Salmonella is a communicable enteric pathogen commonly found in foodborne diseases. We showed the prevalence of S. enterica serovars from domestic residents and overseas travelers. In 2004-2005 years, Weltevreden, Anatum, and Tallahassee were predominant Salmonella serovars from overseas travelers, but Enteritidis, Typhimurium, and Typhi were major Salmonella serovars from domestic residents. In order to analyze the trends of prevalence and distribution of the serovars, Salmonella surveillance with an international study is essential for the disease control and prevention.
