Indigenous markets for dairy products in Africa: trade-offs between food safety and economics

In the absence of information on which to base policies in emerging dairy markets in developing countries, public officials have tended to rely on models for dairy product marketing and health assurance derived from industrialised countries where large-scale production systems, cold-chain pathways and milk pasteurization and packaging are key features. These models have invariably failed in many African market situations where small-scale dairy systems without cold-chain market pathways currently dominate and will continue to do so in the foreseeable future. The main reason is simple: many resource-poor consumers simply refuse to pay the extra costs that pasteurized, packaged milk incurs, and prefer to buy raw milk and boil it themselves. But the role of traditional preferences should not be discounted: in Kenya, high-income consumers express the same preference for raw milk as do those with lower income, and often end up buying more of it. As a result, informal or raw milk and traditional product markets generally dominate in developing countries, comprising over 90% of the market in Tanzania and Uganda, for example, and some 83% of the market of the world’s largest milk producer, India. In Kenya, the informal market has some 85% market share. The issue, of course, is public health concerns linked to raw milk. Current dairy market policies throughout the developing world have largely been adopted from the West, and reflect international standards of food safety, etc. However, as the percentages above show, they are being systematically ignored, and as a result, most consumers buy milk and dairy products that are completely outside any regulatory environment. It is possible that to better address the public health issues, policies may need to take a more pro-active approach to informal milk trading, and which better address the realities of consumer willingness to pay for higher standards. The policy question which needs to be answered is thus: is it preferable to maintain strict milk standards which result in higher costs and thereby free most marketed milk into informal channels, or is the public better off by standards that are relaxed but capture more of the informal market? If standards were relaxed to allow raw milk marketing, yet maintain some regulations regarding handling and if some incentives were given to milk traders to comply (e.g., training and certification), then a much larger proportion of the milk market may fall under regulatory control, improving the average standards of milk in the market. An important step to addressing this issue is to collect quantitative and qualitative information about milk-borne health risks under different production and marketing situations. This paper describes specific dairy marketing studies in Kenya, Ghana and Tanzania aimed at assessing public health risks from informally marketed milk and examines the economic trade-offs that policy makers should consider. Preliminary results from Kenya are presented and recommendations on cost-effective and practical interventions to improve milk safety made

Market mechanisms and efficiency in urban dairy products markets in Ghana and Tanzania

This research report presents an analysis of the problems encountered in the milk markets in Ghana and Tanzania. It is based on a study carried out during 1999 and 2000 to identify and quantify the public health risks and economic performance in dairy product markets in these two countries. The study was led by the International Livestock Research Institute (ILRI). Scientists from the University and Technology (Kumasi, Ghana), the Animal Research Institute (Accra, Ghana), Sokoine University of Agriculture (Morogoro, Tanzania) and the Natural Resources Institute (UK) collaborated in implementing the study. Funding was obtained from the UK Department for International Development-Livestock Production Programme (DFID-LPP). This report is divided into an executive summary and a main section. The summary highlights the methodology used and the main outcomes of the research. Chapter 2 addresses market mechanisms and efficiency and contains the results of the economic and structural analysis. The key findings and achievements of the study. The main report gives a detailed account of the markets. Chapter 3 deals with the milk-borne public health risks, and focuses on the results of laboratory testing of milk and dairy product samples; this chapter also uses some of the economic results in the analysis. Processing of traditional dairy products is the topic addressed in Chapter 4, with a focus on the traditional fresh cheese, wagashi, in Ghana. Chapter 5 presents the impacts of the training activities conducted during the study while Chapter 6 indicates ways in which the project contributed to meeting the research goal. The project team hopes that the technologies and strategies developed in this study will inform development in other similar production and market systems

Risk of exposure to marketed milk with antimicrobial drug residues in Ghana

The study was carried out to determine the extent to which antimicrobial drugs may be translocated into milk and the associated risk of exposure by consumers. A total of 394 milk samples were collected in the study sites in dry and wet seasons, and from different categories of milk market agents, including producers (farmers), processors, wholesalers (assemblers) and retailers. The milk samples were screened for antimicrobial drug residues using the Charm Aim-96 antimicrobial inhibition assay screening kit. Overall, 35.5% (140/394) of the milk samples collected were contaminated with one or more of the antimicrobial drugs screened. This translates into an average risk of exposure every third time a consumer drinks locally produced milk. There was no significant difference in contamination levels between season and area of sampling. Among market agents, contamination levels ranged from 16.6% (9/54) for wholesalers or milk assemblers to 54.2% (13/24) for milk processors. There were no significant differences in prevalence proportions of drug residues in milk from different types of traders between and within locations

Risk factors in the hygienic quality of milk in Ghana

The study was carried out to identify risk factors associated with bacterial contamination of locally produced raw milk and its adulteration with water. A total of 419 respondents of different categories of milk agents in the study sites were sampled for data and milk collection in the dry and wet seasons. The data collected focused on milk marketing factors and handling practices likely to affect milk quality, while the milk samples were analysed to determine the extent of bacterial contamination and adulteration with water. The proportion of milk samples adulterated was 18%. While 23.5% of the milk samples had unacceptably high total plate count ( > 6.3 log10 cfu/ml), all the samples had unacceptably high coliform plate count ( > 0.7 log10 cfu/ml). Risk factors associated with high bacterial counts were related to milk marketing channels (p < 0.05), milk market agents (p < 0.01), and milk containers (p=0.06) as well as their mode of cleaning (p=0.06). The only risk factor identified for adulteration of milk was related to season (p=0.04)
