Bioburden excursion before filtration during aseptic filling – containment CAPA failure

The first indication of a potential issue might be unanticipated bioburden counts from routine environmental monitoring. In this scenario, the bioburden levels in the critical zones circumscribing the aseptic filling…

Cross-contamination detected post-release during media fill – containment CAPA failure

The first indication of a problem surfaced during the media fill process, apparent through unexpected colony counts in several media fill samples taken from a batch intended for aseptic processing.…

Bioburden excursion before filtration during cleaning verification – containment CAPA failure

The investigation began after the quality control team detected alarming results during the routine cleaning verification of a bioreactor system. The tests indicated a bioburden count exceeding the established acceptable…

Media fill deviation not escalated during cleaning verification – patient safety risk case study

The first indication of an issue arose during routine quality control checks when personnel identified discrepancies in the media fill results. A discrepancy was noted in the number of positive…

Unvalidated aseptic intervention during cleaning verification – containment CAPA failure

The initial signals indicating a potential issue with cleaning verification procedures were noted during routine monitoring of environmental control parameters. These included an unexpected increase in microbial counts in critical…

Unvalidated aseptic intervention during media fill – patient safety risk case study

The first indication of the unvalidated aseptic intervention during the media fill process emerged when microbiological testing results from a batch of media were found to be non-compliant. Specifically, there…

Contamination source misidentified during media fill – patient safety risk case study

The first indication of potential contamination during the media fill came from quality control results that showed unexpected microbial growth during routine sterility testing. The specific signals included:Click to read…

Media fill deviation not escalated during investigation – regulatory enforcement outcome

The initial detection of the media fill deviation occurred during routine monitoring of the aseptic processing area. Operators observed discrepancies in the expected sterility outcomes during media fill tests, which…

Unvalidated aseptic intervention during media fill – containment CAPA failure

The initial signs of an unvalidated aseptic intervention became apparent during a routine audit of the aseptic processing area. Operators noted abnormal readings in environmental monitoring data, specifically an increase…

Sterility test failure misclassified during aseptic filling – containment CAPA failure

The initial clue that something was amiss arose when routine sterility tests on product batches following aseptic filling began to show inconsistent results. The sterility tests, if not classified accurately,…

Cross-contamination detected post-release during aseptic filling – patient safety risk case study

In the hours following the release of a sterile product batch, the quality control (QC) team identified an unexpected discrepancy during post-release sterility testing. Instead of the expected absence of…

Bioburden excursion before filtration during aseptic filling – regulatory enforcement outcome

The initial signal of the bioburden excursion was observed during routine QC testing of the bioburden levels in the product solution prior to its transfer for filtration. Samples from the…
