Online Student Donna Turner Woods Interviews Darryl Benjamin on “Nanotechnology in Agriculture and Food” for her final paper in Professor Renee Ciulla’s Global Food Systems class.

DTW: Since we know what Nanotechnology is and how it was originally being used for replication of matter, should there be concern if it used in agriculture – crops and livestock, and human and animal consumption that replication of cells will take place?  Meaning once ingested, the replication process might latch onto the human and animal cells.  What would the consequences be?

DB: Nanotechnology is a giant leap forward in the manufacturing, energy, electronics, and computing fields, but I’m not so sure I want it in my food. Engineering food is a tricky business because there are always unintended consequences. Scientists tend to focus on a narrow spectrum of study that verifies preconceived outcomes. But it took millions of years to evolve the human body, so I question the safety of nanofoods, which has only been around for half a dozen years.

The tiny size of nanomaterials permits them to pass more easily through cell membranes and other biological barriers, allowing these particles to be easily taken up into organisms and cause cellular dysfunction. Potential risks to humans include DNA damage leading to cancer, brain, and heart illnesses. Scientists need to look at the whole picture and conduct decades of testing before the biological interdependencies and complexities of living systems can be sufficiently evaluated as safe enough to put nanoparticles in our food.

DTW: We know about GMOs/GEOs which are gene and DNA altering seed and its effects on crops – the plants themselves, crop yields, and the environment – soil and water absorption (Leopold Study 2013) but what we do not know is the long-term effects they have on human and animal consumption. Is there any data on Nano consumption? If there is are there safety parameters in place for human and animal consumption of Nanos?  Meaning, the amount one can consume before it becomes harmful?  If so, how is it measured?

DB: You bring up an important point. Just as GMOs quietly entered the food supply, so too did nanoparticles in food. Unfortunately, no nanotechnology-specific regulation or safety testing is required before manufactured nanomaterials can be used in food, food packaging, or agricultural products. Unlike GMOs where there are conflicting studies, there are almost no data on nanoparticles in food. We know nanoparticles can be more chemically reactive and more bioactive than larger particles of the same chemicals, and that greater bioactivity may introduce new toxicity risks, but where are the studies?

We should be concerned not just about consumption, but workers who may encounter nanomaterials during production, packaging, transport, distribution, and waste disposal of food and agrochemicals. Studies have shown that nanomaterials can enter the bloodstream via the lungs simply by inhaling — raising major occupational health and safety concerns.

The lack of standards and internationally recognized measurement methods, coupled with the shrouding of the nanotechnology industry and bolstered by lack of regulation has created significant challenges to simply understanding where nanomaterials are being used and the reality of their interactions with the public and our environment.

Transparency would require all relevant data related to safety assessments, and the methodologies used to obtain them, to be placed in the public domain. Manufacturers should work with regulators to ensure that their products have undergone appropriate safety testing, and provide the relevant data regarding the health and environmental safety of their product.

Regulation should require the guiding principle of “No data, no market” to verify the safety of engineered food instead of “Release into the food supply first, assess risks later.”

DTW: What are the benefits of nanotechnology when used in all areas of agriculture?

DB: There are many, and more are being developed almost every day. A Cornell University team headed by textile scientist Margaret Frey developed a cloth farmers can use to reduce the amount of crop agrichemicals. Planted along with seeds, the cloth’s saturated nano fibers slowly release pesticides and herbicides so that additional spraying of crops becomes unnecessary. The targeted release also eliminates chemical leaching into the water supply to benefit both consumers and the environment.

Another pro is chicken feed to remove campylobacter — feed enriched by nano carbohydrate particles binds with the bacterium’s surface to remove it through the bird’s feces. When used in chickens, it might reduce the one million annual outbreaks of campylobacteriosis in America.

There are countless other applications being developed, including nanocapsules for delivery of pesticides, fertilizers, and other agrichemicals more efficiently, nanosensors for monitoring soil conditions and crop growth and for detection of animal and plant pathogens; and — according to developers — targeted genetic engineering to deliver trait-enhancing DNA to plants.

DTW: Is Nanotechnology being used in the development of a “new seed” replacing GMOs/GEOs?

DB: Novel genes are being incorporated into seeds and sold in the market. Research on “smart seeds” programmed to germinate under favorable conditions with nanopolymer coating (encapsulation) is underway. Tracking of sold seeds could be done with the help of nanobarcodes that allow electronic tracking.

Seeds are also using nanocoatings to prevent disease spread and seed death by pathogens while in storage. Nanocoating of seeds using nanoparticles (1 billionth of a meter, or 25,250,000th of an inch) of Zinc, Manganese, Protactinium, Platinum, Gold, Silver are said to be used in far less quantities than used today. A technique known as quantum dots (QDs) is a fluorescence marker coupled with immuno-magnetic separation for E coli 0157:H7, which will be useful to separate unviable and infected seeds.

DTW: If so, what are the environmental consequences of using Nano-seed in agriculture? Water usage and absorption? Soil integrity? and Waste?

DB: All of these excellent questions are unanswered because of lack of balanced, unbiased, long-term research. There is, however, an abundance of enthusiasm and publicity around studies that promote the new technology.

One example reported in Science News says, “With potential adverse health and environmental effects often in the news about nanotechnology, scientists are reporting that carbon nanotubes could have beneficial effects in agriculture. Their study found that tomato seeds exposed to CNTs germinated faster and grew into larger, heavier seedlings than other seeds. That growth-enhancing effect could be a boon for biomass production for plant-based biofuels and other agricultural products, they suggest.”

It appears that in our enthusiasm to embrace new, profitable research we discard common sense, which would dictate testing on organisms for at least a generation. Instead, it appears that these products are ushered into the marketplace without scrutiny as a fait accompli.

DTW: We also know that Monsanto had recently gotten a federal law passed, what is known as, The Dark Act which states that GMOs/GEOs are not required to be listed on the labels of food products; and has stripped the States of their power in controlling the farming of and labeling of GMOs/GEOs.   Since Monsanto is still not aware, or should we say the public is not aware, of the long-term ramifications from consumption of the food products – The Dark Act also includes a cap on damages should the public sue for the side effects from the consumption of GMOs/GEOs.

Would the Dark Act (Denying Americans the Right to Know) (DARK) Act include Nanotechnology or is it GMO/GEO specific?

DB: At this time, nanofood is flying below the radar and is not included in The Dark Act. In effect, it means manufacturers have a blank check to use nanotech at will in agriculture and in food. There are FDA guidelines, but they are toothless. Fortunately, there are organizations such as the Center for Food Safety who seek to establish a precautionary policy both at home and abroad to “safeguard human health and the natural environment.” They urge regulations that ensure transparent oversight and communication in nanotechnologies’ effects and social impacts.

DTW: Now that Bayer is in the last stages of acquiring/owning Monsanto Ag Business have you heard anything about their research heading into the direction of nanotechnology?   I ask because Monsanto had shied away from nanotechnology staying with GMOs/GEOs only.

DB: When Robert Shapiro (then CEO of Monsanto) was asked what he believed was the world’s most promising future technologies, he replied, “There are three, although I have a feeling that under some future unified theory they will turn out to be just one. The first is, of course, information technology …the second is biotechnology …and the third is nanotechnology.”

However, because many of the same criticisms of GMOs apply to nanofood, I believe Monsanto is indeed gun-shy about nanotech. That doesn’t mean they’re giving up on new bio-engineered foods. Far from it. Monsanto is putting its money on an even newer technology called CRISPR, or gene editing, which is reportedly more precise than GMOs. On September 22, 2016, Monsanto announced they had obtained the exclusive license to the CRISPR-Cas genome-editing technology from the Broad Institute at Harvard University and MIT. Like Nanofood and GMOs, CRISPR is being embraced without oversight.

DTW: Do you see the Nanotechnology industry being transparent so that public trust will be established?

DB: I believe I have previously answered that question.

DTW: Will the consumer learn what products have Nanotechnology use, i.e., the product packaging that used nanotechnology wrappings, etc.?

DB: Only if legislation forces them to label, which, as was previously addressed, is not likely to happen in the foreseeable future.

DTW: There is support for the use of nanotechnology in the food wrappers to detect/prevent spoilage for longer shelf life; but, what are other benefits from nanotechnology when used in foods?

DB: Other purported benefits for Nanofoods include the immediate detection of E. coli bacteria in a food sample; if Salmonella bacteria are present, for example, the nano-sized dye particles become visible. There is no need to send out to the lab and wait days for culturing results; improved solubility of vitamins, antioxidants, healthy omega oil fractions and other nutrients; nano-nutrient particles are fully soluble and invisible in water and oil, widening the door for potential nutraceutical beverages; nanobarcodes from nanoparticles that contain silver and gold stripes varying in width, length, and amount, create billions of combinations to tag individual products; barcodes have been primarily used to assure brand and authenticity in pharmaceuticals — applications are forthcoming that trace food batches; food technologists say food spreadability and stability improve as a result of incorporating multiple nano-emulsions — for example, a low-fat mayonnaise formulation provides a satisfying fatty mouth feel — extra stabilizers and thickeners aren’t needed to achieve the desirable texture. The nano-emulsion could have its application in formulating other low-fat products; and novel flavors such as cold and creamy based on a rethinking of how taste buds perceive flavor — researchers identified which individual cells on a given taste bud perceive a flavor. Each cell would recognize just one of the five main flavors — bitter, salty, sweet, sour and umami. One company has developed a library of flavors, including compounds called bitter blockers. These specialized molecules trick the tongue into not tasting the bitterness in foods such as cocoa or soy.

Farm to Table: The Essential Guide to Sustainable Food Systems for Students, Professionals, and Consumers

MM: “Farm to Table” is a concept and a descriptor that makes sense when you hear or read about it in context, but can actually be difficult to define by itself. What is the most succinct answer you know of to the question “What is ‘Farm to Table?’”

DB: If I see Farm to Table on a menu I’m going to expect fresh, nutritious, tasty food. How it arrives from the farm to your table involves a system — a collaboration between farmers, restaurant workers, purveyors, educators, and concerned citizens. The term implies a shorter chain in the food system, food grown locally or regionally, and, once harvested, goes directly to a chef, or perhaps one purveyor, before the customer consumes it. An eagle’s eye view of the term reveals the tectonic stresses in the struggle to achieve economic, political, social, and environmental sustainability, particularly at the corporate and governmental levels.

MM: A lot of the food system technologies and practices that we now know to be problematic—to health, to the environment, to the economy—were initially heralded as advances that would help humankind. What is an example of an old idea that seemed beneficial in theory, but has proven to have terrible consequences that now require correcting?

DB: When Henry Ford took advantage of the then-relatively new idea known as the assembly line, it revolutionized manufacturing. It did so by introducing efficiencies such as interchangeable parts, division of labor, and time savings that rocketed the bottom line — Model T’s sales – to astronomical heights. The problem is, you can’t apply assembly line thinking with such blanket authority to food production for the simple reason that living things — livestock and crops, for examples — are not the same as inanimate objects.  The Green Revolution was credited with saving a billion lives through such efficiencies, increasing yields to agricultural production never dreamed possible. But the consequences of producing “more” without the attendant necessity of “healthy” caused unintended problems of sickness, obesity, and lack of access that led to the establishment of the Fresh Food Movement, of which Farm to Table is a subset. The intent is to undo the damage of excessive pesticides, genetically modified foods, foods laden with fats, sugar, and salt by increasing the availability and accessibility of unprocessed, whole foods grown locally and harmoniously with nature. The assembly line paradigm is not how nature does business. That is not to say Farm to Table advocates want to turn the clock back. Instead, they embrace new ideas and technologies that supports these goals.

MM: What food system solutions being promoted/developed right now, may also turn out to create more problems than they solve?

DB: Nanofoods — or microscopic particles in food — are being promoted and developed with the same enthusiasm and abandon big agribusiness reserved for GMOs in the ’90s. Indeed, it seems history is repeating itself as scientific rigor is bypassed in favor of political exigencies. Inadequate peer-reviewed testing of long-term health effects of nano-sized metals and chemicals designed to enhance shelf-life, for example, or injected into packaging that can leach into food, are already in the food system. The tiny size of nanomaterials permits them to pass more easily through cell membranes and other biological barriers, allowing these particles to be easily taken up into organisms and potentially cause cellular dysfunction. Disturbingly, the policy appears to be “release into the food supply first, assess risks later.”

MM: Farm to Table is most often used in the context of a restaurant experience, but in your book you describe Farm to School, Farm to Hospital, and other sectors of the farm and food economy that are taking similar approaches to sourcing and marketing meals. Can you talk a bit of the relative importance of institutional dining in all its forms to the greater food system?

DB: In many ways, I see institutional dining as key to industrial food reform. Institutional food has gotten a bad rap — school food, hospital food, prison food – much of it because of highly processed food mandated by accountants who are trying to make ends meet on meager budgets. Farm to Table proposes solutions using local resources to cut costs while improving the quality of food, contributing to the economic growth of the community, encouraging food education (including students growing their own food in the “edible schoolyard”) and advocating for increased funding of institutional budgets.

MM: A lighter question—please tell us about a favorite memorable “farm-to” meal you’ve had: when, where, what, who, and why?

DB: On August 7 of this year I had the pleasure of attending the Vermont Fresh Network’s 20th Anniversary Forum Dinner. Imagine dozens of tents housing Vermont foods of astonishing variety by the shore of Lake Champlain on the rolling green hills of Shelburne Farm. There were hundreds of hungry, happy faces milling around sampling the cornucopia.  I started with tastings of Jasper Hill farm’s acclaimed Bayley Hazen Blue cheese and (several) smoked pork bánh mì sandwiches. Although there were many tempting beverages, such as Mad Fiver Bourbon and Shelburne Farms Duet Ice Wine, I didn’t think I would make it to the dinner entrées if I indulged. Speaking of dinner, an outstanding dish was presented by Michael’s on the Hill – chilled sweet corn soup with smoked Mountain Food Farm trout. I also greatly enjoyed New England Culinary Institute’s Willow Brook Farm tomato galette. A mouth-watering treat from Taverna Khione called Spetsofai (a Greek dish), smoked ShakeyGround Farm lamb sausage seasoned with orange zest and leeks, with a ShakeyGround Farm tomato, onion and pepper stew, finished me off. I could eat no more. I did something I rarely do:  skipped dessert. It was a deeply satisfying meal knowing how much care and attention went into every bite.

MM: What are some of your hopes for the U.S. (or global, if you prefer) food system in the near and long-term future, and what are some reasons for optimism?

DB: I feel encouraged when I see the public demand for GMO labelling. I am similarly heartened when I see or hear of Edible Schoolyard programs where young people are forging connections with the food they eat. Education is the heart of change; when I see consumers demanding real food I am hopeful their voices will be heard in D.C. and beyond. I am hopeful, too, that eventually we’ll come to our senses and separate corporate interests from political policy. The government’s responsibility to support and protect its citizens is at odds with corporate goals for short-term profits that fail to see citizens as people but instead sees them as consumers, or worse, commodities.

Here are two presentations by Darryl Benjamin, most recently held at the 2017 NOFA Summer Conference:

  Nanofoods Presentation – Darryl Benjamin

  CRISPR and Food Presentation – Darryl Benjamin

  1. Avoid engineered/fabricated food. Consumer choices send a strong message —75% of all processed food contains GMOs; corn, soy, and canola oil are 80%-90% GMO. Avoiding these products keeps your family healthy. Purchase organic; get your Non-GMO shopping guide; look for the Non-GMO Food Project label.
  2. Help pass legislative or ballot initiatives by spreading the word, collecting signatures, and donating. We have the right to know what is in our food!
  3. Talk to others — whether they’re friends, family or strangers — help educate! Hand out educational materials about engineered/fabricated food or place them where others will see it. Pass out educational material to your neighbors.
  4. Spread the word by sharing links through email or social media to educate your friends and family. Organizations like The Institute for Responsible Technology, GMO Free California, GM Watch, Millions Against Monsanto, Organic Consumer Association, and the GMO Truth Alliance all publish regular updates on social media and have mailing lists as well.
  5. Send out or share others’ Twitter feeds that help educate the public and remind them of the importance of putting an end to engineered/fabricated food.
  6. Seek audiences for educational talks or webinars through groups you already belong to, such as religious organizations, parent-oriented events, health, school, college and gardening related organizations, where these types of educational events are often welcomed.
  7. Invite friends and family members to watch a non-GMO movie such as The World According to Monsanto, Scientists Under Attack or The Future of Food.
  8. Read and recommend books about GMOs, such as Seeds of Deception or Genetic Roulette.
  9. Most, if not all, organizations fighting against GMOs or for GMO labeling are non-profit organizations relying on donations from supporters. Donate to these organizations — they could not do the work that they do without our financial help.
  10. Contact the food manufacturers you buy from and ask them if they use engineered or fabricated ingredients. Let them know that you will no longer buy their products if they do.
  11. Contact your local health food store or co-op and ask them if you can hand out educational materials to their customers.
  12. Contact your local newspapers, magazines or any media with educational articles, letters or videos.
  13. Get a booth at a local event or Farmer’s Market and hand out educational material. Help educate your local healthcare professionals about the dangers of engineered/fabricated food and why they should recommend a diet that avoids these foods.
  14. Contact your government representatives, including the president, and let them know that you want to end engineered/fabricated food. Sample letters will be available on our website soon.
  15. Keep in touch with other sustainable food organizations for updates, such as the Center for Food Safety, Friends of the Earth or GM Watch.
  16. Volunteer to help at local events that promote sustainable food that is not genetically altered or artificially fabricated.
  17. Grow your own Non-Engineered Food.
  18. Petition your local schools to serve real food.
  19. Ask the grocery store chains to label all engineered/fabricated food and to stop selling engineered/fabricated food.
  20. Take Care of Yourself! Taking on a huge industry that is tied to our government can feel overwhelming. Make sure you spend time nurturing your body, mind and spirit.
  21. Get Involved and Get Active! Contact the organizations listed above and attend local events featuring real food alternatives to engineered/fabricated foods.


Darryl and Sigrun recently attended the 5th International Food Studies Conference in Blacksburg, Virginia. During the conference, they conducted a workshop on Nanotechnology in Food Systems, which was very well received. Since there was so much interest and enthusiasm about this topic, we decided to make our presentation available to all attendees well as other interested parties.

Please contact us if you have any questions, or if you are interested in a workshop, seminar or presentation by the GMO Breakthrough Education Project.


The GMO Breakthrough Education Project will be offering a workshop at the Fifth International Conference on Food Studies in Blacksburg, VA on September 19: http://cgpublisher.com/conferenc…/…/proposals/247/index_html
