Hong Kong 消委會 investigated 23 different brand of smoked dried seafood. They found that 9 brand of dried squid have contained arsenic (俗稱砒霜的重金屬「砷」) more than the maximum permissible concentration (MPC). Eating too much arsenic will cause skin and liver damage.
This high level of arsenic is most likely caused by squids living in poluted water.
消委會 also found that dried pork and dried beef have a high level of preservatives (苯甲酸、山梨酸). Eating too much will damage health too!
This is another example of human committing long term suicide!! :(
Human polutes water -> Fishes/squids living in water get poisoned -> Human eats poluted seafood -> Human get poisoned and eventually dies
