Consumer's Fresh Produce Food Safety Practices: Outcomes of a Fresh Produce Safety Education Program

ABSTRACT:  The Centers for Disease Control and Prevention estimate that there are 76 million cases of foodborne disease annually. Foodborne disease is usually associated with beef, poultry, and seafood. However, there is an increasing number of foodborne disease cases related to fresh produce. Consumers may not associate fresh produce with foodborne disease or recognize that these foods require safe handling. To address this learning need, a 1-h educational program was developed and evaluated. Extension agents in 69 Texas counties presented the program to participants. Most participants ( n  = 2651) were female (89.5%), Caucasian (60.5%), and over age 55 (62%). Participants completed a traditional pretest and then a retrospective posttest at conclusion of the program to assess knowledge, attitudes, and behaviors related to fresh produce safety. Participants' behaviors and attitudes were assessed using a 5-point scale. To measure the longer-term impact of the program, a follow-up telephone survey was conducted among a random sample ( n  = 426) of participants. Repeated measures ANOVA, t -tests, and eta-squared were used to determine significant differences. Immediate posttest results indicated improved knowledge and attitudes regarding specific fruit and vegetable safety recommendations. Long-term improvement was also noted for food safety behaviors, but not for overall food safety attitudes. The results suggest that this educational program is an effective tool to teach consumers about safe handling of fresh produce.     

Food Safety Knowledge and Beliefs of Middle School Children: Implications for Food Safety Educators

ABSTRACT: To create effective educational interventions that address the food safety informational needs of youth, a greater understanding of their knowledge and skills is needed. The purposes of this study were to explore, via focus groups, the food‐handling responsibilities of middle school youth and obstacles they face in practicing safe food handling and develop recommendations for the design of food safety interventions for youth. Most youth reported that they prepared food at least once weekly and rated learning to prevent foodborne illness as important. Youth knew that food could make them sick, described foodborne illness as resulting from “something” getting into food, not cooking food “right,” or the food going bad. Most responses lacked details, suggesting knowledge was basic. Nearly all were interested in learning about food safety. Barriers that deterred them from learning about food safety were time and feeling they were not susceptible to foodborne illness. To overcome barriers, youth suggested focusing on the seriousness of and risks for foodborne illness, using a serious but comical educational approach, and using hands‐on educational media. Parents highly rated the importance of and degree to which they wanted youth to learn about food safety. Parents felt that their children had moderate levels of food safety knowledge, but many questioned whether they practiced food safety procedures when unsupervised. Parents felt that food safety education needed to be taught and reinforced in school and at home. After having reviewed youth and parent data, food safety experts proposed recommendations for youth‐focused food safety education that paralleled current consumer food safety initiatives.     

Knowledge Assessment of Food Safety Managers in Utah and Its Implications on the Exam and Instruction

ABSTRACT: Food Safety Manager's Certification is offered through a state‐local Extension partnership in Utah using an online course management system. Exams and course materials were created by an Extension Specialist at Utah State Univ. Extension Agents provide exam and curriculum facilitation in each county. This form of distance education enables access for students in all 29 Utah counties. All 454 students (Jan 2008–Mar 2009) successfully passed the food safety managers exam in 1 or 2 attempts and received certification. Twenty‐nine percent of those taking the exam received certification without accessing any of the course materials. The overall passing exam score mean was 82%. When combining both passing and failing exam attempts, the students' mean was 79%. The students' mean of the lower 25% was only 65%. When evaluating the 7 food safety knowledge domains, students' means were highest in personal hygiene and lowest in facility, equipment, and layout. The lower 25% of students failed to score 70% in 6 of 7 food safety knowledge domains. The English course materials were provided in 3 options where students could select 1 or more: online, textbook, and DVD. For students who chose to access educational materials 67% used online learning, 40% textbooks, and 10% DVDs as part of their study options. Extension Agent feedback on Hispanic students enrolled in the program indicates a need for Spanish language study materials. Overall, the Utah Food Safety Managers program demonstrates a successful state‐local Food Science Extension approach to distance education, online curricula, and the use of computers to facilitate testing and learning.     

Food Safety Training Needs of Child Care Providers

Millions of children are cared for in child care centers or family day care homes. The care environment can be a significant source of foodborne pathogens if proper food safety practices are not followed by caregivers. To decrease children's risk of foodborne illness, caregivers must know and apply safe food handling practices. To identify what care providers need to know about safe food handling, and how they want to learn, needs assessment research was conducted with a random sample of child care centers and family day care homes in Michigan (n=335). Research Findings. Results indicate that persons who care for young children in licensed centers or homes wanted to know more about the relationship between food and illness. Specifically, they wanted information about what causes food to become unsafe and how to prevent foodborne illness in the child care environment. Providers in both centers and homes preferred print materials (booklets, fact sheets, and newsletters) to videotapes, audiotapes, workshops, teleconferences, or an informational hotline. Implications for Practice. Developing and providing food safety booklets, newsletters, and/or fact sheets which include application-oriented and understand- able food safety information consistent with licensing regulations could reduce the risk of contracting foodborne illness of young children cared for in child care centers or day care homes.     

Assessing the Food Safety Knowledge of University of Maine Students

Foodborne illness is a global public health issue. Young adults may work in foodservice while they are university students, and their habits may later shape the practices and well‐being of their children. The objective of this study was to establish baseline data and assess the food safety knowledge of 18‐ to 26‐year‐old Univ. of Maine students. Demographic questions and the previously validated Food Safety Knowledge Questionnaire (FSKQ) were placed online. Of 123 people who responded to the email recruitment notice, 104 Univ. of Maine undergraduates aged 18 to 26 years completed the survey. The average score among all participants was 60% correct (53 points out of a possible 89 points). Survey questions that required participants to identify common sources of foodborne pathogens had the lowest average percent correct (31%). Less than 50% of participants were able to correctly identify several high‐risk foods, including sliced melon, raw sprouts, and unpasteurized fruit juice. Our findings indicate a need for educational programs for 18‐ to 26‐year‐old Univ. of Maine students in regards to common sources of foodborne pathogens and proper handling of fresh produce and that food safety knowledge among university students has not improved since publication of a national survey using the FSKQ in 2006. Effective educational programs are needed to ensure that young adults understand food risks and appropriate food handling practices.

Development of a Reality‐Based Multimedia Case Study Teaching Method and its Effect on Students’ Planned Food Safety Behaviors

There is opportunity to decrease the frequency of foodborne illnesses by improving food safety competencies and planned behaviors of college students before they begin careers in the food industry. The objectives of this study were to (1) develop a multimedia case study teaching method that provides real world context for food science education; and (2) evaluate the extent to which it improves the intentions of students to implement food safety management systems upon entering the workforce, as well its impact on knowledge gains and students’ abilities to understand complex concepts. The target audience consisted of all participants in an upper‐level undergraduate food safety management systems course (n = 17). A pretest and posttest survey research instrument was developed to measure knowledge gains and also students’ food safety intentions using the framework of the Theory of Planned Behavior. Students experienced significant gains in knowledge, attitude, and intention after completion of the course (P < 0.05). One hundred percent of students agreed that the interactive videos aided in their understanding of food safety concepts. A paired t test suggested that both behavioral control beliefs and attitudes of students toward food safety management significantly increased (P < 0.5) after completion of the case study. These results suggest that integrating multimedia case studies into food science education may enhance food safety behaviors.     

Investigating Change in Adolescent Self‐Efficacy of Food Safety Through Educational Interventions

A successfully targeted intervention can influence food safety knowledge, attitudes, and behaviors, as well as encourage participants to recognize their own responsibility for safe food handling. This acknowledgement of an individual's responsibility and capacity to address food safety can be understood as self‐efficacy of food safety (SEFS). This study investigated the impact of a specific educational intervention, Hands On: Real‐World Lessons for Middle School Classrooms, curriculum on SEFS in adolescents and was guided by two research questions: (1) to what extent can an existing food safety curriculum impact students’ SEFS, and (2) to what extent does a relationship exist between changes in self‐efficacy and changes in food safety behavior, particularly when controlling for knowledge gains. A total sample of 424 students across 6 states participated in this study. Teachers were trained to implement the Hands On program in their classrooms and then students were administered a pre‐ and posttest to measure the impact of the program on knowledge, food safety‐related behaviors, and SEFS. The data indicated that there is a strong predictive relationship between SEFS and positive behavior change. Additionally, the Hands On program was effective at increasing students’ SEFS.     

Development and Implementation of a Food Safety Knowledge Instrument

ABSTRACT:  Little is known about the food safety knowledge of young adults. In addition, few knowledge questionnaires and no comprehensive, criterion-referenced measure that assesses the full range of food safety knowledge could be identified. Without appropriate, valid, and reliable measures and baseline data, it is difficult to develop and implement effective education efforts. Thus, the purpose of this study was to develop a comprehensive, valid, reliable food safety knowledge questionnaire. Questionnaire development followed this process: 1) use of published reports and input from experts in food safety and sanitation (n = 7) to identify key food safety concepts; 2) development of a question bank (n = 101) assessing knowledge of key concepts (i.e., cross contamination prevention'disinfection procedures; safe times/temperatures for cooking/storing foods; groups at greatest risk for foodborne disease; foods that increase risk of foodborne disease; and foodborne disease pathogens); 3) refinement of initial questions by experts; 4) questionnaire pretest with young adults (n = 180) and refinement; 5) questionnaire pilot test (n = 126) and refinement; 6) final expert review and refinement; and 7) conversion into an online survey. Young adults (n = 4343, mean age 19.9 ± 1.7SD years) from 21 universities and colleges across the country completed the questionnaire. Item analysis was used to determine the overall quality of the test and identify improvements needed. Livingston's coefficient of reliability for criterion-referenced tests was 0.92. The questionnaire met or exceeded generally recognized standards of reliability and validity. This questionnaire could be useful in baseline assessment of food safety knowledge and measurement of knowledge gained after an educational intervention in adults.     

Development,Dissemination, and Assessment of a Food Safety Systems Management Curriculum for Agribusiness Students in Armenia

This study addresses the development, dissemination, and assessment of a Food Safety System Management (FSSM) curriculum offered to college‐aged, agribusiness students in Yerevan, Armenia. Prior to beginning the program, demographic data were collected and a paper‐based pretest was administered to access the food safety knowledge, behavior, and attitude of participants (n = 29). For assessment of a skill, participants’ handwashing techniques were videotaped and scored before the program commenced. Immediately after completion of the entire curriculum, a paper‐based post‐test with identical questions for food safety knowledge, behavior, and attitude was administered and handwashing skills were assessed. ANOVA with repeated measures was used to evaluate significant differences (α = 0.05) for food safety knowledge using a pretest, post‐test, and a 3‐mo follow‐up. A paired t‐test was used to evaluate handwashing skills before and after the curriculum was presented. The pretest score (44.93%, ± 2.87) for food safety knowledge (n = 29) differed significantly (P <0.0001) when compared with the post‐test score (73.21%, ± 3.28) and the 3‐mo follow‐up (n = 23) score (67.76%, ± 3.93). Participants’ (n = 9) handwashing skills prior to delivery of the FSSM curriculum differed significantly (P <0.0001), when compared to handwashing skills after completion of the curriculum. Students’ food safety attitudes and behavior assessed using a five‐point Likert scale, also improved significantly as a result of the FSSM program. The 3‐mo follow‐up survey on food safety attitude and behavior was consistent with the post‐test survey results. The information from this project may be of interest to education experts, Extension professionals, food industry personnel, or regulatory agencies, in the development and dissemination of an international food safety program.     

Development,Dissemination, and Preimplementation Evaluation of Food Safety Educational Materials for Secondary Education

Abstract: With the persistence of microbiological foodborne illness and anticipated future shortage of scientists with agricultural and food science expertise in the United States, it is imperative to educate youth on microbiological food safety and enhance their awareness of opportunities to become engaged in finding solutions to food safety challenges. To help integrate food science education across the high school curriculum, new educational materials on microbiological food safety were developed and then disseminated to and evaluated by educators of secondary basic and applied sciences. The materials present food safety concepts in the context of foodborne illness outbreaks to introduce basic concepts of food microbiology, epidemiology, and food safety strategies as well as their broad impact on economics, communication, and regulations. The ready‐to‐implement educational materials support educational content standards and various learning styles and encourage critical thinking skills. The materials include a presentation on food microbiology and foodborne illness surveillance, case studies on foodborne illness outbreaks, a video on the laboratory investigation of foodborne illness, interactive web‐based activities, and supporting materials for teachers and classroom display. Exposure to the materials in a 1‐d workshop positively impacted educator familiarity with general microbiology, food safety strategies, regulatory requirements, and associated terminology as measured by a test administered prior to and after use of the materials. Teachers of biology, chemistry, family and consumer sciences, and related sciences rated the materials favorably on applicability, anticipated ease of implementation, and anticipated reception by students.     

Validation of an Interdisciplinary Food Safety Curriculum Targeted at Middle School Students and Correlated to State Educational Standards

ABSTRACT:  Providing effective food safety education to young consumers is a national health priority to combat the nearly 76 million cases of foodborne illness in the United States annually. With the tremendous pressures on teachers for accountability in core subject areas, the focus of classrooms is on covering concepts that are tested on state performance examinations. As a result, topics such as food safety are rarely addressed in middle school classrooms. Middle school is an ideal time to teach food safety because adolescents are in the process of setting lifelong behaviors; therefore, they are more likely to synthesize new food safety knowledge in a way that will lead to the development of lifelong behaviors. The purpose of this study was to scientifically validate an educational resource that provides a method for classroom teachers to involve young consumers in food safety education while meeting state content area curriculum standards. An interdisciplinary curriculum targeted at middle school students and correlated directly to state content standards was designed to include highly effective instructional strategies that teach food safety concepts through all core subject classes (science, math, social studies, and language arts). The curriculum was pilot tested in 5 schools using a pretest, posttest, and follow-up test assessment model. The results showed that the curriculum was highly effective at raising student knowledge (21% gain) and improving students' food handling behaviors (8.47% gain) from pretests to posttests. In addition, 6 wk after implementation, students retained 86% of their total knowledge gain as measured by a follow-up assessment.     

Development and Pilot Testing of a Food Safety Curriculum for Managers and Staff of Residential Childcare Institutions (RCCIs)

Food safety training materials, targeted for residential childcare institution (RCCI) staff of facilities of 20 residents or less, were developed, piloted, and evaluated. The goal was to assist in the implementation of a Hazard Analysis Critical Control Points (HACCP)‐based food safety plan as required by Food and Nutrition Service/United States Department of Agriculture. RCCI staff and instructor training manuals, Food Safety Basics: Food Safety Education for RCCIs was developed and pilot tested in RCCIs in both Rhode Island and Massachusetts. The program was evaluated by participants and pre‐/posttraining onsite inspector and microbial assessments. The core curriculum contained 3 modules and corresponding activities: Module 1: cause, prevention, and strategies to reduce foodborne illness; Module 2: components of a HACCP‐based food safety plan and standard operating procedures; and Module 3: actual food safety plan development, including instructions for implementation and corresponding monitoring procedures required. There were 50 to 82 RCCI staff members that attended 2 or 3 modules. Participants rated the modules 4.5 ± 0.4, 4.3 ± 0.4, and 4.4 ± 0.4 out of 5‐point Likert scale (1 = strongly disagree, 5 = strongly agree) for teaching modules 1, 2, and 3, respectively. The evaluations assessed their understanding of key topic areas taught. Onsite inspections showed improvement in many critical food safety issues. Some deficiencies still appeared to be problematic, such as refrigerator temperature monitoring and issues with storage and cross‐contamination.     

Assessing and Addressing Safe Food Handling Knowledge,Attitudes, and Behaviors of College Undergraduates

ABSTRACT: The authors determined the food safety knowledge, attitudes, and behaviors of undergraduates (n = 1122) on an urban college campus using a previously piloted survey tool. Data obtained found that while students reported high levels of confidence in their ability to engage in safe food handling practices, their knowledge and self‐reported behaviors indicated that they were not actually engaging in safe food handling practices. Students were particularly lacking knowledge with respect to proper temperatures for cooking, reheating, and refrigerating foods. The data were further analyzed to determine differences in food safety knowledge and practices between populations of different demographics within the students. Differences were found between male and female students, Caucasian and Asian students, and students who had worked in food service compared with those who had not. A final aspect of this study evaluated the effectiveness of a social marketing campaign to increase awareness of safe food handling practices among college undergraduates. A cross‐sectional, quasi‐experimental, pre‐ and posttest design was used. Following the baseline knowledge survey described previously, a social marketing campaign developed for young adults was implemented on the campus over a 4‐wk period that included promotional events and incentives. Postcampaign survey results indicated increases in food safety knowledge, attitudes, and behaviors, particularly with respect to appropriate temperatures for cooking and refrigeration and found that e‐mails and posters may be effective ways to communicate food safety messages to this population.     

Seeing Is Believing: Effective Components of Professional Development Training for County Extension Educators on an Innovation Perceived as Risky—Food Irradiation

ABSTRACT: Decades of research have provided evidence that food irradiation is a safe technology that can decrease the incidence of foodborne diseases; however, adoption of this technology has been slow. The purpose of our study was to qualitatively explore the effectiveness of various components of a professional development training on family and consumer sciences county extension educators' understanding of food irradiation. This training included presentations by experts in the field, a tour of a food irradiation research facility and a meat processing facility, group activities, and a computer simulation model. Data were collected using qualitative research methodology through in-depth interviews conducted after the training. Results indicated that those components that allowed participants to visualize food irradiation processes seemed most beneficial to their understanding. Based on these data, implications for practice are discussed.     

The Relationship between Attitudes, Knowledge, and Demographic Variables of High School Teachers Regarding Food Irradiation

ABSTRACT:  The purpose of this study was to use a validated instrument to determine the attitudes and knowledge of high school teachers regarding food irradiation, and to determine the correlations among their knowledge and attitudes and certain demographic variables. Knowledge and attitudes about food irradiation were measured in selected high school family and consumer sciences teachers ( n = 121) who taught Food and Nutrition, Food Science and Technology, and/or Food Production Management and Services, via a 24-item instrument with 6 factors. Results revealed these teachers held neutral to positive attitudes about the safety of irradiated foods, their perception of the risk of foodborne illness, and learning about food irradiation, and neutral to negative perceptions of their understanding of food irradiation and their competence to teach about it. These teachers had a moderate knowledge base regarding food irradiation. Teachers' attitudes regarding the safety of food irradiation were positively correlated with their perceived understanding of food irradiation, actual knowledge of it, and competence to teach about it. Their perceived understanding of food irradiation was positively correlated with competence to teach about it, knowledge, and attitudes toward the safety of food irradiation. The only demographic variable correlated with knowledge or attitudes was teachers' previous food irradiation educational experiences. These data suggest the importance of education for family and consumer sciences teachers concerning food irradiation.     

Implementation and Assessment of Food Safety Educational Materials for Secondary and Postsecondary Education

Previous studies have reported on the inadequacy of youth knowledge and practice of food safety principles. The formal high school science classroom environment presents an opportunity to stimulate interest and increase knowledge in food safety with potential benefits to students in improved science literacy, development of life skills, and greater awareness of career opportunities. Previously developed educational materials, Foodborne Illness Outbreak Investigations for Food Safety Education, were evaluated for instruction by high school and community college science educators of various subject matters including foods, microbiology, disease, and chemistry courses. Educator feedback was favorable on measures of quality, implementation ease, and student engagement, with ratings greater than 3 on a 5‐point scale corresponding to “good” to “excellent.” A positive change in familiarity with food safety concepts for 4 groups of students, representing approximately 77% of the participants, was demonstrated by an overall increase, ranging from 4% to 14%, in correct responses to a test administered before and after exposure to the materials. There was variation in degree of change and the topics positively impacted for student groups by subject matter.     

Development of an Evaluation Tool for Online Food Safety Training Programs

Abstract: The objective of this study was to provide the person in charge and food safety instructors an assessment tool to help characterize, identify strengths and weaknesses, determine the completeness of the knowledge gained by the employee, and evaluate the level of content presentation and usability of current retail food safety training platforms. An existing evaluation tool was modified to assess online food safety training programs that contained 5 areas of emphasis: content and instruction, learners, job transfer, design and packaging, and operation. Participation included watching 3 food safety training modules and afterwards evaluate what degree the module content met objectives. More than 85% of the participants responded positively to the scale‐based items of the course evaluation. Items addressing the content and instruction received positive responses. The assessment tool helped panelists to objectively evaluate an online food safety training program that provided numeric data for a valid comparison.

Are Older Adults Prepared to Ensure Food Safety During Extended Power Outages and Other Emergencies?: Findings from a National Survey

Natural disasters and other emergencies can cause an increased risk of foodborne illness. We conducted a nationally representative survey to understand consumers’ knowledge and use of recommended practices during/after extended power outages and other emergencies. Because older adults are at an increased risk for foodborne illness, this paper presents findings from a sample of older adults (n = 290). Only 17% of respondents reported they are fully prepared to keep food safe during an extended power outage. Respondents identified lack of cogitation (42%), storage space (19%), and concern (27%) as barriers to not being fully prepared. Of those who had experienced a recent power outage, less than 40% followed the recommended practices of discarding frozen foods that had thawed and discarding refrigerated, perishable foods. Additionally, 21% to 36% of respondents reported they tasted food to determine whether it was safe to eat. Awareness and likelihood of following recommended practices were higher among women than men. Many older adults are not following recommended practices to ensure food safety during/after extended power outages and other emergencies. Educational materials need to address barriers and be tailored to specific locations and subpopulations of older adults. Educators and public health officials can use the survey findings to address gaps in older adults’ knowledge and practices and to help reduce the risk of foodborne illness among older adults.
