| Abstract | The aims of this research were to evaluate consumer behavior regarding the consumption of ready-to-eat foods and to evaluate the prevalence of pathogens in ready-to-eat food products obtained from the markets of Khon Kaen, Thailand. The research was divided into two parts; part one was a consumer behavior survey. The results showed top three highly consumed ready-to-eat foods were fresh vegetable salads, followed by sandwiches and Thai fresh spring rolls, respectively. Subsequently, the microbial contamination in the selected food products was collected and analyzed in Part two. The 54 samples were collected from two types of markets; open markets and supermarkets located in Khon Kaen. The presence of contaminated pathogenic bacteria; Salmonella spp., Listeria monocytogenes, Staphylococcus aureus was investigated by selective media. Poor hygiene was indicated by total coliforms and the presence of Escherichia coli. The results revealed that Salmonella spp. was detected in 5 of 27 (19%) samples of open markets and 5 of 27 (19%) samples of supermarkets. L. monocytogenes was detected in 4 of 27 (15%) samples of open markets and 3 of 27 (11%) samples of supermarkets. S. aureus was detected in 8 of 27 (30%) samples of open markets and 9 of 27 (33%) samples of supermarkets. Total coliforms were contaminated in 27 of 27 (100%) samples of open markets and 23 of 27 (85%) samples of supermarkets. E. coli was contaminated in 2 of 27 (7%) samples of open markets and 1 of 27 (4%) samples of supermarkets. A contamination of L. monocytogenes in open markets was higher than that in supermarkets. A contamination of S. aureus in supermarkets was higher than that in open markets; however, a contamination of Salmonella spp. in supermarkets was equal to that in open markets. This data provided food safety information of ready-to-eat foods for consumption of both markets in Khon Kaen. |
