AOAC Use Dilution Test for Liquid Products

Test Purpose
The purpose of this microbiology lab test is to determine the efficacy of a client's product using the AOAC Use Dilution Method to comply with the U.S. Environmental Protection Agency and other regulatory agency requirements.

Test Summary
A film of bacterial cells is dried on a surface of stainless steel carriers and is then exposed to the test substance for a specified contact time. After exposure, the carriers are transferred to vessels containing neutralizing subculture media and assayed qualitatively for survivors. Appropriate viability, carrier population, and neutralization controls are performed.
