The Wall Street Journal Highlights The GMO Dilemma
Will the 'Innate' Potato Change Minds When The Case Is So Clear?
Don’t Bet The Farm On It!

Jim Prevor’s Perishable Pundit, November 12, 2015

The opposition to GMOs has always been rather surrealistic. One can, of course, imagine that any scientific tool could have adverse consequences. But the “law” of unexpected consequences is not the “law” of bad consequences – and there is no particular reason to think that, on balance and in the long run, GMOs will be a negative for the world or for human civilization.

The particular oddity about blanket opposition to GMOs is that genetic modification is just a tool; it can be used in many different ways. Certainly one can argue that certain products of genetic modification are not desirable, but to argue that the technology is always bad is to argue that test tubes are always bad because they can be used to mix poisons.

Dr. Henry I. Miller was the first director of the FDA’s Office of Biotechnology and now is a Research Fellow at Stanford University’s Hoover Institution. He wrote a piece for The Wall Street Journal titled, Stuck in a Regulatory Mash-Up, and subtitled, “A genetically modified potato could combat blight and cut fungicide use—if the FDA and EPA will let it”:

In the new film “The Martian,” an astronaut stranded on Mars grows potatoes to subsist until help arrives. Nutritious and filling potatoes were a good choice: A 5.3-ounce baked potato has 110 calories, more potassium than a banana and almost half the recommended daily value of vitamin C—with zero fat.

The potato is getting even more remarkable thanks to modern genetic engineering. A variety that resists blight—potentially obviating the need for thousands of pounds of chemical sprays every year—is coming. But standing in the way has been dilatory and superfluous regulation by no fewer than three federal agencies.

Late blight, an infection by the water moldPhytophthora infestans, is what caused the infamous Irish potato famine in the 1840s. Wet weather patterns on the Emerald Isle gave rise to massive outbreaks of the fungal disease, which is spread by wind currents and rain. Potato crops rotted in epic proportions. Left without their staple crop, an estimated one million people starved to death. A million more left the country in search of food.

More than a century and a half later, late blight is still a major problem for farmers. In most places it can be controlled with fungicides, which are commonly sprayed as often as 15 times a season. This summer was particularly bad for late blight in Michigan, Idaho, Pennsylvania and Wisconsin, wiping out crops and sending farmers scurrying for the fungicides.

But a wild variety of potato from the Andes mountains displays natural resistance to certain strains of late blight. Geneticists at Simplot Plant Sciences introduced a gene from this variety into ordinary Russet Burbank potatoes to create the second generation of the company’s “Innate” potato. Simplot says in its petition for regulatory approval from the Agriculture Department that the new potato should provide American farmers relief from the most pervasive strains of late blight. That means it could reduce fungicide use by 495,000 pounds annually, according to Joe Guenthner, a 30-year potato-research veteran and professor emeritus at the University of Idaho.

As a bonus, Innate potatoes—both the new version and the first generation, which is currently on the market—are bruise-resistant. Simplot estimates that widespread adoption could reduce waste by producers, shippers and retailers by 240 million pounds annually. It could also make a dent in the estimated three billion pounds of potatoes discarded each year by consumers. Innate potatoes also contain lower levels of asparagine, an amino acid found in all potatoes that can turn into a probable carcinogen when heated to high temperatures. If ever a potato deserved “out of this world” status, this is it.

After a 17-month review, the USDA in August finally signed off on the second-generation Innate potato, the one with blight resistance. The USDA review ensured that the potato is not a plant pest and will not adversely affect other plants or the environment. Simplot’s 199-page application contained two years of data from field trials around the country to demonstrate that a potato plant that contains only potato genes performs, well, like a potato.

But the blight-resistant potato still needs the blessing of the Environmental Protection Agency and the Food and Drug Administration. The FDA safety review—which is theoretically voluntary, although companies don’t dare go to market without its seal of approval—will ensure that there are no significant differences in nutrition or other health-related factors between the new genetically engineered variety and its conventional counterpart. That review has been pending since April 2014.

The EPA claims authority to review the potato under the aegis of the federal pesticide statute, because the potato contains a “plant-incorporated protectant.” This risible policy lacks any basis in either science or common sense; the pesticide legislation was intended to regulate toxic chemicals. Nonetheless, Simplot expects to submit its application to the EPA later this month.

Interestingly, none of these regulatory reviews, by the USDA, FDA or EPA, would have been required if the genetic modifications had been performed with less precise, less predictable older methods that move large numbers of genes—such as irradiating seeds to mutate them or moving genes from one species or genus to another by hybridization—instead of state-of-the-art molecular techniques. If you think this makes no sense, you’re in agreement with the scientific community.

The length of time required for these regulatory reviews is absurd. What makes me an expert on approval times? I led the FDA team that examined early bioengineered drugs. In 1982 we were able to review and approve genetically engineered human insulin, the very first drug made with recombinant DNA technology (or “gene splicing”), in five months.

Bringing a new biotech crop to market, from inception to product introduction, takes on average 13 years and more than $130 million, according to a 2011 study for CropLife International. A more scientific approach to regulation could shorten that pipeline, putting important new products like the Innate potato into fields (and onto tables) much more quickly, reducing waste, cutting the use of chemical sprays and limiting consumption of a naturally occurring carcinogen.

Congress ought to act—but I’m not betting the farm on it.

This happens to be an almost perfect example of the follies in opposing all biotechnology. There is a lot of controversy over arcane issues, such as if you put a gene from a pig in another animal or plant – is that item no longer kosher? If you put a gene from a peanut in another plant, is it possible an unsuspecting consumer might be allergic to this other plant because the consumer is allergic to peanuts?

In the case of the Innate potato, however, genetic modification is being used solely to move potato genes from one potato to another – to do exactly what hybridization does but quicker and more accurately.

As Dr. Miller memorably puts it: “Simplot’s 199-page application contained two years of data from field trials around the country to demonstrate that a potato plant that contains only potato genes performs, well, like a potato.”

Prejudice against DL GMOs is pervasive, and politicians who know better find it advantageous to pander on this point rather than attempt to educate the populace.

In the end, though, this powerful tool will overcome all opposition, and those countries that choose to isolate their agricultural sector from the technology will become backwaters, unable to compete without the higher yields and specialized products that genetic modification will create.
