News that President-elect Donald Trump is considering U.S. Rep. Mike Pompeo for a cabinet slot illustrates just how dark the days ahead might be for America’s burgeoning “food movement,” which has been advocating for more transparency and fewer pesticides in food production.

Pompeo, a Republican from the farm state of Kansas, was the designated hitter for Monsanto Co. and the other Big Ag chemical and seed players in 2014 when the industry rolled out a federal effort to block states from mandating the labeling of genetically modified foods. Pompeo introduced the “Safe and Accurate Food Labeling Act” in April of that year with the intention of overriding bills in roughly two dozen states.

In bringing the bill forward, Pompeo was acting on behalf the Grocery Manufacturers Association (GMA), which represents the interests of the nation’s largest food and beverage companies. The bill, which critics called the “Deny Americans the Right to Know” Act, or the “DARK Act,” went through two years of controversy and compromise before a version passed and was signed into law by President Barack Obama this summer. The law nullified a mandatory labeling bill set to take effect in Vermont in July of this year, and it offered companies options to avoid stating on their packaging whether or not a product contained GMO ingredients.
