Abstract

The microbial contamination of local sheep carcasses was inspected in Baghdad cityabattoir. A total of 216 samples were collected from 36 carcasses for identification of the microbial isolates and total plate count of these organisms. Samples were taken from the site of Thigh, shoulder in both sites of carcass, meat between ribs and meat of back . Each sample was divided into three replicates, and determine the chemical compositions of meat. Meat extraction samples were cultured in different diagnostic and nutrient cultures to detect bacterial contamination which represented mainly of Coliform, Staphylococcus, Salmonella  and  total counts of bacteria.

The presence of bacteria in meat at slaughterhouse indicated that unhygienic processing of meat. The results  showed differences among carcass cuts in total plate count and Staphylococcus count without significantly. while count of coliform bacteria showed significantly lowest in meat between Ribs samples (3.65+0.49 log¹⁰ cfu/mg). The average bacterial count in the meat was less than of the normal range of Central Organization for Standardization and Quality Control. Salmonella bacteria showed negative results in all samples. The results showed significant differences in ratio of protein, fat, ash and PH after 24 hours indifferent cuts of carcasses.
