Raw meat can be contaminated by many pathogenic microorganisms. Although the majority of them are unable to multiply during refrigerated storage, Listeria monocytogenes is well known for its ability to grow at low temperatures. In order to inhibit growth of pathogens and to extend the shelf-life, antimicrobial substances can be added in food. Over the past years, research in the area of microbiological safety and shelf-life of food has focused on natural antimicrobials as a result of concern of consumers regarding synthetic additives.
