Abstract

First Report of Listeria monocytogenes Serotypes Detected from Milk and Milk Products in Sri Lanka

Highlights

Listeria monocytogenes is a pathogenic bacterium that can cause Listeriosis in humans and various animal species
Contamination of milk and milk products with L. monocytogenes is a serious problem to the world (Kozak et al, 1996; Donnelly, 2004; Rudolf and Siegfried 2001; Conly and Johnston, 2008; Pan et al 2006; Molla et al, 2004)
A total of 154 samples of raw and pasteurized milk samples were collected from farms and milk collecting centers and 112 samples of milk products such as cheese, curd, yogurt and ice cream were obtained from retail outlets including supermarkets, farm shops, groceries, milk booths and public markets (Table I)

Summary

INTRODUCTION

Listeria monocytogenes is a pathogenic bacterium that can cause Listeriosis in humans and various animal species. Two large outbreaks in human population were reported from California, (Linnan et al, 1988), and Switzerland, (Bille, 1990). Another listeriosis outbreak occurred in Switzerland during 2005 (Bille et al., 2006). Two studies have been reported in Sri Lanka to ascertain the presence of L. monocytogenes in our dairy products. Listeria Monocytogenes Serotypes Detected from Milk and Milk Products in Sri Lanka. The main aim of our study is to detect the circulating serotypes in dairy industries using molecular methods and primarily to trace the lineage of these serotypes, as these serotypes are responsible for outbreaks and epidemics
