Cultured meat involves producing meat from animal cells, not from slaughtered animals. This innovation has the potential to revolutionize the meat industry, with wide implications for the environment, health and animal welfare. The main purpose of this paper is to stimulate some economic research on cultured meat. In particular, this paper includes a prospective discussion on the demand and supply of cultured meat. It also discusses some early results on the environmental impacts of cultured meat, emphasizing the promises (e.g., regarding the reduction in land use) but also the uncertainties. It then argues that cultured meat is a moral improvement compared to conventional meat. Finally, it discusses some regulatory issues, and the need for more public support to the innovation.

Most infectious diseases in humans originate from animals. In this paper, we explore the role of animal farming and meat consumption in the emergence and amplification of infectious diseases. First, we discuss how meat production increases epidemic risks, either directly through increased contact with wild and farmed animals or indirectly through its impact on the environment (e.g., biodiversity loss, water use, climate change). Traditional food systems such as bushmeat and backyard farming increase the risks of disease transmission from wild animals, while intensive farming amplifies the impact of the disease due to the high density, genetic proximity, increased immunodeficiency, and live transport of farmed animals. Second, we describe the various direct and indirect costs of animal-based infectious diseases, and in particular, how these diseases can negatively impact the economy and the environment. Last, we discuss policies to reduce the social costs of infectious diseases. While existing regulatory frameworks such as the “One Health” approach focus on increasing farms’ biosecurity and emergency preparedness, we emphasize the need to better align stakeholders’ incentives and to reduce meat consumption. We discuss in particular the implementation of a “zoonotic” Pigouvian tax, and innovations such as insect-based food or cultured meat.

Metaphors are increasingly recognized as influencing cognition and consumption. While these linkages typically have been qualitatively generated, this article presents a framework of convergent quantitative methodologies that can further document the validity of a metaphor. To illustrate this multimethod framework, the authors explore whether there is a metaphoric link between meat and maleness in Western cultures. The authors address this in six quantifiable studies that involve (1) implicit associations, (2) free associations, (3) indirect-scenario-based inferences, (4) direct measurement profiling, (5) preference and choice, and (6) linguistic analysis and conclude that there is a metaphoric relationship between mammal muscle meat and maleness.

Psychrotrophic Pseudomonas species are the key spoilage bacteria of aerobically stored chilled meat. These organisms readily form biofilms on meat under refrigerated conditions leading to consumer rejection and associated economic losses. Limited information is available on the matrix composition of the biofilms formed by these bacteria. We quantified and characterized the main components of the matrix of mono-species biofilms of selected Pseudomonas fragi and Pseudomonas lundensis strains using chemical analysis and Raman spectroscopy. The biofilms were grown at 10 °C and 25 °C on nitro-cellulose membranes placed on surface sterilized beef cuts. Extra-cellular polymeric substances of the matrix were extracted in soluble and bound forms and were chemically assessed for total carbohydrates, proteins and extra-cellular DNA. Both Pseudomonas species showed a significant increase in total carbohydrates and total proteins when grown at 10 °C as compared to 25 °C. Extra-cellular DNA did not show a strong correlation with growth temperature. Raman spectra were obtained from planktonic bacteria and membrane grown biofilms at 10 °C and 25 °C. Higher levels of guanine were detected in planktonic cells as compared to biofilm cells. This study suggests that psychrotrophic Pseudomonas species may respond to cold stress by increasing extra-cellular polymer secretions.

The aim of this work was to study the influence of different cooking methods (grilling, roasting, boiling, steaming and frying) on cooking loss and lipid oxidation of buffalo meat (Semimembranosus). Cooking induces significantly cooking loss and lipid oxidation (TBARs index) in meat product (P<0.05). When the different cooking methods were examined, grilling method showed lesser extent of cooking loss and higher level of MDA concentration compared to steaming which was observed with higher cooking loss but lower level of MDA concentration (P<0.05). There were no significant differences on cooking loss and MDA concentration among the rest of the cooking methods (P>0.05). The cooking loss was found to be related to MDA level with r= -0.54 (P<0.05). It has been suggested in this study that cooking loss could be possible response to MDA level in buffalo meat product.

Rising global demand for meat will result in increased environmental pollution, energy consumption, and animal suffering. Cultured meat, produced in an animal-cell cultivation process, is a technically feasible alternative lacking these disadvantages, provided that an animal-component-free growth medium can be developed. Small-scale production looks particularly promising, not only technologically but also for societal acceptance. Economic feasibility, however, emerges as the real obstacle.

PurposeAlthough the livestock sector is considered to be an important segment of the Saudi Arabian economy, its contribution, including the multiple sources of commercial income it provides, is underestimated. This industry provides thousands of jobs in various related sectors and meets national demand for food. This study aims to examine the impact of breeding inputs such as animal production, marketing processes and operation and legislation on livestock sector efficiency and strategic food security.Design/methodology/approachThis study adopted an exploratory approach. The sample consisted of specialists in industrial production and livestock breeders in the northern region of Saudi Arabia. The relative importance index was used to analyze the data, which was evaluated using structural equation modeling in SPSS.FindingsThe results show the significant influence of breeding inputs, markets and legislation on increasing the efficiency of the livestock sector and the impact of livestock on strategic food security. They also highlight the need to motivate governments to focus on this sector, especially by reducing taxes on breeders’ income and lowering livestock costs accordingly. The Saudi Arabian Government should also facilitate innovative agreements to create global markets for the export of surplus livestock products. In addition, a marketing process is lacking in all areas of production and the local and international marketing of livestock products, which requires the support of different sources of fodder and establishment of markets for specific types of meat slaughter, packaging and sales.Research limitations/implicationsThis research was limited to the northern region of Saudi Arabia.Practical implicationsThis study highlights the importance of marketing processes and activities according to marketing operations as they used in study instrument to explore their impact on in the marketing livestock sector for national food security strategies and guides future studies in this field.Social implicationsThis research recommends that decision-makers support marketing in the livestock sector and reduce production taxes.Originality/valueTo the best of the author’s knowledge, no previous related research has been conducted in the field of food security.

Purpose Halal frozen meat product returns are major challenges in the halal frozen meat supply chain because of the sheer volume and processing costs of returns. The purpose of this paper is to investigate the effect of integrated halal supply chain (IHSC) strategies on effective product returns with halal logistics (HL) as an interceding variable. Design/methodology/approach This paper used the cross-sectional technique to select samples from a population that revolved around the halal food industry in Malaysia. Data collected from halal service providers who handle halal frozen meat product returns provided insightful findings. Findings The findings of this paper indicate that the IHSC dimensions, such as interactive fairness, procedural fairness and service coverage, are positively associated with effective product returns. It also shows that HL plays a mediating role between the IHSC and effective product returns. Practical implications From a practical viewpoint, this paper suggests that an effective return service system can be designed to emphasise the category of interactive and flexible justice services through refunds or product replacement, depending on customer's demand. Originality/value The result of this paper provides insights into how logistics service provider managers effectively and efficiently handle the halal supply chain network when involving product returns.

Wild animals play an integral and complex role in the economies and ecologies of many countries across the globe, including those of West and Central Africa, the focus of this policy perspective. The trade in wild meat, and its role in diets, have been brought into focus as a consequence of discussions over the origins of COVID-19. As a result, there have been calls for the closure of China’s “wet markets”; greater scrutiny of the wildlife trade in general; and a spotlight has been placed on the potential risks posed by growing human populations and shrinking natural habitats for animal to human transmission of zoonotic diseases. However, to date there has been little attention given to what the consequences of the COVID-19 economic shock may be for the wildlife trade; the people who rely on it for their livelihoods; and the wildlife that is exploited. In this policy perspective, we argue that the links between the COVID-19 pandemic, rural livelihoods and wildlife are likely to be more complex, more nuanced, and more far-reaching, than is represented in the literature to date. We develop a causal model that tracks the likely implications for the wild meat trade of the systemic crisis triggered by COVID-19. We focus on the resulting economic shockwave, as manifested in the collapse in global demand for commodities such as oil, and international tourism services, and what this may mean for local African economies and livelihoods. We trace the shockwave through to the consequences for the use of, and demand for, wild meats as households respond to these changes. We suggest that understanding and predicting the complex dynamics of wild meat use requires increased collaboration between environmental and resource economics and the ecological and conservation sciences.

Abstract The apocryphal scripture \"Epistula Apostolorum\" represents an important stage in the second century development of the concept regarding the resurrection of the flesh. For the first time, in this text, the Lord's resurrected body appears with the closely related promise of resurrection for the faithful, which is placed at the center of the discussion in the post-apostolic age. Thus, the crucial question arises: How is the idea of the resurrection of the flesh represented in the Epistula Apostolorum? The epistle provides the following answer: The resurrected receive an everlasting garment that no longer participates in the material creation. Nevertheless, the personality of those living on earth is preserved through the resurrection of the flesh. They do not exchange their identity as a result of the eschatological event; rather they maintain their former earthly personhood, but will exist in a glorified state of the resurrected flesh.
