In California, glyphosate phobia results in hazmat suits, respirators to protect against organic chemicals

|

If you’ve followed the often acrimonious debate over GMOs in foods, you’ve probably seen pictures of farmers walking though corn and soy fields bedecked in hazardous material suits and respirators. Why are they wearing them? According to anti-GMO activists, they are protecting themselves from glyphosate, a chemical often paired with GMOs that they claim is a cancer-causing herbicide.

These people wearing hazmat suits are actually Greenpeace activists ripping up genetically engineered plants in the Philippines in 2011—ironic in a tragic way as the plants being uprooted are engineered with the natural soil-dwelling bacterium Bacillus thuringiensis (Bt) to protect crops against pests. Farmers who grow Bt use about 95% less insecticides, according to the USDA. Organic farmers use the same Bt pesticide on their crops in a sprayable form.

Here is another of literally hundreds of similar scare pictures on the Internet. Note the c43bb78db34c1ce5b434d8896ac44fc0accompanying line: “If it’s not safe to breathe…how can it be safe to eat?” It’s a fabricated image and tag; glyphosate has a toxic profile akin to table salt. Farmers use such a diluted form (and such a small amount) of glyphosate on their fields that it does not require the use of protective gear.

Farmers do sometimes use hazmat suits and respirators. Take a look at this picture taken from this video produced in 2011. You can see the farmer decked out in a full protection gear with chemicals spewing from the back of his tractor. Looks pretty ominous, yes?screen-shot-2015-02-14-at-5-26-32-pm

Well, it turns out these are organic cauliflower fields at one of California’s largest family-owned California farms, Lakeside Organic Gardens in Watsonville. They know that spraying their fields with some natural chemicals, like the soapy insecticide being used here, can endanger their health—so they protect themselves.

Travesty unfolding in the organic heart of California

Which brings us to the situation unfolding in towns and cities across America, most recently in Petaluma, California. Petaluma is foodie country. It is in uber-liberal Sonoma County, a hotbed of anti-GMO sentiment. In November, Sonoma will vote on a highly contentious initiative that would ban GM crops and seeds. (A similar ban proposal failed in 2005.)

Although the herbicide glyphosate is still legal for use in the Petaluma region, anti-GMO activists have complained about it in public forums with the hope of getting it banned. Anticipating a ban, public officials have begun introducing alternative weed control methods.

“We’re not under a moratorium, but we’re doing this internally so we can have some data to bring to people to consider,” said Ron DeNicola, parks and landscape manager for the city of Petaluma.

Both the city and the area’s largest school district have stopped using glyphosate, instead trying out various organic solutions. It’s been a disaster so far. The first issue has been price. Glyphosate costs $62 for a 140-gallon mix; the organic products they have tried cost more than a $1000 to cover the same area—a 1700 percent increase. That may be nothing to the residents of one of the richest counties in the United States, but it’s enough to bankrupt the weed management budgets in less affluent places if Petaluma’s “experiment” should become a model.

But the real concerns may be ecological, and to the health and safety of farmers and others who apply the herbicide, according to officials in Petaluma.

“The treatments are also said to be extremely pungent during application, with several workers complaining of eye irritation and one experiencing respiratory problems,” [Joe] DeCarlo[, the district’s director of maintenance,] said. Those attributes have required the use of new protective equipment, something that was not required with Roundup. “It’s frustrating being out there using something labeled as organic, but you have to be out there in a bodysuit and a respirator,” he said.

For those motivated by science and a balanced view of health and environmental risks and benefits, here’s the bottom line: Glyphosate, which is the generic name for Roundup, carries a “caution” label that suggests farmers wear regular clothing that covers their skin. Organic chemical soap concentrates come with a “warning” label: they are often toxic to bees (and other harmless ecologically crucial insects) and “require eyewear, coveralls, and chemical resistant footwear, gloves, headgear and an apron.” Prudent farmers, like those at Lakeside Organic, and the workers in Petaluma, wear respirators.

To cap off the disaster brought on by panic decision-making, the hazardous organic soapy chemicals do not kill the weeds as effectively as glyphosate, Petaluma officials said.

Having used the alternative herbicides over the past two months, DeCarlo said crews have needed to apply the treatments more often to achieve similar results. The plants are also likely to regrow, since the root remains alive underground.

Chemophobia and GMOs

How did anti-GMO campaigners drive Sonoma County, and indeed many other well-meaning cities and regions around the world, into in this bizarre Alice in Wonderland anti-science pickle?

Chemicals scare people. Even worse in many people’s minds are pesticides, which are used in growing crops, and which inevitably end up in our food in miniscule amounts. Scientists assure us that the infinitesimally small amounts of food pesticide residues that we ingest are harmless, but that doesn’t reassure many people who have been caught up in a wave of chemophobia—the irrational fear of all chemicals that dominates mainstream environmentalism. Anti-chemical activism is a huge business, driving the organic and ‘natural products’ movements, and it’s one of the dominant memes in cyberspace. Chemophobia has even trickled into the stories of journalists who are unschooled in risk assessment.

Three years ago, the central mission of anti-biotechnology activists was to convince people that GMOs could cause health problems. Those concerns have largely faded, as one independent global science agency after another—now numbering more than 275—have reviewed thousands of studies and issued public statements affirming that foods grown from genetically modified seeds are as safe or safer than their conventional or organic counterparts. The GMOs-are-safe consensus was underscored in May when the National Academies—the premier independent science organization in the United States—issued a comprehensive review, declaring that no unusual health problems have been linked to GMOs.

As the ability to scare people about the alleged dangers of GMOs has receded, campaigners gradually shifted their focus away from GM foods themselves, instead targeting the synthetic chemicals often paired with them. Their chief bogeyman: glyphosate, which scientists have long established was of milquetoast toxicity, less hazardous than common table salt. [Read GLP’s GMO FAQ backgrounder on glyphosate]

Glyphosate has emerged as the proxy for anti-biotech campaigners to attack GMOs. GMO critics claim glyphosate is linked to autism, cancer, gluten allergies, ‘leaky gut’ syndrome and other disorders. Concerns about glyphosate’s possible health impacts increased in 2015 after the International Agency for Research on Cancer (IARC), a research arm of the World Health Organization, classified glyphosate as “probably carcinogenic,” using what is called a hazard evaluation.

But regulatory oversight agencies in the US, Europe and elsewhere reviewed and rejected IARC’s cancer designation, noting it was based on the questionable quality of the studies evaluated to make its conclusions and that it focused on whether glyphosate might cause cancer in workers exposed to extreme doses over extended periods of times, not whether traces of it in our food pose a danger. The US Environmental Protection Agency’s  Carcinogenicity Peer Review Committee issued a report in October 2015 (stamped ‘final,” it was posted on the web by the EPA in April 2016, then removed for unexplained reasons) questioning IARC’s use of incomplete data, reaffirming its past conclusions that the herbicide is safe as used: “based on the weight-of- evidence, glyphosate is classified as “Not Likely to be Carcinogenic to Humans”. The EPA specifically rejected IARC’s claims that epidemiological studies raise questions of a likely cancer link.

The epidemiological evidence at this time does not support a causal relationship between glyphosate exposure and solid tumors. There is also no evidence to support a causal relationship between glyphosate exposure and the following non-solid tumors: leukemia, multiple myeloma, or Hodgkin lymphoma. The epidemiological evidence at this time is inconclusive for a causal or clear associative relationship between glyphosate and NHL.

In what was widely seen as a rebuke of the findings by the WHO sub-agency IARC, a joint panel from the World Health Organization and the Food and Agriculture Organization of the United Nations issued a review of glyphosate in May 2016, concluding it poses no cancer risks as encountered in food and does not impact our genes.

Simply said, the global science consensus remains that glyphosate is a comparatively mild herbicidal toxicant that does not cause cancer or pose serious health threats.

So what happens now? Petaluma and other communities in the US appear poised to ban glyphosate  and substitute more hazardous, ineffective and costly alternatives. The situation is even worse in Europe, where anti-glyphosate frenzy has frozen the European Commission, which has until June 30th to reauthorize its use or a de facto EU ban will go into effect.

    Yeah, Petaluma, i think you missed the real point. Yes, your workers and, possibly, nearby residents must now suit up while using those organic concoctions but, hey, the purveyors of such can now afford to regularly eat at Alice’s pricey restaurant.

    And, Jon, you thought this is not what Alice Walters [corrected: Waters] had intended?

    • agscienceliterate

      The correct spelling of her name is Waters.
      I used to really like Chez Panisse when I lived in the Bay Area a long time ago. She used to emphasize “local food.” Now it’s anti-GE pro-organic rhetoric. Since Alice Waters has gotten on the woo train, she no longer has my support. Too many other fine restaurants in Berkeley, Oakland, and SF.

    Typo
    a 1,50 percent increase.

  • RobertWager

    A couple years back I was asked by the Mayor to discuss pesticides with the committee looking at banning them. After about 45 mins of me explaining the science I was floored with the response.

    ‘We cannot possibly understand the science so we are going to ban them anyways”

    Sad.

    • Warren Lauzon

      I believe it. If you don’t understand it, it must be bad.

  • Peri

    Thank you for reproducing Monsanto propaganda. You’re doing it for humanity, right?

    • Diana Pena

      How is it propaganda if it’s true?

      • Peri

        There are numerous studies showing that pesticides and other chemicals cause several health problems and most importantly reduce biodiversity in nature.

        Back in the 60ies they used to spray DDT on food and humans, they also claimed that Agent Orange was safe…it was the same companies and mouthpieces that write articles like the one above.

        • Diana Pena

          When tens of thousands of ag workers are studied, glyphosate is found to be safe.

          http://www.ncbi.nlm.nih.gov/pubmed/15626647

          You are absolutely wrong.

          Furthermore, biodiversity is hurt by farming in general because of land demands. Herbicides let us preserve our yields, meaning less land needed to grow food. Biodiversity on your field means weeds choke out your crops. That’s not good.

          Additionally, no one ever said that agent orange was safe. Even Monsanto sent a letter to the Pentagon telling them not to use it.

          Also, agent orange was manufactured by Monsanto Chemical, which bought an ag company in 1996. In 2002, Pfizer bought out Monsanto Chemical. Thus, today’s Monsanto had nothing to do with agent orange. Learn your history before you slander companies.

          Also, DDT didn’t cause health problems. If anything, it improved public health by eliminating malaria from the west.

          Your fear mongering is not appreciated. Also, the fact that you have to resort to the shill gambit proves you have no argument.

        • Jason

          The article wasn’t about pesticides vs no pesticides. It was about knee jerk reactions causing the use of more expensive and more dangerous pesticides, even though they are labelled for organic use.

        • agscienceliterate

          You haven’t posted these “studies.” And your allegations are certainly not supported by many tens of thousands of scientists and hundreds of worldwide science organizations. You know what reduces biodiversity, Peri? Tilling the soil and killing organisms under the surface, an organic practice. And using Bt spray on crops, an organic practice, instead of in the crops themselves, a GE practice, kills non-target insect species. (Bt is harmful to the insect gut, not the human gut.). Please do your homework before you spew this nonsense.

        • Absolute_Shower

          “…pesticides and other chemicals cause several health problems …”
          I can see that you’ve given it a lot of thought.

        • Rickinreallife

          Who said agent orange was safe?. The companies that supplied the product warned that a contaminant in one of the components was unsafe, but the government sprayed it anywa. NO ONE SAID AGENT ORANGE WAS SAFE. YOU ARE DRINKING THE KOOL AID. STOP DISTORTING
          HISTORY.

        • Shadeburst

          Well at least we know you’re not a shill for Big Organic, Peri. Nobody would pay you to write such nonsense.

  • Jennifer Sage

    Typo alert: “Prudent farmers, like those… were respirators.” I think you mean they wear them!

  • PJ

    What’s happening in the US? Everything I read seems to suggest that Americans are getting spooked about everything. Is this extreme behaviour of wearing protective gear in the fields just another expression of this seemingly being spooked?

    • Good4U

      Yes. It’s what happens when The Greatest Generation passes on, and what remains are their spoiled, pampered, narcissistic, self-absorbed spawn. We Americans need a strong dose of reality. Most people here have never set foot outside of a small protective bubble, generally their house, school, grocery store, the local shopping mall. Never been hungry or thirsty for even one day.

      To fix this ignorance situation is not really all that hard. I once took my wife & kids at an impressionable age to Mexico. We walked across the border, then took a 10 minute taxi ride to the center of a border town. We went for a walk, taking in all the sights and smells of this foreign environment just 15 km from the USA. Everything was organic (I mean everything). It took my kids about an hour for them to be begging to come home. For people who might need a somewhat stronger dose of reality, I recommend a year or two in a central or west African “republic”. Any of the southern Asian countries would suffice equally.
