To combat the OneHealth threat of antimicrobial resistance (AMR), the use of antibiotics in agriculture is subject to significant governance-led initiatives to change food system behaviours, including promoting more responsible use of antibiotics on farms through marketlevel interventions. To combat knowledge gaps about how consumers perceive risks associated with antibiotic use and AMR in farming, the current study carried out an in-depth qualitative focus group study incorporating a risk information exposure exercise with food consumers on the island of Ireland (n = 36). Using a theoretical lens of social representation theory, a thematic analysis of the collected data identified how participants made sense of, often new, information on agricultural antibiotic use and AMR. Participants displayed high awareness and concern for AMR but low understanding and misconceptions around AMR transmission from the agri-food sector. Social representations about antibiotics and food and farming systems shaped preferences for a movement away from antibiotics in farming, and in particular, prophylactic use. However, participants acknowledged the role of antibiotics to protect animal health and the integrity of the food supply chain. They debated the lack of a simple fix to antibiotics in the agri-food system and revealed preferences for preventive actions at farm level and supporting actions at market level. The study highlights the need to first tackle low levels of public understanding through effective risk communication including strategies such as targeted message framing and proactive, cross-sector OneHealth awareness campaigns, followed by the introduction of a trusted antibiotic use food labelling system.
