於我心有"七七"焉

相信大家最近應該都是聞奶色變吧！

「聯合新聞網」之前有這則新聞：
三聚氰胺容許量》紐國5ppm 歐盟2.5ppm
更新日期:2008/09/28 07:10 記者施靜茹／台北報導

這是政府後來改變對於三聚氰胺標準的根據，
歐盟和紐西蘭的食品安全官方網站，昨天都緊急貼出三聚氰胺容許量最新公告，其中歐盟將容許量訂為二點五ppm（百萬分之一濃度），衛生署雖已初步掌握，但不敢告訴台灣民眾。

而英國食品標準局的網站，這兩天也在網頁發布歐盟食品安全委員會有關三
聚氰胺容許量，也是訂為二點五ppm，並指歐洲販售乳製品含三聚氰胺風險很低。

這是咱們的「新聞報導」，
如果要讀全文，可以連上http://tw.news.yahoo.com/article/url/d/a/080928/2/16p70.html

但是，事實是這樣嗎？

這是馬政府所謂的「根據」嗎？

有朋友提供下面的資訊，
大家自己去判斷一下！

一〉根據紐西蘭政府網站，紐西蘭幼童單日危險量為 1 ppm：
http://www.nzfsa.govt.nz/publications/media-releases/2008/26-sep-melamine-response-update.htm
"However for starter infant formula, this level will be set to the
current level of test detection of 1 ppm."

二〉歐盟食品管理局網站公佈的TDI〈每人每日容忍量〉標準依然 0.5 ppm。請注意，這是每人每日容忍量〈請見下面說明〉，不是產品容許含量上限：
http://www.efsa.eu.int/EFSA/efsa_locale-1178620753812_1211902098433.htm
"High levels of melamine can primarily affect the kidneys. EFSA
applied the TDI of 0.5 mg/kg body weight for melamine in a specific
case of contamination in 2007[3]."
(mg/kg = ppm)

三〉英國食品標準局的網站，原文在：
http://www.food.gov.uk/news/newsarchive/2008/sep/melamine
裏面的確提到，來自中國牛奶成份超過15%的產品必需受檢，三聚氰胺成份超過 2.5mg/kg的產品必須被銷毀。
"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."


可是，事情就這樣了嗎？請注意，後面都還有一段：
"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."
由於中國的食品工業不符合歐盟的規定, 所以來自中國的牛奶及動物製品已經長期被禁止進口。

歐盟是全面禁止中國乳製品的。

歐盟網站上的容許值只是說，在這樣〈不知危害有多大〉的危機發生之下，你吃多少大概不會立刻死，可是長期危害還是不清楚。請見該文件中：
[3] Because there is uncertainty with respect to the time scale for
development of kidney damage, EFSA used the TDI of 0.5 mg/kg body
weight which is protective for exposure over a lifetime in considering
possible effects of exposure to melamine over a relatively short
period, such as might occur with repeated consumption of melamine
contaminated products

而且強調，在不完全的數據下，歐盟是用最壞的〈高劑量〉情況，做最壞的推測。歐盟食品管理局強調，目前並不知道這樣的三聚氰胺污染是否會在歐洲發生〈因為中國乳製品在歐洲全面禁止〉。
In the absence of available data for contaminated milk powder, EFSA
also used the highest value of melamine, reported in Chinese infant
formula as a basis for worst case scenarios. EFSA stressed that it is
not known at the moment whether such theoretical high level exposure
scenarios could occur in Europe.
