Influence of educational actions on transitioning of food safety culture in a food service context: Part 2 - Effectiveness of educational actions in a longitudinal study

A Comprehensive Review of Food Safety Culture in the Food Industry: Leadership, Organizational Commitment, and Multicultural Dynamics

Food safety culture (FSC) has transitioned from a narrow compliance-based concept to a comprehensive organisational value that is essential for ensuring food safety. This review explores the pivotal roles of leadership, organisational commitment, and cultural diversity in shaping an effective FSC. It highlights how leadership style, particularly transformational leadership, can enhance employee engagement and foster a proactive safety culture. Additionally, the impact of national and organisational cultures on FSC is analysed, emphasising the challenges posed by a multicultural workforce in standardising food safety practices. This article also provides a comparative analysis of FSC across various sectors, such as meat and dairy processing, identifying sector-specific challenges and best practices. In particular, high-risk sectors tend to exhibit a stronger FSC due to regulatory pressure, while other sectors struggle with issues like communication and employee ownership. The importance of integrating behavioural training with cultural considerations is underscored as a key strategy for sustaining a positive FSC. For maintaining a strong FSC, tailored approaches, which account for cultural and operational differences, are necessary for improving food safety outcomes. This comprehensive analysis provides valuable insights for industry professionals and policymakers, offering a foundation for future research and the development of more effective food safety management practices.

Observation of Food Handlers' Hand Hygiene Behavior During Production at a Sandwich-making Factory

Effective hand hygiene is essential during food production to reduce the risk of microbiological contamination. Improper hand hygiene by food handlers can be a major contributing factor in the spread of foodborne illnesses. Self-reported behavior does not equate to actual behavior as it has the limitation of biases. Therefore, observational data are more effective at assessing the actual behavior of food handlers. Covert observation utilizing closed-circuit television (CCTV) cameras can yield reliable data. This study utilized covert observation to assess hand hygiene compliance from CCTV footage of food handlers in a sandwich-making facility. An electronic observation checklist, based upon the company's hand-hygiene protocol, was used to capture observed hand hygiene practices. A total of 588 occasions that required hand hygiene practices by food handlers (n = 12) were observed during the production of ready-to-eat (RTE) sandwiches over 16 h during two shifts. Food handlers did not wash their hands on 32% of occasions which required food hygiene practices. Of those occasions where there was an attempt to implement hand hygiene practices (n = 401), only 1% of behaviors were compliant with the company hand hygiene protocol. Observations indicated that 95% of attempts did not adhere to the recommended handwashing duration (≥20 s). Soap was not used in 4% of attempts, and hands were not wetted prior to applying soap in 16% of attempts. Additionally, 62% of attempts did not use hand sanitizer after handwashing and drying. Food handlers were observed attempting hand hygiene practices significantly more frequently (p < 0.001) when entering (89% of occasions) than exiting (8% of occasions) the production area. Findings indicate that appropriate interventions are needed to improve hand hygiene compliance of food handlers to ensure food is produced safely within the food manufacturing sector.

A multi-case study exploring the effect of interventions on food safety culture maturity

In each food business, a food safety culture (FSC) with a certain maturity level prevails. Previous research has demonstrated that the maturity level of the prevailing FSC can be assessed, but empirical proof of FSC maturity improvement remains limited especially in food processing companies. This study aimed to zoom in on the food safety culture improvement trajectory of four food processing case studies, focusing on human-organizational dimensions of food safety culture. First, a pre-assessment of the maturity of the prevailing food safety culture was executed in each case company (assessment time 1) by application of a validated mixed-methods methodology which includes three different tools (the food safety climate questionnaire, management interview, and on-site evidence collection visits). Based on this pre-assessment, underdeveloped dimensions or gaps in the prevailing food safety culture were identified to find improvement needs. In each of the 4 included distinct case companies, an intervention was implemented. In the first case company, case 1, a food safety key performance indicator (KPI) system was implemented as the intervention, with shared monitoring and shared responsibilities for KPI improvement. Coincidentally, case company 2 and case company 4 selected the same intervention. Case 2, as well as case 4, decided to implement structured group discussions with operators to collect input for collaborative action point selection, aiming for their active involvement in food safety. In case 3, a food safety culture check system was implemented for systematic reward and recognition. After intervention implementation, the post-assessment was conducted (assessment time 2), applying the exact same methodology as the pre-assessment. To investigate the extent of improvement, comparison of the pre- and post-assessment in each of the four cases was first done descriptively by comparing the means. Next, data collected via the food safety climate questionnaire was compared statistically via Mann-Whitney U tests. Analyses showed a substantial objective and subjective (employees' perceptions) improvement of the targeted food safety culture gaps in companies 1 and 2, demonstrating that food safety culture improvement was achievable through a science-based and cocreated intervention process and implementation plan compliance. In cases 3 and 4, marginal improvements and unchanged scores were revealed. Comparison of cases' trajectory characteristics and resulting success rates demonstrated that senior management involvement was essential for interventional success, as well as implementing culture interventions on an organizational or group level, instead of only including selected employees.

Interventions in food business organisations to improve food safety culture: a rapid evidence assessment

The European Commission recently adopted Commission Regulation (EU) 2021/382 requiring food businesses to establish and provide evidence of a food safety culture (FSC). FSC incorporates management systems, risk perceptions, leadership, communication, environment and commitment to ensure food safety. This review (n = 20) investigates food safety interventions in food businesses to identify effective strategies to improve food safety practices and FSC, and to provide recommendations for improving FSC. Results found that most interventions focused on knowledge training and that workplace practical demonstrations produced the best outcomes. Similar training topics were used evidencing the existence of common training needs. Frequent training over longer time periods was most successful for behavioral change, yet no sustained behavioral change was reported, indicating that single knowledge-based interventions are insufficient, reinforcing repeated experiential learning to be incorporated into training. We suggest that FSC training should focus on FSC more broadly, rather than solely on knowledge training, and that management leadership skills in particular are important to ensure sustained positive change. This study contributes to knowledge by providing a summative overview of food safety interventions and how components of these may be used to enhance FSC in food businesses.

Certified Food Safety Management Systems Assessed through the Lenses of Food Safety Culture and Locus of Control: A Pilot Study

The approach to ensure food safety (FS) has evolved, including the concept of FS culture, which has been shaped by both the legislation and the scientific literature. In this study, two companies that produce foods associated with potential risks of cross-contamination (gluten-free foods and frozen pastry, respectively) and are certified according to international voluntary FS standards, such as the British Retail Council Global Standard (BRC) and the International Featured Standards Food Version (IFS), were investigated to assess: (a) if the assessment of FS culture's pillars can uncover unexpected critical areas; (b) if the scores of the FS culture's pillars are related to personal traits, namely, age, seniority in the company and locus of control orientation, i.e., the beliefs that an event is the result of external factors (luck, destiny or superior beings), or the result of internal factors (human behavior). Questionnaires for the survey and the scoring system applied were selected from the literature. Results showed that all food handlers had an optimistic bias, which paradoxically could be the consequence of the rigorous application of hygienic procedures. The younger food handlers had significantly (p < 0.05) lower commitment than the older ones. Moreover, the segment of food handlers having an external locus orientation demonstrated weaker normative beliefs than those having an internal locus of control orientation. Results showed that the FS culture survey, which is related to the shared FS culture, could disclose unknown weakness in third-party certified companies, even if the well implemented principles of voluntary FS standards are aligned with the FS-culture pillars. Moreover, the segmentation of food handlers according to their age and the locus of control assessment could provide additional information on the individual orientation toward FS behavior. Hence these tools could assist the leaders in the management of the dynamic nature of human capital.

Are Socio-Economic Indicators Associated with Food Safety in Public Schools? A Study in Sergipe State, Brazil

The Brazilian National School Feeding Programme aims to ensure food security and the right to food for public school students. To protect these fundamental rights, a comprehensive approach is needed that includes ensuring food safety. Recognising that low socio-economic conditions, inadequate food safety and child vulnerability can pose a cumulative burden on child development, this study examined food safety in public schools in Sergipe, Brazil, in the context of local socio-economic indicators. All state public schools in Sergipe (n = 314) were included. Food safety and socio-economic data were analysed using secondary sources and geographical maps. The cluster analysis identified two different groups of schools based on socio-economic indicators. While most schools presented regular foodborne illness risks, food production and temperature control had particularly high levels of non-compliance. Schools in areas with higher socio-economic indicators (Cluster 2) had better overall food safety scores (p < 0.001) compared to schools in areas with lower socio-economic indicators (Cluster 1). Cluster 1 schools also had a higher FBI risk when analysing temperature-controlled equipment violations (p = 0.001), food handlers (p = 0.005) and process and production (p = 0.004), which emerged as critical areas. These results emphasise the urgent need for targeted interventions to improve food safety in schools located in areas with lower socio-economic conditions.

Towards a risk-based food safety management system in the fresh produce supply chain in Da Nang, Viet Nam

Food safety has emerged as a paramount concern for both Vietnamese consumers and the government. However, limited data are available on food safety management systems in Viet Nam. This study identified significant gaps in good agricultural and hygienic practices along the fresh produce chain (farmers and traditional wholesalers/market sellers) in the region of Da Nang, Viet Nam. This was achieved through a survey on good agricultural and hygienic practices for farmers (n = 100) and sellers (n = 100), which researchers further supplemented by microbiological analysis for E. coli, Salmonella spp., and Listeria monocytogenes on leafy greens, water in contact with produce and contact surfaces (hands). The results indicated that 86.0 % of farmers and 54.0 % of sellers received food safety training in the last 3 years; and women dominated both vegetable cultivation but also trading. Farm-level deficiencies included inadequate handwashing practices, lack of documentation for manure application schedules, improper washing and drying of harvest tools, failure to keep containers elevated off the ground, improper storage of vegetables, and inadequate covering of containers, with respectively 34.0 %, 30.3 %, 12.1 %, 41.7 % and 7.9 % of farmers executing the practice as prescribed by the WHO/FAO '5 keys of growing safer fruits and vegetables'. As for sellers, the most dominant gaps (<50.0 % compliance) were the way of handwashing and the practice of keeping containers elevated off the ground before, during, and after harvesting. The microbiological analysis confirmed that, in a total of 36 fresh produce samples including mustard greens, cucumber, lettuce, and crown daisy, the number of samples positive for E. coli, Salmonella spp., and L. monocytogenes were 12, 2, and 10 respectively. Samples of hands and the irrigation water showed high contamination with E. coli. Based on identified gaps, risk communication tools were developed and distributed amongst farmers, sellers, and Da Nang food safety management authority (governmental organisation performing inspections in the traditional food markets). As intervention, two farmers and two sellers were trained in safe agricultural practices for the cultivation of fresh vegetables (managerial intervention) and instructed to use tap water as irrigation water instead of uncontrolled surface water (technological intervention). A post-assessment was conducted, including redoing the survey on good practices and microbiological analysis. The outcome of these interventions showed positive results in terms of good agricultural and hygienic practices resulting in improved hygiene levels and safety of the fresh produce. The findings from this research have the potential to provide a model for the development of a science-based risk management strategy in alternative food chains or geographic areas in emerging countries.

The Relationship between Food Safety Culture Maturity and Cost of Quality: An Empirical Pilot Study in the Food Industry

In the food industry, a mature food safety culture (FSC) is linked to better food safety performance. However, the relationship between FSC maturity and key economical performance indicators, such as cost allocation, remains unexplored. This research is the first pilot study to empirically explore the association between FSC maturity and cost of quality (CoQ). A CoQ survey was developed and pretested. CoQ data were collected through collaboration with company management. FSC maturity was assessed through a validated mixed-method assessment (diagnostic instrument, questionnaires, and interviews). A convenience sample of five food processing companies was assembled and subjected to FSC and CoQ assessment. Results revealed that monitoring CoQ is not yet standard practice in the food industry: three out of five companies were unable to specify all failure costs. For prevention and appraisal costs, results showed descriptively and statistically that when these costs are higher, FSC is more mature. Considering the theoretical context of the research (CoQ models and available literature), these results present the first empirical evidence to substantiate that FSC could replace product/service quality in CoQ models. Findings justify the push for a shift in perception, from considering FSC as a task on the list of resource demanding activities toward a narrative in which FSC contributes to financial health.

Food safety culture in food companies amid the Lebanese economic crisis and the Covid-19 pandemic

The challenges to food safety in Lebanon are many and have worsened due to the Covid-19 pandemic and the Lebanese economic crisis. Against a backdrop of loosely enforced food laws and regulations, a cross-sectional study was carried out in 23 Lebanese food companies on 204 participants using a validated online food safety culture self-assessment tool consisting of 28 indicators. Food safety motivation, burnout/job stress and conscientiousness and their impact on food safety culture were also investigated. Overall, the perceived food safety culture was "good" with a mean value of 119.1 over 140 (equivalent to 4.3/5). A young workforce, the female gender, a science background, and a university degree were associated with a higher food safety culture. The food safety culture score was also perceived higher among participants who attended food safety trainings, and among those working at the managerial level and in the quality department. In addition, the results showed that the food safety culture was significantly better in companies exporting their goods than companies with no international market exposure (121.6 vs 118.1). Moreover, Food safety motivation (mean score 4.1/5) and conscientiousness (3.5/5) were moderately associated with a positive food safety culture. However, the low burnout/job stress scores (2.8/5) may exhibit a negative impact on the food safety culture and could be related to several consequences caused by the Lebanese economic crisis and the Covid-19 pandemic. Further studies are to be conducted to understand better the causal effects relationship.

Food safety culture in food companies: evaluation of the perception of food safety culture in three Tuscan food companies

The Commission Regulation (EU) No. 2021/382 (European Commission, 2021), amending the Regulation (EC) No. 852/2004 (European Commission, 2004), introduced the obligation for companies to establish and maintain a food safety culture (FSC). The methodology to evaluate, implement, and enhance the level of FSC is up to the individual companies. This study aimed to investigate the perception of FSC among the employees of 3 Tuscan medium-sized enterprises in the food sector, producing cured meat (A), dairy products (B), and frozen fish products (C). The survey was conducted through the development and administration of a questionnaire based on a 5 points Likert scale, referring to different aspects of FSC, organized in 6 sections with 5-6 statements each and subjected to a percentage of employees between 76 and 85%, classified also by the length of service (≤3 and >3 years). For all the companies, the minimum median and mode value for scores obtained by the different sections was 4, and the minimum median and mode value for the single statement was 3 (A, B; except for a bimodal value 2-4) and 4 (C). The section awareness and perception of risk showed the highest mean scores in all companies. As for the length of service, senior employees gave lower scores than junior ones in all sections in B and 3 sections in C. Overall, the results of the questionnaires showed a good perception of FSC, even though it was possible to identify some partial weaknesses.

Improving Food Safety Culture in Nigeria: A Review of Practical Issues

As a developing nation and the most populous nation in Africa, Nigeria has enormous challenges connected with food safety culture. To produce and provide safe, secure and nutritious food, consumers and food businesses must abide by a set of shared values known as food safety culture. In Nigeria, food safety culture is a complex subject due to Nigeria’s heterogeneous and diverse nature, as demonstrated by its over 250 ethnic groups. As Nigeria becomes more urbanized and incomes continue to fluctuate at robust rates, few Nigerians are conscious of food safety issues. In addition, oversight from government regulators around food safety require improvement. Public engagement in food safety issues has not witnessed a promising trajectory in recent years. In this article, we provide a review of the food safety culture in Nigeria and its role and influence on various cases of food safety issues in Nigeria. Of interest to this paper are studies exploring consumer and food handler perceptions and behavior regarding food safety. In addition, keen attention is devoted to areas that are in need of additional research to help address practical and on-the-ground challenges associated with Nigeria’s food safety practices. This article suggests that improving food safety culture in Nigeria requires both applying the best management and communication approaches in different regions and understanding the local food safety practices.
