我只找到歐盟 contam_ej_807_melamine.pdf 文件
http://www.efsa.eu.int/EFSA/efsa_loc...1902098495.htm

歐洲食物安全局將三聚氰胺吸入量訂為 0.5毫克/千克 體重 [tolerable daily intake (TDI) 0.5 mg/kg by weight]
也就是說,每一千克(公斤)體重可以安全地每天吸入 0.5 毫克三聚氰胺,一個 20 公斤兒童每天吸入 10 毫克可視為安全,一個 70 公斤成人則為 35 毫克。

EFSA’s scientists today issued a statement saying that if adults in Europe were to consume chocolates and biscuits containing contaminated milk powder, they would not exceed the TDI (Tolerable Daily Intake) of 0.5 mg/kg body weight, even in worst case scenarios[2].

有點好奇的那個 0.5 mg/kg body 是多少 ppm?

有一個網站是解釋為 1 mg/L 或 1mg/kg = 1 ppm 的話,0.5 mg/kg 不就是 0.5 ppm 了?

不過我是這樣想的,版上有人是學化工或是食品化學的嗎?

那個 1 mg/L 或 1mg/kg = 1 ppm 是否正確?
沒錯,1mg/kg = 1 ppm ,但是那個0.5mg/kg 不是檢驗標準,是歐盟建議的TDI(每日容許吸收量)

在歐盟網頁上,我是沒看到2.5ppm 資訊
但是在英國Food Standards Agency 有看到下列資訊
還有這資訊下面,還有兩封letters 說明上述消息依據來源的連結
有興趣的,自己可以去研究
有人說歐盟網頁沒有2.5ppm 的資訊,但是在英國官方網頁上看到資訊,難道這是英國在造假新聞嗎?



Update on melamine
Friday 26 September 2008


The European Commission has asked EU Member States to carry out checks on all products imported from China that contain over 15% milk.

As part of their normal regime, local authorities at seaports and airports carry out regular checks on imported food to ensure that it meets strict EU food safety requirements.

All products from China containing more than 15% milk as an ingredient, or products where the percentage of milk content cannot be established, will be subject to documentary, identity and physical checks, including laboratory analysis, to determine that any levels of melamine present in the product do not exceed 2.5 mg/kg. Those products with more than 2.5mg/kg will be destroyed.

The Food Standards Agency works with port health authorities and local authorities to ensure EU controls are strictly enforced. There has been a longstanding ban on the import of milk and other products of animal origin from China as controls on the food industry in China do not meet the very strict requirements set in the EU.

At present, we have no evidence of contaminated products in the UK. Should any be found, we will take appropriate action and provide updates online.

The Agency has today written to ports and local authorities across the country to alert them to this new testing regime. The letters can be found at the links below.

The European Food Safety Authority (EFSA) has confirmed that the risk from these composite products (food containing a proportion of milk product) is low.
