Fluorescence cytometry for the rapid analysis of food microorganisms

  • A. C. Pinder
  • S. Gatley


A key factor in the implementation of active product quality management in the food industry is the delay associated with microbiological analysis. Incoming raw materials need to be inspected before acceptance, production processes such as fermenters need to be continuously monitored, final products need to be tested for quality, and environmental cleaning procedures need to be assessed for effectiveness. Any delay in identifying batch failure during production, due for example to contamination or uncontrolled changes in manufacturing conditions, may result in the loss of expensive raw materials and a consequent reduction in plant efficiency. Microbiological data on the quality of the final product (particularly if it is a short-life product) may not be available until several days after that product has been released on to the market; a bad report will mean product recall, with all its associated cost implications, and will lead to a reduction in customer confidence.
