By all accounts, Americans want a more transparent food system. Recent polling suggests the majority of Americans favor labeling that tells them exactly how and where their food is produced. And yet, several bills are currently moving through Congress that could make it much harder to learn about the source of our food.

These bills would prevent state and local governments from requiring labeling of GMOs; remove country-of-origin labeling (COOL) requirements for most of the meat we buy; and make it harder to know where pesticides are used. The international trade agreements now being negotiated also include provisions that could make such information less available to consumers.

The food industry is spending an enormous amount of money to promote and lobby for this legislation. Food companies may have shelled out over $100 million* in the first six months of 2015 alone, according to federal lobbying disclosure reports.

Businesses and trade groups promoting these policies say putting more information on food labels will send the wrong message about food safety, add costs, and pose barriers to trade. And in some cases, they worry it will open U.S. food producers and other companies to punitive import-export taxes.

But good food advocates disagree. “This is basic transparency,” says Patty Lovera, assistant director of the advocacy group Food & Water Watch. “We’re not saying anything’s unsafe,” says Environmental Working Group (EWG) policy analyst Libby Foley. “We’re saying it’s about consumer choice.”

Here are the numbers the food industry doesn’t want you to see:

GMO Labeling

So far this year, food and beverage companies have spent $51.6 million on a series of lobbying including efforts efforts to defeat GMO labeling laws such as the Safe and Accurate Food Labeling Act of 2015 (H.R. 1599), which opponents have dubbed the “Deny Americans the Right to Know” or DARK Act. According to a recent analysis by EWG, nearly a quarter of this money—$12.6 million—comes from just six companies: Coca-Cola, General Mills, Kellogg’s, Land O’Lakes, and PepsiCo.

Other big spenders in these efforts include the Grocery Manufacturers Association ($5.1 million); American Farm Bureau (nearly $1 million); and the National Restaurant Association ($2 million). Many state farm bureaus have also chipped in—among them, Alabama, Florida, Iowa, Kansas, Missouri, Michigan, Minnesota, Nebraska, New York, North Carolina, and Oregon. Big name food producers, including Campbell Soup, Mars, Inc., Mondelez, Nestlé, OceanSpray, Safeway, and Unilever, are all spending significant amounts money on this issue as well.

In addition to direct lobbying of members of the House, Senate, and other federal policy-makers, some of the groups lobbying for H.R. 1599 have come together as the Coalition for Safe Affordable Food, running a consumer-oriented website, as well as television ads and a social media campaign. And the money tallied by EWG was spent specifically on federal lobbying so it doesn’t include the millions spent last fall to defeat state GMO labeling measures—like those in Colorado and Oregon or on the ongoing legal challenge to the GMO-labeling bill passed in Vermont.

H.R. 1599 passed the House on in July. No companion bill has yet been introduced in the Senate.

An additional $4.1 million has been spent so far this year by companies to promote genetically engineered salmon, with most of this coming from the Biotechnology Industry Association, which is also supporting H.R. 1599. There’s also plenty of lobbying going on to keep GE salmon out of Pacific coast waters, where salmon fishing is big business.
