衛生署：狂牛症不會感染乳品

[stockk]

　2012-04-26 11:48 新聞速報 【中央社】


衛生署副署長蕭美玲今天表示，世界衛生組織等單位發表的相關文件認為，狂牛症的變異性蛋白不會進入牛乳中，所以美國乳牛罹患狂牛症不會感染乳製品。

　中國國民黨立法院黨團書記長徐耀昌、首席副書記長吳育昇、立委紀國棟上午召開記者會，邀請蕭美玲、行政院農業委員會副主任委員王政騰出席。

　美國乳牛傳出罹患狂牛症；蕭美玲表示，過去以肉骨粉添加在牛飼料中，造成狂牛症，但牛飼料禁用肉骨粉後，狂牛症病例已經逐年下降；美國自1997年起，牛飼料也已經禁用肉骨粉。

　蕭美玲說，衛生署將加強境外管理，每年也會與農委會及專家學者進行美國牛肉的工廠檢查。

　吳育昇問到，美國乳牛罹患狂牛症，會不會影響乳品品質？蕭美玲說，世界衛生組織等單位發表的相關文件認為，狂牛症的變異性蛋白不會進入到牛乳中，所以美國乳牛罹患狂牛症，不會感染乳製品。

　王政騰說，將明確要求美國提供這次案例完整的流行病學調查，並進一步檢視美國對狂牛症的監測與管控機制確不確實，未來也將加強在美國的查廠動作。1010426

英國羊隻爆發感染類似狂牛病(牛海綿狀腦病, BSE)，為避免罹患腦部病變疾病，英國食品標準局建議民眾減少食用羊肉、山羊肉及羊奶製品，可以降低被感染的風險，但不需要全面停止食用。同時建議歐盟委員會儘速推出新的食品商標法，凡是含有羊肉的食品都應該明確標示。

英國食品標準局官員坦承，如果消費者食用感染BSE疾病的羊肉，不能排除也被感染的可能。羊肉占英國民眾總肉品消費量的1/4，每年英國食用約8000噸羊肉、價值約八億英鎊。羊肉被廣泛使用在肉派、咖哩食譜、肉餡包及微波餐等，部分臘腸及道地蘇格蘭菜Haggis都使用羊的內臟，如果食用的羊隻已感染BSE疾病，消費者被感染的風險也提高。

In response to the USDA’s claim, yesterday, that milk from the recently identified mad dairy cow poses no health threat, a skeptical examiner did some perusal of the scientific literature.

A 2011 report in the online journal PLoS One, by a group of UK researchers (Everest et al.), states that the infectious prion protein responsible for mad cow disease (Bovine spongiform encephalopathy, BSE)

“can be detected in a wide range of viscera and body fluids, including muscle, saliva, blood, urine, and milk.”



在回應美國農業部的昨天說法，，從最近發現的狂牛症的奶牛的牛奶不會產生健康威脅，持懷疑態度的檢驗員做了一些科學文獻審閱。

一篇線上雜誌 2011 報告 :英國研究人員宣稱，狂牛症的的傳染性蛋白質

“可以在廣泛的內臟和體液中，包括肌肉，唾液，血液，尿液和牛奶。檢測到”

‘’Conclusions/Significance

In view of a recent study showing evidence of prion replication occurring in the mammary gland of scrapie infected sheep suffering from mastitis, the appearance of PrPC in milk implies the possibility that milk of TSE-infected animals serves as source for PrPSc.‘’

[woodatwan]

‘’Granted, prion diseases are vastly different from HIV. The risk from milk does appear to be much smaller than from eating beef or cattle organ tissues. Nonetheless, a British BSE expert has pointed out that at least one human case suggests passage of prions in milk. A Japanese woman dying of CJD was found to have the infectious agent in her colostrum (the type of breast milk made in the initial days following delivery).51 Milk has been under suspicion in established medical circles. It was one of the products targeted when the United Kingdom was beginning to recognize the magnitude of the mad cow problem. ‘’

‘’Scrapie can be transmitted to lambs through milk, according to new research. The study provides important information on the transmission of this prion-associated disease and the control of scrapie in affected flocks. Scrapie is a fatal neurodegenerative disease of sheep and goats. Clinical signs include itchiness, head tremor, wool loss and skin lesions as well as changes in behaviour and gait.‘’

[stockk]

A 2009 article in Prion by a second group of UK researchers (Gough et al.) describes a method that offers “exquisite sensitivity for the detection of prions” from milk of apparently healthy sheep showing no signs of illness but obviously infected.

在2009年由英國第二組研究人員的文章。介紹了一種方法可以提供“精妙的靈敏度的由乳汁檢測出PRION蛋白”顯示健康沒有疾病的跡象的羊明顯感染到了。

‘’Prion Disease Spreads in Sheep Via Mother's Milk‘’

‘’Transmission of prion brain diseases such as bovine spongiform enecephalopathy (BSE) -- also known as mad cow disease -- and human variant Creutzfeldt-Jakob disease (vCJD) is generally attributed to the consumption of the brain or organ meat of infected animals but new research demonstrates lambs exposed to milk from prion-infected sheep with inflamed mammary glands can develop prion disease as well. The research, which is published in the January 2011 issue of the Journal of Virology, has major implications for human and livestock health.‘’

‘’Study finds prion proteins in milk‘’

[stockk]

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1762385/

Prions are known to cause transmissible spongiform encephalopathies (TSE) after accumulation in the central nervous system. There is increasing evidence that prions are also present in body fluids and that prion infection by blood transmission is possible. The low concentration of the proteinaceous agent in body fluids and its long incubation time complicate epidemiologic analysis and estimation of spreading and thus the risk of human infection. This situation is particularly unsatisfactory for food and pharmaceutical industries, given the lack of sensitive tools for monitoring the infectious agent.

有越來越多的證據顯示，PRION也存在於體液(牛奶是體液的一種). PRION 透過血液傳播是可能的

美國乳牛染瘋牛症　引發消費者對牛奶疑慮

http://www.chinareviewnews.com 2012-04-26 17:18:33


　　中評社香港4月26日電／美國第4例瘋牛症是一頭乳牛，引發消費者對牛奶疑慮；衛生署認為牛奶不會傳染瘋牛症，學者卻不以為然，認為牛羊的乳汁都被發現瘋牛症前驅物質，台灣對奶品的要求應該更嚴格。

　　中央社報道，曾參與瘋牛症風險評估的高雄長庚醫院榮譽副院長、神經內科醫師陳順勝指出，2007年瑞士科學家發展出更靈敏的檢驗工具，首次可在人奶、牛奶及羊奶中偵測到瘋牛症“普利昂”蛋白的前驅物PrPC，甚至超高溫處理後，此前驅物僅能減少一部分，不能徹底消滅。

　　陳順勝表示，2009年英國科學家更發現，羊搔症病羊發生乳腺炎時，可發現羊奶內有普利昂病蛋白。

　　他說，先前美國海綿狀腦病諮詢委員處等單位主張牛奶安全，歐盟與世界衛生組織也把牛奶、初乳與乳腺的組織歸類為無法偵測出瘋牛症感染力的類別；然而，檢驗工具的突破及最新發現，他主張，“對奶品的要求不得不更嚴格”。

　　新光醫院腎臟科主治醫師江守山指出，造成瘋牛症的普利昂蛋白質，與正常神經系統的蛋白質結構幾乎相同，差別只在於蛋白質折疊的方式略微差異，由於島內的檢驗能力有限，台灣應以更嚴格標準把關牛肉及乳製品的安全。

　　江守山說，有研究認為某些傳統庫賈氏病患者，其實是普利昂潛伏感染的新型庫賈氏病（俗稱人類的瘋牛症），因為年紀較大、症狀不典型、缺乏腦組織解剖鑑定，才被錯誤歸類；台灣民眾沒有死後解剖的習俗，卻在開放美牛進口後，傳統庫賈氏病案例大增，應該進一步探究原因。

''衛生署副署長蕭美玲今天表示，世界衛生組織等單位發表的相關文件認為，狂牛症的變異性蛋白不會進入牛乳中，所以美國乳牛罹患狂牛症不會感染乳製品。''

她也說了狂牛症的變異性蛋白不會進入牛乳中，但現在明明就在牛奶偵測出prion。（‘’There is increasing evidence that prions are also present in body fluids and that prion infection by blood transmission is possible‘’,''at least one human case suggests passage of prions in milk.''）

[woodatwan]

''Both humans and animals were banned from consuming an infected cow's milk. Unfortunately, as we have already noted, animals are infected with the BSE prion long before they manifest any symptoms. When infected symptom-free cows are milked, their milk is mixed in collection tanks with milk from healthy cows. If the prion is present in milk, it could theoretically contaminate the whole collection tank. Pasteurization cannot destroy prions, so that process provides no consolation. Although at this time it cannot be stated for certain that milk can transmit a prion-related disease, many are wondering: is it worth taking the chance?''

''Prions are secreted in milk from clinically normal scrapie-exposed sheep.''

''These data indicate the secretion of prions within milk during the early stages of disease progression and a role for milk in prion transmission''

‘’Secretion of Prions within Milk

Whether prion infectivity could be contained within milk has been debated for many years and previous bioassay or epidemiol- ogy data indicated that ruminant milk did not harbor prions.49-52 However, several studies in recent years have demonstrated unequivocally the presence of prions within ovine milk from scrapie-infected sheep.‘’

WHO 2002 年的一篇文章

Milk and milk products are considered safe.

但是這是有前提的，不是只有這一句

Tallow and gelatin are considered safe if prepared by a manufacturing process which has been shown experimentally to inactivate the transmissible agent and, if prepared from specifically identified tissues, or from cattle without risk of exposure to BSE.

不曉得衛署是不是斷章取義

某些 infection disease 的 route 感覺都是ever-changing'

某些 infection disease 的 route 感覺都是ever-changing'

今天推翻昨天 明天推翻今天 是常有的事

那多是因為 ORIGION UNDEFINITE 而且 當時這ROUTE就有很多爭論

醫學還沒見過像PRION在體液.牛奶中多次被發現狀況 而 FOLLOW UP 的研究團隊只要設備夠靈敏 都能產生同樣結果

這樣肯定答案的還會被的被推翻說 PRION 不存在於牛奶中

況且這是 DEFINITE FINDING 不是 ROUTE

今天除了台灣衛生署 還沒看到哪個先進國家敢說牛奶不會有 PRION 蛋白

美國農業部的聲明已經被美國消費者協會攻擊. 畢竟他要賣牛肉.說謊是可以理解的

如果哪天被推翻 中華民國衛生署醫定能獲得中華民國史上第一個諾貝爾醫學獎

沒被推翻 也應該獲得美牛肉說謊推廣獎的首獎.. 由美國狂牛症牛肉協會頒獎.
~~~~~以獎勵全世界 第一個為賣美國牛肉不惜錢騙自己人民的狗腿外國政府 ~~~~~

[rickspringfield]

有solid evidence proved 那一個case是經由喝牛奶
被確定感染的嗎
小的孤陋寡聞 有嗎 ?
如果有 那所謂的infection route 或許才能被established 吧

找到infection agent 跟transmission 還有距離吧

其實覺得感染性已經很大了 but please give me one case report

至於這種政府 What else can i say
