Abstract: Four hundred and fifty-seven (457) clinically healthy swine slaughtered in four abattoirs located in Umuahia area of Abia State of Nigeria were examined for the prevalence of Salmonella sp. in samples collected from spleen, small intestine, liver, lungs and lymph nodes. Swab samples were also collected from the surfaces of slaughtering tables, wash hand basins, butchering knives, workers hands and holden pens. Product samples collected from slaughtering house showed the presence of Salmonella sp. in spleen (4/40, 10.0%), small intestine (9/40, 22.5%). Liver (5/40, 12.5%), lungs (3/40, 7.5%) and lymph nodes (16/40, 40.0%). Salmonella sp. were recovered from slaughtering tables (3/15, 20.0%), wash hand basins (4/15, 26.7%), butchering knife (2/13, 15.4%), workers hands (4/15, 26.7%), holden pens (3/15, 20.0%). These samples were cultured for the presence of Salmonella sp. Simple descriptive statistics and analysis of variance were used to analyze the data collected. Although clinical Salmonellosis was not detected in the study herd, multiple serotypes of Salmonella were found causing endemic infection in the study herd. The most frequently detected species was Salmonella cholereasuis and it was resistant to all the antibiotic used in sensitivity testing except polymyxin B. This result showed the necessity for adopting more effective hygienic measures in the abattoir environment and equipment to reduce their role in the spread of Salmonella. This work will be relevant to abattoir and health workers, to show them the need to maintain good hygienic condition in abattoir environment.
