Training of milk vendors in Kenya’s informal dairy sector could be a pathway to progressively bring the informal sector under the food safety regulatory systems, says a new study by scientists from the International Livestock Research Institute and the International Institute for Development and Environment.

The informal dairy sector in Kenya contributes to nutrition security, health and livelihoods. However, concerns over milk safety have seen the sector de-legitimized. Training and capacity-building of those operating in the sector has the potential to deliver on multiple development outcomes, over and above improved food safety.

The study, which is published in Global Food Security (September 2018), examined the incentives and challenges to operating in the informal dairy sector in two urban areas in Kenya (Eldoret and Kisumu) and the perceived benefits and socio-economics effects of training. A survey of informal dairy vendors and testing of milk was also carried out in the two regions to assess milk safety and handling practices and their relation to training.

It was noted that the informal dairy sector in Kenya is an important source of livelihood opportunities, especially for women. Training of milk vendors improved sales, reduced milk losses and helped expand the businesses of vendors; however, the long-term effects of training on milk quality are not evident. Accessibility and clear incentives to participate in training could maximize impact and sustainability.

Based on this qualitative assessment, it is recommended that rigorous scientific studies be conducted to confirm and measure the magnitude of those impacts on health, nutrition and societal outcomes derived from training and capacity building activities in the informal dairy sector.

Representatives from the dairy sector in Kenya met at the Nairobi campus of the International Livestock Research Institute (ILRI) in March 2018 for a one-day meeting organized to present the research findings and plans of two dairy projects that ILRI is undertaking in collaboration with other partners: Measuring and mitigating the risk of mycotoxins in maize and dairy products for poor consumers in Kenya (MyDairy) and MoreMilk: making the most of milk (MoreMilk).

The meeting, dubbed Growing with Dairy, brought together 33 participants representing different stakeholder groups in Kenya’s dairy sector including industry, government, consumers, academia and development organizations.

Presentations by the principal investigators of the MyDairy and MoreMilk projects discussed various activities and interventions aimed at improving the dairy sector in Kenya and boosting the health and economic benefits that Kenyans derive from the sector.

The meeting also provided an opportunity to disseminate research findings, receive feedback on ongoing and planned activities, and align project objectives with the needs of public and private actors in the dairy sector in Kenya.

The MyDairy project was funded by the Ministry of Foreign Affairs, Finland and implemented between 2012 and 2018 in two phases: an initial four-year phase followed by a second phase of 1.5 years. The project aimed at mitigating the risks of aflatoxins in the dairy value chain in Kenya.

The MoreMilk project is a five-year initiative (2016–2021) funded by the Bill & Melinda Gates Foundation and the United Kingdom government that works to upgrade milk hygiene and quality standards in the informal dairy value chain and maximize economic, health and nutrition benefits, especially for the poorest communities in Nairobi.

A new research paper by scientists at the International Livestock Research Institute (ILRI) and partner organizations confirms that milk, meat and eggs are widely consumed by poor people in Kenya’s capital city of Nairobi: these animal-source goods make up nearly 40% of the food budget and half of this is spent on dairy products.

Economic analysis revealed a high propensity to consume animal-source foods and elasticities showed that, if their prices could be lowered, consumption of animal-source foods would rocket, benefiting both the nutritional status of poor consumers and the livelihoods of small-scale livestock producers.

Abstract
‘Malnutrition, including undernutrition and micronutrient deficiencies, is a chronic problem in most developing countries. Animal-source foods (ASFs) provide essential sources of proteins and micronutrients, yet little is known about ASF consumption patterns or household preferences towards animal-source products among low-income populations. This is particularly critical for malnourished children…

Testing milk in Kenya's informal market

Testing the quality of raw milk in Kenya’s informal market. A new study has identified options that could help improve milk quality in Zambia’s Western Province (photo credit: ILRI/Dave Elsworth).

Solar pasteurisation and quality-based pricing of milk are among interventions whose feasibility should be explored towards improving the safety of milk produced by smallholders in Western Province of Zambia, a new study says.

The study published in the International Journal of Environmental Research and Public Health (July 2016) was carried out to assess the microbiological quality of fresh cow’s milk along smallholder dairy value chains in Western Province of Zambia. The focus was on milk sold through dairy co-operatives near Mongu, the main town in the province.

Milk samples were collected at the farm level from 86 cows from nine herds and from the container of pooled milk from the herd. Samples were also collected upon arrival at the two dairy co-operatives (Limulunga and Mongu) to which the pooled milk was delivered. Additional serial samples were collected at the co-operatives and refrigerated to simulate the recommended storage conditions after purchase or at the co-operatives.

Microbiological analysis of the milk samples assessed the counts of total bacteria and coliforms and tested for the presence of Staphylococcus aureus, Escherichia coli, Bacillus species and Streptococcus species.

The milk at the farm level initially had low levels of bacteria but the microbial counts increased along the value chain as the milk was transported to the co-operative. This is in part due to the absence of a cold chain between milking and the point of sale.

Although coliform counts were low, a high proportion of samples were contaminated with S. aureus and E. coli, suggesting poor handling and faecal contamination, respectively. However, the most critical observation with regard to milk safety was the lack of pasteurisation or boiling, which would eliminate almost all microbial pathogens present.

The study therefore proposes that more work should be done to look into the feasibility of various interventions that could improve the quality of milk produced and sold in the region.

“Sustainable methods of milk pasteurisation should be investigated, as a microbial-kill step is needed to mitigate upstream contamination,” the authors observe.

Solar pasteurisation has been suggested as a possible option to be explored, in light of unreliable electricity supply, low levels of technical support and low volumes of milk handled at the dairy co-operatives.

“Paying producers more for safer, higher quality milk would create an incentive for producer investment in milk quality,” they add. Currently, all farmers receive the same price for their milk, regardless of the quality.

Selling milk to large dairies is not feasible at the moment because the quantities of milk produced are low and inconsistent. Also, most consumers prefer to buy milk from the informal sector.

Therefore, raising awareness of the need to boil milk before consumption is another important intervention that would improve milk safety at the consumer stage of the value chain by eliminating the pathogen risk. In addition, it may increase consumers’ willingness to pay for pasteurised milk.

Interventions to improve food safety and nutrition may be some of the best investments for improved health of populations. Ideally, these investments should target multiple disciplines to link health and education to agricultural systems.

Fermentation of dairy products is one such intervention that helps to extend their shelf life and improve microbial safety and nutritive quality. Sylvain Traoré, a postdoctoral scientist at Centre Suisse de Recherches Scientifiques in Côte d’Ivoire, has been continuing with research he started through the Safe Food, Fair Food project on the use of participatory methods to improve the safety of dairy products in informal markets.

Traoré recently carried out a cross-sectional study in Korhogo, northern Côte d’Ivoire to assess local dairy fermentation technologies and map the local dairy supply chain to identify areas where interventions can be…

Typical milk bar in Kenya

Kenya’s informal dairy markets are central to the livelihoods, food security and nutrition of the majority of its citizens, particularly the poor, women and children. Kenya’s informal dairy market is significant in size – 86% of Kenya’s milk is sold by unorganized, small-scale businesses in informal markets or consumed directly at home. The sector generates 70% of the 40,000 jobs in dairy marketing and processing.

The International Institute for Environment and Development (IIED) has been working in partnership with the International Livestock Research Institute (ILRI) in Kenya to explore the impacts of efforts to govern Kenya’s dairy sector in a way that works with, rather than against, informal, small-scale milk vendors. We looked at the impact on milk vendors, on food safety and on sustainability, with the findings published in the final briefing in a series on innovations in policy approaches to informality.
