A Mixed Methods Approach to Investigating Food Safety Behavior in a Sample of Native American and Hispanic Caregivers of Young Children

Abstract

Foodborne illness (FBI) disproportionately affects children and minority populations in the U.S. A mixed methods convergence model design was used to explore the food safety knowledge and behavior of Native American (NA) and Hispanic (Hisp) caregivers in New Mexico who prepare food for young children in the home. Quantitative and qualitative research methods (a validated food safety knowledge survey (r=.793) and focus group interviews) were implemented in parallel within each ethnic group, the datasets were analyzed separately per group and the results were converged at the point of interpretation. Equal priority was given to each dataset type. The Health Belief Model was used as a theoretical framework to guide qualitative inquiry. An integrative summary of the quantitative and qualitative results was created and meta-inferences identified contradictory and confirmatory elements of the evidence across both groups. A purposeful sample of fifty-five participants in New Mexico (28 NA; 27 Hisp) completed the food safety knowledge survey and participated in focus groups. Quantitative composite mean scores for the Native American (NA) group (M=66%) and Hispanic (His) group (M=65%) indicated low food safety knowledge. A MANOVA conducted to compare the two groups' mean knowledge scores found no significant difference between groups on the food safety subscales [Wilks' Λ = .852, F(6,44) = 1.278, p = .287, η2 = .162].The lowest scoring subscale for both groups was 'cook', addressing proper cooking methods (NA=.61, Hisp=.55). Mixed methods analyses revealed that participants overall perceived moderate to high self-efficacy regarding safe food preparation, food purchasing, cooking food, and storing of food, however, the related food safety knowledge item scores were low. Food safety knowledge was often inconsistent with reported food safety practices. Moderate/high self-efficacy may provide a false sense of low risk for FBI.

Insight into food handlers’ perceived barriers and motivators to perform food temperature control practices in Malaysian public schools

“…The lack of knowledge on the use of food thermometer could be due to the limited scope covered in the training and lack of hands-on training on the use of thermometer. Other studies have also reported that inadequacy of knowledge is an important barrier (Santos et al, 2008;Siebert et al, 2014;Siau, 2015). Food handlers exhibit lack of knowledge on temperature control especially related to the recommended endpoint temperature, the method to use the thermometer and thermometer use for specific food groups (Strohbehn et al, 2014;Arendt et al, 2015).…”

Investigating child care food safety culture and barriers & motivators to safe food handling practices

“…A mixed methods approach was used to explore food safety knowledge, beliefs, and practices of Native American and Hispanic food handlers (n= 55) caring for young children (Siebert et al, 2014 . Barriers to increased food safety practices were shown as lack of resources (42% of the directors reported either losing money or just breaking even) and lack of knowledge (directors consistently reported child care employees did not know how long to properly wash hands, with answers ranging from 10 to 180 seconds) .…”
