A Kansas State University study has shown that when preparing frozen foods, adolescents are less likely than adults to wash their hands and are more susceptible to cross-contaminating raw foods while cooking.
"While half of the adults we observed washed their hands after touching raw chicken, none of the adolescents did," said Casey Jacob, a food safety research assistant at K-State. "The non-existent hand washing rate, combined with certain age-specific behaviors like hair flipping and scratching in a variety of areas, could lead directly to instances of cross-contamination compared to the adults."
Food safety isn't simple, and instructions for safe handling of frozen chicken entrees or strips are rarely followed by consumers despite their best intentions, said Doug Powell, K-State associate professor of food safety who led the study.
As the number and type of convenience meal solutions increases - check out the frozen food section of a local supermarket - the researchers found a need to understand how both adults and adolescents are preparing these products and what can be done to enhance the safety of frozen foods.
In 2007, K-State researchers developed a novel video capture system to observe the food preparation practices of 41 consumers - 21 primary meal preparers and 20 adolescents - in a mock domestic kitchen using frozen, uncooked, commercially available breaded chicken products. The researchers wanted to determine actual food handling behavior of these two groups in relation to safe food handling practices and instructions provided on product labels. Self-report surveys were used to determine whether differences exist between consumers' reported food handling practices and observed behavior.
