AOAC 991.47 - Evaluation of disinfectant sample for its bactericidal activity against Salmonella choleraesuis
Application
Mandatory test strains
- Salmonella choleraesuis
- The carriers are inoculated with the test organism and subsequently exposed to the test product for specified contact times.
- After treatment, carriers are transferred to a recovery medium containing neutralizing compounds.
- The recovery medium is incubated to qualitatively assess any remaining microbial growth.
Benefits
- Ensures accurate evaluation of a disinfectant's bactericidal efficacy against Salmonella choleraesuis.
- Validates bactericidal claims on product labels, enhancing consumer trust and regulatory compliance.

Abstract
AOAC 991.47 test lays down a standard guideline to test the efficacy of a given disinfectant sample against Salmonella choleraesuis on a hard surface carrier.
AOAC 991.47 is an important guideline that helps to verify the performance of the disinfectant sample against Salmonella choleraesuis, a highly pathogenic species of Salmonella that causes septicemic diseases. AOAC 991.47 thus serves as the standard testing guideline for registration of the disinfectants that claim to have bactericidal efficacy against Salmonella choleraesuis as per regulatory requirements set by the US Environmental Protection Agency (EPA) and US Food and Drug Administration (FDA).
AOAC 991.47 Test Method
- 70 carriers are used for a single test sample. Each carrier is inoculated with the test organism.
- In the next step, 60 carriers contaminated with test microorganisms are exposed to the test product for specific contact times and the remaining 10 are kept as untreated controls.
- At the end of contact time, treated carriers are immediately transferred to a recovery medium enriched with neutralizing compounds.
- Recovery medium is then incubated for a comprehensive qualitative assessment of any potential growth that may still be present after disinfectant treatment.
