The rapid transformation of food systems is creating unintentional infectious disease risks that will need to be addressed through effective coordination between agricultural and public health sectors, a new review study says.

A food system includes all the aspects of feeding and nourishing people: growing, harvesting, packaging, processing, transporting, marketing and consuming food.

The review, published in Lancet Planetary Health (Sept 2022), explored how intensification of agricultural production and increasing complexity of food supply chains, particularly in low-income and middle-income countries, change the risks and relative burdens of infectious diseases.

The review covered four case studies:

  • vector-borne disease in irrigated agriculture;
  • zoonotic diseases in livestock value chains;
  • food safety; and
  • antimicrobial resistance associated with food systems. 

For each case study, the authors asked three questions:

  1. What aspects of food system transition are creating unintentional infectious disease risks?
  2. What solutions might exist for these problems?
  3. How would they require better coordination of agricultural and public health policy and practice?

Food systems in transition are characterized by intensification and diversification of food production, as an increasingly urban and more wealthy population demands different diets.

The review showed that successfully addressing the challenges of evolving food systems calls for constructive dialogue between agricultural and public health sectors.

Such a cross-sectoral approach recognises the costs and benefits of disease-reducing interventions and seeks win–win solutions that are most likely to attract broad policy support and uptake by food systems.

For areas such as antimicrobial resistance, it is important to identify the potential agricultural and health outcomes of agricultural interventions to reduce health risks.

Informal milk trading in peri-urban Nairobi plays a key role in supporting both livelihoods and nutrition, particularly among poor households. Gender dynamics affect who is involved in milk trading and who benefits from it.

To better understand gendered constraints and opportunities in informal, peri-urban dairy marketing, scientists from the International Livestock Research Institute and the International Food Policy Research Institute conducted a qualitative study in 2017 with 45 men and 50 women milk traders in Dagoretti, a peri-urban area in Nairobi, Kenya. The study is published in Gender, Technology and Development (27 Jun 2022).

The findings show that milk trading is more lucrative for older men than for women and younger men among the respondents. The study delves into the reasons behind the observed differences in the experiences of women and men as informal milk traders. The study also discusses the implications of the findings for interventions aimed at enhancing the sustainability and equity of the dairy sector.

To commemorate this year’s World Food Safety Day (7 June) under the theme Safer food, better health, the International Livestock Research Institute (ILRI) has launched an online food safety campaign and landing page to showcase its collaborative research on risk-based approaches to improving food safety in low- and middle-income countries.

Better management of foodborne diseases could save nearly half a million lives a year and safeguard the livelihoods of over one billion small-scale livestock producers.

ILRI’s approach to food safety research is based on risk analysis. We identify the hazards in food and build the capacity of policymakers to understand risk-based approaches.

Policy will be more effective and efficient if based on actual risk to human health rather than the presence of hazards. ILRI’s approach is therefore to generate research evidence and develop solutions to improve the safety of animal products in informal food markets.

Visit the landing page to read key food safety messages as well as the latest food safety news from ILRI and information on projects and selected publications. You will also find the profiles of ILRI scientists involved in food safety research.

Join the online conversations by following the hashtags #FoodSafety, #SafeFood and #WorldFoodSafetyDay.

Towards enhancing food safety in East Africa, the International Livestock Research Institute (ILRI), the Food and Agriculture Organization of the United Nations (FAO) and the Inter-University Council for East Africa (IUCEA) have been working with food safety experts from universities in the East African Community to develop benchmarks for a Bachelor of Science program in food safety.

As part of this endeavour, a workshop to finalize the curriculum benchmark process was held on 22–24 March 2022 in Kampala, Uganda.

The meeting brought together 21 food safety experts to develop the expected learning outcomes of the curriculum and align the learning outcomes with the main and supportive courses derived from a stakeholder engagement exercise.

The outputs of the group and plenary discussions will be used to draft a benchmark report which will be validated and finalized according to IUCEA processes.

The workshop was funded by CGIAR donors, FAO (Lloyd’s Register Foundation), the CGIAR One Health Initiative, the ILRI-led Capacitating One Health in Eastern and Southern Africa (COHESA) project and IUCEA.

The workshop report may be accessed via the link below.

The rapid evolution of global food safety systems in response to population growth, urbanization, climate change and other socio-economic factors poses many food safety challenges.

Globally, unsafe food causes an estimated 600 million illnesses and 420,000 deaths annually, with Africa disproportionately bearing the highest burden of foodborne diseases.

To effectively tackle the challenge of foodborne diseases in Africa, a team of scientists from the International Livestock Research Institute (ILRI) and Ohio State University has proposed the use of risk-based and One Health approaches.

These approaches to food safety management were put forward in a presentation titled Better food safety solutions in Africa: Understanding the complex social, economic and policy perspectives. The presentation was given at the 37th World Veterinary Association Congress held in Abu Dhabi, United Arab Emirates on 29–31 March 2022.

The main foodborne hazards in the African context were discussed, with local and continental examples of food safety initiatives aimed at reducing the burden of foodborne disease and improving public health. Examples of action research and political decision-making on food safety at the continental level were also described.

In light of the complex nature of global and African food safety systems, food safety interventions to reduce foodborne diseases need to be well designed and coordinated, the researchers say.

Effective communication and constructive dialogue on inclusive ways forward between policy-makers and informal milk vendors can help to bridge the gap between policy and reality in Kenya’s informal milk sector, according to a new research study published in Development Policy Review (May 2022).

Around 80% of milk in Kenya is sold informally, providing livelihoods and contributing to the food security and nutrition of low-income consumers. Government policy, however, is focused on formalization—primarily through licensing and pasteurization—with enforcement via fines, confiscation of milk or closing the premises of informal actors.

The study, which was carried out by researchers from the International Institute for Environment and Development (IIED) and the International Livestock Research Institute (ILRI), sought to better understand if, and why, Kenya’s informal milk sector and regulatory system are disconnected from one another and how the policy–reality gap might be better bridged.

To understand the nature and performance of Kenya’s informal milk markets and their governance, the authors used surveys with informal market players and key informant interviews. Fieldwork was carried out in Nairobi in late 2018.

The study found that milk safety and quality matters to all actors in informal milk value chains. The trust-based system used is effective in moderating behaviour and assessing and prioritizing quality and safety. 

However, government policy was found not to accomplish the stated goal of formalization, with low levels of licensing among informal actors. Pasteurization was not rewarded in the market and there was some evidence of sub-optimal pasteurization processes being undertaken to satisfy regulators. 

These findings point to a gap between the reality of Kenya’s informal milk sector and its policy and regulatory system.

This gap is seen in the form of adversarial relationships between regulators and informal actors, and unnecessary transaction costs, missing opportunities for enhancing livelihoods, food safety, and food security. 

The authors of the study therefore recommend that new approaches build on and consider existing approaches taken by actors in informal food markets to ensure food safety and quality.

The COVID-19 pandemic has underscored the need to strengthen national surveillance systems to protect a globally connected world.

In low-income and middle-income countries, zoonotic disease surveillance has advanced considerably in the past two decades. However, surveillance efforts often prioritize urban and adjacent rural communities.

Communities in remote rural areas have had far less support despite having routine exposure to zoonotic diseases due to frequent contact with domestic and wild animals, and restricted access to health care. Limited disease surveillance in remote rural areas is a crucial gap in global health security.

Although this point has been made in the past, practical solutions on how to implement surveillance efficiently in these resource-limited and logistically challenging settings have yet to be discussed.

A new paper in Lancet Global Health (Apr 2022) highlights why investing in disease surveillance in remote rural areas of low-income and middle-income countries will benefit the global community and review current approaches.

Using semi-arid regions in Kenya as a case study, the authors’ viewpoint provides a practical approach by which surveillance in remote rural areas can be strengthened and integrated into existing systems.

The viewpoint represents a transition from simply highlighting the need for a more holistic approach to disease surveillance to a solid plan for how this outcome might be achieved.

Transformation of food systems is key to addressing malnutrition, non-communicable diseases, climate change and other global health challenges of the 21st century, a new research study says.

The study, published in the American Journal of Clinical Nutrition (Jan 2022), presents a synthesis of the 22nd Annual Harvard Nutrition Obesity Symposium held in June 2021 entitled ‘Global Food Systems and Sustainable Nutrition in the 21st Century’.

The symposium was a collaboration between the Nutrition Obesity Research Center at Harvard and the Harvard Medical School Division of Nutrition and was organized ahead of the United Nations Food Systems Summit (UNFSS) in September 2021.

A food system includes all the aspects of feeding and nourishing people: growing, harvesting, packaging, processing, transporting, marketing and consuming food.

The authors of the study note that the nutrition and health communities have a significant role to play in ensuring that food systems produce affordable, nutritious and safe food in an equitable manner that safeguards environmental sustainability.

“Food systems need to be better managed and governed to ensure that food system transformation is redesigned to improve nutrition and health, ensure environments are sustainable and resilient, promote fair and equitable livelihoods, and mitigate climate change,” the authors state.

CGIAR-affiliated scientists Delia Grace and Namukolo Covic are among the co-authors of the study.

Delia Grace is professor of food safety systems at the Natural Resources Institute of the University of Greenwich and joint-appointed scientist at the International Livestock Research Institute (ILRI).

Namukolo Covic is the ILRI Director General’s Representative to Ethiopia and previously served as senior research coordinator for the CGIAR Program on Agriculture for Nutrition and Health (A4NH), led by the International Food Policy Research Institute (IFPRI).
