Detection limit of microbiological analysis in breweries
Significance | Microbiological quality assurance in breweries aims at establishing the microbiological condition of the individual steps in production and filling and of goods for sale. At any rate, infection sources that may contaminate or re-contaminate beer have to be identified. Such sources have then to be eliminated and, finally, successful elimination has to be proven. This experiential report contributes to minimising the “role of happenstance” by giving due consideration to the lower detection limit of a microbiological analysis. Influences arising from the sample volume (e.g. from pipes) and from the test volume on microbiological analysis results are presented.
