A new study published in Frontiers in Veterinary Science (February 2021) has documented the governance structure of the Nairobi pork value chain and the challenges faced by traders and how these impact on food safety.

The pork food system in Nairobi is a growing livestock sub-sector which serves as a source of food and livelihood to the city’s inhabitants. To better understand how this food system works, the study mapped the key pork value chains, assessed their governance and operational challenges and analysed the potential impacts on food safety management.

A mixed-method approach was used to collect both qualitative and quantitative data on animal movements, product flows, stakeholder interactions, perceptions on system governance, operational challenges faced, business operations and market share.

A thematic analysis was also carried out to identify the themes that provide understanding on governance, challenges and food safety practices in the pork system.

The predominant pork value chains identified were the ‘large integrated company’ profile which accounted for 83.6% of marketed pork and the privately owned, small-scale local independent abattoirs accounting for 16.4%.

The study documented a number of challenges associated with governance of the pork value chains including inadequate enforcement of existing regulation, dominance of pig traders and lack of association at all nodes of the system.

The traders themselves were also beset by several challenges that could have a bearing on food safety management; these included inadequate slaughter facilities, lack of capital for upscaling, lack of training on slaughterhouse hygiene and lack of knowledge on how to manage pig diseases.

These findings provide useful insights into the structure of the pork system supplying the city of Nairobi. Policymakers and food safety researchers can use this framework to investigate and further develop the pork industry. The framework can also be used to develop appropriate programs for food safety and control of pig diseases.

The study is an output of a collaborative project on the epidemiology, ecology and socio-economics of disease emergence in Nairobi that was carried out by scientists from the International Livestock Research Institute, the Kenya Directorate of Veterinary Services, Royal College London, the University of Liverpool and the University of Nairobi.

Animal health leaders and researchers from the Global Burden of Animal Diseases (GBADs) program have secured US$ 7 million from the Bill & Melinda Gates Foundation and the UK’s Foreign, Commonwealth and Development Office to roll out a framework on measuring animal health burdens and their impacts on human lives and economies.

The information provided by the GBADs program will guide public policy and private sector strategy, contributing to improve animal health and welfare more effectively. It will also be a basis for further academic research.

Across the world, livestock production and aquaculture are critical to human nutrition and health. These animals play critical roles in society, providing income and food, but also clothing, building materials, fertilizer and draught power. However, the presence of endemic and emerging diseases, as well as other factors, negatively impact them, jeopardizing their contributions.

Every year, hundreds of millions of dollars are invested globally on disease mitigation in order to improve livestock health and productivity. Yet, a systematic way to determine the burden of animal disease on the health and wellbeing of people is not available.

It is still unknown how the burden is apportioned between smallholders and the commercial sector, or across regions and gender. Consequently, decision-makers lack the information to accurately assess whether their investments target the animal health issues that have the most significant impact on human wellbeing.

The GBADs program, led by the University of Liverpool, the World Organisation for Animal Health (OIE) and a partnership of international institutions, will enable the examination of animal health and the disease burden from a different perspective.

By assessing the global burden in economic terms, the program will help identify the individuals and communities which are the most impacted, demonstrating how animal health is intrinsically linked to agricultural productivity, smallholder household income, the empowerment of women and the equitable provision of a safe, affordable, nutritious diet.

Professor Dame Janet Beer, Vice Chancellor, University of Liverpool, said: ‘The GBADs program is a key part of our commitment to deploying our research capacity towards the welfare of humankind. The GBADs program is crucial in building a world with zero hunger, good health and equality for all, an urgent mission in which we are proud to play our part. We are grateful for the support of the Bill & Melinda Gates Foundation and the UK’s Foreign, Commonwealth and Development Office, who are supporting this work in partnership with the OIE. Together, we will realise a brighter future for animal and human well-being.’

Dr Monique Eloit, OIE Director General, said: ‘It is more evident now for everyone that animal health and public health are interconnected and play an essential role in building a sustainable and healthy planet, especially if we succeed in incorporating the environmental and socioeconomic components.’

The international institutions partnering with the University of Liverpool and OIE in the GBADs program are the Commonwealth Scientific and Industrial Research Organisation; the University of Guelph; the Institute for Health Metrics and Evaluation at the University of Washington; the International Livestock Research Institute; Murdoch University; Sciensano; Washington State University; the University of Zurich; and the Food and Agriculture Organization of the United Nations. The program has also received funding from the Brooke Foundation and the Australian Centre for International Agricultural Research.

The International Livestock Research Institute will play a key role in investigating and applying approaches to improve our understanding of the burden of animal disease in farming systems in Ethiopia. This work will act as a case study, providing insights relevant to other settings and methods that can be used elsewhere. Understanding the scale and nature of how animal disease impacts livelihoods and economies is key, but this information then needs to be used to better advise governments and other investors in livestock and disease control. Therefore, tools and approaches will be developed to ensure that animal health policies are rational and informed by evidence.

The new partnership will support the implementation of the GBADs program. In a world where 1.25 billion people work in agriculture, the program will have a positive impact on the Sustainable Development Goals contributing to Zero Hunger; Good Health and Well-being; Gender Equality; Decent Work and Economic Growth; and Responsible Consumption and Production.

The World Health Organization has declared that antimicrobial resistance is one of the top 10 global public health threats facing humanity. It requires urgent multisectoral action in order to achieve the Sustainable Development Goals.

Improving evidence for action is crucial to tackle this global challenge. The number of interventions for antimicrobial resistance is increasing but current research has major limitations in terms of efforts, methods, scope, quality and reporting.

Moving the agenda forward requires an improved understanding of the diversity and feasibility of interventions, the factors that influence their effectiveness, and the ways in which individual interventions might interact to affect actions against antimicrobial resistance in different contexts.

As part of efforts to strengthen the global governance of antimicrobial resistance, a group of international research experts is advocating for an evidence-based approach to the challenge through the creation of an international One Health platform for online learning that will synthesize the evidence for actions on antimicrobial resistance into a fully accessible database.

The researchers discuss this One Health learning approach to antimicrobial resistance in an article published in Lancet Infectious Diseases (1 Dec 2020), noting that there are currently significant limitations in terms of availability of context-specific evidence on appropriate actions to tackle antimicrobial resistance.

The proposed platform will also offer new scientific insights into the design, implementation, evaluation and reporting of the range of interventions relevant to addressing antimicrobial resistance.

“Fundamental gaps in knowledge hinder action against antimicrobial resistance, but the limitations of research into interventions for antimicrobial resistance serve as even bigger obstacles,” the authors say.

The range of interventions to tackle antimicrobial resistance is wide: from simple actions to complex ones, from regulatory to behavioural approaches, and from those focusing on prevention of infection to those focusing on responsible use of antimicrobials. Therefore, it is crucial to consolidate an evidence-based approach to the challenge.

The authors also note that the open access One Health learning platform will be useful to health-care professionals, public health practitioners, policymakers, industries and consumer groups.

“Ultimately, this will contribute to building societal resilience to this central challenge of the 21st century.”

The COVID-19 pandemic and climate change represent converging challenges to which no continent, country or community is immune. Aligning the global recovery from COVID-19 with our response to climate change offers a triple win: protect public health, promote a sustainable economy and preserve our planet.

This is according to a new report by the Lancet Countdown initiative, an international, multi-disciplinary research collaboration that tracks the evolving public health impacts of climate change and publishes its findings annually in The Lancet medical journal ahead of the United Nations climate change negotiations.

The Lancet Countdown 2020 report, launched on 3 December 2020, tracks the links between health and climate change across 43 indicators in five domains:

  • climate change impacts, exposures and vulnerabilities;
  • adaptation, planning and resilience for health;
  • mitigation actions and health co-benefits;
  • economics and finance; and
  • public and political engagement.

The report represents the findings and consensus of the 35 leading academic institutions and United Nations agencies that make up the Lancet Countdown initiative, and draws on the expertise of climate scientists, geographers, engineers, experts in energy, food and transport, economists, social and political scientists, data scientists, public health professionals and doctors.

Among the report’s co-authors is Delia Grace, professor of food safety systems at the Natural Resources Institute, University of Greenwich and contributing scientist at the International Livestock Research Institute.

Food safety has never featured prominently on Africa’s development agenda. When it is an issue, typically the focus has been on high-value food items produced for export, while food safety in domestic markets has been largely neglected, both by governments and development partners. This must change. Recent research has shown that the health and economic consequences of foodborne diseases in Africa are significant and growing, as urbanization and income growth prompt dietary changes that increasingly expose consumers to food safety hazards.

The coming decade is critical. A ‘business as usual’ approach to food safety, involving a combination of post-outbreak firefighting and fragmented regulatory and ad hoc interventions, will do little to check the threats posed by unsafe food in many African countries. The good news is that many of these problems can be controlled and their costs reduced. A combination of incremental and systematic measures, well within the capacity of most governments, can flatten the curve of foodborne illness.

Until recently, research on foodborne diseases was mostly limited to high-income countries. Research and public health interventions in poorer countries largely focused on the so-called big three—tuberculosis, HIV/AIDS and malaria—and on maternal and child mortality. Yet, recent epidemiological research from the World Health Organization shows the costs of neglecting foodborne diseases in developing countries. Worldwide, the global health burden of foodborne diseases is on par with the big three. The young, old, malnourished and poor are disproportionately impacted and children under five years of age are especially vulnerable.

Globally, Africa south of the Sahara and emerging Asia have the highest incidence of and death rates from foodborne diseases. Yet while the incidence rates of the two regions are comparable, Africa’s estimated death rate is nearly four times higher. The reasons for that difference are not fully understood, but the prevalence of endemic ailments and poor diagnostic and treatment options probably account for much of it. Drawing on data from the World Health Organization and other recent sources, we estimate that Africa experiences around 135 million cases of foodborne diseases and 180,000 foodborne disease-related deaths per year. Microbial pathogens—especially Salmonella spp., toxigenic Escherichia coli, norovirus and Campylobacter spp.—account for about 80% of Africa’s foodborne disease burden.

The economic consequences of foodborne diseases in Africa are correspondingly severe. A recent World Bank study estimated the productivity losses alone attributed to unsafe food within Africa at $20 billion in 2016 and the cost of treating these illnesses at an additional $3.5 billion. These costs are heaviest in larger, middle-income countries such as South Africa, Nigeria and Egypt, yet are also significant elsewhere. Overall, the relative economic burden of foodborne diseases is higher for African countries than for developing countries elsewhere.

Both the health and economic consequences of foodborne diseases in Africa are likely to grow as the continent develops. In low-income countries, food is typically produced close to the point of consumption and undergoes limited transformation. Starchy staples such as cassava, maize and rice predominate. Traditional processing techniques dominate and are often fairly effective at reducing risk. As they develop and urbanize, countries experience rapid shifts in diet and towards more intensified agriculture. Such transitions typically lead to increased consumption of fresh produce and animal-sourced foods and a lengthening of food supply chains. Yet much of this perishable food continues to be handled and distributed through informal channels, creating potentially multiple points for food hazards to develop. In these transitioning food systems, the official regulatory apparatus is often overwhelmed by the breadth and depth of emerging challenges.

Until very recently, domestic food safety programs in Africa have been few and poorly funded. By contrast, literally hundreds of projects supported by trade partners or development agencies have sought to address international trade-related food safety problems. These have been beneficial and have helped to push Africa’s trade in safety-sensitive foods such as fish, fresh fruit and vegetables from $3.8 billion in 2001 to $16.1 billion in 2017. But overall, the available evidence suggests that the trade-related costs associated with unsafe food in African countries are small compared to the domestic public health costs and productivity losses. In fact, we estimate the ratio between domestic and trade-related costs is likely to be on the order of 40 to 1, suggesting that the predominant attention of policymakers on the trade impacts of food safety has been deeply misguided.

African countries must implement better domestic food safety policies and support them with needed investment. But this, in itself, will not be enough to give them the upper hand against foodborne diseases. What they need is nothing less than a food safety paradigm shift. The traditional regulatory model, imported from high-income countries, centres on enforcement through regular inspection of food facilities and product testing, with set legal and financial penalties. This model is ill-suited to food systems in Africa, where smallholder farmers, micro- and small enterprises and informal food channels predominate, surveillance and inspection mechanisms can be weak and court procedures challenging and slow. It introduces an antagonistic and often unproductive relationship between government and the private sector as regulator versus regulated.

A better approach is to think of food safety as a shared responsibility between food business operators, consumers and the government. In this model, governments set forth a vision, convene stakeholders and offer a diverse set of policy instruments to involve, incentivize and leverage the actions of key value chain actors. Instead of being the ‘official food control’ authority, governments should act as facilitators encouraging investments and behaviour change. Experimentation and flexibility will be critical.

There are no quick fixes to Africa’s food safety challenges. They require a comprehensive approach that focuses on improving food safety awareness, practices and governance. Foundational investments will be needed in people, infrastructure and institutions. Addressing these issues will require sustained attention from technical agencies and government ministries as well as donors. It will require broader interventions to improve access to quality public health services, clean water and sanitation and improved agricultural productivity. It will require, in short, a commitment commensurate to the scale of the problem. It is also likely, as in other parts of the world, that improvements will ultimately be driven by better-aware consumers demanding food safety and eliciting responses from public sector and food suppliers. Recognizing that is a good place to start.

The current coronavirus disease (COVID-19) pandemic has brought into sharp focus the interconnectedness of people, animals and the environment and how this can contribute to the spread of disease.

One Health is a concept that recognizes that the health and well-being of people is intricately linked to the health of animals and the environment. For this reason, disease outbreaks are best tackled through a One Health approach that harnesses the collaborative efforts of multiple disciplines and sectors. This is especially so for zoonotic diseases that are spread between animals and people. One Health is also useful for addressing other public health issues such as antimicrobial resistance and food safety. 

One Health is not a new concept, but it has become more important in recent years. This is because many factors have changed interactions between people, animals and the environment. These changes have led to the emergence and re-emergence of zoonotic diseases.

The International Livestock Research Institute (ILRI) has an established record of collaborative One Health research in Africa and Southeast Asia. To mark One Health Day coming up next week on 3 November, we bring you highlights of some One Health research initiatives by ILRI and partners.

Ecosystem approaches to the better management of zoonotic emerging infectious diseases in Southeast Asia

This project worked directly with over 100 actors involved in managing zoonotic emerging infectious diseases across eight multi-disciplinary teams in Cambodia, China, Indonesia, Laos, Thailand and Vietnam. The project increased the capacity of researchers and policy implementers to use One Health approaches for better control of zoonotic diseases. The project also produced various research outputs and increased understanding of the teams’ knowledge, attitudes and practice in relation to One Health and how this approach could lead to better health outcomes for people, animals and the environment.

One Health Regional Network for the Horn of Africa

This project aims to improve the health and wealth of the people of the Horn of Africa by developing a regional network of individuals and organizations that can undertake high quality research into the link between people’s health and that of livestock and the environment. The project builds capacity to undertake basic and applied research in One Health through training programs and research placements for both research and non-research staff from participating institutions.

One Health Research, Education and Outreach Centre in Africa

The One Health Research, Education and Outreach Centre in Africa was launched barely a week ago (on 22 October 2020) and is hosted at ILRI’s Nairobi campus. Its goal is to improve the health of humans, animals and ecosystems through capacity building, strengthening of local, regional and global networks and provision of evidence-based policy advice on One Health in sub-Saharan Africa. It has four research themes: control of neglected tropical zoonotic diseases; emerging infectious diseases; food safety and informal markets; and prevention and control of antimicrobial resistance. The centre is currently supporting the Government of Kenya’s national response to the COVID-19 pandemic through COVID-19 testing in ILRI’s bioscience laboratories.

One Health Units for Humans, Environment, Animals and Livelihoods

This project applies a One Health approach to enhance the well-being and resilience of vulnerable communities in pastoralist and agro-pastoralist areas of Ethiopia, Kenya and Somalia. The project brings together professionals in human and animal health and the environment to achieve better access to human and veterinary health services and sustainable natural resource management.

Open Access Week 2020 banner. Open with purpose: Taking action to build structural equity and inclusion. October 19-25.

International Open Access Week is an opportunity to raise awareness about open access publishing of research outputs to enable their universal online accessibility. Research outputs are wide-ranging and include articles in peer-reviewed journals, books, book chapters, conference proceedings, infographics, presentations, posters, reports, theses and videos.

The theme of this year’s Open Access Week (19–25 October) is ‘Open with purpose: taking action to build structural equity and inclusion’.

The Animal and Human Health program of the International Livestock Research Institute (ILRI) seeks to effectively manage or eliminate livestock, zoonotic and foodborne diseases that matter to the poor through the generation and use of knowledge, technologies and products, leading to higher farmer incomes and better health and nutrition for consumers and livestock.

To celebrate Open Access Week 2020, we bring you a curated selection of recently published open access outputs authored and co-authored by scientists from ILRI’s Animal and Human Health program from across our research portfolio on antimicrobial resistance, food safety, One Health and zoonotic diseases.

A new research report (Oct 2020) by scientists from the International Institute for Environment and Development (IIED) and the International Livestock Research Institute (ILRI) reviews the status and policy contexts of informal milk markets in Kenya, Tanzania and Assam (India) to better understand the opportunities for a policy innovation based on training and certification to overcome market access barriers for sellers of informal milk by improving the health and safety practices of informal milk traders, thereby addressing policymakers’ concerns. It is based on an extensive review of available literature and a small number of expert interviews and contributions.

The effects of COVID-19 have gone undocumented in nomadic pastoralist communities across Africa, which are largely invisible to health surveillance systems despite their significance in the setting of emerging infectious disease.

A new research paper in the American Journal of Tropical Medicine and Hygiene (online first 10 Sept 2020) exposes these landscapes as a ‘blind spot’ in global health surveillance, elaborates on the ways in which current health surveillance infrastructure is ill-equipped to capture pastoralist populations and the animals with which they coexist, and highlights the consequential risks of inadequate surveillance among pastoralists and their livestock to global health.

As a platform for further dialogue, the authors of the paper also present solutions to address this gap. These include the development of an integrated One Health surveillance system that links pastoralists, their livestock and overlapping wildlife populations with centralized disease reporting. Community-based syndromic surveillance and participatory epidemiology would also improve early detection and reporting of disease outbreaks for more timely control interventions.

World Zoonoses Day is commemorated on 6 July every year to mark the day in 1885 when Louis Pasteur successfully administered the first vaccine against rabies, a deadly zoonotic disease. The day is also an occasion to raise awareness of the risk of zoonoses, infectious diseases that can be spread between animals and people.

On this year’s World Zoonoses Day, we highlight a new research study published in PLOS Neglected Tropical Diseases (July 2020) that reports on the development, implementation and effectiveness of grassroots mass dog vaccination campaigns against rabies conducted in 2015, 2016 and 2017 in Laikipia County, Kenya.

According to the World Health Organization, rabies kills tens of thousands of people every year, mainly in Asia and Africa. Globally, rabies causes an estimated cost of US$ 8.6 billion per year. Dog bites are responsible for 99% of all cases of human rabies. Therefore, vaccinating dogs is the most cost-effective way to prevent rabies in people.

The research study found that while grassroots volunteer-based dog vaccination campaigns against rabies can be useful, these efforts need to be supported at a larger scale by county and national governments for a more sustainable approach towards eradicating the disease. Below is the author summary.

“Given the importance of mass vaccinations of domestic dogs towards eliminating human rabies in Africa and the site-specific challenges facing such campaigns, additional studies on the development and implementation of such efforts are needed.

One mechanism of mass vaccination lies in grassroots efforts that often begin at a very local scale and either develop into larger campaigns, remain local, or cease to persist past several years once interest and funding is exhausted.

Here, we discuss the development of a grassroots campaign in Laikipia County, Kenya from its local inception to its development into a county-wide rabies elimination effort.

Our results highlight challenges associated with achieving the targeted 70% coverage rate, including a need for consistent and systematic demographic monitoring of dog populations, limitations of the central point method, and logistical and financial challenges facing a volunteer-based effort.

Serious political commitment from both the local and national governments are necessary to take the budget beyond what a crowdfunded campaign can raise, including availability and access to quality dog rabies vaccines.

Without such outside support and substantial time to grow, grassroots campaigns might be better relegated to raising awareness and vaccinating dogs in small communities to protect those communities directly, without contributing to the broader ecosystem-wide transmission-stopping aim often sought by government human health and veterinary organizations.”
