The results of this model are presented to the user in the form of reports (e.g., in PDF format), allowing the user to study the, quantitative and reproducible detection of trace contamination and that it can be performed efficiently and economically under routine conditions. These requirements are fulfilled optimally by the membrane filter method. The principle of this method is based on the concentration of microorganisms from.

The quantitative assessment of exposures to microorganisms through food intake is an important part of the quantitative risk assessment made possible by the application of newly developed simulation approaches applicable to high performance computers. Quantitative reverse transcription polymerase chain reaction (q-RT-PCR) is a more sensitive technique that detects low copy number RNA and can be applied to detect, e.g. enteric viruses and viable microorganisms in water, and measure specific gene expression. There is, however, a need to standardise qPCR protocols if this technique is to be used as an analytical diagnostic tool for routine …
