Use of ultraviolet radiation and hydrogen peroxide for improvement of microbial quality of tables eggs and assuring safety is under studied in India. Considering this fact in the present study, a total of 432 Table eggs were procured form local retail markets of Parbhani city and treated with UV radiation at different exposure time of 1 (UV-1), 2 (UV-2) and 4 (UV-4) minutes alone and with1.5 % H2O2 (HP) and analyzed for microbial quality of eggshell surface. Efficacy of ‘HP+UV-2’ & ‘HP+UV-4’ treatment was found to be significant (p<0.05) in reducing total viable count of eggshell surfaces whereas Staphylococcus spp. contamination was significantly (p<0.05) reduced up to 1.5 log10 cfu by use of ‘HP+UV-4’ treatment. Comparative effect of various treatments on yeast and mould counts indicated non-significant difference except for HP+UV-4. The study concluded that the combination of ‘HP+UV-4’ found to be superior than other treatment groups in enhancing microbial shell surface quality of Table eggs to safeguard the public health.
