Successful symposium on AMR in Livestock Production in a One Health Context

The OECD-CRP Symposium on AMR in Livestock Production in a One Health Context was held in Edinburgh on 22-24 May 2023.

The magnitude and gravity of the antimicrobial resistance (AMR) health crisis has been stressed by national and international commentators and it is clear that there is an imbalance between the attention given to management of antimicrobial use (AMU) and AMR in clinical settings compared to that in livestock production.  

Since the latter could amount to more than half the global use of antimicrobials, it is important to understand the drivers of their use and the likely health consequences, both direct and indirect. 

This symposium, sponsored by the OECD's Co-operative Research Programme, focused on specific gaps in our understanding of AMU in livestock systems and the consequences for AMR, approaching the problem from a One Health perspective.  


  1. to review what we do/do not know about AMU across terrestrial livestock and aquaculture, as well as the effects on AMR;
  2. to identify the key barriers (technical, economic, behavioural, political) to interventions to modify AMU;
  3. to review the modelling methods that allow the approximation of AMU and AMR and impacts of different interventions;
  4. to set this knowledge in the broader One Health agenda of science policy communication and curriculum development;
  5. to consider priority policy interventions and strategies.

Successful models of One Health working

The event was organised by Prof Dominic Moran and Carys Redman-White in the Global Academy of Agriculture and Food Systems at the University of Edinburgh. 

It was structured as a 3-day meeting combining formal presentations (keynotes and focused sessions) covering the topics above and exploring successful models of One Health working for policy.  This element involved input of experience from University of Edinburgh projects including the Edinburgh AMR Forum, EPIC, and SEBI-L. 

The ultimate aim is to develop a network for ongoing collaborative projects and expertise to deliver impact in terms of advice to relevant international bodies (WOAH, FAO and WHO) and national governments seeking guidance for implementation of their AMR action plans (NAPs).
