一般人都認為吃魚會變聰明，但都忽略了深海魚類體內殘留的汞，有一位3歲小朋友從一歲開始，一天吃兩次魚，結果產生語言發展遲緩的現象，就醫發現體內汞含量超過標準值，醫師就警告，不只小朋友，汞也會讓大人會造成危害，建議深海魚類勿長期過量食用。
魚肉攤前生意超好，民眾都覺得吃魚好，但台北榮總今天發表「食用魚類造成的汞中毒」報告，發現收案門診的患者，其中孩童多語言遲緩等問題，和長期攝食深海魚有關。
醫師表示，一般常見深海魚類，如鯊魚、旗魚、鮪魚和鱈魚，體內含汞量多，吃多對大人小孩都不好。

大人的症狀主要是包括神經的症狀，手抖或者記憶力減退，心血管疾病的機會也會升高。小朋友的症狀就比較多樣化，注意力缺損的一些症狀，包括他過動，然後沒有辦法安靜下來，不能夠專心。
醫師建議，深海魚類一週吃一次就好。
The case of a small child whose development was stunted by mercury poisoning is renewing fears of tainted deep sea fish. Since age 1 the girl ate two servings of fish a day, and, by age 3, faced several speech and other developmental disabilities. Doctors who helped treat her suggest eating no more than a serving of deep sea fish each week.
Business is brisk at this fish stand, with many consumers choosing fish for its health benefits. But a report today from Taipei Veterans General Hospital shows that hidden dangers can linger. It focuses on the case of a young child who, after regularly eating fish, developed several speech impediments.
Dr. Wu Ming-ling says that deep-sea fish such as sharks, sailfish, tuna and cod can be highly contaminated with mercury. Eating too much can be detrimental to the health.

Symptoms in adults are typically associated with the nervous system and can include trembling in the hands and reduced memory, says Wu. (Mercury) can also increase the risk of cardiovascular disease. Children face an even wider range of symptoms, including reduced concentration, hyperactivity, an inability to stay quiet, and poor focus.
Wu recommends just one serving of deep sea fish a week.
