Bacterial contamination in ready-to-eat (RTE) foods prepared and sold by small businesses in middle Thailand was surveyed. The 135 samples were randomly purchased from open markets and supermarkets in Bangkok and Pathum Thani provinces during May 2013 to February 2015. The results indicated that the rate of contamination in cooked pork, chicken meat and cooked aquatic items were 13/39 (33%), 18/45 (40%) and 14/57 (25%), respectively and the rate of bacterial contamination of collected samples from open market and supermarket were 26/67 (39%) and 19/68 (27%), respectively. Therefore, no statistically significant difference of contamination rate between two kinds of market or among three categories of food. The most contaminated pathogenic bacteria was Staphylococcus aureus 27/135 (20%) while that of Salmonella spp. was the lowest 5/135 (4%) in each categories of collected food samples. Implementation of suitable hygienic practices in the small food businesses are thought to be required to reduce the risk of foodborne illnesses caused by the consumption of RTE foods sold in middle Thailand.
