※ 引述《noone (十之八九)》之铭言： : 不完全是这样的 : 事实上科学界还无法确定蛋中致死性的沙氏杆菌的来源 : 请注意我说的是蛋中 : 因为可能会蛋黄里含有这种细菌 : 但蛋壳上和蛋白却没有 : 科学家还无法确定蛋黄中的细菌是哪里来的 : 但基本上怀疑是母鸡带的 : 大家可以参考一下这篇文字 : 相当简单好读 : 摘录自http://www.fda.gov/bbs/topics/CONSUMER/CON00072.html : 是美国政府机关的网站 : 如果还有疑虑 : 不防以Salmonella enteritidis 为关键字查得更多资料 : 在这篇文章的前半段 : 则列述美国历年来的死亡病例 : 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. 建议版主把上文M起来 除非版主觉得英文文章不适合放在 我点进上文所附网页看了一下 那篇文章还有安全储存及烹调方式 应该足以解答大部分人的疑惑 未熟蛋会不会致命这个问题我记得很久以前就出现过 还有人信誓旦旦的说salmonella "只会存在於蛋壳外" 。。。 所以我也贴了一篇和上文类似的文章 刚去看了一下似乎也没有被收录 所以为了避免同样的问题一再被提出 建议版主将上文收录到 如果还有其他疑问者 此类文章去U.S. national library of Medicine随便搜寻一下就一大堆 以上 --
