Knowledge and awareness about food safety, foodborne diseases, and microbial hazards: A cross-sectional study among Bangladeshi consumers of street-vended foods

Recent Advances of Food Hazard Detection Based on Artificial Nanochannel Sensors

Food quality and safety are related to the health and safety of people, and food hazards are important influencing factors affecting food safety. It is strongly necessary to develop food safety rapid detection technology to ensure food safety. As a new detection technology, artificial nanochannel-based electrochemical and other methods have the advantages of being real-time, simple, and sensitive and are widely used in the detection of food hazards. In this paper, we review artificial nanochannel sensors as a new detection technology in food safety for different types of food hazards: biological hazards (bacteria, toxins, viruses) and chemical hazards (heavy metals, organic pollutants, food additives). At the same time, we critically discuss the advantages and disadvantages of artificial nanochannel sensor detection, as well as the restrictions and solutions of detection, and finally look forward to the challenges and development prospects of food safety detection technology based on the limitations of artificial nanochannel detection. We expect to provide a theoretical basis and inspiration for the development of rapid real-time detection technology for food hazards and the production of portable detection equipment in the future.

Theoretical and practical aspects of risk communication in food safety: A review study

Currently, food safety hazards have introduced as one of the most important threats to public health worldwide. Considering numerous crises in the field of food safety at global, regional, and national levels, and their impact on the physical and mental health of consumers, it is very vital to evaluate risk communication strategies in each country. Food safety risk communication (FSRC) aims to provide the means for individuals to protect their health from food safety risks and make informed decisions about food risks. The purpose of this study is to present FSRC as one of the key parts of risk analysis, its importance considering the prevalence of food contamination and recent crises related to food. Additionally, the stages of implementation of FSRC are mentioned. In FSRC, it is essential to comply with the principles and prerequisites. There are various strategies for FSRC nowadays. Different platforms for FSRC are rapidly evolving. Choosing and evaluating the appropriate strategy according to the target group, consensus of stakeholders, cooperation and coordination of risk assessors and risk managers have a significant impact in order to improve and implement FSRC.

Food hygiene knowledge and behaviour among domestic food handlers during COVID 19 pandemic in Bangladesh

The COVID-19 pandemic reshaped every aspect of life, including food safety. Understanding food safety behaviour at home is necessary for developing effective strategies to mitigate foodborne disease during and after this pandemic. This study administered a cross-sectional survey among 503 domestic food handlers to examine the food handlers' food safety concerns during the pandemic and pandemic-related knowledge and hygiene behaviour (PRKHB) in Bangladesh. The results found that only 35.8% of respondents in this study were more concerned about food safety because of the COVID-19 pandemic. Although the results found a good PRKHB among 95.8% of urban food handlers, overall, 62% showed a poor level of PRKHB. Only 38.8% reported washing their hands after returning home or preparing meals every time. The regression model found that food safety concerns positively related to the PRKHB, and participants who lived in rural areas had a negative association with the PRKHB. The study also explored sociodemographic variations and significant differences observed between urban and rural areas. Meticulous educational campaigns and targeted messages to the food handlers on food safety risks, food handling practices and hand hygiene are necessary to minimise the foodborne disease burden in this region.

Food neophobia and its association with sociodemographic factors and food preferences among Bangladeshi university students: Evidence from a cross-sectional study

Food neophobia, described as a reluctance to eat and or avoid new food, is a personality trait that affects food choice. Despite its potential influence on an individual's food intake, food neophobia has been poorly investigated in Bangladesh. This cross-sectional study was designed to evaluate food neophobia and its association with sociodemographic factors and food preferences in a sample of Bangladeshi university students. Five hundred students from five public universities completed the structured surveys. Food neophobia was assessed by a 10-item validated food neophobia scale with some minor modifications based on study settings. A multiple linear regression model was used to observe the factors associated with food neophobia. The mean food neophobia score among study participants was 37.45 (SD: 13.39, Range: 13-67). According to the adjusted statistical model, being female (regression coefficient, β = 2.73), having higher monthly family income (β = -6.64), being underweight (β = 4.68), being overweight (β = -4.63), having any food allergy (β = 9.09), and a history of sickness after eating a new food item (β = 5.16) were significantly associated with food neophobia amongst the participants. The participants' liking of various food items such as vegetables were significantly correlated with food neophobia scores. Nutrition education policies and programs are of importance to address the students' food neophobia during their tertiary education so that they maintain lifelong healthy dietary habits and consume a variety of foods to improve their physical health and well-being.

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.

JE, Tareq MA, Begum MR, Chowdhury MFT, Schack T. Assessment of Food Safety Knowledge, Attitudes and Practices of Food Service Staff in Bangladeshi Hospitals: A Cross-Sectional Study

Food safety knowledge, attitudes and practices among hospital food service staff are crucial in the prevention of foodborne disease outbreaks, as hospitalized patients are more vulnerable to potential hazards. This study, therefore, sought to assess the food safety knowledge, attitudes and practices of food service staff in Bangladeshi hospitals. A cross-sectional study was conducted among 191 food service staff from seven different hospitals in Dhaka and Chattogram from October 2021 to March 2022 using pretested questionnaires. Multiple linear regression was used to identify the factors associated with the food safety knowledge, attitudes and practices. The findings showed moderate knowledge but high levels of attitudes and practices of food safety among hospital food handlers. Food safety knowledge was significantly higher among males, participants from private hospitals and participants working in a hospital that had a food service supervisor and dietitian in charge of food service operations. Moreover, participants from private hospitals and participants working in a hospital that had a food service supervisor and dietitian in charge of food service operations had more positive attitudes and better practices regarding food safety. Hospital management should consider these factors for enhancing food handlers’ knowledge and increase training and supervision on food safety practices to reduce foodborne diseases and outbreaks.

The Association Between Bangladeshi Adults' Demographics, Personal Beliefs, and Nutrition Literacy: Evidence From a Cross-Sectional Survey

Background

Poverty and health illiteracy, combined with inappropriate systems to track disease and infection rates, contribute to children-and-mothers' poor adherence to nutrient-rich foods intake in Bangladesh. Although risk factors for child and pregnant women malnutrition have been explored, the relationship between Bangladeshi adults' nutrition literacy and their demographics and personal beliefs remains unknown. The purpose of this study was to examine the association between adults' nutrition literacy, demographics and personal beliefs in a large sample of Bangladeshi adults.

Methods

Four hundred adults from two districts (Dhaka and Chattogram) of Bangladesh participated in a cross-sectional survey. Data were collected by interviews using a structured questionnaire containing the Nutrition Literacy Scale. Multiple linear regression models were employed to analyze associations between nutrition literacy and related factors.

Results

The mean nutrition literacy score was 21.6 (SD: 3.7; range: 11-32) on a scale of 32. Multiple linear regression revealed that being a businessman (β = 1.66, p = 0.013) or private employee (β = 1.08, p = 0.030), having a higher family income (β = 1.17, p = 0.009), and a higher educational level were positively associated with higher nutrition literacy scores compared to their counterparts. Participants who had ever completed a nutrition-related course (β = 4.95, p < 0.001), and who perceived themselves as having a need for accessing nutrition-related information were positively associated with the higher nutrition literacy compared to their counterparts.

Conclusion

Findings from this study suggest the need for an integrated response plan involving educational interventions and accessible dietary plans targeting adult populations to enhance their nutritional literacy.

Food Safety Knowledge and Attitudes: A Cross-Sectional Study among Saudi Consumers from Food Trucks Owned by Productive Families

Food businesses, such as food trucks (FTs) and family producers have grown rapidly and become popular with people in Saudi Arabia. As foodborne diseases are still a public health concern in the country, consumers should be aware of the safety of foods sold by food trucks. Since there is a dearth of literature, this study aimed to assess the knowledge and attitudes of consumers of food from FTs owned by family producers regarding food safety and foodborne disease. A cross-sectional study was conducted among 921 consumers of food from FTs from two cities in the southern region of Saudi Arabia. Data were collected using an online questionnaire from September to November 2021. Finally, multiple linear regression and a logistic regression model were used to identify the predictors of knowledge and attitude regarding food safety and foodborne illness, respectively. Overall, respondents had moderate knowledge and higher positive attitudes regarding food safety and foodborne illness. Respondents’ knowledge about the potential harm and attitudes towards the safety of foods sold by FTs were significantly associated with marital status, education level, and monthly family income. The findings of this study highlight the need to improve the knowledge, awareness, and attitudes of Saudi consumers of food from FTs owned by family producers on food safety and foodborne illness through intervention programs, particularly targeting consumers with lower educational attainments and income status, to control foodborne diseases.
