Recent reports of secret meetings among industry reps and the Food and Drug Adminstration over GMO labeling piqued my interest, mostly because this critical aspect was missing: any effort to label GE foods at the federal level could bring the current grassroots movement to a grinding halt by preventing any stronger local laws from ever being enacted. But I am getting ahead of myself.

Last month, Ronnie Cummins, director of the Organic Consumers Association and one of the leaders of the GMO labeling effort, recently published an article about how “representatives of Wal-Mart, General Mills, Pepsi-Frito Lay, Mars, Coca-Cola and others” met with the FDA on January 11 “to lobby for a mandatory federal GMO labeling law.”

The story was then picked up by Tom Laskawy at Grist, who reported that at the meeting, a Walmart representative said the retail giant would no longer oppose GMO labeling and that “[o]ther food company executives agreed, saying that the fight had become too expensive, especially given the prospect of more state-level initiatives.”

The story kicked into high-gear when the New York Times’ Stephanie Strom covered it last week, adding a few new details, such as the meeting being attended by “20 major food companies” as well as two GMO labeling advocates: Gary Hirshberg, co-chair of the Just Label It federal campaign, and Charles Benbrook, professor at Washington State University. The Times story gave the impression that the meeting is something to celebrate. After all, if Walmart comes to the table, that’s a big deal.

But missing from both of these accounts is the ominous potential downside of federal GMO labeling: a sneaky legal concept known as preemption. Most advocates don’t find out about it before it’s too late.

Preemption simply means that a higher law trumps a lower law: so federal trumps state, and state trumps local. But in practice, it’s industry’s way of ensuring uniformity and stopping grassroots efforts. How I do know this? From years of experience of seeing it happen in various public health issues. It’s such a huge problem that the Robert Wood Johnson Foundation funded an entire project called “Preemption and Movement Building in Public Health” to educate advocates about how to handle it.

Here is the pattern: a grassroots effort builds over time to enact local or state laws (such as gun control, indoor-smoking laws, or restricting alcohol sales), and industry fights these efforts for years, until they can no longer win. At that point, industry lobbyists turn around and either get their own weak bill passed, or work with advocates to pass a compromise version. In exchange, this law will preempt or prevent any state or city from passing a different or stronger law. Forever.

No industry likes to deal with 50 different state laws, or even a handful of expensive state-level battles. We recently saw this exact scenario play out in the food movement, with menu labeling in chain restaurants. For decades, the restaurant industry successfully fought federal efforts to require calorie counts and other basic nutrition information on menus. Then over the last few years, numerous states and cities started enacting their own laws, much to industry’s dismay. Enter the compromise struck between the leading proponent of  menu labeling, the Center for Science in the Public Interest, and the restaurant industry: federally-required menu labeling for calories only, in exchange for all state and local laws being preempted, past and future. (See this document labeled “compromise endorsements” for the bill’s supporters, which include the Grocery Manufacturers Association, a leader of the No on Prop 37 campaign on GMO labeling in California.)

Now, almost three years after passage, we still don’t have federal menu labeling as the final regulations are stalled at FDA, while certain industry members fight it. We also no longer see states or cities taking up the issue, figuring the feds took care of it. See what I mean about stopping a grassroots movement in its tracks? Public health lawyer Mark Pertschuk noted: “the rapidly growing grassroots movement for meaningful menu labeling may never recover.” He also cites the irony of this 2009 memo from President Obama opposing preemption in all federal rule-making. The memo correctly notes: “Throughout our history, state and local governments have frequently protected health, safety, and the environment more aggressively than has the national government.”

Amen to that. I am not opposed to federal labeling on GMO food. I agree this is where the problem must ultimately be solved. However, any federal standard must set a floor and not a ceiling, and not hand preemption over to industry. The role of the federal government is to set minimum standards, while still allowing states to go further. This, however, is not the end-game that Walmart et al. have in mind.

I asked Dave Murphy, founder of Food Democracy Now! and leader of the grassroots GMO labeling efforts about this issue. He told me it was a huge concern among movement leaders: “Ultimately the conversation represents a seismic shift in where we were four years ago on GMO labeling. But we know that anything coming out of Washington D.C. will be a weaker standard, which would not be good for either farmers or consumers. The goal is to make sure that a federal law doesn’t undermine state efforts.”

As Cummins noted about the meeting: “We should be wary of any compromise deal at the federal level, one that would preempt the passage of meaningful state GMO labeling laws that have real teeth.”

Very wary indeed.
