Survey on Toxicity and Label of Dried Dressed Fish Fillet in 1998

由於香魚片最近在國內偶爾會造成食物中毒事件，因此為知台灣市販香魚片之標示和毒性，乃自1998年8月-12月，自基隆、台北、新竹、台中、台南、高雄、宜蘭、台東、澎湖等九地區，共採得58包香魚片，經調查產品名稱、製造日期、食品添加物製造者等標示，發現產品有65%以上均未符合食品衛生法之標示。產品毒性經檢查香魚片364個樣品，若以5 MU／g 檢出界限，則發現4個樣品有毒，有毒檢體發現率為1.1%，毒性最高值為15 MU／g，有毒香魚片中之毒素，經抽出超過濾和層析管精製，粗毒經薄層層析電泳分析和高效能液相層析儀分析，得知毒素含有河魨毒和脫水河魨毒。

Recently, dried dressed fish fillets have been reported as a cause of food poisoning. Hence, 364 samples of 58 packages of these products were collected from 9 counties; Keelung, Taipei, Hsinchu, Taichung, Tainan, Kaohsiung, Ilan, Taitung and Penghu in 1998 and their toxicities and labels were investigated. It was found that over 65% of products had no label listing the product name, manufacturing date, manufacturer, or food additives. Based on the detecting limit of 5 mouse units per gram (MU/g), the frequency of toxicity occurrence in the samples collected from Taiwan markets was 1.1%. The highest toxicity was 15 MU/g. The toxin obtained from toxic samples was partially purified by ultrafiltration and Bio-Gel P-2 column chromatography. Results of analyses by thin-layer chromatography, electrophoresis and high performance liquid chromatography showed that the toxin was composed of tetrodotoxin and anhydrotetrodotoxin. 由於香魚片最近在國內偶爾會造成食物中毒事件，因此為知台灣市販香魚片之標示和毒性，乃自1998年8月-12月，自基隆、台北、新竹、台中、台南、高雄、宜蘭、台東、澎湖等九地區，共採得58包香魚片，經調查產品名稱、製造日期、食品添加物製造者等標示，發現產品有65%以上均未符合食品衛生法之標示。產品毒性經檢查香魚片364個樣品，若以5 MU／g 檢出界限，則發現4個樣品有毒，有毒檢體發現率為1.1%，毒性最高值為15 MU／g，有毒香魚片中之毒素，經抽出超過濾和層析管精製，粗毒經薄層層析電泳分析和高效能液相層析儀分析，得知毒素含有河魨毒和脫水河魨毒。
