What is the minimum temperature required for OPA to achieve high-level disinfection?

The minimum temperature required for Ortho-Phthalaldehyde (OPA) to achieve high-level disinfection is indeed 68°F. Operating at this temperature enables OPA to effectively kill a wide range of microorganisms, including bacteria, viruses, and fungi, which is crucial in ensuring that flexible endoscopes are properly disinfected between uses.

High-level disinfection is essential in healthcare settings to prevent infection transmission and protect patient safety, especially for devices that come into contact with mucous membranes. OPA has become a popular high-level disinfectant due to its effectiveness, low odor, and compatibility with heat-sensitive medical instruments.

Temperatures below the required minimum may not provide adequate disinfection, allowing for potential survival of pathogens. Therefore, following the correct temperature guidelines for using OPA will ensure the highest standards of infection control are maintained.
