123 - Indoor Air Bioaerosol Sampling from Building according NIOSH
This Application Note reports the original method from the technical paper 0800 published on 1998 by NIOSH USA (NATIONAL INSTITUTE FOR OCCUPATIONAL SAFETY AND HEALTH). After 20 years the method is still a valid and well done document. The new generation of air samplers simpli es the reported sampling process.

The microbiological environmental monitoring data is part of a continuum. Periodic analyses of environmental data should be formally prepared, reviewed by microbiological QA and presented for informational purposers by the production and general personnel responsible for speci c areas, operations and products.

It has been recommended that food processing plants adopt air monitoring programs to detect possible contamination sources in their regular HACCP program. Juice, ready-to-eat foods, pasta, meat, dairy and other food processing facilities have been advised to establish a system for weekly air monitoring. Air sampling of various areas (finished product, protein, fresh produce areas, etc.) yield information as to possible microbial contamination. That is to say, knowing the microbial population, number of colony forming units per cubic meter of air (CFU/m3) of a given area can be predictive of possible food contamination possibilities, e.g., yeast, molds, and pathogens.

The microbiological efficiency of the filters used in buildings is an essential parameter that should be regularly monitored to be sure that the contamination is under control. This Application Note reports a simple method used at 3M Development Laboratory in St. Paul, Minnesota, USA to measure the filter efficiency for fungi of industrial air handlers. The test can help to determine Indoor Air Quality in office buildings.
