Microbiological environmental monitoring
Microbiological environmental monitoring describes the microbiological testing undertaken in order to detect changing trends of microbial counts and micro-flora growth in critical or controllled environments areas like cleanrooms, laminar flow hoods, biological safety hoods, isolators, intravenous compounding areas and sterile packaging.
The results obtained provide information about the performance of heating, ventilation, the physical construction, air-conditioning system, gowning practices, equipment, personal cleanliness and cleaning operations.
Environmental monitoring methods
- Water sampling
- Active air sampling
- Passive air sampling
- Surface monitoring with contact plates (RODAC) or swabbing method
Sampling locations
The sampling locations shoud be based on risk of microbiological contamination. They also should be clustered around areas where product or components are exposed e.g.
- Where aseptic connections are made
- Where there are high levels of operator activity
- At filling heads on filling lines
- Stopper bowls
Frequently asked questions
We perform environmental monitoring on location. In addition, we also provide training to carry out this yourself.
It is important that the plates are clearly coded (at the bottom). The plates can be stacked per 10 pieces and by means of tape to be glued together. Make sure that the plates are then protected in the box using, for example, bubble wrap.
