Authorities in the South Korean capital are trying to untangle themselves from a slimy row: how many octopus heads is it safe to eat?
The dish is a firm favourite on the peninsula – for its apparent aphrodisiac qualities.
In September, the Seoul city government enraged restauratuers and the fishing industry when it announced octopus heads contained hazardous amounts of cadmium, a carcinogen that poisons the liver and kidneys.
It advised against eating more than two heads a day.
Perhaps if they were deep-fried in batter?
