The purpose of this study is to outline the results of the empirical testing in the field of halal food supply chain and halal integrity assurance (HIA), as well as to provide a research framework of their relationships.

This study is based on the exploratory research paper using quantitative data collection to empirically experimented with concepts and provide practical solutions for halal industry players to optimize their halal food supply chain integrity assurance.

The findings show the halal supply chain of the food and beverage industry has a significant effect on HIA. The results also suggest the halal industry with a high focus on supply chain business processes and supply chain network structure are expected to have better HIA.

As this study only focuses on the halal industry in Malaysia specifically on food and beverages, its findings cannot be generalized to other categories. Issues of applicability of this study to other countries also need to be considered.

This study addresses the assurance of halal integrity is a crucial element in managing a halal food supply chain in the halal industry. It has empirically identified the important elements to strengthen halal food supply chain integrity assurance in the halal industry.

It is important to manage knowledge, commitment and trust in any halal organization as a catalyst for HIA. This study presents a better understanding of the halal concept application in society.

There is a lack of empirical study on halal food supply chain integrity assurance even though the issue of HIA is widely discussed in the halal industry. Thus, this study has used an industry survey to empirically experimented with concepts and provide practical contributions to enhance halal food supply chain integrity assurance.

Halal integrity assurance is the primary objective of Halal supply chain management. Several halal-related risks are present that have the potential to breach halal integrity. Therefore, this study aims to develop the framework for the assessment of halal-related risk from a supply chain perspective.

Risk related to halal is identified through the combined approach of the systematic literature review and experts’ input. Further, these risks are assessed using the integrated approach of intuitionistic fuzzy number (IFN) and D-number based on their severity score. This integrated approach can handle fuzziness, inconsistency and incomplete information that are present in the expert’s input.

Eighteen significant risks related to halal are identified and grouped into four categories. These risks are further prioritised based on their severity score and classified as “high priority risk” or “low priority risks”. The findings of the study suggests that raw material status, processing methods, the wholesomeness of raw materials and common facilities for halal and non-halal products are more severe risks.

This study only focusses on halal-related risks and does not capture the other types of risks occurring in the supply chain. Risks related to halal supply chain management are not considered in this study. Prioritisation of the risks is based on the expert’s input which can be biased to the experts' background.

The proposed risk assessment framework is beneficial for risk managers to assess the halal related risks and develop their mitigation strategies accordingly. Furthermore, the prioritisation of the risks also assists managers in the optimal utilisation of resources to mitigate high-priority risks.

This study provides significant risks related to halal integrity, therefore helping in a better understanding of the halal supply chain. To the best of the authors' knowledge, this is the first comprehensive study for developing a risk assessment model for the halal supply chain.

Supply chain has long faced a persistent workforce shortage. To help both organizations and the field create environments that are more conducive to employee retention, the authors investigate the outcomes of supply chain employee trust in their supervisor.

Applying person-environment fit theory, the authors evaluate the well-established antecedents to trust in supervisor ability, benevolence and integrity (ABI) relative to person-job (P-J) fit and person-vocation (P-V) fit of US supply chain employees.

Confirmatory factor analysis indicates that ABI is best modeled as dimensions of a second-order formative trust construct rather than as its antecedents. However, PLS-SEM provides somewhat unconvincing support for the impacts of ABI-trust. Instead, qualitative comparative analysis (QCA) delineates that all three ABI dimensions are not always needed for P-J and P-V fit in supply chain. Some employees respond to affective-based (i.e. benevolence) trust and others to cognitive-based (i.e. ability and integrity) trust.

The QCA results offer specific recommendations for supply chain organizations to enhance employee trust in supervisors to succeed in the struggle for labor.

The results counter extant trust theory, encouraging scholars to consider ABI as distinct dimensions of trust. The study also demonstrates the importance of considering QCA in supply chain research to meaningfully expand contributions to theory and practice.

Much has been written about the importance of external integration for the integrity of food products. To achieve food integrity, all actors along the supply chain have to be fully integrated and comply with an assurance system or process. The more complex the supply chain operations are, the greater will be the need for integration. This research paper investigates the impact of external integration on compliance with halal standards, as an example of product integrity within the food industry.

A survey of 1,000 food manufacturers was conducted. Partial least squares structural equation modelling was used to test the effect of external integration on compliance with halal standards.

The results showed that there were links between halal assurance system and external integration. Nevertheless, it was discovered that only customer integration mediated the relationship between the halal assurance system and product quality and production cost.

The practical implications of the findings extend to managers in the food industry who might pursue supply chain integration as a structure to achieve excellence. The findings suggested that the deployment of a halal assurance system has a positive effect on operational performance. Furthermore, the results show that managers who wish to implement the halal assurance system should carefully invest in an external integration strategy, depending upon the operational performance improvement intended.

This research is one of the first studies to investigate the effects of external integration on halal food in general and is the first empirical investigation of the effect of safeguarding halal integrity on operational performance.

This paper argues that there is an absence of halal integrity within the conventional stages of a food chain. This paper adapts the understanding of the different stages and argues the need to develop a critical consciousness for halal integrity within the food chain to address the needs of the ever-growing Muslim consumers’ market. The purpose of this paper is to propose a definition of halal integrity using farm to fork and global food supply chain models.

The study includes a review of priori literature and media reports regarding cross-contamination of food products with haram (forbidden) components. This background will be used to conceptualise halal integrity using farm to fork and global supply chain models.

Different interpretations of halal – what is permitted and what is prohibited – exist for the different schools of Islamic legal thought and within the customs of different countries. In order to ensure that food production is embracive of the religious needs of the global Muslim customer market, this paper utilises the farm to fork and global supply chain models to foster a critical awareness of halal needs. Halal integrity should be clearly presenting the details of the halal status of the product and assuring that the requirements for halal as stated are met. Halal integrity not only deals with permitted and prohibited foods, but that the halal status of the food products (i.e. from raw materials until it reaches the consumers) should not be breached (i.e. no cross-contamination with haram products/methods and no ill intents). A formal definition of halal integrity has been proposed.

The SWOT analyses serve as a guideline as the analysis done may be outdated as the environments are constantly changing.

This research although academic is meant to have a real value in improving the integrity of the halal food supply chain, providing value to the food industry, to countries that are concerned about this supply chain and to Muslim consumers. Halal integrity is crucial to the success of the emerging halal market.

Halal supply chain management (HSCM) is an emerging research area and is in the early stage of evolution. This study aims to identify 11 critical factors towards effective management of a Halal supply chain (HSC) and provides a framework for the HSCM by evaluating Halal practices' impact on sustainability performance measures empirically.

A structured questionnaire-based survey has been carried out to collect data for analysis. The statistical analysis is accomplished by exploiting merits of factor analysis and structural equation modelling (SEM).

The results imply that out of 11 critical factors, nine factors on effective management of the HSC are statistically significant, and impacts of two critical factors are positive but statistically insignificant. In the structural model, the path coefficient of all success indicators are positive and statistically significant. In terms of the path coefficient of sustainable performance measures of HSC, all three dimensions, economic, environmental and social, are positive and statistically significant.

The research extends Halal and supply chain management's literature by proposing Halal as a standard quality control system, as it focuses on wholesome consumption. Effective management of the HSC is positively related to the firms' sustainable performance, thus helping managers make the organisation sustainable in the long term.

The research extends the literature of Halal and supply chain management by proposing Halal as a standard quality control system, which focuses on wholesome consumption. Effective management of the HSC is positively related to the sustainable performance of the firms, thus helps managers in making the organisation sustainable in the long term.

The result of the study underlines that sustainable performance measures are embedded in HSCM. This research develops a new paradigm in the research of HSCM and sustainability.

Muslim consumers have been shocked with the news of cross-contamination issues in the Halal food that they consumed. These issues make them put more effort in ensuring the products that they purchased being monitored throughout the supply chain. In this case, food companies must be prepared to implement systematic traceability system to ensure the authenticity of Halal products and comprehend the importance of Halal industry environmental factors (HIEF) in enhancing integrity of Halal food supply chain and protect from any risk of cross-contaminations. This paper aims to clarify the relationship between the Halal traceability system adoption (HTSA) and HIEFs on Halal food supply chain integrity (HFSCIn).

The study opted quantitative research approach by using the self-administrated questionnaires. The questionnaires were distributed during Malaysia International Halal Showcase (MIHAS) 2014 and Halal Fiesta Malaysia (HALFEST) 2014. 127 Malaysian Halal food and beverages companies have been involved in the study. Most of the respondents are the general manager or owner of the company, Halal executives, quality assurance managers, operation managers and sales manager.

The study found that there is a significant relationship between HTSA and HIEF on HFSCIn. The study also found that the highest adoptions of Halal traceability system are among the producer and end user, while the highest contributions in influencing the HIEF are the economic and socio-cultural factors.

This study only focused on Halal food industry particularly the food and beverages category. Thus, future study can explore further on every category in food industry such as raw materials and ingredients; poultry, meat and dairy; fast food and premises and make comparison between pharmaceutical, cosmetics and health care in Halal industry. In addition, the sample size (N = 127) can be considered small; therefore, it is recommended that in future the subject matter be explored with a much larger sample to allow generalization of the result.

This study provided, perhaps for the first time, an analysis of the relationship between traceability adoptions and HIEF on HFSCIn.

The purpose of this paper is to establish a conceptual model adopted from a strategy-structure-performance paradigm for investigating the fit between the supply chain integration and halal food supply chain integrity and the impact of halal food supply chain integrity on firms’ performance in a Malaysian context.

This study comprises a sample of a halal manufacturing firm in Malaysia. A cross-sectional research design was used in this study. Data were gathered based on mailed and personally administered questionnaires. SmartPLS was used to analyse the 254 valid responses.

The research findings indicate that internal integration and strategy have positive impact on halal food supply chain integrity. The study results confirmed that customer integration and supplier integration contributes to halal food supply chain integrity. It also finds that halal food supply chain integrity has a significantly positive impact.

The results suggested that a strategic collaboration with the supplier pivoted around the quality and integrity of the raw materials should be undertaken.

The results from this study supports that the managers should adopt all halal food supply chain integrity components to achieve a superior performance. Even though some of the components did not yield significant results in terms of their relationships with firms’ performance, these dimensions were generally related to the standardised industry requirements, such as certifications.

The findings are original and unique and are based on established theories from the literature on supply chain management practices. The research findings are useful to academics and policymakers interested in fostering a halal supply chain in Malaysia.

Even though trust is known for improving supply chain performance (SCP), previous studies have overlooked the investigation of its dimensions. Limited studies exist on the variations of the influence of trust dimensions in agribusiness supply chain relationships. This study examined the influence of trust dimensions on SCP in a developing country's context.

A cross-sectional study design was used to collect from 204 farmers and 192 traders (396 respondents) using a multistage sampling approach. Structural equation modeling was employed to analyze the hypothesized relationships.

Pooled sample results show that integrity and competence were the trust dimensions with significant effects on SCP, whereas competence was significant across different supply chains and markets, integrity and benevolence were only significant along fresh chains and in the contract market.

The extent of application of this study's findings is limited to situations similar to those of tomato and soybeans value chains in developing countries.

The paper contributes to a better understanding of the influence of trust dimensions on SCP across supply chains in different market typologies in agribusiness relationships in a developing country's context.

The complex network structure causes several disruptions in the supply chain that make risk management essential for supply chain management including halal supply chain (HSM). During risk management, several challenges are associated with the risk assessment phase, such as incomplete and uncertain information about the system. To cater this, the authors propose a risk assessment framework that addresses the issues of uncertainty using neutrosophic theory and demonstrated the applicability of the proposed framework through the case of halal supply chain management (HSCM).

The proposed framework is using the capabilities of the neutrosophic number which can handle uncertain, vague and incomplete information. Initially, the risk related to the HSC is identified through a literature review and expert’s input. Further, the probability and impact of each HSM-related risk are assessed using experts’ input through linguistic terms. These linguistic values are transformed into single-value trapezoidal neutrosophic numbers (SVTNNs). Finally, the severity of each HSM-related risk is determined through the multiplication of the probability and impact of each risk and prioritised the risks based on their severity.

A comprehensive risk assessment framework is developed that could be used under uncertainty. Initially, 16 risks are identified related to the HSM. Further, the identified risks are prioritised using the severity of the risks. The high-priority risk is “raw material status”, “raw material wholesomeness” and “origin of raw material” while “information integrity” and “people integrity” are low-priority risks.

HSM risk can be effectively assessed through the proposed framework. The proposed framework applied neutrosophic numbers to represent real-life situations, and it could be used for other supply chains as well.

The proposed method is effectively addressing the issue of linguistic subjectivity, inconsistent information and uncertainty in the expert’s opinion. A case study of the HSC is adopted to illustrate the efficiency and applicability of the proposed risk framework.
