Es wurde eine Querschnittsstudie durchgeführt, um die bakteriologische und physikalisch-chemische Qualität von sechs in Hawassa, Äthiopien, vertriebenen Marken von abgefülltem Wasser zu bewerten. Insgesamt wurden 105 Proben aus Abfüllanlagen, Gro - und Einzelhandelsgeschäften entnommen und auf Gesamtcoliforme (TC), thermotolerante Coliforme (TTC), E. coli, heterotrophe Keimzahl (HPC) und standardmä ige physikalisch-chemische Parameter untersucht. Die bakteriologische Analyse ergab, dass das Rohwasser der Unternehmen A, C und F zu 80-100 % mit TC und TTC kontaminiert war. Insgesamt waren 32,2 % bzw. 8,9 % der abgefüllten Wasserproben positiv für TC und TTC, während keine E. coli enthielt.
