3. Results and Discussion
The sustainability of food primary processing enterprises, including those responsible for the initial handling, cleaning, grading, and preservation of raw agricultural products, is strongly shaped by human-related factors, particularly safety culture and pro-quality awareness. These two elements are closely interconnected and play a critical role in ensuring both food safety and long-term organizational performance. In primary processing operations, the risk of contamination, product deterioration and occupational injuries is especially high due to direct contact with raw materials, biological hazards, and variable environmental conditions.
A well-developed safety culture supports consistent compliance with hygiene standards, correct usage of personal protective equipment, and effective implementation of hazard identification and control measures. Research indicates that organizations with a strong safety culture demonstrate higher levels of employee engagement, fewer non-compliances, and improved food safety outcomes, particularly in high-risk processing environments [
9]. Moreover, pro-quality awareness among employees enhances attention to detail, responsibility for process outcomes, and adherence to established procedures, which are essential for maintaining product integrity and traceability throughout the early stages of the food chain.
Continuous training, clear communication of expectations, and visible management commitment are widely recognized as key drivers in strengthening both safety culture and quality-oriented behavior. Leadership involvement signals the importance of food safety and employee well-being, fostering a shared sense of responsibility and accountability at all organizational levels. As emphasized in the literature, integrating safety culture with quality management practices not only contributes to regulatory compliance, but also to sustainable performance, particularly in the social dimension of sustainability by protecting workers, consumers, and organizational reputation [
7].
In the study, the safety culture and awareness of employees from three companies dealing in primary food processing were assessed (
Table 1). The sample presents a moderately balanced gender distribution, with males representing 59.7% and females 40.3% of the workforce.
In terms of departmental structure, the distribution is strongly dominated by the Production department (52.8%), followed by Quality (15.3%) and Maintenance (13.9%).
The analysis of employee tenure indicates that approximately 73.7% of the workforce has less than ten years of professional experience, reflecting a relatively young and expanding employee base. The calculated entropy ratio of 0.81 suggests a moderate level of diversity in seniority. This value indicates that, despite the predominance of less experienced employees, a substantial proportion of longer-tenured staff remains present, contributing to organizational continuity and knowledge retention (
Table 2).
Overall, the workforce structure characterizes a production-oriented organization with a slight predominance of male employees, a strong concentration of staff within core operational departments, and moderate diversity in tenure. Such a profile is typical of a growing industrial or technical enterprise, where the integration of new employees is balanced by the stabilizing influence of experienced personnel.
Figure 1 presents a comparative assessment of departmental knowledge levels (blue circles) relative to the ISO 22000 standard requirements (red squares). The relationship was statistically significant (Chi 2 = 64,9275,
p = 0.0132). The relative proximity of departmental and requirement points reflects the degree of knowledge alignment. The results indicate that R&D and Purchasing demonstrate strong alignment with ISO 22000 principles, suggesting effective awareness and integration of food safety requirements. The Quality department shows moderate-to-high conformity, which aligns with its core responsibility for maintaining quality systems and documentation. The Production department exhibits a moderate level of understanding, implying the need for improved consistency in applying food safety procedures on the operational floor.
By contrast, the Maintenance, HR, and Warehouse departments show a large training gap (
Figure 1). Limited awareness within Maintenance suggests insufficient familiarity with hygiene standards and preventive maintenance protocols, while the low scores observed in HR indicate gaps in understanding competency management and training obligations associated with ISO 22000. The Warehouse department demonstrates the weakest alignment, revealing a critical deficiency in knowledge related to proper handling, storage, and traceability practices.
The results show clear differences in ISO 22000 awareness across departments, indicating that food safety knowledge is not consistently embedded throughout the organization. This uneven distribution of knowledge weakens the effectiveness of the food safety management system and limits its contribution to organizational sustainability. Targeted actions such as focused training for lower-performing departments, improved interdepartmental communication, particularly between Quality and other units, and regular evaluation of staff competence through refresher training and internal audits are therefore required. Addressing these gaps is essential not only for achieving consistent ISO 22000 compliance, but also for supporting sustainable operations by reducing food safety risks, minimizing waste and recalls, and strengthening long-term organizational resilience.
Given the intrinsic relationship between quality and food safety, the respondents were asked to assess whether the implementation of quality management systems within their organization has a significant influence on food safety (
Figure 2). The results indicate that a majority of respondents (69%) perceived quality management systems as having a substantial impact on food safety outcomes. Importantly, no respondents expressed a negative opinion regarding this relationship, underscoring a broadly shared recognition of the role of quality management systems in supporting food safety.
The next question was to indicate whether the quality management systems in the plant were functioning properly. In the opinion of most employees (59%), the systems are functioning properly (
Figure 3). No negative answers were recorded for this question.
Implementing effective quality management systems offers multiple benefits, often improving market competitiveness and positively influencing financial performance. When asked whether sustainable management practices and the implementation of ISO 22000:2018 systems contributed to additional organizational profit (
Figure 4), nearly all respondents (99%) responded yes. This strong consensus highlights that integrating sustainability with food safety standards not only supports business success but also reinforces the company’s long-term resilience by promoting responsible resource use, reducing waste, and meeting stakeholder expectations. Only a small minority (1%) did not perceive these benefits, underscoring the widespread recognition of the value that sustainable food safety management brings to the organization.
A multivariate analysis was performed to evaluate the distribution of departmental knowledge concerning the requirements of the ISO 22000 food safety management system. The analysis extracted two principal dimensions, denoted
Dimension 1 and
Dimension 2, which together explained 76.72% of the total variance in the dataset (
Table 3). Specifically,
Dimension 1 accounted for 43.35% of the variance (eigenvalue = 2.60), while
Dimension 2 explained 33.37% (eigenvalue = 2.00). This cumulative variance indicates that the two-dimensional configuration provides an adequate and reliable summary of the underlying relationships between departmental knowledge levels and the ISO 22000 requirements.
Departments such as R&D, Purchasing, Quality, and Production show strong alignment with ISO 22000, as they are positioned close to the standard’s requirements in the coordination space (
Figure 5). This indicates a high level of food safety knowledge, which is expected given their direct involvement in process design, quality control, and supplier management.
In contrast, Maintenance, Human Resources, and Warehouse are positioned farther from the ISO 22000 requirement cluster, indicating lower awareness and weaker practical application of the standard. Maintenance shows gaps in preventive maintenance and sanitation practices, HR has limited understanding of training and competency requirements, and the Warehouse department demonstrates the greatest deficiencies, particularly in handling, storage, and traceability.
Overall, these patterns reveal uneven implementation of ISO 22000 across departments. The clustering of high-performing departments suggests that food safety knowledge is concentrated in specific functions rather than consistently integrated throughout the organization.
To achieve comprehensive and sustained compliance, targeted capacity-building initiatives should be prioritized for departments exhibiting lower performance, namely Warehouse, Human Resources, and Maintenance. Strengthening interdepartmental communication, particularly between the Quality department and supporting operational units may enhance knowledge exchange and improve the consistency of procedural implementation. Additionally, the adoption of periodic, data-driven evaluations, such as follow-up multivariate analyses and systematic internal audits, is recommended to monitor progress in knowledge alignment and to assess the long-term effectiveness of training and development interventions.
The respondents were also asked about the perceived benefits of implementing sustainable management practices alongside the ISO 22000 food safety management system. The most commonly reported benefit, cited by 81.3% of respondents, was an increase in food safety. This aligns with existing research showing that standardized food safety systems improve hazard identification, control, and prevention throughout the food supply chain. By enhancing food safety, these systems contribute directly to sustainability goals reducing foodborne risks, minimizing waste from contamination or recalls, and promoting consumer health and trust thereby supporting the environmental, economic, and social pillars of sustainable development within the organization [
9]. In addition to improved food safety performance, a substantial proportion of respondents reported positive market-related outcomes. Specifically, 69.3% of respondents perceived an improvement in the company’s ability to meet consumer requirements, while 78.7% indicated increased customer trust. These findings align with prior studies demonstrating that the implementation of recognized certification schemes enhances transparency, credibility, and stakeholder confidence, particularly in sectors characterized by high food safety risk [
10].
Furthermore, 69.3% of respondents noted an improvement in the company’s market image following the adoption of sustainable management and ISO 22000 principles (
Figure 6). This result supports the view that food safety and sustainability certifications function not only as operational tools but also as strategic instruments that strengthen corporate reputation and competitive advantage. As highlighted in the literature, organizations that integrate food safety management systems with broader sustainability objectives are better positioned to respond to regulatory demands, consumer expectations, and social responsibility goals, thereby contributing to long-term organizational sustainability.
Overall, the findings suggest that the implementation of sustainable management and ISO 22000 systems delivers multidimensional benefits, encompassing enhanced food safety performance, improved customer relations, and strengthened market positioning. These outcomes reinforce the role of integrated management systems as a key driver of both operational excellence and sustainable development in the food processing sector.
The analysis evaluated employee awareness across individual organizational departments regarding the potential for improving the company’s financial performance through the implementation of a sustainable management approach (
Figure 6). Employees in the Quality, Production, and Purchasing departments demonstrated the highest levels of awareness of these relationships. This may be attributed to the indicator calculation methodology used to assess the extent to which departmental objectives are achieved.
Figure 7 shows the relationship between ISO 22000 implementation and perceived additional benefits across departments, together with the level of awareness. R&D is positioned farthest to the right, indicating the strongest perception of benefits from ISO 22000 implementation and relatively high awareness. Production, Quality, Purchasing, and Warehouse are clustered near the center of the plot, suggesting moderate awareness and a moderate perception of additional benefits. Quality and Maintenance appear higher on the vertical axis, indicating higher awareness compared with other departments at similar implementation levels. HR is located in the lower-right area of the figure, reflecting lower awareness despite a moderate perception of benefits. Maintenance and Warehouse are positioned further from the main cluster of benefits, indicating weaker alignment between awareness and perceived value. Overall, the spread of departments across the figure indicates variability in both awareness and perceived benefits of ISO 22000 implementation, with departments differing in how strongly they recognize and experience its added value.
In the conducted work, respondents were asked to indicate how frequently product safety should be verified (
Figure 8). The majority (88.9%) stated that food safety verification should occur at the commencement of each new production cycle. Furthermore, 69.4% of respondents indicated that verification should be carried out whenever production changes occur, such as the introduction of new raw materials. In contrast, 31.9% of respondents held the view that product safety verification should only take place in response to customer complaints. A very small proportion of employees (1.3%) responded that such verification activities should only be performed during external audits.
In order for the plant to achieve even greater results, the management of individual departments should motivate its employees to constantly expand knowledge and make every effort to ensure that the employee is fully aware of their role in creating safe food and support it for this purpose. Effective communication between management and employees is also essential. Wajcht and Gola [
3] describe how important communication between the manager and the employee is. The authors point to a very important role of the highest management in motivating their employees. Management should constantly train and share their knowledge with the employees. Skrzypek [
11] also compares the relationship between quality management and knowledge of the organization. Her research has shown that a proven tool for improvement in the indicated areas are quality and knowledge management systems. Although both knowledge and quality are inherently challenging to quantify, they play a fundamental role in organizational functioning and continuous improvement.
The data presented in
Table 4 indicate that employees exhibit a high level of trust in their supervisors. Strong trust is an important aspect of effective management and corporate order, which in turn promotes a positive atmosphere at work and translates into employee involvement. Based on the examination, it can also be suggested that communication between employees and superiors is generally effective, contributing to increased efficiency in daily tasks. Most employees (88%) report feeling motivated by their supervisors, which may enhance their commitment to daily tasks, increase productivity, and strengthen overall job satisfaction. Additionally, more than three-quarters of respondents (77%) indicated that they are consistently informed about company activities, a factor that can foster a sense of belonging, improve understanding of organizational goals, and promote further employee engagement. Moreover, the majority of employees (83%) know who to contact in the event of a problem, suggesting a strong awareness of the organizational structure and established procedures, which facilitates effective problem-solving and may contribute to a calmer, more confident approach to work. To further enhance management practices in this domain, continued emphasis on communication, ongoing training for supervisors in communication and motivational skills, and the implementation of structured recognition programs for employee achievements are recommended. Such measures are likely to strengthen employee engagement and reinforce a culture of accountability and performance.
Analysis of the results presented in
Table 5 suggests that employees are strongly connected to their plants, satisfied with their tasks, and aware of their responsibilities toward the company and its clients. They recognize their role in ensuring the quality and safety of raw materials and products, which not only supports smooth plant operations but also contributes to the long-term sustainability of the organization. By maintaining high standards of product safety and quality, employees help reduce waste, prevent recalls, and protect consumer health—key aspects of environmental and social sustainability.
Within the management system, these factors are crucial for safeguarding the company’s reputation, enhancing stakeholder trust, and supporting sustainable business performance. Employee engagement and motivation can be further strengthened through integration programs, company meetings, and social initiatives, which increase a sense of belonging and foster a sustainable organizational culture. To reinforce employees’ responsibility for sustainable outcomes, targeted training in product quality, safety, and the broader impacts of their daily activities should be conducted. Additionally, recognition of individual contributions to company successes can further motivate employees, aligning personal performance with sustainable organizational goals.
The results of the study confirm that employee seniority influences both knowledge and organizational commitment. Higher levels of knowledge and engagement observed among longer-tenured employees may be linked to increased intrinsic motivation [
12]. However, these findings differ from those of [
13] (2015), which reported that seniority does not significantly affect employee motivation. This inconsistency suggests the need for further research to examine whether contextual factors, such as organizational size or type, moderate the relationship between seniority and employee engagement.
Furthermore, the concept of “quiet knowledge” emphasizes that many skills and competences acquired by employees are not easy to express in words and definitions, but they manifest in their daily and routine activities [
14]. In the context of production plants in which this study was conducted, quiet knowledge can play a key role in maintaining high safety and quality, even when employees are not fully aware of theoretical knowledge about their principles. The literature on food safety management emphasizes that regular training and audits are essential for sustaining hygiene and quality standards [
15]. Improving the training system in plants can not only improve the theoretical understanding of employees, but also strengthen awareness and commitment to striving for continuous improvement of production processes.
This perspective aligns with the classic motivation theories which highlight the important role of financial factors in motivating employees, especially in production industries [
16].
However, it should be emphasized that intangible forms of motivation such as recognition, opportunities for professional development, and supportive workplace relationships also play a critical role in effectively motivating employees. A study conducted in 2015 among randomly selected employees from various enterprises in Slovenia demonstrated that no single factor universally determines employee motivation. Instead, motivation was found to result from different combinations of factors, primarily, though not exclusively, related to personal and interpersonal aspects of professional life. Positive relationships with colleagues and supervisors, access to training and career development opportunities, and well-structured organizational practices were identified as key determinants of favorable working conditions and employee satisfaction [
17].
The positive influence of both material and non-material motivators was further confirmed during the COVID-19 pandemic, when organizations that adopted balanced motivational approaches were better able to sustain employee engagement and performance under crisis conditions [
18]. Collectively, these findings highlight the importance of integrating both tangible and intangible motivational strategies within organizational frameworks in order to enhance employee commitment, performance, and overall organizational effectiveness.
Figure 9 presents the opinions of the respondents on their personal impact on quality management. According to the opinion of 49% of respondents, employees have a personal impact on quality management. Only 5% of respondents had no opinion on this subject.
Each quality system incorporates specific rules that employees must follow to ensure the quality of the final product as well as the safety of both workers and consumers. The respondents were asked whether they believed that employees work in accordance with quality management principles; their views are presented in
Figure 10. Over half of the respondents (52%) indicated that employees adhere to the established rules, while 3% reported having no opinion. Only one respondent stated that such rules are not consistently followed by plant personnel. Overall, these findings suggest a generally positive perception of compliance with quality management principles, although minor gaps in awareness or practice may still be present.
Before the employee begins to perform their duties, they must be properly trained in their position and must become familiar with the individual principles that the plant introduced, including the basic knowledge of the introduced quality management systems. To evaluate the effectiveness of this preparatory training, the respondents were asked whether newly hired employees receive adequate instruction in food safety before beginning work (
Figure 11). The results indicate that an overwhelming majority of respondents (98.6%) affirmed that new employees are thoroughly trained in food safety prior to assuming their duties. These findings underscore the plant’s commitment to ensuring that all personnel are equipped with the necessary knowledge and skills to maintain product safety and compliance with quality standards.
Research conducted by Stobiecka et al. [
19] in a meat plant showed that the state of knowledge of the plant employees was classified as being sufficient. The meat plant had implemented GMP, GHP, HACCP, ISO 22000, and ISO 9000:2015 [
20] systems. The results presented by the authors of the study indicate awareness and understanding of the importance of food safety [
17]. Comparable analyses were conducted by Wajcht et al. [
3]. These authors’ results indicated that the respondent are aware of the reasons for introducing systems in the food industry. The respondents also noticed the benefits of the introduced systems at the plant. This work also raised the issue of available tools on the market that can help improve implemented systems. A number of proposals can be found in the literature. Wiśniewska et al. [
21] proposed food safety culture as a tool to help manage sustainability. According to Costa et al. [
22], it is worth introducing a Japanese management model to the plant.
