Isolation of salmonella from goats slaughtered at export abattoirs in Bishoftu town

Abstract

A cross-sectional study was conducted between February, 2020 and March 2020 on apparently healthy slaughtered goats at Abyssnia export abattoirs located at Bishoftu towns to estimate the prevalence of salmonellosis from goat meat by the isolation and identification conventional tests. A total of 200 samples carcass swab (60), hand swab (40), knife swab (40) and faces (60) were collected from goats slaughtered at Abyssinia export abattoir. The samples were examined for the presence of Salmonella by the conventional techniques of Selective media and biochemical tests for isolation salmonella species. From the total of 200 animals examined, 5 (2.5%) were positive of which 4 (2%) were young and 1 (0.5%) were adult. Statistically significant difference (p=0.01) in the prevalence of Salmonella was observed between the age of goats. Of the total 200 samples examined from apparently healthy slaughtered goats, 5 (2.5%) samples were Salmonella positive. Salmonella was isolated from 1.5% carcass swab, 0% hand swab, 0.5% knife swab and 0.5% faces samples. However, there was significant difference between samples (P=0.01). The results of this study showed the potential risk of goats as sources of pathogen for humans in the study area. These findings stressed the need for implementation of preventing close contact of offal and carcass during evisceration.
