Study identifies risky food safety practices in home kitchens

June 30, 2014, UC Davis

(Medical Xpress)—While most consumers are very aware of food safety issues, including salmonella, and the risk of foodborne illness, many do not follow recommended food safety practices in preparing their own meals at home, according to new research from the University of California, Davis.

The study, which examined preparation of , found that the most common risks stemmed from cross contamination and insufficient cooking.

"The most surprising aspect of these findings to me was the prevalence of undercooking," said Christine Bruhn, director of the Center for Consumer research at UC Davis, who authored the study. "We are now in summer, the peak season for , and these results come at a time when more consumers can benefit from being aware of better practices. Even tips usually considered basic, like washing hands with soap and water before and after handling raw poultry, and never rinsing raw poultry in the sink, still need to be emphasized for a safer experience," added Bruhn, a specialist in UC Cooperative Extension who studies consumer attitudes and behaviors toward food safety.

Most risks can be avoided by practicing thorough hand-washing, never rinsing raw chicken in the sink and using calibrated thermometers to determine that chicken is fully cooked. Researchers say these results will help narrow areas of focus and define important messages for food safety educators and advocates in their mission to promote safe food preparation.

The study analyzed video footage taken of 120 participants preparing a self-selected chicken dish and salad in their home kitchens. The participants were experienced in chicken preparation, with 85 percent serving chicken dishes in their home weekly, and 84 percent reporting being knowledgeable about food safety; 48 percent indicated they had received formal food safety training.

Cross contamination was of specific concern to researchers:
