The authors review the small but growing literature linking cognitive biases to food safety problems and foodborne illness outbreaks.

The authors conducted a search of peer-reviewed articles utilizing empirical methods published since the year 2000 focusing on food safety or foodborne illnesses/outbreaks and cognitive biases.

The authors find that most research is conducted at the consumer side of the food system, with few studies examining the potential problems that can arise in the production and processing of food. The authors also observe that most research tends to focus on a few cognitive biases.

This is the most comprehensive study to date examining insights from the literature on cognitive biases and the related discipline of behavioral economics to the specific problem of foodborne illness outbreaks and food safety problems.

Unsafe food consumption results in adverse health conditions, foodborne illness and undernutrition among households and communities. The consumption of food contaminated with harmful microorganisms or with harmful pesticide residuals results in adverse health conditions and undernutrition. However, there are a number of challenges to maintaining food safety in the food systems of developing countries, like Nepal, where awareness of food safety is low and research on these issues is lacking.

We conducted an experiment among youth aged between 20 and 26 years in Nepal to assess their food safety awareness and affinity to safer fresh produce choices. In the classroom setting experimentations with and without information nudges conducted among 224 youth participants, participants chose one fresh produce packet among the four. We analyzed results using multinomial and mixed logit models appropriate for discrete choice modeling.

We found that the youth’s perceived higher importance of sustainable food systems and their knowledge levels on microbial contamination and foodborne illnesses play significantly positive roles. The likelihood of choosing microbial safety-labeled fresh produce or both microbial- and chemical safety-labeled fresh produce increased with nudging among those who have some knowledge of microbial contamination and foodborne illnesses – we found that the interaction of nudging and level of knowledge is significantly positive. Youth belonging to higher income classes do not necessarily have a higher affinity to safer fresh produce but with nudging, the higher income class youth have a higher likelihood of choosing safer fresh produce choices.

Youth engagement and their awareness of food safety could be one of the important strategies to potentially develop them as effective promoters, adopters and educators in enhancing food safety in food systems in Nepal. Our predicted premium for food safety attributes points to the potential scope for the emerging market segment or business opportunities augmenting food safety in Nepal.

We examined the factors influencing the safer fresh produce choices among youth in Nepal. We tested whether awareness levels of microbial contamination and foodborne illness and information nudging affect the likelihood of safer fresh produce choice. Then we predicted the willingness to pay (premium) for safety attributes. To the best of our knowledge, none of the previous studies have examined this aspect in Nepal.

This study examined the knowledge, attitudes and practices (KAP) regarding food safety and hygiene among street food vendors (SFVs) in Jordan, along with associated factors.

This study utilized a cross-sectional design and targeted a sample of 405 SFVs in Jordan's two most densely populated cities. Data were collected through in-person interviews using a validated and reliable structured questionnaire. Descriptive analysis and linear regression were conducted using SPSS v.25 software to examine associations and predict outcomes.

The findings reveal that SFVs possess a moderate level of knowledge but exhibit negative attitudes and inadequate practices regarding food safety. Significant associations were identified between age, education level, work experience, marital status, gender and the vendors' KAP. Older SFVs tend to exhibit lower knowledge and attitudes, whereas those with more experience and higher education levels demonstrate better KAP. Marital status and gender also influence knowledge and attitudes.

This study fills a critical gap in the research landscape by comprehensively examining the knowledge, attitudes and practices of street food vendors regarding food safety, with a focus on Jordan. Its findings shed light on the challenges facing the street food vending industry and offer actionable recommendations for enhancing food safety practices. As such, the study's originality and significance lie in its potential to drive positive change within this vital culinary tradition, safeguarding public health and economic livelihoods.

The purpose of this study was to create and validate a food safety survey for older adults.

The survey was designed to measure food handling and consumption behaviors related to high-risk foods. Survey questions were also designed to capture behavioral constructs from the health belief model (HBM). The first administration of the survey was completed by 349 participants, 55 years of age and older. Exploratory factor analysis was used to assess construct validity, and Cronbach’s alpha was used to assess the internal consistency of the subscales generated through factor analysis. Two weeks after the first administration, the survey was completed a second time by 149 participants from the original sample. The intraclass correlation coefficient was used to evaluate test-retest reliability.

Exploratory factor analysis yielded four factors related to the HBM (perceived susceptibility, perceived severity, perceived barriers and cues to action) and three factors related to food handling practices (handling of processed meats, food thermometer use with poultry and washing or rinsing poultry). Inclusion in a factor meant that the related questions measured the same underlying construct. Cronbach’s alpha for these factors ranged from 0.63 to 0.77. Modification of the survey following validation resulted in the development of a 44-question instrument that can be used with older adults.

This survey will next be administered to a representative sample of older adults to assess relationships between HBM constructs and food handling behaviors and is available for use by other researchers.

There are few validated tools that can be used with older adults to evaluate food safety risks.

This study aims to investigate the integration of blockchain technology into the food supply chain within the restaurant industry. It focuses on how blockchain can be applied to enhance transparency and trust in tracking food sources, ultimately impacting customer satisfaction.

A service design workshop (Study 1) and three between-subjects experiments (Studies 2–4) were conducted.

Results indicate that blockchain adoption significantly improves traceability and trust in the food supply chain. This improvement in turn enhances customer satisfaction through perceived improvements in food safety, quality and naturalness. This study also notes that the effects of blockchain technology vary depending on the type of restaurant (casual or fine dining) and its location (tourist destinations or residential areas).

The findings offer practical insights for restaurant owners, technology developers and policymakers. Emphasizing the benefits of blockchain adoption, this study guides decision-making regarding technology investments for enhancing customer service and satisfaction in the hospitality sector.

This research contributes novel insights to the field of technology innovation in the hospitality industry. It extends the understanding of signaling theory by exploring how blockchain technology can serve as a tool for signal transmission in restaurant food supply chains.

This study aimed to investigate whether information from reliable news sources such as medical experts and government officials, along with governmental and individual risk responses, influences consumers’ perceptions of news and intention to seek more information. Additionally, it aimed to explore the relationships between these perceptions and consumers’ intentions to seek information in a food safety risk event.

A survey design methodology was employed. A quasi-experimental approach divided 470 Taiwanese participants into three groups, each exposed to varying online news content about food safety news, designed according to the Internalization-Distribution-Explanation-Action (IDEA) model. This involved different combinations of reliable sources and risk response advice to examine the impact on news comprehension and behaviour intentions.

The results indicated that consumers perceived the news as highly credible when they read it with reliable news sources or risk response advice. Governmental and individual risk response advice significantly impacted consumers’ understanding of news. In addition, perceptions of news credibility and understanding of news can increase individuals’ information-seeking intentions to protect themselves from food safety risks.

This study introduced novel insights into the application of the source credibility theory (SCT) model within Taiwanese food safety incidents, identifying key factors that motivate consumer information-seeking behaviour. It marks an initial attempt to incorporate the IDEA model-based risk communication content into research design, aligning with existing literature while highlighting the critical role of reliable sources in enhancing news credibility and consumer response.

This study aims to examine how customers’ perceptions of the quality and credibility of restaurants’ food safety information influence customers’ information adoption and, consequently, their trust in the restaurant and purchase intention. It also explores the moderating effects of customers’ food safety knowledge and health consciousness.

Participants were asked to read a food safety message from a chain restaurant’s website before taking a self-administered online survey. Using a cross-sectional design, a total of 526 valid responses were collected in the USA through Amazon Mechanical Turk. A two-step approach consisting of a measurement model and a structural equation model was applied to test the direct and indirect effects. Additionally, hierarchical regression models were developed to test the moderating effects.

Results show that perceived information quality significantly affects perceived information credibility and has a significant direct and indirect influence on information adoption. Furthermore, information adoption has a direct positive influence on customers’ trust in the restaurant and an indirect effect on purchase intention (full mediation effect of trust). Finally, the moderation effects of health consciousness and food safety knowledge were supported.

Restaurateurs can apply research findings to increase the likelihood that customers adopt their food safety information and to enhance customers’ trust and, consequently, purchase intention in restaurants.

Reflecting on framing theory and information processing theory, this study examines the ways that customers process restaurants’ food safety information by developing an original conceptual framework with strong empirical data support.

Fresh vegetables contain advantageous phytochemical components, making them one of the most significant sources of nutrition. The threat of harmful bacteria still exists because these vegetables are not heated in restaurants before being consumed. Therefore, this study aimed to evaluate the microbial quality of fresh vegetables in restaurants of different levels.

A total of 499 fresh vegetable samples (from sandwiches and fresh-cut vegetable salads) were collected from 3 different types of food service establishment: 201 from international restaurants (IRs), 210 from national restaurants (NRs), and 88 from cafeterias (CAs). The samples were prepared and inoculated on specific growth media. The aerobic mesophilic bacteria (AMB) Campylobacter spp., Staphylococcus aureus (S. aureus), Enterobacteriaceae, Escherichia coli (E. coli) and yeast and molds were counted, and Listeria monocytogenes, Salmonella spp. and Escherichia coli O157 were detected using specialized medium.

High counts of S. aureus, above 3 log cfu/g, suggested that 71.5% of samples collected from NRs and 77.3% from CA were not accepted, whereas 81.6% of samples collected from IRs were accepted. The low population of E. coli, less than 2 log cfu/g, suggested that 99.0, 97 and 92.0 % of samples collected from IRs, NRs and CA, respectively, were accepted. Listeria monocytogenes and Escherichia coli O157 were absent from every sample. One sample was positive for Salmonella spp. in each of the NR and CA sample groups.

RIs adhere to health and hygiene standards better than NRs and CAs, according to the findings of vegetable contamination tests.

The hygiene factor is always imperative when customers consider a certain restaurant, and the information contained in customer reviews can be an efficient approach to gauge a restaurant's hygiene during gaps in the official inspection. Therefore, the purpose of this study was to investigate whether information obtained from online reviews could predict the upcoming hygiene rating, specifically, evaluating the impact of both qualitative and quantitative content of reviews on the restaurant hygiene rating.

The quantitative research method with big data analytic techniques was applied in this study. In total, 127,656 pieces of data collected from 1,710 restaurants in four major cities in the USA were used in the analysis. Both quantitative factors (i.e. reviewer's numerical rating, days to review, readability, useful/funny/cool) and qualitative factors (i.e. eight emotional dimensions of textual reviews) were analyzed from the online customer reviews and considered in predicting the restaurant's hygiene rating.

Six out of eight emotional dimensions including anger, disgust, fear, sadness, surprise and trust were identified as having significant influences on the restaurant hygiene ratings. While three quantitative variables including days to review, readability and usefulness were identified with significant impacts on the dependent variable of restaurant hygiene rating.

This study opens an avenue for innovative research that establishes a connection between customers' reviews and restaurants' inspection systems. The results allow restaurants to predict an impending hygiene inspection rating upon dynamic assessment of review content and aid in adjusting hygiene measures accordingly.
