| Abstract: | Increased confidence in conductimetric detection of salmonellas was achieved by combining a bacteriophage-based test with use of a selenite cystine trimethylamine oxide dulcitol medium and a modified lysine decarboxylase broth. All 81 Salmonella isolates tested were detected and few of the 39 non-salmonellas gave false positives. Results from the screening of 43 inoculated product samples further support the use of this simple, rapid method for routine salmonella testing in the food industry. |
