Why do we take interval samples when
performing an “Active Air Sampling” regime?
Should we microbially monitor over an entire
production run to gain a more reliable
understanding of our critical areas?

• Continuous Particle Monitoring = 16m3 0.02 % Air
• Surface Monitoring;
–10 Contact Plates = 0.0250m2 = 0.417 % Surface*
–10 Swabs = 0.0250m2 = 0.417 % Surface
• Based upon the footprint of the filling machine area within the RABS. Note: the actual total surface area would be

Bottom Line on Current Growth Based Methods
• Only a small fraction of air and surfaces influencing
product quality can be tested
• Monitoring techniques have low recovery efficiency
• A limited range of organisms can be isolated using
common media and incubation conditions
• A positive isolate is a significant event
• A negative result may be misleading

Annex 1 of the GMP Guide to the Manufacture of Sterile Medicinal Products (the “Orange Guide”) is changing
the way environmental monitoring of viable organisms performed from routine sampling to continuous
monitoring.
9.27 Continuous monitoringin grade A and B areas should be undertaken for the full duration of critical processing,
including equipment(aseptic setup) assemblyand filling operations (i.e., an understanding of function and interactions of
each clean area). The monitoring should beperformed in such a way that all interventions, transientevents and any
system deterioration would becaptured and any riskcaused by interventions of themonitoringoperations is avoided.
9.28 Rapid microbial monitoring methods maybe adopted after validation as long as they are demonstrated to be at least
equivalent to theestablished methodology.
9.33 If microorganisms aredetected in a gradeA or B zone, they should beidentified to species level and theimpact of
such microorganismson product quality(for each batch implicated) and state of controlshould be evaluated.
Consideration mayalso begiven to theidentification of gradeC and Dcontaminantsand therequirements should be
defined in thecontaminationcontrol strategy.
In addition, ISO 14698 specifies some more air sampler specific criteria for active air sampling:
• Must entrap particles down to 1µm
• Sample at least 1m³
• Operate within 1 foot of critical area
• Settle plates can be used for up to 4 hours
As monitoring was not required throughout the process,
sampling was usually performed before the start and after
the end of a process. This was seen as ‘down time’ in the
process which lead to an array of rapid cubic metre air
samplers becoming available. These are samplers not
monitors!

Settle Plates “count” the number of vegetative
microbial particles that are heavy enough to
displace from the air onto a surface, in a 4 hour
period.
• What is that telling us?
• Is that enough information?
• Smaller particles?
