The Food Safety Knowledge, Attitude and Practice of Malaysian Food Truck Vendors during the COVID-19 Pandemic.

Foodborne diseases are one of the greatest public health threats, but they can be prevented by maintaining food safety practices. Although the food safety literature has been awash with studies from various food operations, there is very limited information on food safety in the food truck business. Therefore, this study aims to assess the level of knowledge, attitude, and practices related to food safety among food truck vendors. A cross-sectional study was conducted among 396 Malaysian food truck vendors using convenience sampling. Data was collected during the Recovery Movement Control Order due to the COVID-19 pandemic through a validated self-administered questionnaire and analyzed using SPSS version 25. The findings indicated that food truck vendors generally have fair knowledge (M = 78.8, SD = 9.09), a positive attitude (M = 94.8, SD = 5.95), and good practices (M = 84.7, SD = 6.62) regarding food safety during the COVID-19 pandemic. Hierarchical regression analysis further showed that food truck vendors' level of education and knowledge of food safety are significant predictors of their food safety practices. This study provides an initial understanding of the food safety knowledge, attitude, and practices among food truck vendors and yields important information in promoting the food safety culture.

Evaluation of Aldehydes, Polycyclic Aromatic Hydrocarbons, and PM2.5 Levels in Food Trucks: A Pilot Study.

Background: The food truck industry has rapidly expanded in the United States and kitchen environments can contain harmful contaminants from cooking emissions. The objective of this study was to examine the levels of aldehydes, polycyclic aromatic hydrocarbons (PAHs), and Particulate Matter (PM)2.5 generated from cooking process in food trucks. Methods: Area sampling was performed twice at two participating food trucks during work shifts. Nine aldehydes and eighteeen PAHs were analyzed according to the relevant standard methods while PM2.5 was measured with a real time monitor. Ventilation performance of the food truck exhaust hoods was also investigated using a thermal anemometer. Findings: Formaldehyde was the only aldehyde detected in all samples with a concentration range of 7.16 to 53.68 µg/m3. No PAHs were detected above the limit of quantification. Average PM2.5 concentrations ranged from 0.65 to 7.03 mg/m3. Food Trucks 1 and 2 have an average exhaust flow rate of 211 and 215 L/s per linear meter of hood, respectively. Conclusions/Application to practice: Overall, Food Truck 2 had consistently higher levels of aldehydes and PM2.5 with comparable ventilation performance as Food Truck 1. The higher exposure levels of Food Truck 2 could possibly be attributed to a larger volume of food orders and the heavy duty cooking equipment with an exhaust flow rate below the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) recommendations. Although more investigations need to be performed, the findings could be used to raise awareness of food truck workers and health practitioners to reduce potential exposure risks.

Food Safety Knowledge, Attitudes, and Practices of Brazilian Food Truck Food Handlers.

This study aimed to (i) compare the food safety knowledge, attitudes, and self-reported practices (KAP) and observed food safety practices of food truck (FT) food handlers, (ii) evaluate the microbiological quality of food and water samples collected from these vehicles, and (iii) establish a score classification for the KAP instrument according to the food contamination probability assessment. This study was conducted in three stages with 40 food truck food handlers conveniently sampled in the Federal District, Brazil, through structured interviews, application of an observational checklist for the assessment of handlers' practices and the collection of food and water samples for determination of microbiological quality. FTs that are likely to exhibit food contamination and are at a high risk of foodborne diseases if at least one of the following situations occur: (1) if a food handler scores ≤6 in the knowledge section; (2) if a food handler scores ≤5 in the attitudes section; or (3) if a food handler scores ≤6 in the self-reported practices section. On the other hand, FTs in which handlers score higher than the cutoff points in all the sections are unlikely to exhibit food contamination and are at a low risk of foodborne diseases. The findings of this study are the first step to understand food handlers' point of view and the initial diagnosis to guide educational strategies in the FT sector.

Brazilian Food Truck Consumers' Profile, Choices, Preferences, and Food Safety Importance Perception.

This study aimed to investigate food truck consumers' profile, choices, preferences, and food safety importance perception. We conducted structured interviews with a convenient sample of 133 food truck consumers in the Federal District, Brazil. Most of the participating consumers were married (52%) and female (56%), who had completed at least tertiary school (81%). The interviews revealed that most food truck consumers eat from food trucks once or twice a week (96%), usually near home (74%), and have an average per capita expenditure of approximately US $5 to US $9.99 (70%). Hamburgers and sandwiches are the most popular food among consumers (72%). Consumers indicated that taste (30%) was the most important reason to choose a food truck and that poor vehicle hygiene (30%) was the main point assigned for not opting for a food truck. Food hygiene and vendors' personal hygiene were considered important by consumers when eating from food trucks (78% and 80%, respectively). Considering all food truck consumers interviewed and the questions about food safety importance perception, the minimum score was 1 and the maximum was 2.9, with a mean score of 1.68 (SD = 0.46), indicating a high level of perceived importance. The instrument of food safety importance perception presented a Cronbach's alpha coefficient of 0.73, indicating good internal consistency. No significant differences were observed in the food safety importance perception scores in gender (0.192), marital status (0.418), level of education (0.652) or food safety training (0.166). However, significant differences were found in the food safety importance perception scores for age (0.026) and the presence of children (0.001). The findings of this study indicate that there remains the need for consumers to comprehend their role in the food supply chain. Food safety and food handling practices are of public concern, and strategies are required to prevent foodborne diseases. Future public health interventions aiming to increase consumer knowledge and awareness of food safety should be emphasized.

Food Trucks: Assessment of an Evaluation Instrument Designed for the Prevention of Foodborne Diseases.

This study aimed to validate an evaluation instrument for food trucks (FTs) regarding its internal consistency and to establish a score classification according to the food contamination probability assessment. The instrument was applied in 44 food trucks (convenience sample), along with microbial analysis, in the Federal District, Brazil. After its application, sample collection and statistical analysis, the evaluation instrument was reduced to a 22-item final version. FTs were divided into three groups according to their ready-to-eat foods. Food trucks from Group A (hot and cold sandwiches) presented the highest percentage of contamination. The lowest percentage of contamination was observed in food trucks from Group C (regional and international cuisine). The application of the validated evaluation instrument to the 44 food trucks revealed that none achieved 100% adequacy. The reproducibility analysis exhibited an Intraclass Correlation Coefficient (ICC) value of 0.780 (CI 95%: 0.597; 0.880), indicating good reproducibility of the instrument. The reliability assessment presented a Kuder⁻Richardson Formula 20 (KR-20) value of 0.627 and a Cronbach's alpha coefficient of 0.634, indicating good internal consistency. The proposed classification score was obtained by assigning 1 point for each item with an inadequate response, and the final score may vary between 0 and 20 points. Food trucks with up to 11 points exhibit low probability of contamination and low risk of foodborne diseases, while food trucks scoring 12 or more points exhibit a high probability of contamination and high risk of foodborne diseases. The evaluation instrument will allow effective assessment of the hygienic⁻sanitary practices and conditions of food trucks and potentially ensure consumers' access to safe food.

Planting Seeds to Grow Healthy Children: Strategic Community Partnerships.

More than one third of U.S adults are considered obese, and childhood obesity has more than doubled in the past 30 years. Food security can influence obesity, in particular, within inner cities where access to healthy food is often limited. The use of a mobile food truck program (with refrigeration) was implemented in two large inner cities in Connecticut as part of an initiative aimed at helping low-income families with young children gain access to healthy food and nutrition education. Collaborating with community child care centers was used. The experiences of the families who participated in the program were assessed via focus groups. Main ideas derived from the focus groups were participant satisfaction with money saving suggestions, ideas for how to make healthier choices, and excitement about opportunities to receive foods that they would not normally buy. This innovative mobile food truck program demonstrated the value of strategic community partnerships to influence health.

Who Is Serving Us? Food Safety Rules Compliance Among Brazilian Food Truck Vendors.

The rise of food trucks as an eating out option requires knowledge of this sector. Balancing the reality of the food truck sector with access to safe food should guide actions and public policies to cater to its peculiarities. Therefore, this study aimed to characterize the Brazilian food truck vendors' profile regarding their socioeconomic status and compliance with food safety rules. From the 118 food truck vendors registered in the Brazilian Federal District, 30% (n = 35) participated in the study. We conducted structured interviews from December 2017 to April 2018. We ranked compliance levels according to a five-point Likert scale based on calculated compliance scores. The interviews revealed that food truck vendors were mostly married males, who had completed at least a tertiary education level, and wanted to start up their own businesses. The compliance levels depict good compliance with food safety rules (overall compliance (OC)-score = 0.69, on a 0 to 1 scale). The food trucks assessed in this study distinguished themselves from the street food and food retail sectors due to their operational structure and the complexity of food production processes. Those particular features should be considered to ensure adequate and effective sanitary control and inspections, as well as to reduce the probability of microbial growth and food contamination and the consequent risk of foodborne illnesses.

Development of a Brazilian Food Truck Risk Assessment Instrument.

This study aimed to develop and validate a checklist instrument as a first step for the risk assessment of the hygienic-sanitary practices and conditions of food trucks. We invited sixteen experienced experts in the food safety field to take part in the process. The checklist was designed based on the Codex Alimentarius, Brazilian resolutions Collegiate Board Resolution 216, Brazilian Collegiate Board Resolution 275, Brazilian Federal District Law no. 5.627 and Brazilian Federal District Normative Instruction 11. The preliminary version of the checklist-composed of 29 items (nine sections)-was evaluated by 13 experts. They evaluated the items regarding their importance (content validation) and clarity (semantic evaluation) by the Delphi technique. The criteria for the approval of the content validation (Likert scale from 1 to 5) and semantic evaluation (Likert scale from 0 to 5) processes were as follows: a minimum of 75% agreement among the experts (W-values ≥ 0.75) and a mean grade ≥ 4. We performed the complete validation process in three rounds. The final version of the assessment instrument comprised 39 items, following suggestions from experts to add or subdivide some questions. The checklist can be used to conduct inspections of food trucks by health surveillance auditors, of food truck vendors' decision-making processes and also as a diagnostic tool. The application of this checklist will allow the effective risk assessment of the hygienic-sanitary practices and conditions in food trucks and potentially ensure consumers' access to safe street food.
