Handwashing in 51 Countries: Analysis of Proxy Measures of Handwashing Behavior in Multiple Indicator Cluster Surveys and Demographic and Health Surveys, 2010–2013. Am Jnl Trop Med & Hygiene, June 12, 2017.

The objective of this analysis is to describe global handwashing patterns using two proxy indicators for handwashing behavior from 51 DHS and MICS surveys conducted in 2010–2013: availability of soap anywhere in the dwelling and access to a handwashing place with soap and water. We found large disparities for both indicators across regions, and even among countries within the same World Health Organization region.

Food safety in developing countries: research gaps and opportunities. Feed the Future, 2017.
There are four major lines of defense against FBD: Improving the safety of inputs; Improving the chemical and microbiological safety of raw foodstuffs; Using food processing technologies that mitigate risk (pasteurization and irradiation) and prevent contamination; Behaviour change aimed at food handlers, including home-based food handlers.

However, the balance of evidence suggests that there should be concerns especially when considering the evidence from jewellery workers.

Water/sanitation/hygiene professionals have attempted, with only limited success, to reduce fecal exposure and human disease in the absence of definitive civil engineering approaches.
