New Service: A New Approach to Evaluate Probiotic Cleaners
Probiotic cleaners are becoming increasingly important in modern hygiene concepts. With our new service, we now offer an innovative, practical testing approach that is specifically tailored to the special characteristics of microbial cleaning formulations. The method is based on the targeted further development of established testing procedures and enables a realistic assessment of cleaning performance and long-term effects. This allows probiotic and conventional cleaning agents to be compared under identical conditions and evaluated on a sound basis. Manufacturers and developers thus obtain a reliable basis for comprehensively testing and further developing the performance of probiotic products. If you are interested or have any questions, please do not hesitate to contact us - we will be happy to advise you individually.

News from the expert groups - Our engagement continues
In recent time there were several meetings of the CEN/TC 216 were Dr. Florian H. H. Brill represented our institute. Should you have any questions or require advice on the following topics, we are of course happy to assist you! The WG 3 led by Dr. Michele Cavalleri met in Milano in October 2025. The group drove several projects forward and asked WG 1 and WG 5 if they could integrate their project on a method for surface disinfection with mechanical action in the existing work mainly on the EN 16615 in WG 1. Subsequently, the WG 1 decided that they support the idea and ask the plenary meeting to open a new TC horizontal Task Force “Surface Disinfection with Mechanical Action” under the WG 5. The WG 5 in their meeting in December supported this idea. The plenary meeting in February 2026 will decide on that. This would drive our culture of reducing the complexity of the standards as no separate standard or standards would be published in WG 3 or 2 and their applications would be included in the EN 16615. In addition, a new initiative was started in WG 3 for algicidal testing with a first draft. Our Hydrotox team in Freiburg will put their expertise in the corresponding project group. Also, the WG 3 is moving forward to revise the EN 13704 and is intending a ring trial. Also a revision of EN 17658 was discussed and a project group was formed where our expert Dr. Britta Brands is part of. The WG 1 meeting led by convenor Professor Katrin Steinhauer took place in November as an online meeting. The virucidal 4-field test will go to the next step and CEN-Enquiry was started. Dr. Dajana Paulmann from our team in Bremen is in the project group and supporting the development. The EN 1500 is due for revision and the WG 1 decided to form a project group first discussing the areas, where changes may be useful. Dr. Brill will be part of the project group. The new version of EN 14476 was just published and the group decided to go for an amendment to include the changes resulting from work in the WG 5 Task Force Replacement of Poliovirus which Dr. Florian H. H. Brill is leading. This task force where also Dr. Britta Becker and Dr. Dajana Paulmann from our virus lab are members worked on alternative viruses to Poliovirus which should be eradicated from the planet based on a WHO initiative. There were several meetings and a large round robin test comparing polio to Coxsackie virus and EMCV. A decision is prepared for the plenary meeting in February from this group. The WG 5 meeting with the convenor Dr. Florian H. H. Brill took place in December in Berlin. In addition to the Task Force Replacement of Poliovirus the EN 14885 moved forward into the Enquiry phase as the MDR harmonization topic was solved. The harmonization and standardization task force started their work and Dr. Jürgen Gebel took the lead on revising the EN 12353 which is another major step for simplification. The EN 12353 will in future include the preparation of the strains for testing, so that this subsequently can be removed from all the other standard which will make them simpler and easier to merge into the new 1 test principle 1 standard direction. In addition, the biofilm task force which was a bit quiet will move forward now and drafting the first standards. The new task force structure is very efficient and the Task Forces Ring Trials, UV-Disinfection, Airborne-Disinfection and new surface disinfection without mechanical action are working independently and efficient. We will continue to support this important voluntary work.

Latest Statement of GLP Compliance
Our updated Statement of GLP Compliance is now available for download. It covers category 9 (according ChemVwV-GLP No. 5.3/OECD guidance): “Microbiological and biochemical testing of cleaning, disinfection, and sterilization procedures” as well as “In-vitro toxicological testing.” If you are interested in testing according to GLP category 9, please get in touch! The Statement of GLP Compliance ensures compliance with the OECD principles of good laboratory practice (GLP) as defined in the OECD guideline “OECD Principles of Good Laboratory Practice, ENV/MC/CHEM(98)17.” This includes, in particular, the proper planning, conduct, monitoring, documentation, and archiving of non-clinical safety studies so that the results are regulatory recognized and legally valid. GLP certification thus guarantees that our studies meet the requirements of national and international regulatory authorities and provides the necessary legal and evidentiary validity for regulatory submissions. Our institutes' certifications can be found here: LINK
