This has challenged the industry's social licence to operate (SLO).&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Objectives&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;To investigate and elucidate how United Kingdom and Irish racing stakeholders perceive risks to racehorses on race day and how those risks should be managed.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Study Design&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Qualitative analysis of stakeholder perspectives using a constructionist approach.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Twelve stakeholders from veterinary, communication, and regulatory sectors within racing in the United Kingdom and Ireland were interviewed. Semi-structured interviews were analysed using reflexive thematic analysis.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Three key themes were developed ‘Managing Risk, or Managing the Message?’, ‘The Balance between Tradition and Progress on Reducing Risks’, and ‘Attributing Responsibility and the Public Disconnect’. Participants framed risk according to public misunderstanding and effective communication, while others placed increased emphasis on welfare risks and proactive mitigation measures. Some participants viewed ‘accidents’ as unavoidable, others believed that more could be done to minimise avoidable risk. Attribution of responsibility was directed towards various industry stakeholders including trainers, jockeys, regulators and the public. Interviewees noted the industry to be rooted in tradition and slow to adapt to changing expectations.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Main Limitations&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Familiarity between the interviewing researcher and some participants may have encouraged open discussion but could have influenced how responses were framed.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Conclusions&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Stakeholders framed risk in ways shaped by public expectations, culture, tradition, and lived experience.
