The use of reference materials in food microbiological laboratories


, : The use of reference materials in food microbiological laboratories. Proceedings of the 3rd World Congress on Foodborne Infections and Intoxications, Berlin, Germany, 16-19 June 1992: Volume 1: 532-535

A process for producing reference materials (RM) for use in microbiological procedures for testing food quality is described. A microbiological RM is required to: (i) contain a known number of the target microorganism(s), with the selected strain exhibiting characteristics typical of the target organism(s); (ii) remain stable over a defined period of time; and (iii) be homogeneous (the distribution of the organism(s) within the material should remain within a target range).
