What is the biological indicator of choice for Peracetic acid sterilization?

The biological indicator of choice for Peracetic acid sterilization is not represented accurately in the selected answer. When considering the appropriate biological indicators for this method of sterilization, Bacillus atropheus and Geobacillus stearothermophilus are both commonly used for monitoring different types of sterilization processes.

Peracetic acid is a high-level disinfectant and sterilant effective against a wide range of microorganisms. To ensure that the sterilization process has effectively killed all potential spores, using biological indicators that correspond to the conditions of that sterilizer is critical. Generally, Bacillus atropheus is recommended specifically for vaporized hydrogen peroxide systems, while Geobacillus stearothermophilus is often preferred for moist and dry heat sterilization.

For Peracetic acid sterilization, Geobacillus stearothermophilus is an appropriate biological indicator as it can withstand the specific conditions created during this type of sterilization process. Therefore, the biological indicator for monitoring Peracetic acid sterilization would not be “none”, but would instead be one of the mentioned bacteria. Thus, understanding the appropriate biological indicator in the context of Peracetic acid sterilization is essential for adequate monitoring of sterilization efficacy.
