ABSTRACT Challenges posed by changes in livestock production in emerging food producing areas and demographic development and climate change require new approaches and responsibilities in the management of food chains. The increasingly recognized role of primary food producers requires the support of the scientific community to instruct effective approaches based on scientific data, tools, and expertise. Mali is an emerging food producing area, and this review covers (i) the dairy farming scenario and its environment, (ii) the role of dairy production in food security, including the greatly different animal rearing systems in the Sahel and tropical regions, (iii) risk management pillars as modern infrastructures, effective farmer organizations, and institutional systems to guarantee animal health and safety of products, and (iv) feasible interventions based on good practices and risk assessment at the farm level (e.g., sustainable use of fertilizers, feeds, veterinary drugs, and pesticides) to protect consumers from food safety hazards. Social innovation based on the empowerment of the primary food producers emerges as crucial for sustainable and safe food production. Sustainable policies should be supported by the mobilization of stakeholders of One Health, which is a science-based approach to linking human health and nutrition with the health and management of food producing animals and environmental safety. In the context of the complex, multifaceted scenario of Mali dairy production, this article presents how a cost-effective animal health and food safety scheme could be established in the dairy production chain. Because milk is a major commodity in this country, benefits could be derived in food security, public health, the resilience of the farming system, animal husbandry, and international trade.

Antimicrobial resistance (AMR) is a global problem and there has been growing concern associated with its widespread along the animal–human–environment interface. The farm-to-fork continuum was highlighted as a possible reservoir of AMR, and a hotspot for the emergence and spread of AMR. However, the extent of the role of non-antibiotic antimicrobials and other food-related stresses as selective factors is still in need of clarification. This review addresses the use of non-antibiotic stressors, such as antimicrobials, food-processing treatments, or even novel approaches to ensure food safety, as potential drivers for resistance to clinically relevant antibiotics. The co-selection and cross-adaptation events are covered, which may induce a decreased susceptibility of foodborne bacteria to antibiotics. Although the available studies address the complexity involved in these phenomena, further studies are needed to help better understand the real risk of using food-chain-related stressors, and possibly to allow the establishment of early warnings of potential resistance mechanisms.

The real-time and dissemination characteristics of network information make net-mediated public opinion become more and more important food safety early warning resources, but the data of petabyte (PB) scale growth also bring great difficulties to the research and judgment of network public opinion, especially how to extract the event role of network public opinion from these data and analyze the sentiment tendency of public opinion comment. First, this article takes the public opinion of food safety network as the research point, and a BLSTM-CRF model for automatically marking the role of event is proposed by combining BLSTM and conditional random field organically. Second, the Attention mechanism based on vocabulary in the field of food safety is introduced, the distance-related sequence semantic features are extracted by BLSTM, and the emotional classification of sequence semantic features is realized by using CNN. A kind of Att-BLSTM-CNN model for the analysis of public opinion and emotional tendency in the field of food safety is proposed. Finally, based on the time series, this article combines the role extraction of food safety events and the analysis of emotional tendency and constructs a net-mediated public opinion early warning model in the field of food safety according to the heat of the event and the emotional intensity of the public to food safety public opinion events.

In recent years, large food distributors poured considerable effort in the definition of private standards of food safety for their products. Despite these efforts, medium and large retailers have yet to begin advertising to their consumers the adoption of such standards and, in doing so, do not actively pursue a diversification strategy for their products. This behavior seems paradoxical as large retailers would benefit from product differentiation. This article focuses on the role of standards in the coordination of the supply channels and proposes a theoretical model that gives an economic motivation to the current behavior of large retailers. The first objective of this study is to demonstrate how the adoption of standards is a rational choice for large retailers, even in the case in which consumers are not willing to pay for food safety. The reason is that standards can also be used to solve information asymmetry problems and organize the supply chain. Secondly, the theoretical model of contracts suggests that, investments related to the promotion of standards to the consumers, might, under certain conditions, undermine the profits of the large distribution.

Verotoxin-producing Escherichia coli (VTEC) have emerged in the past two decades as food-borne pathogens that can cause major outbreaks of human illnesses worldwide. The number of outbreaks has increased in recent years due to changes in food production and processing systems, eating habits, microbial adaptation, and methods of VTEC transmission. The human illnesses range from mild diarrhea to hemolytic uremic syndrome (HUS) that can lead to death. The VTEC outbreaks have been attributed to O157:H7 and non-O157:H7 serotypes of E. coli. These E. coli serotypes include motile (e.g., O26:H11 and O104:H21) and nonmotile (e.g., O111:H–,0145:H–, and O157:H–) strains. In the United States, E. coli O157:H7 has been the major cause of VTEC outbreaks. Worldwide, however, non-O157:H7 VTEC (e.g., members of the 026, O103, O111, O118, O145, and O166 serogroups) have caused approximately 30% of the HUS cases in the past decade. Because large numbers of the VTEC outbreaks have been attributed to consumption of ruminant products (e.g., ground beef), cattle and sheep are considered reservoirs of these food-borne pathogens. Because of the food safety concern of VTEC, a global perspective on this problem is addressed (Exp Biol Med Vol. 228, No. 4). The first objective was to evaluate the known non-O157:H7 VTEC strains and the limitations associated with their detection and characterization. The second objective was to identify the VTEC serotypes associated with outbreaks of human illnesses and to provide critical evaluation of their virulence. The third objective was to determine the rumen effect on survival of E. coli O157:H7 as a VTEC model. The fourth objective was to explore the role of intimins in promoting attaching and effacing lesions in humans. Finally, the ability of VTEC to cause persistent infections in cattle was evaluated.
