Abstract

Microbiological reference materials comprise capsules of artificially contaminated spray dried milk in gelatin. The contamination is carried out with a well characterised pure culture of a known bacterial species which is selected for properties relevant to the process of analytical quality control. This report describes the statistical analysis of certification studies for microbiological reference materials. Two types of reference materials are distinguished on the basis of their contamination level: high level and low level capsules. The statistical distribution of bacteria is discussed and the choice of alternative models is examined.
