RESUMEN
Adopting emerging microbiological methods is often desirable because it enables more advantageous, real-time monitoring practices. However, when the newer method measures contamination based on a different detection principle and provides results that are based on different units of measure, a paradigm shift is necessary. That shift can be one of the most difficult challenges in any such project and requires careful consideration. In this article, we explore the challenges presented by the bio-fluorescent particle counting (BFPC) technology, when considering that the traditional colony-forming unit (CFU) is the gold standard that any change is measured against. We examine why attempts to correlate newer units of measure used by biofluorescent particle counters, namely the auto-fluorescent units (AFUs), to the traditional CFUs are not necessarily appropriate. The article explores in depth why there is no consistent correlation factor between the two units of measure, and why that should not be a barrier to fully leveraging, implementing, and using such modern technologies in routine monitoring.

The Process and Environmental Monitoring Methods Working Group, composed of members from industry and instrument manufacturers, met with the FDA Emerging Technology Team to discuss bio-fluorescent particle counting technology, a type of rapid microbiological method. This is a summary of the meeting including submitted questions and answers, and the Process and Environmental Monitoring Methods Working Group's understanding of the FDA Emerging Technology Team's points made.
