    Notes: The speed of ATP bioluminescence assays makes them very useful for assessing product quality and efficiency of sanitation at food plants. the suitability of a new method for evaluating the quality of raw milk was compared with plate count. A good correlation was obtained between the ATP method and plate count for milks with counts above 1 × 104 cfu/ml. the combination of ATP bioluminescence with preincubation procedures was investigated for predicting the shelf-life of pasteurized milk. the best correlations were obtained when milks were preincubated at 15C for 25 h or at 21C for 25 h in the presence of an inhibitor system to prevent Gram-positive bacterial growth.Hygiene monitoring using bioluminescence gave a better indication of surface cleaniness than conventional swab counts. the reasons for the discrepancies in a small percentage of cases are discussed.

    COMPARISON OF MICROBIOLOGICAL METHODS FOR MONITORING CHICKEN CARCASS QUALITY (1994)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Many methods have been developed to determine microbial levels in food products and these include ATP bioluminescence, hydrophobic grid membrane filtration (HGMF), impediometry and turbidimetry. A comparison of these techniques for detecting microbial levels in chicken carcass rinses was conducted.Only the ATP bioluminescence assay and the HGMF system showed a good correlation with plate counts (r = 0.82 and r = 0.83, respectively). The repeatability of these methods was acceptable. There was also a significant correlation between results obtained with two turbidimetric methods and HGMF as well as between HGMF and ATP bioluminescence data. However, only the ATP bioluminescence assay was able to provide results of microbial levels on a realtime basis (within 10 min). This would be beneficial for HACCP (Hazard Analysis of Critical Control Points) based programs.
