Standard Interpretation

Standard: 2009 TNI
Section: V1M5, Section


Can you please clarify what is meant by "methods tha specify colony counts such as membrane filter or plated media." Does this mean all methods that are enumeration? Or just the membrane filter and plated media methods?
Thank you!


Comparability of responses found in environmental microbiological testing is an important laboratory tool for ensuring comparability between multiple analysts or parallel counts determined in a laboratory with only a single analyst. The current language in the 2009 TNI Standard relates to the colony counts determined with membrane filter testing and plated media.
