Microbiological evaluation of edible bovine by-products (intestine, lung, rumen meat, head flesh, heart, tongue, kidney and liver) commonly consumed in Assiut city, Egypt were determined by enumerating total viable bacterial count (TVBC), total enterobacteriacae count, yeast and mold contaminants and determine the presence of Salmonella spp. and E. coli O157:H7 organisms. | Int.J.Curr.Microbiol.App.Sci 2018 7 1 3449-3458 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 7 Number 01 2018 Journal homepage http www.ijcmas.com Original Research Article https doi.org 10.20546 ijcmas.2018.701.406 Microbiological Evaluation of Some Edible Bovine By-products A.M.

The obtained results showed that the mean TVBC of intestine lung rumen meat head flesh heart tongue kidney and liver were 9x106 14x106 6x107 8x107 7x106 9x106 7x106 and 5x106 cfu g respectively. While the mean enterobacteriacae count of intestine lung rumen meat head flesh heart tongue kidney and liver were 3x106 3 x106 3x107 4x106 7x105 3x106 3x106 and 3x106 cfu g respectively. Furthermore the mean total fungal count of intestine lung rumen meat head flesh heart tongue kidney and liver were 3x104 8x104 2x104 6x104 1x104 7x104 9x105 and 8x104 cfu g respectively. Two S. enteritidis could be isolated from intestine and lung samples. One isolate of S. typhimurium was detected in intestinal sample. E. coli 157 H7 contamination was found in intestine lung rumen meat and head flesh respectively. The results of this study show that edible bovine by-products are crosscontaminated by E. coli 0157 H7 S. enteritidis and S. typhimurium and thus may pose
