MAI ET AL.: JOURNAL OF AOAC INTERNATIONAL VOL. 101, NO. X, 2018 1 FOOD BIOLOGICAL CONTAMINANTS Performance Validation of the Microbiologique MicrofilmTM Test System for AOAC Research Institute Performance Tested Method SMCertification AOAC Performance Tested Method SM 051702 Abstract ANNA SHAPOVALOVA and HARISH K. JANAGAMA Molecular Epidemiology, Inc., 15300 Bothell Way NE, The Microfilm™ Test System is intended for quantitative Lake Forest Park, WA 98155 microbiology and consists of three types of Microfilms for aerobic LONG VUONG and ALEX FRIEDRICH plate count (Microfilm APC), total coliform and Escherichia coli IEH Laboratories and Consulting Group, Inc., 15300 Bothell count (Microfilm TCEc), and yeast and mold count (Microfilm Way NE, Lake Forest Park, WA 98155 YMC). This study evaluated the performance of the Microfilm DYLAN JOHNSON Test System against International Organization for Standardization Molecular Epidemiology, Inc., 15300 Bothell Way NE, (ISO) methods on 20 food matrixes and 2 environmental surfaces. Lake Forest Park, WA 98155 Ruggedness, robustness, and stability were also determined, LOURDES M. NADALA while inclusivity and exclusivity studies were performed on Molecular Epidemiology, Inc., 15300 Bothell Way N.E., Microfilm TCEc and YMC. An independent laboratory evaluated Lake Forest Park, WA 98155; Microbiologique, the performance on four food matrixes and one environmental Inc., 8215 Lake City Way NE, Seattle, WA 98115 surface. No significant differences and high correlation coefficients VAN NGUYEN were observed between the Microfilm Test System and the Microbiologique, Inc., 8215 Lake City Way NE, Seattle, corresponding ISO methods (ISO 4833-1:2013 for APC, ISO WA 98115 4832:2006 for total coliform count, ISO 16649-2: 2001 for E.
