ISO DIS 21703

Description / Abstract: This document provides microbiological test methods for enumeration and detection of aerobic mesophilic bacteria, detection of Escherichia coli and Pseudomonas aeruginosa in liquid hand dishwashing.

Microorganisms to be tested might be different from country to country according to the practices or regulations. Users can choose enumeration and/or detection methods for those microorganisms which are mentioned in this standard based on their needs.

In order to ensure product quality and safety for consumers, it is advisable to perform appropriate microbiological risk analysis so as to determine the type of the product to which this International Standard is applicable. For example, products considered to present a low microbiological risk include those with low water activity, those with extreme pH values, etc. (see ISO 29621)

Alternative microbiological methods may be substituted for the tests presented here provided that their equivalence has been demonstrated or the method has been otherwise validated.
