Poisonous Cadmium Found in Octopus Heads
If you're a fan of octopus heads for their nutritional benefits you may want to think again.
Dangerous levels of the heavy metal cadmium were found in the heads of long-legged and regular octopuses sold in the capital.
Last month, Seoul officials conducted tests on 14 types of mollusks and 14 types of fish sold in the city, and the results were alarming.
Over 29 milligrams of cadmium were found in frozen long-legged octopus heads imported from China an amount 14 times higher than the permitted level.
Domestic octopuses had up to 31 milligrams of the poisonous metal concentrated in each head.
Cadmium is a carcinogen that also poisons the liver and kidneys.
Officials suggest completely removing any residual ink and internal organs before eating octopus heads.
