North Carolina State University has conducted a study aimed at assessing the impact of washing poultry on kitchen contamination. As a result of the study, researchers found that more than 25% percent of participants contaminated salad with raw poultry, including many participants who didn't wash the poultry. The study showed the importance of hand-washing, as well as cleaning and sanitizing the kitchen, in order to reduce the risk of foodborne illness when cooking at home.
Currently, washing raw poultry isn't recommended, due to concerns about possibly contaminating other foods and surfaces. However, this increases the risk of foodborne illness.
