Food Safety


World Food Safety Day is celebrated on 7 June every year to raise awareness on food safety and inspire action to help prevent and manage foodborne risks thereby contributing to human health, food and nutrition security, economic prosperity, market access, and sustainable development. The theme this year is Food standards save lives.

The International Livestock Research Institute (ILRI) is commemorating World Food Safety Day 2023 with the launch of a new ILRI-commissioned report, New directions for tackling food safety risks in the informal sector of developing countries, by Spencer Henson, Steven Jaffee and Shuo Wang.

The report will be launched at a webinar on Wednesday 7 June 2023 at 0900 hours EDT / 1300 hours GMT /1600 hours EAT.

Despite ongoing structural changes, the food systems of most low- and lower middle-income countries are still dominated by small-scale processors, grocers, market vendors and food service operators. Unsafe food is a widespread issue in these informal food systems, with national public health implications.

Few countries have coherent strategies to effectively tackle food safety risks in the informal sector. Most of the policy attention and resources now devoted to domestic food safety in the developing world focus on strengthening centralized systems for ‘food control’. 

The authors of the report argue that a different approach is needed to better tackle food safety risks in the informal sector. This would entail local action that is centrally guided, multisectoral action, rebalancing the use of sticks and carrots, and differentiating local strategies and priorities.

Register for the webinar and join us to learn more about the report and hear reactions from food safety experts.

We have also created a landing page on the ILRI website to showcase our food safety projects, publications, stories and key messages. The page also highlights the profiles of ILRI scientists involved in food safety research.

The production of the report, New directions for tackling food safety risks in the informal sector of developing countries, was supported by the CGIAR Research Program on Agriculture for Nutrition and Health (A4NH) and the CGIAR Initiative on One Health. We thank all funders who supported this research through their contributions to the CGIAR Trust Fund.

Antimicrobial resistance is a public health problem worldwide. Bangladesh, like its neighbouring countries, faces many public health challenges, including access to safe food, inadequate food surveillance, as well as increasing antimicrobial resistance.

A new study published in Antibiotics (Mar 2023) investigated bacterial contamination and the antimicrobial resistance profile of pathogens in marketed food in Bangladesh. The study also explored barriers to reducing antimicrobial resistance in the country.

The study was carried out by researchers affiliated to the Bangladesh Agricultural University, the Bangladesh Department of Livestock Services, the Bangladesh Livestock Research Institute, the International Livestock Research Institute, the Swedish University of Agricultural Sciences, Uppsala University and the University of Greenwich.

The researchers collected 366 tomatoes, 359 chicken and 249 fish samples from 732 vendors in traditional markets in urban, peri-urban and rural areas in Bangladesh, as well as from 121 modern retails in Dhaka capital to analyse Vibrio cholerae and Escherichia coli in fish, Salmonella in chicken, and Salmonella and E. coli in tomatoes.

Antibiotic susceptibility against 11 antibiotics was tested using a disc diffusion test and interpreted by an automated zone inhibition reader.

A qualitative study using key informant interviews was also conducted to explore antimicrobial use and antimicrobial resistance reduction potential in Bangladesh.

They found E. coli in 14.21% of tomatoes and 26.91% of fish samples, while 7.38% of tomatoes and 17.27% of chicken were positive for Salmonella, and 44.98% of fish were positive for Vibrio cholerae.

About 70% of all isolated pathogens were multidrug resistant, that is, they were resistant to three or more antibiotic groups.

Qualitative interviews revealed an inadequate surveillance system for antibiotic use and antimicrobial resistance in Bangladesh, especially in the agriculture sector.

To be able to fully understand the human health risks from bacterial hazards in the food and the antimicrobial resistance situation in Bangladesh, the authors of the study propose that a nationwide study with a One Health approach be conducted, including antimicrobial resistance testing and assessment of antimicrobial use and its drivers.

The study was supported by the CGIAR Research Program on Agriculture for Nutrition and Health, the CGIAR Initiative on Resilient Cities and the CGIAR Initiative on One Health.

The World Health Organization estimates that every year, 600 million people become ill and many die because of unsafe food. Up to 38% of those affected are children under five years of age, and 53% were people living in low- and middle-income countries.

To address this gap, the Evidence and Action Towards Safe, Nutritious Food (EatSafe) project recently organized an EatSafe Innovation Challenge aimed at encouraging the development of food safety solutions or safer food products towards improving food safety in traditional markets where most consumers in low- and middle-income countries access their food.

On Tuesday 13 December 2022, the EatSafe project will host a webinar to highlight the importance of innovative solutions in food safety, and their applicability to low- and middle-income countries, specifically in traditional markets and along the food value chain.

This webinar is the second part of a series on innovative approaches to food safety. The first webinar, held in January 2022, featured consumer-centred approaches to food safety research.

In this second webinar, speakers will share on the application, implementation and practice of innovative solutions for food safety, including highlights from finalists of the EatSafe Innovation Challenge.

Below are details of the hour-long webinar and how to register.

Date: Tuesday 13 December 2022

Foodborne disease is a significant global health problem, with low- and middle-income countries disproportionately affected. Given that most fresh animal and vegetable foods in these countries are bought in informal food systems, much of the burden of foodborne disease here is also linked to informal markets.

Developing estimates of the national burden of foodborne disease and attribution to specific food products will inform decision-makers about the size of the problem and motivate action to mitigate risks and prevent illness.

A new research study, published in Frontiers in Sustainable Food Systems (Nov 2022), provides estimates for the burden of foodborne disease caused by selected hazards in Burkina Faso and Ethiopia and attribution to specific foods.

Country-specific estimates of the burden of disease in 2010 for Campylobacter spp., enterotoxigenic Escherichia coli, Shiga-toxin producing E. coli and non-typhoidal Salmonella enterica were obtained from the World Health Organization (WHO) and updated to 2017 using data from the Global Burden of Disease study.

Attribution data obtained from WHO were complemented with a dedicated Structured Expert Judgement study to estimate the burden attributable to specific foods. Monte Carlo simulation methods were used to propagate uncertainty.

The burden of foodborne disease in the two countries in 2010 was largely similar to the burden in the region except for higher mortality and disability-adjusted life years due to Salmonella in Burkina Faso.

In both countries, Campylobacter caused the largest number of cases, while Salmonella caused the largest number of deaths and disability-adjusted life years.

In Burkina Faso, the burden of Campylobacter and enterotoxigenic E. coli increased from 2010 to 2017, while the burden of Salmonella decreased.

In Ethiopia, the burden of all hazards decreased. Mortality decreased relative to incidence in both countries.

In both countries, the burden of poultry meat (in disability-adjusted life years) was larger than the burden of vegetables.

In Ethiopia, the burdens of beef and dairy were similar, and somewhat lower than the burden of vegetables.

The burden of foodborne disease by the selected pathogens and foods in both countries was substantial.

Uncertainty distributions around the estimates spanned several orders of magnitude.

This reflects data limitations, as well as variability in the transmission and burden of foodborne disease associated with the pathogens considered.

Scientists from the International Institute for Environment and Development (IIED) and the International Livestock Research Institute (ILRI) have published a new study that explores how the safety of milk and dairy products is understood and managed within the informal dairy sector of Guwahati, the largest city in Assam, northeast India.

The study, published in the journal Cogent Food & Agriculture (Oct 2022), contributes to a growing body of literature that questions negative assumptions about food safety in informal markets, and seeks to understand how access to safe and healthy food for all is, or can be, achieved in these markets.

The study combined a literature review of the informal dairy sector in Assam and India with a field survey and key informant interviews.

The survey of 113 producers, intermediaries, retailers, traditional processors and consumers, provides insights into how people think about the safety of milk, and the everyday practices they employ to mitigate food safety risks when trading and consuming dairy products.

The findings suggest that, in the absence of formal guarantees of quality and safety, consumers’ cultural practices and producers’ and traders’ knowledge likely reduce the risks of consuming raw milk.

Despite the informal dairy sector receiving little direct government support in India, the study found that at the state level, there has been some cooperation between government officials, small-scale producers and informal traders.

The authors conclude that the absence of adverse relations between these groups, together with proactive attempts at collaboration, could inform the approaches of other Indian states to food safety governance, and are a positive foundation for future improvements to food safety in Assam’s dairy sector.

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.

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.

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 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.
