Prevalence of Bacterial Contamination of Public Health Concern on Bovine Carcasses at Khartoum state

Abstract

The present study was carried out in two slaughter houses in Khartoum State to asses the meat hygiene practice and to : look after these points 1- Identify probable pathogenic Bacteria in fresh meat at slaughterhouse. 2- Determine the source of contamination of beef in slaughterhouses. Critical control points were selected in cattle slaughter line. They include working, tools such as knife, hands of the workers and various parts of the carcass as rumb, brisket and flank at a skinning, evisceration and after washing. They were chosen to collect samples because these locations are most likely to become contaminated during slaughtering and . dressing procedures After laboratory investigation ( Isolation and Identification ) by standard bacteriological techniques for one hundred and thirty samples were tested to isolate and identify the types and species of aerobic bacteria . Both . Gram Negative and Gram Positive Bacteria were isolated The Gram- positive were Micrococcus Luteus, M.Roseus , Staphylococcus areus, S.Heamolyticus, S.ebidermids, . S.Closii, Bacilus cereus, B.Laterosporus and B.Alvei 14: The Gram Negative bacteria were Escherichia Coli, Klebsiella Pnenumonia, Proteus Valgaris, Pseudomonus Aregnosa and Pasteurella . Multocida The bacteriological examination of collected swabs revealed the highest contaminations in the point of washing in all . sites
