Abstract Background: Foodborne illnesses are considered as one of the most important public health problems particularly in developing countries like Ethiopia. This study aimed to determine the microbiological quality and safety of ready-to-eat foods in Yirgalem town, southern Ethiopia from November 2016 to August 2017. Methods: The collection of ready-to-eat food samples and laboratory-based microbiological analysis was used as the study design. A total of 160 food samples comprising of 40 ‘Injera firfir’, 40‘Bayeaynet’, 40 Vegetables and 40 Spaghetti were collected and analyzed for microbial contamination following standard microbiological methods. Ten grams of each food sample was transferred into 90 ml of buffered peptone water and homogenized for 5 minutes using a vortex mixer. The homogenates were serial diluted up to 10-7 and a volume of 0.1ml aliquot was spread plated on pre-solidified media of Aerobic plate count agar, MacConkey agar, Mannitol salt agar, and Salmonella-Shigella agar and incubate at 35-37oc for 24 hrs. Also, Potato Dextrose Agar was used for the isolation of fungi. Data were entered into Microsoft Excel and analyzed using SPSS version 20.0. Results: All the collected food samples were subjected to total aerobic mesophilic bacteria, Coliform bacteria, Enterobacteriaceae, Staphylococcal, Yeasts, and Molds counts. Accordingly, the mean counts expressed as log10 CFU/g of food for each group of the organism were 7.90 ± 0.71, 4.31±1.30, 4.32 ± 1.30, 6.70 ± 0.34 and 4.5 ± 1.01, respectively. The highest bacterial load 162(28.9%) was detected in ‘Injera firfir’ whereas the lowest 108(19.2%) case was investigated in Spaghettis. Regarding the food safety issue, the frequency of S. aureus, E. coli and Salmonella spp in the food samples were 54.4%, 43.8%, and 0.6%, respectively. Conclusion: The high microbial load and existence of foodborne pathogens in ready-to-eat foods in Yirgalem town, Southern Ethiopia is calling for the creation of awareness among restaurant and food establishment owners and food handlers concerning the hygienic practice.
