ABSTRACT:
A testing unit and a method of testing a sterilization packaging unit for microbial contamination of sterilized objects after they have been sterilized are disclosed. The testing unit includes a dry matrix for accommodating a nutrient medium and a receptacle containing a liquid. By applying the liquid onto the matrix, the matrix is provided with a nutrient medium. In the method, the testing unit is inserted into the sterilization packaging unit which is sterilized and stored. At a desired point in time, the receptacle is opened in order to produce the nutrient medium in the matrix. After a possible multiplication of microbes on the matrix, an observation of microbes takes place. The invention also relates to a sterilization packaging unit which has a rigid outer casing and is suitable for the application of the method.
