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 characteristic sequences. A data processing module reads the array to form a multispecies distribution output, and this is processed to provide trend, warning or other data. The array testing and processing sequence may involve culture multiplication, nucleic acid extraction, PCR amplification, labeling of targets and hybridization to the probe matrix array, followed by fluorescence detection and image analysis, to provide information on the presence and/or distribution of a specific group of organisms. The arrays may be configured with different species and gene sequences to effect clinical or diagnostic testing, workplace or environmental testing, and may be applied to other situations.
