Evaluation of the MicroWorks, Inc. Swab Sampling System (MSSSTM) for Use in Performing Quantitative Swab Sampling.

The purpose of this study was to qualify the MicroWorks, Inc. Swab Sampling System (MSSS™) swab kit for use in sampling cleanroom surfaces for bioburden. A six-part study was performed to demonstrate the suitability of the swab materials, the recovery of bioburden from typical cleanroom surfaces, the neutralization of typical disinfectants used in cleanrooms, the removal of diluents from the swabbed surface, and the hold time for test samples.

Detection of Salmonellae and Other Enterobacteriaceae by Commercial Deoxyribonucleic Acid Hybridization and Enzyme Immunoassay Kits.

Cultures of 294 Salmonella and 100 other Enterobacteriaceae isolates were comparatively analyzed by the GENE-TRAK Salmonella Assay, the Report Salmonella Visual Immunoassay, and the Organon Teknika Salmonella-Tek assay. Of the Salmonella isolates, 99.0% were reactive in the GENE-TRAK assay, 98.

Efficacy of Petrifilm™ E. coli Count Plates for E. coli and Coliform Enumeration.

The Petrifilm E. coli Count plate (PEC) method was compared to the AOAC MPN method to determine the efficacy of the PEC method to detect E. coli and coliforms in 115 inoculated cheese samples, 94 vegetables samples, and in 100 naturally contaminated poultry samples.
