In low-income urban settings, complementary foods for young children are often stored for several hours under unsafe conditions, increasing the risk of fecal contamination. This randomized controlled trial evaluated whether a low-cost wire-mesh food cabinet (\u201cmeatsafe\u201d), paired with one-time behavior-change communication (BCC), could reduce microbial contamination and diarrhea among children aged 6\u201324 months in the Korail informal settlement of Dhaka, Bangladesh. A total of 290 households were randomly assigned 1:1 to receive a meatsafe plus food-hygiene handouts or no intervention. Over five biweekly post-intervention visits, we collected stored complementary food samples (\u22654 h) for\n                      <jats:italic>Escherichia coli<\/jats:italic>\n                      testing and recorded 7-day caregiver-reported diarrhea. The primary outcome was the prevalence of high-level contamination (\u2265100 CFU\n                      <jats:italic>E. coli<\/jats:italic>\n                      \/g). Prevalence ratios (PRs) were estimated using population-averaged modified Poisson regression adjusted for storage conditions. Across 1,545 food samples, contamination declined in both arms\u2014from 49.6% to 25.2% in controls and 39.0% to 18.6% in the intervention arm\u2014but the intervention had no effect on high-level contamination (adjusted PR\u2009=\u20090.83; 95% CI: 0.55\u20131.26) or caregiver-reported diarrhea (PR\u2009=\u20090.56; 95% CI: 0.24\u20131.31). Storing food for more than eight hours remained strongly associated with contamination (aPR\u2009=\u20091.49; 95% CI: 1.20\u20131.86). Although meatsafe adoption was high (88% at first visit, 99% at last), recall of general hygiene messages was limited. Providing a meatsafe with minimal BCC did not reduce food contamination or child diarrhea, despite excellent uptake. The findings underscore the limits of simple, passive technologies in resource-constrained settings and suggest that future strategies should integrate affordable storage innovations with more intensive and sustained hygiene promotion.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"sec001\">\n                    <jats:title>Trial registration<\/jats:title>\n                    <jats:p>\n                      ClinicalTrials.gov, NCT07332078.
