Professor Jebb, who took up the role in 2021, will complete her three-year term of office on 30 June.
Alongside her role with the FSA, Jebb is also a professor of diet and population health at the Nuffield Department of Primary Care Health Sciences at the University of Oxford.
The selection process for the next FSA Chair will led by the Department of Health and Social Care (DHSC) with the recruitment process set to commence shortly. The appointment is made by the secretary of state for health and social care and counterparts in Wales and Northern Ireland.
Reflecting on her nearly three years in the role, Professor Jebb said it has been a “huge privilege” to serve as the chair of such a “fantastic organisation” that conducts “such important work to uphold public health”.
She continued: “I am proud of the work the Board has done to enable the FSA to move beyond the immediate consequences of EU Exit and settle into an organisation focused on the most pressing challenges the UK food system faces today, including initiating a series of important reforms.
“There is still much I want to achieve over the next four months. Our reform programme is urgently needed to enable the FSA to support businesses to do the right thing, deliver efficiencies for the taxpayer and, crucially, to uphold the high food standards we all value.
“Alongside my role as FSA Chair, I have continued to lead a large research team at the University of Oxford, working to develop the evidence base for interventions to prevent and treat obesity and, looking ahead, I am keen to be able to give that my full attention.”
Timothy Riley began his term as deputy chair on 1 January 2024 and will also serve a term of three years.
