Non Technical Summary
The goal of this project is to develop, evaluate and deliver educational materials and training programs to enhance retail grocery store food safety. Continued efforts are needed to provide food safety education to the retail food and foodservice industries, including grocery stores. Retail grocery industries may not allocate sufficient time, money or personnel toward food safety training for their employees. Additionally, high employee turnover and increasing numbers of workers who do not read English well are important barriers to effective training. This project will focus on grocery stores or supermarkets since they not only have these concerns, but also are increasingly conducting more in-store food preparations, such as slicing, cooking, packaging, and cold-holding. The target audience of this proposal includes grocery store employees (deli, meat and poultry, seafood, and produce departments), State government retail food inspectors, and Extension Agents. Proposal objectives include: a) develop and implement a food safety educational needs assessment (demographics, existing food safety knowledge, literacy level, preferred educational delivery methods, and applicability of current educational materials) for grocery employees in Virginia and Pennsylvania; b) develop and evaluate food safety educational programs for grocery store workers and managers; c) develop and evaluate graphical and bilingual (English and Spanish) food safety messages (reminders, warnings, instructions) for the grocery industry; d) disseminate educational materials to grocery stores and others, and assess their effectiveness; e) assess the knowledge gain and changes in food safety behaviors and attitudes for the target audiences.

Goals / Objectives
We plan to develop and evaluate educational materials and training programs for enhancing retail grocery store food safety. This project will focus on grocery stores or supermarkets since they not only have all the concerns described previously, but they are also increasingly conducting more in-store food preparations, such as cutting and slicing, (re-)packaging, and cold-holding. We plan to develop and evaluate a curriculum that will provide researchers with information on knowledge gained, self-reported and observed practices, changes in attitudes and behaviors, both immediately after training and several months later. The educational delivery methods to be employed include, but are not limited to: computer mediated training; face-to-face training; videos; or written materials. The success of the educational components of this project may lead to future opportunities for Extension and outreach educators to deliver specific food safety messages to food handlers. Specific objectives and deliverables are: 1. Convene a project steering committee consisting of food safety professionals to provide logistical support to the project. 2. Develop and implement an educational needs assessment for grocery employees in Virginia and Pennsylvania to determine demographics, existing food safety knowledge, literacy level, preferred educational delivery methods, and applicability of current educational materials. 3. Develop educational tools (e.g. CD-ROM, video, face-to-face trainings, or printed materials) to educate grocery store workers and managers on food safety that can be incorporated into existing store training activities. 4. Develop and evaluate graphical food safety messages. 5. Disseminate the educational materials to employees and managers of the participating grocery stores, and assess the effectiveness of the materials. 6. Improve and refine the educational materials for a larger distribution to the target audiences. 7. Assess the knowledge gain and attitude/behavior changes for the target audiences.
Project Methods
The target audience of this project includes State government retail food inspectors, Extension Agents, and grocery store employees (Deli, Meat and Poultry, Seafood, and Produce Departments). Our aim is to improve food handling practices and behavior using focused training at the food retail level. This will be accomplished primarily by evaluating current food safety educational materials and training programs, developing and evaluating a defined learning tool set for grocery store retail outlets with an emphasis on graphical food safety messages, and distribution of the educational materials with an assessment of knowledge gain and attitude/behavior changes that promote safe food handling. Evaluation of the educational efforts and evaluation instruments of this project will be conducted by several methods. Evaluation criteria will include 1) accuracy and comprehension of subject matter presentations; 2) determination of the effectiveness of food safety training efforts (e.g. knowledge pre- and post-tests or interviews, and observation or video surveillance); 3) evaluation of project processes (e.g. communication, timeliness, enhanced collaboration, outreach material development and distribution). Other outreach efforts will be focused on integration of research findings on effective educational tools, with evaluations of effective distribution and use of these tools and the effectiveness of training sessions to enhance food safety practices. Outreach or Extension communications efforts can be disseminated through a Cooperative Extension publication and/or website. Project results and conclusions will also be disseminated through presentations at national conferences of pertinent professional organizations and food retail industry meetings or conferences. Significant findings in the areas of applied food safety research and food safety education and training will be submitted to a peer-reviewed journal for publication. Dr. Eifert (Virginia Polytechnic Institute and State University) will be the lead Project Director (PD). Dr. Cutter will serve as the lead Project Director at Pennsylvania State University (collaborating institution). The Project Directors and co-PDs will work together to develop, evaluate, refine, and disseminate the needs assessment and educational intervention(s) and evaluate and disseminate the educational components in each state.

Impacts
What was accomplished under these goals? Part A:In 2009, we convened a project Steering Committee consisting of food safety professionals who work in or with the retail grocery industry, to provide logistical support to the project. Committee discussions focused on current educational programs being conducted at grocery/retail outlets, educational gaps associated with current food safety programming, and assessment of their food safety educational needs. The Steering Committee discussions were used to focus our educational efforts for grocery stores and small food retailers (e.g. <30 employees, <5 establishments) that may benefit from food safety education for employees who may not read English well or who primarily speak Spanish. Part B:A food safety education needs assessments was developed for retail grocery workers who use English or Spanish as their primary language. The needs assessment collected information on worker demographics, existing food safety knowledge, previous food safety training, literacy level, preferred educational delivery methods, and applicability of current educational materials. Part C: We developed bilingual (English/Spanish) food safety graphic signs, and studied their comprehensibility and most effective delivery mechanism for presentation to food handlers. The food safety concepts developed into images were: 1) cross-contamination, 2) proper use of thermometer to check temperatures of foods, 3) proper cooling of foods, and 4) do not work with food if ill. The four food safety concepts were designed in three different formats: pictures only, pictures with words (English/Spanish), and lenticular (images that shift when viewed from different angles). The food safety signs were evaluated by individuals working in the food retail industry. The participants were divided into two groups according to native language (English or Spanish). The ranking of comprehensibility of the signs was: cross-contamination (93%), thermometer (84%), cooling (64%) and not working if ill (33%). Low literacy levels as well as deficiencies in food safety training indicated a low understanding of the latter two of the sign concepts, and calls for food safety educational programs and materials that emphasize these concepts. Correct responses for sign presentation were as follows: pictures and words with (80%), pictures only (65%) and lenticular (62%). Comparison of three different formats indicated pictures with words as the most effective presentation. This study can be used as the basis for designing effective food safety signage for food handlers whose primary language may or may not be English. Also, this study contributes to understanding the roles of literacy and food safety training in the comprehensibility of food safety messages. Part D:Grocery store associates in the deli-bakery departments serve and prepare an increasing amount of ready-to-eat foods. This increases the need for a detailed, effective food safety training program in retail grocery establishments to prevent food borne illness. This research examines food safety knowledge, training preferences, needs, and current practices of grocery store deli-bakery employees in Southwest and Southern Virginia. This research had two phases. In Phase I: employees completed a thirty-four question needs assessment survey concerning background, food safety training needs, preferences and knowledge. In Phase 2: 15 employees (from phase 1 locations) food behaviors were observed for approximately six hours each. Observational data collection focused on glove use, cross-contamination, and hand washing. The results showed that most grocery food handlers desired hands-on, interactive and one-on-one training that occurs frequently, but is short: less than two hours in length. Overall, most grocery food handlers had general knowledge of safe food handling; however, the observational behavior data indicates behaviors do not reflect their knowledge. Greater than 95 percent understanding was found on the subjects of hand washing and glove use, however, bare hand contact with ready-to-eat foods and lack of hand washing prior to glove use were the items most often observed as practiced incorrectly. This study can be used as a basis for creating more effective food safety training efforts for retail or grocery food handlers. The creation of short, hands-on or interactive trainings for retail grocery food handlers, that focuses on changing food handling and preparation behaviors, may be more effective than other current training programs offered to these employees. Part E:Foodborne illness is a major concern for retail industries. This issue is compounded by lack of food safety training, cultural differences, and language barriers. In this study, researchers developed a customized, Spanish food safety training program that was used with employees of delicatessens (carnicerías) in Reading, Pennsylvania. The training program was designed to increase retention of food safety knowledge, improve attitude, alter behavior, and increase skills. Initially, needs assessments of employees were conducted by concealed-direct observations, a demographic survey, and a manager preference survey. Needs assessment data were used to develop a customized “counter-top” food safety training program that included images and oral supplementation in Spanish and addressed common food safety issues occurring in the carnicerías. Due to the low literacy level of participants, training was conducted on site via face-to-face (FTF) and in Spanish. The inclusion criteria for the carnicerías required that they have a meat display case, a meat slicer, employees >18 years, and employees who spoke Spanish as their first language. The findings of this study demonstrated that food safety attitude and behavior changes were not significant, although numerical improvements were observed. While many participants were illiterate and only spoke Spanish, the training program did successfully increase knowledge and teach proper food safety skills, indicating an intervention can be created for nearly any audience. A “counter-top” food safety training program could impact positively on retail establishments to improve food safety practices of their low literacy, Spanish-speaking, employees. The increased knowledge and improved food safety skills should benefit directly the citizens who use the carnicerías on a daily basis, in part because of the decreased risk of foodborne illness that results from the increased knowledge. Part F: We developed, printed and distributed the "Serving Safe Food" food safety training program for low literacy, Spanish-speaking workers in the retail grocery and foodservice industries. This training program is written in both English and Spanish and includes the following 6 lessons: The ABC’s of food safety at the grocery store Personal hygiene Handwashing and glove usage The flow of foods in the grocery store – Purchasing, receiving & storing The flow of foods in the grocery store – Handling, preparation, cooking & displaying Sanitation practices at the grocery store This educational tool can be used by grocery stores, supermarkets and convenience stores to train their Spanish-speaking employees in short periods of time. This flipchart training program contains strategies that take into account specific cultural attributes of Hispanic workers in the industry. The “Serving Safe Food” program can be presented to individual employees by any department supervisor, quality control personnel, Extension educators, and/or industry consultants who wish to conduct food safety training at a food retail establishment. English and Spanish speaking workers can be trained using this program.

OUTPUTS: The overall goal of this project is to develop, evaluate and deliver educational materials and training programs to enhance retail or grocery store food safety. Retail grocery industries may not be able to allocate sufficient time, money or personnel toward food safety training for their employees. Additionally, high employee turnover and increasing numbers of workers who do not read English well are important barriers to effective training. This project will emphasize grocery stores or supermarkets since they not only have these concerns, but also are increasingly conducting more in-store food preparations, such as slicing, cooking, packaging, and cold-holding. In 2012, one project goal was to enhance the effectiveness of Spanish language ServSafe food safety training for food retail establishments. The ServSafe Food Protection Manager Certification is a nationally recognized and accredited food safety training course for employees who work at restaurants, retail, deli stores and other foodservice outlets. Most counties in Pennsylvania require that there should be at least one certified employee at each food establishment and the certified manager must be accessible at all times during facility operation hours. The ServSafe food safety training program is owned by the National Restaurant Association and more than 3 million people have been certified to date. To improve the pass rates of the ServSafe certification exam taken by Spanish-speaking employees of food retail establishments, we applied basic adult education principles and spent more face-to-face time in the classroom with enrolled students. In 2012, we conducted six Spanish language ServSafe courses, and additional courses will be conducted in 2013. PARTICIPANTS: Nothing significant to report during this reporting period. TARGET AUDIENCES: Hispanic and/or Spanish-speaking workers in food retail and foodservice industries. PROJECT MODIFICATIONS: Nothing significant to report during this reporting period.

Impacts
For the ServSafe food safety program, any person who wishes to get certified as a food safety manager should pass the ServSafe test with a 75 percent score. Hispanics tend to have a lower rate of passing test scores in this program. The improved instructional efforts have led to higher average test scores, greater retention of knowledge, and a higher pass rate on the ServSafe exam. We will complete an in-depth study of test scores and pass rates after we complete additional Spanish training courses in 2013. The strategies used for the Spanish language ServSafe certification tests will enable more restaurant managers and other employees to pass the exam and to ultimately enhance food safety practices in their establishments.

The inclusion criteria for the carnicerias required that they have a meat display case, a meat slicer, employees >18 years, and employees who spoke Spanish as their first language. The food safety "counter-top" training program included four different assessments: knowledge, attitude, behavior, and performance of a skill (hand washing). The assessments were given pre-training (2 weeks prior), post-training (2 weeks after) and delayed- post training (3 weeks after the post-test). The findings of this current study demonstrated that food safety attitude and behavior changes were not significant, although numerical improvements were observed. While many participants were illiterate and only spoke Spanish, the training program did successfully increase knowledge and teach proper food safety skills, indicating an intervention can be created for nearly any audience. A "counter-top" food safety training program could impact positively on retail establishments to improve food safety practices of their low literacy, Spanish-speaking, employees.
