Abstract：
:Six different enrichment media and five selective plating media were compared for their suitability for the recovery of Listeria monocytogenes from dairy products. These included media used to test milk products by the U.S. Food and Drug Administration (FDA) and the U.S. Centers for Disease Control (CDC), and media developed by the U.S. Department of Agriculture (USDA) for testing meat and poultry products. Test samples included naturally contaminated goat's milk, cultured milk products and ice cream manufactured with L. monocytogenes, and unpasteurized milk inoculated with heat- and freeze-injured cells of L. monocytogenes. Generally, the media and two-stage enrichment protocol developed by the USDA, with plating of samples after two consecutive 24-h incubation periods, yielded better recoveries than all other enrichment media incubated for 24 h. A modified USDA procedure, incorporating nonselective pre-enrichment of samples by omitting acriflavine and nalidixic acid from the primary USDA enrichment broth, and transfer of a larger volume of the initial culture broth to the secondary enrichment media, significantly increased recoveries of low numbers of sublethally stressed L. monocytogenes. Prolonged incubation of samples in the FDA enrichment broth, for 7 days, did not consistently improve recoveries over the initial 24-h incubation time of the medium. The selective plating medium developed by the USDA, lithium chloride-phenylethanol-moxalactam agar, was the most effective plating agar for isolation of L. monocytogenes following enrichment of samples in any broth culture, and increased recoveries of L. monocytogenes by 19-40% compared with other selective agar media tested.
