125 of commercial hen's eggs were collected at random from Assiut markets and different groceries. The egg samples were examined super ficially for bacterial contamination which may be present on shells. The mean value of total bacterial count, Coliform, faecal coliform, Enterococci and S. aureus counts were, 37x106, 3x10°, 6x102, 16x102 and /100/shell, respectively. Different isolates (117) were identified as, S. aureus, Staph. epidermidis, Micrococcus, Strept. faecalis, strept. faecium, intermediate, E.coli, Enterobacter, Citrobacter, Klebsiella ozan ae, Arizona hinshawii, Acinetobacter calcoaceticus, Pseudomonas auro genosa and Serratia.
