“…The authors also found 10 times higher concentrations of MC-dmLR in the viscera and, therefore, complete removal of the visceral part of these snails during food processing was advised. Other targeted MCs variants (dm-RR, MC-RR, MC-YR, dm-LR, MC-LR, MC-LY, MC-LW, MC-LF) and NODs were not detected in the analyzed Mollusca [152]. In humans, a cross-sectional study included 5493 individuals (southwest China) found an association between renal-function impairment and MC-LR exposure.…”

Cyanotoxins have gained global public interest due to their potential to bioaccumulate in food, which threatens human health. Bloom formation is usually enhanced under Mediterranean, subtropical and tropical climates which are the dominant climate types in developing countries. In this context, we present an up-to-date overview of cyanotoxins (types, toxic effects, analysis, occurrence, and mitigation) with a special focus on their contamination in (sea)food from all the developing countries in Africa, Asia, and Latin America as this has received less attention. A total of 65 publications have been found (from 2000 until October 2021) reporting the contamination by one or more cyanotoxins in seafood and edible plants (five papers). Only Brazil and China conducted more research on cyanotoxin contamination in food in comparison to other countries. The majority of research focused on the detection of microcystins using different analytical methods. The detected levels mostly surpassed the provisional tolerable daily intake limit set by the World Health Organization, indicating a real risk to the exposed population. Assessment of cyanotoxin contamination in foods from developing countries still requires further investigations by conducting more survey studies, especially the simultaneous detection of multiple categories of cyanotoxins in food.

“…These cyanotoxins were mainly distributed in temperate and tropical coastal areas of Asia, as well as inland lakes and rivers in various countries. Among them, MCs are the most widely distributed, which have been reported in China [123,124,125,126], Japan [127], Korea [128], Bangladesh [129], Singapore [130], Saudi Arabia [131], India [132], Philippines [133], Thailand [134], Vietnam [135,136], Israel [137] and Turkey [138]. CYNs and their homologues were mainly distributed in China [125,139], Japan [140], Saudi Arabia [141], Vietnam [142], Thailand [134,143], Israel [144] and Turkey [145].…”

The widespread distribution of cyanobacteria in the aquatic environment is increasing the risk of water pollution caused by cyanotoxins, which poses a serious threat to human health. However, the structural characterization, distribution and identification techniques of cyanotoxins have not been comprehensively reviewed in previous studies. This paper aims to elaborate the existing information systematically on the diversity of cyanotoxins to identify valuable research avenues. According to the chemical structure, cyanotoxins are mainly classified into cyclic peptides, alkaloids, lipopeptides, nonprotein amino acids and lipoglycans. In terms of global distribution, the amount of cyanotoxins are unbalanced in different areas. The diversity of cyanotoxins is more obviously found in many developed countries than that in undeveloped countries. Moreover, the threat of cyanotoxins has promoted the development of identification and detection technology. Many emerging methods have been developed to detect cyanotoxins in the environment. This communication provides a comprehensive review of the diversity of cyanotoxins, and the detection and identification technology was discussed. This detailed information will be a valuable resource for identifying the various types of cyanotoxins which threaten the environment of different areas. The ability to accurately identify specific cyanotoxins is an obvious and essential aspect of cyanobacterial research.

“…For example, many drinking water treatments in Vietnam apply pre-chlorination as an algaecide. However, cyanobacterial cell's membrane can be severely disrupted by chlorine, leading to cell lysis and extracellular cyanotoxins being liberated into drinking water [121]. The combination of treatment techniques can be determined by the quality of the water source.…”

Purpose of ReviewCyanobacteria, commonly known as blue-green algae, are often seen as a problem. Their accumulation (bloom) in surface water can cause toxicity and aesthetic concerns. Efforts have been made in preventing and managing cyanobacterial blooms. By contrast, purposeful cultivation of cyanobacteria can create great opportunities in food, chemical and biofuel applications. This review summarises the current stage of research and the socio-economic impacts associated with both the problems and opportunities induced from the presence of cyanobacteria in surface water. Recent FindingsInsightful knowledge of factors that trigger cyanobacterial blooms has allowed for the development of prevention and control strategies. Advanced technologies are utilised to detect, quantify and treat cyanobacterial biomass and cyanotoxins in a timely manner. Additionally, understanding of cyanobacterial biochemical properties enables their applications in food and health industry, agriculture and biofuel production. Researchers have been able to genetically modify several cyanobacterial strains to obtain a direct pathway for ethanol and hydrogen production.
