“…Also, similar results were observed in Egypt by Taher and Sayed, (2011) where a incidence of 4.8% were reported. However, low prevalence was observed in the present study compared to those obtained in some localities from : Bulgaria (11.30%) (Kanchev et al, 2008), Iran (12.87%) (Radfar et al, 2005), Australia (13.6%) (Broadbent, 1972), Italy (14.6%) (Scala et al, 2015), India (20.25%) (Deka and Gaur, 1993), Nigeria (21.4%) (Dada and Belino, 1978) and (23%) 3318 A.

A total of 10696 randomly selected sheep have been collected in two slaughterhouses in the north of Algeria (El Harrach and Boufarik) to determine the prevalence of ovine cysticercosis, to find out the association between prevalence and potential risk factors as well as to assess the distribution of C. tenuicollis and C. ovis in surface’s muscles, viscera and cavities (abdominal, thoracic and pelvic) of slaughtered sheep. Sheep were native breedsand originated from different sub-districts within the municipality and its environs. All the slaughtered sheep carcasses were visually and carefully inspected. Ovine cysticercosis was found in 461 sheep (4.31%). There were Cysticercus tenuicollis and Cysticercus ovis with respectively, 2.25% and 2.06% prevalence. The prevalence of C. ovis was significantly higher (p<0.0001) in females than males while all positive for C. tenuicollissheep were male. The prevalence of the both species increased with age, and the difference was statistically significant (p<0.0001). For C. ovis, it didn’t have significant difference between season, but, the incidence of C. tenuicollis was significantly higher (p<0.0001) in autumn. All the detected cysts of C. ovis were non-viable, and were more frequently detected in the heart (51.82%) followed by diaphragm (30.77%) and esophagus (17.41%). The predominant localization of C. tenuicollis were the liver (57.71%) and the omentum (42.29%), however, no vesicle was observed in the peritoneum. This anatomical distribution of C. ovis and C. tenuicollis cysts showed a significant variation (p<0.001) in different predilection sites. The present study has revealed a non-negligible prevalence of ovine cysticercosis in the two slaughterhouses in the north of Algeria,suggesting that ovine cysticercosisis present in the north of Algeria. Appropriate control measures need to be introduced to reduce the prevalence of these parasites in sheep.

“…In our study, all the cysts detected were non-viable. Broadbent (1972) noted that 99.8% of the cysts detected were non-viable and viable cysts were found only in lambs under 12 months of age. Sheep probably have a good immune system that allows them to fight cysticercosis cysts.…”

“…The estimated sheep measles prevalence was 8.5% during the four surveillance months of 2007. However, from 2008, C. ovis levels remained less than 4.1%, which was very similar to earlier findings of levels of 4% in slaughter sheep in both Victoria and Western Australia . Significant risk factors for C. ovis condemnations include scavenging of carcases by farm dogs and failure to dispose of deadstock .…”

“…However, from 2008, C. ovis levels remained less than 4.1%, which was very similar to earlier findings of levels of 4% in slaughter sheep in both Victoria 37 and Western Australia. 42 Significant risk factors for C. ovis condemnations include scavenging of carcases by farm dogs and failure to dispose of deadstock. 41 It is not known whether this apparent recorded decrease in sheep measles cases over time is associated with targeted local control and producer extension campaigns in Tasmania or relates to inspector training, changes in recording practices or other unknown factors.…”

Reasons for the significant between-abattoir differences in recorded levels of ovine sarcosporidiosis and cysticercosis remain unknown, but may represent sampling bias, with subsets of slaughter sheep going to abattoirs with different tiers or access to markets. Further investigation into apparent differences, including epidemiological studies of properties with high lesion prevalence, comparing meat inspector diagnostic sensitivity, assessing the effect of line speed and tiers and market access in different abattoirs, may be useful.
