A less utilized application area is the use of lactic acid bacteria (LAB) as protective cultures to enhance safety and quality of raw processed meat products such as raw sausages (e.g. fresh chorizo, longaniza, fresh bratwurst, spreadable German sausage) and processed minced meat products (e.g. hamburgers). Spraying the culture onto the surface of cooked meat products to prevent secondary contamination during further handling is another application. By competitive exclusion the protective culture suppresses the

development of spoilage bacteria as for example indigenous LAB producing acetic acid or gas and Leuconostoc ssp., often resulting in off flavour. Additionally, Listeria monocytogenes is inhibited by bacteriocins which the protective culture produces.
