Background & Objectives: There is an increasing tendency among people for the consumption of ready to eat food, especially among urban people, which increases the risk of food-borne diseases. The prevalence of antimicrobial resistance among food-borne pathogens has increased during recent decades. The present study was conducted to isolate various enteric bacterial pathogens from ready to eat food samples sold in local market and to check their susceptibility to commonly used antimicrobials. Material & Methods: For the isolation of enteropathogens, 50 different ready to eat foods were collected from retail market of Chandigarh, India and its periphery. The samples were inoculated on MacConkey agar after serial dilutions and isolates obtained were identified morphologically and biochemically using standard procedures. Their susceptibility to commonly used antimicrobials was checked. Results: A total of 57 bacterial isolates were obtained which included E.coli (42%), Klebsiella spp. (25%), Salmonella spp. (9%), Enterobacter spp. (9%), Pseudomonas spp. (5%), Shigella spp. (4%) and Proteus spp. (4%). The isolates showed highest rate of resistance towards amoxicillin followed by norfloxacin and nalidixic acid. Interpretation & Conclusion: All of the isolated bacteria showed resistance to two or more antibiotics studied. The prevalence of antibiotic resistance among food-borne pathogens is a major threat which may pose difficulty in further treatment.
