RBC’s are responsible for delivering oxygen to the body tissues through blood flow. Bacillus thuringensis (Bt) is a bacterium commonly used as a biological pesticide. It is a microorganism that produces toxic chemicals. It occurs naturally in the environment, and is usually isolated from soil, insects and plant surfaces. Prior to this study, Bt was thought to be toxic only to insects, but recent studies are proving otherwise. Dr. Mezzomo and his team of Scientists from the Department of Genetics and Morphology and the Institute of Biological Sciences, at University of Brasilia recently published a study that involved Bacillus thuringensis (Bt toxin) and its effects on mammalian blood. According to the study, the “Cry” toxins that are found in Monsanto’s GMO crops like corn and soy, are much more toxic to mammals than previously thought.
The study was published in the Journal of Hematology and Thromboembolic Diseases(1). We do not support animal testing, and think it is unnecessary. It should really be a no brainer that GMO crops cause significant damage to human health. Studies that don’t require animal testing have already proven the dangers of GMO consumption. This study unfortunately required the use of Swiss Albino Mice if Bt was to be properly examined. At the same time, most of us know that the existence of GMOs is completely unnecessary. Advances in genetic engineering promise the expression of multiple Cry toxins in Bt-plants, known as gene pyramiding.
Therefore, studies on non-target species are requirements of international protocols to verify the adverse effects of these toxins, ensuring human and environmental biosafety. Due to its growing use in agricultural activities, Bt presence hasalready been detected in different environmental compartments such as soil and water. Consequently, the bioavailability of Cry proteins has increased, and for biosafety reasons their adverse effects might be studied, mainly for non-target organisms. Studies are therefore needed to evaluate Bt toxicity to non-target organisms; the persistence of Bt toxin and its stability in aquatic environments; and the risks to humans and animals exposed to potentially toxic levels of Bt through their diet.(1) Thus, we aimed to evaluate, in Swiss albino mice, the hematotoxicity and genotoxicity of four Bt spore-crystals... Scientists tested levels ranging from 27 mg to 270 mg over a seven day period, it was remarkably evident that the Cry toxins were hemotoxic, even at the lowest doses administered. Hemotoxins destroy red blood cells, disrupt blood clotting and cause organ degeneration and tissue damage.
The number of RBC’s, (red blood cells) as well as their size, were significantly reduced, and so were the levels of hemoglobin for oxygen to attach to. Every factor regarding RBC’s indicated some level of damage for all levels of toxin administered and across all cry proteins.
The tests clearly demonstrated that Cry proteins resulting from the Bt toxin were cytotoxic (quality of being toxic to cells) to bone marrow cells. Studies contiually show that these proteins kill blood cells bytargeting the cell membranes of RBC’s. Cry1Ab (the protein produced in common Bt corn and soy) induced microcytic hypochromic anemia in mice, even at the lowest tested dose of 27 mg/Kg, and this toxin has been detected in blood of non-pregnant women, pregnant women and their fetuses in Canada, supposedly exposed through diet .
These data, as well as increased bioavailability of these MCA in the environment, reinforce the need for more research, especially given that little is known about spore crystals’ adverse effects on non-target species (1) Dr. Mezzomo and his team are not the only group of scientists to discover the harmful effects of Bt toxins. Professor Joe Cummins, Professor Emeritus of Genetics at the University of Western Ontario has also studied it (2)(3)(4). He concluded that that there is sufficient evidence that the Bt toxin will impact directly on human health through damaging the ileum, which is the final section of the small intestine that is responsible for the absorption of vitamin B12. He also points out that the Bt cry toxin gene has not been proven to be the same as the natural bacterial gene. As mentioned in the first paragraph, it occurs naturally in the environment, usually isolated from soil, insects and plant surfaces. It seems that everyday brings forth new information regarding GMO’s. We have so much evidence that points to just how harmful these foods are, yet they continue to be mass produced and the corporations that develop them are constantly protected.
The truth still remains, you still have a choice as to what you put into your body. I encourage everybody reading this to further their research, most ‘industries’ we have on the planet today really aren’t necessary, we are just made to believe that they are.
