Source of potential contamination – Determine the potential source of contamination, which may include Staphylococcus (skin, insect, etc.); Pseudomonas (water, plants, etc.); yeast and mold (spores) (environmental) 6. Investigation Report – Review firm’s investigation report of microbiological out of specification (OOS) test results; source of contamination; where there corrective action(s) taken; if any repeat testing performed; batch disposition; does it include related lots and ancillary systems? Was the product rejected or released? If released ask why? Evaluate justification. 7. Product Test Failure - When a firm has a final product or in-process test result that indicates a failure (USP test failure, OOS, etc.) ask– Were the results due to laboratory error or a true process contamination? 8. Focus Areas - During the investigation, there are two areas for the review to focus: the manufacturing site and the laboratory that determined the OOS result. The investigations may run concurrently between manufacturing and the laboratory. For ease of review the questions listed in #9 (below) deal with laboratory data and those in Section E concern the manufacturing review. The laboratory section covers those questions that should be asked for a critical review of the microbiological data accumulated for sterility failures, non-sterile medical product failures, etc. Section E covers the manufacturing area and is divided into aseptic manufacturing (high risk) and terminally sterilized products (low risk). 9. Laboratory Facility and Analytical Review a. Review QC records for proper/validated sterilization of all equipment and media used during the sterility test method: manifold/ Steritest; rinse fluid, culture media, canister kits, etc. b. Review the EM data acquired during sterility testing (i.e., settling plates, RODAC), simulation system controls, etc. What are the microbial species and their determined normal habitat (i.e., water, plants, people, etc.?) c. Review training records and qualification of analysts performing the test; interview and/or observe analysts d. Review the qualification of the bio-clean room facilities or isolator chamber used during testing.
