Fugu fish soup leads to mass poisoning in Far East
The culprit is the fugu fish – a traditional and popular Japanese delicacy.
The catch is you have to cook it very carefully because just one fish contains a poison capable of killing over 30 people. In Japan, only very experienced, specially trained cooks are allowed to dress fugu.
Fugu fish are not usually found off Vladivostok, but the warm summer saw their numbers grow.
Hungry anglers took it upon themselves to make what they thought would be a tasty fish soup.
There are more than 20 types of fugu, but it takes an expert eye to know which ones will not leave you clutching your stomach, or even worse.
