Emergency! Pathogen New to Science Found in Roundup Ready GM Crops?
USDA senior scientist sends “emergency” warning to US Secretary of Agriculture Tom Vilsack on a new plant pathogen in Roundup Ready GM soybean and corn that may be responsible for high rates of infertility and spontaneous abortions in livestock Dr. Mae-Wan Ho

An open letter appeared on the Farm and Ranch Freedom Alliance founded and run by Judith McGeary to save family farms in the US [1, 2]. The letter, written by Don Huber, professor emeritus at Purdue University, to Secretary of Agriculture Tom Vilsack, warns of a pathogen “new to science” discovered by “a team of senior plant and animal scientists”. Huber says it should be treated as an “emergency’’, as it could result in “a collapse of US soy and corn export markets and significant disruption of domestic food and feed supplies.”
The letter appeared to have been written before Vilsack announced his decision to authorize unrestricted commercial planting of GM alfalfa on 1 February, in the hope of convincing the Secretary of Agriculture to impose a moratorium instead on deregulation of Roundup Ready (RR) crops.
The new pathogen appears associated with serious pervasive diseases in plants - sudden death syndrome in soybean and Goss' wilt in corn – but its suspected effects on livestock is alarming. Huber refers to “recent reports of infertility rates in dairy heifers of over 20%, and spontaneous abortions in cattle as high as 45%.”
This could be the worst nightmare of genetic engineering that some scientists including me have been warning for years  (see Genetic Engineering Dream or Nightmare, ISIS publication): the unintended creation of new pathogens through assisted horizontal gene transfer and recombination.
Huber writes in closing: “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.”
The complete letter is reproduced below.
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:
Pathogen Location and Concentration
Linked with Outbreaks of Plant Disease
Implicated in Animal Reproductive Failure
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 wheatlege 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 wheatlege, which likely had been under weed management using glyphosate.
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.
