Abstract :In the present cross-sectional study, eggs collected from retail outlets were analyzed for physicochemical and microbial quality. Comparisons were made between ?sanitized? insert ignore into journalissuearticles values(cleaned, sanitized, and retailed after packaging); and ?unsanitized? insert ignore into journalissuearticles values(not subjected to cleaning, sanitization, and packaging); retail table eggs that originated from ?commercial? and ?backyard? insert ignore into journalissuearticles values(eggs retailed loose without any cleaning, sanitization, or packaging); farms. A total of 1120 eggs collected from retail markets were analyzed for physicochemical insert ignore into journalissuearticles values(weight, shell thickness, shape, yolk index, albumen index, Haugh unit, color, and pH); and microbial insert ignore into journalissuearticles values(total viable count, and yeast and mold counts); characteristics. Eggs collected from retail markets were found to significantly differ with respect to weight, shell thickness, yolk index, albumen index, Haugh unit, yolk color, and total viable counts insert ignore into journalissuearticles values(P < 0.01);, but not shape index, pH, or yeast and mold counts. Discriminant analysis corroborated the categorization of table eggs and results of the present study showed differentiation of origin of table eggs based on physicochemical characteristics whereby processed eggs possessed better microbial quality attributes than unprocessed and backyard eggs. Processing of table eggs encompassing hygienic handling, cold storage, and treatment of eggs would deliver wholesome eggs to the consumers through the retail table egg supply chain.
