Identify toxic seafood

Through the published research work, scientists at the Institute of Oceanography have identified 39 species of seafood in Vietnamese waters carrying toxins (including fish, snails, squid, sea snakes) all capable and once killed many people.

That is not to mention two freshwater fish species also carry lethal toxins. Depending on each species and many other factors, toxins exist, concentrating on different parts of their body or the level of toxins changes with the seasons .

The level of poisoning and death of many of them is also terrible. For example, according to the researchers, the toxicity of marine snakes is more than ten times more toxic than terrestrial poisonous snakes. As for the species of grouper puffer fish, in the season with the highest toxin content (April, October each year), only 100g of its eggs is enough to kill about 200 people.

Or just 100g of eggs or liver of orange puffer fish can also kill 60-70 people. For many types of puffer fish, other goby also with a high concentration of meat, eggs, liver or skin concentration can also kill from many people to several dozen people when eating.

Causing poisoning and killing people as mentioned above of pufferfish mainly through food sources processed from these seafood species .

Therefore, one of the objectives of the study, with the support of the Department of Science and Environment of Khanh Hoa province, about the toxic seafood species in the Vietnamese waters of scientists at the Institute of Hai Hai. Positive school in Nha Trang is aimed at helping many people, especially fishermen; those who work in the maritime profession; naval officers and soldiers; traveler; housewife; food processing chefs and managers . know the morphological characteristics and the characteristics, toxicity . of those toxic seafood to be alert, alert and Be careful to avoid and minimize poisoning poisoning cases, killing people.
