Dairy feed project to reduce aflatoxin contamination in Kenya’s milk

Global Agenda Visit to Ol Kalou: Milk Cans

Mycotoxins, such as aflatoxin, are toxins found in food that can cause illness and be lethal in high doses. These toxins are formed by strains of moulds that infest susceptible grains such as maize and sorghum. Dairy cows that eat contaminated feed can yield contaminated milk.

Milk is a major food in Kenya. Understanding how, and to what extent, these toxins affect dairy products in this country is under investigation by scientists at the International Livestock Research Institute (ILRI).

‘We don’t know enough about the specifics of milk consumption in Kenya’, says Johanna Lindahl, a food safety researcher at ILRI. ‘We know that some groups, such as young children, pregnant and nursing women, as well as livestock herders, consume more milk than others.’

ILRI is determining the risks posed to such different groups of people by exposure to aflatoxin-contaminated milk in a ‘My-Dairy’ project in Kenya funded by Finland’s Ministry of Foreign Affairs. In a series of studies, this project, which is under the CGIAR Research Programs on Agriculture for Nutrition and Health (A4NH) and Policies, Institutions and Markets, is also assessing the economic impacts of contaminated dairy feeds and the most appropriate ways of reducing aflatoxins along Kenya’s dairy feed chain.

‘Because people in Kenya consume much more milk than people in other African countries, with estimates as high as 145 litres per person each year, Kenyans are likely to be more at risk from aflatoxin-contaminated milk than other Africans’, Lindahl says.

‘We’ve been carrying out a series of “participatory rural appraisals” in villages to understand the current knowledge, attitudes and practices of farmers’, she says.

Preliminary findings from this research were presented at an ILRI lunch roundtable for science journalists in Nairobi in Nov 2013. The briefing highlighted on-going multi-institutional efforts to combat aflatoxins in the food and feed chains of Kenya.

Read a series of 19 briefs released Nov 2013 by the International Food Policy Research Institute (IFPRI) and its 2020 Vision initiative jointly with the CGIAR Research Program on Agriculture for Health and Nutrition (A4NH), which is led by IFPRI, with a component on Agriculture-Associated Diseases led by Delia Grace, of ILRI. Grace co-edited the series of briefs, co-authored the overview (Tackling Aflatoxins) and wrote the brief on Animals and Aflatoxins. Two other ILRI scientists, Jagger Harvey and Benoit Gnonlonfin, of the Biosciences eastern and central Africa-ILRI Hub, in Nairobi, Kenya, are among the authors of the brief on Improving Diagnostics for Aflatoxin Detection.
