Roundup’s Toxic Chemical Glyphosate, Found In 100% Of California Wines Tested

News today in California that a judge has ruled the cancer warning label on Roundup does not have to be labeled even though the state will still list the nasty herbicide as cancer causing. Monsanto has known there are serious health effects for decades and has fought to keep the public in the dark.

Roundup’s Toxic Chemical Glyphosate, Found In 100% Of California Wines Tested               

Glyphosate usage has gotten so out of control that it’s seemingly taken on a life of its own and is now showing up even in foods that haven’t been directly sprayed, namely the grapes used to make organic wine.

Glyphosate, the active ingredient in Monsanto’s Roundup herbicide, is the most used agricultural chemical in history. It’s used in a number of different herbicides (700 in all), but Roundup is by far the most widely used.

Since glyphosate was introduced in 1974, 1.8 million tons have been applied to U.S. fields, and two-thirds of that volume has been sprayed in the last 10 years.

A recent analysis showed that farmers sprayed enough glyphosate in 2014 to apply 0.8 pounds of the chemical to every acre of cultivated cropland in the U.S., and nearly 0.5 a pound of glyphosate to all cropland worldwide. [1] 

If you purchase organic foods or beverages, you should theoretically be safe from glyphosate exposure, as this chemical is not allowed in organic farming. But a new analysis revealed glyphosate has now infiltrated not only wine but also organic wine.

10/10 Wines Tested Contained Glyphosate

An anonymous supporter of advocacy group Moms Across America sent 10 wine samples to be tested for glyphosate. All of the samples tested positive for glyphosate — even organic wines, although their levels were significantly lower. [2] 

The highest level detected was 18.74 parts per billion (ppb), which was found in a 2013 Cabernet Sauvignon from a conventional vineyard. This was more than 28 times higher than the other samples tested.

The lowest level, 0.659 ppb, was found in a 2013 Syrah, which was produced by a biodynamic and organic vineyard. An organic wine made from 2012 mixed red wine grapes also tested positive for glyphosate at a level of 0.913 ppb.

How Does Glyphosate End up in Wine?

While glyphosate isn’t sprayed directly onto grapes in vineyards (it would kill the vines), it’s often used to spray the ground on either side of the grape vines. Moms Across America reported: [3]
This results in a 2-to 4- foot strip of Roundup sprayed the soil with grapevines in the middle. According to Dr. Don Huber at a talk given at the Acres USA farm conference in December of 2011, the vine stems are inevitably sprayed in this process and the

Roundup is likely absorbed through the roots and bark of the vines from where it is translocated into the leaves and grapes.”

As for how the organic wines became contaminated, it’s likely that the glyphosate drifted over onto the organic and biodynamic vineyards from conventional vineyards nearby.

It’s also possible that the contamination is the result of glyphosate that’s left in the soil after a conventional farm converted to organic; the chemical may remain in the soil for more than 20 years. [4] 

Glyphosate Detected in 14 German Beers

A study of glyphosate residues by the Munich Environmental Institute also found glyphosate in 14 best-selling German beers. [5] All of the beers tested had glyphosate levels above the 0.1 microgram limit allowed in drinking water.

Levels ranged from a high of 29.74 micrograms per liter found in a beer called Hasseroeder to a low of 0.46 micrograms per liter, which was found in the beer Augustiner. [6] Although no tests have yet been conducted on American beer, it’s likely to be contaminated with glyphosate as well.

Indeed, laboratory testing commissioned by Moms Across America and Sustainable Pulse revealed that glyphosate is now showing up virtually everywhere, including in blood and urine samples, breast milk, drinking water and more. [7] 

The beer finding could be a blow to the German beer industry in particular. The country is the biggest beer producer in Europe and has long prided itself on brewing only the purest beer.

“Das Reinheitsgebot” is Germany’s food purity law. It’s one of the world’s oldest food safety laws and limited the ingredients in beer to only water, barley, and hops (yeast was later approved as well).

Now Monsanto’s chemicals are threatening this German tradition and their reputation for producing the purest beer. As reported by The Local: [8]

“‘In contrast to our colleagues abroad, German brewers don’t use artificial flavors, enzymes or preservatives,’ said Hans-Georg Eils, president of the German Brewers’ Federation, at the Green Week agricultural fair in Berlin.

The keep-it-simple brews indeed suit a trend toward organic and wholesome food, agreed Frank-Juergen Methner, a beer specialist at the National Food Institute of Berlin’s Technical University.

‘In times of healthy nutrition, demand for beer which is brewed according to the Reinheitsgebot is on the rise too,’ he said.”

Glyphosate May Cause Cancer and Other Health Concerns

Many are unaware of the fact that glyphosate is patented as an antibiotic. It’s designed to kill bacteria, which is one of the primary ways it harms both soils and human health. Recent research has even concluded that Roundup (and other pesticides) promotes antibiotic resistance.

Scientist Anthony Samsel, Ph.D. (watch my interview with him above) was the person who dug up the patents showing glyphosate is a biocide and an antibiotic. A study in poultry found the chemical destroys beneficial gut bacteria and promotes the spread of pathogenic bacteria. [9]

Samsel also reported that chronic low-dose oral exposure to glyphosate is a disruption of the balance of gut microbes, leading to an over-representation of pathogens, a chronic inflammatory state in the gut and an impaired gut barrier.

Samsel’s research also revealed that Monsanto knew in 1981 that glyphosate caused adenomas and carcinomas rats.

Monsanto’s own research supports the International Agency for Research on Cancer (IARC) determination that glyphosate is a Class 2A “probable human carcinogen” — a determination Monsanto is now trying to get retracted. Other research has shown glyphosate may:

  • Stimulate the growth of human breast cancer cells [10] 

  • Have endocrine-disrupting effects and affect human reproduction and fetal development [11] 

  • Induce oxidative damage and neurotoxicity in the brain [12]

  • Modify the balance of sex hormones [13] 

  • Cause birth defects [14] 

Glyphosate May Be Even More Toxic Due to Surfactants

Most studies looking into glyphosate toxicity have only studied the “active” ingredient (glyphosate) and its breakdown product, aminomethylphosphonic acid (AMPA). But the presence of so-called inactive compounds in the herbicide may be amplifying glyphosate’s toxic effects.

A 2012 study revealed that inert ingredients such as solvents, preservatives, surfactants and other added substances are anything but “inactive.” They can, and oftentimes do contribute to a product’s toxicity in a synergistic manner — even if they’re non-toxic in isolation.

Certain adjuvants in glyphosate-based herbicides were also found to be “active principles of human cell toxicity,” adding to the hazards inherent with glyphosate.

It’s well worth noting that, according to the researchers, this cell damage and/or cell death can occur at the residual levels found on Roundup-treated crops, as well as lawns and gardens where Roundup is applied for weed control. [15] As written in the International Journal of Environmental Research and Public Health: [16]
“Pesticide formulations contain declared active ingredients and co-formulants presented as inert and confidential compounds. We tested the endocrine disruption of co-formulants in six glyphosate-based herbicides (GBH) … All co-formulants and formulations were comparably cytotoxic [toxic to living cells] well below the agricultural dilution of 1 percent (18 to 2000 times for co-formulants, 8 to 141 times for formulations).

… It was demonstrated for the first time that endocrine disruption by GBH could not only be due to the declared active ingredient but also to co-formulants.

These results could explain numerous in vivo results with GBHs not seen with G [glyphosate] alone; moreover, they challenge the relevance of the acceptable daily intake (ADI) value for GBHs exposures, currently calculated from toxicity tests of the declared active ingredient alone.”

How to Avoid Glyphosate in Your Food

Your best bet for minimizing health risks from herbicide and pesticide exposure is to avoid them in the first place by eating organic as much as possible and investing in a good water filtration system for your home or apartment. If you know you have been exposed to herbicides and pesticides, the lactic acid bacteria formed during the fermentation of kimchi may help your body break them down.

So including fermented foods like kimchi in your diet may also be a wise strategy to help detox the pesticides that do enter your body. One of the benefits of eating organic is that the foods will be free of genetically engineered (GE) ingredients, and this is key to avoiding exposure to toxic glyphosate. Following are some great resources to obtain wholesome organic food.

Eating locally produced organic food will not only support your family’s health, it will also protect the environment from harmful chemical pollutants and the inadvertent spread of genetically engineered seeds and chemical-resistant weeds and pests.

  1. Don’t pay too much attention to the wine study. Glyphosate is already in our rainfall, water, air and bodies. We need to phase it out. Europe is doing this now. We are behind and need to move forward.

    • Mila

      Or you can pay attention and eat and drink only organic — because you would rather reduce the Glyphosate passing through your liver and kidneys.

      • Cappy

        They are finding this chemical in Organic wines as well, It us apparently crossing over through the absorbed nearby watershed. We’re screwed for at least 20 + yrs. Way to go Monsanto!

        • Diana Martin

          True, but every microgram matters. Organic products, including wines, still have much lower levels because they only absorb glyphosate from the water table, not directly sprayed on either side of the plant for weed reduction.

          • Janus Matthes


            It needs to be banned period. If you went over to your neighbors and poured poison all over their yard, you’d be arrested. Close to all the “sustainable” wineries use glyphosate, don’t be fooled.

      • Wendy Nicholls

        The Glyphosate found in 100% of the California wines included “organic” labeled wines as well.

    Le gros porc, ne serait-il pas plutôt monsanto lenfoiré qui a créé le blé OGM arrosé de glyphosate ? Panzani en connaît un rayon question pâtes génétiquement modifiées. Miam miam! merci la multinationale Basf /monsanto. Enfin! deux entreprises fusionnent pour empoisonner le monde de pesticides, de glyphosate, et dogm sous couvert déradiquer la faim dans le monde. Des petits agriculteurs indiens se sont retrouvés dans un 1er temps, à genoux puis en slip, croyant au bienfaiteur monsanto, qui pour finir, se sont suicidés . La preuve? OGM : suicide collectif de 1500 fermiers indiens. source: médiapart. Avec le CETA, bientôt ce sera au tour de nos agriculteurs de nous faire bouffer des OGM dans les fruits et légumes, du poulet à leau de javel, et du veau aux hormones à toutes les sauces et du poisson nourri aux farines animales. Jusquà aujourdhui la France a mis son véto sur les ogm et autres cochonailles provenant de lautre côté de latlantique; malgré que nous les retrouvons indirectement dans nos assiettes via le soja importés des USA. Demain cest le marché européen qui va souvrir à toutes sortes de poisons grâce au CETA. Bon appétit! Les naissances futures seront vertes fluorescentes.

      Pino, we agree that glyphosate is poison and should be banned. The state of California has been fighting the giant Monsanto for years. We have a farmer suing in our courts for health problems this week. There are other formulations that are effective without poisoning our water, soil and air for their profits.

  3. Sharon Marks

    I cannot find a single source that share calendar dates for pesticide spraying in Napa or anywhere for that matter. Do we have a right to know? Thank you!

  4. Molly Smollett

    Monsanto are the same folks that brought us Agent Orange which has affected thousands of
    Vietnam Vets. We must BAN Roundup which has glyphosate as well as other poisons.
    If were able to ban DDT in 1975, we can do it to Roundup! Tell all legislators that is what
    we want!

  5. Jake Arleta

    Simple question, if the wine industry is so pure in this discussion, why are they buying the poison that is killing us? Same answer as Monsanto greed. Monsanto is not shoving it down there throats.

    • Janus Matthes


      They organized their own “third party certifiers” for their “sustainable” program and also allow self monitoring for some of their members. The greenwashing program has been quite successful. Also we need to allow sulfites in organic wines to preserve. France allows this and they are over 30% organic/biodynamic which consumers want.

      • Janus Matthes


        Thanks Tom. Here is “wine” country we live in a toxic soup created by the “sustainable” wine industry. New study (posted) shows every other person in the US will now get cancer in their lifetime. It’s all about corporate profits. If I came over and poured poison on your home, I’d be in court.

    Glyphosate is the ONLY herbicide certified for use in USDA certified Organic food production. Organic farmers use it. It does not persist in the soil for years. Generally speaking it is pulled apart by organic compounds and clay particles which it binds to very tightly. Then bacteria and other microorganisms consume it and break it down further. Most studies I’ve seen say that the glyphosate in the soil is 90% broken down within 2 days. The longest Dissipation ive seen in research is minuscule amounts still detectable al 110 days. The EPA has studied glyphosate for years and has found no evidence that it causes cancer in humans or any other mammals. Quit listening to political activists that call themselves scientists.

    • Janus Matthes


      Warren, You are SOOO WRONG. USDA organic does NOT allow glyphosate to be used. Where are you getting your information? The USGS did a 2 year study in 2010 and found the herbicide still in the soil when the finalized their report. Rodale did serious decades long studies and found at 22 years the poison was still persistent. The degradation depends on soil type. The poison is then passed on into the environment, killing birds and other animals. Soils tested from heavy glyphosate users are devoid of the organisms you say breaks it down. One out of every 2 people in the US now predicted to have cancer, why would you promote disease and death? What are they teaching you in Roswell Georgia? There are over 700 studies done by PEERED REVIEWED, NON INDUSTRY SUPPORTED SCIENTISTS that refute the Monsanto studies (the EPA then passed off as their own). Reagan started allowing chemical companies to submit their own biased studies years ago and it is now the norm. So do you work for Bayer/Monsanto?
      Current USDA NOP (National Organic Program) standards do not allow the use of the herbicide glyphosate on organic crops. However, a new investigation by Tropical Traditions has revealed that the U.S. organic grain market is contaminated with glyphosate.

    • Warren Howard, A few quick Questions ; What is the purpose of Round Up Herbicide ? Does it do its job ? How does it do its job ? Why should we humans be concerned ?
      Answers ; Round Up Weed Killer is used to kill plants. Yes this is the most successful Weed Kill ingredient, GLYPHOSATE that Monsanto has been selling these last 30 years. The way that the GLYPHOSATE in Round Up Herbicide works is it breaks the Shikimate Pathway in plants, which weakens the plant so it will die. The reason humans should be concerned is that this GLYPHOSATE also has the same effect on the Shikimate Pathway of Bacteria, as it will weaken and kill Bacteria. YOU may say so what ! But check out information on our Microbiome, Google it and you will find that we have more Bacteria in our bodies than we have cells.
      So when you eat most all foods or drink most all liquids you are getting a little GLYPHOSATE in your gut that starts to its job, the one it was designed to do, Kill Plants or Kill Bacteria. Sad to say

  7. Robert Forsythe

    Studies on human urine sampled from populations across the United States shows a 100 fold increase. We will see what the result is over the coming years. As usual we are the lab rats for the corporate rich.
