Abstract In this study the efficiency of two commercial anti-bacterial compounds comprising hydrogen peroxide and Nanosil D2 for reducing of bacterial population on egg shell surface was compared. Thus, 90 eggs were prepared and divided into 3 groups. In first group, Nanosil, in second group, hydrogen peroxide and in third group sterile water (as control) were sprayed on outer surface of egg shell. After 30 minutes, crushed egg shells were cultured. After preparation of serial dilution, Escherichia coli colonies were identified and counted according to usual bacteriological procedures. The results revealed there are no significant differences in amount of E. coli colonies between eggs exposed to Nanosil and hydrogen peroxide. The eggs exposed to Nanosil and hydrogen peroxide showed significant lower infectivity comparing to the control group. Thus, it seems that Nanosil can be used as a disinfectant of eggs.
