Abstract

Introduction: Salmonella is one of the most significant enteric pathogen from food safety point of view in which it is classified among the major cause of food borne illnesses.

 

Objective: To determine the prevalence of Salmonella in slaughtered sheep and to identify underlying serogroups from slaughtered sheep at Addis Ababa municipal abattoir, Ethiopia.

 

Methods: A cross-sectional study was conducted to identify salmonella serogroups. Tissue samples; liver, abomasums and mesenteric lymph node were collected aseptically using sterile scalpel blade in a sterile plastic bag. Isolation and identification of Salmonella was performed following the techniques recommended by the International Organization for Standardization 6579. Prevalence was calculated and serotyping was done using rapid slide agglutination test.

 

Results: Of 50 animals examined, one or more of the samples were Salmonella positive in 8 (5.33%) of the animals and from a total of tissue samples examined, 9 (6%) were Salmonella positive. Of the nine Salmonella isolates, three different serogroups were identified of which serogroup B (O4) was predominant (77.8%) followed by Serogroup C2 (O8) (11.1%) and Serogroup D (O9) (11.1%).

 

Conclusion: Salmonella was widespread in tissue samples of slaughtered sheep carcasses in the Addis Ababa abattoir. Sources of pathogens in food animals need to be investigated and further study of salmonella and other enteric pathogens in the public food chain is recommended. Also their food safety implication has to be further evaluated.
