Abstract
SUMMARY: Fifty-eight bottles of natural mineral water, taken from the point of sale, were bacteriologically examined. No coliforms orAeromonas sp.were isolated from any sample. High total bacterial counts were found particularly in the still waters. Most of the organisms isolated in the total counts were Gram-negative rods, but Gram-positive organisms were also isolated. Gram-positive cocci were further identified, some of which were known human commensals suggesting contamination of the waters prior to bottling.
