ORIGINAL_ARTICLE 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. https://macvetrev.mk/Files/Article/2019/10.1515/macvetrev-2017-0011/macvetrev-2017-0011.pdf 2017-03-15T09:00:00 59 65 10.2478/macvetrev-2017-0011 Salmonella meat contact surface sero-group abattoir Nigeria Olufemi Oludayo Faleke false 1 Department of Veterinary Public Health and Preventive Medicine, Faculty of Veterinary Medicine Usmanu Danfodiyo University, Sokoto State, Nigeria AUTHOR Kelvin Olatimilehin Jolayemi false 2 Department of Veterinary Public Health and Preventive Medicine, Faculty of Veterinary Medicine Usmanu Danfodiyo University, Sokoto State, Nigeria AUTHOR Yvvone Ogah Igoh false 3 Department of Veterinary Public Health and Preventive Medicine, Faculty of Veterinary Medicine Usmanu Danfodiyo University, Sokoto State, Nigeria AUTHOR Abdurrahman Hassan Jibril jibrilah50@yahoo.com false 4 Department of Veterinary Public Health and Preventive Medicine, Faculty of Veterinary Medicine Usmanu Danfodiyo University, Sokoto State, Nigeria LEAD_AUTHOR Julius Olaniyi Ayedun false 5 Department of Veterinary Public Health and Preventive Medicine, Faculty of Veterinary Medicine University of Ilorin, Kwara State Nigeria AUTHOR Vehlner M, Mechanisms of resistance to quinolones and epidemiological significance of Salmonella sppActa Veterinaria-Beograd 2016; 66: 2147-159. 1 10.1515/acve-2016-0013 Javadi A, Safarmashaei S, Ghadimi R, Study on Salmonella contamination in poultry lean meat and meat with skin in Tabriz slaughter housesAfrican Journal of Biotechnology 2011; 13: 1181-184. 2 10.5897/AJB11.3500 Panisello PJ, Rooney R, Quantick PC, Stanwell-Smith R, Application of food-borne disease outbreak data in the development and maintenance of HACCP systemsInt J Food Microbiol 2000; 59: 221-234. 3 10.1016/S0168-1605(00)00376-7 Bean NH, Goulding JS, Daniels MT, Angulo FJ, Surveillance for food born disease outbreaks-United States 1988-1992J.
