※ 引述《noone (十之八九)》之銘言：
: 不完全是這樣的
: 事實上科學界還無法確定蛋中致死性的沙氏桿菌的來源
: 請注意我說的是蛋中
: 因為可能會蛋黃裡含有這種細菌
: 但蛋殼上和蛋白卻沒有
: 科學家還無法確定蛋黃中的細菌是哪裡來的
: 但基本上懷疑是母雞帶的
: 大家可以參考一下這篇文字
: 相當簡單好讀
: 摘錄自http://www.fda.gov/bbs/topics/CONSUMER/CON00072.html
: 是美國政府機關的網站
: 如果還有疑慮
: 不防以Salmonella enteritidis 為關鍵字查得更多資料
: 在這篇文章的前半段
: 則列述美國歷年來的死亡病例
: How Does Contamination Occur?
: No one knows how some intact eggs become contaminated with Salmonella
: enteritidis. Poultry researchers, however, suggest that the egg yolk
: becomes infected before the shell forms.
: In fact, Charles Benson, Ph.D., of the University of Pennsylvania, says that
: in his experiments the bacteria were found not in the white, as when
: organisms penetrate the egg shell, but only in the yolk. This occurred even
: though Benson added iron to the white to encourage the bacteria to grow in
: the albumen, which has antibacterial properties.
: Madden believes that in the past 10 years a new strain of Salmonella
: enteritidis that can live in chickens may have evolved. Other researchers
: are finding that Salmonella enteritidis bacteria migrate from the yolk to
: the white of the egg, where they can survive up to 12 hours. However, it is
: in the yolk where the bacteria multiply and thrive.
: These and other findings, such as ovarian infections in egg-laying chickens,
: have led to the concept of transovarian transmission. According to this
: theory, the infection occurs first in the chicken and is transferred to the
: egg before the shell is formed.
: Researchers also speculate that the infection may be passed from bird to
: bird in the same flock. For instance, Madden notes that several birds might
: pick up Salmonella enteritidis from the droppings of rodents and sparrows
: (known carriers of the organism) and spread it among the others. There are
: also reported cases, Madden adds, of workers picking up the bacteria on
: their clothing and transmitting Salmonella from one chicken house to another.
: Only after scientists understand how Salmonella is transmitted will they
: know how to control it. Right now the proposed solution is a long-range
: plan to prevent spread of the disease by testing flocks and replacing
: infected ones.
建議版主把上文M起來
除非版主覺得英文文章不適合放在精華區
我點進上文所附網頁看了一下
那篇文章還有安全儲存及烹調方式
應該足以解答大部分人的疑惑
未熟蛋會不會致命這個問題我記得很久以前就出現過
還有人信誓旦旦的說salmonella "只會存在於蛋殼外" 。。。
所以我也貼了一篇和上文類似的文章
剛去看了一下精華區似乎也沒有被收錄
所以為了避免同樣的問題一再被提出
建議版主將上文收錄到精華區
如果還有其他疑問者
此類文章去U.S. national library of Medicine隨便搜尋一下就一大堆
以上
