Salmonella typhimurium is one of the species of Salmonella found in poultry and poultry products. Infection with Salmonella typhimurium is an important cause of morbidity and mortality in poultry. This study was undertaken to investigate the prevalence of Salmonella typimurium in poultries in Abuja metropolis. Four hundred and eighty ( 480) samples of poultry products comprising 48 samples of chicken droppings, eggs, feed and intestinal swabs respectively were collected from 10 different farms. Questionnaires were also administered on farm workers to assess the level of hygienic practices in these poultry farms. The samples were culture on Deoxycholate citrate agar (DCA) and isolates were identified biochemically, serologically and by molecular methods using polymerase chain reaction (PCR) techniques. Eighteen (3.75%) out of the 480 samples yielded Salmonellatyphimurrium. Only 3 farms showed the presence of Salmonellatyphimurium; farm 1 with 6 samples positive (1.25%); farm 2 with 5 positive x samples (1.04%) and farm 5 with 7 positive samples (1.46%). Salmonella typhimurium were isolated only from chicken droppings 15(12.5%) and from intestinal swabs 3 (2.5%). Respondents report showed that 14% of the farms cleaned their farms of droppings weekly while 86% did monthly. The presence of Salmonella typhimurium in these poultry farms poses a risk to the birds as well as to public health and so the need to improve hygiene and sanitary standards in poultry farms is therefore recommended.
