ABSTRACT:
The invention relates to a method for testing a sterilization packaging unit provided for sterilization of objects to be sterilized, in particular medical objects to be sterilized, for its efficacy against microbial recontamination of the sterilized objects after they have been sterilized. In accordance with the invention the packaging unit is charged with nutrient medium, subjected to a sterilization process and then stored for a period of time under ambient conditions. The packaging unit is then kept under conditions in which microbes multiply for cultivation of microbes which are present in or on the nutrient medium. The packaging unit is then opened and microbes, which have multiplied in or on the nutrient medium, are observed. The method permits the efficacy of the packaging unit with respect to its recontamination protection to be tested easily and reliably.
