| Introduction: Infectious diseases among ho-spitals are a major healthcare problem in the world. Some of these infections are cau-sed by ingestion of contaminated foods in the hospitals. The aim of this study was to investigate the role of hospital foods in the transmission of clinically important bacteria into the hospital environment.
Materials & Methods: Frequency of the main bacterial pathogens responsible for h-ospital infections were studied among sam-ples from foods, food handlers and food p-rocessing devices. Swab culture and aerobic plate count assay were used for the isolation of suspected bacteria. Colony count of each culture and biochemical or molecular ident-ification of each isolate was determined according to standard methods. Antim-icrobial susceptibility of each bacterial iso-late was determined according to the latest clinical laboratory standard guideline.
Findings: Among the 200 samples under study, the highest frequency of contam-ination (40%) was seen among utensils. Furthermore, Staphylococcus aureus show-ed the highest frequency (16%) among the obtained isolates, while Escherichia coli re-presented 8% of the contaminations. Fewer rates of contaminations were belonging to other responsible bacterial pathogens, inclu-ding Pseudomonas spp., Acinetbacter spp. and Enterococcus spp. (0-4.6%). Among the Staphylococcus aureus isolates, the mu-ltidrug resistance phenotypes were observed to be 18.7%. This phenotype was observed among 52.9% of Escherichia coli isolates but not among other isolates. Among the studied samples, the highest frequency of multidrug resistance was seen among uten-sils.
Discussion & Conclusion: Outbreaks of food borne disease has been reported in ho-spitals. High frequency of clinically imp-ortant bacteria among utensils compared with samples of foods or food staffs, and the presence of enteric or skin marker bac-teria in these samples revealed the possible role of hospital foods as a risk factor for dissemination of pathogenic bacteria into hospital environment. |
