A multiple-locus variable-number tandem repeat analysis (MLVA) of Listeria monocytogenesisolated from Norwegian salmon-processing factories and from listeriosis patients
SUMMARY The objective of this study was to characterize Listeria monocytogenes isolated from farmed Atlantic salmon ( Salmo salar ) and the processing environment in three different Norwegian factories, and compare these to clinical isolates by multiple-locus variable-number tandem repeat analysis (...

L. monocytogenes with this profile has previously been associated with at least two known listeriosis outbreaks in Norway, neither determined to be due to fish consumption. However, since this profile was also found in fish and in the processing environment, fish should be considered as a possible food vehicle during sporadic cases and outbreaks of listeriosis.
