Define the problem

VanTsteri’s technical article describes contamination control as a coordinated approach to identifying microorganisms, locating contamination and evaluating whether corrective measures remain effective. A single satisfactory monitoring result does not establish the absence of contamination elsewhere.

Investigate the system

The proposed review combines historical air, surface, personnel, water and product monitoring with organism identification. Inspection and sampling consider material transfer, ventilation, building joints, moisture, equipment, pipework and water systems. Sampling locations should test a plausible contamination pathway rather than simply increase the number of samples.

Choose a targeted response

The source discusses cleaning, HVAC treatment, moisture and building repairs, biofilm control, water-system treatment and operational improvements. VHP decontamination is one possible measure; selection depends on the organism, location, material compatibility and verification requirements.

Verify and maintain control

The article recommends post-treatment checks, process records and continued trend review, with findings incorporated into deviation investigations and corrective actions. This technical overview provides no single customer-project outcome or universal treatment cycle.
