The presence of heavy metals in milk causes many acute and chronic physiological dysfunctions in human organs. The present study aims to investigate the heavy metals in cow's and buffalo's milk of two major cities, Karachi and Gujranwala, Pakistan to estimate metal intake by humans from this source.

In total, 48 milk samples from 2 cities were drawn from animals' udder to avoid contamination. Each sample was digested with nitric acid at 105 ^oC (degree Celsius) on a pre-heated electric hot plate to investigate the metals by atomic absorption spectroscopy (flame type). Air-acetylene technique analyzed chromium, cadmium and lead, and the hydride method analyzed arsenic in the milk samples.

The results revealed the highest mean lead concentration (19.65 ± 43.86 ppb) in the milk samples, followed by chromium (2.10 ± 2.33 ppb) and arsenic (0.48 ± 0.73 ppb). Cadmium was not detected in any sample, assuming cadmium's occurrence was below the detection level. The concentrations of all the metals in the samples of the two cities do not differ statistically. Lead concentrations in the buffalo's milk were higher than in cow's milk (p < 0.05). However, the concentrations of arsenic and chromium between buffalo's and cow's milk do not differ statistically. The present study reveals a lower level of metals in the milk than those conducted elsewhere. The mean concentrations of all the metals met the World Health Organization's (WHO) safety guidelines (1993).

Although cadmium causes toxicity in the human body, cadmium could not be measured because cadmium's concentration was below the detection level, which is 1 ppb.

This study will help reduce the toxic metals in our environment, and the sources of heavy metals, particularly from the industrial sector could be identified. The feed and water consumed by the milking animals could be carefully used for feeding them.

This study will help reduce the diseases and malfunction of human organs and organ systems since these heavy metals cause toxicity and carcinogenicity in humans. Arsenic and chromium cause cancer while lead causes encephalopathy (a brain disease).

The study reports heavy metal concentrations in the two attributes of four independent variables of raw milk samples that were scarcely reported from Pakistan.

This paper aims to investigate the impact of halal awareness on the relationship between halal supply chain knowledge and purchase intention for halal meat products in the millennial generation.

The quantitative approach with the respondents of 177 millennial generations in Indonesia is selected to understand the relationships between variables. Structural equation model-partial least square is used to analyze the relationship between variables.

The findings of this study found that the purchase intention of halal products in the millennial generation is influenced by several factors such as halal supply chain knowledge, halal certification and logo and religious beliefs. However, the results of this study also show that concern for halal products failed to moderate the relationship between these three main variables on the purchase intention of halal products.

This study provides insights into the concern that strengthens the relationship between the main variables on the intention to purchase halal meat products for the millennial generation.

This study aims to highlight the influence of co-creation experience (CCE) on tourists’ citizenship behavior (TCB), emphasizing the Indonesian ecotourism sector during the post-COVID pandemic.

By using a judgmental sampling, data were collected from 150 visitors who visits Indonesian ecotourism resort and acquired the wildlife experience through co-creation process. To evaluate the relationship model, partial least squares-structural equation modeling by SmartPLS 3rd version was used in this study.

The result indicated that CCE in terms of Indonesian ecotourism had an effect on involvement (INV) and satisfaction (SAT). Result ascertain INV and SAT direct effect on TCB. Multigroup analysis indicated that perceived risk of COVID-19 could moderate insignificantly the relationship among INV, SAT on TCB.

This study focuses on CCE, INV, SAT and TCB in Indonesian ecotourism with wildlife attraction and contributes an insight for tourism research; thus, the results cannot be generalized for other ecotourism worldwide.

The proposed model of this study suggests the need to review the current condition of citizenship behavior at destination level, especially regarding to cleanliness and crowd controlling on post-COVID pandemic to maintain tourists’ health and safety while traveling.

Achieving TCB in different types of destination (ecotourism) requires specific development models concerning environmental conditions.

Though CCE, INV, SAT and TCB have identified as main topics for tourism research especially in ecotourism sector, the related factors of TCB in post-COVID-19 era are remain limited.

本研究旨在强调共创体验（CCE）对游客公民行为（TCB）的影响, 重点是后疫情期间印尼生态旅游中的游客公民行为（TCB）。

通过判断抽样, 从访问印尼生态旅游胜地的 150 名游客收集了数据, 并通过共创过程获得了其野生动物体验。 为了评估关系模型, 本研究使用了 SmartPLS 第三版的偏最小二乘结构方程建模 (PLS-SEM)。

结果表明, 印尼生态旅游的 CCE 对参与度（INV）和满意度（SAT）有影响。 结果确定了INV和SAT对TCB的直接影响。 多组分析表明, covid-19 的感知风险对 INV 和 SAT 与 TCB 的关系影响不大。 本研究还描述了中介作用。

该研究重点关注印尼生态旅游中野生动物吸引力的CCE、INV、SAT, TCB, 为旅游研究提供见解; 因此, 研究结果不能推广到全世界其他生态旅游。

该研究提出的模型表明, 有必要审查目的地层面公民行为的现状, 特别是在新冠大流行后的卫生和人群控制方面, 以维护游客在旅行时的健康和安全。

在不同类型的目的地（生态旅游）中实现游客的公民行为需要针对不同的环境条件而选择开发模式。

尽管 CCE、INV、SAT 和 TCB 是旅游研究中, 特别是在生态旅游领域的重点研究对象, 但在后疫情旅游过程中, 其与目的地公民行为相关的因素研究仍然有限。

Este estudio pretende poner de relieve la influencia de la experiencia de cocreación (CCE) en el comportamiento ciudadano de los turistas (TCB) haciendo hincapié en el sector del ecoturismo indonesio durante el periodo post-pandémico de la COVID-19.

Mediante el uso de un muestreo de juicio, se recopilaron datos de 150 visitantes que visitaron un centro de ecoturismo en Indonesia y adquirieron la experiencia de la vida silvestre a través del proceso de co-creación. Para evaluar el modelo de relación, en este estudio se utilizó el modelo de ecuaciones estructurales de mínimos cuadrados parciales (PLS-SEM) de SmartPLS 3.^a versión.

El resultado indicó que la CCE en términos de ecoturismo indonesio tuvo un efecto sobre la implicación (INV) y la satisfacción (SAT). El resultado determinó que INV y SAT tienen un efecto directo sobre el TCB. El análisis multigrupo indicó que el riesgo percibido del covid-19 modera de forma insignificante la relación INV y SAT con el TCB. Papel mediador también descrito en este estudio.

el estudio se centra en CCE, INV, SAT, TCB en el ecoturismo indonesio con atracción de vida silvestre y aporta información para la investigación turística; por lo tanto, los resultados no pueden generalizarse para otros ecoturismos en todo el mundo.

el modelo propuesto en el estudio sugiere la necesidad de revisar la condición actual del comportamiento ciudadano a nivel de destino, especialmente en lo relativo a la limpieza y el control de multitudes en la etapa poscovid para mantener la salud y la seguridad de los turistas durante el viaje

lograr un comportamiento ciudadano de los turistas en diferentes tipos de destino (ecoturismo) requiere modelos de desarrollo específicos en relación con las condiciones ambientales.

aunque CCE, INV, SAT y TCB se identifican como una prioridad para la investigación turística, especialmente en el sector del ecoturismo, los factores relacionados en el curso del turismo post-covid-19 que se relacionan con la ciudadanía a nivel de destino siguen siendo limitados.

This study aims to explore the grain chain in Kosovo. This study also aims to analyse the role of actors involved in the supply, production, processing, marketing and distribution of the grain value chain.

The study uses qualitative methods. A total of 60 semi-structured interviews are conducted with actors involved in the entire grain value chain.

Findings reveal that the country depends on grain imports and lacks an organised grain market, which is often distorted by the present political situation. Stakeholders are partly integrated in the grain value chain, and they are not very efficient in production. The existence of an informal market influences the decision-making of actors involved in the grain chain. The grain value chain displays mixed governance types, and the relationships among actors are based on the trust mechanism.

The research draws the importance of agriculture’s public policies to sustain domestic grain production. Public–private partnerships should be created to restore the grain market. Trading policies should be revised because they play a crucial role in enhancing fair competition between domestic and foreign traders.

It is globally recognized that food waste has significant economic, social and environmental impacts. This study endeavors to identify the individuals' underlying factors that affect food waste behavior in a social context in Egypt.

Due to the scarcity of research illustrating food waste in a social context, a qualitative research paradigm is employed. In-depth semi-structured interviews are conducted with 18 Egyptian households to report their experiences, thoughts and feelings while eating in a social context.

Based on thematic analysis using grounded theory procedures, eight main elements affecting creation and reduction of food waste in social contexts are identified. Additionally, the authors investigate the role of emotions in social dining contexts. A key finding is that food waste in social events is inevitable and is the acceptable norm in the Egyptian culture. Thus, the first step to reduce food waste is paying more attention to change culture. Persuading people with the negative consequences of food waste issue on behalf of their cultural values will be more challenging and may require more innovative approaches.

Although food waste issue is one of the contemporary issues in the world, very little is known about how social food consumption leads to food waste behavior. This study employs social influence theory and the collectivistic culture orientation to investigate the unanswered question of why food gets wasted in social meal context.

The 2008 Chinese melamine milk scandal resulted in six reported fatalities and affected around 300,000 children, of whom 54,000 were hospitalised. Previous studies have used linear approaches to examine the root causes of the melamine milk scandal.

In the present study, we applied a systems approach to the melamine milk scandal to identify the complex systems-level failures across the supply chain leading to the incident and why food fraud incidents such as this occurred in the dairy sector. Additionally, systemic failures associated with food fraud vulnerability factors were considered (i.e. opportunities, motivation and control measures).

48 contributory factors of influence were identified and grouped across six sociotechnical levels across the Chinese dairy system, from government to equipment and surroundings. Lack of vertical integration (processes and communication) contributed to the failure. When viewed from a broader perspective, the melamine milk scandal can be linked to a series of human errors and organisational issues associated with government bodies, the dairy supply chain, individual organisations and management decisions and individual actions of staff or processes.

This approach is of value to policymakers and the industry as it supports public health investigations of food fraud incidents and proactive food safety management.

To the best of our knowledge, this is the first study to analyse a food safety or fraud incident using the AcciMap approach and the food fraud vulnerability assessment (FFVA) technique. AcciMap analysis is applied to both unintentional and intentional aspects of the incident.

Manufacturing companies continue to encounter a diverse set of obstacles while embracing sustainable development goals. Accordingly, the purpose of this study is to explore critical sustainable development-related barriers to flexible packaging manufacturing companies in the New Zealand context.

Drawing on a qualitative multiple case studies approach, the authors collected data from the New Zealand flexible packaging industry. Semistructured interviews were conducted with the senior corporate managers in two large flexible packaging companies. Following the thematic analysis approach, the authors analyzed the information collected from the participants and synthesized our findings under the key dimensions of internal and external barriers to sustainable development.

The findings revealed that internal barriers to sustainable flexible packaging are linked to economic, operational and technical issues. Conversely, external barriers include global crises and disruption, customer behavior and preferences and institutional and infrastructural-related aspects. Based on the analysis of empirical findings, the authors further identified the underlying reasons for sustainable flexible packaging barriers and recommended guidelines that could assist corporate managers and policymakers in addressing obstacles inhibiting the flexible packaging industry from adopting sustainable business practices.

The authors argue that this study is one of the early studies to consider inhibiting factors to incorporate sustainable development into the New Zealand flexible packaging industry context. Building on a range of theoretical perspectives, the authors extend the current body of knowledge seeking to advance the sustainable development agenda in the New Zealand flexible packaging industry and offer recommended pathways fostering sustainable development in a distinctive manufacturing context.

The growing awareness of climate risks associated with food safety issues has drawn the attention of stakeholders urging the food industry to carry out a sustainable food safety management system (FSMS). This study aims to investigate whether the critical success factors (CSFs) of sustainable FSMS can contribute to achieving climate neutrality, and how the adoption of FSMS 4.0 supported by the Industry Revolution 4.0 (IR 4.0) technologies moderates the impact of the CSFs on achieving climate neutrality.

Survey data from 255 food production firms in China and Vietnam were utilised for the empirical analysis. The research hypotheses were examined using structural equations modelling (SEM) with route analysis and bootstrapping techniques.

The results show that top management support, human resource management, infrastructure and integration appear as the significant CSFs that directly impact food production firms in achieving climate neutrality. Moreover, the results demonstrate that the adoption of FSMS 4.0 integrated with the three components (ecosystems, quality standards and robustness) significantly moderates the impact of the CSFs on achieving climate neutrality with lower inputs in human resources, infrastructure investment, integration and external assistance, and higher inputs in strengthening food safety administration.

This study provides empirical findings that fill the research gap in understanding the relationship between climate neutrality and the CSFs of sustainable FSMS while considering the moderating effects of the FSMS 4.0 components. The results provide theoretical and practical insights into how the food production sector can utilise IR 4.0 to attain sustainable FSMS for achieving climate neutrality.

The global outbreak of COVID-19 and its subsequent varied impacts on different economic activities necessitate to examine its disruptions and impacts on livestock sector in India due to its recently surging potential as an unrivaled alternative to boost farmer’s income.

The studies for review were identified through search in different databases using relevant keywords. Only full text papers written in English language were reviewed. The review was organized and streamlined using Covidence software.

Analysis of the literature reveals adverse effects of COVID-19 on functioning of input and output stages of livestock supply chains. This has resulted in upstream and downstream economic losses that affect livelihoods of the producers.

Scale of unprecedented crisis due to COVID-19 pandemic requires creative policy decisions to make livestock production systems robust, resilient and sustainable. Organized production systems are required to integrate with livestock-tech startups to modernize their supply chains, whereas local supply chains are required to reorient with government’s intervention in terms of developing on-farm production and postproduction processing facilities.

Although there exist some evidence on COVID-19-related impacts on livestock sector of India, but an integrated review of evidence on COVID-19 related disruptions at all the stages (from input supply to marketing) of livestock supply chains was missing.

The purpose of this paper is to guide commercial and policy action to improve smallholder Indonesian cattle systems.

A survey (n = 304) of smallholder cattle farms in six villages in two districts of Nusa Tenggara Barat, Indonesia. Principal component analysis (PCA) and cluster analysis (CA) were employed to classify cattle farms into business models according to observed innovation. Differences between business models were identified using a one-way-analysis-of-variance (ANOVA).

Four business models were identified, representing profiles of innovation adoption and elements of business models, socio-economic characteristics, farming system and performance variables including revenue, cost and profit. The business models display a range of orientation to buyer requirements and a range of approaches to production, indicating a need to promote in a variety of ways the change from supply-push to demand-pull in the cattle value chain.

This study offers guidance on how business models might be strengthened over time, by using simple indicators of performance and the models' linkage to innovation in the context of each business model. The business models developed here, and refinements to them based on localised conditions, offer a targeted and accelerated pathway to improved performance in smallholder systems.

This study proposed a novel approach to the recognition of business models based on innovation.
