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.
In order to assess the epidemiological situation of certain infectious and parasitic diseases of ruminants, a study was carried out in the central abattoir of Jijel on 625 animals (511 cattle, 74 sheep and 40 goats).The results showed that the overall organ contamination rate by the pathologies studied was 17.12% with a higher prevalence rate for fasciolosis (12.32%) compared to other pathologies. In addition, the lungs are contaminated with abscess and hydatidosis (3.04% and 0.48%, respectively), whereas the liver is mainly affected by fasciolosis, abscess and hydatidosis (12.32%, 0.64% and 0.48%), respectively) and the kidneys are affected only by cysts (0.16%). In parallel, the liver is more contaminated (13.44%) compared to the lungs (3.52%) and the kidneys (0.16%). In addition, with the exception of two weak positive correlations between hydatidosis and temperature (r = +0.01689, R2 = +0.00029) and between abscesses and precipitation (r = +0.27335, R2 = +0.07472), other high positive and negative correlations were observed between the rest of the pathologies and mean values of temperature and precipitation. Therefore, it is necessary to implement an extension program of all stakeholders in the industry in order to avoid significant economic losses and preserve consumer health.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
