The biotech industry once told the world that Bt insecticidal crops were only harmful to insects and were harmless to pets and people. But a new study of the ecotoxicological risks of widespread commercial Bt spraying found otherwise. Introban®, a Bt-containing product, caused 100% lethality in amphibians.

Dr. Eva Sirinathsinghii tested the effects of Introban®, a commercial formulation of a Bacillus thuringiensis (Bt) subtype, Bacillus thuringiensis subsp. israelensis (Bti). She discovered that Introban® is toxic to tadpoles of an Argentinian species of frog at environmentally relevant concentrations. The Bti subtype is meant for mosquitoes, in order to prevent the spread of infectious disease.

After being exposed for only 48 hours to sub-lethal concentrations of Introban®, tadpoles of a common South American frog developed serious health problems that led to their death.

Genotoxic effects occurred in days, not weeks or months. Intestinal enzymes that would normally protect the tadpoles from oxidative stress were affected, and the results were 100% lethal. The tadpoles’ immune systems were rendered useless.

Although data have been presented suggesting that Bti products are safe for use, Dr. Lajmanovic at the National Council for Scientific and Technical Research Argentina and her colleagues found that the Bti products used widely in urban and suburban areas have dire effects for the aquatic ecosystem and environment.

The Fuss Over Zika and Mosquito Control

All this is quite interesting to this writer (from an analytical point-of-view of course). The latest “HooRah,” WHO, Pandemic scare seems to be focused on this “insidious” Zika virus (with its purported “association” with Microcephaly) and the now, seeming hysterically driven, mosquito (vector) control programs along with an amazing amount of “emergency funding” ($1.8 B) (also to “encourage” BigPharma to “discover” a new vaccine). But, for the purpose of this examination, let’s just focus on vector control, which reportedly is using particular Larvicide products such as “VectoBac.” VectoBac 12AS Biological Larvicide Aqueous Suspension lists the following ingredients: https://drive.google.com/…/0B0vNY24fkkHTRmpTNWZ…/view… (1)

Okay, having clicked on the link and viewed the data, let’s now examine “Bacillus thuringiensis israelensis (Bti), a group of bacteria used as biological control agents for larvae stages of certain dipterans. Bti produces toxins which are effective in killing various species of mosquitoes, fungus gnats, and blackflies, while having ALMOST no effect on other organisms. Indeed, this is one of the major advantages of B. thuringiensis products in general is that THEY ARE THOUGHT to affect few nontarget species.” (2) (emphasis added)

Now, where have we heard this “bacillus thuringiensis” before? Oh! That’s right:

“When U.S. regulators approved Monsanto’s genetically modified ‘Bt’ corn, they knew it would add a deadly poison into our food supply. That’s what it was designed to do. The corn’s DNA is equipped with a gene from soil bacteria called Bt (Bacillus thuringiensis) that produces the Bt-toxin. It’s a pesticide; it breaks open the stomach of certain insects and kills them.

“But Monsanto and the Environmental Protection Agency (EPA) swore up and down that it was only insects that would be hurt. The Bt-toxin, they claimed, would be completely destroyed in the human digestive system and not have any impact on all of us trusting corn-eating consumers.

Study Shows Monsanto’s Bt Toxin Kills Human Embryo Cells

More evidence has surfaced showing that Monsanto’s Bt toxin, which the company claims doesn’t harm humans, is definitively poisoning the populace. New research out of Canada explains that Bt toxin not only accumulates in human tissue but also kills human embryo cells in pregnant women.

For their study, researchers from the University of Sherbrooke Hospital Centre in Quebec looked at pesticides associated with genetically modified (GM) foods, and particularly Bt toxin engineered into some varieties of GM corn and soy. They focused on how these poisons affect pregnant women and their unborn babies.

Based on an analysis of the blood profiles of 30 pregnant women and 39 non-pregnant women, the team determined that CryAb1, a type of Bt toxin, was present not only in pregnant women but also their fetuses. Additionally, Bt toxin was observed to actually kill human embryos in vivo, or inside the bodies of the women.

This deadly phenomenon is known as reproductive toxicology, and it’s something that Monsanto, when first petitioning the U.S. Food and Drug Administration (FDA) for approval of Bt toxin, promised wasn’t possible. In other words, the company clearly lied to the U.S. government about the deadly effects of this poison, which an earlier study out of the same hospital found is present in virtually all pregnant women’s bodies.

“This is the first study to reveal the presence of circulating PAGMF [pesticides associated to genetically modified foods] in women with and without pregnancy, paving the way for a new field in reproductive toxicology including nutrition and utero-placental toxicities,” wrote the authors.

Bt toxin destroys human kidneys, causes cancer

What this means for the general population is that typical consumption of foods containing GMO derivatives from Bt crops could lead to an inability to have children. Rather than just kill insects as Monsanto claims, Bt toxin directly targets unborn human children as well, according to the study, which means GMO crops themselves are a human pesticide.

“Not only do these cry-toxins (Bt toxin) target the kidney cells of developing human fetuses, but when Cry1Ab and Cry1Ac are combined with Roundup, they can delay apoptosis of human cancer cells,” wrote Christina Sarich from TheRebel.org about the nephrotoxicity and carcinogenicity of Bt toxin.

“What’s worse, glyphosate, the main ingredient in Roundup, also causes necrosis — i.e. the death of human tissue, and this happens even when the substance is found in much smaller amounts than what is currently being used on our agricultural crops. The stuff is still carcinogenic in the parts per trillion range.”

Roundup makes Bt toxin even more harmful

So not only is Bt toxin highly damaging to humans at levels commonly seen in food, but so is Roundup, the “safe” herbicide applied to many GM crops. And when combined, these two poisons become synergistically more toxic than they are separately, a fact that was never even considered during their approval.

Report: Monsanto’s Latest GM Maize Doesn’t Reduce Pests or Increase Yields

Monsanto promised that its latest and greatest GM crop, MON810, a genetically modified (GM) insecticidal maize banned by most of Europe, would increase yields and stop crop loss due to pests. A new report from the government of Aragon in Spain says those promises are empty. [1]

There is an inserted gene in the DNA of MON810 which allows the plant to make a protein that harms insects that try to eat it. The inserted gene is from the bacterium Bacillus thuringiensis, which produces the Bt toxin that is poisonous to insects in the Lepidoptera order, including the European Corn Borer. [2] Three quarters of the corn grown in Aragon, Spain is currently genetically modified, but conventional varieties were tested against GM Maize varieties in 2014.

“Helen,” “Zoom,” and “Kayras” – the non-GM isogenic (parent) lines (plant varieties) – were compared with the GM varieties derived from each line. The genetic insert was the MON810 construct from the US company, Monsanto.

The report found that:

“Per hectare, from 12.6 to 14.3 kg of maize were harvested. The GM varieties and the non-GM conventional comparator had very similar yields – the difference was between 0.2 and 0.3 kilos.”

This means the GM maize did not produce more than conventional strains of maize.
