Here’s an extract from the article: *Environmental monitoring (EM) is an established method of reducing the risk of contamination of sterile products, and is used by manufacturers in the pharma and associated healthcare industries in the manufacture of advanced medicinal products, as well as in the specialist food industry. * *The importance of EM to maintaining the sterility of medicinal products is reflected in the latest EU GMP Annex 1 draft revision, which calls for continuous EM in sectors with stringent environmental control and which carry a risk to public health upon contamination at manufacturing facilities.* *Why do the latest regulations place such a strong emphasis on continuous EM? The short answer is that it is the most effective way to reduce contamination risk.* The article covers: - The Benefits of Continuous EM - Reducing Long-Term Contamination Risk - Transitioning to Continuous EM - Important Considerations for a Continuous EM Programme - Continuous Air Monitoring Is Crucial for Annex 1 Compliance - Target Zero CFU - Annex 1 Compliance Puts Manufacturers in a Stronger Position [![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 article advises that "with the new Annex 1, manufacturers of sterile medicinal products should start evaluating the needs of their business, and planning how to transition to continuous EM as soon as possible".  With regulations on EM only expected to get tighter, moving to continuous EM and learning how to accurately monitor, report, and counter identified risks is crucial. Not only for compliance with the latest Annex 1 revision, but this can also enable businesses to adapt more rapidly to any future regulatory changes.
