Listeria monocytogenes is a foodborne pathogen which causes listeriosis, an illness characterized by meningitis, encephalitis and septicemia, especially in immunocompromised individuals, elderly and pregnant women. It has been reported that several outbreaks of listeriosis were due to consumption of contaminated food products, such as dairy, meat, vegetable and seafood. L.monocytogenes is notable for its ability to grow at refrigeration temperatures, unlike most enteric pathogens. This has considerable significance for food safety as it means chilling to 4ºC could not be relied upon to preventthe growth of the organism to a dangerous level. The aim of this study is to determine the incidence of L. monocytogenes in selected food products of animal origin obtained from processing plants in Central Region of Malaysia. A total of 130 samples were collected during January to August 2018 from 19 processing plants in four states of Malaysia (Selangor, Negeri Sembilan, Melaka and Wilayah Persekutuan Kuala Lumpur). The food samples comprising of 30 dairy products (ice-cream, butter and cheese) and 100 meat products (smoked frankfurter, sausages, sausages and sandwich) were analyzed for the presence of L. monocytogenes using selective enrichment and isolation protocol. L. monocytogenes was not detected in any of the samples. More comparative studies are needed to detect the existence of this pathogen from a variety of food and the environment to ensurethe importance of implementing appropriate prevention and control measures that will help to prevent L. monocytogenes food contamination in the manufacturing environment.
