昨天看到紐西蘭食品衛生局公佈的5ppm,看不太懂,意思好像跟台灣衛生署差不多,
因為產品包裝可能釋出的風險,而根據根據歐盟公佈的TDI值去訂定,
而為何定各5ppm?超過5ppm才會採取行動,那等於許可值和之前衛生署說的好像沒有衝突
只是台灣解釋用2.5ppm 作為分析極限,並當成許可值,而引起反彈?

“Since the identification of the problems in China, food safety authorities
all around the world have been working to identify public health threshold
levels for melamine. We know that the presence of this chemical is part and
parcel of our life today, apparently leaching from plastics and contact
materials during processing and packaging in trace quantities. We also know
that at low levels it causes us no harm. Determining just how high levels
have to be before there is a risk is something we are all struggling with,”
says Dr Geoff Allen, NZFSA Director (Compliance & Investigation).
NZFSA has been in close contact with authorities in Australia, Canada, Europe
and the United States and elsewhere since the issue with melamine
adulteration in China became known.
“Over the past week, our scientists have been exchanging information with
their international colleagues. Last night, the European Food Safety
Authority updated its opinion on the estimated tolerable daily intake (TDI)
of melamine and left it unchanged at 0.5 mg/kg bodyweight (ie, for every kg a
person weighs they can safely consume 0.5 mg every day – for a 20 kg child
this is 10 mg; for a 70 kg adult the safe amount is 35 mg).”
Based on this figure, which is very close to but lower than that of the
United States, NZFSA has adopted a conservative threshold of 5 ppm for most
foods. This means that it has been considered that foods containing up to 5
ppm of melamine do not pose a risk to human health. However for starter
infant formula, this level will be set to the current level of test detection
of 1 ppm.

→ Waitingchen :嗯，就文章的意思來看，他們參考歐盟的TDI，認定5ppm 09/27 12:33
→ Waitingchen :以下的產品對人體健康不致有威脅 09/27 12:34
推 Waitingchen :但對嬰兒奶粉的標準仍維持目前的1ppm以下 09/27 12:35
我不是學化學的,還是有疑問
化工世界沒有純化物,所以無法測出0,是這樣嗎?
器皿怎麼釋出,高溫?曝曬? 有些原料奶粉是紙袋裝的,怎麼釋出?

推 Waitingchen :應該是說，儀器都有偵測極限，樣品裡的濃度低於這個 09/28 01:56
→ Waitingchen :極限，在儀器的眼中，跟0的定義是一樣的。至於紐國 09/28 01:57
→ Waitingchen :的5ppm跟1ppm上限，文中說明是考量容器釋出的污染 09/28 01:59
推 Waitingchen :還有製造過程中，跟有污染的原料接觸混雜 09/28 01:59
→ Waitingchen :（記得高溫跟酸會讓某些塑膠釋出三聚氰胺） 09/28 02:01
→ Waitingchen :總之這個文章的說法，跟衛生署最早的說法是一樣的， 09/28 02:01
→ Waitingchen :後來民眾質疑2.5ppm標準如何訂出，才提到儀器極限 09/28 02:02
