摘要

Mold contamination poses persistent challenges in disaster relief shelters, where moisture, limited ventilation, and dense occupancy create conditions favorable for rapid fungal growth. Traditional prevention measures, such as chemical treatments and mechanical drying, often face logistical and resource limitations. Microbiome engineering has been proposed as a novel intervention, yet little is known about public perceptions of such an approach. This study presents the first empirical analysis of attitudes toward introduced microbiomes (IM) in the context of emergency housing. Using a nationally representative survey of 1,000 U.S. adults, we examined demographic, informational, emotional, and risk-related predictors of support across three dimensions: willingness to adopt IM in shelters, support for rigorous evaluation and testing, and support for survivor education. Hierarchical regression models explained 55.7% of variance in adoption, 27.4% in testing, and 21.4% in education support. Findings reveal that adoption support was driven by efficacy beliefs, trust, and affective responses; testing support was shaped by demographic factors and secondary risk concerns; and education support reflected demographic variation and threat appraisals. Across all models, interest in learning more about microbiome engineering consistently predicted higher support, while prior information-seeking often predicted greater caution. These results underscore the importance of integrating public perspectives alongside technical assessments when evaluating microbiome engineering for disaster relief.
