5.1 During the sterility test of the product, if evidence of microbial growth is found in inoculated SCDM and FTGM tubes, then preserve the positive tube along with negative control till the complete investigation.
5.2 Immediately streak a loopful growth from the positive tube to the preincubated SCDA plate in duplicate.
5.3 If the growth of suspension is taken from FTGM tube then incubated at 300℃ to 350℃ for 48 hrs and if it is taken from the SCDM tube then incubated at 200℃ to 250℃ for 72 hrs.
5.4 After incubation, observe the colony and find the unknown microorganisms per SOP No. for Identification of unknown microorganisms.
5.5 Check the sterilization details such as temperature, pressure, holding time, and status of indicator strip during sterilization of media, filtration assembly, and other materials used while performing the sterility test.
5.6 Check the cleaning details of the sterility testing area.
5.7 Check the results of environmental monitoring taken while performing the sterility.
5.8 Identify the colony as per SOP No. “the Identification of unknown microorganisms” in the plates exposed.
5.9 If the colony observed in LAF is the same as found in the positive tube, there are chances of contamination during testing. The test may be considered invalid.
5.10 After reviewing QC and production details, compiles all the data and find the root cause.
