What is the update guidance on cleaning and disinfecting in Annex 1?

EU GMP Annex 1 states that for disinfection to be effective, prior cleaning to remove surface contamination should be performed. Cleaning programmes should also be designed to effectively remove disinfectant residues.

More than one type of disinfecting agent with different modes of action should be used for maximum effectiveness against bacteria and fungi. The periodic use of a sporicidal agent is also endorsed. A back up disinfectant may be required in case of a build-up in resistance to other agents.
