Evaluation of food safety knowledge and microbial status of food contact surfaces in schools

Determinants of food safety knowledge and practices among food handlers in Bangladesh: An institution-based cross-sectional study

The engagement of a large number of people in big-scale cooking raises the danger of food contamination due to incorrect handling, whether deliberate or unintentional. Contamination during large-scale production poses a serious hazard to consumer health and has significant financial implications for a nation. This study aimed to investigate the food safety knowledge and practices of institutional food handlers in Bangladesh, considering the growing concern surrounding this issue and the lack of available information on foodborne illnesses related to institutions. In addition, the study aimed to determine the factors influencing both knowledge and practices. A cross-sectional study was conducted from June to September 2022, involving 408 institutional food handlers. The sample size was determined using Cochran's formula, and data was collected through purposive sampling. The participants were interviewed in person and completed a pilot-tested questionnaire. A multiple linear regression analysis was conducted to determine the factors related to food safety knowledge and practices. The majority of participants were female (71.3%) and aged between 26 and 35 (mean age 34.53 ± 9.06 years). They were most knowledgeable about hand hygiene and food separation but lacked knowledge about foodborne pathogens and food storage. Thawing food at room temperature was the most inappropriate practice (86%). The mean scores for knowledge and practice were found to be 16.11 ± 2.76 on a 26-point scale (61%), and 9.59 ± 2.07 on a 15-point scale (64%), respectively. Rural food handlers, those with higher education, working more than 10 h per day, and being familiar with HACCP, had higher knowledge. Food handlers aged 18 to 25, with higher income, working in private institutions, having food safety authority knowledge, actively engaging in food safety training, working more than 10 h per day, and having a positive health perception, had better food safety practices.The results of this study reinforce the notion that institutional food handlers would benefit from enhanced exposure to food safety interventions, active participation in training sessions, and strict adherence to food hygiene regulations in their food handling knowledge and practices.

Assessment of prerequisite programs implementation at food packaging manufacturing companies and hygiene status of food packaging in a developing country: Cross-sectional study

Food packaging has a critical role in all food types and along the food chain from product preservation to transportation, distribution, storage, retailing, and end-use. However, it can become a source of contamination and transfer of microorganisms to the packed food when its hygienic status is not well maintained. The aim of this study was to evaluate the Prerequisite programs (PRPs) implementation in 5 food packaging companies across Mount Lebanon through on-site inspections and to assess the compliance of contact surfaces, employee hands and packaging materials to microbiological specifications. Following on-site inspection, none of the companies achieved a full total score of 100% and scores ranged from 25 to 62%. Regarding the assessment of hygienic status of contact surfaces, non-conforming results (acceptable limit ≤0.6 log colony forming units (CFU)/cm2) were observed in 50% (5/10) of the surfaces for total viable count (TVC). For the employee hands, none of the hand swab samples (10/10) was conforming for TVC that was present in all samples above the acceptable limit. Highest and lowest reported values were 4.4 and 1.7 log CFU/hands respectively. For packaging samples collected during on-site inspections, TVC and yeasts and molds were detected in 20% (2/10) of the samples. However, the samples collected from the retail market, had higher contamination rates of 95% (19/20) and 65% (13/20) for TVC and yeasts and molds, respectively. As for Enterobacteriaceae, it was not detected in all tested contact surfaces, employees' hands, and packaging samples. PRPs assessment and related verification activities showed the need for companies to strengthen their hygienic programs and highlighted the importance of food safety management systems (FSMS) implementation not only in food companies but also in food packaging companies. Additionally, the effectiveness of PRPs implementation should be assessed on planned routine basis.

Monitoring of Hygiene in Institutional Kitchens in Belgium

ABSTRACT

Microbiological contamination of food during preparation and storage is a risk factor in institutional kitchens. In this Belgian study, hygiene practices in 40 institutional kitchens from four public sectors (10 hospitals, 10 schools, 10 retirement homes, and 10 child care centers) were evaluated to determine whether differences in these practices exist between these sectors. Contamination levels were also analyzed at several critical contact points. A data collection instrument and microbiological analysis of hand contact surfaces, food contact surfaces, and kitchen utensils were used. Hand washing resulted in only a slight reduction in total aerobic bacteria counts (TACs), and all microorganisms evaluated except E. coli were still present at countable levels. Enterobacteriaceae were found on one-third of the cleaned cutting boards. Cleaned work surfaces had the highest average TAC of all cleaned surfaces. Only slight improvements in TACs and Enterobacteriaceae and B. cereus counts were observed between used and cleaned work surfaces. The results from the data collection instrument revealed that child care centers had the lowest hygiene scores, whereas the other three sectors were fairly similar, with hospitals scoring highest. The low hygiene score for the child care centers was verified by comparing the results for cleaned surfaces among the sectors. The average TAC on surfaces was highest for child care centers and lowest for hospitals. Child care centers also had the second highest total mean counts and the highest number of total surface samples positive for Enterobacteriaceae. The highest number of surface samples positive for Staphylococcus aureus was also found in child care centers. This study highlights some areas of concern for hygiene improvement in institutional kitchens, differences between public sectors, and similarities in conclusions about hygiene based on the scores from the survey instrument and the results of the microbiological analyses.

Food allergy and food intolerance knowledge of foodservice workers in Hungarian schools

To provide food for children with food allergy or food intolerances represents an increasingly important role in school catering services. The number of children with food intolerances is growing continuously; therefore, it is necessary to improve the knowledge of foodservice workers, who are responsible for food provision in school catering units in relation with food intolerances, food allergies. The main goal of our research is to assess and analyze the knowledge of food service workers and food handlers on food intolerances and to determine those factors, which may influence their knowledge. Our research was conducted by using paper and pencil questionnaires. The mean of test results was 89,16% while deviation was 12,26%. There were no correlations between the test results and respondents”™ education level, age group and the number of years working in food catering sector, and only partial correlation was detected with the job of the respondents. Based on the answers the food handling techniques of diet foods represented the poorest results. Our findings proved that the knowledge and food handling practice of food handlers regarding food intolerances and the preparation of diet meals should be improved.
