This practical course will first present the basic methodology of evaluating the Environmental Monitoring (EM) data using elementary Statistical Process Control (SPC) tools as well as empirical approaches to set microbial control limits for clean rooms. This course will address  the following issues:

  • Overview of controlled rooms classifications, elements of an EM program and present EU and FDA regulations including the recent ISO 14664 changes
  • How to organize and present an abundant amount of microbial data in meaningful Graphs
  • How to draw useful Control Charts with this data, using the software program Minitab© 19
  • To understand how action and alert control limits are set
  • How to demonstrate that the environmental microbial monitoring process is under a state of control
  • How to calculate and plot the newly proposed Contamination Recovery Rates in USP Chapter <1116>
  • How to detect a trend in the environmental microbial monitoring process
  • How to apply risk assessment in investigations

All above issues will be demonstrated on examples and case studies of microbial counts generated in controlled rooms of manufacturing facilities of sterile products.

Please note that a laptop is needed for the practical exercises.  Also,  the “Minitab 19” software must be installed on this computer to solve exercises and generate control charts. You can download a  free 30 days trial version of this software here: https://www.minitab.com/en-us/downloads/


Regulatory agencies require from manufacturing companies of pharmaceuticals and biopharmaceuticals, particularly of sterile drug products, to maintain an environmental monitoring program, whereby particulates as well as microorganisms in either air samples (active and passive sampling) or in surfaces (contact plates) are routinely tested and monitored.

Thus, a multitude of environmental microbial data is generated on a routine basis and it is recorded in a manner permitting trend evaluation. But collecting EM data is only the first challenge. The following challenge for the responsible person in quality is charting, analyzing data, setting action and alert limits, interpreting the overall monitoring process behaviour, detecting a trend or shift in contamination levels, monitoring excursion rates and contamination recovery rates, while conducting an ongoing risk analysis. According to the recent revision of EU Annex 1 (Dec. 2017), results from monitoring should be considered when reviewing batch documentation for finished product 1638 release.   Therefore, this course is aimed at providing empirical tools for charting and trending EM data.
