Background: Previous research has suggested many households are meeting the Federal Emergency Management Agency’s 3-day emergency food and water storage recommendations. The impact of limited economic household resources on emergency preparedness practices related to food and water is uncertain. The purpose of this study was to compare emergency preparedness practices in households participating in United States’ food assistance programs with households not participating in these programs. Methods: A convenience sample of adults (n = 572) completed an online Qualtrics survey. Descriptive statistics, chi-square statistics, and independent t-tests were used to measure differences between households participating in food assistance programs vs. non-participating households. Results: Most households participating in food assistance programs felt prepared to provide household members with food and water during an emergency, which did not significantly differ from non-participating households. Households using food assistance programs had less accessible cash but had similar foods on-hand for an emergency compared to non-participating households. However, they more frequently reported having baby formula/food and less frequently reported having vitamin/mineral supplements compared to non-participating households. Conclusions: Food assistance programs may be effective in providing enough food and water to help low-income families be prepared for an emergency.
