L. Khaitsa and Dawn Doetkott North Dakota State University USA 1. Introduction Infections with nontyphoid Salmonella enterica serovars represent an important public health problem worldwide Zhao et al. 2003 and an economic burden in many parts of the world today Gomez et al 1997 Vugia et al 2004 . In the United States US Salmonella is the second most common identifiable cause of illness and the leading cause of hospitalizations and deaths due to food-borne bacterial infection Mead et al 1999 . Each year 31 major known pathogens acquired in the US caused an estimated 9.4 million episodes of foodborne illness Scallan et al 2011 and an estimated 38.4 million episodes of domestically acquired foodborne illness were caused by unspecified agents resulting in 71 878 hospitalizations and 1 686 deaths Scallan et al 2011 .
