“…Indicator organisms may be employed to reflect the microbiological quality of foods relative to product shelf life or their safety from food borne pathogens. Microbial indicators are more often employed to assess food safety and sanitation than quality [19,20]. According to WHO [10], there was 25% diarrhea in food borne illness caused by food infected with E. coli.…”

“…(Ostrolenk et al, 1947;Gyllenberg et al, 1960;Van Donsel et al, 1967). However, these data cannot be ex-trapolated to mineral water as the chemical composition of this water and the environmental conditions largely determining the longevity of the bacteria ( Van Donsel et al, 1967;Buttiaux & Mossel, 1961) are very different from those of surface or well water.…”

Summary. We demonstrated that a washed suspension of E.coli does not subsist in Vittel mine• water more than one to four days depending on the size of the inoculum.On the other hand, P.vulgaris and especially K.pneumoniae can survive much longer in this water. Thereafter we showed that the longevity of E.coli and S.faecalis introduced into mineral water by fecal matters may be 1.5 months if the amount of feces is too small to allow multiplication of the bacteria, and 3 -4 months if the amount of feces is sufficient to allow multiplication.Our results also show that various organic products introduced into mineral water have the same protective effect as feces upon E.coli and S.faecalis, notably if they allow these bacteria to proliferate.The importance of the time interval between bottling the water and sampling for bacteriological analysis is discussed with the aim of understanding the significance of the presence or absence of test-bacteria as indicator of fecal pollution of bottled mineral water.

“…To estimate food sanitary quality, the classic approach is based on the search for not only pathogenic microorganisms but also indicator microorganisms such as fecal coliforms, whose presence indicates possible pathogens and fecal food contamination of human and/or animal origin (10,34,47). According to the International Organization for Standardization (ISO), fecal coliforms, renamed thermotolerant coliforms, are "Gram negative bacilli, not sporulated, oxidase negative, optional aerobic or anaerobic, able to multiply in presence of bile salts or other surface agents which have equivalent properties and able to ferment lactose with acid and gas production in 48 h at the temperature of 44 Ϯ 0.5°C" (30,31).…”

A 24-h direct plating method for fecal coliform enumeration with a resuscitation step (preincubation for 2 h at 37 ؎ 1°C and transfer to 44 ؎ 1°C for 22 h) using fecal coliform agar (FCA) was compared with the 24-h standardized violet red bile lactose agar (VRBL) method. FCA and VRBL have equivalent specificities and sensitivities, except for lactose-positive non-fecal coliforms such as Hafnia alvei, which could form typical colonies on FCA and VRBL. Recovery of cold-stressed Escherichia coli in mashed potatoes on FCA was about 1 log unit lower than that with VRBL. When the FCA method was compared with standard VRBL for enumeration of fecal coliforms, based on counting carried out on 170 different food samples, results were not significantly different (P > 0.05). Based on 203 typical identified colonies selected as found on VRBL and FCA, the latter medium appears to allow the enumeration of more true fecal coliforms and has higher performance in certain ways (specificity, sensitivity, and negative and positive predictive values) than VRBL. Most colonies clearly identified on both media were E. coli and H. alvei, a non-fecal coliform. Therefore, the replacement of fecal coliform enumeration by E. coli enumeration to estimate food sanitary quality should be recommended.
