Intervention
The intervention, targeted to
informal milk vendors in Eldoret,
Kenya, had 3 components:
Training (15 h)
on milk
handling and
safety, and
business skills
Microbiological
testing of milk
and reporting
of lab results to
vendors
Milk marketing
campaign at
vendor shops

Key findings
Lack of observable effect on food safety might be due to…
• Microbiological quality of milk compromised earlier in the supply chain
• Failure to sustain effect overtime
Milk intake in children increased…
… not at the expense of mean probability of micronutrient adequacy
The MoreMilk intervention led to improvements in self-reported practices
and outcomes (process evaluation)
• Increased milk testing for quality
• Stronger negotiation with suppliers
• Better communication with customers around attributes of milk
• Increased sales

Motivation
• Informal vendors are the primary source of milk for most households in Kenya.
• Informally traded milk is often unsafe and prone to adulteration.
• Professionalizing the informal sector holds promise to improve milk safety, but
the effectiveness has not been evaluated.
