Suppression of Listeria monocytogenes by the Native Micro-Flora in Teewurst Sausage.

ABSTRACT: Modern consumers are interested in the use of non-chemical methods to control pathogens when heat sterilization is not an option. Such is the case with teewurst sausage, a raw spreadable sausage and a popular German commodity. Although Listeria was not found in teewurst, the optimal microbial growing conditions of teewurst coupled with the ubiquity of L. monocytogenes in nature, makes the possibility of contamination of products very possible. This pilot study was conducted to examine teewurst's native micro-flora's ability to suppress the outgrowth of L. monocytogenes at 10 °C using standard plate counts and PCR-DGGE. Traditional plating methods showed L. monocytogenes growth significantly decreased when in competition with the teewurst's native micro-flora (
