Milk Product Safety and Household Food Hygiene Influence Bacterial Contamination of Infant Food in Peri-Urban Kenya
BACKGROUND: Milk is a common infant food in peri-urban Kenya that can transmit diarrhea-causing enteric pathogens. Little is known about how contamination of milk at point of purchase and household handling of milk-based infant foods contribute to infant exposure to enteric pathogens. OBJECTIVE: To compare the prevalence and concentrations of bacterial indicator organisms and enteric pathogens in unpackaged, fresh pasteurized, and ultra-high temp…
Marketing fortified rice
Fortification of staple foods is among the most cost-effective public health interventions. In settings where mandatory fortification is not feasible, providing fortified foods through public safety net programs and building private demand can be implemented in parallel to maximize coverage. However, little is known about what marketing messages are most effective at increasing the demand for fortified foods. Further, as governments scale up fort…
Improving food safety on the farm
Evidence is emerging that foodborne illness accounts for a staggering health burden in developing countries. However, standard approaches used by developed country governments to ensure food safety are not appropriate in settings where regulatory enforcement capacity is weak and most firms are small and informal. Using a randomized field experiment, we test the impacts of subsidies and a price premium for safer produce on farmer adoption of techn…
Information, technology, and market rewards
The quality of agricultural products can affect both farm incomes and the healthfulness of farm families’ diets. However, many quality attributes are hard to observe, making it difficult for farmers to learn how to improve the quality of their crops. Lack of premium pass-through and the cost of quality-enhancing inputs are additional barriers to improving output quality. In this paper, we examine the relative importance of each of these barriers …
Observability of food safety losses in maize
Relief from usury
Provision of low-cost credit to the poor through self-help groups (SHGs) has been embraced as a key poverty-reduction strategy in developing countries, but evidence on the impact of this approach is thin. Using a randomized program rollout over 180 panchayats, we evaluate the impact of a government-led SHG initiative in the Indian state of Bihar. Two years after the start of the program, we find a dramatic increase in SHG membership, borrowing fr…

Measuring and Mitigating HIV Stigma
Stigma against those living with HIV can undermine efforts to prevent the spread of the disease, but it has traditionally been hard to measure or to assess the efficacy of antistigma educational efforts. Using a framed field experiment involving adult participants in rural Kenya, this research measures HIV stigma as the amount of compensation demanded through a second-price auction to complete tasks involving objects handled by an HIV-positive pe…
