For added convenience, it is recommended that QuickBag Enrichment Media are dispensed using the Thermo Scientific Automated Diluter (DB4150A).

Half Fraser Broth is a modification of the USDA-FSIS UVM secondary enrichment broth and is based on the formula described by Fraser and Sperber1. Blackening of the medium is presumptive evidence of the presence of Listeria spp. All Half Fraser Broth enrichment cultures should be subcultured to plating medium.
