Integrating One Health strategy to mitigate antibiotic resistance in Salmonella: insights from poultry isolates in Southeast Asia

Salmonellosis is a major bacterial foodborne infection worldwide. Inappropriate usage of drugs, especially antimicrobial usage in animal production, is one of the leading issues of antimicrobial resistance (AMR) in Southeast Asia (SEA) countries, especially in treating Salmonella cases. The AMR issue is critical as antimicrobials have been used indiscriminately for the prevention of diseases and it is threatening food safety, especially in poultry production, which carries the largest group of Salmonella as a natural host. In SEA, the range of resistance for penicillin is 13.3% to 89.5% and for tetracycline, it is 25% to 95.7%. Therefore, to develop prompt interventions, the public health authorities must first be aware and have a complete understanding of Salmonella AMR in poultry settings. This review focuses on insight into the epidemiology of Salmonella and information on the current AMR in poultry chickens, as well as the impact on society. It emphasises the need for collaborative efforts to implement the One Health approach to mitigate the AMR of Salmonella in SEA.
