Abstract
Abstract Objectives A multi-year, integrated methods study showed comprehensive consumer food handling practices when preparing a meal, compared to prevalence of self-reported behaviors. Experimental conditions provided insights on the effectiveness of current and future food safety messages. Methods Demographically-diverse participants were recruited from various communities in one state. Year 1: Participants prepared raw turkey burgers in a simulated home kitchen. Half of participants viewed an educational video on thermometer use before meal preparation; the other half served as a control. Year 2: Participants who self-reported washing poultry prepared raw chicken products. Half of participants received mock social media messages about not washing poultry; the other half served as a control. Food handling behaviors were coded and compared to self-reported actions and attitudes towards food safety, collected via written surveys and in-depth interviews. Results At least one contributing factor to foodborne illness was examined during each observation; cross-contamination actions were always observed. Year 1: Over 60% (n = 383) of participants self-reported owning and using a food thermometer when cooking raw meat and poultry products; however, only 35% of unprompted participants measured final internal temperature with a food thermometer. Year 2: Nearly 25% (n = 300) of participants cross-contaminated a ready-to-eat side; over 50% cross-contaminated due to poor sink sanitation. Differences between self-reported and observed food safety behaviors were seen across participant groups. Lack of sufficient handwashing leading to bacterial cross-contamination was a notable secondary outcome. Conclusions Observations more accurately reflect consumer food handling behaviors and allow for targeted message development to decrease risk of foodborne illness through safe at-home food handling. Findings and messages are shared with health educators, news and social media outlets, and directly to consumers through various resources.
