“…In Hong Kong, on the other hand, poisonings are generally seen among fishermen, as it is forbidden to sell pufferfish in the market, and only non-toxic cultured pufferfish prepared by licensed masters in restaurants and imported from Japan are allowed to be consumed [110,148]. In addition, many poisoning cases have also been reported in countries where pufferfish and other marine species containing TTX are native, such as Thailand [149,150], Taiwan [90,151,152], Cambodia [153], South Korea [154][155][156][157], Vietnam [130,158], Malaysia [159,160], Bangladesh [109,[161][162][163], Indonesia [164], Singapore [165], and India [166].…”

“…Two cases of poisoning were also reported in Italy, but these cases originated from imported Monkfish [183,184]. native, such as Thailand [149,150], Taiwan [90,151,152], Cambodia [153], South Korea [154][155][156][157], Vietnam [130,158], Malaysia [159,160], Bangladesh [109,[161][162][163], Indonesia [164], Singapore [165], and India [166]. Until recently, TTX was believed to be confined to East Asia, but recent studies have shown that fish containing the toxin have been found in other regions of the Pacific and the Indian Ocean, as well as the Mediterranean Sea [3].…”

An Updated Review of Tetrodotoxin and Its Peculiarities

Tetrodotoxin (TTX) is a crystalline, weakly basic, colorless organic substance and is one of the most potent marine toxins known. Although TTX was first isolated from pufferfish, it has been found in numerous other marine organisms and a few terrestrial species. Moreover, tetrodotoxication is still an important health problem today, as TTX has no known antidote. TTX poisonings were most commonly reported from Japan, Thailand, and China, but today the risk of TTX poisoning is spreading around the world. Recent studies have shown that TTX-containing fish are being found in other regions of the Pacific and in the Indian Ocean, as well as the Mediterranean Sea. This review aims to summarize pertinent information available to date on the structure, origin, distribution, mechanism of action of TTX and analytical methods used for the detection of TTX, as well as on TTX-containing organisms, symptoms of TTX poisoning, and incidence worldwide.

A fatal neurotoxic poisoning case happened in Khanh Hoa province in 2020 after eating a certain number of marine gastropods, later identified as Nassarius glans, one of the common marine gastropods in Vietnam. As the remaining causative food in the incident, 62 specimens were collected to examine tetrodotoxin toxicity individual variation and frequency of toxic specimens by using HILIC/MS-MS analysis. 100% of studied specimens exhibited toxicity (556 ± 821 MU/g) beyond the regulatory level of consumption (10 MU/g) for puffer(fish) recommended in Japan and extensive variation (18–4,046 MU/g). The result pointed out that only 5 g of soft tissue from N. glans (equivalent to 2–3 specimens) containing maximum toxicity detected in the present study may cause human death if consumed. Fhe first time, this study identified TTXs in the gastropods as a causative toxin in the poisoning in Vietnam. Moreover, 65.5% of studied specimens with high toxicity higher than 100 MU/g, including 16.1%, showing extremely high toxicity (> 1,000 MU/g). The results suggested that this gastropod is quite dangerous for human consumption and should be alerted to public awareness.
