年初，美國頗有成就和頗有名氣的植物科學家頓·胡伯博士給美國農業部部長發函，說明了轉基因作物的危害風險，其中包括導致不育等危害。胡伯博士不但是學界科學家，而且是美國軍方科研專家，還是美國農業部植物疾病恢復部門的科學家，對美國轉基因作物的來龍去脈、作用影響和許多秘密是最知情者之一，因而，他的披露轉基因作物危害風險的信件在美歐社會引起強烈反響。

消息披露后，一些轉基因利益商用學者打出“科學人士”的旗號，先是說那封信件不存在、然后又是骨頭里挑刺一般、試圖詆毀那封信的內容。在國內，同樣，一些“挺轉幫”照貓畫虎也那么說。于是，有些網友來信詢問那封信的真實性等問題。

我做的查詢結果：今年三月，美國農業部收到公民依照信息公開法所做的查詢，在回復中確認胡伯博士發給美國農業部長的信件屬實。那之前之后，路透社等歐美媒體報道說，去年年底，美國環保部門對胡伯博士信件所提出的同類問題展開相關轉基因作物的重新調查審核；因工作還處在開始階段，所以，該部門目前還不能發布任何公告公文。

美國農業部確認胡伯博士信件屬實的公告文字原文如下：

USDA-FOIA. 
Case Number: 11-316. Date Received: 10-Mar-11.
Requesting: 
3.) documents and memoranda produced by Secretary Tom Vilsack's office, the USDA, and APHIS personnel pertaining to Dr. Don Huber's January 16th letter to Secretary Vilsack. APHIS deregulated Roundup Ready glyphosate-tolerant GT alfalfa seed (Docket No. APHIS-2007-0044) on Jan. 27th, after Secretary Vilsack received a letter in which Dr. Huber, the APS Coordinator for the USDA National Plant Disease Recovery System (NPDRS), recommended that APHIS continue regulating any GT seed strains until the USDA completes an investigation into a newly discovered pathogen. Requesting any documents and memoranda that include information from any portion of Dr. Huber's letter, as well as any documents containing discussion or analysis of Dr. Huber's positions and recommendations as stated in the letter.

我的補充看法：

[1] 就胡伯博士的信件，孟山都公司做了“我們沒發現危害”云云的聲明。然而，孟山都公司自己的食堂是搞天然食品而避免轉基因食品的，即他們是知道轉基因食品的危害風險的。
同樣，中國農業官員有機關食堂規章制度，保障他們和他們的家屬子女吃的是天然食品和避免轉基因食品；可是，他們卻編造各種假話謊言、欺上瞞下、要全國民眾吃他們不吃的轉基因食品。更有甚者，他們動用國家資金搞所謂“公關”，雇用一些輿論槍手，對反對和拒絕轉基因食品的人搞惡毒攻擊、政治誣告和造謠誹謗，甚至還搞黑客攻擊和騷擾等活動，完全沒了起碼的國家機關的樣子。一些負責官員和媒體大談社會誠信，卻對農業官員為利坑民的嚴重違法亂紀的行為是置之不理甚至放縱，還竭力封殺有關轉基因危害風險的闡明。

[2] 美國官方確認屬實的胡伯博士信件清楚說明了轉基因作物的危害風險。如此，金龍魚之案就應該有個明確了結：郭成林所言完全屬實，應立即無罪釋放。--- 且不說轉基因如何，有消費者不喜歡某產品和批評某產品，就把消費者當作罪犯一樣抓了銬起來、還搞判刑；看看世界地圖，有哪個國家的公司和法庭是如此荒唐做事的？！如此推銷，可見轉基因食品是壞東西，不然，為啥要用暴力強迫民眾接受呢？消費者權益和公民權益的安全還有起碼保障嗎？

[3] 效益風險分析并行（BR分析），是通用所有領域的基本原則。在軍方，只說我情而瞞報虛報敵情、是要上軍事法庭甚至可能被處死的；在衛生領域，瞞報虛報疫情是犯罪行為、是要嚴懲不怠的；在財經金融領域，只說如何賺錢而不說投資風險的經理代理，是要被公司解雇開除的。如此，為什么在轉基因食品領域，就只說能賺多少錢的經濟效益、而不說甚至不許說其對人類健康和生態環境等各方面的嚴重危害風險呢？中國的民眾的生命安全和后代安全、中國的國土農田和生態安全，難道就是那么便宜、那么沒價值嗎？

The Honorable Thomas Vilsack，
United States Secretary of Agriculture。

Dear Secretary Vilsack:

A team of senior plant and animal scientists have recently brought to my attention the discovery of an electron microscopic pathogen that appears to significantly impact the health of plants, animals, and probably human beings. Based on a review of the data, it is widespread, very serious, and is in much higher concentrations in Roundup Ready (RR) soybeans and corn—suggesting a link with the RR gene or more likely the presence of Roundup. This organism appears NEW to science!

This is highly sensitive information that could result in a collapse of US soy and corn export markets and significant disruption of domestic food and feed supplies. On the other hand, this new organism may already be responsible for significant harm (see below). My colleagues and I are therefore moving our investigation forward with speed and discretion, and seek assistance from the USDA and other entities to identify the pathogen’s source, prevalence, implications, and remedies.

We are informing the USDA of our findings at this early stage, specifically due to your pending decision regarding approval of RR alfalfa. Naturally, if either the RR gene or Roundup itself is a promoter or co-factor of this pathogen, then such approval could be a calamity. Based on the current evidence, the only reasonable action at this time would be to delay deregulation at least until sufficient data has exonerated the RR system, if it does.

For the past 40 years, I have been a scientist in the professional and military agencies that evaluate and prepare for natural and manmade biological threats, including germ warfare and disease outbreaks. Based on this experience, I believe the threat we are facing from this pathogen is unique and of a high risk status. In layman’s terms, it should be treated as an emergency.

A diverse set of researchers working on this problem have contributed various pieces of the puzzle, which together presents the following disturbing scenario:

Unique Physical Properties

This previously unknown organism is only visible under an electron microscope (36,000X), with an approximate size range equal to a medium size virus. It is able to reproduce and appears to be a micro-fungal-like organism. If so, it would be the first such micro-fungus ever identified. There is strong evidence that this infectious agent promotes diseases of both plants and mammals, which is very rare.

Pathogen Location and Concentration

It is found in high concentrations in Roundup Ready soybean meal and corn, distillers meal, fermentation feed products, pig stomach contents, and pig and cattle placentas.

Linked with Outbreaks of Plant Disease

The organism is prolific in plants infected with two pervasive diseases that are driving down yields and farmer income—sudden death syndrome (SDS) in soy, and Goss’ wilt in corn. The pathogen is also found in the fungal causative agent of SDS (Fusarium solani fsp glycines).

Implicated in Animal Reproductive Failure

Laboratory tests have confirmed the presence of this organism in a wide variety of livestock that have experienced spontaneous abortions and infertility. Preliminary results from ongoing research have also been able to reproduce abortions in a clinical setting.

The pathogen may explain the escalating frequency of infertility and spontaneous abortions over the past few years in US cattle, dairy, swine, and horse operations. These include recent reports of infertility rates in dairy heifers of over 20%, and spontaneous abortions in cattle as high as 45%.

For example, 450 of 1,000 pregnant heifers fed wheatlage experienced spontaneous abortions. Over the same period, another 1,000 heifers from the same herd that were raised on hay had no abortions. High concentrations of the pathogen were confirmed on the wheatlage, which likely had been under weed management using glyphosate.

Recommendations

In summary, because of the high titer of this new animal pathogen in Round Ready crops,[sic] and its association with plant and animal diseases that are reaching epidemic proportions, we request USDA’s participation in a multi-agency investigation, and an immediate moratorium on the deregulation of RR crops until the causal/predisposing relationship with glyphosate and/or RR plants can be ruled out as a threat to crop and animal production and human health.

It is urgent to examine whether the side-effects of glyphosate use may have facilitated the growth of this pathogen, or allowed it to cause greater harm to weakened plant and animal hosts. It is well-documented that glyphosate promotes soil pathogens and is already implicated with the increase of more than 40 plant diseases; it dismantles plant defenses by chelating vital nutrients; and it reduces the bioavailability of nutrients in feed, which in turn can cause animal disorders. To properly evaluate these factors, we request access to the relevant USDA data.

I have studied plant pathogens for more than 50 years. We are now seeing an unprecedented trend of increasing plant and animal diseases and disorders. This pathogen may be instrumental to understanding and solving this problem. It deserves immediate attention with significant resources to avoid a general collapse of our critical agricultural infrastructure.

Sincerely,
COL (Ret.) Don M. Huber
Emeritus Professor, Purdue University
APS Coordinator, USDA National Plant Disease Recovery System (NPDRS)
