Studies on Salmonella spp. and Escherichia coli Contamination in Poultry Meat Carcasses at an Automatic Slaughter house in Khartoum State . Sudan

Abstract

The aim of the study was to investigate the contamination of poultry meat In automatic slaughterhouse with Salmonella spp. and Escherichia Coli. Sixty swab samples were collected from carcasses of broiler chickens . The study covered six stages of poultry meat processing and these were hands of employees , defeathering , evisceration , after washing , after chilling , and packing . Isolation and identification of Salmonella spp. and Escherichia coli were done at each of the six stage . The highest contamination level as measured by Total Viable Counts was due to Salmonella spp. 11.11 % at defeathering , Escherichia coli at the same stage was 7.42% . While the lowest contamination level was at after chilling , there were significant difference at P-Value (P≤ 0.05) as far as the contamination is concerned at the six stages . The Salmonella spp. and Escherichia coli were predominant in slaughterhouse processing ,this will affect safety and quality of poultry meat . Right application of HACCP will greatly reduce the bacterial contamination
