The production and filling processes are built to reduce the probable for that introduction of microorganisms into your solution. As being a consequence They are going to be central to any investigation right into a sterility test failure. Crucial elements of this are the utilities supporting the production environment which include steam, drinking water and air, the HEPA filters providing air into the production atmosphere plus the sterilizers plus the sterilization of elements, tanks and filling strains.
Test outcomes reviewed must incorporate both of those bioburden outcomes and contamination indicators which include pyrogen/endotoxin testing. The situation of the Uncooked material containers and the dispensing process should also be reviewed.
If production facilities and controls are appreciably much better than These for sterility testing, the Risk exists of mistakenly attributing a beneficial sterility test final result to the defective laboratory even when the product tested could have, actually, been non-sterile.
Common possibility administration instruments such as Failure Manner Consequences Investigation, or Fault Tree Analysis, could possibly be helpful to determine, examine and Consider the hazards as well as their prospective to acquire brought about the contamination [2]. Mainly because of here the opportunity variability of microbiological success, the investigation shouldn't be restricted to information and facts/effects regarding the specific batch, but should consist of a broader evaluate of historical outcomes and tendencies. Uncommon events must be fully investigated to understand their opportunity impression.
Pharmaceutical organizations are demanded by regulatory authorities to carry out extensive investigations into microbial contamination events relevant to aseptic producing of sterile items.
