Use of the Conceptual Change Teaching Method to Address Food Safety Among Native American and Hispanic Food Preparers

PurposeThe study examines the interrelationships of food safety knowledge, attitudes and practices, and the moderating effect of food safety training on the said interrelationships.Design/methodology/approachPredictive-causal was the primary research design used and partial least squares – structural equation modelling (PLS-SEM) was the statistical technique applied.FindingsResults showed that food safety knowledge significantly and positively influences attitudes towards food safety. It was further revealed that attitudes toward food safety and food safety practices are also significantly and positively related. Moderation analysis indicated that food safety training moderates the significant and positive relationship between attitudes towards food safety and food safety practices.Research limitations/implicationsThe present study has limitations. First, the unit of analysis is focused on food handlers in fast-food restaurants in Angeles City, Philippines. Other researchers may come up with similar studies on a larger scale – provincial, regional or national. Second, only food safety training as a construct was used as a moderator on the hypothesized relationships of the structural model. Other studies may expand and explore other moderating variables and/or mediating constructs that may affect the said hypothesized relationships.Practical implicationsBased on the present study, food safety knowledge was found to have a huge significant and direct influence on attitudes of fast-food restaurant food handlers towards food safety, as evidenced by the computed effect size. In short, knowledge on food safety is an integral factor when it comes to enhancing food safety attitudes of fast-food restaurant food handlers. When fast-food restaurant food handlers are well-equipped with the right food safety knowledge, they become more aware of the different food safety protocols and other pertinent food safety guidelines and procedures which can lead to favorable food safety attitudes.Social implicationsThe present study highlighted the moderating effect of food safety training on the relationship between attitudes toward food safety and food safety practices. Therefore, regular attendance of food handlers to food safety training is crucial in developing acceptable attitudes toward food safety, which in turn, favorably affect their food safety practices in fast-food restaurants.Originality/valueThe current study utilized PLS-SEM, a second-generation statistical technique, to measure the hypothesized relationships as compared to correlation tests performed by prior studies on the interrelationships of food safety knowledge, attitudes toward food safety and food safety practices. PLS-SEM is suitable for this type of research design – predictive-causal – since this study involves model development and prediction. Furthermore, it employed moderation analysis to measure the moderating effects of food safety training on the identified hypothesized relationships of the structural model. Hence, methodologically, the present study employed new ways and insights in measuring the interrelationships of food safety knowledge, attitudes and practices.

Food safety knowledge and practices are necessary for eliminating food borne diseases, however, there is a scarcity of information on food safety knowledge and practices among young adults in the Northern Region of Ghana. This research was therefore aimed at assessing the food safety knowledge and practices of university students in the Northern region of Ghana and to determine if any relationship exists between their food safety knowledge and practices and their socio-demographic and academic characteristics A cross-sectional study was carried out where data was collected from 397 randomly selected students of the University for Development Studies and Tamale Technical University using a questionnaire. Data was analyzed using SPSS V20. Results showed that 54.4% had good level of food safety knowledge, 38.5% had moderate level of food safety knowledge and 7.1% had poor levels of food safety knowledge. Similarly, students also showed 46.3%, 39.3% and 14.4% levels of good, moderate and poor food safety practices, respectively. The department and level of study significantly influenced (P < 0.05) the food safety knowledge of participants, however no demographic characteristics influenced (P > 0.05) the food safety practices of the participants. The findings from this study suggest the need for increased effort on how to guide students to translate their food safety knowledge into practice. Innovative and creative approaches should be applied to food safety education to increase practice since the students showed good food safety knowledge than food safety practice.

This study examined the current status of foodservice management in elderly welfare facilities and evaluated food service workers' food safety practices and knowledge. For this, the directors of 20 elderly welfare facili- ties (each with fewer than 50 residents) located in Seoul were interviewed and a survey of 40 foodservice workers was conducted to determine their food safety knowledge and practices. The facilities accommodated an average of 28 residents. All the facilities were self-operated and approximately 62% were dependent on payments by residents. Only 15% had a dietitian in charge of menu planning, food purchasing, and food safe- ty management. Approximately 50% had their facility managers take responsibilities for menu planning and food safety management. Most of the facilities provided food safety training within their own facility and sa- nitized their utensils, cutting boards, and dishcloths on a daily basis. A limited number of foodservice work- ers, insufficient training programs, and budget constraints were some of the major barriers to food safety management. Their average score on food safety practices was 1.62, and that on food safety knowledge was 17.6 out of 19 points. These results indicate that the foodservice workers had good food safety knowledge and appropriate food safety practices. There was a significant correlation only between food safety practices related to receiving and storing food products and knowledge of personal hygiene.

Food safety receives minimal attention and only captures national attention during foodborne disease outbreaks. The objective of this study was to explore the knowledge, attitudes and practices on food safety aspects related to Orange Fleshed Sweet potato (OFSP) along the food value chain in Kenya. A cross-sectional study was designed and investigated food safety knowledge, attitudes and practices (KAP) among the OFSP processors, traders, and consumers of street foods in Kenya. A socio-demographic questionnaire and KAP questionnaire were used as data collection instruments. The study included OFSP traders OFSP puree processors, large retailer’s bakeries and consumers in Nairobi. The OFSP traders included were the suppliers of OFSP in the markets around Nairobi city. The OFSP consumers included the people who buy cooked OFSP from the street vendors in Nairobi city. Descriptive statistics such as percentage means and standard deviation were used to summarize the socio-demographic data and the knowledge, attitude, practices, and overall KAP. Pearson’s correlation was used to establish an association of the three study components. Adjusted linear regression was used to assess the effect of food safety on knowledge, attitude, and practices. Knowledgeable, positive attitude and good practice on food safety were considered for mean scores above 80%. Statistical significance was set at p < 0.05 . The findings from the OFSP processors revealed a mean percentage score for knowledge, attitude, practices at 70.7%, 93.5%, and 90%, respectively, with an overall mean score of 84.6%. Lower education level was statistically significantly associated with food safety practices at p = 0.002. Adjusted linear regression found a significant effect of food safety on knowledge at p<0.001. Adjusted multiple regression revealed that age was statistically significantly associated with food safety knowledge, and food safety attitude (both at p <0.001). Education level was significantly associated with food safety practices (p<0.001). Findings from OFSP traders revealed mean percentage scores for knowledge, attitude, practices at 63.1%, 74.4%, and 64.7%, respectively, with an overall mean score of 67.4%. Pearson’s correlation analysis revealed a strong positive correlation between food safety attitude and food safety practice p= 0.015. Similarly, a strong positive correlation between food safety practice and food safety knowledge was noted (p <0.001). Adjusted linear regression found that Food safety practice was significantly impacted by both knowledge and attitude R2=0.578 F=49.6 p=0.000. Results from OFSP consumers revealed mean percentage scores for knowledge, attitude, practices at 66.2%, 87.3%, and 91.6%, respectively with an overall mean score of 81.7%. Lower education level was statistically significantly associated with inappropriate practices among OFSP consumers p = 0.040. Pearson’s correlation analysis revealed a week positive correlation between food safety knowledge attitude and practice. : This study reveals a gap in the area of food safety knowledge, attitude, and practice along the OFSP value chain. The study highlights the need for policymakers to address and review the knowledge, attitude, and practices in the food industry, to raise food safety awareness campaigns and organize more targeted training along the food chains to reduce the foodborne disease burden.

Food safety knowledge and self-reported practices among school children in the Ga West Municipality in Ghana

Many food recovery agencies depend on donated food, and its safety is critical for the health of vulnerable populations. A food safety curriculum was developed for agency volunteers and paid staff of the Lower Mississippi Delta region. Examples of topics in the curriculum included: personal hygiene, food storage, transporting food safely, and HACCP. Food Safety Knowledge Pre- and Posttests (20 questions) were identical, and validity and reliability were established prior to use. Paired t-tests were performed to determine the effectiveness of the curriculum (n=190). A Food Safety Practices Survey (10 questions) demonstrating attitudes and behaviors regarding food safety practices in the agency and/or the home was given with the Food Safety Knowledge Posttest. The heading on the survey was, “After the food safety training today I plan to,” and possible responses were “already doing,” “yes,” or “no.” A Food Safety Practices Delayed Survey was administered by mail to participants 3-6 months following the food safety training. The Food Safety Practices Delayed Survey was similar to the Food Safety Practices Survey except there were four possible answer choices-- “always,” “most of the time,” “sometimes,” and “never.” Food Safety Knowledge Posttest scores (19.0 ± 0.1) were significantly (p<0.000) greater than Food Safety Knowledge Pretest scores (16.6 ± 0.2). Food Safety Practices Survey results indicated that participants were already using proper food safety practices (5.8 ± 0.2), or that they plan to use proper food safety practices (4.0 ± 0.2). On the Food Safety Practices Delayed Survey (n=82) participants indicated that they “always” (8.8 ± 0.2) or “most of the time” (0.8 ± 0.1) follow proper food safety practices. Results demonstrated the food safety curriculum was used successfully to improve food safety knowledge. Food Safety Practices Survey results indicated that the majority of food recovery agency personnel and staff were already using proper food safety practices in their agency or at home. In addition, the results from the Food Safety Practices Delayed Survey showed the participants retained the knowledge from the food safety training and a majority were “always” following proper food safety practices.

Background: Consumers’ knowledge on food safety and related practices play central role in reducing foodborne diseases, which represents significant concerns to public health.&#x0D; Objectives: To evaluate rural and urban household consumers knowledge of food safety and related practices in Ogun state, Nigeria. Also, awareness of foodborne illnesses, and association between respondents’ demographic characteristics and food safety knowledge were investigated.&#x0D; Methods: A crossectional study, which involved a questionnaire based interview of a group of 120 volunteers from four different local government areas (LGA) in Ogun State was conducted. Pearson chi-square analysis was used to test the association between consumers’ demographic parameters and knowledge of food safety.&#x0D; Results: Overall, eighteen (15.8%, 95% Cl, 10.0 – 23.7) male, and ninety-six (82.2%, 95% Cl, 76.3 – 89.9) female within the age range 16 – 60 years took part in the study. Our data showed that there was poor knowledge regarding food safety practices and food borne illnesses among rural and urban consumers surveyed. However, there was a significant difference in the awareness of rural and urban household consumers to foodborne illnesses and associated complications, (p &lt;0.05). Also, Respondents’ marital status were significantly associated with knowledge of food safety (p &lt;0.000).&#x0D; Conclusion: Poor consumer knowledge of food safety, and food related illnesses were reported, informing the urgent need to improve on food safety education such as food handling, preparation, storage and general hygiene practices in homes in Nigeria.

This study examines food safety knowledge and practices of food service staff in Al Madinah hospitals, Saudi Arabia. A total of 163 food service staff participated voluntarily from 10 hospitals across the city of Al Madinah. The participants completed a questionnaire composed of three parts: General characteristics, food safety knowledge, and food safety practices. Results showed that respondents generally had good food safety knowledge with the highest pass rate of 77.9% for knowledge of cross contamination followed by 52.8% for knowledge of food poisoning, and 49.7% of knowledge of food storage. Food safety practices were also strongly observed in the hospitals with a pass rate of 92.6%. Food safety knowledge among the hospital food service staff varied with the level of education, age, and having received food hygiene/safety practices, training while food safety practices had a significant association with the level of education and food hygiene/safety practices training of the staff. Spearman rho coefficient results showed that there was a significant linear relationship between food safety practice and food safety knowledge, and that food safety knowledge significantly predicts food safety practices. This research revealed the importance of education and consistent training of food service staff in improving knowledge and thereby better and safe food handling practices, which could contribute to apply food safety in the hospitals.

Food safety is critical for public health and economic development. The hospitality industry offers a variety of food services, led by food handlers with diverse background. The aim of this paper is to evaluate food safety knowledge and practices among food handlers in the Ghanaian hospitality sectors, with the purpose of informing public policy and improving food safety. A cross-sectional survey study was conducted between February and May 2019. Data were obtained from food handlers working in the Ghanaian hospitality industry (N = 306). The findings of the study indicate that most (52.9%) respondents who work in restaurants had knowledge about food safety principles. Lack of training and education was identified by 63.1% of the respondents as a major barrier to food safety. Interestingly, 75.8% of the respondents indicated that food safety practice is not the responsibility of the kitchen staff only. Diarrhea (35.95%), cholera (35.62%), and typhoid (27.42%) were identified as major diseases associated with improper handling of food. Only 65.69% of the respondents undergo annual medical screening at their workplaces. There is correlation between food safety practice and variables such as marital status, type of residence, age, and education level. Educational campaigns coupled with strict law enforcement should be put in place to ensure that food safety rules and guideline are effectively implemented in the hospitality food industry. Training programs should be organized for food vendors and other stakeholders in the food industry as well. Finally, there should be proactive supervision by local government officials to ensure that good sanitation and hygienic conditions are maintained within the food sectors.

This survey assessed street food vendors' food safety knowledge, attitudes, and practices in Rizal Boulevard, Dumaguete City. This study used quantitative research utilizing survey methodology. The researchers used purposive sampling to select 50 vendors as the study's respondents based on their location and street food sales. Findings revealed that most street food vendors were females between 41 and 50, and married. The street food vendors received food safety training and had been in the street food vending business for several years. Despite variations in socio-demographic factors, the respondents displayed an extremely knowledgeable level of food safety knowledge and exhibited a positive attitude towards food safety. However, their adherence to food safety practices in their operations was consistent. For challenges, poor food safety practices were noted in water use, lack of access to safe water, unregulated street vending practices, inadequate waste disposal, and the need for proper facilities. The study emphasized the moderate positive correlation between food safety knowledge and adherence to food safety practices. Findings suggest that higher levels of food safety knowledge, strong positive attitudes, and better practices contribute to better handling challenges in the street food vending sector. To enhance street food vendors' food safety knowledge and practices, several interventions are put forward to support and achieve comprehensive food safety training programs that address the identified gaps. Initiatives could focus on providing accessible and practical training, providing access to safe water and proper waste disposal facilities, and creating awareness about safe food vending practices. Further, collaboration and engagement of relevant stakeholders are essential to create a supportive environment that enables street food vendors to enhance their food safety knowledge, attitudes, and practices. By improving food safety standards, street food can be improved, ensuring the well-being of both vendors and customers.

Owning pets offers various potential health benefits; however, it can be associated with gastrointestinal illnesses due to poor food safety knowledge and practices. This study aimed to evaluate the level of food safety knowledge and practices among pet owners in Lebanon, exploring the association between their knowledge/practices and socio-demographic characteristics. The participants included 300 pet owners, representing various genders, ages, educational levels, educational backgrounds, and incomes. They completed a questionnaire of 72 food handling practices and knowledge questions related to preparation, cross-contamination, storage and hygiene. In parallel, 300 non-pet owners with comparable sociodemographic characteristics to pet owners (control group) completed the questionnaire. On average, food safety knowledge scores were 62.1 ± 14.9% and 58.7 ± 15.5% among pet and non-pet owners, respectively, and the difference was significant (p = 0.05). On the other hand, mean food safety practice scores were 41.3 ± 14.8% and 40.4 ± 15.3% among pet and non-pet owners, respectively, and the difference was not significant (p = 0.41). In the food safety knowledge part, non-pet owners who were young, high income, university graduate, and from health-related majors scored significantly (p < 0.05) higher, while among pet-owners, only participants with a university degree and from health-related majors scored significantly (p < 0.05) higher, in terms of knowledge. On the other hand, In the food safety practices part, non-pet owners who were young, high income, and university graduates scored significantly (p < 0.05) higher, while among pet-owners, only young and high-income participants scored significantly (p < 0.05) higher. These results highlight the need for ongoing educational initiatives to improve food safety practices among both pet owners in Lebanon. The study suggests that targeted educational programs should be developed, considering specific socio-demographic characteristics, to enhance overall food safety awareness and practices among the population.

Annually, millions of the people suffer from foodborne diseases which are mainly associated with poor food handling practices. The poor food safety knowledge and practices increase the risk of food contamination and foodborne diseases. The aim of this study was to evaluate the relationship between demographic attributes and food safety knowledge, attitudes, and practices (KAP) of food handlers (chefs and servers) working in small-scale restaurants, hotels and eateries in Lahore, Pakistan. A structured questionnaire including questions related to demographic characteristics and food safety KAP attributes of food handlers (n = 202) was used to collect the responses. The responses of food handlers were statistically analyzed using Spearman Correlation and Chi-Square tests. The results showed that a large proportion of food handlers had good attitudes towards food safety and followed good food safety practices (FSP) but had poor food safety knowledge (FSK). Demographic characteristics of food handlers i.e. level of education, professional category, current job tenure, and total food service industry experience were significantly (p < 0.05) associated with FSK, FSA, and FSP. FSK was found to be moderate to strongly correlated with FSP of food handlers (rs = 0.675), whereas FSA was found to be strongly correlated with FSP (rs = 0.733). The study highlighted the importance and impact of food safety knowledge on food safety practices and overall perspective of food handlers working in restaurants.

Foodborne illnesses result from inadequate food handling practices, but prevention is possible through implementing food safety principles by handlers and consumers. This paper presents an overview of food safety knowledge and practices among food handlers and consumers in the Gulf countries, identifies factors affecting knowledge and practice, and offers recommendations for promoting food safety among handlers and consumers. A literature search was conducted using an integrative review method. Various combinations of the following descriptors were used: (food safety, food hygiene), (knowledge, practice), and (Saudi Arabia, Qatar, UAE, Bahrain, Oman, and Kuwait). Out of 164 studies screened, 37 met the eligibility criteria. Food handler studies reported insufficient food safety knowledge, with poor translation of existing knowledge into practice. Consumer studies showed varying levels of food safety knowledge, and the translation of existing knowledge into practice was also found to be inconsistent. Training and educational level were the primary factors positively affecting food safety knowledge and practices. Overall, significant gaps in knowledge and practices were identified among food handlers and consumers in the Gulf. These gaps require urgent attention from the Gulf regulatory bodies to develop targeted food safety training and education programs to enhance awareness and implementation of food safety principles.

The aim of this study was to assess food safety education using school book covers and videos to Public Elementary School PES students in Cimahi City, West Java, Indonesia to order to improve knowledge, attitude, and practice of street food safety. We used quasy experiment with pretest−posttest control group design. We selected the intervention group from four public elementary schools in South Cimahi City where food poisoning had occurred, and the control group from four public elementary schools in North Cimahi City by simple random sampling. Samples consisted of 224 students; 112 as control and 112 as intervention group. This study was conducted for six months, in which the food safety education regarding street food safety used diffferent book covers for ten subject note books and videos. The book covers which consisted of materials on bacteriological and chemical food safety were explained once a week within 50−60 minutes duration. The videos regarding street food safety were given for 3 (three) times within 6 months. Before food safety education, there was no significant difference in knowledge, attitude, and practice (p&gt;0.05) between the control and intervention groups. After six month food safety education, knowledge, attitude, and practice significantly improved (p&lt;0.05) in intervention group compared to control group. Within intervention group, knowledge was improved from 5.4% (pre intervention) to 91.1% (post intervention), attitude from 69.6% (pre intervention) to 97.3% (post intervention), and practice from 21.4% (pre intervention) to 59.8% (post intervention). This study provides evidence that food safety education using book covers and videos to the elementary students for six months improved their knowledge, attitude, and practice of street food safety.
