I. INTRODUCTION
Nham is a traditional Thai fermented meat which has been popular among consumers in Thailand. It is normally eaten without cooking and consider being ready-to-eat after 3-4 days of fermentation process [1, 2]. It has been reported that Nham sold in retail markets contaminated Salmonella Anatum, Listeria monocytogenes and Staphylococcus [3, 4]. However, pathogen contamination can be reduced by using starter culture to achieve an acidic pH of ≤ 4.6 during fermentation [5]. Therefore, recent studies were aimed on inhibition of pathogen during product fermentation [6, 7].
