Which test might be used weekly to validate the sterilization process?

The use of Bacillus stearothermophilus spore tests is well-established in the healthcare industry as a validation method for steam sterilization processes. This particular type of spore test is highly effective because it utilizes spores from Bacillus stearothermophilus, which are more resistant to moist heat than most microorganisms. As a result, if these spores are killed during the sterilization process, it indicates that the temperatures and conditions required for effective sterilization were sufficiently achieved.

Regular weekly testing with these spores helps to ensure that sterilization equipment is functioning properly. If the spores survive, it signals that there may be a problem with the sterilization process, prompting further investigation to ensure patient safety. Overall, the robustness of Bacillus stearothermophilus spores in testing conditions makes them the preferred choice for routine validation of sterilization efficacy in healthcare settings.
