Product Summary and Explanation
Listeria monocytogenes, described in 1926 by Murray, Webb and Swann, is a widespread problem in public health and food industries. This organism has the ability to cause human illness and death, particularly inimmunocompromised individuals and susceptible pregnant women. Epidemiological evidence fromoutbreaks of listeriosis indicate the principle route of transmission is via the consumption of foodstuffs contaminated with Listeria monocytogenes. Implicated vehicles of transmission include turkey frankfurters,coleslaw, pasteurized milk, Mexican style cheese and pate. Listeria species are ubiquitous in nature,present in a wide range of unprocessed foods and in soil, sewage, and river waste.
Fraser Broth Base is based on the formulation of Fraser and Sperber. This medium is used in rapiddetection of Listeria from food and environmental samples. Listeria species grow over a pH range of 5.0 -9.6, and can survive in food products with pH levels outside these parameters. Identification of Listeria isbased on successful isolation of the organism, biochemical characterization, and serological confirmation.
