Will Reducing Food Waste Be Sufficient Reason To Embrace GMO Produce? Cornell Professor Brad Rickard To Guide A Controversial Session At The London Produce Show And Conference 

Jim Prevor’s Perishable Pundit, May 12, 2015

Brad Rickard is a rising star on the Cornell faculty, and he consistently delivers world-class presentations that take knowledge developed through intensive academic research and disseminates that knowledge to the industry where it can alter professional practices.

He has often presented at The New York Produce Show and Conference, providing valuable insights in presentations we profiled in pieces such as these:

Q: We’re so pleased you’ll be speaking at the London Produce Show and Conference this year. Your standing-room-only presentation at the New York Produce Show examined the potential impacts of commercialization of GMO fruits and vegetables, and consumer acceptance of different GMOs products. It generated a flurry of industry discussion long after the show ended. With GMO news continuing to make headlines, will you be sharing more on this topic across the pond?

A: Actually, I’m taking a different angle, so it is mainly about food waste as it connects to the GMO debate. I’ll look at the role of information/date labels on food waste; the potential role of technology, including GMOs on food waste; and, more generally, the effects of positive and negative information on consumer acceptance of GMOs.

Q: How do the issues of food waste intersect with GMOs?

A: It might be best to treat this as extension of what I talked about at the New York Produce Show, thinking about consumer response to GMOs — in particular GMOs for fruits and vegetable products.

Q: Since your studies involve U.S. consumers, is it important to frame this discussion in the context of the U.S. market, versus UK and European markets?

A: There’s this general question about consumer acceptance of GMOs, and most of what I’m talking about is in the U.S. However, with the deregulation in the U.S. of Genetically Engineered technology for apples and potatoes, it makes us wonder: What is the future for GE technology in fruit and vegetables markets? This issue is global in scope.

We see a prevalence of GMOs in corn and soybeans in the U.S. and various other countries, but we haven’t really seen GMOs in fruits and vegetables outside of a few examples -- genetically modified zucchini and squash varieties, Hawaiian papaya, and some sweet corn, engineered for virus- and pest-resistance, but nothing widely commercialized.

Q: Isn’t there a lot of work on GE fruits and vegetables being done behind the scenes?

A: Scientists are working with GMOs in other fruit and vegetable crops but haven’t done it on a wide scale. There’s the genetically modified Arctic apple that doesn’t brown, and a Russet potato genetically engineered to resist bruising, both recently deregulated in the U.S., and people are wondering about the commercial potential and whether that will lead to further deregulation of other GMO fruits and vegetables.

Q: You’ve tried to weight potential causes for why genetically engineered produce is practically non-existent on retail shelves—a void in industry research, regulation bottleneck, and consumer resistance. Based on your research, you’ve leaned toward the latter as the main culprit. Do you think things are changing?

A: Why haven’t we seen more GE technology in produce markets? A nice piece in Nature Biotechnology explores that question. Some wonder if there isn’t enough research done. In actuality, there is quite a wide range of research done, with scientists conducting experiments for various fruit and vegetable crops in many countries. The U.S. is the leader, but also in China, Japan and several European countries. We see it for potatoes, tomatoes, apples, oranges, lettuce, carrots, eggplants, pineapples and bananas. Many studies are being done on the technical aspects of GMOs for fruits and vegetables.

Q: How valid is this research? What are the findings?

A: What are the benefits of these experiments? Much of it is focusing on the production side -- yields and the quality of the products. In some cases, these crops are bio-fortified. They’ll have heightened content of vitamin A or B or E.

The tricky part is these crops are being explored by scientists in a lab, but not available in consumer settings to determine whether they’re valued. We did experiments on what characteristics are important to consumers, which I’ll discuss in more detail in London.

So in addressing the reasons why we see little GMOs in fruit and vegetable markets, we know research is being done for various produce specialty crops in field trials. The second reason might be government regulation. That could be a factor, relative to the number of commodity crops that have been approved. We have seen GMO apple and potato varieties deregulated very recently in the U.S. Maybe this signals a swing in momentum.

Q: What’s happening in Europe on that front?

A: In the EU, it’s different across member states. France and Germany seem to be stricter in approving GMOs, and places like the Netherlands and Spain seem more open to deregulating more crops. There is a surprising amount of GMO corn grown in Spain, which leads the EU in GMO crop production and field trials. The UK seems to be more open as well.

Q: Aren’t there some promising genetically engineered produce varieties making headway in the government regulatory process, such as the purple tomato and the pink pineapple?

A: Genetically modified purple tomatoes developed at the John Innes Centre in Norwich, UK, may be gaining ground in the approval process for sale on British retail shelves. Right now, I believe they are in large-scale production for purple tomato juice in Ontario, Canada. The GE purple tomato is bio-fortified with elevated levels of certain compounds also found in blueberries and cranberries that have health benefits. It’s another example of GMO technology that exists. But it hasn’t been approved in the U.S.

Q: Will a focus on developing GE products with nutrition and health attributes help drive the process forward?

A: The purple tomato perhaps has a better chance of approval in the U.S. because of its consumer benefits. Similarly, Del Monte engineered a pink pineapple, another example of a GM product with bio-fortified properties. The pink pineapple, with heightened levels of some antioxidants, is pending FDA approval. These are very new developments.

Breaking down barriers for reasons one and two, my story is the third one, consumer acceptance, which might be the sticking point.

Q: Would you say that’s exemplified by the flurry of GMO labeling bills appearing on numerous state election ballots in the U.S., and the growing influence of anti-GMO groups?

A: We’ve seen GMO referendums in California, Washington and Maine, and plebiscites in Colorado and Oregon. The takeaway… there are heated debates, for and against arguments voiced very loudly. Generally, the referendums have failed, the majority voting against GMO labels in California, Washington, Colorado and Oregon. In some small states, including Connecticut, Maine and Vermont in the Northeast, GMO labeling bills passed, but they haven’t been implemented yet.

Q: Why the delays?

A: They need to have critical mass of more states on board before these states will act. Also there are legislative concerns of states enacting their own referendums with varying standards.

Consumers willingly purchase genetically modified corn and soybeans. On the other hand, when you ask consumers what they think of GMOs, they express resistance. Now a bill in New York State is up for discussion. If you label with a GMO sticker, it forces companies to segregate ingredients. They will have to pass those costs on to consumers, which may increase their grocery bill $400 or $500 a year. That influences swing vote consumers.

Q: So in the end, it may come down to shoppers’ pocket books? Is it possible consumers don’t realize the GMO ingredients are in products they’re purchasing?

A: We have research consumers are more concerned with raw product they consume directly.

One more thing, how consumers accept GMOs in the U.S. versus the EU is worth discussion. There are differences. Maybe among member states, you’ll see preferences, with consumers more or less willing to accept GMOs. More broadly, though, I’m not sure these differences apply to fruits and vegetables.

Q: Is there evidence to support that?

A: There are some interesting statistics coming out of a study done by economists published in the European Review of Agricultural Economics: “Effect of Information about Benefits of Biotechnology on Consumer Acceptance of Genetically Modified Food,” based on evidence from experimental auctions in the United States, England, and France.  The surveys in the U.S. focused on three states: Texas, Florida and California. In one of their summaries, consumers in all three states were relatively willing to consider purchasing food using GMO ingredients. This did not include fruits and vegetables. For their initial acceptance, consumers in Texas were most willing, then Florida, then California. The difference between England and California was very small. Then France was considerably lower.

On a scale from one to nine, with nine most willing, Texas and Florida were 6, California and England were 4.5, and France was between 3 and 3.5.  It’s one of the most sited papers in agricultural economics. It involved a combination of several authors, some from the U.S., some from Italy, some from New Zealand, and one from the University of Redding in the United Kingdom.

Q: This is a good segue to your fascinating research, which is able to differentiate consumer acceptance of GE food products based on category and characteristics. In doing so, you reveal a stark contrast between consumer acceptance of GMO ingredients in processed food products, for instance, versus genetically modified fresh fruits and vegetables…

A: I’ll say something in my London talk about this paper I did with colleagues Dr. Brandon McFadden, University of Florida, and Dr. Jayson Lusk, Oklahoma State, published in Biotechnology Journalin a piece titled: “Which Biotech Foods are Most Acceptable to the Public?

For the research, we surveyed 1,100 consumers in the U.S. on their level of enthusiasm for GMO grains, fruits and vegetables, and meat; how they feel about GMOs, both in fresh and in more processed versions. Our findings were similar to our hypothesis. Consumers in general had some willingness to accept GMOs, but it was much greater for processed varieties than fresh — apple sauce versus fresh apples, corn chips versus corn on the cob. Also, they were most willing to accept GMOs in corn and grains, second fruit, and third meat. Resistant to GMOs in meat products was greatest, and it was somewhere in between for apples. That was the primary objective and finding in that paper.

Q: Did you get consumers to discuss the factors that would sway them to purchase genetically engineered products? For instance, if they knew the produce variety was bio-fortified with health benefits…

A: At the London Show, I’ll also talk about a survey we did at the end of the study. We asked: What would be reasons that would make you more accepting of GMO technology? This is interesting because we try to get an idea of what product characteristics are most important to consumers. Some GMO crops have clear benefits to farmers. The first-generation crops in the 90s had real benefits for farmers. Now we’re seeing a lot more research on second-generation GMO crops on attributes much more focused on the consumer.

In this survey I did with Brandon and Jason, we gave consumers different motivations in their food choices more generally. If the product had more consumer benefit, they were much more likely to try or accept GMOs in the food. If the product increased farmer yields and efficiencies, or protected the product from insects or disease, consumers weren’t motivated. But if it improved nutritional content, or reduced food waste, those were reasons they’d consider buying GE product.

Fruit and vegetable experimental work seems to focus on improving nutritional content of food. A lot of these crops, especially this apple and potato deregulated in the U.S., can show as part of their message that they will reduce food waste.

Q:  That seems an important point. Food waste has become a massive and complex issue, at a time when sophisticated global initiatives and widespread campaigns are under way to create consumer awareness and combat the problem.

A: This is a central message: What are characteristics to reduce food waste? Improve the quality of the product either in the transportation, processing or the shelf life stage. This GMO potato, which has been approved for sale in the U.S., can withstand rough and tumble during transportation, doesn’t bruise as much in processing, and is much more resilient, which in turn translates to less waste. With the Artic apple, once it’s cut, it doesn’t brown like a typical apple with oxidation. It’s not a new variety.

Part of their public relations effort should be that less of the product is wasted, and it has a much longer shelf life. Thinking of apple slices, more common in foodservice and with children, eliminating the browning effect also should lead to less food waste.

Then there’s a whole host of other GMO products -- varieties with heightened nutrition and bio-fortified like iron, and Vitamins A, C, and E. This is even more important in developing countries.

Q: What happened with Golden rice?

A: It’s difficult to know. Golden rice as a product, with heightened levels of Vitamin A, hasn’t’ been successful commercially, even though it’s been around a long time, because of consumer resistance to the technology, and that resistance can be found anywhere in the world.

Golden rice was designed mostly for developing countries, and the hope was it would be grown in developing countries with acceptance and commercialization of GMOs.

There is still a lot of research being done on these bio-fortified crops. At my presentation, I’ll reference an article in Nature Biotechnology  in January, 2015, which provides additional perspective on the status and market potential of transgenic bio-fortified crops. It goes way beyond Golden rice with items such as broccoli fortified with Vitamin E.

Q: This brings us back to the intersection of food waste and GMOs and sets up the foundation for your talk. When you’re addressing attendees in London, what is the key message you want to impart? Will you be able to share some of your new research looking more closely into the issue of food waste?

A: I want to emphasize in my UK talk that consumer acceptance is the main reason why we haven’t seen more GE fruits and vegetables. Experiments are underway now around the world, focusing on consumer value propositions, bio-fortified products and reduction of food waste. There is so much concern with food waste. The UK, in particular, is in the forefront of ways to reduce food waste. In a lot of the GMO research I’m reading, the genesis of policy discussions is related to food waste.

I have some early results on research I’m doing on food waste. I’ve got this new project looking at food waste, how and why people waste food, and what can be done to minimize food waste.

The study is in two phases: First, how do consumers respond to information about food waste, related to food labels. The second phase is how consumers respond to technical innovations in packaging and in the introduction of GMOs.  

I really only have results for the first phase — how are consumers thinking about information? But I’ll be able to speak about the second phase.

Q: Can you give us more perspective on what’s involved in the research?

A: We ran an experiment where we brought people into a lab and asked how much they were willing to pay for a product and what percentage of the product will be consumed in their households. When scientists think about food waste, they get an idea of the value of the product not consumed. Perhaps the better measure is instead of quantity, the willingness to waste; the probability of throwing away some of the food. It’s rough, but it is a pretty good proxy of measurement of food waste.

We do this for three products, breakfast cereal, salad greens, and yogurt. We also do it for two different sizes, small and large of each category. Some people are exposed to a “use by” label, some are exposed to a “best by” label, some to a “fresh by” label, and some to a “sell by” label. Everyone sees those three products in both sizes, and different people are exposed to those different treatments of those labels.

Q: You’ve hit on a controversial topic here, fraught with confusion…

A: There’s a lot of debate on these labels, all of which are sort of confusing to consumers. A lot of food is wasted because we misunderstand these labels. If it says “use by,” there’s some hint that it has something to do with food safety, when in reality it doesn’t have anything to do with it. If it says “fresh by,” it’s associated with food quality, but not necessarily food safety.

None of these labels are really regulated in the U.S. Different states have different interpretations, but no legal meaning. For the most part, packaging leads to confusion with no consequences on the food manufacturers or the retailers.

The truth of it is, a lot of these products are safe well beyond the label, and it’s really just a food quality or inventory tracking scheme. A lot of people who think about this really carefully realize this is a major driver of food waste in the U.S. Up to 30 to 40 percent of food is wasted in the U.S. Part of this could be due to food labels, while others feel it should be harmonized and consistent.

Q: In your research, what label created the most potential for food waste? And what label would best reduce it? Did it differ based on the type of product?

A: The punchline: The level of waste is highest when the label says “use by.” The amount is lowest when it says “sell by.” What I just described is true across all the different products. But most true in salad and yogurt.

The interesting thing… in the salad category, there’s quite a bit of waste when consumers see a “use by” date, but still quite a bit of waste when they see a “fresh by” label. In reality, we don’t see that label much, but we included it because consumer advocates think “fresh by” is a better label to use. “Best by” and “fresh by” had a surprising amount of food waste, and “sell by” the least.

“Use by” is more of a food safety label where “fresh by” is more quality label. This willingness to waste in the salad category seems to indicate product quality is a pretty important consideration in the salad category.

Q: Where will your research take you from there?

A: What we want to do next is see how consumers would respond to new technologies that have benefits in food waste. Most of these second generations are to improve food quality, whether packaging technology or GMO technology. Will it be accepted, and at what kinds of acceptance levels, and what impact will it have on food waste?

We’ve been reading about the sale of “ugly fruit” as a way to reduce food waste. It’s something we might be able to get at in this subsequent experiment. It’s an extension of food quality, how consumers think about food safety versus food quality. It’s a good time to present this topic to this audience. Instead of ending with an answer, my hope is to create a stimulating discussion and end with questions.

We started this research in December last year, with the building blocks. A lot of things are going on here. There is some link between consumer acceptance of GMOs, with food waste as part of a promotional campaign. It could be GMO advocates know food waste is a big topic so they’re using it as leverage, but if consumers are concerned about food waste, one seems to be a solution to the other.


Steve Jobs was dismissive of consumer research. He liked to quote Henry Ford who famously said that “If I'd have asked my customers what they wanted, they would have told me ‘A faster horse.’ “

So asking consumers if they would like GMOs or what attributes would make them like GMOs is challenging work because it is hard for consumers to imagine things that don’t exist.

Not to mention that these things inevitably sound dangerous and, even, crazy. Imagine telling people who have never even seen an airplane that you are going to create giant tubes of aluminum and fly billions of people through the air in these tubes. One suspects volunteers wouldn’t necessarily report as enthusiastic to hop on board in surveys.

Barring political intervention, the outcome is clear. Although consumers may report that they are not motivated by, say, farmer benefits such as higher yields, when they see identical products available for much lower prices — because of those higher yields — they will buy them anyway.

Consumers may report that they are indifferent to farmer’s struggles with insects or disease but, if, due to disease such as the Papaya ringspot virus, there is no more Hawaiian papaya save the GMO type, they may decide to buy what is available. Same thing with Florida citrus

To say that consumer resistance to GMOs is a big obstacle is not the way we would phrase the problem. Many stores carry Kosher, Halal or ethnic sections that are only purchased by a small percentage of the store’s traffic.

So it is, quite obviously, not necessary to have broad product acceptance to gain access to supermarkets. Whatever doubts consumers might have with GMOs, we would normally expect such products to gain placement and, with time, win market share if they offer desirable a tributes such as better pricing, nutritional benefits or reputational benefits as Professor Rickard alludes to in relation to food waste.

The problem is not consumer resistance to GMOs. The problem is that highly activist opponents of GMOs can dramatically change the cost/benefit analysis when a supermarket CEO looks at carrying GMO produce.

One variety of apples is an infinitesimal part of supermarket sales. So no increase in sales will possibly compensate for the loss in sales that can come about as a result of picketing and other forms of protest.

Consumers have extremely low incentives to research things such as this, and both production- and sell-side executives in the food industry have seen how easily a small but vocal group can tarnish the reputation of a harmless product such as lean finely textured beef, which is pejoratively known as “pink slime.” Retailers saw that they were at reputational risk from being associated with products that activists target.

So, a good market could exist to sell consumers GMO fresh produce, and retailers may never take the risk. The issue is not consumer resistance; it is retail resistance due to the small benefit of selling these items versus the enormous risk of being attacked by activists regarding these items.

So the real question is: Can any set of positive attributes appease activists who might otherwise  intimidate retailers? We doubt it. We are dealing with people who will be criminals to achieve their goals. In the Philippines, two anti-GMO groups destroyed the work of academics studying Golden rice as detailed in this piece, titled Activists Destroy ‘Golden Rice’ Field Trial. The idea that they will be persuaded because GMOs may reduce food waste strikes us as unlikely.

This will surely be a robust discussion. European sensibilities and institutions are strongly anti-GMO, but if new GMO varieties are more productive or offer other advantages, then European production agriculture will either go with GMOs to compete or be relegated to a protected domestic market.

We can’t wait to learn from Professor Rickard and be part of what promises to be a most interesting session.
