Eva Longoria is shining a spotlight on farm laborers in the United States…

The Mexican American actress and former Desperate Housewives star is hoping to push the plight of farm laborers to the top of the U.S. policy agenda with the release of Food Chains, an activist documentary that she executive produced.

The doc had its world premiere on Monday during the Berlin Film Festival‘s Culinary Cinema sidebar.

Food Chains, directed by Sanjay Rawal, follows a group of tomato pickers in Florida – the Coalition of Immokalee Workers – who take on the $4 trillion global supermarket industry.

Longoria has long been an outspoken advocate for farm workers rights for many years.

“Long before I was famous,” the actress told The Hollywood Reporter.

She has spoken to Congress and campaigned for fair work legislation for U.S. farmworkers.

Longoria also produced the 2011 documentary Harvest, which takes a closer look at the fate of the hundreds of thousands of children that work as migrant laborers in the U.S. food industry.

“There’s more interest in food than ever before. Everyone is about organic and local and ‘I don’t eat Gluten.’ but no thought is put to the people who pick the food that feeds us all.”
