ISO 11133   Microbiology of food, animal feed and water - Preparation, production, storage and performance testing of culture media

NEN 6603    Environment and food – Internal quality control by the use of control charts with chemical and microbiological analyses

Results from the detection method (present or absent) as well as the results of counts on agar plates can be plotted in the BiosistoChart according to NEN 6603.

Regulation 2073/2005 lays down microbiological criteria for various combinations of food commodities and microorganisms, their toxins or metabolites.
