In 1998–99, a multistate outbreak of listeriosis in the United States was associated with
contaminated hot dogs and was caused by a strain of Listeria monocytogenes serotype 4b …

Listeria monocytogenes contamination of ready-to-eat foods has been implicated in
numerous outbreaks of food-borne listeriosis. However, the health hazards posed by L …

Human listeriosis is generally caused by consumption of ready-to-eat (RTE) foods that are
stored for extended periods of time at refrigeration temperatures and that permit the growth …

Listeria monocytogenes is the etiological agent of listeriosis, a severe food-borne illness.
The population of L. monocytogenes is divided into four lineages (I to IV), and serotype 4b in …

Strains of Listeria monocytogenes serotype 4b account for a large fraction of sporadic
listeriosis cases, as well as all major food-borne epidemics attributed to this pathogen. We …
