Occurrence of drug-resistant enteric bacteria and associated factors among food handlers of the Mass Catering Center: A laboratory-based cross-sectional study.

This study aimed to determine antimicrobial- resistance (AMR) enteric bacterial load and associated factors among Food Handlers (FHs) ofMass Catering Center (MCC), Ethiopia. From January to June 2020, a laboratory-based cross-sectional study was conducted using the standard Swab microbiological analysis method and the Kirby-Bauer disc diffusion method on 160 randomly selected FHs and food serving areas and analyzed with RStudio- 1.2.5033 for contamination, resistance level, and source determination. The contamination of AMR Escherichia coli was33.3% (95% CI, 31.5%, 36.4%), Salmonella 30% (95% CI, 29.8%, 36.0%) and Shigella 20% (95% CI, 19.2%, 26.9%) among the hand of FHs serving in MCC. The contamination was more likely associated with low work experience [AOR, 1.42 (95% CI: 1.22-1.87)], a low educational level [AOR, 1.62 (95% CI: 1.52-189)], irrational drug use characteristics [AOR, 1.75(95% CI: 1.64-2.00)], lack of sufficient food safety knowledge [AOR, 1.52 (95% CI: 1.32-1, 67)] of the FHs and the sanitary condition of the food serving area [AOR:1.98 (95% CI, 1.45, 2.53)]. The contamination of the hand of FHs serving in the MCC with AMR enteric FBB at the University cafeteria could indicate the likelihood of the occurrence of foodborne outbreaks.
