Background: Food borne infection is a serious health problem that results from improper food preparation or cross-contamination. Cross-contamination is produced by contaminated raw foods during further processing, preparation of food by infected person or due to inadequate cleaning of kitchen. Present study is carried out to identify various contaminated spots in the kitchen that may harbour pathogenic bacteria. Methods: Ten kitchens were randomly selected for the study. Samples were collected using sterile cotton swabs from five specific sites which included stove knob, kitchen towel, refrigerator handle, and water tap and kitchen sponge used for washing vessels. Samples collected were processed for isolation and identification of bacteria using blood agar and MacConkey’s agar followed by biochemical tests. Antibiotic susceptibility testing was done using Kirby-Bauer disc diffusion test. Results: Fifty samples collected out of which 32 were found to harbour pathogenic bacteria which included 12 samples of Klebsiella pneumoniae, 7 each with Proteus species & Staphylococcus epidermidis, 3 with Escherichia coli, 2 with Staphylococcus aureus and one with Enterobacter species. Conclusions: This study demonstrated that cross-contamination from the various sites in the kitchen that harbour pathogenic bacteria may contribute to food associated infections. Therefore, frequent cleaning of commonly contaminated areas in the kitchen is essential to prevent vulnerable people from developing food poisoning.
