They also gathered to relish their changing political fortunes, courtesy of the Obama administration.
“This has never been just about business,” said Gary Hirshberg, chief executive of Stonyfield Farm, the maker of organic yogurt. “We are here to change the world. We dreamt for decades of having this moment.”
After being largely ignored for years by Washington, advocates of organic and locally grown food have found a receptive ear in the White House, which has vowed to encourage a more nutritious and sustainable food supply.
The most vocal booster so far has been the first lady, Michelle Obama, who has emphasized the need for fresh, unprocessed, locally grown food and, last week, started work on a White House vegetable garden. More surprising, perhaps, are the pronouncements out of the Department of Agriculture, an agency with long and close ties to agribusiness.
In mid-February, Tom Vilsack, the new secretary of agriculture, took a jackhammer to a patch of pavement outside his headquarters to create his own organic “people’s garden.” Two weeks later, the Obama administration named Kathleen Merrigan, an assistant professor at Tufts University and a longtime champion of sustainable agriculture and healthy food, as Mr. Vilsack’s top deputy.
Mr. Hirshberg and other sustainable-food activists are hoping that such actions are precursors to major changes in the way the federal government oversees the nation’s food supply and farms, changes that could significantly bolster demand for fresh, local and organic products.
