Cleaning validation is not new, but the official requirements were updated in the revised Annex 15 in order to reflect the current state of the art. Three aspects are in the foreground:
Michael Hiob, GMP inspector, gives a high-quality overview on agency expectations on cleaning validation. Every cleaning validation should be based on a defined cleaning process that is described in a cleaning instruction. The parameters that have to undergo mandatory validation are to be determined by a risk analysis. Limits have to be defined for product residues, cleaning agents and microorganisms. Sampling processes and analytical methods must be tested for suitability and/or validated in advance. The cleaning validation can be carried out on a selected worst-case example that is representative of a machine or product group. The documentation includes a validation plan and report. It should be ensured that the validation status is maintained on an ongoing basis. Changes must be evaluated to see if a revalidation is necessary. (Michael Hiob, PhD)
