Case studies provide further examples and illustrations. 17-1. Indicator organisms have been used since 1892, the year Schardinger tested water for what is now called Escherichia coli, instead of testing for Salmonella typhi.It is difficult to detect S.typhi in a water supply. The presence of E coli indicates that there might have been contamination from sewage and that Salmonella or other intestinal pathogens might be present. In addition to the indicators just described, other drinking water indicators also have been used or suggested, usually as a supplement to the initial indicators. These supplemental indicators. Introduction. In microbiological testing, an "indicator organism" is defined as a marker that reflects the general microbiological condition of a food or environment (Chapin et al., 2014).In contrast, an "index organism" is a marker that reflects the possible presence of ecologically similar pathogens, suggesting a potential public health risk (Chapin et al., 2014). Common foodborne genera of the Family Enterobacteriaceae include Citrobacter, Enterobacter, Erwinia, Escherichia, Hafnia, Klebsiella, Proteus, Providencia, Salmonella, Serratia, Shigella, and Yersinia. Psychrotrophic strains of Enterobacter, Hafnia, and Serratia may grow at temperatures as low as 0C.
