AOAC Method Number 2014.05
Method Name Rapid Yeast And Mold
Rationale (based on selection
criteria)
Rapid Yeast and Mold Petrifilm (RYM) by 3M was approved for First Action in
December 2014 (OMA 2014.05). RYM is a practical solution to a challenging problem
for many laboratories. It offers a shorter time to result which is closer to other analyses
that may be performed (i.e. APC, Salmonella) allowing for companies to release
product to the marketplace sooner. The test offers yeast and mold results as early as
48 hours.
Another noteworthy aspect of the method is the improvement in reading colonies
compared to their traditional method. 3M made this improvement by reducing
spreading of molds that provides clearer colony formation and easier, more accurate
counting of CFUs.
Upon review of 3M's collaborative study, the recommendation of the Microbiology ERP
to move the method to first action was unanimous.
