Numerous studies have evaluated the antimicrobial effects of ClO2 in various fields. ClO2 has been studied as an agent for water disinfection and various other purposes (Hsu and Huang, 2015). In this study, ClO2 gas is a considerable sanitizer against Salmonella enterica on eggshells. Like this, industry related with poultry could use ClO2 gas treatment in order to reduce attached salmonellae on poultry skin. With the application of a proper concentration and exposure time, ClO2 gas exposure may be an excellent method for egg disinfection as an alternative to current methods used to sanitize eggs. Moreover, although it needs further study, ClO2 gas could be widely utilized in various food industries.
