Antimicrobial Testing Methods & Procedures (ATMP)


The Standard Operating Procedures (SOPs) for atimicrobial testing methods describe the methods used by the OPP Microbiology Laboratory to determine the efficacy of hard surface disinfectants against Staphylococcus aureus, Pseudomonas aeruginosa, Salmonella choleraesuis, and Mycobacterium bovis BCG. Methods are available for liquid, spray, and towelette formulations. The SOPs were derived from official AOAC (AOAC International) methods. The specific AOAC method is cited in each SOP. The SOP for testing towelette products is a modification of AOAC's Germicidal Spray Products Test (961.02).

In addition to the test method SOPs, which may be downloaded from the ATMP Index, several SOPs which support the testing activities are listed (e.g., SOPs for carrier screening, carrier counts, test microbe maintenance). Copies of those SOP's may be requested from the contacts listed below.
