Bio-fluorescent particle counting technology, a type of rapid microbiological method, uses the detection of the intrinsic fluorescence of microbial cells to enumerate bioburden levels in air or water samples, continuously. The reported unit is commonly referred to as an autofluorescence unit, which is not dependent upon growth, as is the traditional method. The following article discusses challenges encountered when implementing this modern technology, and the perspective from a consortium of four industry working groups on navigating these challenges.
