The asymptotic behavior of a tri-trophic food chain model in the chemostat is studied. The Monod-Herbert growth model is used for all trophic levels. The analysis is carried out numerically, by finding both local and global bifurcations of equilibria and of limit cycles with respect to two chemostat control parameters: the dilution rate of the chemostat and the concentration of input substrate....

The extent to which antibiotics given to animals contribute to the overall problem of antibiotic resistance in man is still uncertain. The development of resistance in some human pathogens, such as methicillin-resistant Staphylococcus aureus and multi-drug resistant Mycobacterium tuberculosis, is linked to the use of antimicrobials in man and there is no evidence for animal involvement. However...

Risk and uncertainty are ubiquitous and varied in agri-food supply chains. As environment volatility increases, only having capabilities to manage agri-food supply chain risks may not be enough, resilience factors also need to be integrated into daily operations. This paper undertakes a systematic literature review on risks sources and resilience factors in agri-food supply chains. A five-stage...

It is often suggested that food supply chains are typical for what can be achieved in supply chain management. This paper challenges this believe by investigating the possibilities and limitations for supply chain integration for food processing companies. We argue that a combination of typical food characteristics and the use of shared resources limit the possibility for integration, while unc...

This article synthesizes the evidence on food value chains (FVCs) and regional hubs (RFHs) through a systematic literature review suggests future research directions based gaps identified in review. The number of publications FVCs RFHs is increasing, indicating that these topics are gaining interest among scholars from different countries disciplines. Bibliometric analysis preferred reporting i...

Abstract This study gives on overview of food safety tools that have been developed recently through the perspective animal origin supply chain. It introduced some expected legal issues, new technological outbreaks, culture outlined in latest versions management system standards and applicable for entire chains. Finally, paper briefly shows incentives associated with Covid-19 as well role UN Su...
