Standardize sampling procedures and comply with ISO 1893
Microbial surface sampling using contact plates (e.g. RODAC) is an important part of environmental monitoring in diverse industries. ISO 1893 provides some guidance on how to implement this. Two aspects are important to sample horizontal surfaces:
- The pressure/weight on the surface needs to be standardized
- The sampling time needs to be standardized to 10 seconds
Surface sampling is an important part of viable particle monitoring within the GMP Annex 1 guideline for production of sterile medicines.
