There is a need to assess the contribution of existing sanitation facilities in the faecal pathogen transmission pathway. This study was conducted as part of a larger planetary health study across 29 rural communities within five river catchments. This specific research aimed to characterise latrine front-ends, both infrastructure and usage behaviour, and to assess the faecal contamination levels on various frequently contacted latrine surfaces in rural Fiji. A sanitation survey, along with observation and latrine swab sampling, was conducted in households over three phases: baseline (<jats:italic>n<\/jats:italic>\u2009=\u2009311) (Aug\u2013Dec 2019), endline (<jats:italic>n<\/jats:italic>\u2009=\u2009262) (Jun\u2013Sep 2022) and an in-depth front-end study (<jats:italic>n<\/jats:italic>\u2009=\u200912) (Oct\u2013Nov 2022). Of 311 households, almost all had pedestal-type latrines, predominately cistern-flush (83%), followed by pour-flush (13%), and then hole-type (pit) latrines (4%). Washable latrine floors had significantly higher <jats:italic>E. coli<\/jats:italic> densities (6.7\u2009\u00d7\u200910<jats:sup>2<\/jats:sup>\u00a0CFU\/25 cm<jats:sup>2<\/jats:sup>) compared to non-washable floors (1.3\u2009\u00d7\u200910<jats:sup>2<\/jats:sup>\u00a0CFU\/25 cm<jats:sup>2<\/jats:sup>) (<jats:italic>p<\/jats:italic>\u2009=\u20090.05), despite washable floors indicating improved latrines. The in-depth front-end analysis found that moist latrine surfaces had significantly elevated <jats:italic>E. coli<\/jats:italic> densities (1.2\u2009\u00d7\u200910<jats:sup>3<\/jats:sup>\u00a0CFU\/25 cm<jats:sup>2<\/jats:sup>) compared to the dry ones (14.3\u00a0CFU\/25 cm<jats:sup>2<\/jats:sup>) (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), highlighting the importance of maintaining dry latrine surfaces. Latrine floors and mid-walls were the most frequently contaminated surfaces, emphasising the need to clean and disinfect these surfaces. Only 46% of the households reported always using soap for handwashing after defecation, exacerbating the risk of transmitting faecal pathogens. This study highlights that latrine cleanliness and hygiene are as crucial as latrine infrastructures for the effective disruption of faecal pathogens transmission during latrine use.<\/jats:p>","DOI":"10.1007\/s11356-024-34668-x","type":"journal-article","created":{"date-parts":[[2024,8,22]],"date-time":"2024-08-22T12:28:00Z","timestamp":1724329680000},"page":"52948-52962","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["An
