Assessment of food safety at university food courts using surveys, observations, and microbial testing

A worldwide review of illness outbreaks involving mixed salads/dressings and factors influencing product safety and shelf life

The trends toward healthy living, vegetarianism, and busy schedules have increased salad popularity. Salads are usually consumed raw without any thermal treatment, and therefore, without proper care they can become major vehicles for foodborne illness outbreaks. This review examines the microbial quality of 'dressed' salads which contain two or more vegetables/fruits and salad dressings. The possible sources of ingredient contamination, recorded illnesses/outbreaks, and overall microbial quality observed worldwide, besides the antimicrobial treatments available are discussed in detail. Noroviruses were most frequently implicated in outbreaks. Salad dressings usually play a positive role in influencing microbial quality. However, this depends on several factors like the type of contaminating microorganism, storage temperature, dressing pH and ingredients, plus the type of salad vegetable. Very limited literature exists on antimicrobial treatments that can be used successfully with salad dressings and 'dressed' salads. The challenge with antimicrobial treatments is to find ones sufficiently broad in spectrum, compatible with produce flavour which can be applied at competitive cost. It is evident that renewed emphasis on prevention of produce contamination at the producer, processor, wholesale and retail levels plus enhanced hygiene vigilance at foodservice will have a major impact on reducing the risk of foodborne illnesses from salads.

Knowledge, attitude, and practices toward food safety among students in Bangladesh: A cross-sectional web-based study

Background

Foodborne diseases are a preventable but under-reported public health issue. These illnesses are a public health concern and contribute significantly to healthcare costs. People must understand how their knowledge, attitudes, and practices affect food safety and how they can reduce the risk of foodborne illness. This study aimed at investigating the current situation of knowledge, attitudes, and practices toward food safety among Bangladeshi students and identifying the determinants of having adequate knowledge, favorable attitudes, and good practices.

Methods

The research is based on a cross-sectional anonymous online survey that took place from January 1st to February 15th, 2022. Participants in this survey had to be at least 8th-grade students enrolled in Bangladeshi institutions. Upon description of the study's aim, the questionnaire's concept, assurances regarding respondents' confidentiality, and the study's voluntary nature, informed consent was taken from each participant before starting the survey. Descriptive statistics, Chi-square test, and logistic regression were used to explore the knowledge, attitudes, and practices of students and identify factors affecting them using the statistical software STATA.

Results

A total of 777 students participated in the study, the majority of them were male (63.96%) and aged between 18 and 25 years (60%). Almost half of the respondents were at the undergraduate level and less than half of the participants (45%) lived with their families. Among the participants, around 47% had adequate knowledge, 87% had favorable attitudes, and only 52% had good practices toward food safety. Female students, students having a food safety course/training, and students whose mothers were educated had significantly higher knowledge of food safety. Besides, students at higher education levels, students having a food safety course/training, and students with educated mothers displayed significantly higher odds of possessing favorable attitudes toward food safety. Similarly, female students, having a food safety course/training, students at higher education levels, and students with educated mothers were significantly associated with good practices toward food safety among students.

Conclusion

The study shows that students in Bangladesh lack knowledge of food safety and have poor practices toward food safety. For the student population of Bangladesh, more systematic and targeted food safety education and training are required.

The Construction of Image Reference Points and Text Appeals Information Tailoring in Promoting Diners' Public Environment Maintenance Behavior Intention

The environmental maintenance of public dining spaces significantly impacts urban construction's sustainable and healthy development. This paper studied the influence of image-text information tailoring relationships on behavioral intentions to promote public dining space environment maintenance. We used a two-factor between-subject experimental design, two (image reference points: self vs. others) × two (text appeals: feasibility vs. desirability). We also examined the mediating roles of environmental maintenance attitudes and environmental responsibility perceptions as regards pro-environmental behavioral intentions. The research results showed the following: (1) Among the four image-text information construction methods, the other's image reference point with the desirability text appeal promotes the diners' pro-environmental behavioral intention with optimal effectiveness; and (2) Environmental maintenance attitudes and environmental responsibility perceptions play mediating roles in promoting diners' intention to maintain environmental behavior in the image-text combined information presentation. Environmental responsibility perceptions cannot be mediated alone and must be progressively mediated with environmental maintenance attitudes.

Food Handling Practices for Apple Drying in Home Kitchens in the United States: A Survey

ABSTRACT

Fruit drying has traditionally received little food safety attention in spite of Salmonella outbreaks and recalls involving low-moisture foods. This study was conducted to assess the food safety implications during the home drying process, with dried apples as an example. A cohort of home apple dryers (n = 979) participated in an online survey through Qualtrics XM in May 2021. The results showed that participants' knowledge of safe food handling practices regarding dried fruit was low. On average, participants used only 8 of 18 identified food safety practices during apple drying. The survey revealed inadequate frequency of hand washing during apple preparation, potential points of cross-contamination from kitchen tools, lack of hurdle technology without a pretreatment step, failure to incorporate a thermal kill step during drying, and a lack of objective measurements to ensure that target parameters are attained. Participants mainly pretreated apples for sensory improvement instead of microbial reduction. When presented with some benefits of pretreatment, participants who did not pretreat their apples considered doing so to kill bacteria. The use of safe food handling practices differed within demographic groups. Participants 18 to 39 years old (mean = 7.47; 95% confidence interval [CI] = 7.26, 7.67) and 40 to 59 years old (mean = 7.43; 95% CI = 7.16, 7.70) reported using fewer safe practices than did those >60 years old (mean = 8.49; 95% CI = 8.22, 8.75), and participants who identified as male (mean = 7.38; 95% CI = 7.16, 7.60) reported using fewer safe practices than did those identifying as female (mean = 7.92; 95% CI = 7.74, 8.11). The findings of this study provide food handling data to support the development of more accurate food safety risk assessment models and to guide the development of food safety education for consumers who dehydrate produce in the home.

Establishing a corporate social responsibility implementation model for promoting sustainability in the food sector: a hybrid approach of expert mining and ISM-MICMAC

Corporate social responsibility (CSR) is significantly related to food companies due to its prominent impact and greater dependency on the environment, economy, and society (triple bottom line - TBL). The CSR-related threats and opportunities' scale are shifting from single companies to networks and supply chains of the food sector. In this regard, this study empirically evaluates CSR initiatives by using Interpretive Structural Modeling (ISM) and Matrice d'Impacts Croisés Multiplication Appliqués à un Classement (MICMAC) methodology. So to develop an ISM-MICMAC-based framework, at first, CSR initiatives were chosen from existing literature with experts' advice. Later, MICMAC analysis results showed that "employee trainings and workshops" and "employee welfare and empowerment" are significant CSR initiatives that could help CSR's integration in the food sector of Pakistan, whereas CSR initiatives "community betterment" and "contribution towards economic development" proved least significant in the model. This study recommends that food sector firms should promote employee-based strategies in the firms. Moreover, the empirical findings of this study help to better understand CSR initiatives and their role in the implementation of CSR in the food sector of developing countries.

Kitchen layouts and consumers' food hygiene practices: Ergonomics versus safety

Our paper emphasizes the importance of the kitchen layout in facilitating consumers' food hygiene practices. A significant correlation was found between the sink placement (inside or outside the kitchen) and hygienic practices during food handling based on a survey performed on consumers from ten European countries, indicating that those who had the sink in the kitchen were more likely to perform proper hygiene practices than those who have not. The self-reported practices were supported by observed practices in 64 households from five European countries. The observational study combined with the examination of kitchen layouts revealed that the kitchen work triangle with its apexes represented by the kitchen sink, cooking stove and refrigerator, which is recommended for ergonomic reasons by architects and designers, did not necessarily support food hygiene practices in kitchens. Cross-contamination events were associated with the sink – countertop distances longer than 1 m. Based on this, a new kitchen triangle with its apexes represented by the kitchen sink, working place (usually countertop) and cooking stove, with the distance between the sink and the working place less than 1 m is proposed to be used as norm in kitchen designs for combining ergonomics with safety. This triangle is proposedly named the food safety triangle and is aimed to mitigate the risks of foodborne illnesses by creating an arrangement that facilitates hygiene practices. This study is the first to highlight the importance of implementing the concept of food safety in the kitchen design based on significant correlations between kitchen equipment placement and consumers’ food safety practices.

•

Sink placement in kitchens correlates with self-reported food handling practices.

•

Sink placement is also correlated with observed cross-contamination events.

•

Kitchen layouts based on the work triangle do not support food hygiene practices.

•

A new triangle named food safety triangle is suggested for kitchens' organisation.

•

Sink – countertop distances ≤1 m favour consumers' food hygiene practices.

Survey of New Zealand Poultry Consumers' Handling of Raw Poultry and Food Safety Awareness To Provide Insight into Risk Factors for Campylobacteriosis

ABSTRACT

New Zealand (NZ) has a high rate of reported campylobacteriosis cases. Cross-contamination in home kitchens during poultry handling is considered the main factor in campylobacteriosis transmission. The main aim of this study was to measure NZ consumers' food safety awareness and self-reported food safety practices associated with handling raw poultry. This study will contribute to the existing knowledge to explain the reasons behind the increase of campylobacteriosis incidents. Findings can help inform future consumer education campaigns to help reduce the incidence of campylobacteriosis in NZ. A cross-sectional survey composed of 31 multiple-choice questions was designed, piloted, and used to collect information about the last time consumers purchased and prepared raw poultry at home. A street-intercept survey in public places, such as supermarkets in the Canterbury region, was used to recruit respondents for this study. A descriptive and inferential data analysis was performed, including a one-way analysis of variance test used to compare the mean scored responses of the respondents among different sociodemographics. Overall, 301 valid responses were obtained. Scores representing reported safe food practices ranged between 2 and 19 (maximum 21), with a mean score of 9.83 (standard deviation of 3.50 with a standard error of 0.20). There was some variation in correctly answered questions by respondents for food hygiene (25%), cross-contamination prevention (55%), temperature control and storage practices (49%), and food safety (52%). Approximately 30% of the respondents reported symptoms of a foodborne disease experienced once to four times during the past 12 months. The study identified low adherence to current recommended food safety practices, including safe food storage and temperature control. The findings can be used to inform a communication campaign regarding food safety needs to be designed urgently in NZ to reduce the rate of campylobacteriosis.
