Abstract

We evaluated the robustness of sterilization technologies when spores and bacteria were placed on “dirty” instruments and overlaid with blood. The results illustrate that steam sterilization is the most effective sterilization technology with the largest margin of safety, followed by ethylene oxide and hydrogen peroxide gas plasma.
