The addition of chelating agent to drinking‐water samples reduces die‐off, due to the toxic effect of metal ions, of bacteria such as Aeromonas. The use of ethylenediaminetetraaceticacid (EDTA) is undesirable since it is a highly persistent chemical which contributes to environmental pollution. This study shows that the less persistent nitrilotriaceticacid (NTA) is a suitable alternative. No significant differences ( P < 0.001) were detected between EDTA and NTA in protecting bacteria.
