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.
Several species of Dinophysis produce one or two groups of lipophilic toxins: okadaic acid (OA) and its derivatives; or the dinophysistoxins (DTXs) (also known as diarrhetic shellfish poisons or DSP toxins) and pectenotoxins (PTXs). DSP toxins are potent inhibitors of protein phosphatases, causing gastrointestinal intoxication in consumers of contaminated seafood. Forty years after the identification of Dinophysis as the causative agent of DSP in Japan, contamination of filter feeding shellfish exposed to Dinophysis blooms is recognized as a problem worldwide. DSP events affect public health and cause considerable losses to the shellfish industry. Costly monitoring programs are implemented in regions with relevant shellfish production to prevent these socioeconomic impacts. Harvest closures are enforced whenever toxin levels exceed regulatory limits (RLs). Dinophysis species are kleptoplastidic dinoflagellates; they feed on ciliates (Mesodinium genus) that have previously acquired plastids from cryptophycean (genera Teleaulax, Plagioselmis, and Geminigera) nanoflagellates. The interactions of Dinophysis with different prey regulate their growth and toxin production. When Dinophysis cells are ingested by shellfish, their toxins are partially biotransformed and bioaccumulated, rendering the shellfish unsuitable for human consumption. DSP toxins may also affect shellfish metabolism. This book covers diverse aspects of the abovementioned topics—from the laboratory culture of Dinophysis and the kinetics of uptake, transformation, and depuration of DSP toxins in shellfish to Dinophysis population dynamics, the monitoring and regulation of DSP toxins, and their impact on the shellfish industry in some of the aquaculture regions that are traditionally most affected, namely, northeastern Japan, western Europe, southern Chile, and New Zealand.

This book provides an overview of issues associated primarily with food safety, shelf-life assessment and preservation of foods. Food safety and protection is a multidisciplinary topic that focuses on the safety, quality, and security aspects of food. Food safety issues involve microbial risks in food products, foodborne infections, and intoxications and food allergenicity. Food protection deals with trends and risks associated with food packaging, advanced food packaging systems for enhancing product safety, the development and application of predictive models for food microbiology, food fraud prevention, and food laws and regulations with the aim to provide safe foods for consumers. Food Safety and Protection covers various aspects of food safety, security, and protection. It discusses the challenges involved in the prevention and control of foodborne illnesses due to microbial spoilage, contamination, and toxins. It starts with documentation on the microbiological and chemical hazards, including allergens, and extends to the advancements in food preservation and food packaging. The book covers new and safe food intervention techniques, predictive food microbiology, and modeling approaches. It reviews the legal framework, regulatory agencies, and laws and regulations for food protection. The book has five sections dealing with the topics of predictive microbiology for safe foods; food allergens, contaminants, and toxins; preservation of foods; food packaging; and food safety laws.

Marine Molecules from Algae and Cyanobacteria: Extraction, Purification, Toxicology and Applications addresses biomolecules, their roll in living organism, structure elucidation, sources, important characteristics and their industrial applications for educational (academic) and industrial purposes. The book covers all methodologies used in the search of marine natural products, including screening of marine molecules by chemical methods like HPLC, LC-MS/MS, and more. These chemical compounds range from small molecules and enzymes to highly complex secondary metabolites that show bioactivities in physiological systems. Many of these compounds are not commercially available, so the isolation methods of these molecules from microalgae, seaweeds and cyanobacteria is challenging. Because of the complexity of their structure, the total synthesis has been shown to be difficult. Developing protocols to obtain reference standards from natural sources have shown satisfactory results in the chemical industry. The marine environment is a rich but underexploited source of commercially interesting natural products with different applications. Several marine organisms, such as seaweeds, microalgae, sponges, cyanobacteria, ascidians and fungi are sources of natural valuable molecules. - Provides chronological advancements of marine biomolecules, biochemical reactions, and modern industrial applications in the various fields of science and engineering - Highlights well-established research, technology, and applications on marine biomolecules, moves to their rapidly emerging aspects, and then discusses future research directions - Serves as a valuable reference for scientists, chemists, biochemists, nutritionists, pharmacists, and engineers who are searching for modern design and applications of marine molecules
