From 26 May 2021 to 8 June 2021, PubMed, Scopus, Web of Science and CAB abstracts were searched for peer-reviewed literature. In addition, reference lists of identified papers were hand-searched to identify additional papers. The search strategy was drafted by the first author and refined through team discussion. The search terms included keywords related to drinking water, sanitation, handwashing and hygiene facilities in food markets, their use by vendors, national and local regulations that apply to such settings and evidence from interventions (Table 1). The search results were then filtered by country of author affiliation in each data base, to limit results to countries in North and sub-Saharan Africa. These were exported into EndNote X9 (Clarivate, Philadelphia, PA). After removing duplicates, the title, abstract and full-text were screened by the first author.
