[Literature survey of Salmonella contamination in eggs and egg products in the world].

Salmonella species are common bacterial pathogens associated with human gastroenteritis worldwide. In Japan, salmonellosis is one of the main food-borne bacterial illnesses and, especially, Salmonella Enteritidis infections have been strongly associated with the consumption of eggs and egg-containing foods. In this study, we performed the literature survey of Salmonella contamination in shell eggs and liquid eggs worldwide for comparing the prevalence among the countries and summarized in the tables. This survey clarified that one out of several thousands of retail shell eggs were contaminated with Salmonella spp. in Japan and the prevalence of Salmonella in retail shell eggs were higher in some countries. This paper is useful for providing referable data on Salmonella contamination in shell eggs and liquid eggs in Japan, especially for researchers of other countries.
