A total of 90 random samples represented by local and imported natural sheep Casing (45 of each) were collected during certain processing steps from a plant which is working in processing natural casing and implementing HACCP system at Cairo Governorate .These samples subjected to some bacteriological examination as Aerobic Plate Count (APC), Enterobacteriaceae, Coliform Count, Staphylococci count .The results revealed that imported samples showed relatively higher mean values than the local one; where APC was (5.47± 0.20,5.51± 0.18, 5.56± 0.22) log CFU/g ,Enterobacteriaceae was (1.41± 0.14 ,1.99± 0.23, 1.81± 0.27) log CFU/g, Coliform was (1.42±0.22,0.98± 0.21,0.92± 0.26) log CFU/g and Staphylococci was ( 3.16±.0.17,3.21±.0.15, 3.16±.0.12) log CFU/g for imported samples at intial Salting , Sorting, Final Salting Steps; respectively. While, APC was (5.48± 0.13,5.62± 0.14, 5.47± 0.12) log CFU/g ,Enterobacteriaceae was (1.00± 0.00 ,1.95± 0.19, 1.23± 0.12) log CFU/g, Coliform was (0.83±0.13,1.25± 0.21,0.54± 0.07) log CFU/g and Staphylococci was ( 3.09±.0.17,3.06±.0.15, 2.71±.0.16) log CFU/g for local samples at intial Salting , Sorting, Final Salting Steps; respectively.
