Abstract: Milk and dairy products harbor bacteria that are resistant to one or more antimicrobial drugs. This study was conducted to determine the antimicrobial susceptibility pattern of E. coli isolated from milk and dairy products collected randomly from Chennai. A total of 567 samples comprising raw milk, pasteurized milk, dairy products viz., channa based sweets, khoa based sweets, fermented dairy products, concentrated or partially desiccated dairy products, heat and acid coagulated dairy products, frozen dairy products and other dairy products like butter, cheese were processed to isolate E. coli and to study their antibiotic susceptibility pattern. Out of 567 samples, 34 E. coli were isolated and its phenotypic resistant profile was 94.11 per cent for penicillin-G and cephalothin followed by ampicillin (88.23%), amoxicillin (82.35%) and clindamycin (76.47%). Among these 34 E. coli isolates, 28 (82.35%) were multiple drug resistant (MDR). This alarms the need for devising appropriate strategies to prevent the spread of resistance.
