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.     

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.     

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.     

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.

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.     

Food Safety Education Using Music Parodies

ABSTRACT:  Musical parodies of contemporary songs with their lyrics altered to address current food safety issues were incorporated into a variety of food safety educational programs and the effectiveness of the music was evaluated by semiquantitative and qualitative measures. Audiences receiving the music-enriched curricula included school foodservice supervisors, school foodservice managers, culinary arts instructors, culinary arts students, Family and Consumer Sciences teachers, and youth aged 8 to 12 y and studies were conducted in South Carolina, North Carolina, and Delaware. Among school foodservice supervisors, school foodservice managers, and culinary arts students, most participants were able to recall the main points of each song that was introduced in the curriculum. The culinary arts students were less likely to recall the main points of each song than were the other 2 groups, possibly because of the lack of prior knowledge of food safety practices as well as a lack of preference for the style of songs used. Family and Consumer Sciences teachers were enthusiastic about the use of the music but also identified potential barriers to the successful use of the music, due to the potential lack of appropriate audiovisual equipment, a lack of skills in using such equipment, and time constraints for the use of music in curricula due to the strong emphasis on end of year testing. Participants in the summer youth groups demonstrated significant increases between pre- and posttest examinations of safe food handling behaviors and most were able to quote lines or phrases from the songs.     

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.     

Increasing Content Knowledge and Self‐Efficacy of High School Educators through an Online Course in Food Science

Purdue Univ.'s College of Agriculture developed an Advanced Life Sciences (ALS) program in partnership with several high schools across Indiana. As part of ALS, secondary educators take an introductory food science (FS) course (ALS‐Foods) and teach it at their high school. High school students taking the ALS‐Foods receive dual credit for an introductory course required for all FS majors at Purdue. The goal of this project was to develop an online course to improve content knowledge and self‐efficacy of secondary educators in the field of FS. The course was offered over a 3‐wk period and consisted of 3 learning modules focused on food chemistry, food microbiology, and food processing. Modules included class activities, videos, study questions, and teaching tools. Participants were assessed on content knowledge through written assignments, quizzes, and a final examination. Twenty secondary educators from several states were enrolled. Overall, content knowledge increased significantly (P < 0.05) across all 3 modules after completing the course. Highest scores were in food microbiology/safety (84%), followed by food processing (76%) and food chemistry (70%). A precourse survey indicated that the majority (>80%) of participants felt they had “no‐confidence” to “little‐confidence” in teaching FS concepts related to the 3 modules. Upon completing the course, the confidence level of all participants increased to “some‐confidence” or “complete confidence.” By strengthening the knowledge level of secondary educators, they will be better prepared to teach FS and subsequently, more high school students could be exposed to FS and consider it as a career.     

‘School doesn't feel as much of a partnership’: parents' perceptions of their children's transition from nursery school to Reception class

This small‐scale study explores a group of English parents' perceptions of their relationships with their child's nursery school and, after the transition to Reception class, their primary school. It references current research and literature on the issues of transition and the role of parents in their children's education. Findings from semi‐structured interviews with parents, and with the children's key workers, were analysed for emergent themes. Parents felt very positively about their relationship with their child's nursery, and that they were fully involved in, and informed about, their child's learning. However, the transition to school heralded a change in their relationships. Most parents felt that they had a more distant and less reciprocal relationship with their child's teacher than they had had with their key worker at nursery. The paper concludes with recommendations for further research.     

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.     

Assessment of an online piloted module targeted toward home‐based food operators in Iowa

Understanding safe food practice is important for home‐based food operators to prevent foodborne illness. Earlier work has found that home‐based food operators lack food safety knowledge and may benefit from training that is specifically tailored to their needs. Unfortunately, home‐based food operators may be deterred from enrolling in traditional educational formats due to their busy schedules. The objective of this study was to pilot and evaluate the effectiveness of an online food safety education module for home‐based food operators in Iowa through three learning assessments. Twenty‐one participants enrolled in a blended workshop in which participants completed one online module before attending a face‐to‐face session where they completed the remaining five modules. The effectiveness of the online module was measured by examining the first‐attempt average scores on learning assessments, the number of assessment attempts required to achieve 100%, and the first‐attempt performance by question type. The three learning assessment tools resulted in first‐attempt averages of approximately 86%, 90%, and 83%, surpassing our standard of effectiveness of 75% and showing good potential for the online format. The learning assessment attempt numbers of 4.65, 1.67, and 3.81 showed difficulty with knowledge transfer for some topics. Comprehension and analysis‐style questions had first‐attempt success rates of approximately 85% and 88%, respectively. Scores on knowledge and application‐style questions were lower with first‐attempt success rates of approximately 80% and 75%, respectively. These findings were used to improve the first online module and guide the transition of the remaining five modules to the online format.     

Self-Reported Changes in Food Safety Behaviors among Foodservice Employees: Impact of a Retail Food Safety Education Program

ABSTRACT:  A food safety education program developed for retail food establishments was evaluated to assess the extent to which participants were practicing selected behaviors linked to reducing the risk of foodborne disease both before and after the program. Scores from the state health department's Certified Food Manager (CFM) exam also were examined. Based on the 189 usable surveys returned, most respondents were female, middle age, and white with nearly 11 y of foodservice experience. Results revealed that after completing the program, participants reported practicing behaviors related to hand washing, maintaining safe food temperatures, preventing crosscontamination, and pest management more frequently ( P < 0.05) compared to before the program. Effect size analysis indicated these results were also practically significant. Most (82.5%; n = 156) participants passed the CFM exam. Compared to those who failed the CFM exam, those who passed reported significantly higher changes in the adoption of selected behaviors; however, these results were of limited practical significance according to effect size analysis. Results suggest the food safety program is effective in promoting the adoption of food safety behaviors that can help reduce the risk of foodborne illness.     

Assessment of Knowledge and Behavior Change of a High School Positive Deviance Food Safety Curriculum

High school students are a critical audience for food safety. Students may enter the foodservice industry or become primary meal preparers for their families. The positive deviance food safety curriculum was developed based on the messages from the Fight BAC! Campaign. The curriculum is designed for high school students to overcome barriers to safe food handling practices. This study evaluated the effectiveness of the positive deviance approach to change food safety knowledge and behaviors among high school students. Students (n = 218) from two high schools participated in this study. The positive deviance method uses group discussions lead by the teacher who reinforces and praises behaviors, which reflect recommended food handling practices. Measurements included pre‐ and postsurveys, preobservations and postobservation cooking classes, take‐home tasks, and in‐class activities. Results indicated that the curriculum significantly increased students’ food safety knowledge. Specifically, the percentage of students believing that color was a good indicator of meat doneness dropped from 52% to 17% after exposure to the curriculum. When observed, the students’ compliance with recommended behaviors increased. Prior to instruction, most ground beef burgers students cooked did not reach 160°F, while after the intervention, almost all of the burgers reached 160°F or higher. The curriculum will benefit from a revision that emphasizes areas such as how to use, calibrate, and to clean food thermometers.     

Development and Evaluation of Food Safety Modules for K‐12 Science Education

Career and educational opportunities in food science and food safety are underrecognized by K‐12 students and educators. Additionally, misperceptions regarding nature of science understanding persist in K‐12 students despite being emphasized as an important component of science education for over 100 y. In an effort to increase awareness concerning career and educational opportunities in food science and food safety and to improve the nature of science understanding among K‐12 students, a series of problem‐based learning modules was developed and pilot tested with a total of 61 K‐12 students. Results of pre‐ and postevaluations and assessments indicated that (1) interest in science, food science, and food safety increased and (2) content knowledge related to the nature of science, food science, and food safety was improved. We further suggest that these modules provide opportunities for educators in traditional as well as extracurricular settings to demonstrate important concepts contained in the newly released Next Generation Science Standards.     

The educational implications of type i diabetes mellitus: A review of research and recommendations for school psychological practice

Type I diabetes mellitus (T1DM) is one of the most common chronic illnesses in children and youth, with many affected students requiring individualized services and supports within educational settings. This article systematically reviews the research regarding the implications of this illness for students' cognitive and academic functioning to clarify the ways in which this disease may limit children's learning and school performance. The authors synthesize the findings, summarize the related literature regarding school‐based supports, and provide recommendations for school psychologists to support the unique psychoeducational needs of this population. Results highlight the need for more research on effective school‐based interventions to ensure academic success for children with T1DM. © 2011 Wiley Periodicals, Inc.     

Identifying Food Safety Concerns When Communication Barriers Exist

Abstract: Students must be prepared to lead a diverse workforce. The objective of this study was to establish a teaching method that helps students identify barriers to food safety while working in a simulated environment with communication barriers. This study employed a perspective taking exercise based upon the principles of social learning theory. Students were randomly assigned as a “manager” or an “employee.” The managers were provided with a recipe and instructions in English and employees were provided with the recipe and instructions in an abstract, non‐English language. Students were instructed to prepare the recipe in silence using only nonverbal communication methods. Three teaching techniques were employed under this scenario to determine the most effective method of instruction. For the 1st method (Barrier Identification), students were asked to complete an open‐ended survey concerning their communication barriers in regards to food safety. Next (Modeling through Pictures), recipe books with pictures of each recipe with food safety icons were provided to half of the participants. In the 3rd scenario (Observation), students were videotaped to identify communication techniques and to identify common food safety violations. Lastly, a focus group was conducted, whereby students were required to reflect upon the experiment in order to identify specific food safety barriers. Students identified communication challenges to food safety and developed techniques to help overcome language barriers. However, the use of pictures did not increase the frequency of proper food handling procedures. This study found that a combination of gestures and demonstrations were the most valuable nonverbal forms of training.     

Food Safety Practices Assessment Tool: An Innovative Way to Test Food Safety Skills among Individuals with Special Needs

Abstract: This article describes an innovative assessment tool designed to evaluate the effectiveness of a food safety skills curriculum for learners receiving special education services. As schools respond to the increased demand for training students with special needs about food safety, the need for effective curricula and tools is also increasing. A Food Safety Education for High School and Transition Special Needs Students curriculum served as the basis upon which our assessment tool was developed. The project was a collaborative effort by food safety and education professionals in Connecticut, Rhode Island and Massachusetts. This USDA‐funded initiative emerged from teacher‐generated data that identified critical gaps in food safety knowledge and skills among students with disabilities (SWD) receiving special education services. As an adjunct to this curriculum, a Food Safety Practices Assessment Tool was developed to: 1) conduct observations of students as they demonstrate food safety practices, and 2) use this information to design classroom‐based learning activities that are aligned with students’ Individual Education Plans (IEP). Pilot data suggest that the tool is valid and reliable for use in a kitchen‐based setting. This is the first known tool of its kind to test food safety skills of individuals with special needs in a real‐world environment. Further testing is needed to determine the usefulness of the tool for broader audiences.
