Abstract: A testing system useful for food products employs a multispecies testing array to test for presence or amount of a plurality of organisms in a sample by detecting plural characteristic sequences for each of plural organisms to form a multispecies distribution output or microbial profile, and this is processed or used in conjunction with data mining or other processing to provide trend, warning or other data. The processor correlates and stores information relating to taste, smell, texture, processing conditions, quality or source of a component or ingredient, potential pathogenicity or other factor, with correlations on a multidimensional space yielding new preconditions or warning indications, and providing a mechanism for specialization of the species distribution data for specific products, as well as for incorporation or development of process changes and company trade secrets.
