Book Description
The purpose of this manual is to give the reader a foundation of practical knowledge regarding all aspects of Pacific oyster cultivation. It is targeted at new entrants to the market wishing to establish a farm, and existing operators who wish to develop their farms and explore new cultivation techniques. The methodologies described can be applied both to low-tech, low budget, small-scale farming operations and to high-tech, big budget, industrial-scale aquaculture production enterprises. This guide focuses on the functional expertise and technical equipment required to construct and manage an operational farm in the diverse environmental and physical locations in which they can be situated, from the initial stages of finding and selecting a suitable site, to the conclusion of the first production cycle and harvesting the crop. The manual contains a brief introduction which describes the relevance of the species with regards to global aquaculture production figures and how it can form an important part of future food production strategies. Chapter 2 describes the anatomy and biology of Crassostrea gigas and gives an indication as to the environmental conditions in which the species thrives as well as the pathologies and predators that can result in poor health leading to potential mortalities. Chapter 3 deals with all aspects of undertaking a survey of potential oyster farming sites and what data should be collected and examined to assess a site’s suitability, but also which areas are best suited to different cultivation techniques. After this, Chapter 4 introduces the main farming techniques that will be described in detail in the following chapters, which includes off-bottom cultivation, on-bottom cultivation, and suspended cultivation, and gives details of some of the most common cultivation equipment necessary to undertake these operations. The techniques and strategies necessary to procure seed oysters and how to develop them through the nursery stage are also introduced. This includes the basic principles of upwelling, which then leads into Chapter 5, which provides a detailed description of how to build and operate one particular example of a Floating Upwelling System (Flupsy) which is suitable for use in remote but sheltered conditions. Chapters 6, 7 and 8 constitute the main body of the manual and provide an in-depth look into the three major cultivation techniques that this guide concentrates on: “Farming with trestles and bags in the intertidal zone”, “On-bottom cultivation in the intertidal or subtidal zone” and “Offshore longline cultivation”.

Book Description
Globally, there are 3 400 to 4 000 described species of marine microalgae but only 1 to 2 percent are considered to be harmful. Harmful algal blooms (HABs) have significant impacts on food safety and security through contamination or mass mortalities of aquatic organisms. The impacts and mass mortalities of marine species caused by harmful algae are not new and have been recorded for decades. However, there is growing concern that these events will increase due to accelerating global warming, climate change and anthropogenic activities. Indeed, if not properly controlled, aquatic products contaminated with HAB biotoxins are responsible for potentially deadly foodborne diseases and when rapidly growing, HAB consequences include reduced dissolved oxygen in the ocean, dead zones, and mass mortalities of aquatic organisms. Improving HAB forecasting is an opportunity to develop early warning systems for HAB events such as food contamination, mass mortalities, or foodborne diseases. Surveillance systems have been developed to monitor HABs in many countries; however, the lead-time or the type of data (i.e. identification at the species-level, determination of toxicity) may not be sufficient to take effective action for food safety management measures or other reasons, such as transfer of aquaculture products to other areas. Having early warning systems could help mitigate the impact of HABs and reduce the occurrence of HAB events. The Joint FAO-IOC-IAEA technical guidance for the implementation of early warning systems (EWS) for HABs will guide competent authorities and relevant institutions involved in consumer protection or environmental monitoring to implement early warning systems for HABs present in their areas (marine and brackish waters), specifically those affecting food safety or food security (benthic HABs, fish-killing HABs, pelagic toxic HABs, and cyanobacteria HABs). The guidance provides a roadmap for stakeholders on how to improve or implement an EWS for HABs and biotoxins, where appropriate. It is important to note that not all countries and institutions can implement the same level of EWS for HABs, and this guidance is intended mainly for those who seek to broaden existing early warning systems, or who are just beginning to consider putting a system in place.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
Evolving science and debate concerning the benefits and risks of consuming fish have resulted in confusion over the years, and national and international food safety agencies have recognized the need to provide useful, clear and relevant information in this regard to consumers. In October 2023, FAO and WHO held the second Joint FAO/WHO Expert Consultation on the Risks and Benefits of Fish Consumption to analyse new scientific evidence on the matter and draw relevant conclusions and recommendations. The overall conclusions of the exercise show that consuming fish provides energy, protein and a range of other nutrients important for health, and that there are benefits related to fish consumption during all life stages (pregnancy, childhood and adulthood). General population studies show that the benefits and individual effects of fish consumption vary depending on overall diet, the characteristics of consumers, and the fish that is consumed.
