The following study describes a methodology to establish, control, and characterize an aerosolized bioburden within a test chamber and determine the settling rate of the bioburden.
Pharmaceutical and nutritional package integrity is often studied by incidental contamination, via immersion or aerosol microbiological challenge tests. Aerosol tests rely upon microorganisms settling from the atmosphere onto critical surfaces. Maintenance of a contaminated atmosphere is necessary to create the conditions that will cause a constant settling rate of the test microorganisms. Both parameters--maintenance of bioburden and duration of exposure--have to be monitored and controlled. It is important to understand the limitations of aerosol tests where the microbial contamination conditions are not maintained over the duration of the test. The following study describes a methodology to establish, control, and characterize an aerosolized bioburden within a test chamber and determine the settling rate of the bioburden. The intention of this paper is to stimulate the necessary discussion for the establishment of the standard criteria for all aerosol tests to generate comparable and reproducible data.
