Prevalence of Multi-Drug Resistance Escherichia coli in Broiler Chicken Meat in Jember, Indonesia

Antibiotic resistance has become one of the global health problems nowadays. Chicken meat is one of the largest food commodities in the world. Escherichia coli (E. coli) is one of the bacteria that is often found in chicken meat. These bacteria are capable of being pathogenic in both animals and humans. This study aimed to determine the prevalence of multidrug-resistant E. coli isolated from broiler chicken meat in the study location. The E. coli utilized in this study were derived from 25 grams of chicken meat obtained from 30 samples procured from six markets within the Jember district. The resistance test method used was Kirby-Bauer with Mueller-Hinton media. The results of the study showed that 100% of chicken meat was contaminated with E. coli. All isolated E. coli from samples in the study were multidrug-resistant. E. coli was 100% resistant to cotrimoxazole and cefixime, 96.67% resistant to chloramphenicol and amoxicillin-clavulanic, 93.3% resistant to tetracycline, 90% resistant to ceftriaxone, and 80% resistant to azithromycin and ciprofloxacin. The minimum resistance profile to 5 types of antibiotics with a multiple antibiotic resistance (MAR) index was between 0.625-1. Thus, the study revealed a high risk of infection associated with the consumption of uncontrolled chicken meat.
