The article highlights the focus placed on the detail and specific wording in the draft revision of [EU GMP Annex 1](https://www.cherwell-labs.co.uk/eu-gmp-and-annex-1-the-new-version), in particular, regarding to environmental monitoring. It is anticipated that the revised Annex 1 document will be released in January 2022. Here are extracts from the article: “The much-discussed revision of the EU GMP Annex 1 is hopefully nearing conclusion with the release of the document anticipated in early January 2022. A lot of focus has been placed on the detail and specific wording within this key document and environmental monitoring is a key part… The all-important Annex 1, as part of EU GMP, applies to the manufacture of sterile products and its purpose is to ‘prevent microbial, particulate and pyrogen contamination in final product’… [![New! Revised Environmental Monitoring Process and Validation Guide](https://no-cache.hubspot.com/cta/default/2885977/986950a2-0111-48dc-a8cb-1d444e27031d.png)](https://cta-redirect.hubspot.com/cta/redirect/2885977/986950a2-0111-48dc-a8cb-1d444e27031d) The latest EU GMP Annex 1 draft revision calls for continuous EM in sectors with stringent environmental control and which carry a risk to public health should the manufacturing be contaminated. Continuous EM is the most effective way of reducing contamination risk, which is why these latest regulations now place such a strong emphasis on its more widespread use.” The article covers: - Continuous EM in Annex 1 - Moving to continuous - A holistic programme - The importance of continuous - Aiming for zero - Stepping towards a global standard The article advises that “Another key factor in the importance of the new EU GMP Annex 1 revision is the fact that it will also be used by the Pharmaceutical Inspection Co-operation Scheme (PIC/S). the WHO, as well as EU GMP. This revision really represents an important step towards a truly global standard in cleanroom environments.” The article can be found on pages 21, 22 and 24 of the November 2021 issue of Cleanroom Technology.
