Worldwide, food safety incidents can have a significant impact on public health, economies, agrifood trade, food security, and public confidence in the food supply. The prevention, mitigation, and management of food safety incidents globally can be enhanced through more effective early warning systems for food safety. Early warning systems help countries to better anticipate food safety threats and respond quicker through appropriate risk management actions. This publication provides a resource for countries to enhance their early warning capabilities and capacities. It emphasizes the need to build and connect links between existing food safety infrastructure (e.g. surveillance and food control) and to improve collaborative relationships among all of the different food chain stakeholders in order to protect public health and the food supply.

Early warning (EW) systems have a critical role in the reduction of risks from various hazards. The capability and capacity to identify early signals and emerging food safety risks, and to provide on-time EW that would allow for the mitigation of related upcoming risks have therefore become vital for national and international authorities and organizations dealing with food safety. The developments in early warning systems show a shift from reactive towards proactive systems. With the rapid development of modern systems fed by numerous, real-time and diverse data, as well as the advancements achieved in artificial intelligence and machine learning techniques, increasingly tested and validated digital methods and models have become available for food safety early warning and analysis. This technical background report enhances the awareness of the available evidence-based innovative digital tools and provides technical background information to support their use for proactive food safety early warning.

Agrifood systems require sustained growth to maintain food security for the global population, while facing unprecedented pressure from challenges of climate change and resource depletion. In this context, evaluating, holistically planning and transitioning to circularity will be critical to improve sustainability and face those challenges. While circular economy initiatives offer considerable promise in improving sustainability and increasing performance, these benefits are juxtaposed by the increasing evidence that contaminants, physical, microbiological or chemical, can get introduced, persist and potentially lead to unsafe food. Therefore, protecting food safety is key for the success of transitioning our current linear agrifood system to a more sustainable and circular one. This report provides a synthesis of current and emerging evidence of food safety risks in circular agrifood initiatives, with an aim to understand challenges and opportunities to manage and enhance food safety. Food safety has to be an equal performance indicator for any transition, requiring addressing data gaps, focusing research efforts and exploring opportunities for improving food safety outcomes. All parties in the agrifood system need to proactively do their part to ensure agrifood systems develop, by harnessing the innovation in this area, and at the same time produce safe food.

Lipid-based nutrient supplements (LNS) and ready-to-use therapeutic food (RUTF) are used to prevent and treat malnutrition in children. [Author] They are often produced in regions experiencing food insecurity and include edible oils obtained from oleaginous seeds or fruits that must be refined to remove undesirable substances and ensure adequate shelf-life for the product. [Author] However, the formation of the heat-induced contaminants 3-monochloropropane-1,2-diol (3-MCPD) fatty acid esters and glycidyl fatty acid esters (GEs) may occur during the refining process of edible oils. [Author] 3-MCPD and its fatty acid esters are present in many other foodstuffs and most of the total lifetime exposure is attributed to foods other than LNS/RUTF. [Author] While the only Codex standard developed for 3-MCPD is for liquid condiments containing acid hydrolyzed vegetable proteins, no Codex standards are available for GEs. [Author] This publication provides an overview of risk assessments for 3-MCPD and GEs previously performed by the Joint FAO/WHO Expert Committee on Food Additives (JECFA), European Food Safety Authority (EFSA) and other authorities, based on chronic exposure. [Author] The use of LNS/RUTF is intended to be of finite duration and confined to a specific life stage. [Author] The aim of this report was to provide an assessment to characterize the risk of less-than-lifetime exposure to 3-MCPD (including 3-MCPD fatty acid esters) and GEs via LNS/RUTF in the context of limited food availability. [Author] The thresholds identified herein for concentrations of 3-MCPD and glycidol equivalents in LNS/RUTF products are considered to represent a level of exposure that is of low concern for human health.

Climate change is causing unprecedented damage to our ecosystem. Increasing temperatures, ocean warming and acidification, severe droughts, wildfires, altered precipitation patterns, melting glaciers, rising sea levels and amplification of extreme weather events have direct implications for our food systems. While the impacts of such environmental factors on food security are well known, the effects on food safety receive less attention. The purpose of Climate change: Unpacking the burden on food safety is to identify and attempt to quantify some current and anticipated food safety issues that are associated with climate change. The food safety hazards considered in the publication are foodborne pathogens and parasites, harmful algal blooms, pesticides, mycotoxins and heavy metals with emphasis on methylmercury. There is also, a dedicated section on the benefits of forward-looking approaches such as horizon scanning and foresight, which will not only aid in anticipating future challenges in a shifting global food safety landscape, but also help build resilient food systems that can be continually updated as more knowledge is assimilated. By building a more widespread and better understanding of the consequences climate change has on food safety, it is hoped that this document will aid in fostering stronger international cooperation in making our food safer by reducing the global burden of these concerns.

The Codex Committee on Food Labelling (CCFL) requested scientific advice as to whether certain foods and ingredients, such as highly refined foods and ingredients, that are derived from the list of foods known to cause hypersensitivity can be exempted from mandatory declaration. The objective of this fourth meeting was to expand on the recommendations from the first meeting concerning derivatives of food allergens and establish a framework for evaluating exemptions for food allergens. A pro forma process has been developed and tested against allergen derivatives previously granted exemptions in various countries or regions and found to be effective for consideration in future exemption decisions. The Expert Committee recommends that the process outlined in the pro forma process be used to guide any future development and evaluation of derivative exemptions. Establishment of safety based upon this weight of evidence approach is dependent upon consideration of data quality, outcome of the exposure assessment for all intended ingredient uses (specified for exemption) and review by competent authorities (as needed). When safety is established, exemption can be justified.

This book explores how climate change and disaster risks threaten human security in Asia. Climate change and disaster risks have emerged as major human security challenges in the twenty-first century, and are an imminent “threat multiplier” with the potential to harm the vital core of human life and curtail people’s freedom and ability to live with dignity. Climate change and disaster risks undermine the security of individuals, communities, nations, and the world, considering the increasing trend in the frequency and magnitude of hydro-meteorological disasters and the projections on their future adverse impacts. Despite recent advances in the literature, there is still a major gap in understanding the relationship and linkages between climate change, disaster risks, and human security, particularly as gleaned from the Asian experience. Asia is the world’s most vulnerable region in terms of the quantity and magnitude of impacts from various forms of disaster. At the same time, it has developed a number of innovative responses to address those risks, offering a wealth of experience. Exploring and capitalizing on the Asian perspective, this book provides valuable resource material for students, academics, researchers, policymakers, and development practitioners working in these areas.
