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.
