A U.S. Congressman is concerned about safety of glyphosate

“New questions about the safety of Monsanto weed killer Roundup are deeply troubling. I worked on the glyphosate issue last term and I believe consumers should immediately stop using Roundup, whose core ingredient glyphosate has been labeled a likely carcinogen and has been linked to non-Hodgkin’s lymphoma by the International Agency for Research on Cancer. We need to find out if Monsanto or the Environmental Protection Agency misled the public.”

-U.S. Congressman Ted Lieu,  “US Congressman Calls for DOJ Investigation into EPA-Monsanto Glyphosate Collusion” Mar 17 2017 – by Sustainable Pulse,

http://sustainablepulse.com/2017/03/17/us-congressman-calls-for-doj-investigation-into-epa-monsanto-glyphosate-collusion/#.WMv1yjvytPb

An employee of the EPA may have colluded with Monsanto to suppress investigation of the safety of glyphosate and the herbicide Roundup.

As many as 80% of dogs with Parvo virus die from it, but mine survived

When my dog was a puppy she was very sick from Parvo virus. It causes severe vomiting and dehydration can be deadly. Intravenous fluids were given by a vet and she slowly recovered but had no appetite. Home cooked meats were accepted though but then she would relapse as I tried to ease her back onto regular dog food.

After months she was more stable and able to ease back onto the commercial dog food but prior to that it seemed that any fortified foods would make her sick again. Phosphorus and calcium from milk-bone type dog biscuits also made her sick. I had already been reading about the nutrient’s role in human infectious disease and so I stuck with the months of chopping home cooked meats for her.

I wrote about the story and included photos in this post:

I hoped that sharing the story would help other canines to survive parvo virus — just withhold extra vitamin D and excess phophorus and calcium while fighting the sickness. The virus must be/ may be one of the type of pathogens that have learned how to modify the vitamin D receptor metabolism. It is involved closely with the immune system and protecting against infection.

From a different old post: “Canada is farther north than most of the United States and yet their population’s average vitamin D level is normal (50 nmol/L). [5, 6] The number of Americans with vitamin D levels below 30 nmol/L increased between a study performed from 1988-1994 (45% > 30nmol/L, n=18,883) and one performed in 2004 (23% > 30nmol/L, n= 13,369) but there is some controversy over whether differences in how the lab test was processed might have skewed the results. [8]”

— I had been concerned in the past that this odd difference in population averages might be due to increased infection with pathogens that affect vitamin D in the US population compared to the Canadian population but after learning about the inhibition of CYP enzymes by glyphosate that makes more sense as an explanation for a populationwide difference. Some people have infections that affect vitamin D metabolism (see next paragraph for more info), but many many many more people eat food every day, and glyphosate is used on crops that are used as ingredients in most prepared foods.

From a different old post: Tuberculosis, I learned recently, is also a type of infection that interferes with normal vitamin/hormone D metabolic pathways. The vitamin D receptor (VDR) plays a role in the ability of white blood cells to kill infected cells and cancerous cells. Some pathogens have developed ways to suppress the Vitamin D Receptor’s activity so white blood cells aren’t able to effectively resist the infection process. Other pathogens that have been shown to reduce the activity of the Vitamin D Receptor, in addition to the pathogen that causes Tuberculosis, include the mold Aspergillus, the viruses that cause Epstein-Barr chronic fatigue syndrome and HIV/AIDS, and the autoimmune diseases sarcoidosis, Crohn’s Disease, and Rheumatoid Arthritis. Elevated levels of 1, 25(OH)2D are seen with the bacterial infections: “Elevated 1,25(OH)2D appears to be evidence of a disabled immune system’s attempt to activate the VDR to combat infection.” [page 19, 1]

I’m glad my puppy survived Parvo virus. It would be nice if more could survive deadly diseases, especially when it is as easy as not fortifying food – not adding something. All we would need is some dog food that isn’t fortified – but you can’t buy it because it doesn’t meet the dog food regulations.

Benicar and curcumin, an extract of turmeric, are both analogues – similar shaped – to hormone D. They can activate the vitamin D receptor and might help patients fight some of the diseases that affect the vitamin D receptor – depending on the type of infection. Receptors and hormones or their analogues act like puzzle pieces or a lock and key that fit together. The analogues might be similar to a master key/skeleton key that can fit in the lock and bump out any ligand/blocking chemical that the infection produced to inhibit the body’s immune system. The vitamin D receptor when activated can then activate aspects of the immune system.

Nutrient content found to be different in GMO soy; a link

Glyphosate tolerant GM soybeans were found to contain high residues of glyphosate and AMPA, a breakdown product of glyphosate. Nutrient content was also found to be different between the glyphosate tolerant GM soybeans and organically grown soybeans. The GM soybeans had less sugars, protein and zinc than the organically grown soybeans and had more omega-6, a less beneficial type of fatty acid.

Compositional differences in soybeans on the market: Glyphosate accumulates in Roundup Ready GM soybeans.

    Glycine, Cheerful Juice, and testing for glyphosate

    My experiences with taking a larger dose of the free amino acids glycine and methionine proved to my satisfaction that they are indeed essential for physical and mental health. In definition methionine is considered essential, we can not synthesize it and need an external source while glycine is considered nonessential, we can make it from other chemicals. For someone who can’t properly breakdown either though they might both be considered essential for health. It has been helping my mood and health.

    I’ve continued to take the amino acids in a half teaspoon dose since the evening I took the full teaspoon dose late at night and couldn’t get to sleep. Essential nutrients can often have ranges for how much is helpful; too little or too much of many things can cause different types of symptoms. The taste isn’t better but I’ve (almost) acquired the taste for it — the astringent tang of a Pinot Noir was the closest taste I could think of —  which does turn out to contain free amino acids, including methionine and glycine. [http://skipthepie.org/beverages/alcoholic-beverage-wine-table-red-merlot/compared-to/alcoholic-beverage-wine-table-red-pinot-noir/#proteins]

    Probably a few people can relate to the idea of red wine being a “Cheerful Juice,” it turns out that the free amino acids may have something to do with it.

    What I did find is that having a genetic defect in the metabolic pathway of an essential amino acid such as glycine can have significant negative effects on mood and energy level and that simply adding an external source of the missing nutrient can have significant positive effects.

    The genetic defect that I have may be rare, I don’t know, but if glyphosate is able to substitute for glycine within physiology then an external source of purified glycine may also be beneficial for anyone eating foods based on ingredients that may contain traces of glyphosate.

    Testing for the presence of glyphosate would not be as simple as testing for the free amino acid however; if it had been incorporated into proteins in place of glycine, then the glyphosate would only be discovered by the lab test if the longer protein chains were broken down first into the free amino acids — and glyphosate if it had been incorporated into the protein instead of glycine.

    Another way to test to see if glyphosate is being incorporated into the structure of proteins in place of glycine would be to add radioactively tagged glyphosate into a system capable of assembling proteins and then test the new mixture to see whether the radioactively tagged glyphosate was used in place of glycine within the newly synthesized protein chains.

    Glyphosate was found within vaccinations that were independently tested by a non-profit group, Moms Across America, but the company Monsanto has since stated that the lab screening that was used was invalid and the testing system Monsanto used found no residue of glyphosate in vaccinations. [http://monsantoblog.com/2016/09/13/monsanto-responds-to-flawed-study-by-samsel-claiming-glyphosate-in-vaccines/] — A test for free amino acids wouldn’t find glyphosate that had been incorporated into proteins of agar gelatin or viral proteins.

    The herbicide Round-Up found more dangerous than glyphosate alone

    The herbicide Round-Up contains glyphosate which is considered the active ingredient but research suggests that the supposedly inert ingredients in the mixed product make Round-Up as much as 125 times more dangerous to health than glyphosate alone. An international society for science has assembled a review of literature on the topic within the following article:

    Round-Up ready crops have been found to require more water and do less well in drought situations than normal crops. Pigs fed GMO based foods were found to become significantly healthier when the farmer switched to non GMO based feed for them.

    Glyphosate residues have been found to drop after individuals switched to a diet based on non GMO, organic foods and autism symptoms were found to improve for individuals who were switched to a non GMO organic food diet. Single case studies may be considered anecdotal and not worth considered but each and every patient is a single case study for themselves.

    How many people need to get sick in the U.S. before we decide that we would rather not be experimented on by agribusiness and the processed food industry?

    Excerpts from the article:

    Glyphosate widespread in the environment and in our bodies

    “Due to the official ‘safe’ status of glyphosate, data on how much we are being exposed have been scarce, forcing citizen activists and civil society organizations to find out for themselves. Friends of the Earth Europe commissioned an analysis of 182 volunteers across 18 EU countries and found detectable levels in 44 % of urine samples [13] with concentrations ranging from 0.16 ug/L average in Switzerland, to 1.82ug/L in Latvia. Of the UK citizens tested, 7 out of 10 were positive. In the US, urine samples show concentrations 8 times those in Europe [13]. The analysis, commissioned by Moms Across America, also tested 10 mother’s breast milk, which came up positive for glyphosate with levels ranging from 76 µg/L to 166 µg/L (76-166 ppb) (see [14]). These levels are 760 to 1600 times higher than the European Drinking Water Directive allows for individual pesticides, and raise obvious concerns as they fall within the range of concentrations at which developmental toxicity has been observed in animal studies (see below). This analysis is the only study on breast milk to date, as no government or public health body has found it necessary to carry out any study on bioaccumulation in internal organs and tissues or in breast milk fed to infants.”

    Health of American citizens deteriorating

    “One argument for the safety of GM food and their associated pesticides is that the US has been consuming them for years without ill effect. However, in the absence of labelling GM foods, it is illegitimate to make such a claim. On the contrary, there has been a drastic deterioration of public health in the US since GM crops were introduced. A new publication by Swanson and colleagues plots the rise of 20 chronic diseases using available US government data, all correlating closely with increasing glyphosate application to corn and soy crops, especially over the past several years. The diseases included cancers, Parkinson’s, autism, obesity, diabetes, heart disease, digestive disease and kidney failure [62]. Correlation does not prove causation, but such strong association certainly cannot be dismissed, especially in combination with the plethora of other evidence from laboratory studies, and the experiences of doctors in their clinics and farmers in the fields. For a detailed analysis of the study please see [67] Marked Deterioration of Public Health Parallels Increase in GM Crops and Glyphosate Use, US Government Data Show ( SiS 65).”

    Glyphosate, a consensus statement; a link

    The following link is to a long but very thorough paper regarding the herbicide glyphosate and what has been discovered about its potential risks to health:

    In my last post I described glyphosate and glycine as being similarly shaped puzzle pieces on one side but not the same on the other side. Another way to visualize the possible way glyphosate may be substituting for glycine would be to consider a lock and key. If the lock is being built with glyphosate instead of with glycine then the shape of the keyhole changes and the normal ‘keys’ will no longer fit in the lock in order to activate the desired function of the protein (a protein that normally contains glycine would be the lock in this example, an enzyme or other type of messenger chemical that activates it might be the key).

    Updates regarding glycine, health, and glyphosate

    9/20/2016 Updates to a couple previous posts [1, 2]: See the following post on my other website, lpaad.org  for more about use of dimethylglycine as a supplement and the gene defect that can affect its metabolism:

    A recent post included details from Professor Seneff’s talk on dietary and lifestyle tips for reducing exposure to glyphosate and which nutrients might be affected by the chemical and food sources. Increasing intake of a substance that is being inhibited can sometimes help overcome the inhibitory effect. Roughly, the theory being suggested is that glyphosate acts as a puzzle piece that can fit in one side of the puzzle but won’t fit with the other pieces, as it is partially filling the remaining open spot on the piece. Glyphosate also does not provide methyl groups as glycine would. Methyl groups help protect against cancer among other important functions such as re-methylating molecules of vitamin B12 and  folate.

    The presence of glyphosate in vaccines almost confirms that theory being presented by Professor Seneff. If it was being built right into the animal collagen  that was used in the Petri dishes for culturing the vaccine microbes, then they would be building their own growing microbe bodies out of glyphosate too.

    A building block is a building block, a puzzle piece is a puzzle piece —  whether they fit well together or not, is an important question to ask before strewing them all over the landscape and food supply, and injecting them straight into tiny infants and pregnant women.

    Glyphosate was found in vaccines; and tips for reducing dietary exposure

    The nonprofit organization Moms Across America paid to have five types of vaccines tested in an accredited laboratory for the presence of the herbicide glyphosate. The chemical, which was originally patented as an antibiotic and mineral chelator, has never been tested or marketed as an injectable drug. Vaccines are injected directly into the blood stream which bypasses the protection of the gastrointestinal system.

    The World Health Organization has advised that glyphosate is a probable carcinogen and it may affect hormones which would make it dangerous potentially for pregnant women and their expected infants:

    “Honeycutt continues, “The public must know that their vaccines likely contain glyphosate, a toxic weed killer, which is acknowledged by the EPA as a “reproductive effector” ( i.e.: endocrine disruptor) which “can cause liver and kidney damage” and has been shown to be a neurotoxin. The WHO has deemed glyphosate a probable carcinogen.” – Moms Across America

    The MMR II vaccine by the Merck company was found to have the highest level of glyphosate, 25 times more than what was found in the other four types of vaccines that were tested: “had levels up to 25 times higher than the other vaccines, at 2.671ppb.” The MMR II vaccine has been associated with autism as an adverse reaction (possibly due to an encephalitis reaction which then leads to the more extreme brain damage seen in patients with autism).

    This supports the theory discussed by Professor Seneff, that glyphosate may be in vaccinations due to the use of animal products in the gelatin based Petri dishes in which the antigens for the vaccinations are grown. The theory suggests that glyphosate is similar enough to the amino acid glycine that it may be being built right into the protein structure of the animals body parts which include the collagen that is used to make gelatin. The glyphosate would be acting like a puzzle piece that kind of fits in one side of the protein but has the wrong shape on the other side of the puzzle piece so no other pieces of the puzzle can be added afterwards. One part of glyphosate would fit well into the protein structure but then another part wouldn’t be able to do what glycine does – which is donate methyl groups – which can help protect against cancer.

    Some genetic canaries in the coal mine, such as myself, may have errors in the methylation cycle that disrupt the glycine function without needing any help from glyphosate. While filling my vitamin boxes for a week’s supply I was reminded that one of the supplements I added after getting my genetic methylation cycle results is . . . DMG . . . which is Dimethylglycine. I’ve been taking one of the capsules in the morning and one in the evening — but there is no guidance for how much of it I might need with my particular genetic defect.  My favorite phrase – or least favorite: “More research is needed.” Current information available suggests 2 grams of glycine per day may be a typical amount provided by the diet but ten times that amount may increase health benefits, no toxicity upper limit has been set; https://draxe.com/glycine/

    Professor Seneff included tips for how to possibly reduce your exposure to glyphosate and some strategies that have been used on farm animals who were made sick by acute exposure to glyphosate.

    Professor Seneff’s slides for her discussion lists”Some Important Nutrients“:

    • Curcumin
    • Garlic
    • Vitamin C
    • Probiotics
    • Methyl tetrahydrofolate – (this is the bioactive form of folic acid)
    • Cobalamin
    • Glutathione
    • Taurine
    • Epsom salt baths  [My how to tips for Epsom salt baths]

    She also recommends:

    • Get Grounded” — ie work on general lifestyle and stress reduction strategies;
    • Eat organically grown foods whenever possible;
    • Eat foods containing the mineral manganese; (as glyphosate is a mineral chelator which may limit manganese’s availability for essential functions.) She mentions a few foods and shares an image which appears to include: organic whole grains, seeds, organic tofu and other beans, shellfish, tea, dark green leafy vegetables. This list provides more information — for example cardamom and pumpkin pie spice are sources of manganese:  http://nutritiondata.self.com/foods-000126000000000000000.html
    • Eat foods containing sulfur; (and/or take the Epsom salt baths which would supply magnesium and sulfur.) She mentions a few foods and shares an image which appears to include: beer, cabbage, organic eggs, especially the yolk, crab, shrimp and scallops, cheese, onions, garlic, organic liver, chicken, and something I’m not going to try to guess. Based on this list of the sulfur content of many foods the image may include a picture of dried apricots:  http://apjcn.nhri.org.tw/server/info/books-phds/books/foodfacts/html/data/data5g.html

    Professor Seneff speaks very quickly, I may have missed some of her tips for trying to protect yourself from exposure to glyphosate.

    She includes information about extracts from common plants that can treat glyphosate poisoning including:

    Extracts from common plants such as dandelion, barberry, and burdock can protect from damage, especially if administered prior to exposure.”* (*C Gasnier et al. Journal of Occupational Medicine and Toxicology 2011, 6:3). [https://occup-med.biomedcentral.com/articles/10.1186/1745-6673-6-3]

    And cows with glyphosate poisoning have been treated with:

    Activated charcoal, bentonite clay, humic and fulvic acids, and sauerkraut juice have been shown to be effective in reducing glyphosate and improving animal health.“** (** H Gerlach et al., J Environ Anal Toxicol 2014, 5:2). [http://www.omicsonline.org/open-access/oral-application-of-charcoal-and-humic-acids-influence-selected-gastrointestinal-microbiota-2161-0525.1000256.pdf]

    See the research papers for more detail and a functional medicine professional may be able to help guide individualized treatments with some of the items that are mentioned such as activated charcoal– but seek guidance, professional help is recommended even when using natural treatments.

    The herbicide glyphosate is similar to glycine, an amino acid

    The herbicide glyphosate was originally patented as an antibiotic and as a mineral chelator (a protein that can bind and transport minerals). It has been in use as an agricultural herbicide since 1975. However it’s use greatly increased in the last ten years since genetically modified Round-Up Ready crops were developed. A professor from Massachusetts Institute of Technology has been researching glyphosate and it’s possible role in the development of autism.

    Professor Seneff gave two presentations at an Autism One conference earlier this year. The PowerPoint slides to the lectures are available in links included in the Tweets below, click these links for the pdfs to each video: people.csail.mit.edu/seneff/2016…

    The first video includes more information about the chemical similarity between glyphosate and glycine. Glycine is an amino acid that provides methyl groups. Glyphosate is very similarly shaped but has an extra side chain and it wouldn’t provide methyl groups. It is possibly similarly shaped enough, however, for glyphosate to be incorporated into the structure of proteins instead of glycine. It would be like a puzzle piece that fits into another piece but won’t allow any other pieces to be added. Glyphosate may fit in glycine’s spot within a protein but then wouldn’t provide any methyl groups and the extra side chain could interfere with receptor function – like having an extension cord with prongs that no longer can fit into an electric socket because the socket is already blocked with something else.

    The risk to health if this is true could be significant. Many proteins contain glycine and any one of them might be important in a variety of ways which glyphosate could disrupt. This is in very early stages of research but the impact could also affect vaccinations because the collagen used to culture material for vaccinations could contain glyphosate instead of glycine if the animals from which the collagen was obtained had been raised with feed containing glyphosate residue.

    Zika virus that grew in an environment that contained glyphosate might have it incorporated into proteins instead of glycine which could be making the disease far more dangerous prenatally than it had been in past decades before glyphosate became widely used. Zika infections had not been associated with microcephaly until recently. The second video goes into more detail about how glyphosate could be making Zika more dangerous.

    Professor Seneff explains in more detail about the glycine/glyphosate similarity in the first video:

    I will get back to this topic after rewatching the videos and taking notes on the recommendations she makes about food and lifestyle strategies for reducing glyphosate exposure or reducing glyphosate levels that may be stored within the body.

    9/20/2016 Update: See the following posts for more about glycine and glyphosate:

    Glyphosate was created as an antibiotic and mineral chelator but is being used as an herbicide

    Every cell in our bodies depends on mitochondria to produce energy from stored sugar. Mitochondria are actually bacterial in origin. They are smaller than human cells and have their own DNA that is different from the the human cell DNA. Glyphosate is presumably safe for use in the human food supply because it only affects a metabolic pathway found in plants and bacteria however if every cell of our human bodies also depends on mitochondria which are bacterial in origin then is the antibiotic glyphosate truly safe for human use? Or for use in food for farm animals – which also depend on mitochondria to produce energy from sugar (glucose is the form of sugar that is broken down for energy within mitochondria).

    A concerned scientist has been studying the topic for years and has been writing about the topic, read more: http://www.westonaprice.org/health-topics/roundup-the-nontoxic-chemical-that-may-be-destroying-our-health/   The topic is dangerous to write about however within the current business world which seems to be oriented to support corporate profit  over the long term viability of our ecosystem. The authors of that paper have been labeled ‘debunked’ or something similarly dismissive.

    Glyphosate is being sprayed on invasive plants in wild areas and within waterways that are overgrown with invasive plants. However the affects of the antibiotic and mineral chelator on the desirable plants and wildlife is not known. A mineral chelator generally has been thought of as helpful, the phrase refers to chemicals that can bind onto a mineral and help transport it into cells or into the body from the gut. A mineral chelator that binds onto toxic minerals and helps transport them into the body might be not helpful or a mineral chelator that binds onto nutrients in the soil and prevents them from being absorbed by the plant would also be not helpful to the plant or possible to the humans or animals eating the plant.

    Glyphosate was first patented as an antibiotic and as a mineral chelator before it was developed into an herbicide.

    Glyphosate has been found in all samples of California wine that was tested in one study and it was found in over 40% of organically grown honey that was tested in another study and in over 60% of the commercially produced samples of honey. The chemical can be difficult and expensive to screen for using many of the typical methods however another method was used for screening the samples of honey:

    The a1nalytical program included the extraction of glyphosate from the various matrices and the subsequent determination of glyphosate residues by enzyme linked immune sorbent assay (ELISA).” “(Figure 4) depicts the concentration of glyphosate in honey samples grouped by growing method of source pollen: organic (11 samples) and traditional (58 samples); 5 of the 11 organic samples had glyphosate concentrations above the method LOQ with a range of 26 to 93 ng/g and a mean of 50 ng /g. Of the fifty-eight non-organic honey samples, thirty-six samples, or sixty-two percent (62%), contained glyphosate concentrations above the method LOQ, with a range of 17 to 163 ppb and a mean of 66 ppb.

    Figure 5 includes data comparing samples of honey produced in countries that don’t allow GMO Round-Up Ready crops with samples from countries that do. Samples from countries that don’t allow GMO crops had an average of 31 ng /g of glyphosate compared to 71 ng/g of glyphosate found in the samples of honey produced in countries that do allow GMO crops.  “Although glyphosate is not acutely toxic to bees, it is chronically toxic to animals and is reported to disrupt the endocrine system [35,36] and a recent study indicates that honey bees exposed to increasing sub-lethal concentrations of glyphosate exhibit a decrease in acetyl cholinesterase (AChE) activity [37].” Further study is recommended in order to further assess whether glyphosate might be adding to the loss of bee hives that has been associated with use of neonicotinoid chemicals. Read more: http://www.omicsonline.org/open-access/survey-of-glyphosate-residues-in-honey-corn-and-soy-products-2161-0525.1000249.php?aid=36354

    Fewer samples of wine produced in California were tested but 100% of the samples (n=10) were found to have glyphosate contaminants. The wine produced from grapes grown organically  did have less of the contaminant than the commercially produced wine. That may not help the people living in the areas where grapes are grown for the California wine: “According to the CA Dept of Health, breast cancer rates in the Sonoma, Napa and Mendocino counties is 10 to 20 percent higher than the national average.” “German scientists have shown that 0.1 ppb of glyphosate, which is patented as an antibiotic, has been shown to destroy the beneficial gut bacteria and promote the proliferation of pathogenic gut bacteria.(2)” “0.1ppt of glyphosate has also been shown to stimulate the growth of breast cancer cells.(3)” “Glyphosate has also been shown to increase antibiotic resistance, which could be leading to superbugs (9)” Read more:  https://d3n8a8pro7vhmx.cloudfront.net/yesmaam/pages/680/attachments/original/1458830087/GlyphosateContaminationinWinePressReport_(2).pdf?1458830087

    So how much glyphosate might be too much? — Not much if 0.1 ppb is enough to destroy our beneficial gut bacteria and 0.1 ppt is enough to stimulate growth of breast cancer cells. And if it’s presence in the environment is increasing the risk of more pathogens developing antibiotic resistance than any of it might already have been too much for people with antibiotic resistant pneumonia.

    And how much glyphosate might be deadly? — Twenty milliliters was not quite enough for at least one suicidal patient who did manage to make herself sick with a antibiotic resistant bacterial infection after ingesting the 20 ml of glyphosate in a suicide attempt (this is sad but is not uncommon – many people commit suicide by eating agricultural chemicals). (Twenty milliliters would be equal to about 4 teaspoons of glyphosate.) http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4289481/

    How many ppb in one milliliter? –> search engine –>

    “This is the same as grams per 1,000 liters, which may be converted to milligrams per liter (mg/L). Therefore, 1 g/ m3 = 1 mg/L = 1 ppm. Likewise, one milligram per cubic meter (mg/m3) is the same concentration in water as one microgram per liter (ug/L), which is about 1 ppb.”

    So not much glyphosate is needed to cause negative health effects in humans and in the environment. It can break down quickly but may also take up to twenty years to completely break down. If excessive amounts of glyphosate are allowed to accumulate it may become difficult for normal seeds to be able to grow and genetic modification might be necessary for producing any viable crops in areas where glyphosate residue becomes prevalent (such as in any countries that allow GMO crops and use of glyphosate as a desiccant.)

    How much might be too much in nature? One part per million (1 ppm) equivalent to what might be found in the environment of countries that use glyphosate was found to be enough of a dose to produce deformities in 60% of the tadpoles of a tree frog. “Jayawardena et al. (2010) found nearly 60% malformations in tadpoles of the tree frog Polypedates cruciger treated with an environmentally relevant concentration of 1 ppm Roundup.” The formulated product (glyphosate plus surfactants or other additives) was found to be more harmful to offspring than the glyphosate alone. How much is too much in our food supply? We don’t know for sure but we are beginning to know more about how much may be present in our food supply: “Residues of up to 17 mg/kg of glyphosate have been found in harvested soybean crops [10].

    Back to the search engine –> “1 mg/kg = 1000 ppb” So –> “Residues of up to [17000 ppb or 17,000,000 ppm] of glyphosate have been found in harvested soybean crops.” Which seems like it would be enough to cause malformations in at least 60% of tree frog tadpoles if they were exposed to Round-Up Ready soy.

    Maybe it is completely safe for everyone — except the 2% who are developing autism and the 5.3 million people living with Alzheimer’s Disease.  North Dakota has the highest rate of mortality due to Alzheimer’s Disease and Nevada has the lowest rate.  http://www.alzheimers.net/resources/alzheimers-statistics/

    Most glyphosate used at harvest time is done on spring and durum wheat, and mostly in the northern tier States (North Dakota & Montana) and ...”  This article is debunking a different article about use of glyphosate as a desiccant – this article states that is actually a rare practice – except possibly in North Dakota and Montana.

    The search engine suggests that glyphosate has been used for invasive plant control in Nevada but did not turn up agricultural references. A study on use of glyphosate for helping establish native plants in an area with invasive plants. The glyphosate use on the invasives did help with getting the native plantings established instead. http://sfc.smallfarmcentral.com/dynamic_content/uploadfiles/152/Nevada.pdf

    The search term results: https://www.google.com/search?q=use+of+glyphosate+in+Nevada&rlz=1C1CHWA_enUS600US600&oq=use+of+glyphosate+in+Nevada&aqs=chrome..69i57.4494j0j7&sourceid=chrome&ie=UTF-8

    The search turned up a paper that has since been retracted after it was published due to some delay in the peer review process but the paper can still be viewed. It suggests there is a correlation between glyphosate use which causes an increased need for nitrogen based fertilizers because the glyphosate can affect soil bacteria that normally would make nitrogen more available so more nitrogen based fertilizer is required and which can lead to more nitrogen dioxide being released into the air which can affect ADHD risk and is also a gas involved in global warming. the paper turned up in my search terms because Nevada didn’t have some data that other states had made available. States with data available regarding glyphosate use between 2006-2009 suggest that Arizona and Utah used less than in previous years,

    It took fifty years or so before corporate control of science regarding cancer risk and smoking was freely available to consumers and it has taken twenty or so years to reveal Exxon’s role in denying the impact of fossil fuel use on climate change. It may take a while to reveal that spraying an antibiotic and mineral chelator is bad for soil health and health of other life forms. In the mean time I will continue to try to avoid sources of Round-up. It may be the combination of the adjuvants/surfactants that are used with the glyphosate that makes it more of a risk for neurodegenerative harm such as autism or ADHD than studies with glyphosate alone have suggested or it may be the changes in nitrogen based fertilizer use as suggested by the (retracted) article on ADHD and Round-Up.
