two export and three municipal abattoirs were exposed
to antmortem and postmortem inspection. Individual
flatworms were identified to species level according to
existing keys and descriptions using their morphologic
characters. Fluke counts and subsequently the lesion score
(severity) were made based on fluke burden and damage
to the liver. All fluke infected livers were considered as
condemned and included in the calculations for the
associated economic losses. A univariable logistic
regression followed by multivariable logistic regression
model was used to investigate the relation and statistical
significance between positivity for liver examination and
the factors considered. A total of 2530 (46.6%±0.059)
livers examined in abattoirs were positive for fasciolosis.
The total number of livers observed in export abattoirs
(Elfora and Helimix) were 2330 (48.4%) while the
remaining 3097 were (51.6%) from municipal abattoirs
(Addis Ababa, DebreBerhan and Bahrdar). The overall
prevalence of fasciolosis observed in ruminants
slaughtered in export abattoirs was 34.6% (877/2530)
whereas it was significantly higher in ruminants
slaughtered at municipal abattoirs 65.2% (1653/2530) as
the whole. The mean annual financial loss recorded
altogether in export and municipal abattoirs was
7,049,638 ETB/335, 697.1 USD. However, the overall
mean financial loss observed in three municipal abattoirs
(5,260,596 ETB/250,504.6 USD) was significantly higher
than the combined loss incurred in two export abattoirs
(1,789,043ETB/85,192.5 USD). The present findings on
ruminants at abattoirs had shown higher prevalence of
fasciolosis (46.6%±0.059) with significant annual
financial loss (1,789,043ETB/85,192.5 USD). This
indicated the economic loss is more significant, since,
animals had shown prevalence above 25%. The high
prevalence of fasciolosis in ruminants coupled with
relatively higher mean annual financial loss observed in
both export and municipal abattoirs clearly indicated the
effect of the liver flukes in ruminant production and its
impact to the Ethiopian economy.
