Investigation of Microbial Quality in Ready-to-Eat Food from Cafeterias of Thammasat University at Rangsit Centre
Main Article Content
Abstract
This study investigates the microbial quality in the ready-to-eat food using the microbiological food quality criterion, which determines coliform content, fecal coliform, and Escherichia coli using the most probable number (MPN) method. By collecting ready-to-eat food samples from cafeterias of Thammasat University at Rangsit Centre, the samplings were 4 categories of foodstuff, i.e., food that goes through a lot of heat, food over medium heat, food that does not pass heat, and beverages. A total of 120 samples, 30 of each category, were collected from October to December 2016. The analysis showed that 114 (95 %) samples ready-to-eat food did not meet the criteria. Food over medium heat and beverages showed the highest number of 30 (100 %) samples, followed by food that has not been heat-treated 28 (93.33 %), and food that goes through a lot of heat 26 (86.67 %) samples. This research suggests that ready-to-eat foods that are sold can carry pathogens. Therefore, measures should be taken regarding food sanitation and personal hygiene of workers to avoid contamination.
