This workshop will show you the current regulatory developments in relevant guideline documents e.g. Ph Eur 5.1.2. USP <1229.8> or <1035> regarding Biological Indicators (BI) and practical experiences of industrial experts and BI manufacturers on validation of processes, evaluating BI resistance and more.
Furthermore, you will get the possibility to discuss the challenges in the use of BI with speakers and colleagues during the presentation and the following panel discussion.


Manufacturers of sterile medicinal products as well as producers of medical devices should provide safe and microbiological unobjectionable products. Therefore, they have to validate their processes for sterilisation, for autoclaving and for room gassing and fogging. This needs a multidisciplinary team work but additionally suitable biological indicators USP <1035> defines BI as a characterized preparation of a specific microorganism that provides a defined and stable resistance to a specific sterilisation process which will be used in the performance qualification of the sterilisation equipment as well as in the development and establishment of a stable, validated sterilisation processes.

Target Group

Microbiologists from pharmaceutical and biopharmaceutical Industry
Manufacturer of medical devices
Responsible QC/QA staff
Experts from contract laboratories
Manufacturer and suppliers of BI
Responsible Authorities
