Sterility Test mgp-consulting.ch. Testing for sterility at all critical steps of production is strongly recommended. Sterility testing should start upon arrival of the tissue sample at the stem cell procurement site, depending on the tissue material used. Further in process controls for sterility should be imple mented at every critical step of the production proce ss., guidelines, e.g., serial low to high with a minimum of two days at each temperature or three to five days with a single temperature method, validated of course.

After transferring the contents of the container or containers to be tested to the culture medium add an inoculum of a small number of viable microorganisms (not more than 100 CFU) to the medium., The sterility test is generally recognized as a flawed test for its stated purpose. Since the original de-scription in 1932, this test has generated controversy as to its role in product quality testing and in terms of means to improve the assay. As early as 1956 Bryce published an article describing the two critical limitations of this test (1)..

The limit of detection of the complete method is therefore as low as possible and an acceptance criterion is defined based on this value (e.g. ≤ 1 log 10 CFU/mL). In commercial sterility, there is no enrichment broth, but the food item is incubated between seven and thirteen days prior to testing. increased assurance of sterility for aseptically produced products.

For the purposes of this part, the following definitions apply: (a) Aseptic processing and packaging means the filling of a commercially sterilized cooled product into presterilized containers, followed by aseptic hermetical sealing, with a presterilized closure, in an atmosphere free of microorganisms. The sterility test only examines for those bacteria and fungi which can grow under the particular cultural conditions of the test. Even with this more limited ‘pharmaceutical definition’ of sterility, the term sterility cannot be proved, and it can only be quoted in terms of probability.
