On 9 Jun 2022, the Arrell Food Institute of Canada’s University of Guelph awarded veterinary epidemiologist Delia Grace the 2022 Arrell Global Food Innovation Award for Research Innovation. Presented in Toronto during the 5th Arrell Food Summit, on the ‘Future of Food’, the award comes with a CAD100,000 cash prize. Delia Grace is a contributing scientist at the International Livestock Research Institute (ILRI), in Kenya, and professor of food safety systems at the Natural Resources Institute (NRI), University of Greenwich, in the UK.

Delia Grace has produced more than 300 scientific publications, which are notable for their quality as well as their number. Working at the intersection of veterinary, agriculture and food systems, Delia is a recognized global leader in livestock-related food safety, One Health and zoonotic disease issues. Her ground-breaking research has advanced understanding of human diseases spread from animals and the roles of animal-sourced foods in nutrition and was first to identify the heretofore unrecognized but enormous burden of diseases among poor people that are caused by consumption of contaminated foods.

The 9 Jun 2022 award event included a 40-minute presentation by Delia about her journey of several decades to provide an understanding of foodborne disease and how best to manage it. (Scroll down to the bottom of this article to view Delia's livestreamed presentation and following discussion.)

Delia’s work has raised the formerly neglected (‘Cinderella’) issue of food safety in developing countries to the prominence it is afforded today. Her work applies participatory Eco-Health and One Health approaches that must be employed if we are to make progress in addressing the world’s most complex and severe food security issues. A veterinarian and epidemiologist by training, her research teams have employed methodologies spanning community-based approaches at the village level to the analysis of global data.

As noted by the several experts that supported Delia’s nomination for this award, some of which are excerpted below (lightly edited for clarity and brevity), it is difficult if not impossible to do justice to large Delia's body of work, multitude of productive partnerships and many impacts on real-world change. The quantity and quality of Delia’s work can perhaps best be assessed by reviewing a selection of her publications (find below links to just a few examples of her notable works).

Nomination comments from Jimmy Smith, ILRI Director General:
‘Following 5 years as a practicing vet and 5 years working with non-governmental development organizations, over a relatively short period of some 15 years of her international research career, Delia has become a global leader in food safety issues and improved control of emerging and other zoonotic diseases, all with a focus on providing practical, evidenced-based approaches and ways forward suiting the developing world, where the context, and thus options for problem-solving, are so very different from those in the developed world.

‘Delia has an uncanny ability to sift through vast science literature and results to focus on what matters most, to explicate why, and then to articulate that powerfully and concisely for readers of all kinds—from eminent scientists to research leaders to communications staff to lay publics, all of whom receive her careful and respectful attention.'

In my 40-odd years of research and research management, I have found few her equal in eloquently getting to the heart of complex science matters to advance human development.

From Cate Dewey, University of Guelph:
‘Delia appears to have solved the perennial puzzle of how to “close the loop”—to successfully see field research findings go on to inform meaningful behaviour change and to influence health and nutrition policy.'

At each step of the research she not only disseminates knowledge but also measures the impact of knowledge translation and transfer.

From Brian Perry, ILRI and Oxford and Edinburgh universities:

‘Delia is an extraordinary scientist, and extraordinary in many different ways. To say she uses her active mind in a creative and innovative way would be a gross understatement. She thinks fast, she thinks on her feet, and she strays “out of the box” in almost every sentence. . . .

Probably the most exciting scientist I have ever collaborated with.

‘But it is what she has done with these unique personal skills that is so impressive.'

From Michael Taylor, Meridian Institute, Stop Foodborne Illness and former U.S. Food and Drug Administration:
‘Delia is the pre-eminent thought leader in sub-Saharan Africa on food safety and how properly managed animal agriculture can help meet the food security and nutrition needs of African consumers.

I know no other person who has had more impact in improving food safety in Africa.

'She is fearless (she challenges the status quo with a unique blend of force and diplomacy) and her generosity of spirit and uniquely integrative approach to research are as uncommon as they are exemplary.

'Delia stands on the most solid of research foundations but then engages everyone around her in a spirit of collaboration that is empowering of all.'

From John McDermott, former research director at ILRI and the CGIAR Research Program on Agriculture for Nutrition and Health

‘Delia has been at the forefront of research on risk-based approaches to mitigating the substantial food safety risks in informal markets across Africa and Asia.

'Among the research methods she has adapted and combined are classic epidemiological surveys and modelling, risk analysis, participatory research approaches, and socio-economic research on gender and equity and basic cost-effectiveness/benefit analysis.

Delia has played a ‘Hans Rosling’ like role in bringing unappreciated developing country evidence on food safety and One Health to governments, international organizations and development donors.

'The body of research evidence being generated by Delia and her teams is critical to guiding current and future decisions about the development of informal and formalizing markets for perishable foods in low- and middle-income countries with rapidly transforming food systems.

Delia has developed and mentored a great research team of young researchers. Everybody wants to work with Delia, from students to established international researcher leaders.

'Delia’s passion is grounded in a commitment to the ultimate beneficiaries of the research. She understands the perspectives of local consumers, informal butchers, milk hawkers and farmers and she can link their stories with her research.'

Because of her passion for equity, Delia brings a healthy disrespect for expert solutions that fail to critically evaluate assumptions and evidence of their impacts on the poor.
