Antibiotic Residues and Antimicrobial Resistant bacteria in the Poultry Value Chain of Two Indian States

• The poultry industry's rapid expansion has made it a significant global meat source, especially in India, which ranks as the eighth largest broiler meat producer. However, severe concerns have arisen over the increasing antibiotic resistance in low and middle-income countries, including India. This study systematically investigated the prevalence of Non-Typhoidal Salmonella (NTS) and Escherichia coli (E. coli) strains, along with their antimicrobial resistance (AMR) profiles, in poultry samples from Assam and Karnataka states in India. We found high prevalence of NTS (26%) and E. coli (53%) in various poultry samples, with substantial regional variations. Assam and Karnataka contribute differently to the overall NTS prevalence, with Karnataka bearing the highest burden (39% versus 14%). The presence of NTS and E. coli in treated water intended for watering poultry raises concerns about the effectiveness of water disinfection methods. Serovar analysis highlights the dominance of Typhimurium, Kentucky, Infantis and other serovars, some exhibiting multidrug resistance (MDR), including resistance to fluoroquinolones. The emergence of antibiotic-resistant strains, including carbapenem-resistant E. coli, presents a potential decline in treatment options. The study highlights the presence of MDR among NTS and stresses the importance of monitoring resistance profiles to devise effective antimicrobial strategies. The study underscores the necessity of collaborative efforts to combat AMR and ensure food safety, health, and wellbeing on a global scale.
