Evaluation of Fascioliasis, Hydatidosis, and Tuberculosis in Domestic Animals during Post-Mortem Inspection at Jijel Slaughterhouse (Algeria)

Abstract

Background: Some animal infectious diseases such as tuberculosis, hydatidosis, and fascioliasis cause public health concerns and also significant economic losses. The goal of this study was to assess the rate of fascioliasis, hydatidosis, and tuberculosis in domestic animals during post-mortem inspection at Jijel slaughterhouse, North-Eastern Algeria.
 Methods: The present study was carried out from March 2017 to February 2018, on 6 520 animals slaughtered at Jijel slaughterhouse. It was based on post-mortem inspection of livers and lungs by visual inspection, palpation, and incision. The statistical analysis was performed using open source software R 2017 and Microsoft Office Excel software.
 Results: The prevalence rate of fascioliasis (6.9%) was significantly (p<0.001) higher than that of hydatidosis (4.8%) and tuberculosis (1.0%). Regarding all three studied diseases in the slathered animal, the prevalence rate of the diseases in cattle was significantly higher than one in sheep and goats. Three peaks in the rate of studied diseases were recorded during March to May 2017, which corresponds to spring.
 Conclusion: Considerable prevalence rate of fascioliasis, tuberculosis, and hydatidosis in domestic animals slaughtered at the Jijel slaughterhouse seems to be an important indicator of lack of inspection, preventive, and curative treatments of animals in this region.

Reasons for the seizure of cattle meat, their prevalence, and socio-economic impact in the Cotonou slaughterhouse

“…In our study, the most frequent reason for seizure was tuberculosis -317 out of 844 (37.56%). The economic importance and public health significance of tuberculosis have been established in many countries [12,13,14]. Similar to the result obtained by Awah-Ndukum et al [15] in Yaoundé-Cameroon, tuberculosis was the main cause of whole carcass condemnation.…”

Pathological Findings in Cattle Slaughtered in Northeastern Algeria and Associated Risk Factors

“…According to Bentounsi (2001) [20], the nature of the soil (clayey, heavy and smooth soils which favor the development of Lymnaea), temperature (no development if the temperature is below 10 • C) and humidity can be considered as favoring causes. In addition, according to Hamiroune et al (2020) [21], The Jijel region is very humid. It is very rich in water resources: five large dams, three large natural lakes and numerous streams; so many indicators of the infestation.…”

“…These results can be explained by several factors, in particular, during the fattening period, in the majority of cases, the animals (mainly the males) prepared for slaughter, are raised in an intensive system. In addition, depending on the ability of breeders and practicing veterinarians who monitor the breeding, these animals are treated with antiparasitics against parasites and with antibiotics against infectious diseases, as well as other drugs like vitamins, which leads to a decrease in the number of cases of parasitized organs despite the presence of humidity in the external environment [ 21 ]. Besides, in the region of Jijel, sheep farms, especially local breeds (mainly females) are reared extensively (unlike other breeds) which promotes the transmission of various infectious diseases in the case of the presence of survival factors and the development of contamination agents.…”

Occurrence and genetic characterization of Echinococcus granulosus sensu lato from domestic animals in Central Iran

“…The echinococcosis has been reported in Australia, northern and eastern Africa, Central Asia, and some Mediterranean countries [6,7]. Additionally, infection in livestock and ruminants has been described in different parts of Iran [8].…”
