Abstract
Food-borne illness is a public health concern in developing countries because of improper food handling and sanitation practices, irregular medical checkups, lack of clean water supplies, and inadequate education among food handlers. This study investigated the burden of bacterial food-borne illness, antibiotic resistance patterns, and associated factors among food handlers in prison and nonprison food establishment settings. A cross-sectional study was conducted from August 2022 to January 2023 among asymptomatic food handlers in Shewa Robit town. A total of 384 food handlers participated. Data were collected using structured questionnaires. Stool and hand swab samples were collected and cultivated onto MacConkey agar, xylose-lysine-deoxycholate, Mannitol salt agar, and blood agar, and incubated at 37°C. Bacterial species were identified using biochemical tests and gram staining. Mueller-Hinton agar was used in Kirby Bauer's disk diffusion method. Data were entered and analyzed using SPSS. Descriptive and logistic regression analysis were performed. Fecal and hand carriage rate of bacterial isolates were 106 (27.6%), and 214 (55.7%), respectively. Out of the 102 bacterial isolates, the most common ones from stool samples were Escherichia coli 71 (18.5%), Klebsiella aerogenes 12 (3.1%), and Salmonella spp. 7 (1.8%). Among 214 bacterial isolates, coagulase-negative Staphylococci 115 (29.9%) and Staphylococci aureus 66 (17.3%) were identified from hand swab samples. Hand washing practice after restroom with water (adjusted odds ratio [AOR] = 2; 95% confidence interval [CI]: 1.16-3.45), irregular medical checkups (AOR = 2.49; 95% CI: 1.35-4.59), and did not receive food safety and hygiene training (AOR = 2.33; 95% CI: 1.34-4.05) were statistically significant association with food-borne illness. Foodborne pathogens pose a serious health risk in the study areas. The level of antimicrobial resistance are also concerning. Food handlers should therefore get strict regular health education, medical checkups, and training programs to prevent the spread of infections to the customers.
