Interventions to control the dynamics of antimicrobial resistance from chickens through the environment

This poster, originally presented at the 2023 ReAct Africa and South Centre Conference, presents preliminary findings from the ICARS-supported ENVIRE project in Tunisia. The project aims to reduce the selection and spread of antimicrobial resistance (AMR) in broiler chickens, and its transmission from chicken farms to the environment, and ultimately to humans.

The project focuses on antibiotic-resistant bacteria, specifically ESBL-producing E. coli and other Enterobacteriaceae, and their resistance to antibiotics such as fluoroquinolones and colistin. The project includes multiple on-farm intervention studies to explore practical mitigation strategies. In addition, a quantitative risk assessment model is being developed to evaluate the effectiveness and potential synergistic impacts of these interventions in reducing human exposure to AMR through foodborne, occupational, and environmental pathways.
