A new paper on food safety in low- and middle-income countries was published today (27 Aug 2015). The paper is based on a longer learning resource commissioned by the UK Department for International Development (DFID), which will appear shortly. Both publications reflect what the International Livestock Research Institute (ILRI) and its partners have learned over the last ten years since adopting a framework of risk analysis for assessing, managing and communicating about food safety in developing countries.

Some conclusions
The evidence indicates that low- and middle-income countries bear the brunt of food-borne disease; that developing-country consumers are concerned about food-borne diseases; that most of the known burden of food-borne disease comes from biological hazards; and that most food-borne disease results from eating contaminated perishable foods sold…

Reducing human exposure to aflatoxins in poor countries: Towards new technologies and practices

ILRI news

A new paper describes and assesses the strength of a theory of change for how adoption of farm-level technologies and practices for aflatoxin mitigation can help reduce aflatoxin exposure among consumers.

‘Aflatoxins, naturally occurring fungal toxins that contaminate maize and groundnuts and other crops, pose both acute and chronic risks to human health. Aflatoxins are odourless and colourless and impossible to detect accurately without appropriate testing technologies. Both humans and animals are affected, and there is an additional risk of aflatoxin transmission through animal-source foods, especially milk, from animals fed contaminated feed.

‘Consumption of very high levels of aflatoxins can result in acute illness and death. Chronic exposure, which causes the greater human health burden…

Written by Paula Dominguez-Salas

To improve interventions in food systems of the urban poor, scientists at the International Livestock Research Institute (ILRI) are investigating urban food and nutritional choices in two slums in Nairobi, Kenya. Their aim is to develop interventions that help people make food choices that improve their nutrition while staying within their low household food budgets and access.

Access to healthy diets is at the heart of good nutrition and the achievement of the UN’s Sustainable Development Goals. Foods of animal origin are the only source of vitamin B12 and have good quality protein, preformed vitamin A, highly bioavailable iron, and zinc, in addition to good profiles in other micronutrients. Animal-source foods are…

New journal article presents case studies on CGIAR research on aflatoxins

The CGIAR Consortium, made up of 15 research centres, carries out agricultural research to contribute to the global effort to find solutions to the problems of poverty, hunger, food and nutrition insecurity, and environmental degradation.

Although there is still some disconnection between agriculture, health and nutrition, it is recognized that agriculture does indeed have important effects on human health. Aflatoxins, for example, pose significant health risks in tropical and subtropical regions.

Aflatoxins are highly toxic fungal by-products produced by certain strains of Aspergillus flavus in more than 40 susceptible crops including maize and groundnuts. Aflatoxins cause around 90,000 cases of liver cancer each year and are strongly associated with stunting and immune suppression in children. Aflatoxins in contaminated animal feed not only result in reduced animal productivity, but the toxins can end up in products like milk, meat and eggs, thus presenting a health risk to humans.

A new research paper published in the journal Food Security (20 May 2015) discusses how agricultural research by CGIAR can reduce the health risks from aflatoxin exposure for poor consumers while increasing the opportunities for poor farmers.

The paper, International agricultural research to reduce food risks: case studies on aflatoxins, begins with an overview of the evolution of CGIAR research on food safety and aflatoxins.

It then presents case studies to show how risk-based and market-based approaches as well as crop genetic improvement and biological control can help provide justification for and add value to future CGIAR research on aflatoxins.

In conclusion, the authors present five priority research activities:

1. Generating evidence on the human and animal health impacts of aflatoxins
2. Understanding the potential of improved technologies and good agricultural practices to reduce aflatoxin exposure in farm households and communities
3. Assessing the costs and benefits of proposed strategies on aflatoxin reduction as well as other goals such as income and food security
4. Assessing how costs and benefits are distributed across men and women in households and across different types of households in communities
5. Understanding factors that facilitate and constrain adoption of aflatoxin control strategies would also be assessed, with particular emphasis on gender issues, incentives and on the role of health information and communication.

The paper was written by scientists from the following CGIAR centres: the International Livestock Research Institute (ILRI), the International Institute of Tropical Agriculture (IITA), the International Food Policy Research Institute (IFPRI) and the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT).

New ILRI report reviews the knowns and unknowns of antimicrobial resistance in animal agriculture in developing countries

Antimicrobial resistance occurs when microorganisms (bacteria, viruses, fungi and parasites) develop the ability to continue growing in the presence of an antibacterial, antiviral, antifungal or antiparasitic substance to which they were previously sensitive.

The use of antibiotic drugs to prevent and treat livestock diseases is a key driver for the development of agriculture-related antimicrobial resistance which is now a global public health problem as antibiotics in food animals can enter the food chain and affect the health of consumers and communities.

In developing countries, antimicrobial resistant pathogens are commonly found in animals, animal food products and agro-food environments. However, the lack of national surveillance systems means that we do not have reliable estimates of the true burden of antimicrobial resistant infections in developing countries.

In addition to lack of accurate information on antibiotic use in developing countries, there is limited understanding of the sources of antimicrobial resistance in animal agriculture and the relative importance of different sources.

In order to address these concerns, the International Livestock Research Institute (ILRI) has this month (June 2015) produced a report which aims to identify key evidence gaps in our knowledge of livestock- and fisheries-linked antimicrobial resistance in the developing world, and to document ongoing or planned research initiatives on this topic by key stakeholders.

ILRI veterinary epidemiologist Delia Grace wrote the report which reviews the knowns and unknowns of

• the prevalence of antimicrobial resistant infections in livestock and fish systems and products;
• the health and economic impacts of livestock- and fisheries-linked antimicrobial resistance in the developing world;
• technical capacity in developing countries to assess antibiotic use and antibiotic resistance in the livestock and fisheries sub-sectors;
• key drivers of antimicrobial resistance in livestock and fisheries production in the developing world; and
• modalities of reducing antibiotic use and levels of resistance.

She concludes with a call to address the global problem of antimicrobial resistance through an evidence-based approach which includes filling knowledge gaps, careful piloting of interventions and rigorous evaluation of success and failure.

The report was produced by ILRI for Evidence on Demand with the assistance of the UK Department for International Development contracted through the Climate, Environment, Infrastructure and Livelihoods Professional Evidence and Applied Knowledge Services programme, jointly managed by DAI (which incorporates HTSPE Limited) and IMC Worldwide Limited.

A4NH 2014 annual report highlights ILRI book on food safety research

The CGIAR Research Program on Agriculture for Nutrition and Health (A4NH) led by the International Food Policy Research Institute (IFPRI) last week (4 June) published its 2014 annual report, marking three full years of its first phase of research.

The report highlights a range of research work by the program’s flagships, including the delivery of biofortified crops, work on aflatoxin control and the development of a new global indicator to measure women’s dietary diversity.

The International Livestock Research Institute (ILRI) leads the A4NH flagship on agriculture-associated diseases. The annual report features a key output of this flagship, namely, a new book, Food Safety and Informal Markets: Animal Products in Sub-Saharan Africa, published in October 2014.

Edited by ILRI researchers Kristina Roesel and Delia Grace, the book synthesizes lessons from 10 years of food safety research in Africa, including 25 case studies from countries in East, West and Southern Africa, as part of the Safe Food, Fair Food project.

 

Global conference on One Health features ILRI research on antimicrobial use in developing countries

Livestock production is beset by many challenges. Animal diseases, in particular, can lead to reduced production of milk, meat and eggs. In some cases, animal disease infections may result in death, leading to loss of livelihoods for livestock keepers.

Livestock in developing countries suffer a high burden of preventable disease, and this burden is likely to increase as livestock systems become more intensive. Antibiotics and other antimicrobial drugs are often used to treat animal disease infections.

However, authors of a study published in March 2015 in the Proceedings of the National Academy of Sciences of the United States of America (PNAS) warn that the use of antimicrobial drugs in livestock production could contribute to the spread of drug-resistant pathogens in both livestock and humans, posing a significant public health threat.

The study also projects that by the year 2030, global antimicrobial consumption will rise by 67% and nearly double in Brazil, China, India, Russia and South Africa.

In light of the global nature of the problem of antimicrobial resistance, the World Veterinary Association and the World Medical Association prioritized the topic during one of the sessions at their global conference on One Health held in Madrid, Spain on 21-22 May 2015. The conference was organized in collaboration with the Spanish medical and veterinary associations.

Over 300 delegates from 40 countries attended the conference which was aimed at achieving stronger collaboration between physicians, veterinarians and all relevant stakeholders to improve various aspects of the health and welfare of people, animals and the environment.

Delia Grace, veterinary epidemiologist and leader of the Food Safety and Zoonoses program of the International Livestock Research Institute (ILRI), attended the conference and presented on antimicrobial use in developing countries, highlighting some results from research by ILRI.
