摘要：This article describes food safety educational tools depicting safe handling of leafy greens that are available as downloadable posters to Extension educators and practitioners ( www.extension.iastate.edu ). Nine visual-based minimal-text colored posters in English, Chinese, and Spanish were developed for use when formally or informally educating foodservice workers about safely handling leafy greens. A three-phase methodology included the use of expert knowledge, microbial sampling, and observational study in Iowa and Kansas foodservice operations. Use of the posters was shown to have positive impacts on both microbial levels and food safety behaviors, suggesting that the posters can be useful tools for Extension personnel.
