Disinfactant Efficacy test

Question

Accepted Answer

Disinfectant efficacy test is performed to determine the effectiveness of a disinfectant against microorganisms.

The test is performed by inoculating a known concentration of microorganisms onto a surface and then treating it with the disinfectant.
After a specified contact time, the surface is sampled and the number of surviving microorganisms is determined.
The test is usually performed using a variety of microorganisms, including bacteria, fungi, and viruses.
The disinfectant must meet certain criteria to be considered effective, such as reducing the number of microorganisms by a certain percentage.
Examples of disinfectant efficacy tests include the AOAC Use-Dilution Test and the ASTM E1054 Standard Test Method for Evaluation of Inactivators of Antimicrobial Agents.
