How to define a Contamination Control Strategy (CCS)
In Part 1 of this blog series we learned how contamination is defined and what it means to control potential contamination. In Part 2 we discussed how the EU GMP Annex 1 2020 Draft Guidance regards CCS. In Part 3 we will talk about how to define the potential root causes of contamination.
How to define the potential root causes of contamination in 3 steps:
Together, the 3 steps below define the potential root causes of contamination with the result being a comprehensive understanding of the process’ contamination vulnerabilities.
Process Mapping – Identify the risks of viable and non viable contamination
Qualitative Approach
HAACP (Hazard Analysis & Critical Control Points) – Identify the CCP including associated risk.
Note: repeat Steps 1 and 2 for all root causes identified!
Quantitative Approach
Risk Evaluation FMEA (Failure Mode & Effects Analysis) – Define the risks by their criticality to the process, and quantify the risk associated with the CCP, therefore with the specific process phase.
