Recovery/Reprocess for aseptic

Dear Validation Collegue,

I have a sterile liquid product. It was sterilized using filtration system and filled into vials and ampoule.


  1. Can I reprocess the rejected (particulate reason) filled product?
  2. Can I top up with 2nd recovery batch and give new batch no. with shortest expiry date?

I honestly think it was a big NO. Perhaps this forum have another Idea coz’ I’ve found this practice was already going on in certain sterile company.

Thanks in advance.
