Abstract
This study was carried out to determine Salmonella contamination of food contact surfaces and processing water in
meat, fish and poultry processing units in Sokoto State, Nigeria. A total of 200 swab (100 from abattoir and 100 from poultry
and fish markets) and 60 processing water samples (30 from abattoir and 30 from poultry and fish markets) were collected
between May to August 2015. Cultural isolation, bio-typing and sero-grouping using Salmonella Sero-Quick Group Kit
was conducted to analyse the samples. Seventy-five (75/260, 28.8 %) of the total samples were positive to Salmonella by
cultural isolation and bio-typing. Thirty (30/130; 23.1 %) of samples collected in abattoir and 45 (45/130; 34.6 %) of those
collected from poultry and fish markets were positive for Salmonella respectively. Sero-groups D+Vi (Salmonella Typhi),
B (Salmonella Paratyphi B, Salmonella Typhimurium) and C (Salmonella Paratyphi C, Salmonella Cholerae suis) were
identified as the prevailing sero-groups in this study. Sero-group D+Vi has the highest prevalence (73.3 %; 55/75) from the
positive bio-typing isolates. This study revealed the presence of contaminating and pathogenic Salmonella on food contact
surfaces and processing water in the meat retail markets, indicating there is an urgent need to improve on the hygienic status
of retail meat, poultry and fish markets.
