Marc and Mark discuss the challenges of pharmaceutical contamination monitoring and data management in pharmaceutical facilities. They introduce a software solution called PharmaIntegrity, which combines automatic and manual data collection for a comprehensive view of environmental monitoring. Using a mold-contaminated facility as an example, they illustrate the software's ability to generate heatmaps and track contamination progression. They emphasize the importance of analyzing data from different times and areas for a complete picture, and highlight the potential for early detection of contamination.
