Abstract
Bacteria are the major pathogens affecting food safety and foods of animal origin are main vehicles of human illness since food animals are the main reservoirs for many food-borne pathogens. Moreover, emergence and spread of multidrug-resistant food-borne bacterial pathogens become a significant public health concern globally. A cross-sectional study was conducted from October 2019 to July 2021 to estimate the prevalence, identify associated factors, and determine antibiotic resistance pattern of Salmonella species from foods of bovine origin in Dessie and Kombolcha towns. A total of 384 samples were collected. Simple and systematic random sampling techniques were employed for sampling milking cows and carcasses among cattle slaughtered at abattoirs, respectively. Samples from milk tanks, milk products, and beef were also selected randomly. Salmonella species were isolated and identified according to recommended standard bacteriological protocols. All the detected Salmonella species isolates were screened for in vitro antimicrobial susceptibility using agar disc diffusion method against 12 antimicrobial disks. The collected raw data were analyzed using descriptive and inferential analysis techniques. The overall prevalence rate of Salmonella species was 7.0%. The highest prevalence rate of Salmonella species (16.7%) was obtained from milk tank samples but not detected in milk products. Multidrug resistance to three and more than three drugs was observed among all isolated Salmonella species. All Salmonella species isolates (100.0%) were found to be resistant to Erythromycin, Tetracycline, and Vancomycin. The majority of the isolates (96.3%) were also resistant to Doxycycline and Polymyxin B. On the other hand, all isolates (100.0%) were sensitive to Gentamicin and Ciprofloxacin. The detection of multidrug-resistant Salmonella species showed that foods of bovine origin produced in the study sites were not safe for consumption. Hence, preventive measures are required to reduce bacterial contamination, concurrently to improve the wholesomeness and safety of foods of bovine origin.
