If a new cleanroom is built to meet the specs of the old cleanroom and the product has not changed, the process has not changed and the operators have not changed - do you need to re-validate the sterilisation process?

Re: Eto sterilisation re-validation

You can probably justify with a paper review by restating all of those factors in detail if you can provide proof that your bioburden is in the same range.

...if you can provide proof that your bioburden is in the same range.
Pay attention to both numbers and types of organisms.

If a new cleanroom is built... the process has not changed...
I'm 99% sure that if the operations have moved to a new cleanroom facility, the process must have changed in some ways, not necessarily negligible, regardless of specs, SOPs, personnel etc. ;) If you look close enough you will spot the differences...

Yes, the relocation involves dismantling and reinstalling ... that calls for a requalification and revalidation.

There was an earlier FDA warning Letter issued to Lydall Inc. for ETO relocation -

2. Failure to review and evaluate a process and perform revalidations where appropriate when changes or process deviations occur, as required by 21 CFR 820.75 (c). (FDA 483 item #2) Specifically,

a When your manufacturing process was relocated to North Carolina, the Et0 sterilization process was not revalidated. (FDA 483 item # 1.c).
