年初，美国颇有成就和颇有名气的植物科学家顿·胡伯博士给美国农业部部长发函，说明了转基因作物的危害风险，其中包括导致不育等危害。胡伯博士不但是学界科学家，而且是美国军方科研专家，还是美国农业部植物疾病恢复部门的科学家，对美国转基因作物的来龙去脉、作用影响和许多秘密是最知情者之一，因而，他的披露转基因作物危害风险的信件在美欧社会引起强烈反响。

消息披露后，一些转基因利益商用学者打出“科学人士”的旗号，先是说那封信件不存在、然后又是骨头里挑刺一般、试图诋毁那封信的内容。在国内，同样，一些“挺转帮”照猫画虎也那么说。于是，有些网友来信询问那封信的真实性等问题。

我做的查询结果：今年三月，美国农业部收到公民依照信息公开法所做的查询，在回复中确认胡伯博士发给美国农业部长的信件属实。那之前之后，路透社等欧美媒体报道说，去年年底，美国环保部门对胡伯博士信件所提出的同类问题展开相关转基因作物的重新调查审核；因工作还处在开始阶段，所以，该部门目前还不能发布任何公告公文。

美国农业部确认胡伯博士信件属实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.

我的补充看法：

[1] 就胡伯博士的信件，孟山都公司做了“我们没发现危害”云云的声明。然而，孟山都公司自己的食堂是搞天然食品而避免转基因食品的，即他们是知道转基因食品的危害风险的。
同样，中国农业官员有机关食堂规章制度，保障他们和他们的家属子女吃的是天然食品和避免转基因食品；可是，他们却编造各种假话谎言、欺上瞒下、要全国民众吃他们不吃的转基因食品。更有甚者，他们动用国家资金搞所谓“公关”，雇用一些舆论枪手，对反对和拒绝转基因食品的人搞恶毒攻击、政治诬告和造谣诽谤，甚至还搞黑客攻击和骚扰等活动，完全没了起码的国家机关的样子。一些负责官员和媒体大谈社会诚信，却对农业官员为利坑民的严重违法乱纪的行为是置之不理甚至放纵，还竭力封杀有关转基因危害风险的阐明。

[2] 美国官方确认属实的胡伯博士信件清楚说明了转基因作物的危害风险。如此，金龙鱼之案就应该有个明确了结：郭成林所言完全属实，应立即无罪释放。--- 且不说转基因如何，有消费者不喜欢某产品和批评某产品，就把消费者当作罪犯一样抓了铐起来、还搞判刑；看看世界地图，有哪个国家的公司和法庭是如此荒唐做事的？！如此推销，可见转基因食品是坏东西，不然，为啥要用暴力强迫民众接受呢？消费者权益和公民权益的安全还有起码保障吗？

[3] 效益风险分析并行（BR分析），是通用所有领域的基本原则。在军方，只说我情而瞒报虚报敌情、是要上军事法庭甚至可能被处死的；在卫生领域，瞒报虚报疫情是犯罪行为、是要严惩不怠的；在财经金融领域，只说如何赚钱而不说投资风险的经理代理，是要被公司解雇开除的。如此，为什么在转基因食品领域，就只说能赚多少钱的经济效益、而不说甚至不许说其对人类健康和生态环境等各方面的严重危害风险呢？中国的民众的生命安全和后代安全、中国的国土农田和生态安全，难道就是那么便宜、那么没价值吗？






附：美国科学家胡伯博士给美国农业部长的信件之原文：



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

APS Coordinator, USDA National Plant Disease Recovery System (NPDRS)
