Key Takeaways:
- A risk-based approach links rinse analysis and visual checks to surface cleanliness.
- The FDA’s validation model ensures structured cleaning process design and verification.
- Controlled studies define residue limits using light intensity, angle and variability.
- TOC and conductivity testing confirm surface cleanliness and cleaning effectiveness.
- Continuous monitoring reduces testing while ensuring compliance and product safety.
STERIS experts, E. Rivera and P. Lopolito, have written "Evaluating Surface Cleanliness Using a Risk-Based Approach" BioPharm International 30 (11) 2017. This article talks about rinse sample analysis or visual inspection that can be correlated to surface cleanliness to replace surface sampling.
