Observed residues and the response to them put cleaning effectiveness and product-impact assessment in focus.
What happened?
FDA reported residues in manufacturing areas despite cleaning records. Its letter also questioned whether the proposed cleaning-validation response adequately addressed products already distributed.
EDITORIAL INTERPRETATION
Why does it matter?
Execution records and physical evidence answer different questions. A completed record cannot establish that the recorded procedure achieved its purpose.
Key points
- Compare recorded cleaning with observed equipment condition.
- Evaluate affected products as well as future procedures.
- Review worst-case conditions and hold times.
Practical impact
Discussion prompt: during a programme review, follow one equipment item from its cleaning record to inspection evidence, deviation decisions and any product-impact assessment.
