Use Fraser Broth Base for making Fraser and Fraser 1/2 Broths. With the addition of the supplement, use Fraser 1/2 Broth as a selective enrichment medium for the growth of Listeria, including Listeria monocytogenes, in products intended for human and animal consumption. The supplemented broth can be used as a primary enrichment step for the identification and enumeration using RAPID'L.mono or RAPID'Listeria spp. Agar Plates. Fraser 1/2 Broth without the supplement can be used for recovery of bacteria after sublethal injury caused by heat, preservatives, or other processing techniques.
