Background Antimicrobial resistance (AMR) is a global threat to human and livestock health. Although AMR is driven by use of antimicrobials, it is often attributed to “misuse” and “overuse”, particularly for antibiotics. To curb resistance, there has been a global call to embrace new forms of moral personhood that practice “proper” use, including prescription, dispensing and consumption of antimicrobials, especially antibiotics. This paper seeks to reflect on complex questions about how morality has become embedded /embodied in the AMR discourse as (...) presented in the data collected on antimicrobial prescription, dispensing and use in human and livestock health in Tanzania, primarily focusing on antibiotics. Methods This reflection is anchored on Jarrett Zigon’s morality framework that is comprised of three dimensions of discourse; the institutional, public, and embodied dispositions. The data we use within this framework are derived from a qualitative study targeting human and animal health care service providers and community members in northern Tanzania. Data were collected through 28 in-depth interviews and ten focus group discussions and analysed through content analysis after translation and transcription. In addition, a review of the Tanzania’s National Action Plans on antimicrobial resistance was conducted. Results Application of the framework demonstrates points of convergence and divergence in the institutional morality discourse articulated by the Tanzania National Action Plans, the public discourse and the embodied dispositions/ lived experiences of human and animal health care service providers and community members. We demonstrate that AMR is not just associated with “inappropriate” behaviour on the part of drug prescribers, dispensers, and users but also with shortcomings in health systems and service delivery. Conclusion Antibiotic dispensing and use practices that may be associated with the development of AMR should not be viewed in isolation from the broader health context within which they occur.
