Download or read book Report of the Expert Meeting on Ciguatera Poisoning written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2020-06-01 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phytoplankton blooms, micro-algal blooms, toxic algae, red tides, or harmful algae, are all terms for naturally occurring phenomena that have occurred throughout recorded history. About 300 hundred species of micro algae are reported at times to form mass occurrence, so called blooms. Nearly one fourth of these species are known to produce toxins. Even non-toxic algal blooms can have devastating impacts when they lead to kills of fish and invertebrates by generating anoxic conditions. Some algal species, although non-toxic to humans, can produce exudates that can cause damage to the delicate gill tissues of fish (raphidophytes Chattonella, Heterosigma, and dinoflagellates Karenia, Karlodinium) . Aquatic animals can suffer devastating mortalities, which could lead economical and food losses, and eventually became a food security problem. Of greatest concern to humans are algal species that produce potent neurotoxins that can find their way through shellfish and fish to human consumers where they evoke a variety of gastrointestinal and neurological illnesses (paralytic shellfish poisoning (PSP), amnesic shellfish poisoning (ASP), diarrhoeic shellfish poisoning (DSP), neurotoxic shellfish poisoning (NSP), azaspiracid shellfish poisoning (AZP) and ciguatera fish poisoning (CFP)). Worldwide, ciguatoxins are estimated to cause around 50 000 cases of ciguatera fish poisoning annually; neurological effects may last for weeks or even years and one percent of these cases are fatal . Climate change and costal water over enrichment create an enabling environment for harmful algal blooms, which seem to have become more frequent, more intense and more widespread in the past decades.
Download or read book Emerging Marine Biotoxins written by Ana Gago-Mart´ınez and published by MDPI. This book was released on 2019-08-27 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The emergence of marine and freshwater toxins in geographical areas where they have never been reported before is a concern due to the considerable impact on (sea)food contamination, and consequently, on public health. Several groups of marine biotoxins, in particular tetrodotoxins, ciguatoxins, and palytoxins, are included among the relevant marine biotoxins that have recently emerged in several coastal areas. A similar situation has been observed in freshwater, where cyanobacterial toxins, such as microcystins, could end up in unexpected areas such as the estuaries where shellfish are cultivated. Climate change and the increased availability of nutrients have been considered as the key factors in the expansion of all of these toxins into new areas; however, this could also be due to more intense biological invasions, more sensitive analytical methods, or perhaps even an increased scientific interest in these natural contaminations. The incidences of human intoxications due to the consumption of seafood contaminated with these toxins have made their study an important task to accomplish in order to protect human health. This Special Issue has a focus on a wide variety of emerging biotoxin classes and techniques to identify and quantify them.

Download or read book Marine Toxins written by Dominick Gray and published by Nova Science Publishers. This book was released on 2016 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: In areas where toxic algal blooms occur, the main affected organisms are shellfish, which, because of their high levels of filtration (clearance rate), accumulate high concentrations of nutrients and toxic phytoplankton in their visceral tissue. This accumulation of toxins in shellfish leads to a distribution of these toxins to their different non-visceral tissues. Chapter One of Marine Toxins: Detection Methods, Chemical and Biological Aspects and Health Effects discusses the detection and quantification of lipophilic marine biotoxins by liquid chromatography tandem mass spectrometry from endemic species and gastropods. Chapter Two presents studies which use the similarity analysis of paralytic shellfish poisoning toxins (PSP-toxins) profile patterns to analyze epidemiological linkage of a group of toxins contaminated bivalves collected between years 2004 and 2015. Chapter Three provide an overview of the current status of biomarker use in the assessment of the effects of marine toxins on bivalve mollusks. Chapter Four reviews the latest research on the biological and clinical effects of caulerpenyne.

Download or read book Marine Toxins as Research Tools written by Nobuhiro Fusetani and published by Springer Science & Business Media. This book was released on 2009-01-31 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine organisms produce a wide array of toxins, many of which are not only structurally unusual, but also show potent and interesting modes of action. Since the discovery of tetrodotoxin, a pufferfish toxin, as a potent and selective blocker of Na+ channels in 1964, it has been widely used as a research tool in pharmacological and physiological research. This has led to the identification of a number of important biological functions for Na+ channels. In recent years, much biological research has been carried out at molecular and cellular levels, and therefore selective inhibitors of enzymes and selective antagonist/agonists of receptors and channels have become increasingly important research tools. Accordingly, interest in using such compounds as reagents has increased. Marine toxins are some of the most popular research tools and have already contributed much to our understanding of biological processes and disease mechanisms.
